Azharul

Azharul was a dragon deity who lived in Dragon Eyrie.

Realm
Azharul realm was known as the Dragonspawn Pits, located in the Dragon Eyrie lowest region, known as the dark roots.

History
Azharul was an old rival of Tiamat in the draconic pantheon. For that reason, after Tiamat's realm in Heliopolis was discovered to be a hoax by members of the Twisted Rune, in 1371 DR, she mind controlled those members and with their aid, killed Azharul on its realm, and subsumed its divine essence, taking his body and divine realm, completely unbeknownst to anyone but herself.
