The ever-helpful Twilight Sparkle sets out to design a compound to help increase brain activity in those who have a willingness to learn, but have trouble grasping difficult concepts. After acquiring a test subject in Rainbow Dash, the results are indisputable! Rainbow grasps new ideas and theories faster and more completely than ever before! But, how smart is too smart?

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.

This story is a sequel to Celestia's Tiny Student

(Title changed from "Ponyville's Tiny Librarian" for reason pointed in this blog )

Twilight Sparkle is a one-kilogram pony the size of a large rat, shrunken by Princess Celestia following her entrance exam to the Celestia’s School for Gifted Unicorns to ensure that her power surges would not pose a danger to the ponies around her.

She’s spent thirteen years full of hard training at her new size, facing the life-threatening experiences that came with living in a world of giants. To survive those thirteen years of hardship and joy, of learning and adventure, and of pride and humility, Twilight has challenged herself to be stronger, to overcome any obstacle.

Now that tiny Twilight is on her way to Ponyville to oversee the preparations for the Summer Sun Celebration, how well will this miniature mare fare outside of the confines of the castle? How will the other Element Bearers react to her? How will Nightmare Moon react to the tiny unicorn? Is Twiny prepared to face Ponyville, and, more importantly, is Ponyville prepared to face her?

To celebrate the release of this sequel, I created a group called “Twinyverse” for all fans of this story where you can talk about it and track all side stories with ease.

The princesses gave their magic to Twilight to prevent Tirek from stealing it. As a result, they end up stuck in Tartarus.

Marvelous place, Tartarus. Really brings ponies together. The fact that things manage to go downhill here says a lot about the wonders of family and alicornhood.

This story is a sequel to The Unchosen One

Trixie has wings and a horn, but she isn't a princess yet. With Equestria's political situation fragile following the events of Tirek's attack and subsequent defeat, she has to hide her status from everypony. At the same time she has to learn how to control these new powers and try to earn the respect she desires.

Of course this would all be easier if there wasn't someone working against her from the shadows.

You don't need to read The Unchosen One before you read this, but since this is a direct sequel it would be good so you know how and why Trixie got those wings. It would also be good to have seen the ending of season 4. If you haven't yet, don't read the bit above where I mention Tirek. Don't read that last sentence either.

When Scootaloo falls off her scooter, Discord "rescues" her, turns her into a cyborg and makes her watch bad fanfic. Parody of "Robot Chicken", and also of a lot of bad fanfics. Many other parodies may turn up as well.

Added the Sex tag due to all of the innuendo in "Harpstrings. Lyra Harpstrings", but there's no actual sex in any of these skits.

New cover by Woolly!

Just give in to her, Trixie. It will be much easier on everypony...

(Your clop is in another castle.)

Pinkie Pie has a spare of everything. Even emergencies. You know, in case of emergency emergencies.

Life is full of surprises. That is a known fact. However, you always expect some kind of minor surprise, like your train arriving a little too late, or your ice-cream having vanilla taste rather than strawberry. But sometimes, life will give you surprises you could never predict. For Fluttershy, it was three little foals. But not her own foals, or even orphans. Three little foals that used to be her and her friends' most fearsome and dreaded foes.

Sombra, Chrysalis and Nightmare Moon.

Will Fluttershy's nerves survive this onslaught of misadventures? Will she keep the three villains hidden? Will she even become friends with them? Why do I sound like a narrator to a bad criminal drama? Don't think or try to answer those questions, just go ahead and read!

Trixie has returned to the only life she hasn't failed at, rock farming. When her old rival comes to help her make amends, she's thrust into an adventure she doesn't want to be on, but it may be what she needs to reclaim her confidence as the Great and Powerful Trixie she once was.
