To Twilight Sparkle and Princess Celestia, it is a simple surprise visit to Canterlot. To the ponies of the Equestrian Civil Service, it is twenty-four hours of chaos, politics, weaponized dessert, politics, underhooved manipulation of media, politics, and things batrachian and tentacular. Who said bureaucracy isn't exciting?

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?

Where did Spikes egg come from? Why did Celestia have his egg in the first place? Why was she using it in a test to find a pony she would eventually groom into a Princess?

In shock over the loss of the Golden oaks library and believing his friends are gone, Spike has something trigger within his little dragon body that he had never felt before....or had he?

After rising to stardom following Rarity's first, poorly received fashion show, Vinyl Scratch struggles to adapt to the higher class of life celebrity status bestows. Her personality and own moral values do not mix with the fake, corporate ideals of her agent, and her sponsors are only interested in her as long as she conforms to their expectations. Her life is barely her own and soon she will have to decide what's more important; her existing relationships, her fame and fortune, or perhaps something unexpected in the form of a refreshingly grounded Canterlot Elite who just invited her to breakfast during the Canterlot Music Convention.

A Vinyl Scratch x Octavia story where the two Ponies involved don't instantly form a romantic relationship the moment they meet, and instead allows it to grow over time with good old character development.

All criticism is welcome, and of course some spoilers follow in the comments below so please read cautiously.
Mega thanks go to Cruel September for her fantastic cover art for the story. Go show her lots of love, she's an amazing artist. http://cruelseptember.deviantart.com/

Twilight asks Zecora why she rhymes.

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.

Distance can drive us apart. It can also bring us closer together.

After all is said and done, and the ponies have gone their separate ways, the only way they have to keep in touch is through letters.
