After the Friendship Games, Sunset feels it's time to return home.

Only when she gets there, Twilight's castle is nowhere to be found, Cadance just got her horn, and Princess Celestia is still calling the bacon-haired pony her prized student rather than a failed one. And just reliving her past isn't on the table thanks to a pair of wings Sunset seems to have sprouted upon her return to Equestria.

With Sunset being back before she's supposed to, will the world stay as harmonious and on track, or will everything go down in flames as Sunset has to deal with allegations that she's really a changeling in disguise, a nerdy stallion with blue hair that wants to be her coltfriend, a pretty pink princess in need of remedial magic lessons, and an annoying purple pre-teen pony that will absolutely not go to bed without first being read Starswirl's Complete Mystical Mysteries Compendium?

Only time will tell

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

Twilight Sparkle comes across a small, battered diary detailing a new form of transportation. While the research is sloppy and the notes incomplete, Twilight takes it upon herself to see that the ancient project is completed.

Of course, nopony said it would be easy.

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

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.
