What’s it up to right now?
For those that don’t know, the Blackfuse Company was a goblin-run firm focused entirely on manufacturing weapons of mass destruction. The Iron Star, the Juggernaut, and the world-breaker - these were all the brainchildren of the Blackfuse Company. They applied themselves wherever there was the possibility of profit and destruction - and as such devoted themselves entirely to the Iron Horde. The Iron Reaver is additionally one of their creations, created along with orcish engineers. After this, we don’t see much of the Blackfuse company, and one could presume that they all perished in our raid upon Hellfire Citadel.
BUT! I propose that they have, in fact, survived on AU Draenor. As the light continues to ravage the world, the resourceful and sadistic orcs and goblins of the company are working tirelessly to find new and disturbing ways of destroying things. None of them worship the light of course - but they find ways to weaponize it against the encroaching Lightbound in horrific ways. Mirror machines that can scorch cities in seconds, mechas that can simply heal themselves. Light infused explosives.
