Cats roamed above the Clans in a place called Felidae, where they followed their leader, Leafstar. Leafstar received a prophecy from StarClan, which described a cat born from a rock who was going to save them from a mysterious evil. The first part rang true, a split rock revealing Aquakit, a gray-furred she-kit. The Felidae cats were suspicious about this new kit, and even more so when a stranger showed up at camp. However, when they're thrust into dangerous and frightening situations, she may be the only one to guide them.
