I'd heard about the TV show My Little Pony: Friendship is Magic from my college roommate who is way too into the show. Disturbingly so, actually, but good gravy I would never watch the darned thing! What am I, five? I've got better things to do with my time than watch a silly little girl's show. However, that didn't stop... something from transporting me into the world of the show, so here I am... in Equestria... trying to get home. This is gonna be interesting.

Special thanks to GuyFace, Jack Kellar, Storm Shaker, Spiffy McSquee, and Goober Trooper for helping me with this one!

Beware of Infinity War Spoliers:

When he snaps his fingers half of all life in the universe was wiped out. What happens when Equestria is the next planet effected by this

Note: This will be very emotional and won't have a happy ending (But if this story does really well, I may do a sequel.)

Warning: Some bad grammar

Luna discovers something hidden from Celestia for twenty years, now, with emotions running high, she enlists the help of the Mane 6... but what seemed to be a single mystery, soon reveals a darker and much more complicated plot that will soon decide the fate of Equestria.

Silver Spoon’s day doesn’t go like any other. Her friends on the household staff treat her more like their boss, rather than their friend; Her three best friends no longer like her for some reason, and the biggest and most arrogant school bully who has been tormenting her for years is acting suspiciously friendly towards her.

Silver Spoon’s day doesn’t go like any others. The house servants are more talkative and more friendly than ever, no longer acting as formal and professional as they should. Three blank-flanks keep inviting her to spend time with them for some reason, and her best friend Diamond Tiara… betrayed her in worst way possible.

Something is clearly wrong.

How will each Silver Spoon survive such a big change in their life, and how will everyone react to their change of attitude? Only time will tell.

This story is a sequel to Daughter of Discord

A series of one-shots detailing the adventures of five fillies on a quest to find what makes them special and earn their cutie marks.

Prism: the flightless pegasus overshadowed by her Wonderbolt parents and her talented older siblings, eager to prove herself to her family.

Gemstone: the spoiled yet slightly absent-minded unicorn hailing from Canterlot, seeking out friends who will accept her for who she is.

The Tri-Pies (Blueberry, Raspberry and Cherry): the energetic triplets, joined at the hip since birth (not literally), but cannot seem to handle themselves individually.

Stories (no real spoilers, just brief synopses):

Weekend at Uncle Discord's: Day Three (completely unrelated to the plot of Days One and Two): Gemstone and the Tri-Pies come visit Prism at Discord's castle for a play date.

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:
