Feature box story of December 27, 2013. Thanks, everyone!

Many ponies have sworn by Celestia's beard over the ages, but where did this phrase originate from? Twilight Sparkle, her brain ever-thirsty for knowledge, asks this of her mentor, and learns a lesson she'll never forget.

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.

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:

Important notes about the status of this story below

Ever wonder what Equestria's past was like? How did Celestia and Luna come to rule? And what made their rule a time of peace? Well I may have had something to do with that.

Name's Zack. I appeared in Equestria over 3000 years before the show "My Little Pony: Friendship is Magic" takes place. For whatever reason, a few months after my arrival, I was transported to the modern day Ponyville. What happened? Are the Princesses mad at me for disappearing like I did? I only helped establish the greatest country this world has ever seen and then vanished.

That... sounded more innocent in my head. Uh oh...

A/N:
Just to let you know ahead of time, this is a ponified human, 1st person story. If you don't like it, don't bother.
The cover art was made by me, with the exception of the night sky bg (Wertyla).

Edit August 2nd 2016: I want to rewrite this story from the beginning. Read this for more info and tell me what you think.

Edit May 24th 2017: IMPORTANT! I am currently rewriting the entire story and with that, many details and aspects are set to change. As such, it will essentially be an entirely new story, meaning this version of Past, Present, and Future is technically Cancelled. There will be no more chapter updates until I finish the rewrite, meaning that this version will not have a proper ending. If it's requested enough, I may do some kind of Cliffnotes version of how the rest of the story was meant to play out, but for right now just know that if you start reading this version, you will not get an ending. I will post an announcement chapter on this story and Blog on my profile when the writing nears completion and I'm about to start uploading chapters. Thank you for all of your interest in my first public work of fiction. It really means a lot to me.

In the final days of her life, an exceptionally faithful student muses on the subject of her perfect and immortal mentor Applejack.

Edit: Now a collaborative effort with Loyal2Luna

Commander Shepard has been through a lot, but now that the Reaper War's over he can finally relax and take a little R&R, right? Soak up the sun, grab a few drinks, spend some quality time with Tali, introduce a new race to the galaxy... wait, what?

In the aftermath of the war, a new species has been discovered amidst the destruction and fire. A species that have access to powers never seen before, powers which could prove vital to the continuation of galactic survival.

The Citadel Council has elected to send Shepard, along with the rest of the crew of the Normandy, to introduce Equestria to the universe outside of their solar system.

Now Shepard must wade through obstructive bureaucrats, antagonistic journalists, and the odd, angry prince in order to bring Equestria into a new age of space and adventure.

So settle in, it's going to be one hell of a vacation!

Now has it's own TvTropes page

We all dream of going to fantasy worlds we like one day. Well, that happened to me once. However, not everything was all sunshine and rainbows. What if there's a higher reason? We all like to think there is, but perhaps this time there truly is one.

If you end up with a feeling of why is the main character like this, well, I have a reason for it so don't stop reading because of that.

Comes with a nifty sequel here, and a final volume in progress right here.
