Malchezaar is the current ruler of Karazhan, however little else is known about him except that he is a Man'ari Eredar, and is possibly a sub-commander of the Burning Legion. He is considered by many to be the final boss of Karazhan, however, some consider the creature Nightbane, (who is only available to be summoned after killing Malchezaar at least once), to be the true final boss.
