Sarait

Description
A large terrestrial, Sarait's methane-rich atmosphere might be mistaken for that of a true hothouse planet. However, some terraforming corporations have targeted it for development since Sarait has already given rise to some cyanobacteria in the liquid water that can be found near its poles. There is some evidence that the planet has been fluctuating between methane-heavy and oxygen-heavy atmospheres for several million years, each cycle dependent on the nutrients in the ocean that led to bacterial growth or crashes.

Star charts catalog several scientific stations studying Sarait, but all appear to have been destroyed by the Reapers.
