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

Queen Chrysalis planned for months to finally take Canterlot for herself. Months of reconnaissance, bribery, and maneuvering to finally lower the defenses of the Equestrian capital at just the right moment. But while her stated goal was always to have enough love to feed the desperate Swarm, the reality of the invasion was something else.

The queen spawned thousands of drones, filling the sky with untrained warriors in order to marshal the greatest forces when the day of battle arrived. But then that day came, and they won. Now what? Most of those drones didn't even matter enough to earn a name, and so they will probably die unremembered. But at least one is determined to make something of herself in her queen's new world. She's determined to understand these strange creatures called ponies, and to survive the invasion no matter what.

Begins during a reimagined Canterlot Wedding. Updates every Wednesday.

Twilight Sparkle accomplished something incredible, something not even the great Starswirl could manage. But ascension into the ranks of Equestria's princesses is not without its difficulties. Before she can take her place as princess of Friendship, Twilight must travel to the underworld and make a ceremonial offering to Death in exchange for her immortality. Twilight is more than a little surprised to discover the identity of the pony under the hood.

After years living in Ponyville and getting to know her friends, Twilight always assumed they were exactly what they seemed: a group of friendly and ambitious ponies. But as it turns out, the sort of pony who saves Equestria and decodes the ancient mysteries of Starswirl is likely to attract ponies a tad more interesting.

Updates on the 3rd or 4th Friday of every month, then daily until that section is complete.

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.

Starlight Glimmer had the perfect plan: using Star Swirl's time travel spell, erase the Sonic Rainboom and everything it did. After failing to stop her, Twilight was returned abruptly to an Equestria that bears little resemblance to her home, where the other Elements of Harmony don't even know her name.

It should've been simple then: use Star Swirl's magic to return to the past and stop Starlight from changing things. Unfortunately for Twilight, all the magic in the Cutie Map is gone. She'll have to find another way to put Equestria right, and fast. After all, the Elements didn't stop Nightmare Moon...

Twilight Sparkle didn’t care about overseeing the Summer Sun Celebration in some podunk little town. She just wanted a chance to study the history of the Lunar Rebellions and maybe, just maybe, convince Celestia that her sister’s return was a real possibility. Now it’s a lot more than just a possibility, and one Canterlot egghead isn’t going to be able to take on Nightmare Moon and her army alone.

(Season 1, Episodes 1 and 2 of My Little Pony: Friendship is Magic rewritten and expanded as a mature fantasy adventure)

Inspired by KnightMysterio's take on the Nightmare-Timeline in the story Context

The Princess of the Sun has fallen, the Queen of the Night now takes her place.

To the surprise of many, Nightmare Moon isn't evil. Or insane for that matter. She is attempting to be a queen that can properly rule a nation she has not seen in a thousand years. Some will try to aide her, others will attempt to thwart her, but the Wrath of the Night is something not to take lightly.

However, Celestia may have made a mistake in letting Luna fade from history and the only mention of Nightmare Moon become a demonized fable- no one would take that very well in her place.

Features: Twilight reluctantly helping a Sane and Noble NMM, curious and confused guards, and ponies being reminded of their lost history.

In the wake of Twilight’s escape from her kingdom, Nightmare Moon sentences Rarity, her palace steward, to a terrible fate: bound in gold and priceless gems, she’s to be thrown into an ancient dragon prison to be messily devoured.

Except the prison isn’t what it seems, nor is its sole occupant. Rarity just might find her life instead of losing it, and alter the course of Equestrian history in process.

This story is a sequel to Learning ABCs - Adorable, Bothersome, Chaotic

Ever since Discord did NOT tell Twilight just who planted the seeds that nearly threw entire Equestria in disarray, Twilight has been giving this secretive relationship-y thingy some serious thought. But it is hard to hold Discord down from doing what he wants and getting what he wishes. It is going to be hard to juggle his chaotic persona with the harmonic balance of the kingdom she was chosen to rule.

It is also probably going to be quite funny.

Eric, easygoing local human, is winding down for the night when he receives an unexpected visitor.

He is a good host to them.
