Temple of the Damned (Warcraft II)

Temples of the Damned - called Grombolar, or bowels of the giant in the Orcish tongue - are the cabalistic dwellings of the dead. Created by Gul'dan to house his blasphemous Death Knights, the Temples were formed from petrified carcasses of the race of giants that inhabited the Orcish homeworld. The subterranean labyrinth of the Temple contains the fetid halls where the Death Knights dwell and study their depraved necromancy on fallen warriors reaped from the battlefields above.
