The murderous DeGrasse had stolen the lives of countless innocents, but a virtuous sorceress finally put an end to his reign of terror. "The more you kill, the closer you shall draw to hell," she warned him before vanishing into thin air. But DeGrasse did not fully understand the import of her words. So he enlisted in the army and sated his bloodlust on the battlefield... until one day, he didn't recognize his own body.
