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 (from the Latin "to the treasure") 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.
