Long ago, even before the Dawn War, Tharizdun discovered a shard of pure evil and decided to incubate it in a remote corner. The result was the Abyss, and the experiment drove Tharizdun to madness. In a rare show of solidarity, the rest of the gods opposed him with a unified front and eventually Pelor and Asmodeus imprisoned him in an endless and formless void. Tharizdun is commonly worshiped today in the guise of the Elder Elemental Eye, and has co-opted the aid of five Primordials to serve as his exarchs until he is able to find a way to escape from the Void. What would happen if those Primordials found out they actually serve a god is unknown and something most do not wish to contemplate.
