This story is a sequel to Past Sins

Side-story to Past Sins - Spike almost lost Twilight to a hangmare's noose, but now Twilight is safe and Nyx is a filly again. Normal life is returning. Still, Spike can't ignore the fact that Nyx just isn't the same as he remembers her. Her temper is more volatile, and, when she gets angry, all he can see is the rage-driven Nightmare Moon of legend.

And thus Spike has to wonder: Is Nyx truly reformed, or is she one bad tantrum away from calling herself Nightmare Moon again?

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?

The daily lives of the royal princesses, often times is pretty simple. Wake up, raise or lower their celestial bodies, hold court, meetings, sleep, and repeat. Oh, and dealing with their infuriating nephew! Overall, things aren't all that easy for them but it's manageable and mundane.

But when an innocent wish came true, both sisters are now facing a new Blueblood. One that can be considered better, yet for some reason, this version seems to have forgotten how magic works and keeps looking at the world like a newborn baby.

So what happens now? Did their wish actually come true? Is it some sort of act? Has he been replaced by a changeling? And what does this new Blueblood mean for Equestria?

Only one thing is for sure, shenanigans will appear and a lot of ponies are about to spit their coffee. Look out Equestria! There is a new Blueblood on the loose, and this one might actually be worthy of the title 'Prince'.

The 'Romance' tag is for events that happen later on the chapters

I made this out of curiosity and intrigue, so there is no need to take too seriously. This takes place during season 8 before Spike got his wings.

Rated ‘Teen’ for language, mild violence, and graphic depiction of cuddling. Ratings could change at any moment depending on how the story progresses.

This story is a sequel to Changeling Space Program

Twilight Sparkle's experimental interplanetary drive has malfunctioned, stranding Starlight Glimmer, Spitfire, Cherry Berry, a changeling and a dragon on a hostile planet in another universe. With limited food supplies, very little magic, no communications with home, and no way to leave the planet, they must survive until somepony rescues them.

Fortunately they crashed right next door to another creature with the exact same problem- a creature named Mark Watney.

They're going to science the buck out of everything- and do whatever it takes to survive Mars and get everybody home.
