Apophis was a “mature adult” black dragon who spent many years frolicking in the swamps of Africa with his wife, until a group of vigilante dragon hunters led by Bellamin Arroway murdered her. Apophis survived, and began to rampage throughout the countryside, leading to many innocent deaths. Before Bellamin and his gang were able to return to kill him, ‘s mother was able to find and placate Apophis. She led him deep into a mountain populated by dark dwarves, and convinced them to worship Apophis as their deity and herself as Apophis’s high priestess.
With the dwarves worshiping him, Apophis felt pretty good about himself, and all was peaceful again. Eventually, the heroes of our story found Apophis and were able to use his acidic breath to destroy an ancient artifact, as well as avenge his wife by destroying the physical body of Bellamin, who had since become a failed lich. Apophis took Bellamin’s phylactery and submerged it in a pool of his strongest acid, forcing Bellamin to endlessly be reborn and immediately dissolve.
