I've spent the majority of my life tilling the desolate land in which I live. Every day, I wake up to move useless rocks from one location to another. This is an archaic line of work that my family has clung to for generations. It is a dull, grey existence.

Today, I have woken up in a strange room, lying in a bed that isn't mine. I'm surrounded by five mares whom I've never seen in my life. They claim to be my friends, and expect me to bring joy to the hearts of everypony.

Joy? I don't think I've ever experienced this for myself, so how am I supposed to thrust it upon others?

My name is Pinkamena Diane Pie, and I'm not sure what to make of this situation.

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?

One beautiful morning, Twilight Sparkle decides she wants a free salad. After a small amount of theft, assault, battery, and arson, she sits down to enjoy what is sure to be the best tasting salad ever.

...Or she would have, if it weren’t for the Equestrian Intelligence Service locking her up as a potential threat to national security. Now, Twilight must escape a maximum security holding facility hidden deep underneath Canterlot. And to do it, she’ll need a paperclip, a spymare catsuit, an escape plan, and an alliance with the dastardly Drakbog, King of Frogs.

When a noisy flock of crows decides to roost on Twilight Sparkle's library tree, keeping her awake all night and refusing to leave, she eventually resorts to drastic measures to run them out of town. Unfortunately, Twilight realizes too late the terrible truth about crows. They never forgive or forget. And they have allies.

After an unknown accident Twilight Sparkle and Rainbow Dash awake to find themselves sharing the same body! Now they must struggle to hold themselves together as their world is turned upside down. How long can two ponies exist in a single mind? It’s a race against time as they search for answers before it’s too late. When all is said and done, you’ll never look at Twilight Dash the same way again.

Fluttershy has a new computer! Rainbow Dash wants to pull a prank and decides to break her in to the cruelties of the Equestri-net in her own way.

Twilight Sparkle knows better than anypony that an exam is serious business, particularly when the exam in question a final exam. Particularly-er when that final exam determines whether she graduates from the Canterlot School For Gifted Unicorns. But exams aren't always fun. Or normal. Or non-homicidal.

Note: the AI character's voice is funniest when read in this voice from Portal 2:

But then, you'd be mad too, if your stupid brother got drunk and told you that you were adopted...

Twilight decides to go out for a friendly night of drinking with her two friends, Pinkie Pie and Fluttershy, to relieve the stress of planning her brother's wedding and defending Canterlot against the changeling invasion, but not all is as it seems.

A letter arrives in the middle of the night, informing the unicorn that one of her two friends has been replaced by a changeling.
