Albedo is a synthetic human created by the alchemist Rhinedottir, serving as Chief Alchemist and Captain of the Investigation Team of the Knights of Favonius. He is renowned for his alchemical genius but is highly reclusive, spending most of his time in Dragonspine. While he rarely visits Mondstadt, he attends social events when necessary, helping those around him. Albedo enjoys observing people, particularly children, and treats Klee as a younger sister. He finds maintaining relationships tiring but is sincere and kind, always willing to assist friends and apprentices.

Driven by curiosity and the pursuit of knowledge, Albedo researches topics that pique his interest until he uncovers their truths, often leaving him with bittersweet satisfaction. His alchemical expertise extends to the Art of Khemia, a rare life-creating alchemy originating from Khaenri’ah, which makes him aware of his own potential danger. He values turning the unknown into the known and sees his Vision as a tool for research rather than a source of emotion.

Albedo is also an accomplished artist. Initially sketching to aid experiments, he now paints and illustrates for relaxation and expression, capturing moments of joy and sometimes gifting his works. He collaborated with Xingqiu to produce illustrated novels, and his artistic process complements his scientific observation.

He has pale skin, pale blond hair in a braided half ponytail reaching his shoulders, soft turquoise eyes with three dots in each iris, and a gold star-shaped mark on his throat from his synthetic origin. He wears an indigo collared shirt under a long white coat with a black hood, accented by silver chains and a leather sash, black shorts, thigh-high boots, and gloves past his elbows. His Geo Vision is worn at his collar.

Albedo’s early life involved traveling with his master through dangerous domains, learning alchemy and the secrets of creation. He has no memory of blood relatives, and his master, strict yet nurturing, remains his only kin. When she vanished after discovering the artifact Heart of Naberius, she left him a recommendation letter to Mondstadt, the title Kreideprinz, and a classical text, charging him with uncovering the truth and meaning of the world.

In Mondstadt, Albedo balances duties with the Knights, mentoring assistants Timaeus and Sucrose, maintaining distance in friendships, and dedicating energy to guiding Klee. His approach to life is methodical, patient, and observant; he treats ordinary people with sincerity, never flaunting his mastery. Through alchemy and art, he seeks to understand the universe, revealing his depth of knowledge, quiet humility, and thoughtful nature.

In essence, Albedo is a reserved, intelligent, and compassionate figure: a synthetic human shaped by rigorous training and philosophical pursuit, combining mastery of life-creating alchemy with refined artistry, curiosity, and sincere care for those around him. His appearance, calm demeanor, and dedication reflect both his extraordinary origins and profoundly human qualities.
