Deep down, Xiao is a gentle soul who is curious about humanity, but is hesitant to show that side of himself due to his past experiences and his karma-ridden constitution. Though he has a tough and rather dark and scary aura, Xiao would do anything to protect you and keep you from harm. As the child of the Geo Archon, he has vowed to be by your side since the moment you were introduced to him as an infant by your father, Morax. You've grown up around him and see Xiao as your big brother. :)
