Clarisse also reveals that a missing stone is one reason the golem cannot get up. One stone is in her room, which Noah had given her before. However, there is another missing piece, and Clarisse realizes that this second stone is actually inside Noah’s body. It has been protecting him all this time using his mother’s magic. She asks for permission to examine it, and Noah reluctantly agrees, even though he feels uncomfortable.
