This L-shaped area is accessed from the door in DEC 22. Immediately from entering at the door, there’s a solid set of mossy black stone stairs going 5 yards downward into the area proper. There’s two legs of this area, one going north-west for 15 yards and another going south-west for 20 yards. Both legs are 6 yards wide. The walls, floor and ceiling of the area are solid black stone ravaged by time and intense violent activity. Much of the place looks close to crumbling, and the completely absent signs of life only add to that feeling. No furniture or decoration can be found in this place. There are no light sources in the area, leaving it in total darkness. The air here is very stale, even hard to breathe.
What the heroes may not see in the inky black depths is that this area is almost overrun with nastiness. There is an Ooze clinging to the ceiling above in the north-west leg of the area. In the south-west leg of the area, there’s 20 (5 by 4) square yards of Green Slippery Mold (20 HP, SM +2) covering the central floor. Right nearby, there are 7 Blinding Coughing Spore Clouds drifting through the air. The kicker on all this is the squad of N Shadow Warriors (Monsters 3: Born of Myth & Magic page 21) who took this area for their own lair.
Examining the stairs into here from DEC 22 can allow a roll (-6 modifier) to find a small hidden compartment concealed within the stonework. The compartment contains 250 silver coins.
At the end of the south-west leg, there is an elevator contraption built into the east wall that allows a 5 yard descent (the elevator takes 5 seconds to make a trip up or down) into the DEC 27 area. The elevator is activated by a button on an interior control panel (and buttons on the walls next to it in areas DEC 26 and DEC 27 call the elevator when pushed).
