Samus overlooking the Ing Hive.
The Ing Hive is the Dark Aether version of the Sanctuary Fortress, the center of Ing activity. It is an enormous rocklike building overlooking a poisonous ocean. The Hive Temple is guarded by Quadraxis. As its name implies, it is the only known place that contains Ing Larva Swarms, making the Hive possibly the birth place of all Ing classes. Interestingly, this is one of the very few areas in the game with only one boss.
