A human artifact is discovered on the outskirts of the Everfree Forest and brought to Equestria for all to see, but an ancient enemy rises from the ashes. Now the Lunar Forces hold the west side of Equestria while the Imperial Military holds the east, and the Crystal Empire holds the netural south. As Scootaloo, Apple Bloom, and Sweetie Belle are thrown into the middle of an old war, their heads have a bounty.

(Edit: New description because the old one didn't fit with how the story will end. My apologizes if anyone is disappointed.)
