This story is a sequel to The Fallen Age

Long ago, before the rise of Equestria, long before the Three Tribes Era even, Equus grew and prospered under the rule of the seemingly immortal Empress Cosmos. For two thousand years, she and her five Exarchs guided the many races of the world into a better future.

And then, she vanished, and her name and all she had done was forgotten.

Ten thousand years have passed since that night. Her Exarchs have not been seen in millennia, and the few who do know of that time think they died long ago.

The civilization she helped create is now forgotten by most, destroyed in a war born of xenophobia. One that heralded the rise of the Three Tribes Era.

But now signs have begun to appear. A long-forgotten prophecy is about to be fulfilled. The once and future ruler of Equus is about to be reborn. But what does this have to do with Twilight Sparkle and the five new ponies who have just arrived in Ponyville?

Twilight is on the cusp of leading Equestria for a year. It's been an easy year with no major difficulties. No wars. No natural disasters. No villains.

At least until a villain from the far, far future appears in Twilight's throne room. She's escaping defeat at Twilight's hooves, with one thought in mind: she won't be stopped if Twilight doesn't exist in the future. And here's Twilight's past self, right in front of her. Easy.

Unfortunately, she's not the only villain with this idea.

Twilight has an unexpected Hearths Warming Eve guest. Normally not a problem but she misunderstood the situation. Thankfully Luna is here to help. Well, maybe not thankfully, but she's here to help either way.

There's some rather silly violence, so it's not exactly for "everyone" but it's very, very tame teen.

Twilight Sparkle is tired of this nonsense.

Every day, a slew of articles all focused on the minute details of her life invade her beloved newspapers. "Twilight Sparkle Eats Peaches." "Twilight Sparkle Hates Tea." "Twilight Sparkle Uses a Microwave." "Twilight Sparkle Makes Toast." All of it clogging up her precious sources of information from cities across Equestria.

But no more. The time has come to put an end to it, once and for all.

Written with thanks to Marceline from the #FimFiction IRC and for no good reason other than it sounded funny in my head.

Twilight looked over to her dear mentor, Princess Celestia, and found she had once again fallen asleep mid-lesson. Her intense debate on awakening the princess was cut short when the decision was taken out of her hooves.

“Huh? Oh. Twilight, I am so sorry for falling asleep again. I think we need to reschedule this for tomorrow morning.”

Twilight nodded. After all, Princess Celestia was obviously overworked. If only there was something she could do to help.

She really should've expected these results.

Now featuring a reading by StraightToThePoint Studio! Thank you to them.

Angel Midnight wrote an unofficial sequel called The Royal Sisters Take A DNA Test. Go read it.

And if you wish to write your own sequel you may go ahead. All I ask is that you provide me a link when you post it.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

TV Tropes

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

This is a fic based on the Time Loop Files, the format of which was first codified by Innortal on fanfiction.net.
Here's a brief guide.
The basic idea is, one character (the Anchor, usually the main character of a fictional setting) is looping back to the very first moments of their parent series every time either they die or some kind of time limit expires. They of course end up monumentally stir crazy given enough time.
Eventually others start to loop as well.
The reset is not always perfect. Sometimes a loop's history will be different to the "prime" loop, or canonical plot.
"Crossover" or "Fusion" loops also occur, randomly. These can involve the home loopers having a guest, or the anchor for one universe spending time in another, or replacements of one character by another.
Vacation Loops are where the Anchor (or others) decide/s "buck it" and lets off steam by doing whatever comes to mind. There's little or no attempt to maintain the original timeline.

In addition, and particularly more recently, it should be known that this story has a collaborative element to it - people may submit loop ideas or loops, ideally at the Spacebattles thread (a link to the current version of which is on the Trope page), and they may become included.

There's two page image options, thanks to Filraen - the current page image has been edited by the original creator from this work of theirs.. The other one is here:
