The Aerie is a room in the Sanctuary Fortress area of Aether. It is the highest room in the sector, and is essentially a huge elevator. It is unknown what the purpose of the room was originally, but it seems to be a chamber for containing the Echo Visor. O-Lir refers to the Aerie as a "place of honor".
During Samus' exploration of the Fortress, she encounters and fights Dark Samus here, who she thought to be dead after their previous battle. Dark Samus has absorbed more Phazon since her defeat, increasing her own powers and giving her access to more Phazon variations of Samus' abilities, such as the Boost Ball and Super Missile.
Upon entering the room, Samus finds Dark Samus absorbing Phazon from a wall of the substance. Dark Samus becomes aware of Samus' presence, and fires at her. Managing to evade her attacks, Samus finds cover behind one of the two beams that go through the elevator platform. Dark Samus hits an Interface Module, activating the elevator. The two battle until the elevator reaches the top, at which point Dark Samus starts using more of her abilities, like becoming invisible to the Combat Visor.
Upon defeat, Dark Samus escapes by breaking through a window and falling out of it, granting Samus access to a Portal. Samus travels to the Dark version of the room, and uses a higher Portal to return. Samus then acquires the Echo Visor. By using it, Samus can unlock the sonic locks preventing her from leaving. The Dark Aether version of this room is the Hive Summit.
