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?

Canderous Nord was just a simple pilot in the universe of New Eden, doing whatever he can do to get by, yet he soon finds his way into the ranks of the Gallente Federation Navy. But an expedition through an ancient stargate goes awry, sending he and his division into another part of the universe, one filled not with other humans, but with ponies. Now Canderous, with some help from the new-found species, must find a way to return to their home.

What would you do if you've gone where no mare has gone before, and have no idea how to get back?

Rainbow Dash found herself alone in a strange, magicless world governed by entirely different natural laws than Equestria, ruled by a race who thought themselves the only sentient species in the universe...

Fluttershy must journey to the dark land of Tartaros to save her little bunny, Angel, kidnapped by the Mara, the Queen of the Underworld, with a little help from some unexpected friends.

I can't remember how long I've been alive. I can't remember my birthday. I don't even know my own name. I'd like to think I had a family... but I'm not sure. All these things are meant to be important to me, things I was never supposed to forget, and yet, I have. I have taken shelter in an old castle, in a forgotten city. I do not know why I'm writing this. I suppose just to keep myself sane, but perhaps keeping a record of my activities will help me piece together what happened to the world.

A/N: This is Celestia's immortality, taken to its logical (in my mind) conclusion.

Pinkie Pie has an existential crisis while painting her room. This self-parody is dedicated to Professor Piggy, who once told me that I could write a story about Pinkie watching paint dry and weave it into an incredible psychological journey. Let's see if he was right.

Twilight Sparkle may be the smartest pony in all of Ponyville. She may be able to understand non-linear magical field gains but love eludes her. Can reason and the scientific method shed some light on this mysterious magic? Twilight is determined to try. Surely it is only a matter of applying a proper rigorous series of tests and analyzing the results. It couldn't be any simpler.

A vicious cloud of Hatred threatens Equestria, and only Celestia's greatest General, Twilight Sparkle, can put an end to it. Just a random story that was stuck in my head. It's nothing special, but go ahead and read it. And leave me some feedback. :D (i have no idea how this got to be so popular...)
