Daenum Arum, a lich that besieged Rose in 1001 AC returns as the Desert God.
He harnesses power through seven Phylacteries in the form of Black Candles.
Each Phylactery is held by a chosen Acolyte. When a Phylactery is destroyed, a major catastrophe plagues the world, as part of Daenum Arum's curse.
The Desert God raised the armies of the undead from Blacktail's underground catacombs.
The Acolytes seek to manipulate the Kings of other nations.
Cordelia's Dark Child is a lever for such pressure, she is to be possessed to charm the king.
