Celestia, Princess of the Sun and Princess of Equestria, has led a long life. She's made a lot of decisions, for good and for ill, and she's decided it's time to quit. Twilight Sparkle, her faithful student and fellow Princess, will assume the crown and rule Equestria in a month's time with the help of her friends. But before that can happen, Celestia has to host one last Grand Galloping Gala. She decided it would go out with a bang.

That was last night.

Today, the Princess awakens with a ring on her horn and a strange earth pony in her bathroom. She's hungover, and the pounding in her skull triggers some memories of events she pushed far out of her mind for many years. Because Princess Celestia wasn't always a Princess or even Celestia.

And her new husband won't stop running his mouth.
