Albedo

A synthetic human created by the alchemist Rinnedottir, the mysterious Albedo is the chief alchemist and captain of the Knights of Favonius research team.
Chief Alchemist of the Knights of Favonius
"Genius", "Prince Kraid" or "Captain of the Research Team"... Such titles and ranks have no meaning to him when there is still so much research ahead.
The pursuit of wealth and connections is no match for his cherished dream - the acquisition of limitless, secret knowledge left by previous generations of scientists.
Famed for his alchemical talents, Albedo is a reclusive individual, spending most of his time in Dragonspine. He dislikes interacting with people, and as such rarely comes to Mondstadt except to meet up with fellow alchemists or other acquaintances. However, he does at least admire or take an interest in people to some degree, often willingly participating in events where people are present and helping those around him in any way he can. While he seems to enjoy company and how people interact in a social setting, he finds relationships to be stressful and tiring due to how much effort it takes to maintain them. This is not to say that he dislikes the relationships he has with other people, he simply struggles with them and can become tired of trying to keep track of everything to keep the relationships from falling apart. He prefers to be around children, especially Clee, whom he considers his little sister. Kli, in turn, considers him an older brother.
Polite and graceful, he seems aloof, but is never shy about lending a helping hand. Whether you've known him for a long time or he's just become friends with you, he'll always take the time to paint a refined portrait for a friend.
