Scion of darkness ruling and protecting those who live in the underworld, in opposition to Lahabrea the Abyssal Celebrant and scion of light. In the course of his rule, he submitted to avarice, and the darkness took his heart, transforming him until he was both evil and corrupt. Then in his cowardice did he bind a Goddess of the Demesne of Ice, and using her as a living shield, he challenged the gods. Defeated before their might, he fell screaming into the depths of hell, there to be imprisoned for eternity.
