Iota system

The Iota star system is located in the, largely unexplored, Orion Arm of the Milky Way Galaxy.

It is 103.2 light-years from the Sol star system. The system has eight planets, an asteroid and kuiper belt, and a red giant star.

In 2334, a few million Christians secretly moved to the system, first colonizing the only Class-M planet in the system, Iota Four. Then Iota Three in 2348 and Iota Two in 2357.

Later on when The Movement was started, their headquarters were located underground on the acidic second planet.

The system is also known to have been completely uninhabitited before it's colonization.
