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!

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

2022 REWRITE IN PROGRESS

After being rudely awoken from Cryo-sleep, John-117 finds that the Forward Unto Dawn has been sucked into a gravity well, causing it to fall towards an unknown planet. In the crash, he is separated from Cortana and falls alone into the Everfree forest. In addition to this new complication, old memories from a scarred and tragic past haunt his dreams, putting his remaining sanity on edge.

However, he has little time to ponder these thoughts, as he encounters the planet's... peculiar... inhabitants.

First 19 Chapters proofread by Bravo 539 and Shadownamesto.
Credit for the intro sequence goes to Blaze Spectrum.

Current rewrite will not necessarily follow the old story but certain events and details may be reused.

It has been several months since the disappearance of Twilight Sparkle..

One night, after watching her sister raise the Moon and set the heavens alight, Princess Celestia begins to bed down for the night, only to be interrupted by portal forming in her room. From out of the portal comes none other than Twilight Sparkle, garbed in strange armor.

Princess Celestia, along with Luna, Cadence, and Shining Armor, are overjoyed by the Element of Magic's return, but are justifiably curious as to where she had been and what she had been doing. And so, Twilight begins her tale. A tale of survival against impossible odds. A tale of a people fighting for the most basic right of all sentient beings. The right to exist.

IF YOU FAVE IT, LIKE IT!

A few days ago, RC-1207 "Sev" was pounding a Seperatist ship with Wookie turbolasers when he was overwhelmed. Now he's in a prison camp a few lightyears away. His cellmate is a male quadruped calling himself "Big Macintosh". He doesn't know where his brothers in Delta Squad are, or even where he is.

RC-1000 is the newest member of Tau Squad. Or was, rather. After the rest of Beta Squad was killed in action, he was assigned to Tau, who had just lost their own brother. They were tolerant but distant, and on his second mission with them the "new guy" got captured. Now he's sharing a cell with a female quadruped named "Octavia".

They're going to bust out. And as they try to adjust to the thought that they each might be the sole warrior on the planet, they will think more than a clone, even a commando, normally would. They will fight to defend their new friends. To defend aliens that care about them in ways they haven't experienced as mere soldiers.

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?

A Miralukan Jedi Master known as Damaya Tadro was running, running from the New Order that was hellbent on exterminating Jedi from the galaxy. She finds a previously completely unexplored sector of the galaxy, determining that it is a good of a place to hide as any, but is thrown off guard as her ship, the Imaharo, is brutally thrown around. After a dramatic and fiery crash she finds herself on a strange new planet, perhaps even in a different galaxy!

When Princess Celestia faces a harsh choice to execute an innocent and virtually harmless changeling, will she be able to go through with the notion of taking the filly's life, or will sympathy overtake her moral alignment?

*In this story, the changelings are based off of Season 2, so it's as if they've never given love freely. Sept 4th, 2017

After GLaDOS is uploaded into a potato battery, Wheatley humiliates the AI even further by uploading her into a project that was abandoned by Aperture a long time ago. In the blink of an eye, she finds herself in a deformed body of flesh and bone that resembles an equine, and is just as powerless as one too. It comes with all of its needs and bodily functions as well. To make matters worse, she's trapped in a land full of insufferable creatures that just want to make 'friends.' Will GLaDOS' cold, sadistic sense of humor and morals get the better of the ponies? Or will they peel away the once artificial being's metallic shell and find that there's a softer side? Probably not, but it's worth a try.
