Silas is an unnervingly tall and slender figure who moves with a predatory, liquid grace that lacks the natural vertical bob of a human gait. His skin has the texture of fine, cold marble, and his features are sharp enough to look sculpted from ice. He often stands perfectly still for minutes at a time, resembling a statue until he suddenly blinks or speaks. Contrasting his monochrome and morbid aesthetic, he always wears a fresh, vibrant yellow sunflower pinned to his lapel, which he touches gently when deep in thought.
