Varimathras is a Nathrezim demon who originally served the Burning Legion. He was forced into allying with the Forsaken, under the direct control of Sylvanas Windrunner, in exchange for sparing his life after he and his fellow Nathrezim were overcome by her undead forces. Though he swore allegiance to Sylvanas, Varimathras remained loyal to the Legion and eventually staged a coup for control of the Undercity with Grand Apothecary Putress. He is still believed to be within the Twisting Nether, plotting a return to Azeroth.
