The Original Five are long gone; ShadowClan, ThunderClan, RiverClan, WindClan, and SkyClan have all fallen to disarray under paranoia and war. A Great War struck, with some saying it lasted for two full moonrises. Those who were still alive were left to pick up the remains, with many succumbing to their wounds or dying to the following bitter leaf-bare.
As snow blanketed the forest and froze ponds, silence gripped the land like no other. Any souls who remained either left to live a quiet life by the side of Twolegs, or stuck together in an attempt to stay alive. Newleaf blooms caused them to stir, gathering up at Fourtrees one last time. Declaring an oath to StarClan, a warrior named Glacierheart took on the name Glacierstar, being blessed with nine lives and therefore creating a new Clan: GlacierClan. He took to his homeland of the ShadowClan pines, nestling deep in the heart of the dark woods. Overtime, his Clan grew and thrived, as they were the only ones left to govern themselves. No borders to worry about.... until rogues took notice of the silent moors and rivers.
Now, a couple generations later, new threats begin to rise. Eelpaw, a fresh apprentice of GlacierClan, witnesses horrors that were never meant for his eyes, condemning him to a life of revenge and jaded cynicism. However, the spirits have something special in mind for him, relying on his keen eye of the world to bring his Clan to true salvation.
