Hi, my name is Ditzy Doo. Many of you know me as the author of the 'Wasteland Survival Guide'. For 200 years I wandered the Equestrian Wasteland, and through those experiences I gained the knowledge that I shared with everypony through the Guide. Now, it's time to tell my side of the story.

After Starlight Glimmer's misadventure beyond the Magic Mirror, Twilight Sparkle creates an artifact that will allow its wearer to travel between planes of existence without allowing excess magic to leak from one world to another and upsetting the delicate balance of worlds.

In doing so, however, she soon discovers more about herself and the spark that awakened the Element of Magic than she could have ever anticipated, and learns of a secret that Celestia had been keeping from her all her life.

Stranded in the world-spanning city of Ravnica, Twilight Sparkle must now seek to understand herself and the strange new plane of existence she's found herself in, and come to terms with her own role in Equestria and the Multiverse.

Sunset Shimmer almost succeeded in taking over Canterlot High, stopped the Sirens from taking over her new home, and managed to prevent the destruction of two worlds. She feels that she deserves a break and decides to return to Equestria during her summer break. Unfortunately, when she enters the portal she appears in a land that is different from the worlds she's already been to. Now she has to save this world before she can even focus on returning home.

Unfortunately, she's not the only Equestrian that's appeared in this new world, as one of Equestria's most dangerous villains is loose to do whatever he pleases. How will she cope with having to save this new world from Tirek?

They say that I must send my sister to the moon for one thousand years. They say that she is too far gone, and that it is for the best. But I cannot believe that. I refuse to believe it! Luna is my sister after all, and I can still save her!

But then a small part of me asks, What if I really can't save her by myself? What if... what if they're right?

Inspired greatly by the Luteces' cameo in Trade Ya! You do not need to have played BioShock Infinite to read and understand this story.

Also, many thanks to Alicorn Airport, Kirito-Persona and Protopony350 for being my pre-readers. Many, many thanks as well to Haycart for being my wonderful editor.

And many thanks to Will-Owl-the-Wisp for the amazing cover art. You can find the original here.

Now with a story reading by myself, Wisp, and MelancholyIguana.

Warning: Some spoilers to the end of BioShock Infinite in the comments.

Mr. Horse's pet courier has been murdered and his property stolen. And while the price on the killers' heads is good enough to get any bounty hunter's attention, it's the bonus for returning a silly little poker chip that draws Dead-Shot in.

A pony could retire on that kind of jackpot...

It's just another day of weather bucking for Stormy Skies. Nothing special, as usual. Then, like a bolt out of the blue, everything changes and nothing is the same again. Now she finds herself accused for crimes she didn't commit and threatened by unknown assailants. But can she trust the mysterious mare, Misty Morning, or is she a part of the plot as well?

(Edited by Icy Shake)

After Twilight Sparkle became an Alicorn Princess everything was going to be just fine; and for a time, everything was: Equestria began expanding at an alarming rate, with amazing breakthroughs in technology and lower crime rates everywhere. However, things never stay perfect forever. Little by little, Equestria's rule has become more and more dictatorial, with violence in the streets and ponies mysteriously disappearing for speaking out against Princess Celestia; and Twilight Sparkle is at the centre of it. A stallion named Shining Armor is able to see the truth beneath the layers of deception. He heads to the city of Canterlot to rescue his sister and get her away from all of it. He knows that his sister is in trouble and he will be saving her from a terrible fate, but throughout his adventure, he will uncover a horrifying series of events and a plot that threatens all of Equestria.

The protector, otherwise known as the Big Daddy, is often regarded as the ultimate killing machine of the underwater utopia known as Rapture. They are nearly indestructible, can endure the crushing pressures of the bottom of the ocean, and possess a variety of killing tools.

Through a completely unexpected sequence of events, a Big Daddy is sent to Equestria through a tear. Knowing the kind of havoc a Big Daddy can cause, Booker DeWitt and Elizabeth pursue the behemoth to get it back.

But they're too late.

Takes place in the BioShock: Infinite- Burial at Sea universe, in an alternate timeline. The events of the DLC Burial at Sea: Episode 1 do not happen. Booker and Elizabeth are not trying to find Sally. NONE of your favorite ponies are getting killed, I promise.

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!

Thomas Miller proudly wore the armor of the feared Firemen of Columbia. Battle hardened and devoutly loyal; nothing could prevent one of Comstock's most elite soldiers from completing his mission. Even if that mission was to apprehend the Prophet's daughter, Elizabeth. He had a goal that no force on heaven or earth could stop him from achieving.....except perhaps Elizabeth herself.....

What happens when a pyromaniac finds himself dropped in the middle of Equestria?
