They realize that Breezepelt must have been recruited by Tigerstar to help fight in a war between StarClan and the Dark Forest. Jayfeather receives a prophecy informing him that there is actually a fourth cat in the prophecy regarding him, Lionblaze, and Dovewing. Jayfeather initially believes it may be Mothwing, medicine cat of RiverClan. However, divisions between the medicine cats due to the accusation that Jayfeather murdered Flametail in Night Whispers makes it difficult for him to speak to Mothwing. Jayfeather is granted safe passage into RiverClan territory, however, and Mothwing shows him a reed that has been smoldering for days, even after a heavy rainfall. Jayfeather takes this as an omen to find the spirit of Flametail in StarClan, although the divisions in StarClan make it difficult. When he finds Flametail, he convinces him to reveal the truth: that he had drowned and was not killed by Jayfeather. This revelation resolves the divisions among the medicine cats, who then unite StarClan in preparation for the final battle with the Dark Forest. Former ThunderClan leader Bluestar tells Jayfeather that the fourth cat in the prophecy is Firestar. The final battle between the Clans and the Dark Forest then begins, with both StarClan and Dark Forest cats taking on corporeal forms. It's not long before the battle begins spin out of control. The battle ends when Firestar kills Tigerstar's spirit, and then perishes himself, making Brambleclaw the new leader of ThunderClan.
