The Labyrinth is a maze in a remote part of the Gnawer's domain. It is usually rarely visited by them. In The Prophecy of Bane, Regalian spies identify it as being the hiding place of the Bane. It can be accessed by several Underland tunnels, as well as the Waterway. Upon arrival to it in the Prophecy of Bane, Gregor and the rest of the party are separated from Luxa, Boots, and Aurora. Somewhere inside, Gregor and Ares leave a severely injured Twitchtip, seeing her for the last time.
