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.

All of Equestria is united in celebration for the return of their beloved Princess Nightmare Moon. But when Celestia and everypony else recieve her she's skeletally starved, filthy, and very nearly dead. Meanwhile, while everypony's eye is turned, a lusty Blueblood pursues Twilight Sparkle, intent on adding her bloodline to his own so his family might step closer to godhood. (Alternate Universe, there never was a Princess Luna)

When Twilight is attacked and nearly killed by a madpony claiming to be her brother, she, the Princesses, and the rest of the Elements of Harmony find themselves saddled with a shellshocked soldier who would like nothing less than to end her life. While they help him adjust to normal life, he makes his story known - and what he claims causes them no end of worry.

This is pretty much a self-insert, mostly done for comedic purposes.
After a mishap with an invention of mine, a friend and I find ourselves in the magical land of Equestria. How will the peaceful land of Equestria handle the influx of two humans? Will Jay and I ever find a way back home? Will anyone give this story a fair shot? Read and find out.
Things that actually involve MLP:FiM begin in the second chapter.

This story is a sequel to Inexcusable

She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly, and dirt matted her coat. Most noticeable was her hair; black streaks accompanied its usual multicolored luster. They looked like discolorations in an old photograph.

Worst was the scar across her chest. Her armor covered it, but nothing could hide what it meant.

The tarnished Celestia smiled at Luna. "H-hello, monster. I would say I am glad to see you, but that w-w-wouldn’t be quite accurate."
