Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.

This is a story about Rarity's hips.

(All good stories are.)

Some realize that Trixie is not the first to bear the title of The Great And Powerful.

Few realize that it is less a title and more a curse.

The one who kills The Great And Powerful shall ever after be cursed to become The Great And Powerful.

On a related note, Twilight Sparkle is having a very bad week.

It's been six months since Rarity and Rainbow Dash were married. It's been six months since Rarity and Sweetie Belle's parents passed away. 

It's been six months since Rarity and Rainbow Dash took in Sweetie Belle.

Winner of the Holiday Contest!

Now, this story deserved the Grand Prize. Everything good that could be in a story, is in this story. There’s hurt, there’s comfort, there’s awwww-moments, there’s ouch,ouch,ouch-moments, an ending that will leave you in tears for a good hour… And the unexpected little twists that, as a Rainbow fan, I absolutely loved. A fall? Addiction? Her fears of another; her fears of somepony else following in her hoofsteps? Beautiful.

Not related to any of my other stories. Published on my one-year anniversary here at Fimfiction!

Twilight’s Hearts and Hooves gift to Rainbow Dash is a journey through their dreams. They can do anything anywhere they want.

Rainbow Dash has rather a poor reputation when it comes to her workload. Everypony always thinks of her as the pony who takes three naps during daylight hours, and four on weekends, and always seems to be looking for something to do to pass the time. All of this is true, of course. But ponies seem to think this means that she must not ever get very much work done.

Can the weather captain for all of Ponyville really be as lazy as she seems? Is that the only explanation for Rainbow Dash's free time and constant napping?

The weather is a full-time job. Twenty-four hours a day, seven days a week. And the worst weather happens at night.

So weather ponies have strange sleeping habits.

Set before the events of the show.

Audiobook reading by My name is R on Youtube.

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.

This story is a sequel to The Enchanted Library

A routine visit to Ponyville's ghostly princess is interrupted by the unfortunate fact that Rarity may have a small (see: big) fever.

Small oneshot set in the universe of The Enchanted Library. Takes place aprox. sometime before chapter 7 of TEL.

Thanks to lillo for the beautiful art!!!

Winner of Tchernobog's AppleDashLight Contest.

Applejack, Twilight, and Rainbow Dash could never have been said to be ordinary ponies. So it really shouldn't be all too surprising that they've managed to lead unconventional love lives as well. Love lives that they might have neglected to tell their friends about.

But they’re not worried; the magic of friendship has taught them well, and they are confident the bonds they've formed with their fellow ponies will result in nothing but heartfelt congratulations and acceptance when they make their relationship official.

They are stupidly, stupidly mistaken.
