[The Gore tag is for the end of Act I and onward. Beware of possible spoilers in the comments.]

Within every one of us, even the best of us, there is an essence of Goodness, and an essence of Evil.

After a freak accident resulting in her mother falling into a coma, Twilight Sparkle put her magic studies aside to pursue medical science in an effort to save her. Eight years have passed, and Doctor Sparkle has successfully concocted the TS8 Formula, a potion that can separate the natures of goodness and evil that lurk within the hearts of us all.

All that remains is a small test to prove that both the Formula and such a separation are conclusive. Everything will be certainly fine . . . right?

(AN: Takes place shortly after "Too Many Pinkie Pies", but before the "Twilicorn era".)

Based on Jekyll and Hyde: The Musical

Starlight Glimmer has finally done it. She has stolen the cutie mark of everypony in Equestria and shown them the path to equality. From her new home in Princess Twilight's castle, Starlight rules Equestria, pushing everypony towards happiness and equality.

But one day Starlight Glimmer encounters a mysterious filly. A filly who is immune to Starlight's cutie mark-stealing magic. A filly with no name, no family, and no past. A filly who refuses to wipe that creepy smile off her face. As the filly begins to make friends with everyone in Ponyville, Starlight searches for a way to beat her. And what does the filly want from Starlight?

She just wants to break her.

WE HAVE COVER ART! 8/3/2016 Check the source for the artist. (permission was given)

The Elements of Harmony have been corrupted by dark magic, taking the mane 6 with them. The mane 6 have been transformed into demented, chaotic, violent mirrors of their former selves, wanting nothing more than to have Equestria all to themselves.

With the two sisters defeated, who will step up to save Equestria now?

Well, Pixel was supposed to, but he's kinda freaking out right now. Give him a minute.

This is sort of a catalogue of my progress as a writer. I started with an idea and little to no skills in the area of writing, and over time, I've gotten better and better. The earlier chapters might be a bit hard to read through now, but seeing how much I've improved is encouraging to me.

Twilight Sparkle was presumed to be dead. Destroyed without even a body to bury, the young victim of a deadly magical surge that claimed the lives of many others along side her. More than a decade later, reports of a violent murder by a pony bearing her name are brought to Celestia and Luna's attention. A trail of carnage leading directly towards Canterlot's doorstep, brought by a pony who strikes without mercy. As Twilight approaches, in service to an unknown master, the Alicorn Sisters desperately try to uncover what happened all those years ago.

The end of every story is always a happy one. Whatever trouble has befallen the mane six is cleared up. Their friendship is only strengthened by their conflicts, and by the roll of the credits, there are no hard feelings. But sometimes that isn't true. Sometimes nothing is resolved, nothing is learned.

Following the events of The Mysterious Mare Do Well, Rainbow Dash finds her own masked feelings stopping her from learning her lesson. Her actions in the past week carry consequences, and soon she finds herself fleeing Ponyville to get away from her troubles. She seeks the counsel of Celestia and Luna themselves, the co-rulers of Equestria, to help ease her pain.

Not long afterwards, Ponyville is attacked by a mysterious new villain. Armed with a powerful trinket granting her the abilities of a unicorn, the white-haired pegasus known only as "Ultramare" has made it her goal to personally see the town in flames.

9 characters, 1 mountain, 11 hours Until Dawn.

After a mysterious blackout stops Twilight and her friends' party on Blackhoof Mountain, Spike and Starlight are sent out to investigate the cause. In the meantime, ponies are going missing and Applejack has to find the kidnapper before it's too late.

Who is responsible for all these occurrences? Is there a murderer on top of this mountain? And what about those shadows they keep seeing from the corner of their eyes?

An Until Dawn x MLP crossover. Had to change most of the plot, or else things might get too predictable.

Oh and the cover art is from wikipedia. I thought it'd look better.

A notebook of grave proportions has fallen into the world of Equestria. Nothing good can come from it when a military prosecutor with a warped sense of justice gets a hold of it. Can one pony along bring the world to its knees? Or will somepony stop him right in his tracks? Unbeknownst to Rarity, the stallion she likes will become one of the most tyrannical of mass murderers in Equestrian History. Fans of Death Note especially should enjoy this continuing Fic.
