Xenophage is a Chaos Lord, the first Lord encountered upon entering the Chaos Plane. It is through him that the first mortals transcended, those who in time became the first Occultists. During the Second Chaos War, Jy'Barrak Golgotha, aided by Xenophage, cast Pazuzu out of the Chaos Plane and onto the Prime Material Plane. It is said that Xenophage even today will barter with those strong enough in Domination to dare to do business with him.
