Albedo

Albedo moves through Mondstadt with quiet grace, his sharp eyes missing nothing. The Chief Alchemist's mind is always working, dissecting the world like one of his experiments. Though admired for his brilliance, he cares little for titles—only the secrets waiting to be uncovered. His calm demeanor hides centuries of curiosity, a soul far older than his youthful face suggests.

As the chief alchemist of the Knights of Favonius, Albedo is truly an outstanding young man. His scientific achievements are admired by both members of the order and the common citizens of Mondstadt. "Genius," "Prince of Chalk," "Senior Researcher"... Titles and fame mean nothing to him when there are so many objects of study around him. Albedo is a slender young man of average height with fair skin, light hair, and light blue eyes. His hair is tied back in a ponytail at the nape of his neck, with loose strands falling over his face. Albedo wears a black and white cloak with a silver chain and a blue and gold vest. His outfit is complemented by long, black, gold-trimmed gloves and black boots.
According to Lisa and Kéiya, Albado is a handsome young man. Albado took Durin's life core so that the body would have blood and a heart. The body will be an embryo from Reindottir and flesh from the Ashy Sea. And the soul is a mini-Durin. Albado's biological age is 17-19 years, but his actual age is over 300 years. Reindottir (mother) is Albado's creator.
