Rainbow Dash flies east.

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.

Twilight wakes in the middle of the night, haunted by a terrifying dream—one that's not so hard to see coming true. One that whispers of a grand destiny awaiting her as a reward for all her hard work, discipline, and noble sacrifice.

But what if she doesn't want a grand destiny?

Ponyville is shaken to its core when a body is discovered in the Everfree Forest. As the townsponies grieve, the mysterious Special Agent Bentgrass from Their Majesties' Royal Investigative Service arrives at the Books and Branches library and drags Twilight into a world she's only read about: lies, corruption, suspicion, and murder.

Faced with an indifferent police force, and Agent Bentgrass's infuriating methods, Twilight must put the pieces together and catch the killer. But as blood continues to spill and questions pile up, one thing is terrifyingly clear: in the dark of the Everfree, much more is at play than mere murder.

Lyra knows the truth. Lyra knows that a shadowy conspiracy dating back to the very dawn of Equestria is responsible for manipulating every major event for the past two thousand years. And Lyra does not care how many museums she has to destroy or how many transdimensional rifts she has to open in her quest to inform the public.

The Mane-Event, a popular stage show in Manehattan, has acquired a rare creature they intend to use as part of a new act. Their typical animal handlers prove inadequate for the new job so they invite Equestria's best to be the caretaker-- Fluttershy. Moving to a new city requires the inconvenience of finding a new place to stay, however. What fortune that Trixie, one of the primary acts of the Mane-Event, just so happens to have free space at her apartment.

And then the Element of Kindness lived with the Element of Egotism.

Some accidents are small, and some endow you with the power of a godly ruler. On the opposite end of things, you lose your wings along with your ability to move celestial bodies, and you can't tell anypony. Why, because what would they think if the princess became a librarian? It's going to be "fine". Celestia just needs to switch back with Twilight before either of their true identities are revealed. All Twilight has to do is hold down the castle, fight off scheming villains, run the country, and worst of all... deal with all the noble ponies.

Rated teen for shenanigans and some more serious parts. Takes place at the end of lesson zero. Please tear this apart with comments. I like criticism. Comment if you have issues, don't leave me with a mystery thumbs down.

The Lone Wanderer has been known as the man who shouldered the nightmares of every man, woman and child in the wasteland, so that they may live. But when the Wanderer was once again abducted by aliens, he found himself falling, quite literally, into a whole new wonderous world, untouched by the horrors of nuclear devastation.

He has been facing other people's nightmares constantly for almost a decade, it was high time he was allowed to wake up.

Meanwhile, the ponies of Equestria are baffled by a strange object that fell from the sky.

Distance can drive us apart. It can also bring us closer together.

After all is said and done, and the ponies have gone their separate ways, the only way they have to keep in touch is through letters.
