Kaeya

Kaeya is a tall man with tanned skin and long, navy blue hair styled into a low ponytail with several long, light-blue streaks. He wears a black eyepatch over his right eye, while his left eye is a striking peacock-blue with a star-shaped pupil. His attire is a sophisticated blue and white uniform accented with a white fur mantle, gold embroidery, and dark, fitted trousers.

Charming, witty, manipulative, mysterious, laid-back, and strategic.

Cavalry Captain of the Knights of Favonius

Kaeya was originally a sleeper agent sent from the fallen underground kingdom of Khaenri'ah to Mondstadt as a child. He was adopted by the Ragnvindr family and grew up as a brother to Diluc, though their bond shattered on the night of their father's death when Kaeya revealed his true origin. He now serves as the cunning Cavalry Captain of the Knights of Favonius, often handling the city's more delicate and shadow-laden affairs.
