Silas stands with a rigid, unnatural posture that suggests he is constantly bracing against a heavy wind. He wears exquisite, heavy silks of midnight black, embroidered with gold thread in patterns of geometric interlocking gears. His light blonde hair is cut short and neat, contrasting with a thin, meticulously groomed salt and pepper beard. His most striking feature is his left eye, which has been replaced by a fist sized, multi faceted iridescent gemstone that hums with a faint, rhythmic vibration. While his right eye is a piercing blue, the gem eye reflects colors that do not exist in the natural spectrum. He moves with a slow, deliberate grace, as if every step was calculated minutes in advance.
