What does Blizzard sasy about The Black Temple:

Originally founded as a Draenei temple, this plot has been conquered and despoiled many times throughout the history of Outland, removing any spiritual grace it may have once held. The Black Temple has been the stage of the Orc Horde's blood curse, a fortress for the then-mortal Ner'zhul, and a prime staging ground for the Burning Legion's campaign of destruction. Most recently, it has been claimed as home by Illidan, where he and his minions make their bid for power over the remnants of the shattered planet. Now, it is up to you to face the malefic forces of Illidan and his minions in hopes of freeing Outland from chaos and tyranny.
