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.

Fluttershy is concerned that Discord is too antisocial and insists that he spend time with her friends in an attempt to connect with them and actually become friends. Discord reluctantly agrees.

EDIT: Just to clarify, this is set during the events of season 4, before the finale.

Princess Twilight Sparkle discovers a centuries-old mystery hidden in the Royal Archives. Her investigation leads through layer after layer of deception and misdirection, setting her hooves on a path that seems to be leading to a mysterious secret. Along the way, she learns that some friendships can be very, very strange.

Book 1 of the Alicorn Adventure series.

WARNING: Major spoilers in the comments. Takes place several months after the end of season four. (Not a Da Vinci Code crossover, BTW!)

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

After a long day of flight practice with Scootaloo, Rainbow Dash discovers the filly knows next to nothing about preening and takes it upon herself to teach her.

Warning: May Contain Feels and/or D'aww moments.

Today is Princess Twilight Sparkle’s 500th birthday, and her most faithful student, an earth pony with a familiar name, can’t wait to celebrate!

- This is a story in the Birthdayverse, and you can find the sequel here.
- Many thanks to my faithful Pre-Reader and all around super-duper best pony, Blood Lord. Go read his story, too!

Nopony ever said the friendship between Fluttershy and Discord would be an easy one. The difference in their life expectancies doesn’t help, but that’s a problem Discord can fix with a snap of the talons—that is, until Fluttershy finds out. Discord isn’t one to give up easily, though. He’ll do anything to keep his one and only friend. Anything.

There is now a video review! And still another video review! And Russian and French translations! And there are dramatic readings from Joehighlord and Dr. Wolf! But wait! There's more: Dr. Wolf has collaborated with Meb90 and a team of other talented artists to produce something amazing.

Diamond Tiara has always enjoyed picking on the Cutie Mark Crusaders. But one day, she finds she's gone too far, and everything for her comes tumbling down. But help may come from the most unexpected of places...

Started before season four, and does not take season four canon into account.

This story is 100% Diamond Cutters Approved!
Note: If reading this inspires you to write your own Diamond Tiara fanfics with similar premises, send me a link, as I'd love to see them.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

Twilight gets a feeder to study birds.

She also bought a ton of seeds for it.

While she's frustrated at the fact her supply seems to be disappearing into thin air, she's about to realize that she has a much bigger problem on hoof.
