Twilight Sparkle has a secret. Not one that can change the world or overthrow the Princesses. But it is one that hangs over her head every day. One that colors her every thought and action. Or at least, that is how it seems to her. But when a rainbow colored pegasus asks her out on a date, will she learn to see past it, or will her secret tear apart a budding relationship?

Inspired by the excellent fic Asylum by Daemon of Decay.

Takes place before "A Canterlot Wedding."

There are many legends whispered among the ponies of Equestria, but none are stranger than that of the metal man that fell from the stars. Legend has it that the metal man's suit of armor still exists to this very day, slumbering the centuries away in the Canterlot Archives ...

Takes place during the season four finale.

Here's some quick background info on what you need to know, seeing as the 40K universe is huge and no one can be expected to know everything.

The Space Marine chapter involved in this story is a little known chapter known as the Celestial Lions, who are a descendant of the Imperial Fists. They were targeted for destruction by the Inquisition after defying them on an Exterminatus that was due to purge a world the Lions had fought for and saved. They fought during the Third War for Armageddon mainly, and during the fighting, they were reduced from 950+ battle brothers to just 96. Their numbers are even lower now, due to events that will be explored during this story.

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?
