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 beneath 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.

Background
Azharul, the Dragonspawn Pits, were introduced as Tiamat's lair in the 1st edition Dragon article "The Nine Hells, Part I". 2nd edition made Tiamat's Lair a proper noun, not mentioning the former name. Ed Greenwood's forum article, attempting to reconcile the various locations of Tiamat's realm throughout the editions, introduced Azharul as a deity and placed the Dragonspawn Pits into the Dragon Eyrie. The exact relationship between Tiamat's Lair and the Cave of Greed/Dragonspawn Pits within the Great Wheel cosmology is not specified in the extant sources. It seems likely that the Dragonspawn Pits were kept as a secondary realm by Tiamat after the demise of Azharul.
