With lucidity restored to him, there were some - particularly the red dragonflight, and even members of his own - who did not like where his mind was going. Believing that the spellcasters of the mortal races were responsible for all of Azeroth's troubles, Malygos began a terrible war to purge the world of "rogue" magic users, including the Kirin Tor of Dalaran. Realizing the situation had grown out of hand, Alexstrasza rallied the remaining dragonflights in the Wyrmrest Accord to combat Malygos' genocidal crusade. After much conflict around the Nexus, heroes entered Malygos' inner sanctum with the aid of the red dragonflight and defeated him, ending the war and depriving magic of its appointed guardian at a crucial turning point.
