Brannoc is a broad-shouldered male dwarf with copper-brown skin, a square beard braided with bits of brass wire, and alert gray eyes magnified by a pair of hinged workshop lenses. His left eyebrow is singed away from a testing accident. He wears reinforced scale mail beneath a stained leather apron, with a shield mounted to his rucksack by a quick-release harness. The rucksack looks ordinary, but its frame is packed with nested tools, spare mechanisms, folded tripods, ammunition cases, and several devices that occasionally whir or click on their own.

Brannoc is eager, inquisitive, and incapable of treating a mystery as anything other than an invitation. He is warm with practical people, suspicious of grand speeches, and genuinely delighted when someone improves one of his designs. He asks questions at inconvenient times, but he remembers the answers and uses them to make better tools.

Brannoc Cleft-Cog was born between two brothers who seemed destined for entirely different kinds of certainty. His elder brother, Orvi, could look at a bar of iron and see the finished shape hidden inside it. His younger brother, Tovin, found purpose in oaths, armor, and the protection of strangers. Brannoc saw none of those things. He saw hinges that could move without squeaking, water wheels that could turn in dry seasons, lanterns that could burn without oil, and a hundred other questions waiting to be taken apart. As a young guild apprentice, Brannoc became known for building useful devices from scraps that other smiths discarded. His finest failure was a self-loading ore sorter that hurled gravel through the workshop roof and buried Orvi's chimney. Rather than disown him, his family helped him rebuild it, and Brannoc began carrying his expanding workshop in a deceptively large rucksack. He now travels as an artificer and licensed guild craftsperson, testing designs in mines, border settlements, and growing industrial towns. His ambition is not merely to become famous. He wants the Cleft-Cog family to become the name people trust when a new age demands a better machine, and he intends to make sure that age serves ordinary folk instead of grinding them beneath its wheels.
