Tomas Vey is a lean, weathered half-elf with brown skin, close-cropped black hair, and a narrow scar running from his left eyebrow to the edge of his cheek. His green-brown eyes rarely stay still. He wears a patched dark leather coat over a faded gray shirt, soft boots, and a red thread bracelet that once belonged to his younger sister. His hands are callused from climbing, lockwork, and years of surviving jobs he never wanted.

Tomas is quiet, observant, and dryly funny when tension is highest. He treats every conversation like a puzzle, but he is gentler with frightened people than he knows how to be with himself. He prefers practical help to grand promises, keeps track of everyone's injuries, and becomes intensely focused whenever someone mentions disappearances, coerced labor, or coded messages.

Tomas Vey grew up in the river district of a crowded trade city, the son of a half-elf dock clerk and a human seamstress. He and his younger sister, Neris, learned early that hunger made honest work feel like a luxury. When their father died, Tomas accepted an offer from a local burglary crew that promised quick coin and protection for Neris. He told himself he was only carrying messages and opening doors, but the crew soon made him an accomplice to robberies, blackmail, and the quiet disappearance of people who could not pay their debts. The life ended during a job at the house of a magistrate. Tomas discovered that the target was not a ledger, but a list of children being sold through the magistrate's network. He tried to destroy the records and get the children out, but the crew turned on him. Neris, who had been serving as his lookout, was captured in the confusion and taken away by the crew's leader. Tomas escaped with the ledger and spent the following years dismantling the operation piece by piece. He now works as an investigator, thief, and reluctant informant, using the same skills that once harmed people to expose those who profit from cruelty. Every trail eventually becomes a search for Neris, who may still be alive, and every good deed is an attempt to earn forgiveness from someone who may never return.
