Something bizarre has come over the land. The kingdom is deteriorating. People are beginning to act strange… What’s even more strange is that people are beginning to see dragons, which shouldn’t enter the world of humans.

For the witch Kumo this is a perfect opportunity. She can use the boy’s “fears” against the very one who would help him, Ged.
