On secret assignment from Princess Celestia herself, Twilight investigates a powerful magical artifact for clues to the mystery of Luna's transformation in the evil Nightmare Moon. Incautious use of the artifact sends Twilight hurtling back in time. Can Twilight discover what caused Luna's transformation? And will she ever make it home again?

After the Changeling's failed attack, a full-out crusade is set against them. Many find a way to simply slip away. One is hapless enough to fall into the hooves of those his kind fought against. The changeling is promptly sent to the only pony Celestia could trust with such a thing.

Completely revamped, and thanks for constructive criticism and support behind the scenes (you know who you are, people).

Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Thanks to CedricBale and noobie56xx for tracking down the name of the artist so I could give them credit.

Twilight Sparkle isn�t dead.

But she's not exactly alive either, and there�s only one pony who can see her, can hear her, can prove that Twilight still exists. Unfortunately for Twilight, or perhaps fortunately, that pony is a certain pink baker and party planner.

Just before leaving for her honeymoon, the newly-married Princess Cadance finds her old diary in her clothing dresser, filled with memories long forgotten, where she then recounts on those happy days as Twilight Sparkle's foalsitter. (Featured on EqD!)

Update: The story is edited into a proper read without many of the horrors I originally put into it. Enjoy the ride!

Deciding he could be given another chance, Luna and Celestia come to an agreement to release the Chaotic God from his rocky imprisonment, locking his powers with a powerful spell. Magicless and with a chance at redemption, Discord's ways seem less chaotic than ever.

He does cause a lot of chaos though, to the faithful student of Celestia, who had eagerly taken over the task of watching over and teaching Discord by giving him a home under her own roof, in the process hoping to learn more about his species, powers and motives but surprisingly learning much more about both himself and her head... Which puts her in pretty amusing situations most of the time.

An adventure of a silly one sided (???) love and a look into the heart of Twilight Sparkle.

Twilight Sparkle may believe in Pinkie Pie's myriad abilities, but when an opportunity to study them from a perspective she never thought possible arises, how can she resist the chance at the understanding she's always truly wanted? More importantly, can Ponyville survive the trade-off necessary for this opportunity?

Twilight's years at Celestia's school were far from ordinary. Here are the challenging trials, dangerous spells, and important lessons that made her the mare we know today.

When dark creatures begin appearing in Equestria, Princess Celestia and Princess Luna summon the bearers of the Elements of Harmony to Canterlot. Before the six ponies can arrive, though, four strange ponies are expelled from a portal that appears in the throne room, and they explain that Equestria is not the only place at risk from these creatures. Thus begins an adventure that will reveal a greater destiny for Ponyville's librarian than she could have ever dreamed of.

Kingdom Hearts/My Little Pony: Friendship is Magic crossover. Pairings undisclosed.

Twilight Sparkle receives a letter from Princess Celestia. As a reward for her and her friends diligence in sending friendship reports, they will be treated with a trip to Manehattan to see a show. On their way to the 'city that never sleeps', Twilight senses that something is going on behind the scenes, a lingering trace of familiar magic is in the air, one that she feels is connected to everything. One thing is for sure. This isn't a simple vacation.
