The Upper Bend
The floor climbs here, gently but unmistakably, which no other passage in this part of the dungeon does. It is the only place that feels like it is going back toward the world, and it is not; it levels out and turns north and keeps going. Boot prints in the dust run both ways and there are more coming back than setting off.

You are reading the dungeon, not walking it. Rooms are only created by people, and only from inside the maze.
