Princess Celestia asked Twilight to do a census of her new home. Through this process she discovers certain anomalies that she finds strange as a unicorn. There seems to be something missing when it comes to the pegasi, and after much prodding, prying, some spying and begging, she finally gets them to open up. What she discovers is not only shocking (to her, at least), but revealing on pegasi subculture.

Will what she learns change the way she looks at her friends? Will her friendship with them be ruined?

Nah.

(Set a month after the events of the season 4 finale)

Chrysalis has returned to Canterlot, but this time under a flag of truce, instead of a banner of war. She has come because her race is dying, and much to everponies surprise, the last hope for her race is in Equestria.

However, nopony is prepared for the news of who is carrying this last hope, nor the ramifications of what this last hope is likely to bring.

Rating: Rated teen for some sexual scenes and violence in later chapters.

Warning Number 1: Later chapters may contain scenes of graphic violence, viewer discretion is advised.
Warning Number 2: Despite the similar title, this is not a ponyfied version of the movie Enemy Mine.
Warning Number 3: I know Twilight is a unicorn in the cover, but she will be an alicorn in the story, just so no-one is confused.
Warning Number 4: Twilight's brother Shining Armor will me getting a major change to his character portrayal throughout the course of this fic, a change that will involve some dark undertones, which is one of the reasons for the dark tag.
Final Warning: This fic will delve deep into a fannon portrayal of changeling hive structure, hierarchy, and culture, so those who already have head cannon's behind those and are unwilling to accept or tolerate new ones should probably steer clear of this fic.

When Twilight plays with magic beyond her control, she finds herself and Rainbow stuck in a strange, horrible world. When they find out what happened, will they be able to get home? Will they even want to?

King Sombra came from an old age, a time where darkness and evil were prevalent across the land. The Princesse's power and influence were weaker in those days, for the land of Equestria was divided amongst many kingdoms of lesser Princesses and Princes. But out of all their ruling neighbors, The Four Shepherds held the most power of all, even threatening Celestia and Luna's kingdom. However, all of that changed when they vanished for a thousand years, ushering in a new era of peace and prosperity. Until that is, when the Crystal Kingdom reappeared, along with one of the Shepherds. King Sombra, however, was thankfully vanquished swiftly, but the following peace of his defeat would not last as long as anypony might think. A new force sets its eyes on the recently coronated Princess Twilight Sparkle, one that seeks to restore a lost heritage and remind the land of who is the true owner of the night. For when one evil is smitten, another appears in its place. And King Sombra was only the first in line.

Set before Season 4

Special thanks to my editor Ladrian for his diligent and superb work. I wish I had him when I first started this story because maybe then the early chapters would have been much better.

Special thanks to Stanku for revisions and prereading this story. It would be at a much worse state had it not been for his detailed opinions to each and every chapter, and letting me know where I can improve.

10/2/2014 : Woah... it's on the featured list... *cue squealing and fist pumping* THANK YOU ALL SO MUCH!

A Reading of the Prologue by TheFirstPersonGamers

Diplomacy has failed. Six years have passed Equestria's crowning of the princess of friendship, ushering in a supposed unprecedented age of peace and harmony. The concept of warfare is, to most ponies, nothing more than an unfathomable legend. They have let their guard down.

An unknown enemy has seized the opportunity to attack Equestria with terrifying new weapons of war, bent on taking the fertile land and restoring an ancient order. The valiant efforts of the Royal Guard have given Princess Twilight and her arcane scientists time to research and develop a response to their attackers, and the time has come for that response to be implemented. Utilizing weapons and tactics borrowed from another world, five squads under the command of Princess Luna will infiltrate the forests of the Equestrian Northwest to destroy a revolutionary magical matrix that Twilight refers to as the "radio" - a tool that allows enemy ponies to communicate across vast distances instantly.

Nightmare Two is comprised of three foalhood friends who, rather than be separated from each other in the draft, volunteer to become one of the five Nightmare squads. With their bodies forever altered to suit the needs of their mission, the three young mares join legions of ponies armed with powerful weapons to partake in a horrifying new breed of warfare - Equestria's first in over one thousand years.

Heads up, folks. If you wouldn't mind leaving a comment alongside the thumbs-down, I'd appreciate it. This is my first foray into fan fiction and although it's a hobby I nonetheless wish to get better. :)

Got some FAQ's for you guys as well!

- Alternate universe in which the events of "Crusaders of the Lost Mark" did not occur. (As much as I loved it! :D)

- Numerical age tends to vary with headcanon, but the CMC here were just getting started with their adult lives when the draft went into effect.

- The war is pony v. pony, utilizing firearms and the Equestrian equivalent of a tank. The underlying headcanon is that ponies used firearms similar to muskets and tracked armored vehicles akin to our tanks in times of old, and what the enemy currently employs is essentially the natural progression of these technologies.

- There are no real-world weapons or equipment i.e. "Panzer IV," or "M16 assault rifle." Particularly acute details such as the caliber of weapons are also absent.

- Technology is based on that of WWI with some WWII elements. Firearms are primarily bolt-action.

- The "radio" spell matrix functions as what we know to be a radio, but is not identical.

- All four of a Night Mare's legs are permanently replaced by the augments.

- Night Mares are female. Stallions proved unable to properly animate the limbs.

Twilight Sparkle is lost and broken, living a new life in a new town, she has forgotten who she truly is. Something happened to Twilight in Equestria that caused her sudden departure, and has half of Equestria scouring the planet for her.
"What did I do?" Is... not a question Twilight had thought of. She'd been happy, and content living her new life in Frostglade. However, she'd always felt like there were pieces to herself missing. Like, she'd lost something important.

When Sunset Shimmer and Trixie Lulamoon finally track her down after months of searching (and barely tolerating the other's presence), the reunion is not a happy one. Their presence has upset Twilight's new life by revealing the first step in unraveling the web of secrets bottled up in Twilight's psyche.

The three mares journey to a place of ancient magic, where they must piece together Twilight's shattered memories, solve the mystery, and then finally go home to where they truly belong. Of course, their journey will not be easy; dark shadows follow Twilight's every move, trying to stop her party from seeing the truth. If that weren't bad enough, it's not just Twilight Sparkle who is being tested by the challenges of the Nexus.

Twilight gets killed protecting Princess Celestia and wakes up to the words Game Over floating in front of her.

Some Canterlot entertainers aren't just musicians... and some ponies fall in love with them anyways.

When one of Equestria's most popular cellists appears at Twilight's birthday party, it's just another gig for Octavia, but a shock for Twilight and the rest of the party-goers. She arrives, wishes Twilight a happy birthday, wows them with her beautiful music, wows them with her musical beauty, and doesn't leave until after everypony else has left. So when a few ponies suggest that this 'entertainer' might be more than just a musician... some eyebrows are raised, but nothing more. Twilight is beyond reproach, after all, and Octavia can earn her living however she wants. When she sticks around Ponyville, however, it becomes a slightly different story - Twilight is romantically-naive, after all, and Octavia is... most certainly not.

The romance of Twilight Sparkle, Celestia's protege, and Octavia van Clef, Canterlot's most famous entertainer.

Rated 'Teen'. Per FimFiction's rating guidelines, this story contains some 'more adult themes', but has no 'graphically adult content'. Rated primarily for sexually suggestive material, but also (in later chapters) alcohol use and adult language.

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:
