Silas is a man of average height with a wiry, flexible frame. His skin is pale and often smudged with soot or grease, and his dark hair is cropped short to avoid catching in gears. He wears well-worn scale mail under a hooded criminal cloak, and his belt is heavy with pouches of tiny copper springs, glass lenses, and customized tools.

He is clinical, calculating, and rarely raises his voice. Silas views the world as a complex series of tumblers and pins that can be solved with enough focus. He trusts gears more than people because a machine never lies to you about its purpose.

Silas spent his youth in the slums of a massive port city, working for the Grey Hand syndicate. While other orphans were used as runners, his nimble fingers and obsession with mechanics made him the gang's premier locksmith. He didn't just pick locks, he understood the math and magic behind them, eventually teaching himself how to infuse his tools with arcane energy to bypass even the most complex vaults. During a heist at a wizard's tower, he discovered blueprints for magical contraptions that changed his life forever. Rather than turning the papers over to his boss, Silas fled with the knowledge, becoming a freelance tinkerer on the run. He now utilizes his illicit skills for dungeon delving, finding that ancient ruins are simply much older, more dangerous vaults to be opened.
