Sanctuary Fortress

From Wikitroid, the Metroid wiki

An ancient place of Luminoth study, the Sanctuary Fortress is the vast stronghold that makes up Sanctuary Sector. It is built high on the cliffs of Temple Mountain, overlooking a shining ocean. Only mechanoids such as the Quad MB, Quad CM, Rezbit, Octopede, and the Ingsmasher remain in the fortress. Now serving the Ing, they see Samus Aran as a foe they must terminate. Its Dark Aether counterpart is the Ing Hive.

[edit] Glitch

One room in the Sanctuary Fortress has perhaps the most fatal glitch in Metroid Prime 2: Echoes. In Main Research, there are three sonic locks to deactivate. If for whatever reason you leave and re-enter the room without deactivating all three locks, you will not be able to open the door thus you cannot continue, unless you restart the entire game or perform what is known as a Kip Dash. 1 However, if you don't save the game after discovering this glitch, you can simply restart the game from the last save point.

[edit] Trivia

• Pieces of another Quadraxis can be seen in the Sanctuary Temple.
