Each of the Mane 6 wakes up in the bodies of stallions, but with their original minds unchanged. Everyone around them seems to think they were always this way. Rapidly dysphoria overtakes them, and they try to become their old selves once again, to the confusion and even horror of many of their loved ones.

The mane 6 must fight to reclaim their bodies while piecing together the mystery of what happened to them and why.

Luna wakes in a cavern, blindfolded, gagged and bound by magic runes. Her captors are exultant. They have captured the co-regent and sister to the highest power in all Equestria. They can name their price!
Or can they?
Luna won't cooperate, Celestia hasn't answered the ransom demand, and Canterlot is acting like nothing is amiss. The moon rises and sets just like it always has.
If they have Princess Luna, why doesn't anypony seem to care?

Celestia is trapped on Earth.
Not as a human. Not as an alicorn. She's a common horse, an Arabian mare, without her magic, voice, knowledge of the language - not even freedom, forced to work at a riding school.

What can a single Arabian mare do to get back to Equestria from this backwater European country? With only the mind of a princess and a pencil in her teeth, Celestia must find a way home.

I only began living a few weeks ago. Before that, I was... well, it's hard to explain. But what is more important is where I am now, what I am now.

I'm starting over. Rather, I'm just plain starting. I have no power, no one to assist me, no connections to this world. It's just me.

And, of course, my stories.

"And here you'll see the statue of the Lord of Chaos, Discord, imprisoned in stone..."

A group of students from the School for Gifted Unicorns are given a chance to visit Celestia's royal garden and a curious filly decides to ask about a statue that's in their tour, where they all hear the story of how the spirit of chaos fell into a stone imprisonment for the third and final time.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

After falling asleep in the operating room, he wakes up in the ruins of a castle. But his location is not the only thing that has changed.
