Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

“My name’s Daisy Jo Martinez. I was born – or so my birth certificate says – on March 30, 2012. I’m married with two kids, my husband’s a Naval officer. I’m originally from a town just outside of DC called Winchester, Virginia – apple capital of America, yay, go me. I’m a Republican – that tends to shock a lot of people – and I’m a practicing Catholic – and that tends to shock more people than the first, and like I said, I’m married – I think people start passing out at that point. I've lived a happy, charmed life and I’m proud to be an American.

“And as you can also see, I’m a pony. Well, physically anyway."

The first main story of The All-American Girl Saga.

Twilight faces the thought of immortality with her usual aplomb: falling down into a ball of misery and confusion about her role, and what she will do in the eventual absence of her friends and family.

That is, until a much older Twilight Sparkle takes the time to talk to her.

Sunset Shimmer was vital to the defeat of the Dazzlings at the Battle of the Bands. Now a heroine instead of a villain, she accepts the mantle of leadership while struggling against her own past. Sunset Shimmer will extend a hand in friendship, which starts an adventure that will create far-reaching consequences for her friends on both sides of the mirror. This story begins two or three days after the conclusion of Equestria Girls 2: Rainbow Rocks.
