Discord's the only creature in Equestria who can recognize the human for what he is -- not the long-lost Seventh Element that never actually existed and couldn't have existed before the human arrived, but a meta-reality warper, an entity far more powerful than Discord with the power to warp the minds of all around him and the very rules of magic to make sure that he's always the Big Hero. And the role the human's assigned to Discord is the Villain to beat down or kill.

Pre-reform Discord's fine with being the villain. But on his own terms. Not dancing on some alien interloper's puppet strings.

Without friendship, or even allies, Discord's going to have to find a way to defeat a creature who can alter fate itself and who can even mind-control him. Or he may just end up worse than dead.

Trigger warnings: Mind control (magically induced love, magically induced friendship, magically induced stupidity, Discord being Discord), noncon/dubcon (magically induced love, other forms of highly dubious consent), rape (female on male), violence/gore (mostly against Discord), literally everything in chapters 19-21, humans not being presented as unilaterally wonderful and superior to ponies and/or draconequui.

The Shaper is a smith of unparalleled skill, her creations the most sought after in the fallen world. When a pony named Lyra comes to her with a unique commission she has to put all her skill to the test to craft a weapon of great power. For Lyra's goal is not an easy one, and it is not just any weapon that can kill a Dragon.

A story inspired by this and this image, as well as this challenge by CDRW (whose fic A Still More Glorious Dawn Awaits is quite good).

Hanna, the CEO of Hofvarpnir Studios, just won the contract to write the official My Little Pony MMO. Hanna has built an A.I. Princess Celestia and given her one basic drive: to satisfy everybody's values through friendship and ponies. Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

Rarity has risen to the highest stretches of the fashion business and high society, but she's found that not all is as it seems. In the corners of cocktail parties all over Equestria, dark conversations are found. Eventually, Rarity can take no more of this, and begins reporting back to Celestia in secret while delving deep into a world she had no idea was so intertwined with her life's goal.

How much of herself is she willing to give up to protect the throne and, more importantly, Twilight Sparkle? The life of a spy is a dangerous one indeed.

A canon story in the Rites of Ascension Expanded Universe! Artwork by Violet Squiggles. Author's Notes, including proofing credits, can be found here.

In an Equestria without the Princesses or the guidance of the Elements of Harmony, Twilight Sparkle is a researcher on the cusp of her greatest discovery and simultaneous fall from grace while finding love at the same time.

Initially written for the May/June Twiluna contest. Proofreading and idea-seeding credit goes to Pearple Prose Rated Teen for language and implied sex/violence.

[Complete] Celestia awakens to see an empty world, white sandstone stretching the horizon. She wanders the world as she builds it from her imagination, filling it with life, but as time passes, the world that she created begins to seem like little more than a lucid dream, conjured from the dust.

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?

This story is a sequel to Triptych

The war touched everypony, even those far from the fighting. Compass Rose was affected more than most when gryphons appeared far behind the front lines, and the aftermath left her unwillingly in the company of an enemy soldier.

Set in the same universe as Off The Edge Of The Map, Apotheosis, and Triptych.

This story is a sequel to Dusk and Dawn

The Dawn Militia and Nightmare Moon's armies continue to wage war across Equestria under the eternal night. The six bearers of the Elements of Harmony–Fluttershy, Rainbow Dash, Applejack, Rarity, Pinkie Pie, and Trixie–have been blessed with extraordinary powers, with which they lead the Dawn against the tyrant and her reluctant lieutenant, Eclipse.

But it's hardly easy. After all, what place does harmony have on the battlefield?
