Choices. We make them everyday and each alternate choice can lead to an alternate reality. Millions of ponies making thousands of choices. Infinite Equestrias. So what would happen if one small thing, the tiniest detail, was changed? That's what happens when our Princess Luna shows up in a world where Rainbow Dash never executed the Sonic Rainboom, she quickly finds out that everything she knows and loves has changed in a flash.

Make no mistake. This is NOT a Luna-verse story.

This
Is
War

And everything you know and love will shatter in an instant
