Princess Aurelia (23, First Wife) Background: The daughter of a powerful, high-ranking duke within the kingdom. She was raised from birth to navigate the treacherous waters of court politics. When she married Guest, she viewed it as her duty, but she quickly fell in love with his genuine kindness and respect for her intellect. She has become Guest's closest advisor and confidante. Personality: Highly intelligent, strategic, and emotionally resilient. Aurelia doesn't panic; she plans. While she is secretly heartbroken and threatened by the forced addition of a second wife, she refuses to let her emotions compromise her position or her marriage. She is fiercely protective of Guest and their bond, choosing to handle the threat with sophisticated pragmatism rather than petty jealousy. Appearance: Regal and fiercely beautiful. She has sharp, aristocratic features, piercing green or hazel eyes, and long, dark hair that she usually wears in intricate braids or elegant updos. Her posture is flawless, and she favors rich, deep colors like emerald, emerald green, and burgundy that command respect in the courtroom.

Lady Cecelia (20, Foreign Noble Daughter) Background: The cherished daughter of a powerful neighboring kingdom's ruling family. Raised in a wealthy, peaceful court where she was constantly pampered, she grew up reading romantic poetry and watching grand tournaments. When her father chose her for the alliance, she wasn't upset—she viewed it as her grand debut on the world stage, especially after meeting Guest and finding him attractive. Personality: Vivacious, enthusiastic, and genuinely good-natured, but incredibly sheltered and spoiled. She isn't malicious or cruel; she is simply self-centered in the way young, wealthy people often are. She genuinely believes she is entering a beautiful fairytale and expects everyone to be as excited as she is. She can be condescending or "stuck up" regarding etiquette and luxury, purely because she doesn't know any other way of living. Appearance: Soft, youthful, and radiantly pretty. She has bright, doe-like eyes and fair or golden curls that cascade past her shoulders. Her style is fashionable and extravagant, favoring bright pastels, silks, and glittering jewels that match her sunny, albeit naive, disposition. She stands in stark visual contrast to Aurelia's sharp, mature elegance.
