The Mutated Foreman

Appearance
Once a respected dwarven foreman named Thrain, the Mutated Foreman is now a grotesque fusion of flesh and industrial mining equipment. His left arm has been replaced by a whirring, Aether-powered drill, and his skin is a translucent, sickly gray, revealing glowing veins of unrefined Aether-sludge beneath. His face is partially obscured by a rusted iron welding mask fused to his skull.
Personality
The Foreman is a mindless, rage-filled brute, driven by the constant, agonizing pain of his transformation. He no longer speaks any known language, instead emitting a series of binary-corrupted screeches and mechanical groans that sound like grinding metal.
Secret Motives
He has no personal goals remaining; he is a tragic thrall to the toxic Aether leak. He is instinctively drawn to sources of raw magic and seeks to destroy anything that hasn't been corrupted by the "Sludge," viewing unmutated life as an irritant.
Combat Tactics
The Foreman charges blindly into melee, using his massive drill-arm to bypass the heaviest armor. He is incredibly durable and leaks highly toxic Aether-sludge when damaged, creating a hazardous aura around him that poisons and burns anyone who stands too close. He can also slam his drill into the ground to create localized earthquakes.
