D. Long corridor and secret maintenance closet

5'-wide, gently downward-sloping corridor, cool air. Door ajar in the first section. Stairs descend several meters after a 90-degree turn.

• → Door. In fact, a secret door, (a piece of retractable wall). Opens with a simple push from the inside and closes automatically after 30 minutes. The hinges are stuck and preventing it from closing this time. Opens onto a small room not shown on the map. This is where the moaning heard in B comes from.
• → Small room. Cramped, empty of any furnishings. A zombie paces back and forth, groaning, banging its head against the walls at each end. A little bell hangs from the ceiling.

OFF-DUTY ZOMBIE. Wears a Dungeon, Inc. Maintenance armband. Completely harmless unless attacked.

HD 2 (16 hp), ARM-, ATT bite d8, ML–

• → Little bell. The cord used to make it ring sinks into a hole in the ceiling.

Note: The cord is directly connected to Maintenance offices. It rings when the ogre is out, signaling to the zombies that it's time to get to work.

• → Stairs. Before descending the steps: a bizarre song in a guttural, thunderous and somewhat muffled voice can be heard coming from below. A dwarf will recognize a dwarven drinking song.
