The Eastern Threshold

The last of the dressed stone is behind you. Ahead the passage narrows and goes on east without ceremony, unlit and unmarked, into the part of the dungeon nobody has written down. Someone has left a boot standing upright against the corner, laced, as if they mean to come back for it.

Depth 4

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