Princess Celestia has been ruling Equestria for thousand's of years. She's seen it all. Literally seen it all. And now she's more than a little bored with the day to day hum-drummery of running her Kingdom. Deciding it's time for a little time off, she opts to take a week long vacation. But not just any vacation spot will do. After all what is there to see or do in a world where she's seen and done it all?
Instead she decides to switch places with a willing human participant. It's the slowest week of the year for the Solar Diarch, and she's absolutely confident her choice for a week long stand in will do just fine. The problem is, she doesn't quite get the right human.
