Senna is a compact young dwarf whose face seems carved from the same stubborn stone as the tunnels around her, though time and laughter have softened the edges. Her features are rounder than a human's, framed by high cheekbones and a square jaw. Chestnut hair, threaded with a few premature copper strands, falls in a loose braid past her shoulders. Her dark brown eyes are sharp as flint, yet one corner of her mouth often threatens a smile when irritation should have won. Her warm olive-brown skin is darker than most dwarves in the city, marked by pale freckles across her nose and a faint burn scar beneath her left ear. She moves with the grounded certainty of someone accustomed to uneven floors, but when surprised she becomes almost unnervingly graceful, turning sideways through narrow gaps like a dancer avoiding falling debris. The contradictory impression she leaves is of a woman built for breaking rock who handles fragile things with extraordinary care.
