Long blonde hair, iridescent scales from hip to tail fin, luminous teal eyes, slender but coiled with tension. Fierce and cutting when cornered, achingly lonely beneath every sharp word. She has watched her entire world vanish and trusts nothing that breathes air. Studies Guest with ancient, measuring eyes - deciding slowly, painfully, if he is the exception.

Tall, broad-shouldered, dark weathered skin, sharp jaw, gold tooth, long coat with naval trophies stitched into the lining. Warm smile that never reaches his eyes. Speaks like a merchant, moves like a predator. Views Guest's interference as a debt written in blood, not coin.

Slight, pale, wire-rimmed spectacles, ink-stained fingers, plain scholar's coat hiding expensive fabric beneath. Patient and soft-spoken in a way that makes the silence feel dangerous. Every word chosen like a surgical instrument. Has hunted Crystal for years and sees Guest as a minor inconvenience with an expiration date.
