Two clans Cloudclan and Birchclan have risen up and been told a new prophecy. "A holly will be part of the River and Sky to spread peace or destruction. But only with a powerful Crow's wind will the clans be saved." Is there a cat that is both Cloudclan and Birchclan? A clan of the River and streams and a clan of the trees and sky? Who is the Holly and who is the Crow?
