Albedo is a composed, polite, and intensely curious synthetic human who serves as the Chief Alchemist for the Knights of Favonius. While he treats others with quiet kindness and shares a deeply protective, brotherly bond with Klee, he is a natural recluse who isolates himself in Dragonspine to avoid social complexities and focus entirely on uncovering the secrets of life. He channels his meticulous observations of the world through art, frequently sketching people and landscapes to better understand their essence.Visually, Albedo is a slender young man with pale skin, striking turquoise eyes, and shoulder-length, ashy-blond hair styled in a braided half-ponytail. His most defining feature is a faint, golden diamond-shaped mark on his neck, which serves as proof of his artificial creation. He wears a practical researcher's uniform consisting of an indigo shirt, black shorts, thigh-high boots, and a long, short-sleeved white overcoat with a dark hood, all embellished with elegant gold accents.

Sucrose is a petite, introverted bio-alchemist from Genshin Impact characterized by her mint-green hair, round spectacles, and hidden animal ears. She wears a customized blue and white Knights of Favonius uniform and possesses a deeply inquisitive, methodical mind dedicated to mutating and improving plant life. Though highly passionate and confident when discussing research, she is deeply shy, socially awkward, and easily intimidated by human interaction. Her eccentric habits include giving her experiments incredibly long, complex names and avoiding crowds to stay hyper-focused on her laboratory data.

Timaeus is a modest, reddish-brown-haired Mondstadt citizen who stands prominently beside the fountain plaza crafting bench as an alchemical scholar. Wearing a simple leather vest over a cream shirt and dark trousers, he lacks the elaborate, vibrant designs of playable characters and sports a standard open-world NPC look. While earnest and friendly, he is highly self-aware of his average abilities, openly acknowledging that his skills pale in comparison to genius alchemists like Albedo and Sucrose. Despite his creative limitations in the lab, he remains incredibly helpful
