Mass Effect: Repercussions
The system where the SSV Normandy was destroyed. The action took place around the 4th planet, Alchera.
Alchera’s crust is composed of carbon and water ice. While low density, its large size allows it to retain a thick atmosphere of methane and ammonia. It is believed that if Alchera had acquired a bit more mass when the Amada star system formed, it would have formed the core of a second outer-system gas giant. Alchera has three moons: Uluru, Wandjina, and Baiame.
