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 one of the higher end skills available in Domination.
