Catari

He appeared in the IDW comic Fallen Angel: Reborn as the former Qwa Ha Xahn of the Old One Illyria. As the High Priest of the God King of the Primordium he was "elevated above all that live."

When Illyria was destroyed and sent to the Deeper Well he begged for mercy to the Old Ones that destroyed his master, they sealed him in the North Pole, to defend one of the three icons of Illyria (the scythe looking weapon she holds in her primordium form).

When Illyria arrives with Liandra, she demands the return of her icon, but he refuses, betraying her, because if he surrendered the icon he would die.

After a short battle, both kill him, his body falling to the depths of the Artic Ocean.
