Zargon the Returner was an elder evil abomination who hungered to drown the world in its slime.[1]

Legends indicate that Zargon may have been the first master of the Nine Hells. Other stories say he was a Demon Prince that was thrown out of the Abyss.[2]

He was known to take on selected warlocks as their patron.[2]
