Lord Xavius was a former Night Elf who ascended through the Quel’dorei to be the Counselor to Queen Azshara. Intrigued by the art of magic, he worked his way through the Highborne with such dedication that he gave up his own eyes for magical orbs allowing him to understand his art better. He led the creation of the portal that would allow Sargeras to venture into Kalimdor. He captured Malfurion Stormrage’s spirit form, who later escaped and killed Xavius. His spirit was captured by Sargeras, who tortured him and then resurrected him as the first Satyr, and sent him into the world to fill the ranks of the Legion. Later in the War of the Ancients, Malfurion, in a desperate bid to save Tyrande from the clutches of the Legion, kills Xavius for the second (and more permanent) time by turning him into a tree.
