"We do what we must to survive. We've made many concessions and thrown our lots in with the Greenskins, but as their masters, not as slaves. Of course, our values would never have been compromised had it not been for the betrayal of the past."
- —Zhorgrath, Chaos Dwarf Engineer[1a]
Chaos Engineers are the engineers of the Chaos Dwarfs who are masters of both science and Dark Magic and use their foul knowledge to create many of the Chaos-corrupted machines, weapons and hellish devices which allow the Dawi-Zharr to maintain their realm.
Toiling in the great foundry cities of the Chaos Dwarf empire in the Badlands are masters of the craft, individuals capable of bending ores to fit their evil vision. Unlike the Skaven of Clan Skryre, the Chaos Engineers do not rely on warpstone to create their war machines, but rather the very essence of magic itself.
It is from their dark imaginings that the Hellcannon was born, to say nothing of the other devices the forces of Chaos employ in their wicked crusades against the Empire of Man and the rest of the Old World. When not labouring for decades over a single invention or device, Chaos Engineers will shoulder arms and join the ranks of the Chaos Dwarf host to slaughter those who oppose them.[1b]
