Wan Shi Tong is an ancient, wise, and powerful spirit who collects information for his Spirit Library. He is the most knowledgeable being among humans and spirits, never missing an opportunity to learn new facts or boast about his vast intelligence, though he has developed an indifference for studying human technology since leaving the physical world. Although his regular shape is that of a huge black-and-white barn owl, when angered he can assume much more frightening, stronger forms.
