Pentagram room

The stairs climb to a stone room whose walls, floor, and ceiling are covered with runic circles and pentagrams of all sizes and shapes. For once, marketing decided that "less is more" and left the room as it was. They even left the various pamphlets for planar holidays pinned to the double doors in the north wall. Apart from disarming the trap on the doors, the clients have wisely avoided to touch anything.

▶ Special effect: None.

→ Pentagrams. Used for protection, summonings, and divination. The largest is a teleportation circle. This is how Zénopuce will come back.
→ Doors. The client entrance. They lead to a winding stairwell that leads to the Bright Outside.
→ Trap. A wire-triggered alchemist's grenade (fiery explosion for 3d6 damage, area).
