Bioshock meets MLP in this psychological thriller, where Celestia's new faithful student, Siren Song, must discover the truth behind the city beneath the waves.

Beautiful, gifted, and faithful student of the Princess of the Sun, Siren Song has very nearly everything a pony could want. Sometimes though, in the twilight hours, Siren can see the sadness in her mentor's eyes. Once, ponies whisper, the Princess had another student named Twilight Sparkle, but she left Equestria, never to return. The pony who has a perfect life just needs one more thing—to convince Twilight Sparkle to come home so the Princess will smile again. But when Siren arrives in pursuit of Twilight, she soon finds herself trapped in a city of horrors, with only its monstrous denizens for help.

Now with a TV Tropes page!

I don't see what all the fuss about death is. Our princesses have been dodging it for over a thousand years. Who's to say Sweetie and I can't experiment a little? No, don't be ridiculous, zombies don't exist. Not yet, anyway.

[As seen on Equestria Daily.]

Skittles are Equestria's latest trend, but when Rainbow tells Twilight that she doesn't like them, the studious unicorn comes up with a rather bizarre theory: maybe Rainbow tastes like Skittles herself, and is therefore immune to the taste. But are they ready to find out if her theory is correct?

Plowpony's Day- a day of peaceful rest and relaxation. Or it was, until Twilight Sparkle badly mangled a teleportation spell. It has left her with a bad case of Horn Rot, a disease that if untreated could prove fatal. What's more, the malady is advancing faster than the slow-brewing potion that cures it!

There is one swifter cure: the Beneviolet, a star-shaped flower that grows in the distant Archback Mountains, far beyond the western borders of Equestria. Applejack, Rainbow Dash, and Rarity choose to undertake the long journey for the sake of their friend. Their path will wind through floes of ice, across gold-tinted plains, into distant forests glimmering with magic. They will learn much about the world beyond their homeland- and much about themselves, as well.

Yes, it's "Dangerous Business," here on FIMFiction. A huge debt is owed to all those who have supported me over the years. I've edited the story some to remove extraneous bolding and italics, but other than that, it remains unchanged. I hope new readers enjoy it as much as old ones did.

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?

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."
