Daybreaker: the monster in Celestia's heart, and the age-long mystery of her life. Her friend and tormentor, her companion and foe. Fanatically devoted to their future, yet desiring one horrific to Celestia.

It is growing stronger.

[Complete! With TVTropes apparently!]
Also, apparently, an animated trailer.

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

Twilight Sparkle is brilliant. This is not ego, this is fact. One proven by her latest creation for LunaTech, a personal robotic companion capable of meeting all of its owners needs. But when the robot starts to show signs of developing beyond its programming, Twilight must decide whether she can continue the experiments she's running. If not, can she really justify shutting it down?

Written for Monochromatic's Interwoven Colours contest.

Talks broke down. The unification failed. Hearth's Warming have never occurred. The Great Pony War divided the land, and fears of a prophecy forced the unicorns deep underground and into near extinction.

Almost one thousand years have passed. The curious unicorn Sparkle yearns to breach the surface to discover its many wonders and to search for her missing father and brother, both of whom crossed over many years ago. She is forbidden to leave the safety of her subterranean village of Unicornia until she discovers an orange earth pony washed up on the shores of an underground river. That pony bears one of the six Elements fabled to change the world.

Or destroy it.

Re:Harmony was conceived before Season 4 aired, so some personalities and character relations do not line up with the show's canon.

When Gaberdine is awarded a noble title by Princess Celestia, he soon finds out that his new lands contain several surprises. For starters, there is no land in his new barony. Secondly, his new castle turns out to be a broken-down riverboat. And third is… seaponies.

Baron Gaberdine has a lot to learn about his new barony. And himself.

Fortunately, he has a very young teacher.

Now with a sea-quill (sorry) Drifting Down the Lazy River
