Maximilian Ray:
A human. He was once considered a powerful seer by his people. While exploring the future he was set upon by Gram, a demon from the nether. Gram transformed him, and turned him into a murderer. He killed his village and traveled to more civilized land. After antagonizing the people of Wing City for ten years, Maximilian's soul now houses another being. Seraph.
Grahm:
A demon. He was born in the eternal fires of the Nether, and spent a million years trying to find a suitable host. He found Maximilian, and attacked at the man's most vulnerable time. When he was out of his body. The demon assumed that he'd break the connection with Maximilian's body, and be able to keep it for himself. Much to his dismay, Maximilian stayed connected with his body and must now share it with the demon and the being of Justice.
Seraph:
A being of Justice. He isn't an angel, but a doer of good. A good Sumeritan. He invaded Maximilan's body and gave the human the controls to his body again. Now Seraph and Gram must battle for control, and all the while try to convince Maximilian to do their bidding.
