|Affiliation(s)||Kirin Tor, Council of Tirisfal|
Arrexis was a powerful and well known member of the Council of Tirisfal as well as an archmage of the Violet Citadel around the First War. He wielded , the staff of Alodi, the first Guardian. He was described as a respected, great sage.
From his camp in Deadwind Pass, Arrexis was performing research on Karazhan and the way it bends reality. He found a way to stop the warping from happening within special wards, but while bringing the wards up reality was weakened. Medivh, who was possessed by Sargeras and secretly killing members of the Council of Tirisfal in "accidents", encouraged Arrexis to try his ritual on demonic realms. Arrexis caught the attention of the eredar Balaadur. The catastrophe ended with Arrexis and all of his apprentices dead, Balaadur taking Ebonchill, Daio exiled from the Kirin Tor for his part in it, and all records of Arrexis destroyed and stripped from Kirin Tor records so that no one would repeat his mistakes. Even Meryl Winterstorm, the remaining founding member of the Order who was absent for much of these events, was not told of what had happened to the missing Arrexis.
