Twilight Sparkle has mastered many skills: friendship, magic, diplomacy, organization, and so on. However, Princess Luna has realized that Twilight has yet to master one final skill before she can truly ascend to the throne.

And so, Luna takes it upon herself to teach Twilight THE TRADITIONAL ROYAL CANTERLOT VOICE.

Twilight Sparkle discovers that the alternate timelines created by Starlight Glimmer in her misguided attempt at revenge did not, in fact, disappear when the original timeline was restored. Instead, they persisted as separate, parallel universes.

Never one to leave a job unfinished, she decides to employ the magic of friendship to restore those universes to a more harmonious state.

She begins with Nightmare Moon.

This story is a sequel to Sharing the Night

Twilight Sparkle is the alicorn of the stars, and after a period of self-discovery, ancient-goddess-discovery and a minor case of malmanifestation madness, she has finally come to share the night, a city, her ex-villain status and a bed with Luna, the alicorn of the moon.

Things are looking pretty good for her.

The five demigoddesses she created out of spite? Not so much. Celestia and Celestia are a little lost too, and for some unknown, completely mysterious reason, dragons are flooding into Equestria—and they're not acclimating. Someone probably should do something about that.

It never gets dull in Ponyville, does it?

TV Tropes

Twilight just wants to sleep; unfortunately for her, not only is Celestia in a playful mood, but Luna is itching for some quality time. Shining Armor and Cadence then show up, and it turns into tug of war with Twilight as the rope. The prize? Spending quality time with everypony's favorite purple alicorn.

This story has Twilight/Celestia and implied Twilight/Luna. Also, Cadence has a very... vivid imagination.

Now a plotless(okay, so there's a bit of plot. Just a smidge, though.) ball of comedic fluff with multiple chapters.

Chapter 1 - Say It - edited by ultra1437

Due to an unusual lapse in communication, Twilight and Rainbow Dash travel to Canterlot only to discover something sinister may be unfolding within the castle walls. A mysterious horror awaits. Something different. Comments always welcomed and appreciated.

After almost a thousand years of banishment, Luna has plans. Plans for how she will avoid being banished again once she's free, plans for what she will do to the sister who banished her unjustly. But plans can change, especially when a certain newborn Unicorn enters the dreaming for the first time.
This story has been rattling around in my head for a long time now and I hope I end up doing it justice. It's mostly influenced by the early seasons of the show and older stories, with very little draw from the newer seasons. I aim to take that inspiration and weave it into something resembling a fantasy novel.
chapter one is already done and chapter two is almost there, both will be released in the next few days, after that I'm aiming for at least a chapter a week.

Applejack is in love.

Having fought against her desires and hidden her sexuality for far too long, Applejack comes to terms with the prospect she has fallen hard for a certain young princess she believes is way out of her league.

What will she do?

This story is a sequel to About Last Night

One month ago, Twilight Sparkle and Applejack got drunk and then got married.

Now Twilight's a princess, and the pair have to work on integrating that new aspect of it into their relationship. Add to that Spike's feelings on the matter and the fact that he's getting the attention of fillies his age, and Fluttershy and Rainbow Dash's relationship, maybe they're better off grabbing a few more drinks...

While checking the ward spells in her palace's library, Cadance discovers a strange letter sent to King Sombra by someone she didn't know existed, from a nation that never existed. The search for answers sends her and Twilight, along with their friends, on a journey to uncover certain secrets of the past, only to realize that secrets abound in the present, and at the center of it all, there is one particular truth that very important ponies would very much like to keep a secret.

Autumn Breeze was sure that she would never experience any real excitement in her life. She thought a boring existence in the city of Manehattan was all the world had in store for her. But when her father is kidnapped by a secret society, Autumn is forced to run away from home. She soon finds herself embarking on an epic journey to discover Ancient Secrets surrounding the Great Schism and the legendary Princess Twilight Sparkle who hasn't been seen in centuries. With the help of her best friend Indigo, Autumn will have to uncover the story of the mysterious Princess clue by clue, place by place, until she has learned the truth that Celestia has tried so desperately to hide.
Destiny makes interesting choices, and it is often those you expect least who are chosen to do amazing things.
