Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

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?

Vinyl Scratch and Lyra Heartstrings are vampires, creatures of the night whose civilization has lived in humanity's shadow for thousands of years. They are self-sufficient and prideful, only venturing out of their hidden cities to replenish their stock of blood. But ties to past lives are not so easily severed.

When Lyra catches wind of supernatural happenings in her hometown of Canterlot, she and Vinyl take it upon themselves to investigate the cause.

It was a simple teleport spell. So why did she wake up in the hospital? And how come she was... one pony?

Humans in Equestria? Naa, that's been done to death. What about Ponies in Equestria?

When a clever pony from the human world finds herself in the land of intelligent Equestrian ponies, how will she react?

Twilight Sparkle: a name often associated with magic, friendship, harmony, and most recently, ascendant princess of Equestria.
Nopony, not even herself, could have thought that she would be a changeling.
Especially not a changeling princess.

Rainbow Dash, best pony, fastest flier in Equestria, all around awesome mare, was called upon to help with the wedding of her friend's big brother. And hey, she never leaves her friends hanging! Of course, when it turned out some kind of bug thing had replaced the bride, Rainbow was more then ready to fight. Heck, even after it seemed all hope was lost, the pegasus refused to give up.

So when she saw Shining Armor charge up a final spell, she smirked.

But when that spell reached her and flung her against the wall, her smirk devolved into shock...

My name is Rainbow Dash and today I learned something new. I learned I'm actually a changeling. You'd think that would be something you would already know. I just learned it now when I saw my true self for the first time. How did I come to replace the real Rainbow Dash, and when? And why can't I remember it?

There was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.

The Everfree is a dangerous, yet enchanted place. Evening Storm knew this very well. He had never meant to venture so far into it, yet thanks to a misjudgment here he was.

Stopping for what he hoped to be a short rest under a willow tree, he finds himself in a peculiar situation. Staring at events that long seem past, he's faced with one question:

Can he do anything to change this? For her sake, he has to try.
