Princess Luna has been through a tough life. A thousand years ago she could not control her jealousy, envy and rage and became the infamous Nightmare Moon. Then, she spent a thousand years on the moon, only to return, still as Nightmare Moon.

However, despite everything she has been through, her return to Equestria was warmly celebrated. Princess Luna is a pony that everypony loves, and she is completely forgiven for everything that's happened.

So, when Princess Luna is suddenly and unexpectedly killed, the entire nation of Equestria is thrown into grief and despair. Ponies everywhere find themselves unable to deal with the tragedy.

But the worst hit is Princess Celestia herself...

A thousand years is quite the generation gap, so Princess Luna decides she has to get with the times. However, this isn't quite as easy as she thinks it will be...

While experimenting, Twilight's new teleportation spell goes awry, sending her careening into a different world, just in time to take part in a fantastic ritual called Heaven's Feel. Twilight must adapt to the world of humans and take part in the vicious conflict that is the 4th Holy Grail War as a Servant alongside her equally reluctant Master. The duo must contend with powerful adversaries and survive the subtle machinations of the Magi determined to win the Grail at any cost. Can Twilight overcome her unwillingness to take the lives of others? More importantly, should she? And is there any way for the displaced Unicorn to return home? Trapped, alone and in a different world and surrounded by enemies on all sides, does the Magic of Friendship still hold any hope for Twilight?

A crossover with Fate/Zero.

The Medallion of Light and the Medallion of Shadow are some of the most powerful yet obscure artifacts of antiquity. Created by a now-vanished cult of assassins, the two devices together give their bearer the incredible power to walk the worlds with but a single step.

Nefarious forces are closing in on both artifacts, and very little stands in their way. Heinrich Himmler's agents covet the medallions for the greater glory of the Third Reich. Ahuizotl's simply want their master to get what's coming to him: the world, and everything in it.

With the fate of all good people and ponies in doubt, one thing's for certain: saving two worlds would be one hell of an adventure. And if adventure has a name, it must be Daring Do… or is that Indiana Jones?

Will our heroes win the day? Find out in... Daring Do and the Medallion of Shadow! Or, Indiana Jones and the Medallion of Light!

NOTE: there will be some violence in this story, but nothing more than you would expect to see in an Indiana Jones movie-- so I didn't check the "gore" content box.

Thanks to this stupid thing I've had the Indiana Jones theme song stuck in my head for like the past four days and I am about to claw my eyes out AAAAAAAHHHHH @_@

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!

This story is a sequel to The Rainbow's Surprise

On the day of Fluttershy and Rainbow Dash's wedding, Princess Celestia left Twilight a message saying that she should prepare herself if something happens. The next morning, Twilight awakens to find that all of Ponyville has succumb to a blinding fog. She must now travel a monster-filled town in search for her teacher and friends and try to return Ponyville back to the way it was.

It's lunchtime in Ponyville, and Twilight Sparkle's stomach is calling for something with a little more flavour than what she usually feeds it. How will she and her friends react, though, when the lavender unicorn discovers that there is no place in Ponyville where a pony can get a decent burrito?

Twilight Sparkle just can't find enough time in the day. She has to study friendship for the Princess, hang out with her five friends, and juggle her own hobbies and interests besides. But when a novel solution presents itself in the form of an experimental new spell, will it solve her time crunch, or will she be distracted even further?

An idea which wouldn't stop bugging me til I wrote it down. After Albert Wesker is defeated,he finds himself in a strange land. A strange land known as Equestria. How will a supposed god deal with the power of friendship and magic? Rated T to be safe.
