The Sentinel's Path is a room in the Sanctuary Fortress. It appears in Metroid Prime 2: Echoes.


The Sentinel's Path is connected to the Sanctuary Temple. Upon the first entry, a single Quad seems to jump from the ceiling of the room, where it may have been laying in ambush. After defeating Quadraxis it is replaced by two Mekenobites. An Echo Key Beam System blocks access to a missile expansion behind a broken wall in the middle of the room.

Strange enough, the path can be entered from only one direction, unless Samus has acquired the Annihilator Beam. This makes the path useless as a shortcut until after Quadraxis's defeat.

The Dark Aether equivalent of this room is Temple Security Access.
