For years he has been exile, returning to claim his rightful place as the ruler of the earth. He proclaims that he is the first vampire, not satan or caine or anyone like that. He tells that the scriptures of the known bible are broken and that they were wrong on who the snake who tempted eve was. Turns out Adam was the snake and was the cause for them to be sent out of eden. He fights the devil for halo who is the reincarnation of Eve, his wife, and he has only come to take back what is rightfully his. His wife and the known vampire world that are his children.
