Black TempleRequires The Burning Crusade
Long ago on Draenor, the Temple of Karabor was the center of draenei worship. But the devout priests who prayed there are long dead, slaughtered by marauding, demonically corrupted orcs. In the massacre's aftermath the warlocks of the Shadow Council seized the structure and bestowed upon it a new name: the Black Temple.
When Illidan the Betrayer fled to Draenor (now called Outland), he ousted the Temple's ruler - the pit lord Magtheridon - and claimed his throne as the lord of the blasted world. Despite the bitter retribution of his enemies, Illidan has begun to tighten his grip on Outland from within the profaned sanctum, where he awaits any and all who would challenge his rule.
