One fine morning, Spike woke up early and ran some errands. Then he found Discord putting up a seller's stand, apparently ready to open his own business. One which offers a one-day transformation into anything the user wants. And he apparently had the patience to set up his shop LEGALLY. Twilight and the others brace themselves for the inevitable...

Vinyl Scratch, also known as DJ-P0n3, is one of the most famous DJs in Canterlot. But lately, she's been feeling like something's missing in her life. And then a gray Earth pony mare shows up at her club one night...

Author's Note: I wanted to do something different with the Octavia/Vinyl Scratch pairing. In all the stories I've read, Tavi was the reserved, more quiet one while Vinyl was the party girl. But what if it were the other way around? What if Vinyl was the more reserved one and Tavi the wild girl? This is my attempt to expand on that idea.

Twilight Sparkle, pulling another late night, is finally confronted about by Spike and Starlight Glimmer. She reveals that she's been studying one of the realities she saw, specifically the one seemingly ruled by Flim and Flam. She just can't figure out how those two con artists could be as much of a threat as, say, Tirek or Nightmare Moon.

And then Discord shows up, telling her that she's looking at her information wrong. He volunteers to show Twilight, Spike, and Starlight what that reality is really like...

#1 in the Featured box on 4/25/2016. WOW. I'm... honestly surprised that so many people like this little dialogue heavy stream of consciousness fic. Thank you all very much!

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

For most of Applejack's life, she didn't know what she was. True, she understood who she was well enough.
But ponies don't change shapes, nor do they get strength from love.
Applejack never thought too hard on it... until the events of a certain wedding brought about some harsh realizations.
Now, with Equestria still reeling from the surprise attack, will Applejack manage to come to terms with what she is? Will she even be able to keep her secret safe?
For if the royal guards don't get her first, the conspirators in the shadows just might...

Luna is sent, along with young Twilight, to old Neighpon to try and quell the feuding warlords with diplomacy. And, if that fails, reduce the bloodshed as much as possible. Turns out that Luna is the kind of mare that likes to jokingly flirt and see how far she can go to make the other uncomfortable.
Boy is she in for a surprise.

So the inspiration for a lot of aesthetic and naming is primarily Japanese, however I'm taking from all of the orient and I'm being fairly loose with the accuracy. Translations and terminology won't be exact, don't expect a historical rendition of feudal japan in pony form here fellas.
Will update tags if more of them become relevant.

Being the Deity of Time is tough work. You've got to protect the timestream, save ponies that tamper with time and get stuck in infinite loops.

There's also a lot of experimenting one can get done with the ability to reset the universe each time.

a lot of experimenting.

Point is, she's done a lot, for a LONG time. So, after her latest experiment goes very wrong, she decides to take a vacation.

Back to where she was once known as Twilight Sparkle.

Also, Discord does some things too.

The Witch of the Everfree... a tale that has spread among all who live by the ever illustrious forest, to whom the witch truly is, no one knows apart from the one herself... until now.

Now, forty years after she was dubbed a witch by her race, three little girls stumble through her woods in search of the ever mysterious "witch", what could really happen? read to find out.

Clarifications:
Many have wondered what Twilight looks like and such so to clarify, she does not look like a human female, she retains her fur coat, she is of human height and has hands. The facial structure is more detailed such as where the eyebrows should be there is a darker patch of coat much in the color of her mane.

The story starts a few episodes in, around halfway through season one I would say, some shall stay canon whilst some with alter, I am sorry for this inconvenience.

Twilight is still Twilight in every way, though she has been with little to no contact throughout her life apart from when the Everfree retained people, in such her words would become haggard sometimes so that's why you will probably go "huh" when you first see her talk to the CMC.

That is all for now.

Celestia had a niece once, not an adopted niece like Cadance, an actual biological niece, the daughter of Princess Luna. Sadly when Luna became Nightmare Moon her daughter took her mothers side and led the their forces against Celestia.

Princess Twilight was killed during that battle, or so history tells us...
