Eccentric inventor: Brasswick

Eccentric inventor, soot-stained, brilliant, and perpetually distracted

Prompt: Masculine, middle-aged, human. A rapid-fire, enthusiastic pace with a gravelly, soot-stained texture. High energy and intellectual intensity. Features a slight eccentric rasp, often trailing off into technical muttering. The tone is helpful and brilliant but perpetually distracted by the next mechanical breakthrough. Mid-range pitch with sharp, rhythmic articulation.

Script: Careful with that regulator, my friend, she hums sweet until you insult her tolerances; now, if I shave half a tooth off this gear—ah! There it is, elegant, impossible, and nearly safe.
