Random events
Tomb World colony events have large chance to trigger 2 or 3 years after a Tomb World has been colonized. Each event can only happen once per empire. Unlike most other colony events, tomb world colony events can still happen if the planet has already had a different colony event. All tomb world colony events are equally likely to trigger.
Generic tomb world colony event triggers[]
The following conditions are must be true for all Tomb World colony events:
- Planet owner
Planet is owned by the original owner- Planet owner is not AI
- Planet
- Planet is a Tomb World
- Planet wasn't made into a Tomb World by orbital bombardment
- Planet isn't a species homeworld
- Neither this planet nor any other planet in the same solar system is an empire's capital
- Planet doesn't have ground combat and isn't occupied
- Colony has at least one Pop

Ruined Particle Accelerator
We have discovered what appears to be the remains of a massive particle accelerator on [colony name]. It was found in a still-radioactive region covered in massive bomb craters, suggesting the accelerator was considered a strategic target of great importance during the [planet or moon]'s nuclear war.
We have recovered several research logs written by the scientist in charge of the accelerator. Although the technology of her civilization was fairly primitive, some of the theoretical research and formulas described in the logs are advanced even by our standards. Our physicists are poring over the data now.

Surviving Infrastructure
Infrastructure that survived the great nuclear war which ruined [colony name] have proved a great boon to our colonists. The alien civilization that once lived here built highways connecting their major population centers, and some of them are still in good enough condition to be used today.
We have also been able to recycle a large amount of building material from the many ruins that dot the landscape, further improving our colony's infrastructure.

Derelict Space Station
A small team from our colony on [colony name] recently boarded a primitive space station that had been left in orbit by the [planet or moon]'s original inhabitants. The mummified remains of the station's crew could still be found clustered around viewports facing the [planet or moon]. They must have realized they were doomed after seeing the billowing mushroom clouds below, and communication logs shows that the astronauts made several futile and increasingly frantic attempts to contact the surface before they eventually ran out of supplies.
The station is in good condition, and it has afforded our engineers a rare glimpse of the early stages of a planetary space program. They have gained several ideas from the primitive yet ingenious solutions used in the station's design.

Wasteland Radiation
The radiation levels in some wasteland regions of [colony name] appear to be greater than our previous scans had indicated. Colonists in several local settlements have complained of poor health, and birth rates are down. We are taking steps to evacuate the affected regions, but these measures will take time.

Unfortunate.

Pacifist Movement
The decrepit ruins and desolate wastelands found on [colony name] seem to have prompted many of the [planet or moon]'s colonists to adopt some kind of pacifistic philosophy.
Members of this new movement claim that the environment they live in serve as a daily reminder of the senseless horrors of war. They see it as their civic duty to prevent the terrible destruction visited upon [colony name] from occurring on other worlds.

   These wretched cowards shame our nation!
  Excellent. Everyone should give peace a chance.

Nuclear Bomb
While exploring some ruins near one of our major settlements on [Root.GetName], a few colonists inadvertently activated the timer on an undetonated hydrogen bomb left over from the [Root.GetPlanetMoon]'s previous nuclear war.
| |||||||||
Special Project Completed
We have successfully disarmed the hydrogen bomb on [From.From.GetName]! It has been safely disposed of and specialist teams are now scouring the [From.From.GetPlanetMoon]'s surface of any other undetonated munitions. This will hopefully reduce the chances of another incident like this occurring.
|
Special Project Failed
 Our bomb disposal team failed to defuse the hydrogen bomb on [From.From.GetName] in time. They, along with every other living thing within a 100 kilometer radius, were eradicated when the bomb detonated. Untold lives have been lost, the last victims of a tragic and pointless war that began millennia ago.

Orbital Debris
The orbital space around [Root.GetName] is cluttered with debris left behind by the alien civilization that once inhabited the [Root.GetPlanetMoon]. Before they wiped themselves out, their early space programs saw the launch of thousands of primitive satellites and missile launch platforms. Many of these were destroyed by anti-satellite weapons during the [Root.GetPlanetMoon]'s destructive nuclear war, adding even more space junk to the mix.
| |||||||||
Freighter Crash
 A civilian freighter coming in to land on [Root.GetName] was perforated by a dense cloud of fast-moving orbital debris! The flight crew was killed immediately, and the stricken craft tumbled through the atmosphere only to crash-land near one of the colony's main power relays. The resulting explosion resulted in several deaths on the ground, and local infrastructure suffered considerable damage.
|
Debris Impact
A cascade of collisions in the dense layer of debris surrounding [Root.GetName] recently shifted the orbit of a large piece of space junk. The object - which we believe was one of the many orbital missile platforms used in the [Root.GetPlanetMoon]'s nuclear war - was pulled into the atmosphere, and unfortunately proceeded to impact directly on top of a major settlement. Initial reports indicate heavy casualties.

 With the assistance of our Science Ship, colonial authorities on [From.From.GetName] have finished cleaning up the [From.From.GetPlanetMoon]'s orbital space. It has now been made safe for satellites and civilian travel.
