There are many stories where Twilight tells off her friends after the Wedding. But that's not really Twilight's bag, she gets worried she's failed, or depressed, not angry. So here is a different bridal path, one where Twilight acts decisively to try and redeem herself in the eyes of her friends and sovereign, and ends up travelling to places she never imagined, facing dangers and foes she never dreamed of and making even stranger friends. Of course, there is still a 'reason you suck' speech delivered, but delivered by the last person anyone would expect...

Words and actions can sometimes hurt more than we know, sowing betrayal and hatred where friendship and innocence lies. A single thoughtless action can be a tipping point, one fallen domino setting off hundreds. Look back, and answer me.

My attempt at a more serious 'Luna meets Neil Armstrong' storyline. What would really happen, both on the moon and on Earth? Inspired by 'The Eagle has Landed' by CyanBlackStone.

Princess Luna has found herself on a very different moon after some strange force interfered with her banishment. She doesn't know what the metal objects that keep orbiting and sometimes landing there are, but she wants to find out. Meanwhile, Neil Armstrong believes that being the first man on the moon will be the crowning achievement of his life. Hoo boy, is he ever in for a surprise.

For those who are interested, the most excellent Zanec has provided this link to an interactive Apollo 11 site.

A damaged robot pony, unlike anything ever seen in pre-industrial Equestria, is found in the orchard. Before it collapses, it says only two words: "Twilight Sparkle..."

Twilight fixes the mechanical mare and gives her a new directive: "Make friends." Now a robot must learn what it takes to be a good friend and, while she's at it, what it means to live...

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:
