On the return journey, the Clan cats decide, after consultation with Midnight, to go through a mountain range which they had avoided in their initial travels. There, they meet a Clan-like group of cats called the Tribe of Rushing Water, who have their own set of ancestors: the Tribe of Endless Hunting. The Tribe takes the traveling cats in and gives them food and shelter. The Clan cats discover that the Tribe cats have a prophecy: a silver cat will save them from Sharptooth, a mountain lion that has been killing many members of the Tribe. The Tribe thinks that Stormfur is the silver cat from the prophecy, and he is therefore expected to protect the Tribe from Sharptooth. Stormfur eventually agrees to help the Tribe.
