Rennic is a lean young man with the restless, half-collapsed posture of someone who has spent more nights on watch than in bed. His skin is sun-bronzed and wind-chafed, with a faint scatter of pale scars across his forearms where practice blades have bitten him during too many unsupervised drills. Sandy blond hair falls constantly into his eyes, usually damp with sweat, and he brushes it away with the back of his wrist instead of a proper gesture, as if there is always something more urgent than grooming. His green eyes are bright and earnest, but when he is excited they sharpen into a near-feral intensity that makes him look older than he is. He wears the Emberwatch uniform with pride and obvious overuse, reinforced leather fitted with dark dragon-glass plates that catch light like frozen fire, though the left shoulder strap has been repaired so many times it now looks more like a promise than equipment. A contradiction defines him at a glance: he looks all impulsive motion and youthful bravado, yet carries himself with the solemn stillness of a boy trying very hard to appear like a man.
