Andromeda

The series is set thousands of years in the future, and revolves around the Systems Commonwealth, a constitutional monarchy 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 prior. The Commonwealth is based out of three galaxies; The Milky Way, Triangulum Galaxy, and the Andromeda Galaxy, located 2.7 million light-years from the Milky Way Galaxy. Ships travel from one end of the Commonwealth to the other through slipstreams, following pre-guided roller coaster-like pathways through the cosmos to and from their destination.
