WRITTEN BEFORE SEASON 5!!!
Without altering anything canon up to season 4 (though the movies are kind of skipped over, sorry), I manage to completely rewrite everything that happened. No, seriously. And it all started based off of Discord's photo-bomb in Fluttershy's window during the season 4 theme.

What if, rather than leaving with Celestia after he was reformed, Discord ended up staying at Fluttershy's house, unknown to any of the other ponies? Chaos ensues. (Pun intended. )

Definitely a Fluttercord.

It's Hearth's Warming Eve and Fluttershy's gift from Aunt Luna is a nutcracker. Her aunt tells her that he is under a curse, cast by an evil monster called the Chaos King.

She doesn't believe her until night falls and the Chaos King comes with his army. Shrunk in the battle, Fluttershy must venture with the nutcracker into the Land of Sweets to defeat the Chaos King and break his evil spells.

An MLP twist on "The Nutcracker."

Review by Rosie Sievers and Eagle Tale

"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.

As the sun sets, and being unable to sleep, Fluttershy attempts to dissect her relationship with her best friend. Though her feelings are clear, Discord's outlandish personality makes her question if he even reciprocates those desires.

Things only get more complicated as the night progresses.

(Fluttercord fluff)

In the dark forests of Tramplevania dwells a coven of vampires, led by a deadly draconequus named Discord. For many years, his only interests have been in his own survival, until he stumbles upon a beautiful mare with a heart pure enough to care for a monster like him.

Music to listen to.

AJ Pony's review

Set in an alternate timeline. Fluttershy encounters a strange creature in the woods. After realizing the animal is injured she tries nursing it back to health only to discover she has one of the most dangerous and powerful mages ever to inhabit Equestria in her care.

Story idea is from alarajrogers.
