K. Minor pentacle

Completely collapsed circular room. Smell of sulfur mixed with something acrid (the demon's acid). Full of debris.

• → Collapsed. Secret passage to J partially open due to the cave-in.
• → Debris. Includes some human remains and pieces of partially melted rock.

Note: The demon Grazzalt (see B) overdid his intervention a little and not only killed most of the adventurers (except Reginald) but destroyed the room…
