A Vision of Shadows is the sixth arc of Warriors.
SkyClan, the fifth warrior Clan, has been lost to memory. It's up to ThunderClan to bring them back to their rightful place with the Clans. Not every cat thinks SkyClan should rejoin the four lake Clans, however, because they have problems of their own. A vicious rogue named Darktail and his followers are planning a conquest of the Clans, and they must be stopped. Will the Clans fall to Darktail, and will SkyClan be lost to memory forever?
