During a traumatic event, an outsider finds himself flung violently into Equestria. His physical form is warped into that of the inhabitants but will his mentality follow? And even more importantly, will anypony truly accept him for who he is? Take a journey alongside this inexperienced youth as he finds himself in a strange new world with very different customs and tries his hardest to find a place for himself where he didn't before. A pity he can't even remember his name...

Okay, the basics. It's first person almost entirely. Very, very long chapters. I try to wrap them up around twelve to thirteen pages but a few slipped over that, especially towards the end. I'll release them slightly stagnated, as I'll be making final revisions as I go. Character tags are NOT final. I'll add more main characters as they show up in each chapter. Expect an update one or two times a week, probably. I adore reviews and structured, constructive criticism. Even if you just want to say you like it, that's fine too. :) I write stories to entertain peoples, so any evidence I get that it's working will encourage me. I hope you enjoy the story!

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

A Soot-Covered World, book 1.

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

My eternal gratitude to my editor, LordOfTheWrongs, without whom Night's Favoured Child would not be the story it is today.

Now with added TVtropes!

At first glance, Princess Luna's charioteers might appear to be little more than Royal Guards dressed in festive apparel for Nightmare Night. However, there is far more to the story than that - the Night Guards once played a pivotal role in the history of Equestria, and have sacrificed more for their beloved princess than most ponies are even aware of.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

Everypony has a story. Some tell of heroic feats and grand adventure. Others tell of villainy against the forces of Harmony. The story of an average guard, however, is one of obscurity. They live in the background, unnoticed but ever-present.

Silent Knight assumed his tale would be like that of his father's: join the Royal Guard and serve Equestria. He would be just another helmet and spear, part of the rank and file. And that was all he ever wanted.

However, when Captain Shining Armor asked for volunteers to form a House Guard for the recently returned Princess Luna, it was Silent's hooves that stepped forwards to set his new life in motion.

For most of Applejack's life, she didn't know what she was. True, she understood who she was well enough.
But ponies don't change shapes, nor do they get strength from love.
Applejack never thought too hard on it... until the events of a certain wedding brought about some harsh realizations.
Now, with Equestria still reeling from the surprise attack, will Applejack manage to come to terms with what she is? Will she even be able to keep her secret safe?
For if the royal guards don't get her first, the conspirators in the shadows just might...

Zevan was a loyal changeling and always did his queen's bidding, although he quietly questioned why changelings should end centuries of secret but peaceful intermingling with the pony population. After being expelled from Canterlot by the irresistible force of love and badly injured after crash-landing in trees, he had to reconsider his future. Ponies knew that changelings existed now, and the only example of them was Chrysalis' attempt to overthrow Celestia and their attack on Canterlot's population. His kind would be pariahs for the foreseeable future and maybe even their disguises would not keep them safe. A unicorn mare with a broken horn might do the trick though.

There is now a prequel to this story - Prelude To Change I suggest that you read that first.
