WoW - The Black Temple @ Official Site
A preview of the upcoming World of Warcraft patch is available at the official site.
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.
