Medivh's mother Aegwynn, now banished from the realm for her misdeeds against the Order of Tirisfal, had figured out what Sargeras had done to her, and got into contact with King Llane and his general, Lord Lothar. Lothar felt he had no choice but to destroy the corrupted Medivh in order to prevent the evil Guardian from doing any more damage to Azeroth. Medivh's apprentice wizard, Khadgar, helped Lothar, King Llane and Aegwynn infiltrate Medivh's dark tower, Karazhan. Despite his enormous power, Medivh was caught off his guard, and was in the end killed by his former friends and comrades in his underground sanctum. His body destroyed, Sargeras was sent reeling in pain back into the Twisting Nether. There he remains in limbo, unable to access a vessel body powerful enough to hold his demonic spirit.
