Who is Illidan Stormrage

Illidan Stormrage, known as The Betrayer, is currently the self-proclaimed Lord of Outland, ruling from the Black Temple. He was born a night elf, and as stated by Maiev Shadowsong, is now "neither demon nor night elf, but something more". He is the twin brother of Malfurion Stormrage and was (perhaps still is) in love with Tyrande Whisperwind. Once an unusually gifted sorcerer, the extent of his powers today are difficult to classify, due to his powers increasing in large bursts as a demon hunter, sorcerer, and having absorbed the powers of the Skull of Gul'dan. His pursuit of power and arcane mastery has led him to commit a number of horrific acts against his own people and the races of Azeroth, including defecting to Sargeras during the War of the Ancients and creating the second Well of Eternity. For his actions, he was imprisoned for ten thousand years, until his release almost a decade ago. He has come to be called the Betrayer for his acts against the night elf people and now also carries the title of Lord of Outland. He was introduced as a Black Temple raid boss in Patch 2.1. Illidan is voiced by Matthew Yang King in Reign of Chaos and The Frozen Throne, and by Jeff Bennett in The Burning Crusade.
