Abbadon
Also known as the Destroyer of Worlds, Abaddon was a black pit of unquenchable, unthinking hunger in the deepness of space. Its sole purpose was to consume everything that lay in its path. Abaddon was destroyed when it tried to consume the star known as Ethian.
The subsequent release of energy created the God Apollyon and the Goddess Aurora. Shaitan defeated Apollyon shortly thereafter and absorbed Him, becoming Sartan, the Malevolent.
