Adventure Guide
''This foundry was the ancestral home of the Blackrock orcs, wherein master smiths smelted and worked the impossibly hard ore that is the clan's namesake. Now, massive giants captured and broken by the Thunderlord heat the great forges, flamebenders of the Burning Blade imbue the ore with an inner fire, and engineers shape the slag according to otherworldly schematics. Warlord Blackhand's foundry is the center of the Iron Horde's military might, churning out the weaponry that will be used to raze Azeroth.''

The foundry has a shipyard where the dreadnaughts of the Iron Horde are forged and assembled before being sent to the Iron Docks.

After the fall of Blackhand, the Iron Horde under the new leader,, retreated from the foundry to Iron Docks and from there to Tanaan. It was still active as new munitions, cannons and supplies of parts for the Iron Reaver were being sent to Tanaan's.
