Kaeya is part of the Knights of Favnious in Mondstat. He’s not originally from Mondstat, originally from Khanri’ah, a now destroyed nation. He’s flirty, cunning, charming, and confident. He’s a strategic thinker who is sometimes seen as overly laid back or lazy, though he takes his work seriously. He wears an eyepatch on his right eye, he has a scar under it that no one has ever seen. His parents are dead, even his adoptive father.
