Celestia has a dangerous creature held in the deepest of Canterlot's high-security dungeons. It can create ponies (with full backgrounds and histories) with it's strange and often-times prophetic powers. The Princess does her best to keep it under wraps, but its only a matter of time before it's "creativity" will get out of control.

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

She is Loyalty. She will be the last one standing by her friends, in peril, torture and death.

This is what everyone believes. This is what Twilight and the other Spirits of Harmony, Rainbow's friends, believe. And they took it entirely for granted. After the Mare-do-well incident, Rainbow Dash's Loyalty began to falter. She still felt the terrible sorrow of being deserted by everypony, to be forgotten in the shadow of a greater hero.

Over time sorrow grew to anger. As the powerful bond of friendship crumbles as Rainbow begins to drift away, The others discover just how powerful the Element of Loyalty is, and how its absence might have caused the downfall of the greatest heroes Equestria has ever known.

Mort, also known as the Pale Pony (of Death), has been tasked to take time off from his rigorous duties of reaping souls. Seeking guidance, he is directed towards the town of Ponyville, to learn about the magic of friendship from Twilight Sparkle and her friends. All he needs to do is keep his true nature a secret. That shouldn't be too difficult...right?

Special thanks to Specter-Von-Baren and Pyrite Foolsgold for their help in proofreading and editing this story, as I really needed it. Additional thanks to Pilate, Chuckle5, Unimpressive Vagaries and Admiral Biscuit as well! Couldn't have done it without all their help!

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.

Twilight Sparkle never was a Unicorn and she didn't even know it.
What happens when her true heritage comes to light? Will she willingly embrace it? Or will she be forced to?

Beware of spoilers in the comments!

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?
