Through a series of astronomical events that even Stephen Hawking can't explain; the Equestrian universe and the universe we live in have collided, sending the Equestrian residents into our world. Through a series of political issues, the United States, and eventually the world, are thrown into a long and bloody war. The sun no longer shines, and a massive barrier is stretching along the East Coast, going from the bottom of Lake Superior to the Gulf of Mexico. It keeps the Equestrians out, and us safe.

But before the war, a Brony named Harry was suddenly in the care of six ponies who say they were forced here by magical means, and their ruler is in trouble. But once war broke out, the FBI was tasked with getting any ponies out from human lines, including Harry's ponies. Now, on a hellbent mission to save them, Harry enlists in the war to save his friends.

And you know what they say about war…
It never changes.
