The Forgotten Bridge is an area in Torvus Bog. It is a huge room with a giant bridge that can be moved with the Bomb Slot nearby, but the Bomb Slot is in a state of transdimensional flux on the surface Dark Aether. There are several Sentinel Crystals dotting the walls of the room. It is in this room that Samus first encounters Grenchlers. The dark version of this room is called the Dark Forgotten Bridge and can be accessed through a Portal located in the room. This is also the first place where Samus encounters Dark Pirate Commandoes. She finds them after moving the bridge in Dark Aether and warping back to Light Aether. They only appear here once.
