Blackrock CavernsRequires Cataclysm
Rumors suggest that Deathwing himself carved out the subterranean labyrinth that allows the Twilight's Hammer to secretly transport elementals from the majestic Mount Hyjal to Blackrock Mountain. A vital hub of this shadow network is Blackrock Caverns, site of the cult's blistering forge and some of its most heinous experiments, including the transformation of cultists into twilight dragonkin.
In the bowels of Blackrock Mountain, beneath the more traversed parts of the mountain's spire, the Twilight's Hammer puts this hope into practice. Surrounded by boiling spouts of magma and burning rock - as well as the dangerous elementals that call Blackrock home - the cult will reforge their devoted in the image of the world they work to destroy.
