Just about everypony in Ponyville knows Scootaloo. She's your normal, carefree pegasus foal who crusades for her cutie mark, zips around town on her scooter, and looks up to her idol Rainbow Dash. But what if that's not all there is to her? Scootaloo worries that her friends will find out that she's not the foal they know and love, or that she's not even a foal at all. But, when her secret does come out, their reactions might surprise her.

What if ponies replaced humans in the Mass Effect universe? Will Commander Sparkle save the day like Shepard did?

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?

October, 2179. The USCSS Alhambra has discovered a distant planet amazingly rich in precious ores and minerals designated as "LV-1349."

Mining goes rather well for about a week or so.
Until the entire crew of the Alhambra vanishes.

With a massive payload worth billions waiting to be towed back, the United States Colonial Marines are called upon to investigate the missing crew and bring the Alhambra back to Earth. Their orders also include avoiding the local equine populace as much as possible... but as we all know, sometimes even the best laid plans can go to waste.
