Once upon a time, in the magical land of Equestria...

One week ago, Twilight Sparkle was crowned the fourth Princess of Equestria. Tonight, Ponyville hosts the 1003rd Summer Sun Celebration, and Princess Celestia and Princess Luna want a vacation. With two fine young princesses like Cadance and Twilight to take over for them, nothing could possibly go wrong.

The princesses gave their magic to Twilight to prevent Tirek from stealing it. As a result, they end up stuck in Tartarus.

Marvelous place, Tartarus. Really brings ponies together. The fact that things manage to go downhill here says a lot about the wonders of family and alicornhood.

This story is a sequel to The Secret of Manehattan Mall

When Pinkie Pie receives an acceptance letter from one of the most prestigious culinary schools in the world, she is given a chance to achieve her life-long dream of becoming a world-renowned pastry chef. Although this trip means being away from Ponyville and her friends for an entire year, the new friends she meets and the fresh opportunities for crazy shenanigans more than make up for it.

Pinkie might be ready to take on this new environment, but the real question is: is it ready for Pinkie Pie?

The Wonderbolts are putting on a show in Manehattan and Rainbow Dash just has to be there. But arriving a day early means that she and her friends, Pinkie Pie and Fluttershy, have twenty-four hours to whittle away. And what better place to kill time than the mall? In the largest shopping center in Equestria they'll find food, fun, maybe even a new friend. A whole day of hi-jinx and shenanigans.

But unbeknownst to the three friends, something is being hidden within the walls of Manehattan Mall. A dark secret hidden from the masses. And they're about to get involved, whether they like it not.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

Helping a lost filly find her way home should have been a walk in the park for Princess Twilight Sparkle, but this time things turned out to be a bit stranger than she was expecting.

This story is a sequel to Getting Stuck

NOT in the "Shadow Wars" continuity, though it does use that continuity as backstory. Specifically, it would if in main continuity be set in Season 4 with all Shadow Wars.assumptions including most specifically Luna's and Twilight's past lives and Pinkie Pie's previous identity in the G3 universe (on which I was inspired by Alex Warlorn) as part of the backstory.

When a human who fell to Equestria through a dimensional portal rapes a citizen of Ponyville, Princess Twilight Sparkle is uncertain of how to handle the case, so she writes to Princess Celestia for advice. The following exchange of letters details that consultation.

Warning: this story is a very-unauthorized sequel to a rather nasty second-person story, NOT written by myself, which seems to be based on the premise that raping those caught at a disadvantage is unobjectionable. I do not endorse any of the opinions expressed in the prior work.

Note Well: The "romance" in the story doesn't involve the Human. Well, not the romance that I expect most readers to find warm and fuzzy, anyway.

Nightmare Moon spends a thousand years banished to the Moon, fighting herself and the Shadows both within and without. She watches civilization rise and spread, a quarter-million miles away.

Can she reclaim her power? Can she overcome the six champions her sister has sent to defeat her?

Why do three of the champions look terribly familiar to the renegade Moon Princess? Why does the sight of one, in particular, break her heart?

And why, as the battle continues, does she increasingly hope that she does not win?

This is an expanded version of the two-part Series Opener. From Nightmare Moon's point of view.

Now with its own TVTropes page!

If you want to find out what the Great and Powerful Trixie was doing in Manehattan, and what happened in some other parts of Equestria during the Longest Night, read An Extended Performance. The direct sequel, however, is All the Way Back.

To Twilight Sparkle and Princess Celestia, it is a simple surprise visit to Canterlot. To the ponies of the Equestrian Civil Service, it is twenty-four hours of chaos, politics, weaponized dessert, politics, underhooved manipulation of media, politics, and things batrachian and tentacular. Who said bureaucracy isn't exciting?

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.
