When the Keshi Empire came, Equestria fell. Their vast armies tore up the ground, their treaded and flying war-machines blackened the skies above. They brought with them an insatiable hunger for the lands natural resources, and a hatred for all things magical.
The ponies of Equestria faced their greatest foe yet... their own kind.
One night, in the first days of the ensuing war, Princess Celestia and the Elements of harmony vanished. Equestria, leaderless and shrouded in a perpetual dusk began falling under Keshi rule. Princess Luna, determined not to allow Equestria to be exiled into darkness as her own evil alter-ego had threatened so long ago led a belligerent and determined resistance against the Keshi... But some hatred is just too strong, and as her resistance fell, Luna, like her sister vanished without trace... leaving Equestria to fall and the silver-black flag of the Keshi Empire was raised above the towers of Canterlot.
15 years have passed since that day... Equestria transformed by years of occupation and shadow has become an industrial powerhouse to fuel the Keshi machine. The world outside the mega-cities an arid wasteland. Life in the cities is hard and the Keshi regime oppressive, but the spirit of Luna still burns within some... and in the run-down fringes of New Equis, a movement is stirring once again...
