This hallway is unlit. The air is warm and
humid and there are large puddles of water on
the floor, coming from under the wall that
connects with room # 15A. This wall is actually
a permanent illusion. It will NOT disappear if
touched, but can be penetrated if successfully
disbelieved, or more simply if the (unlocked) <cf. illusions, DLA>
illusory door in its center is opened. PCs cannot
see through it in any event unless it is dispelled.
The black dragon in room #15A
knows of this illusion, and may attack through
it, gauging its attacks by careful hearing. It
will try to attack by surprise before the door is
opened.

15A. Chamber of the Wyrm
This room is dank and unlit, and is filled
with the odors of decaying vegetation. Near <Odor Detection, DSG>
the far wall of the room is a young adult black
dragon (no speech nor magic use). It is not
sleeping. Lolth permits this pet of hers to keep
a small amount of treasure to play with, which
it piles around its tail. The treasure consists of
10,000 cp, 400 sp, 600 gp, 3 gems (1,000 <star rubies>
gp each), a bejeweled buckle (9,000 gp), and
3 potions of healing (3 x 200 XP).
