Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Kuno, a young changeling, is left weak, bloodied, and bruised after the events of the Canterlot wedding. She is soon discovered by Warden, a Royal Guard. But for some reason, Warden shows her mercy. Instead of taking her into the custody of the Royal Guard, he becomes both her captor and her savior. But over time, Kuno will come to ask herself the hardest question she has ever pondered: Can a changeling feel love?

Pincer is a changeling, a proud soldier of Queen Chrysalis. After the failed invasion of Canterlot, he finds himself trapped and at the mercy of Princess Celestia's Royal Guard. Believing that Celestia sees his species as nothing but soulless monsters, he prepares himself for the worst. The weeks crawl by, marked by an endless series of questions he will not answer for fear of endangering his friends and family at The Hive. As his nerves wear down and his interrogators learn just how ruthless he thinks they are, they have nothing to report but his belief that they will kill and destroy his kind without mercy.

Celestia steps in to prove him wrong, and what Pincer learns leaves him questioning everything he has ever known — but also gives him hope for what he'd never thought possible.

Now with a TVTropes page.

Jessica finds herself flung into a world she has little concept of. Everything is strange and new to her, but worst of all she cannot communicate with the native inhabitants. A world of monsters and sapient ponies, griffons and other assorted beasts is no place for a human girl.

How will Jessica cope? Without an understanding of their language how will she make her way in the world, will she even be able to ever communicate with them? Why was she even brought into the world and is there even a way for her to get home?

(Also now apparently has a Tv Tropes page in the making. )

Big Mac has always kept to himself, rarely talking, and just enjoying the simple things in life. But when a mysterious new mare shows up in Ponyville, questions start to form in the back of Big Mac's mind. As a relationship blossoms between the two, the young mare's past starts to unravel. Will her secrets tear them apart, or bring them closer together?

In the Crystal Empire, a young filly appears from single feather from a pony and the lingering dark magic of King Sombra and she runs away on her own.

Now, the filly finds herself under the care of Fluttershy and Big Macintosh, who came to call her Petunia Snow, and lives in fear of these dark shadows in her head. What will become of the new filly? Will she flush out these dark vissions and except others into her life? Or will she become the new Sombra and spread her dark shadows over Equestria through the beautiful Crystal Empire?
