## Introduction

**TRAPPIST-1** is the first story campaign in TerraGenesis, with the second one being the Historical Earths campaign. The planets need to be completed in a certain order. Huanca (TRAPPIST-1d) is the first planet needed to be colonized, and the last planet to be colonized is Ostara (TRAPPIST-1g).

This campaign is for sale for $6.99, or one can get all of them in the All-Access Pass for around $20.

## Gameplay - Spoiler Alert!

Six of these worlds hide a secret, malfunctioning alien artifact that affects the status of the world. Sometimes they will help the player, but most of the time, they are ruining the world. One destroys buildings (Dvintek), another increases pressure and reduces oxygen (Qelsetk), the third increases or reduces sea levels (Kivuunal), the fourth kills people (Metuurein), and the fifth wipes out research (Vuuresal). All those threats combine into one big threat when attempting to colonize Ostara.

A list of artifact firing events can be found here: *event specific to the world*

After colonizing each world, you can use the artifact that hindered the colonization of that planet on the next TRAPPIST-1 planets you colonize. going to the "SATELLITE" tab. On there, you can see the Tresuunak and all the artifacts that are installed on it. The player can activate them from there. Each time they use one of them, they to wait 30-minute cooldown times after firing.

On all TRAPPIST-1 worlds, except Huanca, one can access satellites before building spaceports because one already possess a spaceship, the Tresuunak. This is unique to TRAPPIST-1.

## Trivia

* TRAPPIST-1 is 39.46 light-years from Earth, and it has seven planets orbiting it.
* The TRAPPIST-1 system was discovered in 2017.
* TRAPPIST-1 is almost 9% of the sun's mass, with a radius slightly bigger than Jupiter.
* TRAPPIST-1 is one of the coldest known stars, with a temperature of around 2566 K.
* TRAPPIST-1 is classified -: red dwarf star, the most common type of star in the universe.
* TRAPPIST-1 is a highly active star ,with strong stellar flares and winds that can destroy the atmospheres of the planets orbiting it. If the planets have a strong magnetic field, their atmospheres may be protected from the stellar wind.
* The TRAPPIST-1 system is called a "compact" system, since its planets are so close to each other.
* Because of its compactness, life could theoretically travel from one planet to the next from riding on impact debris, allowing life to spread everywhere in the system. The same can be applied to rockets travelling through the system.
* The planets are in orbital resonances, with the durations of their orbits having ratios of 8:5, 5:3, 3:2, 3:2, 4:3, and 3:2 between neighbouring planet pairs, and with each set of three being in a Laplace resonance.
* All the planets in that system are tidally locked which means one side of the planet faces the star, and the other in the shadow. That means On the planets, the part that faces the star goes into eternal daylight with high temperatures, and the other side being in eternal darkness (with low temperatures).
* There is one side (the twilight zone), that can be habitable, with temperatures there possibly being right for life to exist (with water not becoming frozen or being boiling hot).
* Some planets, like TRAPPIST-1d, e, and f, might have a 3:2 spin:orbit resonance like Mercury due to instabilities of the system.
* The planets are expected to have intense tides because of the interactions between the star and the other planets in the system.
* Some planets might have oceans covering their entire surface.
* The outer planets could have subsurface oceans below a thick ice shell like Europa.
