'''Events''' are driven by the currently selected [[AI Storytellers|AI storyteller]].
  
Events are random occurrences that can strike a colony at any moment. They range from everyday occurrences like passers by, to all out assaults on the colony.
+
Most events that occur create a [[Menu#Letters|Letter]], an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.
  
The player will be notified of an event's occurrence by an envelope icon that will appear down the right side of the screen. Envelopes are color coded according to whether the event is good or bad - blue envelopes denote good events, red envelopes denote bad events, and yellow envelopes denote neutral events.
+
Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.
  
Clicking an envelope will open up the message with a description of the event, and the option to either dismiss the notification or, where possible, go to the location of the event. Alternatively, notification messages can be dismissed without opening via right click.
+
There's a special kind of events called [[Quests]] which work under different rules.

=== Storyteller events ===

These events are controlled by the selected [[storyteller]]. Major and Weather events require at least the Builder [[difficulty]] to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

:{{For|the complete list of events|Events/Anomaly}}
 +
 +
Events from the [[Anomaly]]{{AnomalyIcon}} DLC work different from normal events and are intrinsically related to the [[Monolith]] structure. Due to this, all Anomaly events will be listed on its own page.
 +
 +
== Major threats ==
 +
Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the [[raid points]] mechanic; generally increasing in strength with wealth, colonist count, and [[difficulty]].
  
<!-- The variables below are defined as the total weight of all diseases in the biome, as defined in the biome's XML sheet. E.g.: -->
+
[[Cassandra Classic]] and [[Phoebe Chillax]] both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events ''will'' occur during each OnDay cycle. [[Randy Random]] simply treats a major threat as an event that's less likely to happen.
<!-- Arid has 100, 100, 30, 30, 60, 60. The total is thus 380. Update this if the weights are changed in later patches. -->
+
 
<!-- Total weight DOES NOT change the disease rate... just which disease is picked when a disease roll passes.

=== Major threats generation===
 +
Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates ([[Biotech|Biotech DLC]]{{BiotechIcon}}).

+
For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

=Event Descriptions=
+
=== Raid Generation ===
 +
After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.
 +
 
 +
After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.
 +
 
 +
Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".
 +
 
 +
=== Enemy attack ===
 +
----
 +
{{Main|Raids}}
 +
Commonly known as a '''raid''', this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. [[Raider]]s will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been [[downed]] or killed, or if enough damage to your colony has been done. [[Mechanoid]]s will persist indefinitely.
 +
 
 +
===== Arrival methods =====
 +
Tribal-level factions can't use drop pods, so are limited to assaults.
 +
 
 +
* '''Assaults''': Arrive at the edge of the map, either by walking or by [[drop pod]]. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
 +
* '''Center drop''': Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an un[[roof]]ed [[orbital trade beacon]] if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
 +
* '''Scatter drop''': Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.
 +
 
 +
===== Types =====
 +
* '''Smart''': "Unusually clever" raiders will seek to enter your base while avoiding [[trap]]s and [[turret]]s.
 +
* '''Sappers''': Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
 +
* '''Breachers''': Appear with breach-type raiders, such as tribals with [[breach axe]]s or [[termite]] [[mechanoid]]s. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
 +
* '''Siege''': See below.

 +
==== Siege ====
 +
Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct [[sandbag]]s and [[mortar]]s, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.
 +
 
 +
It is possible to steal a critical material (like [[component]]s) and prevent them from completing construction. This is largely possible with a [[psycast]]er{{RoyaltyIcon}} using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.
 +
 
 +
Strategies to force sieges to attack include the [[sniper rifle]] (watch out for other snipers), a [[psychic animal pulser]], or your own [[mortar]]s.
 +
 
 +
=== Infestation ===
 +
----
 +
{{main|Infestation}}
 +
Infestations come with [[hive]]s and [[insectoid]]s. Hives will produce [[insect jelly]], but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.
 +
 
 +
In order for a regular infestation to spawn, there must be an open area with the [[overhead mountain]] roof, within 30 tiles of a colony [[structure]], and a temperature above {{Temperature|-17}}. Light, and temperatures below {{Temperature|-8}} reduce the chance of infestations.
 +
 
 +
The [[#Too Deep: Infestation|Too Deep: Infestation]] is a separate event. [[Insect]]s can still arrive, but this event has separate mechanics.
  
 +
The [[#Wastepack_infestation|Wastepack infestations]] is a separate event available if [[Biotech]]{{BiotechIcon}} is active. The end effect is similar, but the mechanics are different.
  
  
==Big Threats==
+
=== Manhunter pack ===
 +
----
 +
{{For|the mental state that makes these animals hostile|Manhunter}}
 +
A pack of [[scaria]]-infested animals have arrived, [[Manhunter|hunting]] for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a [[corpse]], which makes them inedible and creates [[rot stink]]. A single animal can arrive and the event will still be called a "pack".
  
===Enemy Attack===
+
Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.
{{main|raider}}
 
  
Commonly known as a raid, this event comes in several types. The size of a raid is determined by your colony's wealth, and the difficulty setting of the AI Storyteller. It is possible for multiple raids to occur at the same time, possibly to the benefit of the player if both raids are from opposing factions.
+
[[File:Manhunter pack.png|300px|Manhunting [[warg]]s]]
  
Different types of raids include:
+
=== Psychic wave ===
 +
----
 +
Appears as Mad Animals: (Animal name). Immediately drives local [[animals|wildlife]] insane, becoming [[manhunter]]. As opposed to a manhunter pack, these animals do not have [[scaria]], and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.
  
====Sieges====
+
As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.
  
Siege raids typically have a party of raiders arrive and set up a small camp along the edge of the map with a number of sandbag walls and mortars which could be High Explosive (HE) or Incendiary. They will fire upon colonists, colony structures and any visitors or other raiders from factions they are hostile to, only stopping to eat and sleep.
+
This event has a [[#Mad animal|variation]] that only affects a single animal, which is not considered a major threat.
  
Siege parties will abandon their camp and any remaining construction to assault the colony when they either run out of artillery shells, all of their siege weapons are destroyed or they suffer significant casualties. Any remaining supplies and objects from their camp and be claimed, deconstructed and used by the player.
+
=== Crashed ship part ===
 +
----
 +
{{For|the help guide|Defense structures#Crashed ships}}
 +
{{For|information on the ship parts themselves|Crashed ship parts}}
 +
A [[crashed ship parts|large piece of an ancient ship]] crashes nearby, along with a pack of [[mechanoid]]s. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.
  
====Assaults====
+
==== Defoliator ship ====
 +
A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in [[hydroponics basin]]s. Crops will end up nearly impossible to grow. If the [[Biotech DLC]] is active, this ship part will also generate [[Pollution]]{{BiotechIcon}} from its center at a rate of 6~7 tiles per day.
  
Assault raids arrive either via the edge of the map or by drop pod. They may assault the colony immediately, or stage for a time before launching their attack, allowing colonists time to take up defensive positions, or to skirmish/counter assault the attackers.
+
==== Psychic ship ====
 +
A ship part projects a psychic drone which negatively affects the [[mood]] of a specific gender. It begins low and grows progressively stronger the longer it stays. [[Psychic sensitivity]] increases or decreases the drone's effect.
  
====Mid-Base Assaults====
+
The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.
  
A group of raiders arrives via drop pods directly in the player's base, leaving little time to prepare. Drop pods may punch through a constructed roof or thin rock roof.
+
====== Drone intensifies ======
 +
If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.

===Psychic Wave===
+
=== Mech cluster ===
 +
----
 +
{{Royalty|Section=1}}
 +
{{main|Mech cluster}}
 +
Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like [[wall]]s, [[turret]]s, and [[unstable power cell]]s. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map [[condition causer]]s, such as sun blockers or EMP dynamos.
  
A psychic wave is a pulse of psychic energy that immediately drives a number of the local [[animals|wildlife]] insane, causing them to attack the nearest human, and any animal that happens to be standing in their way. A psychic wave is not to be laughed at - most of the wildlife in RimWorld is quite fast, and can close the gap to a colonist before they can get off a second shot, often leading to the colonist being overwhelmed.
+
=== Problem causer ===
 +
----
 +
{{Royalty|Section=1}}
 +
{{main|Condition causer}}
 +
A [[condition causer]] has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.
  
===Psychic Ship===
+
</div>
  
This event sees a massive piece of an ancient ship crash down to the surface near (or even in) the colony. This ship part happens to contain a hostile AI core that emits a psychic drone that negatively affects the [[mood]] of all humans on the map. This drone begins low, but grows progressively stronger the longer the ship part remains, therefore it is advisable to destroy the part as quickly as possible. A colonist's psychic sensitivity [[traits]] may worsen or lessen the effect of the drone.
 
  
The AI is also capable of emitting concentrated bursts of psychic energy, driving one colonist to an immediate mental break, or a localized blast that drives all animals in the immediate vicinity insane.
+
== Extreme weather ==
 +
These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.
 +
<div class="mw-customtoggle-XWeather" style="display:center;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">{{Center|Show/Hide Extreme Weather Events}}</div>
  
Upon attacking the part however, a group of mechanoids will emerge to defend the crashed ship part and its AI core. The size of the group is dependent on colony wealth and storyteller difficulty.

===Manhunter Pack===
+
=== Flashstorm ===
 +
----
 +
[[File:FlashstormScreenshot.png|300px|thumb|left]]
 +
"''A freak localized storm is blasting a small area with repeated lightning strikes.''"
  
A pack of man-hunting [[Animal|animals]] have entered the area. They will roam the region, hunting for humanoid flesh. If they see a colonist run behind a door, they will attempt to beat down the door. They'll leave the area in a few days.  
+
'''Flashstorm''' is a localized, intense '''[[lightning]] storm''' within a radius between 45 and 60 tiles. Active lightning will strike between every {{Ticks|320}} to {{Ticks|800}}. Once it finishes, no rain can fall until {{Ticks|30000}} has passed. This can create big [[fire]]s. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.
  
A manhunter pack has 40% more points allocated to enemy spawning than an ordinary raid (i.e. a manhunter pack is 40% bigger than a standard raid), and animals from manhunter packs will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.
+
This can also be caused by the [[Psycasts#Flashstorm|Flashstorm]] Psycast {{RoyaltyIcon}}, but will not show up as a notification.
 +

Tip:
+
=== Toxic fallout ===
To some people, this could be useful for taming. For example: you have tamed the only muffalo on the map and you want to tame another one but sadly there are none on the map.But then, some muffalo attack, you can wound some, heal them, and tame them.
+
----
 +
"''A distant chemical fire has released a plume of poison over this entire region that will slowly settle out of the atmosphere. It will last for anywhere from a few days to an entire season.''"
  
Manhunter packs always consist of a single animal type. Animals eligible to be selected for a manhunter pack include:
+
'''Toxic fallout''' is a dangerous event which causes [[toxic buildup]] to any pawn not under a roof. The fallout also gives a {{--|5}} [[mood]]let for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.
  
*[[Warg]]
+
Toxic buildup from toxic fallout is proportional to both [[Toxic Resistance]] and the [[Toxic Environment Resistance]] of the pawn. Animals have 50% [[Toxic Resistance]], so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their [[corpse]] to immediately rot.
*[[Elephant]]
 
*[[Muffalo]]
 
*[[Boomalope]]
 
*[[Boomrat]]
 
*[[Rhinoceros]]
 
*[[Wild boar]]
 
  
Boars, Wargs, and Muffalo can be very problematic to deal with even with moderately-well defended colonies because the former 3 can easily outrun humans, and they all typically arrive in very high numbers meaning they can easily overwhelm a colony. Boomalopes are arguably easier to deal with in larger numbers as chain reactions can easily happen because of their large 3-square blast radius, meaning that even packs excess of 40 boomalopes can trivially be dealt with by half a dozen of people armed with automatic weapons (e.g. Charge Rifles, LMGs, Miniguns etc.)
+
By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either [[dementia]] or [[carcinoma]]. Death happens at 100% severity. In [[Biotech]],{{BiotechIcon}} both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the [[face mask]], [[gas mask]], [[detoxifier kidney]], [[detoxifier lung]] and several [[genes]].
  
Although manhunter packs are generally a big threat to colonies they might be useful too if the colony is running low on [[meat]]. A strategy to do this is to draft a colonist, place it in a door to shoot a maddened animal until it starts to bleed and move the colonist back to safety, then wait until the animal dies from blood loss, be careful thought since this will draw the attention of surrounding maddened animals making them attack the door where the colonist came from so be ready to repair it immediately; Wait until the other animals from the pack go to sleep or walk away far enough to haul the dead one(s), it's recommended to use a colonist with bionic legs or an improved move speed trait to prevent other animals to catch it up and attack it.
+
Excluding some special cases ([[Anima tree]]{{RoyaltyIcon}}, [[Anima grass]]{{RoyaltyIcon}}, [[Gauranlen tree]]{{IdeologyIcon}}, [[Gauranlen pod]]{{IdeologyIcon}}, [[Polux tree]]{{BiotechIcon}}), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage {{Check Tag|57.51667 base damage ±15%}}. Crops can be protected under a roof, but without a [[sun lamp]], they'll rot anyways. [[Insectoid]]s and [[mechanoid]]s are fully immune.

A bug [[hive]] has emerged! It will slowly spawn [[insectoids|bugs]] as well as produce additional hives. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.
+
=== Volcanic winter ===
 +
----
 +
"''A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months.''"
  
Infestations will only spawn under an overhead mountain. If all insects are killed, the hives will slowly die out after a while. Hives also bring glow pods that glow for 20 days (as long as they’re installed) and can be reinstalled or sold.
+
'''Volcanic winter''' lowers the temperature and natural [[light]], which in turn weakens [[solar generator]]s and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.
  
Hives also produce insect Jelly, so if you could trap the hives via walls and doors, you could potentially farm the insect Jelly, though the insects are liable to digging out.
+
To be specific, the temperature is reduced by {{Temperature|7}} and the light by 30% over the course of {{Ticks|50000}}. The wildlife density is cut by half, and pawns can no longer enjoy their time outside.
  
== Special ==
+
</div>
Special events only occur during certain circumstances.
 
  
=== Ancient Danger ===
 
This event is related to map generation and may not appear on every map.
 
  
''"As (Colonist Name) draws near the ancient wall a sense of foreboding overcomes him. (S)He isn't sure why, but (s)he feels this dusty structure may contain great dangers"'' -message that appears when the first colonist walks near
+
== Random Events ==
 +
These are the 3rd set of events able to be triggered by the [[storyteller]]. Internally, Random Events are classified as either good, bad, or quest.
  
A [[Ancient structure|walled out area]] of the map that can contain either [[cryptosleep casket]]s, [[insectoids|bugs]], [[mechanoid]]s, treasure, or some combination of those. Open at your own risk by blowing a hole in the wall or deconstructing a section. The [[cryptosleep casket]]s usually contain humans, but may be empty.  Opening or attacking any casket will cause all the others to open instantly.  The people inside the caskets may or may not be dead.  If alive, they may or may not be armed and hostile.  It's even possible for pawns incapable of Violent to melee attack. If they are not hostile and can walk, they will try to escape.  Any alive spacers inside may be captured and recruited, with usually a low recruitment difficulty percentage.
+
=== Quests ===
 +
{{Main|Quests}}
 +
Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.
  
{{asof|A14}} pod people sometimes come with [[plasteel]], [[component]]s, and [[gold]]. As of other recent updates, [[luciferium]] can be found in these buildings.  Ancient structures may include other treasures like psychic lances and pulsers.  The caskets can be Claimed and used or deconstructed by the colony.
+
=== Good ===
 +
<div class="mw-customtoggle-RandomGood" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Good Random Events</div>
  
=== Faction Assistance ===
+
<div  id="mw-customcollapsible-RandomGood" class="mw-collapsible"><!-- mw-collapsed -->
This event occurs at random only during attacks and only if relations with other factions are friendly.
 
  
When any hostiles appear, friendly factions may send fighters on their own to assist the player at no cost. Optionally, the player can use the [[comms console]] and call upon friendly factions to send a group of fighters to assist them at a cost of relations. It is important to observe relations between the friendly faction and the raiders however, as friendly factions won't assist you against people that they aren't hostile to.
+
==== Ambrosia sprout ====
 +
[[File:Ambrosia sprout.png|300px|right|thumb|An ambrosia sprout among the trees]]
 +
[[{{Q|Ambrosia bush|Image}}|48px|left|frameless]]{{quote|A grove of the mysterious [[ambrosia bush]] has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive [[Ambrosia|fruit]].}}
 +
Ambrosia bushes are the only way to harvest [[ambrosia]], a safe [[mood]] boosting [[social drug]]. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.
  
Keep in mind that if your own colonists assist in their attack, your errant attacks can still damage your relations with that faction if your colonists hit them.  Also, rescuing and healing any of their downed attackers will improve relations once they exit the map.
+
It can only happen in the following [[biomes]]:
 +
<div style="width:500px"><ul class="ul-column-width-150">
 +
* [[Tropical rainforest]]
 +
* [[Tropical swamp]]
 +
* [[Temperate forest]]
 +
* [[Temperate swamp]]
 +
* [[Boreal forest]]
 +
* [[Arid shrubland]]
 +
</ul></div>
  
===Refugee Chased===
+
==== Animals join ====
This event will not trigger if the colony doesn't have hostile relations with any faction.  Pirate band factions should always be hostile since any attempt to improve relations with them is disregarded by design.
+
Tamed dogs or [[farm animals]] from off-map join your colony.
  
When this event triggers a window appears stating that an individual calls you, via radio, from nearby seeking refuge from a faction (hostile to you) that is chasing them. The player may choose 'Offer safety' or 'Ignore the message'. Ignoring the message will end the event. Offering safety will spawn the individual as a colonist at the map's edge who proceeds towards the colony. Shortly thereafter, the pursuing faction arrives in the form of a raid entering the map where the refugee appeared. The number of pursuing faction members depends on the current size and strength of the colony.
+
==== Animal self-tamed ====
 +
[[File:Thrumbo self-tamed.png|300px|right]]
 +
A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.
  
=== Traitor ===
+
For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.
This event is disabled and should be disregarded.
 
  
<!--This event text is intentionally removed from view since this event is disabled.
+
==== Aurora ====
When this event occurs, a colonist is suddenly revealed to be an agent of one of the colony's enemies - they will attempt to flee, but can be recaptured (and/or punished) before they do so.
+
An aurora lights up the night sky, giving a +14 mood boost to anyone who is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.
-->
 
  
==Small Threats==
+
Despite the event text stating that it will "make the night brighter", it does not actually affect the light level.
  
===Mad Animal===
+
==== Cargo pods ====
 +
[[File:Cargo pods.png|300px|right]]
 +
From time to time, [[transport pod|cargo pods]] will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become [[steel slag chunk]]s, which can be refined into usable metal at an [[electric smelter]]. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.
 +
{{Clear}}
  
When this event occurs, a single random animal on the map is driven insane. Like with the psychic wave, the insane animal will charge toward the nearest human, attacking any other animal or obstacle (doors, etc.) in its way. This event is particularly dangerous if a Boomalope or Boomrat turns, as they explode upon death and the latter can also reliably catch up to an unmodified human regardless of traits.
+
==== Herd migration: (Animal) ====
 +
[[File:Thrumbo herd migration.png|300px|right]]
  
===(Animal) Revenge===
+
A large herd of [[animal]]s is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.
  
Similar to the Mad Animal event, an animal that was harmed will go mad and target whomever hurt it.  The game will notify you if such an animal chosen for Hunting will likely attack if harmed, usually predators.  Occasionally, all nearby pack members of that animal's species may start attacking their attacker, possibly killing them.
+
This event only occurs in the following biomes:
  
==General Bad==
+
<div style="column-count:3; width:350px;">
 +
* [[Sea ice]]
 +
* [[Ice sheet]]
 +
* [[Tundra]]
 +
* [[Desert]]
 +
* [[Extreme desert]]
  
===Flash Storm===
+
</div>
  
A localized, intense lightning storm in one area of the map. Causes big [[fire]]s. Clicking the envelope icon offers the option to jump to the location where the strikes will be.
+
==== Party ====
 +
One of your colonists will throw a party around a [[party spot]], or if unavailable, a gather spot ([[table]] or [[campfire]]). Colonists will continually get mood buffs the longer they attend a party.{{Check Tag|Detail|Stacking behavior for party duration?}} Each stack adds {{+|0.8}} to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have [[beer]]s and [[smokeleaf joint]]s, if available, and eat [[meal]]s even when not hungry.
  
===Eclipse===
+
Pawns that don't attend won't get mood buffs. Players may have to [[draft]] and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a [[raid]] happens, then the party will be called off.
  
During a solar eclipse, solar generators cease producing power, and outdoor crops stop growing. Be sure to have power and food stored for times like these, or an eclipse coupled with a raid could be the death of an unprepared colony.
+
==== Psychic soothe ====
 +
[[File:Psychic soothe.png|300px|right]]
  
===Solar Flare===
+
When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the [[Psychic Sensitivity]]) to all colonists of a randomly chosen sex. It can be considered the opposite of the [[#Psychic drone|Psychic Drone]], but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.
 +
{{Clear}}
  
Solar flares cause all electrical items on the map to stop working for the duration of the event. Solar flares are particularly dangerous for colonies that rely on turrets for defense, as they will be vulnerable to any raid that arrives during the solar flare.
+
==== (Trader type) ====
 +
This event, without a faction mentioned, occurs when an orbital [[trade]] ship passes near the colony and you have a powered [[comms console]]. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.
  
On cold weather maps, Hydroponic farms will cease to grow crops regardless of the temperature, and heaters will fail causing ground based crops to fail as well.
+
You need to build [[orbital trade beacon]]s before contacting them so you can beam [[silver]] and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.
  
===Psychic Drone===
+
==== (Trader type) from (Faction) ====
 +
This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the [[comms console]] at a hit to good will or randomly on their own with no penalty.
  
Drone in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz."
+
==== Transport pod crash ====
 +
[[File:Rescuee joined your group.png|300px|thumb|right|Since you rescued him/her. Character joined your group!]]
 +
A [[downed]] and injured occupant falls from the sky, containing members of a [[faction]] or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed.
 +
The pawn can also be a [[xenotype]]{{BiotechIcon}} that doesn't have any factions on the planet.{{Check Tag|Detail needed|Which xenotypes specifically can be used? All the default types? Wb Sanguo? Wb preferred xenotypes? Wb custom ones from made during game genration? Wb custom ones made after?}}
  
A Psychic Drone phenomenon affects all colonists of a randomly chosen sex, negatively influencing their mood. Colonists have no choice but to endure it as the point of origin is off map. Psychic sensitivity [[traits]] can be a big factor in the threat posed by this event.
+
Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead [[Prisoner|capture]] a non-hostile person, but their faction (if not spacer) will turn hostile.
  
===Faulty Conduit Explosion===
+
===== Paralytic abasia =====
 +
{{Royalty|section=1}}
 +
A transport pod can crash with a person with [[paralytic abasia]], a [[disease]] which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.
  
This event can only occur if there is at least one battery with stored power.
+
===== Baby =====
 +
{{Biotech|section=1}}
 +
A transport pod may crash with a [[baby]] instead of the regular occupant, and will always appear as a friendly faction/neutral refugee/unaffiliated. You can choose to ignore it and let it starve to death, or adopt the baby by selecting it and click "Adopt". Rarely, the corpse of the baby's parent can also appear next to it, still in pristine condition.
 +
{{clear}}
  
At any moment, a power conduit may suffer a fault, causing it to explode and expel all stored power in the attached circuit in the process. The amount of stored power directly affects the size of the explosion, up to a maximum of 15 squares in diameter from a total of 90,000 Wd stored. The explosion can damage any nearby structures, items and colonists, as well as catch anything flammable nearby on fire. The explosion will often completely destroy the one section of power conduit where it occurred, cutting off power to anything past it unless there is another path for the electricity to flow around this damage.  Laying redundant pathways throughout your colony prevents this.
+
==== Wanderer joins ====
 +
A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.
  
===Mysterious Blight===
+
With [[Ideology]]{{IdeologyIcon}}, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an [[Ideoligion]]'s event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.
  
This event destroys most if not all of the colony's planted crops across the map, including crops hydroponic crops grown indoors. Be sure to keep a reserve of food to counter the issue or resort to hunting until more food can be grown.

Note that [[Devilstrand mushroom]]s are immune to this event.
+
==== Wild (wo)man wanders in ====
 +
A random person with no faction wanders into your colony and will mill about the map. You have the option to [[Tame]] this person with a minimum [[Skills#Animals|Animals skill]] of {{Q|Human|Minimum Handling Skill}}. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or [[Slavery|enslave]]{{IdeologyIcon}} them like regular prisoners, they must be tamed or rescued.
  
===Heat Wave===
+
Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.
  
A heat wave sweeps the colony, driving [[temperature]] up for several days. Colonists will complain about the heat, especially sleeping in it if their rooms are not properly cooled. Additionally, things might rot in inadequately cooled freezers. There is also a chance for a fire to randomly appear on the map which can quickly spread and burn down an entire colony.
+
These wild (wo)men may have random Ideoligion with [[Ideology]].
  
Heat waves sometimes can be deadly to unprepared colonies, mostly tribal ones since they have it harder to build air conditioners since they start without that technology and it takes longer to unlock it. For them it's advised to use passive coolers in rooms or food stockpiles to prevent food from rotting quickly and colonists and animals from getting a heatstroke.  [[Duster]]s and [[cowboy hat]]s provide heat insulation for colonists, protecting them while they're awake. They don't wear them to bed though.
+
Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.
  
Additionally some animals will leave the map if the temperature gets higher than they can stand.

===Cold Snap===
+
==== Traveler Visit ====
 +
{{:Traveler}}
  
A cold snap makes the [[temperature]] of a colony drop for several days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.  
+
==== Visitor(s) ====
 +
Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.
  
While this is generally good for item preservation, It can kill off crops and influence colonist moods and cause Hypothermia if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible, potentially causing animals to starve to death.  [[Duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake. They don't wear them to bed though.
+
Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.
  
===Alphabeavers===
+
==== Royal Tribute Collector ====
 +
{{Royalty|section=1}}
 +
{{Main|Royal tribute collector}}
 +
If you are not hostile to the [[Empire]], Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept [[gold]] and [[prisoner]]s in exchange for [[Titles#Honor|Honor]].
  
A group of ravenous wood-munching [[alphabeaver]]s appears at the edge of the map. They will continually eat [[trees]] (including any you're farming) and [[Saguaro_cactus|Saguaro cacti]] until they consume them all, unless you eradicate them first.
+
==== Gauranlen pod sprout ====
 +
{{Ideology|section=1}}
 +
{{quote|A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic [[Gauranlen tree]]. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.}}
  
It is recommended to bring more than one colonist to exterminate them if you choose to. If one turns manhunter, the whole pack will become manhunters, which can turn individually weak beavers into a small army of killing machines.
+
A [[Gauranlen pod|pod]] will appear somewhere with the current map. Harvesting it yield 1-2 [[Gauranlen seed]]. This event occurs roughly every 60 [[time|days]] in every [[biome]] except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for [[Ideoligion#Tree connection|tree connectors]]. This event can also occur if an [[Ideoligion]]'s ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.
  
===Toxic Fallout===
+
==== Polux tree sprout ====
 +
{{Biotech|section=1}}
 +
A [[polux tree]] may appear whenever there is enough [[pollution]] around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.
  
A distant chemical fire has released a plume of poison over this entire region. Any person or creature not under a roof will be slowly [[Ailments#Toxic_Buildup|sickened]] by the toxic dust settling out of the atmosphere. It will last for anywhere between a few days to over a month.
+
</div>
  
Plants will wither under the fallout. This event will usually wipe out all wild animals and poses a serious danger to tamed ones unless they are restricted to an area under a roof.
+
=== Bad ===
Toxic Buildup, which is caused by toxic fallout, can cause [[Injury#Old_Age|dementia]], and eventually a carcinoma (according to game files) if it progresses far enough. However, the latter is treatable via a lengthy operation with the use of at least [[Medicine]], or removed via a surgery.
+
<div class="mw-customtoggle-RandomBad" style="display:inline-block;background:rgba(128,128,128,0.5);color:white;padding:10px;border-radius:5px;outline:none;user-select:none">Show Bad Random Events</div>
 +
<div  id="mw-customcollapsible-RandomBad" class="mw-collapsible"><!-- mw-collapsed -->
  
If you are running low on food, wait for animals to die and then butcher their corpses.
+
==== Beavers! ====
 +
A group of ravenous tree-munching [[alphabeaver]]s appears at the edge of the map. This only occurs in the [[arid shrubland]] and [[tundra]], and only when the outdoor [[temperature]] is above the alphabeaver's [[minimum comfortable temperature]] of {{Temperature|{{Q|Alphabeaver|Min Comfortable Temperature}} }}. It will not reoccur for 30 days.
  
===Volcanic Winter===
+
Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat [[trees]] and [[Saguaro cactus|Saguaro cacti]] they can reach, including [[anima tree]]s{{RoyaltyIcon}}, [[gauranlen tree]]s{{IdeologyIcon}}, [[polux tree]]s{{BiotechIcon}} and any trees you're farming. Alphabeavers will not and cannot eat the {{Icon Small|wood}} [[wood]] item, [[wood]]en buildings, or any other item made out of wood.
  
A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop, plants will suffer for lack of sunlight and solar panels will not produce as much power. It could pass in a few weeks, or it might last many months.
+
The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.
  
Volcanic Winters also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in from Spring-Summer when there'd normally be many), which can easily lead to meat shortages and famine if you don't have sufficiently large farms for your colony.
+
==== Birthday ====
 +
Character gains an age-related illness, such as [[bad back]] or [[cataract]]s. They may be cured by using the [[healer mech serum]], [[luciferium]], a [[biosculpter pod]]{{IdeologyIcon}}, or the Scarless [[gene]]{{BiotechIcon}}. Some may be 'cured' by replacing the affected parts with bionics.
  
===Poison Ship===
+
Due to age or a pre-existing health condition, they can also have a [[heart attack]].
 +
{{Clear}}
  
A Poison Ship event kills plants in an expanding circle, eventually reaching the entire map. Do not confuse this with the plant killing snow aura present on both Poison Ships and Ancient Crashed Ships. The poison kill crops randomly, including plants grown in [[Hydroponics basin]]s. The affected areas will ultimately have dramatically reduced chances of maturing simple crops, and slower crops will end up nearly impossible to grow.
+
==== Blight ====
 +
{{main|Blight}}
 +
[[File:Crop blight.png|200px|thumb|right|Blighted crops with an indicator above them.]]
  
===Breakdown===
+
Blight is a disease that infects [[domesticated plants]] with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. [[Tree]]s, [[Wild Plants|wild]], [[Decorative Plants|decorative]] plants, and [[devilstrand mushroom]]s are immune to blight.
  
One of your machines will break down and will not work until repaired with a [[component]].  If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.
+
Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.
  
===Disease (Name)===
+
It will not reoccur for 30 days.
  
One or several of your colonists will be afflicted with a sickness. The chance of which sickness infected with depends on the biome.
+
==== Disease ====
 +
Colonists (including [[prisoner]]s and [[slave]]s{{IdeologyIcon}}) or animals will gain a random [[disease]]. [[Biome]] influences both the amount of disease and its selection. Multiple pawns can get a disease at once, but diseases never spread between pawns. Disease events are controlled separately from other events by your [[storyteller]].
  
==General Good==
+
[[Traits#Sickly|Sickly]] pawns will get sick with a MTB of 30 days, independently of the rest of your colonists.
===Self Tame===
 
  
A random animal on the map becomes self tamed.
+
==== Eclipse ====
 +
A moon has moved in front of the sun, causing an eclipse. Without [[light]], [[solar generator]]s won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.
  
===Farm Animals Wander===
+
If reliant on solar power, make sure to have [[battery|batteries]] for times like these, or an eclipse raid can be extra threatening.
  
Some tame farm animals wander to and join the colony. Mostly cows, pigs and chickens, occasionally with the random dog.
+
Pawns with the [[Ideoligion#Eclipse|Eclipse: Beautiful]] precept{{IdeologyIcon}} will receive a {{+|5}} moodlet for seeing an eclipse.
  
===Trade Ship In Range===
+
It will not reoccur for 15 days
  
When an orbital [[trade]] ship passes near the colony, players may spend silver to obtain resources or weapons, or alternately sell excess resources or weapons for silver. You will only receive this notification if you have built a [[comms console]] and it's powered.
+
==== Heat wave ====
 +
{{stub|section=1|reason=Needs details. What's the chance for a fire to occur?}}
 +
A heat wave sweeps the colony, driving outdoor [[temperature]]s unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by {{Temperature|17}} over 12000 game ticks (4.8 in-game hours). There is also a chance for a [[fire]] to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least {{Temperature|20}}, and will not reoccur for 30 days.
  
===Pirate Merchant In Range===
+
The major risks are [[cooler]]s failing to freeze food, and [[heat stroke]] to your colonists and animals. Summer clothing like [[cowboy hat]]s and [[tribalwear]] can mitigate the heat, and [[passive cooler]]s can help make indoor temperatures bearable.
  
Slave traders are rarer than regular traders.  They traffic in that most precious of cargo: fresh colonists. Players can also sell unwanted prisoners to slave traders, however any colonists without the psychopath trait will suffer a mood penalty for doing so and the colonist doing the selling will receive a social penalty. As with regular trade ships, you will only receive this notification if you have built a [[comms console]] and it's powered.
+
Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.
  
===Migrant===
+
==== Cold snap ====
 +
A cold snap strikes the colony, driving outdoor [[temperature]] unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by {{Temperature|20}} over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of {{Temperature|0|15}}, and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.
  
This event sees a random colonist arrive via the map edge and join the colony immediately. They will most likely be naked, so have some spare clothes ready just in case!
+
While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause [[Ailments#Hypothermia|hypothermia]] if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.
  
===Cargo Pods===
+
[[Jacket]]s, [[duster]]s, [[parka]]s and [[tuque]]s provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.
  
From time to time, cargo pods from the wreckage of the ship will fall out of orbit and land on your map. These pods contain a random amount of resources. The remains of the pods become pieces of slag, which can be refined into usable metal at an [[electric smelter]].  The pods have a chance of crashing through the roofs and walls of any buildings.
+
Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.
  
===Escape Pod===
 
  
Rarely, an escape pod will crash land nearby. The occupant will be incapacitated, but can be rescued and treated or be [[Prisoner|captured]] and possibly recruited into the colony. It's possible for the person to be related to someone in the colony. This is indicated on the notice as <tt>Escape pod (relationship)</tt>.  Usually, this pawn will join the colony once healed. Still, the pawn has the opportunity to walk off on their own once healed. If you do nothing, they have the same opportunity to stand on their own after awhile and walk off, depending on their injuries.
+
==== Mad animal ====
 +
A single random animal on the map turns [[manhunter]], like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.
  
For a near-guaranteed way to recruit them, capture rather than rescue them. Their recruitment difficulty percentage is usually low and this will also train your warden's Social skill.
+
Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive [[boomalope]] and [[boomrat]], are bigger threats.
  
===Psychic Soothe===
+
==== Psychic drone ====
 +
{{For|the moodlet|Mood#Exotic}}
 +
'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a [[Mood#Exotic|strong negative moodlet]]. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). [[Psychic Sensitivity]] will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days.
  
When this event triggers it gives a positive mood modifier (+15) to all colonists of a randomly chosen sex. The event lasts between 1.5 to 3.5 days. It can be considered the opposite of the [[#Psychic Drone|Psychic Drone]].
+
Colonists have no choice but to endure it, as the point of origin is off-map. [[Psychic foil helmet]]s, [[drug]]s, and other mood-enhancers can help deal with the effects. Animals are not affected.
  
===Friendly AI===
+
==== Solar flare ====
 +
Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. [[Wood-fired generator]]s and [[chemfuel generator]]s will still burn fuel during this time.
  
Occasionally, a friendly AI will contact the colony and reveal the location of a working [[ship]] that the colonists can use to escape this Rimworld. The ship is located in a map tile that is always far away, usually requiring several stops along the way to resupply.
+
* Colonies that rely on turrets for defense will become vulnerable to raids.
 +
* Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. [[Campfire]]s and [[passive cooler]]s are low-tech options that work even in a solar flare.
 +
* Crops in a [[hydroponics basin]] will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
 +
* Occasionally an [[Trade#Orbital|orbital trade ship]] may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''''<trader> has left comms range"'' notification while unaware of their presence. If a ship leaves ''during'' a solar flare, you ''will'' be notified that the trader has left, although this is only a minor message in the upper right of the screen.
 +
* The colony is immune to the effects of a solar flare while also undergoing [[unnatural darkness]]{{AnomalyIcon}}
  
===Area Revealed===
+
Due to its length, most of the adverse effects are manageable.
  
This event happens when a hidden area has been opened up on the map. This usually happens while mining or deconstructing a derelict building on the map.  You could reveal new mineral riches, new farmland, new animals, new threats... or absolutely nothing.
+
==== Zzztt ====
 +
This event can occur anytime a [[power conduit]] has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to [[weather|rain or snow]]. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect [[Hidden_conduit|hidden conduits]], meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.
  
Sometimes entrances to these areas can be seen on the map.  Look along the edge of a mountain and sometimes on the one visible edge block you'll see that the block has inward facing edges as well.
+
The following buildings short circuit due to weather:
 +
<div style="column-count:3; width:700px;">
 +
* [[Sun lamp]]
 +
* [[Tube television]]
 +
* [[Flatscreen television]]
 +
* [[Megascreen television]]
 +
* [[Comms console]]
 +
* [[Multi-analyzer]]
 +
* [[Vitals monitor]]
 +
* [[Battery]]

 +
* [[Electric smithy]]
 +
* [[Machining table]]
 +
* [[Electric stove]]
 +
* [[Electric smelter]]
 +
* [[Biofuel refinery]]
 +
* [[Fabrication bench]]
 +
* [[Hi-tech research bench]]
 +
* [[Electric crematorium]]
 +
* [[Heater]]
 +
* [[Lightball]]{{IdeologyIcon}}
 +
* [[Loudspeaker]]{{IdeologyIcon}}
 +
* [[Autobong]]{{IdeologyIcon}}
 +
</div>
  
===Party===
+
Short circuits will either result in a [[fire]], or, if any [[battery|batteries]] are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 [[Damage Types#Flame|Flame damage]] and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 [[Damage Types#Bomb|Bomb damage]], which can extinguish fires. The fault will also discharge all stored power in batteries in the process.
  
One of your colonists will throw a party, improving the moods of all attendees for some time and providing an opportunity for rapid Social changes.  They will usually have [[beer]]s and [[smokeleaf joint]]s if available.  Note that the player may have to wake up any sleeping colonists such as Night Owls or otherwise distract other colonists from their work so that they attend the party.  An easy way to do this is by quickly drafting and undrafting them.
+
The explosion radius is controlled by the following equation:
  
The party by default will happen around an item checked as a Gather Spot such as a table, but may be overridden by building a [[party spot]].
+
{| class="wikitable"
 +
| '''Explosion Radius''' = '''clamp'''( '''sqrt'''(Sum of all stored power) * 0.05, 1.5, 14.9)
 +
|}
  
===Goodwill===
+
Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.
  
This notification will appear once relations have been improved with a Hostile faction enough that they will no longer be hostile. Common ways to improve relations include releasing prisoners or gifting silver via the [[comms console]].

Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only [[Battery|batteries]] and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.
  
==Neutral==
+
==== Transport pod crash (Ghoul) ====
 +
{{Anomaly|section=1}}
 +
A transport pod may crash with a [[ghoul]] instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.
  
===Rare Thrumbos===

==== Gray pall ====
 +
{{Anomaly|section=1}}

A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a {{bad|-6}} '''gray pall exposure''' moodlet, while colonists under a roof will have {{bad|-3}} '''gray pall'''. The pall is otherwise not dangerous and disappears after 1-2 days.
 +
</div>
  
One or more [[thrumbo]]s will spawn at the edge of the map, staying around for awhile to eat anything they can, including your crops.  The player can attempt to hunt or tame them, both of which are very difficult.  If no action is taken, they will leave on their own after a few days.

== Incidental Events ==
 +
:{{For|a detailed list of these events|Events/Incidental}}
 +
These events aren't triggered by the [[storyteller]]. Instead, they come from various other game mechanics.
 +
For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.
  
Occasionally, one or more faction members will travel from one map edge to another, which may work in the player's favor should the group run across mutual enemies.
+
== World incidents ==
 +
:{{For|a guide to survive these events|World Quests Guide}}
 +
These are events related to/only triggered on the overworld.
 +

===Faction Visit===
+
<div id="mw-customcollapsible-WorldEvents" class="mw-collapsible"><!-- mw-collapsed -->
  
A friendly faction visit consists of a group of friendly faction members arriving and milling about the player's colony. They currently possess no higher purpose, but their arrival could prove advantageous if the colony is assaulted by a mutual enemy while they are present.
+
==== Attack begun ====
 +
This notification will appear when a [[caravan]] has arrived at a settlement chosen for attacking.
  
===Relationship===
+
==== Bandit camp opportunity ====
 +
{{See also|Offense tactics}}
  
This event is similar to the above visits, only that one of the visitors has a relation to one of your colonists or prisoners.
+
Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.
 +
 
 +
The bandit camp will time out and are weaker than regular enemy bases.
 +
 
 +
Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.
 +
 
 +
==== Caravan ambushed / (manhunters) ====
 +
While traveling, one of your [[caravan]]s are attacked. The game will give you a mini map to defend it.
 +
 
 +
The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.
 +
 
 +
===== Caravan battle won =====
 +
This event will tell you if your people won their fight, and can reform the caravan on the world map.
 +
 
 +
==== Caravan arrived at (Location) ====
 +
This is a simple notification that your caravan has arrived at their destination.
 +
 
 +
==== Caravan lost ====
 +
[[File:Caravan destroyed.png|thumb|right|400px]]
 +
All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.
 +
 
 +
If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.
 +
{{Clear}}
 +
 
 +
==== Caravan meeting by (Caravan ID) ====
 +
This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.
 +
 
 +
==== Caravan ready ====
 +
Once you've designated a [[caravan]], you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.
 +
 
 +
==== Demand ====
 +
A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.
 +
 
 +
You can see their number when they are demanding you hand over items.
 +
 
 +
==== Peace talks ====
 +
[[File:Peace talks.png|thumb|right|300px]]
 +
 
 +
A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.
 +
 
 +
To participate, you will need to send a [[caravan]] with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.
 +
 
 +
There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain social skill.
 +
 
 +
{| class="wikitable"

|-
 +
| '''Peace talk triumph''' || The peace talks were very successful, giving a great boost to relations from 50 to 75. In addition, the faction will give a farewell gift worth between 500 and 1500 silver. <br/>Despite your triumph, if you don't manage to bring relations above 0, they will still remain hostile. || 0.1

In addition, the angered faction sends a group of attackers after your negotiating party. || 0.05
 +
|}
 +
 
 +
===== Outcome chances =====
 +
The actual outcome chances are dependent on the negotiator's Diplomacy Power stat, after going through a simple curve. To do this, the game calculates the bad outcome factor, of the negotiator first.
 +
 
 +
* At 0% power, the bad outcome factor is 4.
 +
* At 100% power (healthy, lvl 10 Social), the bad outcome factor is 1.
 +
* At 150% power (healthy, lvl 20 Social), the bad outcome factor is 0.4.
 +
 
 +
The new weight of each outcome is calculated afterwards.
 +
 
 +
* Triumph = 0.1 * ( 1 / Bad Outcome Factor)
 +
* Success = 0.55 * ( 1 / Bad Outcome Factor)
 +
* Flounder = 0.2
 +
* Backfire = 0.1 * Bad Outcome Factor
 +
* Disaster = 0.05 * Bad Outcome Factor
 +
The sum total of the new weights is then calculated.
 +
 
 +
Finally, the probability of each outcome is calculated:
 +
 
 +
{{Math|big=0|Probability of each outcome {{=}} New Weight &divide; Sum Total of Weights}}
 +

==== Rescuee joins ====
 +
Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.
 +
 
 +
=== Sub-events ===
 +
These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.
 +
 
 +
==== Ambush ====
 +
[[File:Incapacitated refugee Ambushed.png|thumb|right|400px]]
 +
Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.
 +
{{Clear}}
 +
 
 +
==== Sleeping mechanoids ====
 +
When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.
 +
</div>
 +
 
 +
== Game endings ==
 +
When these happen, they signify that your game has ended, one way or another.
 +
<span class="mw-Gameend_toggle" style="font-size:small; display:inline-block; float:right;"> </span>
 +
<div  id="mw-Gameend_collapsible" class="mw-collapsible mw-collapsed" data-expandtext="Reveal" data-collapsetext="Hide">
 +
 
 +
==== Game over ====
 +
[[File:Game over.png|400px|thumb|right|Welp, time to start a new game I guess...]]
 +
This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that [[Endings#Colony_End|everyone is gone or dead]], and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.
 +
 
 +
Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.
 +
 
 +
Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the [[Scenario_system|scenario editor]] as the Wanderer'''s''' <small>(plural)</small> Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.
 +
{{Clear}}
 +
 
 +
==== Planetkiller ====
 +
[[File:Game over planetkiller.png|400px|thumb|right|Ouch.]]
 +
"''An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life.''"
 +
 
 +
This event can only happen by configuring the starting scenario.
 +
 
 +
When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.
 +
 
 +
Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.
 +
{{Clear}}
 +
 
 +
==== Ending - The Archonexus Core ====
 +
For specifics, see [[Endings#The_Archonexus]].
 +
 
 +
Once it happens, your colony is succesfully noticed by an archotech. What happens next is left to especulation.
 +
 
 +
Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.

=== Bonded animal's death ===
 +
[[File:Bonded animals death.png|300px|thumb|right|Bonded animal dies affecting the owner's mood.]]
 +
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.
 +
 
 +
An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.
 +
{{Clear}}
 +
 
 +
=== Bonded master's death ===
 +
Both of these bonded death events were simplified into the [[Events/Incidental#Death|Death: (Pawn)]] event.
 +
 
 +
The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.
 +
 
 +
When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.
 +
 
 +
This is one of the only situations where animals can have non-manhunter mental breaks.
 +
 
 +
=== Breakdown: (Machine) ===
 +
In previous versions, this was its own event. Now it's just a notification.
 +
 
 +
One of your machines will break down and will not work until repaired with a [[component]]. If this happens to a [[hydroponics basin]], any crops in it will wither and die unless repaired immediately.
 +
 
 +
This only applies to machines using electricity.
 +
 
 +
=== Tornado ===
 +
A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually [[:File:The tornado has left the map.png|leave the map]].
 +
 
 +
Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.
 +
 
 +
Naturally forming tornadoes are exclusive to Beta 18. You can still use the [[Tornado generator]] to spawn them in for defense purposes.
 +
</div>
 +
 
 +
== Event data ==
 +
Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the [[storyteller]]'s population intent factor. They become more common if you have few colonists, and rare if you have many.

Events are driven by the currently selected AI storyteller.

Most events that occur create a Letter, an envelope icon on the right side of the screen. Other events will pause the game and pop up a window where the player must make a choice. Usually, the color of the envelope will suggest the severity of the event; blue envelopes are good events, grey is neutral, yellow is bad, and red denotes direct threats.

Many event titles are variable. They can mention location, pawn and faction names, specific buffs or debuffs, or even have countdowns for the time variable events.

There's a special kind of events called Quests which work under different rules.

Event List [edit]

For ease of navigation, events are subdivided into 3 groups: Storyteller events, Incidental events, and World events.

Storyteller events[edit]

These events are controlled by the selected storyteller. Major and Weather events require at least the Builder difficulty to be able to trigger.

Due to wiki limitations, it isn't possible to link directly to a collapsed section. To address that, this toggle will open all relevant sections.

Anomaly events[edit]

Events from the AnomalyContent added by the Anomaly DLC DLC work different from normal events and are intrinsically related to the Monolith structure. Due to this, all Anomaly events will be listed on its own page.

Major threats[edit]

Major threats can appear from Base Builder difficulty onwards. They mostly consist of direct attacks to your colony. Their size depends on the raid points mechanic; generally increasing in strength with wealth, colonist count, and difficulty.

Cassandra Classic and Phoebe Chillax both treat major threats separately from other events; they cycle between "OnDays" and "OffDays", where a certain amount of major events will occur during each OnDay cycle. Randy Random simply treats a major threat as an event that's less likely to happen.

Show/Hide Major Events

Major threats generation[edit]

Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Storyteller major threats are fired according to the Storyteller's schedule. Randy's "schedule" is a random firing mechanic. Quest major threats must be explicitly accepted by the player. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates (Biotech DLCContent added by the Biotech DLC).

For Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Each type of major threat has a specific weight. Some major threats may not be possible at a specific time and would have a weight of 0. For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats are gated behind Raid Point amounts. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.

Raid Weights
Raid type Vanilla DLC enabled
Raid 7.40 7.40
DefoliatorShip 2.00 0.40
DronerShip 2.00 0.40
MechCluster Content added by the Royalty DLC 0.00 1.90
Manhunter 2.00 2.00
MassInsanity 1.30 1.30
Infest 2.70 2.70
Wastepack Infest Content added by the Biotech DLC 0.00 0.024
Problem Causer Content added by the Royalty DLC 0.00 0.95

Raid Generation[edit]

After the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Each faction is given a weight and all hostile factions are considered separately. Human factions each have a weight of 1. The mechanoid faction's weight changes with raid Points. As Raid Points go up the weight of the Mechanoid Faction Increases. Mechanoids weight is 0 until 300 raid points. The weight of human factions can become 0 at extreme temperatures.

After the faction is chosen, the attack type is chosen. Each attack type has a weight. Some factions do not have all possible attack types. For example, Tribals cannot Siege. After the attack type is chosen, arrival method is chosen. Each arrival method has a weight. Some weights change based on raid points. Some arrival methods are not possible with some factions. Some attack types only arrive via certain methods.

Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Each faction has defined raid compositions like the "all sniper" or "all melee attack".

Enemy attack[edit]


Commonly known as a raid, this event comes in several types. It is possible for multiple raids to happen at the same time, even of opposing factions. Raiders will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. Human raiders flee if enough of them have been downed or killed, or if enough damage to your colony has been done. Mechanoids will persist indefinitely.

Arrival methods[edit]

Tribal-level factions can't use drop pods, so are limited to assaults.

  • Assaults: Arrive at the edge of the map, either by walking or by drop pod. They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.
  • Center drop: Raiders immediately attack via drop pod, centered on one of your colonists. There is 40% to drop on an unroofed orbital trade beacon if one is present. Drop pods can go through constructed and thin rock roofs, but not overhead mountain.
  • Scatter drop: Raiders immediately attack via drop pod, which have gone "haywire" and will disperse throughout the map.
Types[edit]
  • Smart: "Unusually clever" raiders will seek to enter your base while avoiding traps and turrets.
  • Sappers: Sappers will mine or destroy walls to create the shortest route to a colonist's bedroom. Groups of sappers are smaller in number than the other raid types.
  • Breachers: Appear with breach-type raiders, such as tribals with breach axes or termite mechanoids. Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.
  • Siege: See below.

Siege[edit]

Sieges are a special type of raid. They arrive in drop pods, along with supplies. They will construct sandbags and mortars, and will continuously be supplied with food and mortar shells. They will fire at colonists, colony structures, and other pawns they are hostile to. Sieges will directly assault the colony after a long time (a few days), if their mortars are destroyed or unbuildable, or after sufficient casualties.

It is possible to steal a critical material (like components) and prevent them from completing construction. This is largely possible with a psycasterContent added by the Royalty DLC using both Invisibility and Skip, with enough heat capacity to cast both 2-3 times in a row.

Strategies to force sieges to attack include the sniper rifle (watch out for other snipers), a psychic animal pulser, or your own mortars.

Infestation[edit]


Infestations come with hives and insectoids. Hives will produce insect jelly, but will rapidly create insects, too. If you don't want it to infest the whole area, muster your forces and destroy it. But beware - the bugs will defend their hive.

In order for a regular infestation to spawn, there must be an open area with the overhead mountain roof, within 30 tiles of a colony structure, and a temperature above -17 °C (1.4 °F). Light, and temperatures below -8 °C (17.6 °F) reduce the chance of infestations.

The Too Deep: Infestation is a separate event. Insects can still arrive, but this event has separate mechanics.

The Wastepack infestations is a separate event available if BiotechContent added by the Biotech DLC is active. The end effect is similar, but the mechanics are different.


Manhunter pack[edit]


A pack of scaria-infested animals have arrived, hunting for human flesh. A manhunter pack has 40% more points (i.e. 40% more "raiders") than a regular raid. When killed, scaria has a chance to instantly rot a corpse, which makes them inedible and creates rot stink. A single animal can arrive and the event will still be called a "pack".

Manhunters will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. If left alive, they will congregate around your base for anywhere from 24 to 54 in-game hours before they all leave.

Manhunting wargs

Psychic wave[edit]


Appears as Mad Animals: (Animal name). Immediately drives local wildlife insane, becoming manhunter. As opposed to a manhunter pack, these animals do not have scaria, and so won't immediately rot. No new animals are created - only animals already on the map can be affected. This fact means that psychic waves scale poorly with raid points; advanced colonies will find these events much smaller than any other major threat.

As manhunters, the selected animals will roam the region, attacking any human they can path to. The animals can't enter doors, but if they see a colonist run behind a door, they will attempt to beat down the door. Unlike with scaria, the manhunter status will end when the animals need to sleep.

This event has a variation that only affects a single animal, which is not considered a major threat.

Crashed ship part[edit]


A large piece of an ancient ship crashes nearby, along with a pack of mechanoids. The mechs will generate dormant, but will awaken when they or the ship part are attacked. While the ship part is still active, they will activate an intensifying negative effect on the map.

Defoliator ship[edit]

A crashed defoliator ship kills all wild or domesticated plants in an expanding circle, up to a radius of 100 tiles. The poison kills crops randomly, including plants grown in hydroponics basins. Crops will end up nearly impossible to grow. If the Biotech DLC is active, this ship part will also generate PollutionContent added by the Biotech DLC from its center at a rate of 6~7 tiles per day.

Psychic ship[edit]

A ship part projects a psychic drone which negatively affects the mood of a specific gender. It begins low and grows progressively stronger the longer it stays. Psychic sensitivity increases or decreases the drone's effect.

The ship's is also capable of emitting psychic pulses that can drive a colonist to an immediate mental break, or nearby animals to madness.

Drone intensifies[edit]

If left alone long enough, the drone emitted from a crashed psychic ship will get worse as time goes on. Every 2.5 days the drone gets stronger, from -12 mood at the beginning up to -48 after 7.5 days.

Mech cluster[edit]


Mech clusters are similar to crashed ship parts with a more complex structure, with buildings like walls, turrets, and unstable power cells. They also spawn dormant, but can come with activators, able to wake up from proximity or over time. They can come with on-map condition causers, such as sun blockers or EMP dynamos.

Problem causer[edit]


A condition causer has appeared within 10 world tiles of your colony, creating a negative effect. It must be destroyed to stop the effect. Some conditions may be situationally good, such as a psychic suppressor (male) when you only have females in the colony.


Extreme weather[edit]

These events alter the environmental conditions of the colony map, only able to appear from Base Builder difficulty onward.

Show/Hide Extreme Weather Events

Flashstorm[edit]


FlashstormScreenshot.png

"A freak localized storm is blasting a small area with repeated lightning strikes."

Flashstorm is a localized, intense lightning storm within a radius between 45 and 60 tiles. Active lightning will strike between every 320 ticks (5.33 secs) to 800 ticks (13.33 secs). Once it finishes, no rain can fall until 30,000 ticks (8.33 mins) has passed. This can create big fires. It lasts between 0.075 and 0.1 days, and will not reoccur for 15 days. Clicking the envelope icon offers the option to jump to the center point.

This can also be caused by the Flashstorm Psycast Content added by the Royalty DLC, but will not show up as a notification.

Toxic fallout[edit]


"A distant chemical fire has released a plume of poison over this entire region that will slowly settle out of the atmosphere. It will last for anywhere from a few days to an entire season."

Toxic fallout is a dangerous event which causes toxic buildup to any pawn not under a roof. The fallout also gives a −5 moodlet for colonists when outside. It lasts between 2.5 and 10.5 days, will not occur before Day 60 of the colony, and will not reoccur for 90 days.

Toxic buildup from toxic fallout is proportional to both Toxic Resistance and the Toxic Environment Resistance of the pawn. Animals have 50% Toxic Resistance, so buildup increases at half the rate, but exposed animals will eventually die. When animals die with toxic buildup, there is a chance, scaling with severity, for their corpse to immediately rot.

By default, toxic buildup increases at a rate of 40% per day. For humans, a moderate buildup - 40% severity, or 24 hours left outside - is enough to potentially cause permanent damage, from either dementia or carcinoma. Death happens at 100% severity. In Biotech,Content added by the Biotech DLC both resistances can be gained in a number of ways, allowing counters to the effects of the fallout. These include the face mask, gas mask, detoxifier kidney, detoxifier lung and several genes.

Excluding some special cases (Anima treeContent added by the Royalty DLC, Anima grassContent added by the Royalty DLC, Gauranlen treeContent added by the Ideology DLC, Gauranlen podContent added by the Ideology DLC, Polux treeContent added by the Biotech DLC), all plants will wither during the fallout, trees included. Every in-game hour, the affected plants will receive between 48.9 and 66.1 points of damage [57.51667 base damage ±15%]. Crops can be protected under a roof, but without a sun lamp, they'll rot anyways. Insectoids and mechanoids are fully immune.

Volcanic winter[edit]


"A distant supervolcano has erupted and begun spewing millions of cubic kilometers of ash into the atmosphere. Ash in the atmosphere will obscure the sun. Temperatures will drop and plants will suffer for lack of sunlight. It could pass in a few weeks, or it might last many months."

Volcanic winter lowers the temperature and natural light, which in turn weakens solar generators and slows plant growth. They also appear to significantly reduce the inflow of wildlife (observed in a Temperate Forest, 300x300, very few animals came in during Spring-Summer when there would normally be many). This can easily lead to meat shortage and famine if you do not have sufficiently large farms for your colony. Volcanic winters will last between 7.5 and 40 days, will not occur before Day 60 of the colony, and will not reoccur for 140 days.

To be specific, the temperature is reduced by 7 °C (44.6 °F) and the light by 30% over the course of 50,000 ticks (13.89 mins). The wildlife density is cut by half, and pawns can no longer enjoy their time outside.


Random Events[edit]

These are the 3rd set of events able to be triggered by the storyteller. Internally, Random Events are classified as either good, bad, or quest.

Quests[edit]

Quests are a class of event that provide conditions to be met or actions to be performed to gain a reward. There are a wide variety of quests, which are listed on the quest page.

Good[edit]

Show Good Random Events

Ambrosia sprout[edit]

An ambrosia sprout among the trees
Ambrosia bush.png

A grove of the mysterious ambrosia bush has sprouted nearby! If you wait for the plants to grow, you'll be able to harvest the delicious, pleasurable, and slightly addictive fruit.

Ambrosia bushes are the only way to harvest ambrosia, a safe mood boosting social drug. A good way to harvest them is to draw a growing zone over them, but forbid sowing. Colonists will then automatically harvest the bushes when they are fully grown.

It can only happen in the following biomes:

Animals join[edit]

Tamed dogs or farm animals from off-map join your colony.

Animal self-tamed[edit]

Thrumbo self-tamed.png

A random animal on the map becomes tame, and immediately joins the colony. The frequency of self-taming events is unrelated to the number of animals on the map, provided there is at least one. This means in a tundra biome with one snowhare you're just as likely to get a self-taming event as in a tropical swamp populated with dozens of animals. Previously tamed animals can self-tame, and will retain the name and all training they previously had.

For pen animals, you must rope them into a pen or to a caravan hitching spot or the animal will eventually run off the map, though usually this is not urgent. For zoneable animals, you should check the "Animals" tab and assign the animal to an appropriate zone, unless you want to let it move unrestricted. If you are dangerously low on food, be aware that if a zoneable animal self-tames and there is no food in the environment, it will run inside your base and eat your food stores when it gets hungry.

Aurora[edit]

An aurora lights up the night sky, giving a +14 mood boost to anyone who is outside watching. While in real life it only happens near the poles, on the rimworlds it can happen anywhere regardless of latitude. It ends at day and otherwise lasts from 0.125 to 0.35 days.

Despite the event text stating that it will "make the night brighter", it does not actually affect the light level.

Cargo pods[edit]

Cargo pods.png

From time to time, cargo pods will fall out of orbit, containing a random amount of single type of resource. The remains of the pods become steel slag chunks, which can be refined into usable metal at an electric smelter. The pods have a chance of crashing through the roofs of any buildings, damaging any nearby furniture, structures or any pawn they land on.

Herd migration: (Animal)[edit]

Thrumbo herd migration.png

A large herd of animals is passing through the area. They won't attack unless provoked. They pass by quickly, so you must be quick if you want to hunt or attempt taming them.

This event only occurs in the following biomes:

Party[edit]

One of your colonists will throw a party around a party spot, or if unavailable, a gather spot (table or campfire). Colonists will continually get mood buffs the longer they attend a party.[Detail] Each stack adds +0.8 to mood, lasts 10 days and stacks up to 10 times, for a max buff of +8 mood. In addition, a party provides many social opportunities. They will usually have beers and smokeleaf joints, if available, and eat meals even when not hungry.

Pawns that don't attend won't get mood buffs. Players may have to draft and undraft pawns to get them out of work. If too many pawns, or the hosting pawn are drafted at once, or if a raid happens, then the party will be called off.

Psychic soothe[edit]

Psychic soothe.png

When this event triggers, the soothe gives a positive mood modifier (+16 for normal colonists, more or less depending on the Psychic Sensitivity) to all colonists of a randomly chosen sex. It can be considered the opposite of the Psychic Drone, but does not have different levels of severity. It lasts between 1.5 and 3.0 days and will not reoccur for 15 days.

(Trader type)[edit]

This event, without a faction mentioned, occurs when an orbital trade ship passes near the colony and you have a powered comms console. Players may trade to obtain resources or weapons, or alternatively sell excess items for silver, which is always accepted by traders. Note that orbital trade ships can appear even when the comms console is turned off, so check the console during a solar flare.

You need to build orbital trade beacons before contacting them so you can beam silver and items up to the ship to actually carry out transactions. You can still check the items for sale even without them however.

(Trader type) from (Faction)[edit]

This event with the faction name mentioned means the traders are terrestrial. Trader caravans from other non-hostile factions can stop by your colony, whether specifically requested via the comms console at a hit to good will or randomly on their own with no penalty.

Transport pod crash[edit]

Since you rescued him/her. Character joined your group!

A downed and injured occupant falls from the sky, containing members of a faction or neutral, unaffiliated spacers. A friendly or neutral occupant can be rescued to a medical bed, while a hostile member must be put into a prison bed. The pawn can also be a xenotypeContent added by the Biotech DLC that doesn't have any factions on the planet.[Detail needed]

Once healed, non-hostile crash victims will either join your colony out of gratitude, or walk away to return to their faction. You can instead capture a non-hostile person, but their faction (if not spacer) will turn hostile.

Paralytic abasia[edit]

A transport pod can crash with a person with paralytic abasia, a disease which prevents movement until cured (usually after 40 days). Unlike regular transport pods, the person will directly ask to join the colony. If you refuse, then colonists will get the same penalties as if you banished another colonist.

Baby[edit]

A transport pod may crash with a baby instead of the regular occupant, and will always appear as a friendly faction/neutral refugee/unaffiliated. You can choose to ignore it and let it starve to death, or adopt the baby by selecting it and click "Adopt". Rarely, the corpse of the baby's parent can also appear next to it, still in pristine condition.

Wanderer joins[edit]

A random person will forcefully try and join the colony. You have 24 hours to accept or reject them. Accepting will have them appear on the world map. Rejecting will give the same penalties as if you had banished a colonist. Unless it'd be dangerous to enter your colony, there is no reason not to accept the wanderer, see their stats, and then decide to keep or banish them.

With IdeologyContent added by the Ideology DLC, the colonist that joins the colony will have a randomized Ideoligion. This event can also occur at 50% rate if an Ideoligion's event result set for this event is "Beautiful/Fun/Good / Unforgettable", with said colonist with the same Ideoligion as the masses of the colonist in the colony.

Wild (wo)man wanders in[edit]

A random person with no faction wanders into your colony and will mill about the map. You have the option to Tame this person with a minimum Animals skill of 7. Doing so will convert them to into a completely normal colonist. Sometimes, they may not be able to resist the harshness of nature and may fall unconscious (ex: Toxic Fallout, extreme temperatures), allowing you to rescue them like transport pod crash victims. They also have the same hunger needs as regular humans, and if they do not find animals to hunt or wild plants (or simply do not want to) they can walk into your base and eat your food, which can be an annoyance. Arresting them will not allow you to recruit or enslaveContent added by the Ideology DLC them like regular prisoners, they must be tamed or rescued.

Wild humans have a 50% chance of attacking when harmed, and 10% if taming fails.

These wild (wo)men may have random Ideoligion with Ideology.

Unlike other animals, wild people will not flee from gunfire. Wild people can hunt human pawns for food like a predator, regardless of whether they are cannibals or not. Wild people who are incapable of violence will not hunt at all, but may still become manhunter when provoked.

Traveler Visit[edit]

Occasionally, one or more members of a friendly faction will arrive, just passing through. They'll enter at one edge of the map and proceed across the map. They'll exit the map upon reaching another edge.

A drafted colonist can be directed to capture (arrest) one of the travelers. However, once the arresting colonist reaches the target, that entire faction will immediately turn extremely hostile, dropping to -76 Goodwill. This shift includes any other members of the same Faction currently there.


Visitor(s)[edit]

Friendly faction members may stop by your settlement. Occasionally, they will have a few goods to trade. Like a regular trader they will mill about the player's colony for a while. Unlike a regular trader, they don't have many goods with them, nor do they have as much silver to buy your goods. Visitors possess no higher purpose otherwise, but will fight mutual enemies.

Sometimes there will be a singular visitor. In this case, the game will notify you of the backstory of that visitor.

Royal Tribute Collector[edit]

If you are not hostile to the Empire, Royal Tribute Collectors will visit the colony approximately twice a year. Tribute collectors are essentially Empire-only trade caravans that exclusively accept gold and prisoners in exchange for Honor.

Gauranlen pod sprout[edit]

A Gauranlen pod has sprouted nearby! Harvest it to collect a Gauranlen seed. This special seed can be used to plant the majestic Gauranlen tree. Your colonist can connect with Guaranlen trees and make them spawn resources and helpful dryads to work or fight for you.

A pod will appear somewhere with the current map. Harvesting it yield 1-2 Gauranlen seed. This event occurs roughly every 60 days in every biome except Ice Sheets and Sea Ice, and this time is decreased to roughly every 30 days for tree connectors. This event can also occur if an Ideoligion's ritual result is set to trigger this event and performing the ritual receives a "Beautiful/Fun/Good/Unforgettable" quality.

Polux tree sprout[edit]

A polux tree may appear whenever there is enough pollution around. It will consume and clean up said pollution, but will not do so if it or its roots are under a roof.

Bad[edit]

Show Bad Random Events

Beavers![edit]

A group of ravenous tree-munching alphabeavers appears at the edge of the map. This only occurs in the arid shrubland and tundra, and only when the outdoor temperature is above the alphabeaver's minimum comfortable temperature of -40 °C (-40 °F). It will not reoccur for 30 days.

Beavers will act like any other animal. But due to their unique diet and extreme hunger, beavers will continually eat trees and Saguaro cacti they can reach, including anima treesContent added by the Royalty DLC, gauranlen treesContent added by the Ideology DLC, polux treesContent added by the Biotech DLC and any trees you're farming. Alphabeavers will not and cannot eat the Wood wood item, wooden buildings, or any other item made out of wood.

The beavers will continue eating until there are no trees left, unless you eradicate them or they're driven off the map by temperature.

Birthday[edit]

Character gains an age-related illness, such as bad back or cataracts. They may be cured by using the healer mech serum, luciferium, a biosculpter podContent added by the Ideology DLC, or the Scarless geneContent added by the Biotech DLC. Some may be 'cured' by replacing the affected parts with bionics.

Due to age or a pre-existing health condition, they can also have a heart attack.

Blight[edit]

Blighted crops with an indicator above them.

Blight is a disease that infects domesticated plants with a growing period shorter than 15 days. Blighted crops will not grow or yield anything when harvested, and the blight will spread to other nearby plants within 3 tiles. These plants must be cut in order to avoid further spread. Trees, wild, decorative plants, and devilstrand mushrooms are immune to blight.

Blight starts on one of your crops, at 10% severity, affecting 20% of your plants (40% initial plants affected has been witnessed in December 2020). It will progress slowly once plants are infected, and once it reaches 28% it can spread to nearby plants within a 4-tile radius.

It will not reoccur for 30 days.

Disease[edit]

Colonists (including prisoners and slavesContent added by the Ideology DLC) or animals will gain a random disease. Biome influences both the amount of disease and its selection. Multiple pawns can get a disease at once, but diseases never spread between pawns. Disease events are controlled separately from other events by your storyteller.

Sickly pawns will get sick with a MTB of 30 days, independently of the rest of your colonists.

Eclipse[edit]

A moon has moved in front of the sun, causing an eclipse. Without light, solar generators won't function, and outdoor crops stop growing. It lasts between 0.75 and 1.25 days.

If reliant on solar power, make sure to have batteries for times like these, or an eclipse raid can be extra threatening.

Pawns with the Eclipse: Beautiful preceptContent added by the Ideology DLC will receive a +5 moodlet for seeing an eclipse.

It will not reoccur for 15 days

Heat wave[edit]

A heat wave sweeps the colony, driving outdoor temperatures unusually high for 1.5 and 3.5 days. To be precise, the temperature will increase by 17 °C (62.6 °F) over 12000 game ticks (4.8 in-game hours). There is also a chance for a fire to randomly appear on the map, which can quickly spread. It only occurs when the map's summer temperature is at least 20 °C (68 °F), and will not reoccur for 30 days.

The major risks are coolers failing to freeze food, and heat stroke to your colonists and animals. Summer clothing like cowboy hats and tribalwear can mitigate the heat, and passive coolers can help make indoor temperatures bearable.

Do note that an while this event remains active, the colony will not trigger the events Cold Snaps, Volcanic Winter, nor additional Heat Waves. The one exception are events triggered by quest, which will apply regardless.

Cold snap[edit]

A cold snap strikes the colony, driving outdoor temperature unusually low for 1.5 and 3.5 days. To be precise, the temperature decreases by 20 °C (68 °F) over 12000 game ticks (4.8 in-game hours). It only occurs when the map's summer temperature is in the range of 0 °C – 15 °C (32 °F – 59 °F), and will not reoccur for 30 days. Colonists will complain about the cold, especially sleeping in it if their rooms are not properly heated.

While this is generally good for item preservation, it can kill off crops, influence colonist moods and cause hypothermia if colonists or animals stay in non-heated areas for a prolonged time. It also renders most of the plants in the area inedible (unless when it happens in warmer areas in which some plants are still edible), potentially causing tame animals to starve to death and wild ones to leave the map. With no other food source, wild predators may attack colonists and tame animals while they are outdoors. Snowing may also happen, depositing thick snow that can slow down outdoor movement significantly.

Jackets, dusters, parkas and tuques provide cold insulation for colonists, protecting them while they're awake, though they don't prevent mood loss caused by sleeping in cold areas.

Do note that an while this event remains active, the colony will not trigger the events Heat Waves, Volcanic Winter, nor additional Cold Snaps. The one exception are events triggered by quest, which will apply regardless.


Mad animal[edit]

A single random animal on the map turns manhunter, like a psychic wave. The insane animal will charge toward the nearest human anywhere on the map, attacking any other animal or obstacle (doors, fences, barricades, etc.) blocking its way. If the "nearest" colonist changes, the animal may change its focus to that target.

Any animal can be dangerous to a colonist, but multiple colonists can usually take them out. Large animals, as well as the explosive boomalope and boomrat, are bigger threats.

Psychic drone[edit]

'Drone' in this case does not refer to "Unmanned Aerial Vehicle" but instead "To produce a low-pitched hum or buzz." A psychic drone affects all colonists of a randomly chosen gender, giving a strong negative moodlet. The drone can vary in severity, from low (-12 mood) to extreme (-40 mood). Psychic Sensitivity will multiply the effect on the drone. It lasts between 0.75 and 1.75 days and will not reoccur for 15 days.

Colonists have no choice but to endure it, as the point of origin is off-map. Psychic foil helmets, drugs, and other mood-enhancers can help deal with the effects. Animals are not affected.

Solar flare[edit]

Solar flares cause all electrical devices to stop working for its duration, from 0.15 to 0.5 days. Wood-fired generators and chemfuel generators will still burn fuel during this time.

  • Colonies that rely on turrets for defense will become vulnerable to raids.
  • Heaters and coolers will stop working. In extreme temperatures, crops will die and colonists can be at risk of heatstroke or hypothermia. Campfires and passive coolers are low-tech options that work even in a solar flare.
  • Crops in a hydroponics basin will rapidly degrade, regardless of the temperature. It's recommended to quickly harvest any crops that can't be saved before they die.
  • Occasionally an orbital trade ship may arrive during the event, so it is wise to check out the Comms Console as soon as the event ends or risk getting the ''<trader> has left comms range" notification while unaware of their presence. If a ship leaves during a solar flare, you will be notified that the trader has left, although this is only a minor message in the upper right of the screen.
  • The colony is immune to the effects of a solar flare while also undergoing unnatural darknessContent added by the Anomaly DLC

Due to its length, most of the adverse effects are manageable.

Zzztt[edit]

This event can occur anytime a power conduit has energy flowing through it. The conduit may suffer a fault, causing a short circuit. They may also occur if certain objects are left unroofed and are exposed to rain or snow. Short-circuits not caused by rain/snow will not reoccur for 8 days. Short circuits do not affect hidden conduits, meaning zzztts can be avoided entirely by simply having all applicable buildings under roofs and having a network made entirely of hidden conduits.

The following buildings short circuit due to weather:

Short circuits will either result in a fire, or, if any batteries are connected to the circuit and contains at least 20Wd, a fiery explosion centered on the tile, that increases with energy stored. The explosion deals 10 Flame damage and setting objects on fire. If the explosion radius is greater than 3.5 tiles, a second explosion of 30% radius deals 50 Bomb damage, which can extinguish fires. The fault will also discharge all stored power in batteries in the process.

The explosion radius is controlled by the following equation:

Explosion Radius = clamp( sqrt(Sum of all stored power) * 0.05, 1.5, 14.9)

Or in other words, the radius will be at least 1.5 tiles, and at most 14.9 tiles, with a bomb explosion of 4.5 tiles. This occurs when a total of 90,000 Wd is stored. Bomb explosions can occur beyond once 4,900 Wd are stored.

Explosion radii per number of batteries filled

Unconnected batteries, such as through an open switch or on separate power network, will not be affected. Power networks which contain only batteries and no conduits will not experience this event. Power networks which contain only conduits will only have a single tile on fire, as there's no stored power to be discharged.

Transport pod crash (Ghoul)[edit]

A transport pod may crash with a ghoul instead of the regular occupant, and will always appear as unaffiliated. They will always appear as hostile and will initially be in shock, but if left ignored, will immediately attempt to attack anything or anyone nearby after a while.

Gray pall[edit]

A fog of eerie, gritty dust settles on the map. Colonists standing in an unroofed area will receive a −6 gray pall exposure moodlet, while colonists under a roof will have −3 gray pall. The pall is otherwise not dangerous and disappears after 1-2 days.


Incidental Events[edit]

These events aren't triggered by the storyteller. Instead, they come from various other game mechanics. For purposes of the wiki, these are divided in good, bad, faction, informational, and social events.

World incidents[edit]

These are events related to/only triggered on the overworld.

Show/Hide World Events

Attack begun[edit]

This notification will appear when a caravan has arrived at a settlement chosen for attacking.

Bandit camp opportunity[edit]

Some ruffians are causing trouble nearby and other factions will pay you to wipe them out.

The bandit camp will time out and are weaker than regular enemy bases.

Destroying them increases goodwill by 8 and returns a payment worth 2000 to 3000 worth of silver, whether it consists of items or silver itself.

Caravan ambushed / (manhunters)[edit]

While traveling, one of your caravans are attacked. The game will give you a mini map to defend it.

The attackers can be an enemy faction lying in ambush or a rampaging manhunter pack your caravan unfortunately trespasses upon.

Caravan battle won[edit]

This event will tell you if your people won their fight, and can reform the caravan on the world map.

Caravan arrived at (Location)[edit]

This is a simple notification that your caravan has arrived at their destination.

Caravan lost[edit]

Caravan destroyed.png

All human members of your caravan have died, or have been downed on an event map. Anything carried by the caravan, including animals, will be lost to the wild.

If colonists were downed but not killed while fighting human enemies, it is possible for some of them to appear later in a Prisoner Rescue Quest.

Caravan meeting by (Caravan ID)[edit]

This is a pop up window rather than an event with envelope icon. While away from your bases, your caravans may randomly encounter other traders out in the world who would be happy to trade with you. Of course, you also have the option to attack them. Be careful, trade caravans are usually well defended.

Caravan ready[edit]

Once you've designated a caravan, you'll get this notification once all of the colonists, prisoners, animals and items have been assembled and left the map. It is now ready to send to other settlements or form another settlement of your own, if you've enabled multiple settlements in the game's settings.

Demand[edit]

A hostile faction approaches your caravan and demand that you give them items and/or hand over members as slaves. If you refuse, they will proceed to assault the caravan.

You can see their number when they are demanding you hand over items.

Peace talks[edit]

Peace talks.png

A hostile faction leader decides to drop his weapons and offers to talk things out for once. The offer expires after 15 days if ignored. Pirates will never attempt peace talks.

To participate, you will need to send a caravan with a capable negotiator. Once the destination is reached, the most capable negotiator in your caravan will proceed to talk with the leader to hopefully improve relations.

There are several outcomes of the incident, each being a sub-event of its own. No matter the outcome, your negotiator will always gain social skill.

Result Description Base Weight
Peace talk triumph The peace talks were very successful, giving a great boost to relations from 50 to 75. In addition, the faction will give a farewell gift worth between 500 and 1500 silver.
Despite your triumph, if you don't manage to bring relations above 0, they will still remain hostile.
0.1
Peace talk success The talks were a success, and relations between the factions have warmed somewhat, from 25 to 75. 0.55
Peace talk flounder The talks were neither successful nor a failure, and relations remain unchanged. 0.2
Peace talk backfire The peace talks backfired, and relations have gotten worse than they started, from -10 to -50 relations. 0.1
Peace talk disaster The peace talks have failed so miserably that the faction hates you a lot more now, with a -25 to -75 damage to relations, as well as instantly turning hostile if they aren't already. In addition, the angered faction sends a group of attackers after your negotiating party. 0.05
Outcome chances[edit]

The actual outcome chances are dependent on the negotiator's Diplomacy Power stat, after going through a simple curve. To do this, the game calculates the bad outcome factor, of the negotiator first.

  • At 0% power, the bad outcome factor is 4.
  • At 100% power (healthy, lvl 10 Social), the bad outcome factor is 1.
  • At 150% power (healthy, lvl 20 Social), the bad outcome factor is 0.4.

The new weight of each outcome is calculated afterwards.

  • Triumph = 0.1 * ( 1 / Bad Outcome Factor)
  • Success = 0.55 * ( 1 / Bad Outcome Factor)
  • Flounder = 0.2
  • Backfire = 0.1 * Bad Outcome Factor
  • Disaster = 0.05 * Bad Outcome Factor

The sum total of the new weights is then calculated.

Finally, the probability of each outcome is calculated:

Probability of each outcome = New Weight ÷ Sum Total of Weights


Example

Take a level 15 Social negotiator as an example:

  1. The diplomacy power is 125%, corresponding to a bad outcome factor of 0.7.
  2. The new weight of each outcome, to 3 d.p.:
    • Triumph = 0.1 * ( 1 / 0.7) = 0.143
    • Success = 0.55 * ( 1 / 0.7) = 0.786
    • Flounder = 0.2
    • Backfire = 0.1 * 0.7 = 0.07
    • Disaster = 0.05 * 0.7 = 0.035
  3. The sum total of new weights is calculated:
    • 0.143 + 0.786 + 0.2 + 0.07 + 0.035 = 1.234
  4. Finally, the probability of each event, to 2 d.p.:
    • Triumph = 0.143 / 1.234 = 11.58%
    • Success = 0.786 / 1.234 = 63.69%
    • Flounder = 0.2 / 1.234 = 16.21%
    • Backfire = 0.07 / 1.234 = 5.67%
    • Disaster = 0.035 / 1.234 = 2.84%

Rescuee joins[edit]

Should you succeed in rescuing a prisoner or you offer help to an incapacitated refugee, he or she will immediately join your faction.

Sub-events[edit]

These aren't quest events on its own, but may happen during other world events such as Incapacitated Refugee or Item Stash Opportunity.

Ambush[edit]

Incapacitated refugee Ambushed.png

Enemies may enter the minimap a little while after your colonists arrive or suddenly appear near the objective when your pawns draw close to it. It's even possible for animals to lie in wait.

Sleeping mechanoids[edit]

When the map generates, sleeping mechanoids will be present near the objective. Going too close to them will awaken them, making them attack. While they are present, you cannot manually reform the caravan as the game notifies you that there are hostiles in the area, but you can still leave through the edges.

Game endings[edit]

When these happen, they signify that your game has ended, one way or another.

Game over[edit]

Welp, time to start a new game I guess...

This happens when all your colonists are either dead, missing, or left the planet. The game will show a Letter which says that everyone is gone or dead, and allows you to return to the main menu. You can continue playing, and someone may find a use for the wreckage of your base.

Should you decide to continue playing, events will continue to happen, which can affect the ruined base but not anyone. You can strike lucky and roll 'Wanderer joins' or 'Refugee chased' events, giving you a colonist to rebuild from.

Post 1.4, the game over letter has been updated with the option to generate multiple new colonists as a whole group. This event is referred to in the scenario editor as the Wanderers (plural) Join incident, although it always occurs, only manually. This works just the same as the beginning colonist selection, including specifying age range and xenotypes and sharing your original ideology.

Planetkiller[edit]

Ouch.

"An interstellar planetkiller weapon is approaching this planet. It will smash the planet apart like a rifle bullet hitting an egg, annihilating all life."

This event can only happen by configuring the starting scenario.

When it happens, the screen will fade to white, and a message will show that the planet is obliterated by a planetkiller and that you did not survive.

Unlike your regular 'Game Over', you cannot continue the game. Saved games (including permadeath) can be continued from their last saves, however.

Ending - The Archonexus Core[edit]

For specifics, see Endings#The_Archonexus.

Once it happens, your colony is succesfully noticed by an archotech. What happens next is left to especulation.

Similar to the Planetkiller and unlike other endings, you cannot continue the game once reaching this ending. Saved games (including permadeath) can be continued from their last saves, however.


Legacy events[edit]

Events from previous versions of RimWorld, now removed.

Bonded animal's death[edit]

Bonded animal dies affecting the owner's mood.

Both of these bonded death events were simplified into the Death: (Pawn) event.

An animal with a bond to a colonist dies, affecting that colonist's mood negatively. Enemies may directly target your animals during attacks. Enemies, turrets or even your own colonists can even hit them unintentionally during shootouts, especially animals trained for Release and checked to follow your drafted colonists in the Animals tab. Wild predators may hunt and kill your animals, including bonded ones. Bonded animals can also fall into traps. It can even occur intentionally by slaughtering, euthanizing or manually drafting and attacking the bonded animal.

Bonded master's death[edit]

Both of these bonded death events were simplified into the Death: (Pawn) event.

The inverse of a bonded animal's death. This time, it's the master who dies, through causes such as enemy raids, disease or large wild predators getting hungry.

When this happens, any animal that is bonded to the master will have a mental break. It can be a less dangerous one such as a dazed wander, or a more dangerous one such as a berserk rage.

This is one of the only situations where animals can have non-manhunter mental breaks.

Breakdown: (Machine)[edit]

In previous versions, this was its own event. Now it's just a notification.

One of your machines will break down and will not work until repaired with a component. If this happens to a hydroponics basin, any crops in it will wither and die unless repaired immediately.

This only applies to machines using electricity.

Tornado[edit]

A tornado has touched down in this region, and will proceed to wreak havoc on anything in its way. There is small chance it may spawn at the map borders and eventually leave the map.

Tornadoes rapidly deal damage to any structure or item that is right beneath it. Any pawn underneath will rapidly receive scratches from the random objects blowing about in the wind.

Naturally forming tornadoes are exclusive to Beta 18. You can still use the Tornado generator to spawn them in for defense purposes.

Event data[edit]

Note: events that give colonists, such as wanderers or transport pod crashes, are affected by the storyteller's population intent factor. They become more common if you have few colonists, and rare if you have many.
