Slight but taut, Derrin moves like a coiled string pulled taught then released. His ash-streaked, mud-scarred cloak hangs over slouched shoulders and is pinned with a small pin stamped with the symbol of The Bloodbound Covenant. He favors dark, travel-worn tunics that hide soot and scorch marks. His face is narrow with a crooked nose healed badly, a thin pale scar that climbs from temple to jaw like a white root, and a perpetual half-smile that does not reach his eyes. Unexpectedly, he keeps a single bright blue ribbon tied around his left wrist; it rattles softly when he moves and looks absurdly cheerful against his otherwise sullen palette.
