Gehenna

An alien, human hybrid named Alastor discovers he is not alone. Abandoned at birth, Alastor's mother and father left him with no explanation of who he was or what he would have to do. The only thing his father left him with was a deep and burning hatred for everything. A once peaceful Queen of The Seven, Kakos, turns dark while brooding and trying to hide the truth about her son. She wants Alastor's father and his new lover dead for reasons Alastor doesn't understand. Kakos becomes the sole focus of Alastor's hate and anger, which has blinded him to the consequences of his actions. This blind hate and rage will have grave consequences for Earth and every living thing on it. Hate breeds fury, fury causes downfalls.
