343 years after The Great War ponies from the north spoke of a city, nestled in the valley of a great mountain chain. A city of gems and hard stone that existed before the war. The emergence of this city drew many unwitting ponies to their deaths. The Frozen North became a bloody savage place. Where ambient radiation or freezing temperatures sapped the life out of any who stayed too long. The snows ran red with the blood as factions battled for control of the impregnable city. What peace the New Canterlot Republic had brought to Equestria ended in the north. Every faction in the wasteland worth a damn made their own plans to own the city. Leading to the inevitable resurrection of dead tensions, and ancient blood feuds. Meanwhile... Two Enclave pegasi siblings have found temporary sanctuary in an seemingly abandoned Stable. They are forced to confront the repercussions of a defecting during a forced march north; called Operation Exudes. A plan by the council of elders to establish a permanent colony inside The Crystal Empire. When their uncle returns to ask for their help, a series of events is put into motion leading them into the front lines of a new era of war.
