“What’s your point Big Mac?”

“All I’m saying, sis, is that it’s ok to let it out. No one’s gonna judge you. I sure as sugar ain't.”

Instead of expressing her emotions Applejack finds it best to hide under a tree.

It was a completely normal day in Ponyville for Twilight Sparkle, or at least, that's what she thought it would be. That should have been her first clue that something was up. She expected it to be a quiet day where she could hang out with her friends, and maybe she'd get a friendship letter in if she was lucky.

She did not, however, expect everypony in town to turn into a flaming racist overnight.

Feedback is appreciated.

How Pinkie's secret ingredient is made...

And it might cost her her life,
Or at least her sanity...

A Cupcakes Sequel
Note: This is a study of what might of occurred had Pinkie Pie been caught after the death of Rainbow Dash. The only part of this story to contain actual gore is Part 2.

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?

Princess Celestia always thought she knew how her kingdom worked. The Unicorns used magic specialized to their jobs. Pegasi flew in the sky and handled the weather. And Earth ponies... Earth ponies... uhhmmm...
Huh. Maybe Princess Celestia didn't know everything about her ponies after all.
Princess Celestia realized this after Applejack came to speak with her about a tax unfair to Earth pony farmers. It was during their conversation that Celestia realized she needed help.
Huh, isn't that odd Princess Celestia has had to leave on emergency business, leaving Luna to raise and set the sun? And hey, is that a new pony living and working at Sweet Apple Acres? I think her name is Sunshine Meadow. Surely, it's just a coincidence. Surely.
