What would you do if your hometown was attacked and enslaved by an unknown alien race and your friends were either dead or about to die? Freak out? Run for your life? Fight?

Twilight Sparkle finds herself in this situation. Luckily, there are ponies, who can support her and give her strength she needs. There is one one problem, though. She betrayed them years ago and left them behind.

But that's just it, the silly little war with an alien race, nothing the battle-hardened ponies can't handle, right? As it turns out, not exactly. Join the Mane Six and other cast as they plunge into the heart of millenium-long conspiracy and fight forces even higher than the Princesses themselves.

Oh, and did I mention the alien invasion? This is gonna be fun! - T.S.
