Rainbow Dash usually had her head in the clouds, but she always thought she knew up from down. When an incredible revelation sends her life into a tailspin, she finds herself at the mercy of emotions she never thought she had, faced with hard questions and impossible choices.

Life is full of changes, but none of them are quite as disturbing as having a horn pop out of your skull…

Original Lauren Faust canon; non-alicorn Twilight, non-alicorn Cadance, no ascension. Diverges from the cartoon after season 3, with nods to later continuity wherever possible. Contains mature themes.

When Ruby boards the first trans-oceanic flight in Equestrian history, the last place she expects to end up is stranded in the middle of Eternity's Crossing in the wake of a horrific zeppelin crash. After a mysterious tower leads her and a fellow survivor to discover a twisted and fragmented city twenty thousand feet below the surface of the ocean, though, a bit of fire and smoke is the last thing she needs to worry about. Between the horrendously disfigured residents and the paranoia of the madmare who once built and controlled it, daily survival in this corrupted utopia is anything but a guarantee. But with the help of some new friends and a few genetic enhancements, Ruby isn't going down without a fight, and in the process might just discover that the deadliest weapon in Harmony is herself.

An adaptation of BioShock for the world of MLP. Written to be comprehensible to anyone, regardless of whether they've played the original game.

When English teacher Connie Hayden is told by a mysterious new friend that there is a way to travel from the human world to Equestria, she doesn't believe her. But what if the legend of Pinkamena is true?

Twilight's slight miscalculation with the Elements of Harmony land her and Rarity in a telepathic funk. But when Princess Celestia goes missing, it looks like having a window into each other's minds is going to be the least of their problems. The Mane Six will find themselves everywhere from Equestria's capital, to the home of the sea ponies, to a battle on the ocean for the fate of the world - all in this long adventure with more innuendo than you can shake your plot at. (Comments are appreciated! Finally done!)

The Great and Powerful Trixie has fled from Ponyville because it's canon. Since this is a fan written story, she returns to Ponyville unintentionally and meets up with Twilight after collapsing on her doorstep. To spoil the first paragraph, both mares already harvest feelings for one another. Hilarity ensues as they try to live together by complete force of the author. Will they ever confess their feelings to each other? If they didn't then this wouldn't be much of a romance fanfiction now would it?
