Mortos is the younger sibling of Hades, god of the underworld. Mortos goes through the underworld picking out lost souls to become undead, for, although he never got one, he believes in second chances. All he ever wanted during his eternal life was to be forgiven, for one day, when he was a young god, he devoured the cattle of Helios, the sun god. Helios set him ablaze with his mighty heat, and the flame can never go out, so he burn for eternity.
