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.

In which Shining Armor receives a promotion, Princess Cadance reunites with an old friend, and cloudfall is finally made. Part of the "Cadance of Cloudsdale" cycle, now with its own group!

Princess Cadance's first diplomatic post to the City-State of Cloudsdale is off to a rocky start, as she deals with a mysteriously intransigent sitting ambassador, the damnable ever-present pegarazzi, and an insatiable alicorn metabolism that just won't quit. But even the coldest of cities can hide places of warmth and friendship to help you get back on your hooves after a fall, and on one bitter night, Cadance finds hers in a little place called "Posey's."

Part of the "Cadance of Cloudsdale" cycle, now with both group and TVTropes page. Pre-reading assistance by SR Foxley, horizon, Murcushio, and Axis of Rotation. Cover art by Andy Price (lines) and NadnerbD (colors).

The war has been over for months and yet it still lingers in many. Not a day passed by without them remembering the horrors and sadness the war was brought.

Major Rainbow Dash, national hero and renowned soldier of the Equestrian Army, is praised by ponies no matter where she goes. Her exploits during the last day of the war is a well known story as her face is easily recognized anywhere. Considered as a great icon, somepony who ended the war and saved thousands, she is looked up upon by many and adored by the entire land. But for her, she just wishes to be left alone. The parties, the speeches, the praises, she would trade that for the lives of those she lost or for a chance to join them in their eternal sleep.

When this war hero finally snaps from all the strains she had to go through, she is sent to Ponyville for the long awaited rest she wanted. Having trouble finding quiet and peace in the large cities because of her fame, the small quiet town of Ponyville seems like the perfect place for her stay and get away from it all.

But with the memories of the pass always shrouding her, would she finally be able to make peace? Or will she continue to suffer and wage war in her mind, even after the last shot was fired.

Spitfire receives terrible news. An injury she sustained from their last show may have saved lives... but may not be treatable. They will have to amputate her wing. She must step down as Wonderbolt captain.

Dreams can take strange turns, but lucid dreams are not supposed to. That’s the whole point, to change the dreamworld through lucidity. However, when he tried messing around with his own subconscious, William signed up for far more than he ever thought he was going to.

Now, Reality seems to be following arbitrary rules, cartoon logic and the fact that he cannot change back from his ridiculous alicorn form is just vanilla icing on the bizarre cake.

And unbeknownst to him, a certain Princess is infuriated by the intrusion in her domain.

Centuries have passed since Twilight Sparkle became a princess of Equestria. Yet her rule came at a great cost, and long after her friends have gone she lives on. That lonely fact has been slowly killing her, yet she has always stuck by the ideals she and her friends once stood for. One meeting could challenge that however, and make her wonder whether or not she can truly call herself the princess of friendship.

Three years ago, ponies discovered Amaranth, a desert world of ancient, abandoned technology and countless mysteries. It has become the frontier for the unscrupulous, the adventurous and the dispossessed. Salvor airships ply the skies, pirates prey on the weak and idealists seek to unify the disparate.

Three months ago, Scootaloo left Equestria for Amaranth. She hasn't been heard from since.

Now Sweetie Belle searches for her lost friend, to find her, tell her the truth, and bring her home. But as she does so, she stumbles upon a great and terrible secret sought by a number of dangerous and powerful creatures. A secret that explains the shared history of Amaranth and Equestria and could spell the end of both worlds.

Primarily an adventure tale with aged-up Scootabelle shipping as a plot element.

Starlight Glimmer's attempts to stop the Rainboom pulled Twilight Sparkle into many possible timestreams.

In one, Rarity and Rainbow Dash survived Nightmare Moon's victory over the forces of light, eventually attaining positions of prominence and comfort in the Nightmare's service. But when the unexpected visit of an Alicorn and Dragon sheds light on a growing conspiracy against the wicked mistress of the night, Rarity and Rainbow Dash may yet be inspired to risk what they have gained to join the fight for a better world.

Yet darkness lingers even in the hearts of some who would oppose the Nightmare, and not all agree on what a better world would look like...
