This is an idea that wouldn't leave my head, inspired by Fairy Slayer's "Mommy Nearest," Aldea Donder's "Alicorn," SoundofRainfall's "Play" and RainbowDoubleDash's "Lunaverse"

Alternate Universe: Instead of Twilight Sparkle, Princess Celestia made Rainbow Dash her personal student instead! Follow her through the events of the 1,000th Summer Sun Celebration. A reimagining of "Friendship is Magic"

Twilight Sparkle starts to learn about gravity-manipulation spells after Princess Celestia sends her a book on the subject. Casting the spell is easy, but cancelling it, not so much, and Twilight soon finds herself without a hoof on the ground when she becomes the accidental target of her own magic.

On any other day, Twilight could deal with this. But with representatives from the prestigious Canterlot School of Magic due that evening to consider a possible annex in Ponyville, Twilight must find a way to be able to attend the event without revealing her foul-up.

Becoming an alicorn isn’t a reason to give up on friendly get-togethers. Brunch and a competition to solve the Manehattan Times crossword puzzle is a Sunday tradition for Twilight Sparkle, Cheerilee, and Mayor Mare. As the newest alicorn studies her developing magic, she will learn an unexpected lesson about the power of words.

Chrysalis has kidnapped Celestia, so she has Twilight Sparkle right where she wants her!

And Celestia really doesn't want to hear about it.

A bit of silliness that I wrote in about four hours, trying to get rid of a writers block.

As with every living creature, once every year, Princess Celestia has a day that commemorates the anniversary of her birth. Given that she is blessed with many wonderful friends and family members, she receives many gifts on her birthday. Some she likes more than others, while some are rather odd.

On this one thousand seven hundred and nineteenth birthday of hers, she receives a large stuffed squid plushie.

She is perplexed.

Years ago, two unicorn prodigies attended the same school without knowing it. One became changed by friendship at an early age--the other far later in life.

At a fashion show gone wrong, the two prodigies at last meet. Being who they are, it's impossible for them to resist comparing notes...

(REWRITE IN PROGRESS)

After a weekend spent in Canterlot, Twilight Sparkle arrives home to find an odd scroll in her saddlebags. In the following days Twilight is plagued by terrifying nightmares, and horrific visions from a life not her own. Can Twilight Sparkle resist the Nightmare, or will she fall prey to the darkness?

Scootaloo's life hasn't been the easiest. Being orphaned at a young age and brought up in the foster system came with its own set of challenges, not the least of which was a lack of older pegasi around to teach her how to fly. Fortunately, Rainbow Dash can help with that. With her honorary big sister taking a more active role in her life, Scootaloo learns much more about herself than just how to fly.

A story about love, family, and growing up.

Some accidents are small, and some endow you with the power of a godly ruler. On the opposite end of things, you lose your wings along with your ability to move celestial bodies, and you can't tell anypony. Why, because what would they think if the princess became a librarian? It's going to be "fine". Celestia just needs to switch back with Twilight before either of their true identities are revealed. All Twilight has to do is hold down the castle, fight off scheming villains, run the country, and worst of all... deal with all the noble ponies.

Rated teen for shenanigans and some more serious parts. Takes place at the end of lesson zero. Please tear this apart with comments. I like criticism. Comment if you have issues, don't leave me with a mystery thumbs down.

Canterlot... For centuries, Canterlot was the shining gem of Equestria, the pinnacle of pony society. Now, it’s a reminder, a bleak and monolithic warning to the world. 

Changed by the chemical and technological poisons that plague the mountain, an abomination of nature, I wander the greatest disaster Equestria has ever seen. 

... I will escape eventually, and when I do, I hope my friends still see me as Twilight Sparkle, and not the monster that hides among the ruins.
