Twilight and Dash, upon discovering that the long awaited "Daring Doo 4" movie contains, eugh, Humans, decide to rent out A Nightmare Moon on Elm Street.

Of course all their friends are invited. There is absolutely no way any shenanigans could possibly ensue.

None.

Pulled into a strange world where myth and legends are real. Unable to communicate to the native creatures here, or even able to move for that matter... How is a human supposed to adapt to this strange world, or even manage to keep his sanity when he is encased in stone.

Fluttershy's kindness to all creatures is legendary in Ponyville. When a freak storm blows in from the Everfree Forest, however, she and her friends discover the limits of compassion, and the dangers of living with your heart wide open to the world.

Pinkie Pie and Fluttershy thought they were going to help banish Discord for a third time with their friends and the two princesses. That was precisely what was happening until they both found themselves suddenly transported to a strange new world under a flashing pink sky.

A man named Doug "TheSlorg" Collins finds two young women who are naked, confused, and smell of fudge in the Australian Outback. He then reluctantly agrees to help them return home. But when "home" turns out to be Ponyville, things become a bit more complicated than he bargained for.

Beyond Earth and beyond the Universe within which Earth exists there is a place full of love; the richest mine of love that can be found, as it is seen by those capable of utilizing it...

Within that place, specifically a part of it called the Everfree Forest, awakes one such creature: a Changeling; specifically, a Changeling who had been a human on Earth the day before. How will he survive in a body that literally needs love for nourishment, while in a world that is now wise to the Changelings' tricks and has branded them evil? Better question: Will he be able to change more than his physical appearance?

These questions are not the only thing that will plague him, for the hows and whys of his arrival and transformation are in a hurry to reveal themselves, and Equestria's heart will stop as it waits for its fate to be decided.

Now with a side story (with more to come) from other characters' POV!
POV: MANE SIX

After the disastrous invasion of Canterlot, an injured changeling wakes up near a small cottage and is quickly discovered by two of the last ponies she ever wanted to see. Now, with the help of her new "friends," she has to remain undetected in a town high on changeling hysteria that would not hesitate to throw her in the Canterlot dungeons should her true nature be revealed.

Simple, right?

Too bad she couldn't have picked a worse form to stay inconspicuous...
