ME2 alchera - normandy monument
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.
