Dark Sun: The Scorched World of Athas
The Ivory Dungeon
The Ivory Dungeon is an underground complex beneath a section of Andropinis’s White Palace, accessible only from secret entrances. The Ivory Dungeon is made of white marble mined from just outside the city. The bars of its cells are polished bone, adding to the pristine and elegant appearance of the palace.
The sorcerer-king attempts to keep the existence of the Ivory Dungeon and it’s inhabitants a secret, although the information leaks out from time to time.
Jarvix and his allies are the only known group to infiltrate the Dungeon and escape with their lives.
