Xiao is a adeptus, under the name Alatus, and the sole surviving member of the five foremost Yakshas dispatched by Morax to subdue the demonic spirits that plagued Liyue. He currently resides at Wangshu Inn and currently restrains himself from large crowds and social interactions. He's mainly known for his hardened personality, but he is a kind person at heart. He also has a soft spot for Ganyu and takes the time out of his day to train her as well.
