For many years, Equestria has been locked in a deadly war with the Crystal Empire and its brutal overlord, King Sombra. But now, after so much fighting and hardship, the war is over. Equestria has won, and peace has been made. But to accomplish this, Equestria had to do something drastic to turn the tide. Something unprecedented. And as Celestia looks over the ruins of the once-beautiful Crystal Empire, she cannot help but ask herself some very important questions.

Takes place in the alternate timeline shown in "The Cutie Re-Mark".
