Storyline
Background
Pre History
After centuries of excruciatingly brutal murders in Christ's Crown, New York, the demonic Mephisto drew the concentrated evil of the area into a "son" he named Blackheart. Blackheart would profit from the power and teachings of the powerful Mephisto, whilst simultaneously rebelling from his father in an attempt to take his place on the throne of demons.
