'' Warrior Cats: Omen of the Stars'' is the fourth [[MythArc arc]] of the ''Literature/WarriorCats'' series. Serving as a direct continuation of the ''[[Literature/WarriorCatsPowerOfThree Power of Three]]'' series, ''OmenOfTheStars'' aims to conclude the story of ''[[Literature/WarriorCats Warriors]]''. With the ultimate battle of good and evil looming, three cats must unravel the secrets of the past to save the clans from the most legendary villains in Warriors history.

Six moons after their sister Hollyleaf vanished, Jayfeather and Lionblaze are still trying to determine whether Dovewing or her sister Ivypool is the true [[TheChosenOne third]]. While on a mission to another clan, Lionblaze witnesses Dovewing display strange powers and realizes that she is the true third. While Jayfeather and Lionblaze train Dovewing in the ways of the three, Ivypool's jealousy allows the villainous members of the [[{{Hell}} Dark Forest]] to lure her into their ranks. While training there, Ivypool learns that the Dark Forest members intend to declare war on [=StarClan=]. As the clans crumble, all cats must choose between attaining their desires or saving the clans.
