Gilda has returned to Ponyville with one thought in mind...REVENGE!
Still smarting from Rainbow Dash's rejection, she decides to reveal the pegasus's darkest secret to all of Ponyville, one she believes will ostracize her from everyone she cares about...
Little do either griffon or pegasus realize that this revelation will not go quite as expected.

First installment of Discord's Evil League of Evil

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.

*6-16-2017 Edit, added Rainbow Dash tag because it triggered knighty.*

I'd heard about the TV show My Little Pony: Friendship is Magic from my college roommate who is way too into the show. Disturbingly so, actually, but good gravy I would never watch the darned thing! What am I, five? I've got better things to do with my time than watch a silly little girl's show. However, that didn't stop... something from transporting me into the world of the show, so here I am... in Equestria... trying to get home. This is gonna be interesting.

Special thanks to GuyFace, Jack Kellar, Storm Shaker, Spiffy McSquee, and Goober Trooper for helping me with this one!

It seems some ponies find Fluttershy's carnivore pets distasteful. A day of care-taking quickly becomes an extended look at the Equestrian penal system when she is caught feeding animals to other animals.

An unabashedly silly story.

Rated "Teen" for repeated references to murder, but it's silly murder.

There comes a time when the light must go out; but how do you know if you've burned brightly enough?

At Celestia's behest, Twilight Sparkle arrives in Ponyville to prepare for the Summer Sun Celebration, and potentially the return of Nightmare Moon.

Her preparations will be anything but easy. The stallions in charge of the festivities all seem to have taken a "romantic" interest in her, and every one of them is terrible at flirting. Really terrible. Really.

T for innuendo/creepy behavior. Thanks to Sereg for prereading and to Midnight Rambler for helping with the first draft song sequence. Thanks to Posey, Jetto, Blank!, and Kuroi Tsubasa Tenshi for editing (Plus three other anons who didn't give me their fimfic names). Especial thanks to whatmustido and ocalhoun for nitpicking the hell out of this mess.

If Celestia is God, then who are her Angels? Based on Cupcakes by Sgt. Sprinkles: In the aftermath that follows the tragedy at Sugarcube Corner, the Elements of Harmony are lost and broken. However, one night, Luna visits Twilight's dreams to inform her of a powerful resurrection spell. When Dash returns, she isn't the pony that her friends remember and what's more, an 'angel' has followed her into the living realm.

The local crime syndicate sees Miller's lack of ID as an advantage. Before too long, our poor former human is eyeball-deep in the scum of Canterlot. Forget going home - the challenge is trying to stay one step ahead of police, criminals, and a pair of persistent mares.

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?

As far as great ideas go, Twilight stumbled across the best one of all - throwing Pinkie Pie a shocking, frightening horror birthday surprise party! But as the six friends walk into the old dilapidated house on the hill, and the moon rises high above them, pranks turn sour and tempers boil, and the six friends find out that perhaps, the best ideas might not be so great after all. As the gang succumb to the dark horrors of the house and fall to machinations of their own design, Equestria gains another sordid legend to tell.
