The long night has come. The Systems Commonwealth, the greatest civilization in history, has fallen. But now, one ship, one crew have vowed to drive back the night and rekindle the light of civilization. On the starship Andromeda, hope lives again.
The series is set thousands of years in the future, and revolves around the Systems Commonwealth, a republic based in a distant star system called Tarn-Vedra. Humankind is a part of The Commonwealth, having been discovered by its members thousands of years before. The Commonwealth spreads across three galaxies: the Milky Way, Triangulum, and Andromeda, with Tarn-Vedra near its core. Ships travel from one end of the Commonwealth to the other through slipstreams, following roller coaster-like pathways through the cosmos to and from their destination.
The Commonwealth claims to be a utopian society, but it is actually in a state of war with the Magog, a predatory humanoid species with bat-like faces that is dedicated to war.
