Closet

A closet is a single square located behind a door. Often the door is a secret door.

Sometimes closets are generated without doors leading to them. The only way to get to these is for a corridor to be generated adjacent to them, or to teleport in. If there is a scroll inside these closets, it is almost certainly a scroll of teleportation. If you find yourself inside a closet with no means of exit or escape, praying can get you out.

There is sometimes writing in the dust outside. The engraving ad aerarium indicates that the closet contains a vault teleporter, and the engraving Vlad was here indicates that there is a trap door inside.

Monsters can be generated inside closets just like on any other square.
