The Crystal Kings
Dagon is any and all semblance of hedonism, cowardice, and evil left in Sysaphons when he ascended. Sysaphons cast out these parts of himself, in order to rule his people with true good, and sent them away. These pieces of Sysaphons coalesced to become Dagon. Dagon fled to Hells Fin after he was sent away and broods there, building an army to destroy Sysaphons and return to Elianor.
