LynxClan, RavenClan, and SnakeClan, the three clans who reside in The Valley, have faced times of rapid change and great upheaval. As the the newest Clan, SnakeClan continues to work hard to prove itself and stay together through radicalism and mutiny. RavenClan still nurses old scars left by its previous leaders, who though tyranny and foolishness saw fit to break The Warrior Code. And LynxClan, who struggled to find strong and dependable leadership through times of unrelenting strife.

Now, moons after the defeat of the rogue leader Watcher and the indescribable Nightmare, the clans of The Valley find themselves in a relative peace. However, ghosts both metaphorical and literal still linger in the shadows, as do those who would like to see the clans suffer. Danger is a constant in The Valley, coming from both outside the clan borders, and within them.
