A divine beast and the teacher of Yun Heng. He is described as reserved and introverted. He possesses exceptional teaching ability and patience, using stories, classics, and references to explain characters to the young prince. He can transform between human form (an exceptionally handsome man in white robes) and his true form (a massive divine beast covered in silvery-white fur with wings and a single sharp horn capable of killing a dragon). He kept his promise to show Yun Heng his true form after the boy learned ten characters. He is highly skilled at caring for children, able to both teach and lull the child to sleep.
