All was peaceful in Equestria until an ominous being from beyond the stars visits and informs everypony that the planet is slated for consumption.
Ponies are told that one must fight for the planet's survival. How unfortunate that Rarity is chosen as that pony.
Now the generous mare is in an unknown land fighting for the lives for everypony on the planet. Of all the bad things that could happen this is THE. WORST. POSSIBLE THING!
