Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Twilight's relentless study of Pinkie's strange abilities leads to a horrifying revelation.

This site really needs an existential horror tag.

Twilight Sparkle had been looking forward to a quiet, relaxing day with a friend, and at first it seemed that Fluttershy could provide just that. But when Twilight makes a rather unsettling discovery about the pegasus – and her unusually sanguine appetite – the knowledge proves to be anything but relaxing...

Inspired by the heroics of the mysterious mare known as the Stable Dweller, Silver Storm, a guard of the town of Marefort, decides to go on a daring mission to rescue her captured brother. Of course things rarely go as planned and her attempts at heroism drags her into a tangled web of plots and conspiracies as warring factions vie for control over the last great city: Dise.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

Everypony who knows and puts up with Pinkie Pie and her antics is used to her spontaneous behavior, and her Pinkie Sense. Twilight herself had come to assume that was simply who the pink pony was. But one day, she discovers the true source of Pinkie's abilities. And unfortunately for her, a secret like this can only be revealed in one way... death.

This story is a collaboration between myself and Shadowflame. The author of each chapter will be made clear in the author's notes.

Dragons. Big. Selfish. Treasure mongers. No other creature in Equestria is as selfish as they. The spend their entire centuries long lives building and hoarding huge stockpiles of treasures, which they guard fiercely and frighteningly. Many are the treasure hunters who've attempted to cash in on the goldmine that is a dragons hoard. They almost always regret it.

One dragon is actually really strange about it, however. Oh, he has a hoard, which he guards just as fiercely as any other. But! But, he actually has the capacity to trust certain ponies and other creatures enough to let them gaze upon his most precious of treasures. This isn't the most surprising thing, however, despite its seeming impossibility. No. The most surprising thing is just what treasures his hoard contains...

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

Nopony ever said the friendship between Fluttershy and Discord would be an easy one. The difference in their life expectancies doesn’t help, but that’s a problem Discord can fix with a snap of the talons—that is, until Fluttershy finds out. Discord isn’t one to give up easily, though. He’ll do anything to keep his one and only friend. Anything.
