Kandel is a compact forest gnome with copper-brown skin, a narrow face, and thick black hair clipped short on one side with brass pins. Their green eyes are magnified by smoke-darkened spectacles, and their fingers are permanently stained with oil, blue dye, and powdered silver. Kandel wears reinforced scale mail beneath a patched leather apron, with a shield-shaped toolbox strapped across their back. A tiny clockwork lizard usually rides on their shoulder, occasionally clicking its jaws at strangers.

Kandel is intensely observant, quietly kind, and more comfortable with machines than crowds. They treat every object as if it has a hidden history and every stranger as if they might be carrying a problem worth solving. Kandel dislikes grand speeches but will spend hours making a small repair for someone who cannot afford it.

Kandel was raised in a hidden forest gnome settlement where every household repaired something for every other household. Their family maintained the village's rain gauges, root-cellar locks, and lantern beetle habitats. Kandel showed little interest in repairing objects exactly as they had been made. They preferred asking what an object was trying to become. A broken trap became a harmless warning device, a cracked kettle became a steam whistle, and a dead music box became a tiny machine that sang only when someone lied nearby. Their curiosity brought them to a traveling guild of instrument makers and locksmiths, where Kandel learned that invention could be a trade, not merely a private obsession. During an expedition to recover stolen guild designs, Kandel found the half-built body of a mechanical hound abandoned in a burned workshop. They repaired it using mismatched parts and gave it a gentle disposition, but the machine still remembers sounds from the night its maker died. Kandel now travels with the hound, selling repairs, exposing counterfeit work, and searching for the missing final design that might explain who ordered the workshop destroyed.
