Silas is a man of rigid posture and industrial grit. His skin is the color of cooling ash, providing a stark contrast to his piercing, icicle-blue eyes which are perpetually ringed with dark shadows and bloodshot veins from sleepless nights over blueprints. His most striking feature is his hair: a meticulously kept mane of steel-grey that has never been cut, following a strict ancestral vow. It is often braided into tight, intricate coils held together by copper pins. When working, he is a figure of soot and leather, wearing a heavy apron and a specialized glass visor. In the boardroom, he transitions into a formidable naval blue great coat with reinforced pauldrons that carry the silver gear-and-rail heraldry of his consortium. He moves with a heavy, deliberate gait, his hydraulic gauntlets emitting a low, constant hiss of escaping steam.
