Duke Omaroch d'Zarnagon is an archdemon and the youngest son of Grand Duke Malakhia and Grand Duchess Nhrakate of the House of Zarnagon. His curiosity led him into the Land of the Living where he eventually fell in love with Delora, a human cleric of Cardia, with whom he had two sons, Kareth and Refan. This caused a rift between him and other demons, and it eventually led to a personal tragedy from which he has never fully recovered. He worked for the Magicracy of Alent after the Cataclysm and joined the Andarian Empire in the Fourth Age.
