Deep within mountains, forest, and marsh live four Clans of cats. All surround a large lake, that holds a small island.
Times around the small lake have been peaceful. All the Clans worked together through the last few hard moons they had endured.
This is until a prophecy a StormClan medicine cat receives, threatens the peace the Clans have enjoyed. All centering around a certain, great warrior, a terrible secret, and a litter of four kits that is abandoned in the StormClan territory.
As darkness digests the forest piece by piece, the Clans fear for the worst. The prophecy doesn't seem to be coming true as the cats thought, casting shadows on the Clans trust of their ancestors.
The Clans scramble to piece together what little understanding they have of the prophecy in order to protect themselves.
In hard times, where the Clans must work together, they are pinned against each other. Even against kin from their own Clan.
