Shade of Xavius

Once a powerful mage, and a councilor to Queen Azshara, Xavius forged a pact with Sargeras to enable the Legion's first invasion of Azeroth. Cursed and tormented in the wake of that defeat, Xavius now projects his true power from the Nightmare into our world, focusing his dark might to break the spirit of his old rival, Malfurion.
