Silas is a lithe, whip-thin man with short, dark hair and striking, restless gray eyes. He wears fitted studded leather armor dyed the color of a moonless sky, and his fingers are long and calloused from years of working delicate machinery. He often carries a small silver wire tucked behind his ear like a carpenter might carry a pencil.

Quiet and intensely focused, Silas is a man of few words and many secrets. He approaches every locked door as a personal insult to his skill and views the architecture of a building as a playground of verticality. He is rarely found on the ground floor if there is a way to sit among the rafters or on the roof.

Silas Vane was raised in the shadow of the High City, the son of a disgraced clockmaker who taught him that every mechanism has a heartbeat. When his father was imprisoned for a debt he did not owe, Silas realized that the law was merely a series of tumblers designed to keep people like him in their place. He began his career by picking the locks of the very creditors who ruined his family, leaving only empty vaults and a single clockwork gear as his calling card. Eventually, his talent for reaching the unreachable caught the attention of the local syndicates. He spent years as a premier wire-walker, a thief who never needs to use the front door. However, the thrill of the steal became more important than the gold, and Silas now finds himself seeking increasingly impossible challenges to prove his mastery over the physical world. He travels from city to city, often hired for jobs that require a surgeon's touch rather than a mercenary's blade.
