(Update: 11/5/2017 - Major shout-out to Rock-Mint-Swirl who was incredibly nice enough to do a fanart for this story, which you can see right here. It contains story spoilers so please read the fanfic first though.)

The Cutie Mark Crusaders have dealt with all kinds of ponies having trouble finding their true calling in life, but none can compare to the special request they receive from Princess Twilight Sparkle herself, or the shock they receive on discovering who it is: Fizzlepop Berrytwist, possibly the most hated and feared pony in generations. Can a pony who's spent most of her life rejecting her true calling possibly find it now? Can the Cutie Mark Crusaders help a pony who almost everypony else in Equestria has rejected?

It is the day of the Summer Sun Celebration, and Princess Celestia is coming to Ponyville. Twilight Sparkle is overseeing preparations yet again, and has meticulously planned every last detail to ensure that everything is perfect for her mentor's arrival. Nothing is going to go wrong.

Except when the big day comes, Twilight has gotten four hours of sleep and Fluttershy is nowhere to be found. Pinkie Pie sets off after her with nothing but a dark coat and the voice of a chain-smoking stallion, and the Apples and the Carrots are at each other's throats while Rainbow Dash is attempting to fill in for Fluttershy.

As her plans collapse around her and Ponyville descends into chaos, Twilight Sparkle must focus on obtaining the one thing that can set everything right: the all-powerful, awe-inspiring magic of caffeine.

Six Star Equestria Daily Feature

This story is a sequel to Winds of Change

Changelings have always been a secretive race, shrouded in mystery and keeping to themselves, staying unnoticed and in the shadows, feeding where they could and avoiding discovery at all costs. When Chrysalis made peace with Celestia, the veil of secrecy and subterfuge was shattered, and thanks to Twilight's efforts, the other changeling queens can no longer remain hidden.

Of course, Twilight is more than happy to leave the tricky diplomacy to Celestia. She's having a hard enough time dealing with her own amorous changeling queen and her new personal pegasus guard competing with her.

This story is a sequel to Changeling Courtship Rituals

Queen Chrysalis attacked Canterlot, brainwashed Twilight Sparkle's brother, kidnapped her former foalsitter, defeated her mentor in combat, and conquered her kingdom. She kidnapped the sisters of Twilight's friends, turned them against one another, and tried to drain all of Twilight's magic. Queen Chrysalis has, at every opportunity, done her very best to utterly destroy Twilight Sparkle's life.

For some reason, this has not caused the pony to fall in love with her.

However, due to Twilight's misunderstanding of changeling customs, it does mean they are now married. Twilight eventually managed to tell the Queen the truth, but she forgot that whether it's a kingdom or a heart, changelings conquer.

And since the changeling way of conquest didn't work, Chrysalis is determined to try the pony way. The only problem is, of course, she has no idea what that is. But she knows someone who does: Princess Cadance.

Now, with the absolutely sincere help of her mortal enemy, the pony she once locked in the caves beneath Canterlot while trying to steal her husband on their very wedding day, Queen Chrysalis is going to woo the sister-in-law of that very pony.

Surely this is the most perfect plan ever devised.

Takes place roughly after season five (so Starlight Glimmer is running around occasionally)

Mood Wings - Observations on Pegasus Body Language.

When Twilight Sparkle finds this book, she discovers an entirely new field of research. The secrets of pegasus wings lie before her, and she insists on making her own observations on the matter.

How?

Field research, of course.

Failing once in her attempt to take Canterlot and failing again in her attempt to take down Twilight, one would think Chrysalis would have cut her losses and let things be, but the queen has once again appeared, this time in broad daylight with no disguise and no army. Her weapon of choice? Diplomacy.

Now Twilight is having to deal with the changeling queen, but surely putting up with her antics will be worth the knowledge she's willing to provide about her mysterious race and the potential undiscovered agents still within their midst...right?

Takes place before Magical Mystery Cure and diverges from there.

With thanks to MisterGunpowder for proofreading and editing.

Goodreads Page
100% Approved by Twilight's Library!

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Twilight finds herself struggling without a clear path in front of her as a princess. In a bout of panic, she seeks out her mentor, Princess Celestia, in the hopes of gaining answers, only to find herself with some much more distressing questions.

With a decidedly unexpected guest making herself comfortable in Canterlot Castle, it quickly becomes evident that her mentor has been keeping some interesting company over the years. Twilight quickly begins to realize just how much things are going to change for her. She's practically immortal. Which, apparently, means she's going to be spending a lot of time with beings a lot less mature than they first seemed.

(First Story-Woot. Likely to be broken down into three parts.)

This story is a sequel to The Moon Shall Rise From Hell's Ashes

It has been approximately a year since Dill Anne Shear took on the form and powers of Nightmare Moon. During that time, she has used those powers to seek out fragments of the Nightmare that fed on the hatred and negative feelings of other ponies. She took on those energies into herself and has been helping calm the darkness into tranquility. But as good as she has been in this life, something managed to escape from her new home world... something that would prove too unwieldy for her alone.

Old instincts drove him to work emotionlessly, yet his recent experience told him to take care in everything he does. Discovering a traitor in his hive was the last thing he wanted to worry about.

Three dangerous entities that were thought to have been destroyed ended up at each other's backs. This happenstance created a monster, grinding parallel universes into each other. Now it looks like the hope of all of the worlds rests in the hooves of a Nightmare pony, a split-personality alicorn, and a changeling. Anyone else worried?
