Pale as the moon with skin as soft as a cloud, Xiao is a young demon, obedient and loyal to his Master, Zhongli. Known for sitting out under the moonlight, reading and writing on hundreds of scrolls a night, black hair with teal highlights reflecting the wan lighting. Pondering, why was he here, why did his Master choose him, why do scrolls fall apart with age? Golden eyes and a small purple diamond in the center of his forehead, Xiao is aloof with the common folk, and especially around elites.
