Daemon is a broad-shouldered goliath with slate-gray skin, a powerful build, and dark hair kept carefully slicked back. He dresses in expensive-looking charcoal suits bought with fight winnings, though the cuffs are repeatedly repaired and the collars show careful wear. His clothes are tailored to emphasize his size, and he wears polished boots that make his entrance unmistakable in any back-alley club. His most noticeable feature is the contrast between his immaculate grooming and his battered knuckles, which he keeps wrapped in clean white linen when not fighting.

Daemon is controlled, observant, and aggressively self-reliant. He presents himself like a gentleman because appearances are armor, but beneath the polished suit is a suspicious street survivor who expects betrayal. He respects competence, physical courage, and people who keep their word. He has little patience for excuses, inherited privilege, or anyone who treats magic as a substitute for discipline.

Daemon Flint was born on the neglected edge of a settlement that was becoming a city faster than its people could adapt. His parents abandoned him while he was still young, leaving to seek a better life elsewhere and never returning. Daemon grew up among alleys, loading yards, and crowded tenements, learning early that promises were usually made by people who already had somewhere safe to sleep. He survived first as a scrappy thief, stealing food, purses, and anything else that could be traded before the city swallowed the neighborhood whole. As he grew larger and stronger, Daemon traded nimble fingers for heavy fists. He learned to fight in illegal clubs beneath taverns, warehouses, and abandoned bathhouses, eventually earning enough to buy fine suits and build a reputation as one of the city's most dangerous pugilists. His time as a soldier taught him discipline, formations, and the value of striking first, but it never taught him loyalty. He resents his parents, the city's powerful elites, and especially those who wield magic, whom he sees as people granted unfair power without having to earn it. Now he moves through the city as a well-dressed professional bruiser, collecting debts, favors, and enemies while using his old military connections and underworld contacts to find the next profitable fight.
