Rageal

This divine being that has been entombed by a magic seal goes by the title Lord of Light. Witnessed first by Araz as he walked through a mysterious torus within the Ruins of Alborect an encounter that left him exhausted and drained of magic. They encountered a servant of his, Caduceus, however he remains a complete mystery. From initial collaborations with David Moore it seems he cannot find any information regarding this deity's actual name or means of it's imprisonment, almost as if that knowledge has been erased.
Gaunter O'dimm reveals his true name, Rageal, to Pious after finding the Soul Anchor destroyed in the Ruins of Alborect.  Apparently another title for him was The Consuming Fire and was known for his vengeance.
