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.

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!

In the midst of Equestria's most recent age of peace, just after Princess Celestia puts the finishing touches on her latest gift to her subjects, Twilight Sparkle appears with a strange question about an obscure beast. It's obvious that something else is bothering Celestia's most faithful student, but what?

Filthy Rich has a problem. His daughter, Diamond Tiara, keeps breaking her promises to treat her classmates with more respect. In fact, she doesn't even seem to really understand what a promise is. Since punishing her does not seem to have much effect, Mr Rich is forced to consider a more creative parenting method. But how can he make such a spoiled, materialistic little filly as Diamond Tiara see the value of a promise?

With money, of course!

Now has a dramatic reading on Youtube! Kudos to DRWolf.

Diamond Tiara has always enjoyed picking on the Cutie Mark Crusaders. But one day, she finds she's gone too far, and everything for her comes tumbling down. But help may come from the most unexpected of places...

Started before season four, and does not take season four canon into account.

This story is 100% Diamond Cutters Approved!
Note: If reading this inspires you to write your own Diamond Tiara fanfics with similar premises, send me a link, as I'd love to see them.

Today is Princess Twilight Sparkle’s 500th birthday, and her most faithful student, an earth pony with a familiar name, can’t wait to celebrate!

The mane six take shelter in a place that is, for now, safe from a disaster occurring outside.

This gruesome tale of violence and death is not recommended for colts, fillies, or the faint of heart.

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.

*6-16-2017 Edit, added Rainbow Dash tag because it triggered knighty.*

Fluttershy is concerned that Discord is too antisocial and insists that he spend time with her friends in an attempt to connect with them and actually become friends. Discord reluctantly agrees.

EDIT: Just to clarify, this is set during the events of season 4, before the finale.
