Equestria has been a land of peace in a world that has slowly forgotten that their plowshares were once swords. But that peace is far more fragile than at first it appears, and when the world races towards war, only two sisters can stop the seemingly inevitable.

But there is a cost to dealing in power and influence, and with long life and responsibility comes great sorrow. As the warclouds grow dark and heavy over an unprepared world, two sisters must face their own memories of loss and prepare their young counterparts for what may come.

Loosely apart of the Songverse/Nightverse. No knowledge of any of the stories in that continuity is required to understand this one.

Inspired by KnightMysterio's take on the Nightmare-Timeline in the story Context

The Princess of the Sun has fallen, the Queen of the Night now takes her place.

To the surprise of many, Nightmare Moon isn't evil. Or insane for that matter. She is attempting to be a queen that can properly rule a nation she has not seen in a thousand years. Some will try to aide her, others will attempt to thwart her, but the Wrath of the Night is something not to take lightly.

However, Celestia may have made a mistake in letting Luna fade from history and the only mention of Nightmare Moon become a demonized fable- no one would take that very well in her place.

Features: Twilight reluctantly helping a Sane and Noble NMM, curious and confused guards, and ponies being reminded of their lost history.

We all know of how Princess Luna fell victim to Nightmare Moon's influence. We all know of how she returned and how she was saved by the powers of the Elements of Harmony, and how her sister Celestia was overjoyed that after a thousand years her sister had finally returned to her. The question is though, why did Celestia allow her beloved sister to be forgotten by her subjects?

This is the version of the story where that never happened. This is the story where in her grief, Celestia never let her ponies forget the princess they drove to darkness with their and her own neglect. Where she made sure that everypony remembered the day that they lost their guardian of the night. How would the story have panned out with this setup?

(This story is actually inspired by the story The Return of Princess Nightmare Moon by Aegis Shield. This is by no means a copy though. The story just got me thinking about the fact that Celestia really did in a way let ponies forget their was ever a Princess of the Night or that she was her sister. Hope you all enjoy.)

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)

This story is a sequel to Celly's Day Off

Luna wants to do well with her role as Equestria's second princess, but she doesn't particularly give off a good impression... especially since she has been gone for a thousand years. Now she's handling wary citizens, paperwork, and of course, dreamwalking.

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!

On the eve of the Summer Sun Festival Celestia has gone missing, and it's up to Luna to find her. What awaits Luna, however, is not only her sister, but a long awaited confrontation of her past.
Luna may have been able to avoid speaking of her imprisonment for this long, but like her term on the moon, nothing lasts forever and she must finally talk about those one thousand years. It seems though, that Celestia isn't acting how she would expect.

Authors note:
On the story: I had the idea (most likely unoriginal) of writing a story where Celestia and Luna finally acknowledge what happened so long ago when Celestia entrapped her own sister on the moon by herself. I went under the assumption that Luna was conscious the whole time, and the Alicorns being ageless, also immortal, hence her survival there. I wanted to add the twist in terms of behaviour of the two, and I honestly can't claim to know a huge amount about psychology but I've done my best.

Generally:
This is my first attempt at posting a story on FIM Fiction, and I will warn that I had no pre-readers, this is mainly to finally get this somewhere where it can be read since it's been sitting uncompleted in storage for a while. As I add to it I'll upload 'chapters', though it is only a short story.

By all means be critical, but keep these points in mind, I am also by no means any kind of 'trained' in writing. I enjoy writing from time to time and this is the result. I hope you enjoy!
