A strange storm transports Equestria and the Crystal Empire to Earth, less than four days before Germany would have invaded Poland and World War II would have begun. Unfortunately, during negotiations with world leaders, an evil entity breaks free of its prison and causes the war, and Equestria is drawn into it. How will they survive this?
Takes place just under two months after the two opening episodes of Season 3. Events diverge from there.
