"All my life, I've wanted to fly
But I don't have the wings, and I wonder why
I can't break away..."
Most pegasi figure out flying easily enough. Heck, most of them figure out how to do it before they even get their cutie marks.

But not me. I couldn’t do it, no matter how hard I tried. I couldn’t even hover. Not for more than a few seconds, anyway. And not even Rainbow Dash, the greatest flier in Equestria, could seem to help me. We tried everything, and I failed every time. Day after day, I tried – and day after day, I failed, until finally I was ready to just give up. I’d never be able to do it. Nopony would ever be able to help me to fly...

...until one day, somepony did.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

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?

Troy is a Gryphon who moved to Equestria to pursue a new life; however, his seclusion has left him feeling unsatisfied with how his life was going. All of that changes when he becomes involved in a storm prepping job outside of Ponyville for Princess Twilight Sparkle. Before the storm, Troy finds Canvas, a badly injured Earth pony, lying on the ground near death. As time goes on and wounds start to heal, how will the Gryphon's life change as he helps the stallion struggling to regain control of his life?

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:
