The Culverted Drain

A drowned room, and you are standing in the only part of it that isn't. The space opens out into a chamber of some size, roughly 4 by 4 paces. An arch no deeper than a stride leads into it through solid rock. The floor is scoured down to bare stone, cleaned the way only a torrent cleans. Someone has scratched a tally into the wall — 46 marks, the last one shallow, unfinished.

Depth 46.

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