Everyone knows of Twilight Sparkle, personal student to the princess of the sun, and element of magic. She has friends, family, and above all, hope.
However, Twilight Sparkle doesn't exist. In fact, Equestria doesn't exist either. All it is and will ever be is a figment of my imagination. Simply a way to live out the rest of my days with a slight measure of happiness. I am not her, but I would give my horn to be her for but a single day. To have everything, and yet not realise how lucky you are to have such things, to live.
What I am doing right now is not living, this is waiting for death.

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:

We trained her.
We taught her.
We raised her to godhood.
She brought us down to earth.

Sequel can be found here: Memoirs in Ink and Blood

After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

The world spins, years pass, and everything comes to an end. Except Celestia. She sits on the shore of the last ocean, watching and waiting for her own chance at death. Because everything comes to an end if you wait long enough, and Celestia is patient indeed.

Discord was defeated. Villains always are. It’s really quite cliché.

Before he lost, he asked himself a question: what if your virtues went out of control, rather than your flaws? Perhaps if the heroes and villains weren't so clear-cut, the conclusion wouldn't be so inevitable. If nothing else, there would be some fun chaos along the way!

Can the main six find a way to undo Discord's magic, in spite of themselves and each other?

Disclaimer; I have been working on this for a while, and the writing at the beginning is not as good as the writing later. Hopefully it is not too great of an impediment to the story.

Editing by Meta Four, ocalhoun, Kuroi Tsubasa Tenshi, Sessalisk, Sereg, and JapaneseTeeth, all of whom are amazing. Go shower them with admiration!

They thought she was wrong, they thought she was being over protective of her brother.

They were wrong.

The wedding was saved but Twilight Sparkle went missing ever since her friends, bother and mentor abandoned her in that room. 3 years has passed but still no sign of Twilight. Suddently some kind of super advanced robots attack ponyville claming that they work for an evil organization called "Treble" who's only objecttive is to destroy Equestria.

With the new element of magic, Trixie Lulamoon, our heroes will defend their home no matter what. But Princess Cadence is convinced that Treble is connected to Twilight's dissapearence and she will look for answers to her werabouts.

( Contains elements form the Megaman Battle Network series )

During a trip to Las Haygas, Twilight meets a unique stranger and discovers a long-forgotten form of magic that may prove to be more trouble than it's worth.

“My daughter Celestia, look at me. I love you, and I wish the best for you in the eons of labor you have yet to endure. So heed my words. When we planted light upon the fields of Creation, Celestia, it was a divine thing. But there will come a time when our brilliance won't be enough. It will take a great, unknowable darkness to test the luminescence that we have bequeathed life. That is an abyss that we can never, ever follow our children down, no matter how much we love them.”

A Silver Medalist of the Ponychan /Fic/ Write-Off: "Cutting Ties"

I can't remember how long I've been alive. I can't remember my birthday. I don't even know my own name. I'd like to think I had a family... but I'm not sure. All these things are meant to be important to me, things I was never supposed to forget, and yet, I have. I have taken shelter in an old castle, in a forgotten city. I do not know why I'm writing this. I suppose just to keep myself sane, but perhaps keeping a record of my activities will help me piece together what happened to the world.

A/N: This is Celestia's immortality, taken to its logical (in my mind) conclusion.
