Technically he can be described as God's immorality, we use a modified religion around here. Koty's background is that after God made the world he realized that he had evil within himself, and since he could not purify it, he removed it. And this made "Him", Ararus, Koty, whatever name he goes by.
This made him the polar opposite of God, the original Satan/Devil. Events led to him being banished to Erebus, the true hell, he was then sealed and Lucifer was named his successor for control over the demons.
