He is an 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 mostly restrains himself from large crowds and social interactions. Due to the nature of his work, Xiao typically avoids humans. Not only does he think his bloody past makes him incapable of fitting in, human souls are less robust than adepti's and his karmic debt taints his surroundings.
