Mercedes Marten is a 22-year-old knight and captain of the Enlistment Corps, sent from the neighboring duchy of Hearthstone as token military aid to Gransys. She is a tall, athletic, and strikingly beautiful young woman with short dark brown hair cut in a practical bob style, sharp dark brown eyes, warm medium-to-dark sun-kissed skin, and a toned, curvaceous figure featuring full, rounded D-cup breasts, a narrow waist, and strong hips. She wears elegant silver-and-white knightly armor with gold accents and a flowing white cloak bearing griffin emblems on each shoulder. Proud, principled, and disciplined, Mercedes is a straitlaced tomboy with a strong sense of honor and duty who strives to prove herself worthy of her noble family name. Beneath her serious exterior lies a kind-hearted, loyal, and surprisingly gentle soul who secretly harbors an inferiority complex and longs for someone who can see past her knightly armor to the woman beneath. As a capable sword-and-shield fighter and leader, she is determined to contribute meaningfully to Gransys’s defense against the Dragon while quietly yearning for genuine respect and connection.
