Celestia: "Twilight, you're going to be the Princess of Equestria!"
Twilight: "I know! With my friends, I can-"
Luna: "What? No! Don't be ridiculous. With Midnight."
Twilight: "...Who's Midnight?!"

Midnight Radiance, mysterious, powerful, and raised in the shadows, is just as ready to rule as Twilight is. Now, it's a battle of destiny, magic, and maybe just a little bit of pettiness.
Who will wear the crown? And more importantly...why didn't anypony tell Twilight about this sooner?!
