Commander Shepard remembers firing the crucible. She remembers she had to make an important choice. She remembers good friends, a lover, and plenty of loyal crewmen.

She just can't remember what her choice was. What the threat she was striving so hard to end was. Or what the faces of the most important people in her life look like.

She also has no idea how she wound up in the monster filled forest she's come to call home for the past eight months. Or how she picked up a snarky A.I. making its home in her omni-tool.

Fluttershy is fine. Really, she is. Sure, she was a magically created fruit-sucking vampire hybrid a week ago, but now she’s fine. She’s seen a pair of fangs in the mirror now and then, but she’s fine. She drools at the thought of apples, but she’s fine. Nothing to worry her friends about.

It’s not like she has a problem or anything.

Everything. Is. Fine.

Becoming an immortal alicorn princess pony can be hard on a mare. On the one hand, Twilight now has near limitless power, but on the other, with great power comes great annoyance. Luckily that whole "near limitless power" thing kinda negates that. Still though, no one ever said banishing everypony to the moon would be easy.

Written for The Writeoff Association's inaugural writeoff, Lonely Happiness.

Twilight Sparkle is aware that the manipulation of matter at the sub-atomic level is a potential source of enormous amounts of free energy. She also knows that this is extremely dangerous, and that these spells are only for the highest level unicorns. She is therefore somewhat concerned to discover that Pinkie Pie has found another way to do this, with a curious contraption in the basement of Sugarcube Corner.

This story is a sequel to Dash of Humanity

I'm stuck in Equestria, which reminds me of the dark ages. Instead of internet and fast-food, I have Rainbow Dash. She's been asked to help me learn to fit in... I'd like a refund.

I suppose we got off to a good start, aside from being told that after all I'd done I'd never see Earth again. So long as I can look on the bright side of life, and not get arrested for running pranks on everypony with Dash, I might just survive long enough to find my purpose in Equestria. So help me, however, if I get any vegetable related cutie marks I will choke a Princess.

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:

In a world ravaged by the living dead, one man has outlasted those with far more strength, speed, and experience. His only advantages are his uncanny luck and peculiar inspiration. This inspiration has never led him astray and even promises a fresh start. All he has to do is build a strange device that follows no earthly science.

While Earth’s story might be over, this cog-jockey’s has just begun.
