The Deep Landing
A wide, flat room with nothing in it, directly under the entrance and three rings out. This is where people stop. The floor is worn in a broad ring from pacing, there are four separate tallies on four separate walls in four separate hands, and every one of them is a count of days rather than of marks.
A spinner waits just inside the west passage. It bears no sigil; whatever left it did not give a name.
Depth 3
You are reading the dungeon, not walking it. Rooms are only created by people, and only from inside the maze.
