The West Stair Head

Six steps go up from here and end at a wall, which is the sort of thing this dungeon does. The treads are worn in the middle, so the wall came later. A handrail bracket remains, holding nothing, polished bright by a great many hands that must have known perfectly well the stair went nowhere.

Depth 4

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