Patch 2.1.0, titled Black Temple, is the first content patch for The Burning Crusade which released on 22 May 2007.
In his quest to reign over all of Outland, Illidan the Betrayer had established a mighty stronghold for his forces within the Black Temple, a former draenei citadel. Yet his influence began to wane after the defeat of his most trusted lieutenants, including the traitorous former leader of the blood elves, Kael'thas Sunstrider. The resulting window of opportunity permitted Akama, an elder sage of devolved draenei known as the Broken, to rebel against the self-styled "Lord of Outland." Along with Illidan's former jailor, the stoic night elf Maiev Shadowsong, Akama helped a group of heroes infiltrate Illidan's seat of power and put an end to the Betrayer's reign once and for all.
