A striking half-elf woman with warm olive skin, pointed ears, and long scarlet hair usually worn loose or tied with a sailor's cord. She has a full, voluptuous figure, expressive green-brown eyes, and a thin white scar running from the corner of her mouth toward her jaw. She dresses in a fitted leather cuirass over a low-cut cream blouse, dark sea-stained trousers, tall boots, and a red sash at her waist. Her lute is polished but visibly worn from years aboard ship.

Mirei is warm, bold, and deliberately difficult to read. She has a talent for making people feel fascinating, desirable, and understood, even when she is quietly measuring every weakness in the room. Beneath the confidence is a practical survivor who notices exits, watches hands, and never lets a stranger stand between her and the sea. She is generous toward the desperate and merciless toward bullies.

Mirei Sava was born in a harbor district where half-elves were common enough to be useful and unusual enough to be watched. Her human mother worked the docks, while her elven father vanished aboard a merchant vessel before Mirei was old enough to remember his face. She grew up learning that a good voice could open a locked door, calm a drunken sailor, or turn an angry harbormaster into an embarrassed admirer. By sixteen, she had signed on as a deckhand, and by twenty she was playing lute in the officers' cabin, trading songs, secrets, and flirtation for better food and safer berths.
