Vox is a lean human man of average height, with soot-darkened knuckles, close-cropped black hair, and a narrow face usually half-hidden beneath brass-rimmed workshop goggles. Within a minute of meeting him, people notice that his eyes rarely settle on faces. He studies hinges, buckles, weapon grips, exits, and anything that might conceal a mechanism. When standing still, he places most of his weight on the balls of his feet, as if waiting for either a customer or an explosion. His layered leather apron is reinforced with hidden pockets, copper wire, folded diagrams, and several suspiciously well-made tools.

Vox is observant, restless, and intensely practical. He is more comfortable around tools than crowds and more trusting of a mechanism than a promise. He enjoys explaining how his devices work, but deliberately leaves out one crucial detail so that listeners cannot reproduce them without him. Beneath his criminal professionalism is a genuine fascination with invention and a guarded desire to prove that he is an artist, not merely an arms dealer.

Vox learned craftsmanship in the back room of a respectable clockmaker, where he discovered that the same precision used to build music boxes could produce a spring-loaded dart launcher, a silent lockpick, or a compact device capable of cracking a door without leaving obvious damage. He became fascinated by the practical mathematics of illegal weapons. Every mechanism was a conversation between pressure, leverage, timing, and human fear. His first independent commission was a palm-sized repeating crossbow built for a smuggler, and the payment was enough to convince him that legitimate work was merely underfunded criminal work. His operation ended when one of his clients used a weapon to murder a city official. Vox escaped through a drainage culvert with only his tools, notes, and a half-finished prototype. He insists that he is not responsible for what people do with his inventions, but he has quietly begun designing devices that fail safely in the hands of fools and work perfectly for those clever enough to understand them. Now he travels under the name Vox, manufacturing illegal weapons, selling specialized tools, and looking for buyers wealthy enough to fund his next breakthrough.
