In 2185, during his campaign against the Collectors, Commander Shepard discovered a previously unknown species whose origins predated any other race in the modern galaxy. Following a daring rescue from their ancient sanctuary, the Equestrian Herd was brought back into the galaxy where, for the first time in eons, they must walk their own path.

Knowing full well the terrible threat that lingers on the edge of the galaxy, the leader of this newly freed race fights to secure her people’s future while attempting to prepare for the storm on the horizon.

This is her story.

The long awaited Sequel to Mass Effect 2: The Equestrian Equation This is a reader directed story. Your choices will shape events.
If you favorite, also like! It's one little button click that makes all the difference.

Also, this series has its own TVTropes page now! (Special thanks to user CrowMagnon for setting it up).

A minor injury leads Apple Bloom to learn that she and the other Crusaders aren't like normal ponies. Not having their marks has always been their common bond, but as the trio uncover their unique nature, it becomes clear that their lives are intertwined on a much deeper level. As they learn the secrets of their shared past, it leads to revelations about their friendship, families, and their long sought after talents. What they discover and accomplish along the way is beyond what anypony would have thought possible.

There is now a sequel! Three Wishes: The Hole In The Sun

And a (more or less) standalone Christmas Special set between this and the sequel. Cinder Claws: The Caribou Legend Of Kol-Klor

Big thanks to totallynotabrony, Dusk Watch, AugieDog, and Piquo Pie for prereading and editing help!

After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

If there are three things Principal Celestia can't stand, it's paperwork, princesses and her past. Unfortunately, the first makes up her job... and she desperately needs the second to help her resolve the last.

Shawn Spencer, psychic detective, is a thick-tufted boy genius who ice skates through life on polished blades of snarky eloquence. He has tested himself against some of the greatest criminal minds of his time and emerged victorious... though often through unbelievable luck and not a small amount of bumbling.

Now, he faces a challenge unlike any before. One that will test his mind, his sanity, and his adaptability as he is thrust into the midst of an unfamiliar world and the ponies who populate it.

The Mane 6 face their own challenge, as an old enemy, tempered in the crimes of a much harsher world than theirs, returns to Equestria. It is a challenge they are ill-prepared for and one that only their strange, new, alien friend can help them overcome.

A close encounter with a category three Kaiju leaves Midsummer Night, a Mark-II Jaeger, in the inky depths of an unknown ocean. With no communications or navigation available, the pilots, Shane and Michael O'Connell, are well and truly out of their element.

Good thing they accidentally brought something with them to liven up the party,

Now with a Tvtropes page!

When strange ponies from another world suddenly pony-nap all her friends, Pinkie Pie must find a way to defeat their master all on her own. Blamed for the crime herself, she has no help from Celestia and just about every pony in Ponyville is convinced that she's finally cracked. Who can she possibly find to fill in for the other Elements of Harmony, and help her defeat the ancient evil behind it all?

This story occurs after Discord is defeated but prior to the rest of season 2. Story is featured on Equestria Daily and is now officially a 'six star' rated story! Full size image can also be found there.

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:
