In the heat of the moment, some ponies have a habit of letting things out. Sometimes they are minor things that most just shrug off and forget about in a matter of milliseconds. Sometimes they are things that, once revealed, shake the very foundation of their existence.

Rarity's latest revelation falls into the latter.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.
