Cave of Greed

The Cave of Greed, formerly known as the Dragonspawn Pits of Azharul (or more simply Azharul or the Dragonspawn Pits), was the divine realm of the draconic deities Azharul and later Tiamat.

Cosmography
In the Great Wheel cosmology, the Dragonspawn Pits were found on Avernus, the first of the Nine Hells. In the World Tree cosmology, the Cave of Greed was located in the lowest reaches of the Dragon Eyrie, far underground below the slopes of the mountain.

Description
The realm consisted of an enormous convoluted cavern which contained the lair of its deity and, at some distance, those of its various petitioners and other inhabitants.
