Hundreds of years ago, a pegasus by the name of Snaketounge decided to leave Equestria, striking out North with his followers. He settled on the Northwest border of Equestria, founding Disharmonia. The two lands have always known peace.Until now. With a sudden series of blitzkrieg attacks, Disharmonia has pushed deep into Equestrian, cutting a bloody swath through the once peaceful countryside. As the the forces approach Canterlot, intent on the destruction of the capitol, and the killing of the princesses, one obstacle stands in their way: Ponyville. Led by a deserter of the Disharmonian army, the brave ponies lead a last defence against the enemy. Can they hold long enough for the combined forces of the Griffon lands and the Crystal Empire? Or will they be crushed, and the everlasting Equestrian empire stomped out by an ally, turned nemesis?
