Corbin is a lean, handsome half-elf with warm brown skin, angular features, and shoulder-length black hair usually tied with a red silk cord. His green eyes carry a constant glint of amusement, while a thin scar cuts through his right eyebrow. He favors fitted dark leather armor beneath a fine burgundy coat, polished boots, and a collection of rings and signet tokens used for his disguises. His hands are nimble, well manicured, and rarely still.

Charming, observant, and unfailingly polite, Corbin treats every conversation like a puzzle with several possible solutions. He enjoys helping people while pretending he is only helping himself, and he is quick with a joke when the mood becomes too serious. Beneath his confidence is a guarded fear of abandonment, which makes him fiercely loyal once someone earns his trust.

Corbin was raised between two worlds, never quite belonging to either. His human mother worked as a traveling clerk and occasional confidence artist, while his elven father vanished before Corbin was old enough to remember his face. From his mother, Corbin learned that a convincing smile could open doors that locks could not, and that the difference between a scam and a rescue often depended on who benefited from the lie. He became adept at disguises, forged papers, marked cards, and slipping through guarded places without leaving more than a whisper behind. For years, Corbin used those talents to cheat merchants, nobles, and criminal syndicates, always taking care to target the cruel or the spectacularly greedy. His life changed when a forged inheritance document helped him free a group of children from a debtors' ring, but exposed his mother's identity to the gang that had once employed her. She disappeared during the escape and was presumed dead, leaving Corbin with her battered forgery kit and a list of names belonging to people who profit from the helpless. Now he travels as a gentleman thief and occasional investigator, using deception to dismantle predators from within. He still lies easily, but he has finally decided what his lies are for.
