Cheklov's Lair

Deep within the Ossuary lies a chamber floored in ornate tile work depicting the phases of the moon and the pattern in which eclipses fall. In the center of this room lay a pool, deep and black but for the dim glow of bio-luminescent fish darting here and there in the depths. The pool matches the phases of the moon, the fluid within growing more opaque as the moon creeps towards darkness until it becomes a perfectly dark mirror.

Elke and her mates, obviously, make this room their personal lair.
