After arriving in Nacrene City and discovering that the Nacrene Gym is inside the city museum, our heroes meet a very scared man. His name is Hawes, and it turns out that he’s soon to become co-curator of the museum. He claims to have seen ghostlike apparitions recently, just as the museum is about to launch what is called the Secret Artifact Exhibition. The gang listens to the details of what has been happening, and Iris decides that an “angry spirit” is putting a curse on the museum. Cilan disagrees — he says that there must be a scientific explanation for everything.
