Warrior Cats.

There is really no plot to this story. We just go with the flow, and see what happens. You can make your own characters and everything.

A low rumbling noice erupted in the distance. Waves lapped up onto the shore in an unbreakable rhythm. Standing at the edge of the coast, a gray cat stared out into the horizon beyond the water. The rumbling noise grew louder, and seemingly closer as the cat stood there.
“I.. I don’t understand. What is that noise?” The gray she-cat mumbled. Her fur bristled as she listened to the terrifying sound.
A black cat pressed her flank against the gray cat’s pelt. “Great trouble is coming, Mistystar.” The she-cat rasped as she sat down, curling her tail around her paws.
“What is it, Blackfeather? What is coming?” Mistystar turned her gaze to the StarClan warrior, but she was fading into a soft wisp of air. “Wait! Can’t you tell me what the trouble is?” She called to the vanishing cat.
“Mistystar..” A muffled voice started, “The earth will open and spread afar, causing blood and death on the land…“ The voice faded and Mistystar looked up at the sky. The rumbling sound was becoming louder every heart-beat. A prophecy? What could it mean?
