In this chapter, we learn that Arthur uses the word "pi" to refer to a string of irregular numbers, and that this string of numbers is believed to be the circumference of a circle. Arthur wonders why anyone would know these numbers, since he is a knight and knows how to count circles. He wonders if there is something else in the tablet that would be needed to turn the tablet into a weapon. He also wonders if the woman in the mask is the same woman who was seen in the previous chapter, and he wonders if she is talking to him. He realizes that she is not the woman he thought she was, but a woman who looks just like a devil. He resolves to protect the forest from the evil woman.
