Summary
''"This is nothing more than the calm before the storm, the skies ahead are darker than we could imagine. Who knows how long this storm will last?"

Dark skies have settled above the clans, with the looming shadows threatening to destroy the clans forever. With a disease ripping through ThunderClan, the race for a cure becomes even more desperate. Tensions are brewing between SkyClan and RiverClan, threatening to destroy the alliance that binds them whilst ShadowClan is hurling accusations, their leader greedy with power. And all the while, WindClan is ominously quiet.

With the divisions preparing for battle, this war suddenly seems much more real and an absolutely terrifying prospect. Battles will be fought, decisions will be made and the ultimate sacrifice given. One thing's certain; no cat can be trusted. ''
