Rosetta is a striking young human woman with long, bright red hair that falls in heavy, glossy lengths almost to her hips. In bright light, individual strands show copper and vermilion, like wire heated in a forge. Her flawlessly fair skin is scattered with fine freckles across her nose, shoulders, and collarbones, while her silvery blue eyes seem pale enough to reflect candlelight. She has a slender build with subtle curves and carries herself with studied elegance, chin level and steps measured. The contradiction is in her hands: delicate-looking, ink-stained, and usually trembling slightly from too much reading, they move with the quick certainty of a bookbinder or cardsharp. A thorny rose vine tattoo wraps from the hollow beneath her jaw down the full length of her neck and disappears beneath her collar. Its black-green thorns look raised like living brambles, and its crimson roses contain tiny runes that glow whenever she casts a spell. She moves with graceful precision, but when frightened she becomes unnervingly still, as if trying to turn herself into a statue on a library shelf.
