The Blackfuse Company is a mercenary organization of Goblins and Orcs who construct siege weapons. Founded by Siegecrafter Helix Blackfuse, the Blackfuse Company affiliated with the True Horde led by Garrosh Hellscream, a traitor who betrayed the Horde for the sake of power, vengeance, and war. After the True Horde's fall, the Blackfuse Company still remained intact when the organization allied the Iron Horde and built Iron Juggernauts to be used for the Ironmarch.
