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.

Twilight is an intelligent mare, and always has something to say. But when a group of bizarre creatures shows up at her library offering life long service and devotion, for once she's at a loss for words. Which is too bad, because she'd really love to ask: what's a human and why are they so weird?

Wishing to celebrate her sister's return to Equestria, Princess Celestia revives a competition long-forgotten to modern ponydom: a race over the kingdom's oldest road. Twilight Sparkle and her friends sign up to participate in what they think will be a fun diversion, but will their individual reasons for running breed cooperation or conflict?

Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

When a mishap causes two para-dimensional weapons to colide with one another, RED Team's Pyro is sent flying from the Team Fortress 2 universe into the alternate universe of My Little Pony, where he is almost instantly discovered by Lyra, who shelters him in her home.

Having him hidden in her small townhouse isn't easy; keeping him from setting things on fire, teaching him that not every cart that passes by is cause for alarm, and that blue ponies are not something to be suspicious of.

However, with Nightmare Night soon approaching, Princess Luna feels that there may be something more sinister riding on the coat tails of Pyro's grand entrance; the first human to ever set foot in Equestria some thousand years ago...

Scootaloo is a small pegasus with big dreams, one of those dreams is to be even more famous than her idol, Rainbow Dash. To get there, though, she needs to do a bit of growing, and first of all she needs to learn how to fly. A new invention from her friend Doctor Whooves may get her there in no time at all, literally before she knows it.
