Twilight Sparkle has spent years as Discord's protege, studying the Magic of Chaos. But when rumors of a strange phenomenon dubbed "Friendship" show up in a small outlying town, the Emperor sends his star student to find out what's going on. Twilight goes with the best intentions and quickly discovers there is more than meets the eye going on in Ponyville...

Inspired by this post on r/mlpwritingprompts, by MetaSkipper. Original version by me is in the comments there.

Continued here!

What does it mean to be immortal? Celestia has lived for too long. Her memories are old. She has seen many ponies, and many places, and many times, and many stars, and many dreams. She wakes one night to find she does not know the ponies and the stars of today from the ponies and the stars of any other day she has lived. She no longer knows what was real and what was only dreamed.

She desperately searches for the one pony she knows could not have been a dream.

During a sleepover at Twilight’s, Rarity takes the opportunity to talk about boys. The girls press Applejack into opening up a little more around them.

But a good girl never talks about that kind of thing…

The sequel to this story: Sweetie Belle and the Quest for Knowledge is now available!

When Sweetie Belle finds a mysterious artifact of a now lost civilization, how will she come to terms with the wealth of knowledge it provides? It says it can be ignored, it says it will never try to influence her, but can an artifact of such power really be so harmless?

Thanks to Malefactory for editing.

The nation of Equestria has been exploring their little slice of the universe for some time now. From launching probes into deep space, to landing ponies on the moon. Sending things beyond the grasp of their planet has become almost routine. However, with every mission into space, there comes a time when the voyage must end. What happens when Equestria experiences the end of a voyage that they didn't begin?

This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

(Sequel to Stardust, familiarity with this is recommended!)
(Proofread by Arzoo!)
(Coverart commission drawn by the amazing KairaAnix!)
(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

(XCOM/FiM Crossover)
(Sequel to Stardust, which I recommend reading before starting this. Fortitude Amicitia and Broken aren't required reading but are supplemental to the storyline)
(Gore tag for blood and violence)
(Alternate Universe tag because of the divergence from canon that Stardust has caused)
(Uses elements of Season 4)
(Coverart produced by the amazing Carnelian!)
(Many thanks to Arzoo, BradTheBrony, Vandenbz and Setokaiva for prereading!)
(As of 03/07/2016, the prereading team consists of Arzoo, BradTheBrony, Noble Cause and Metallusionsismagic!)
(Complete with it's own TVTropes page as part of the Stardust continuity. Could use some updating!)
(Character tags will be added as chapters are added!)

(Possible spoilers in the comments! BEWARE!)

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Sunbeam Sparkle is not a good pony. She might not be pure evil, but she is ruthless, ambitious, and so power-hungry that she would even aspire to usurp Celestia's throne. Worse, she succeeds in manipulating Celestia into not only surrendering rule over Equestria, but her immortality as well.

It is often said that power corrupts, and absolute power corrupts absolutely. In most cases that’s true. Many good ponies have begun with good intentions, but slowly lost their way. However, this is not always the case. A rare few virtuous ponies have the character and strength of will to resist temptation, and are never corrupted by their authority.

Even rarer, there comes a time when gaining power makes a pony better than they were before. This is one such story.

This story is a sequel to Rise of the Phoenix Empress

It has been nearly nine hundred years since Sunbeam Sparkle claimed the throne of Equestria after Celestia’s abdication. In that time, she has forged Equestria into a powerful centralized empire that spans most of the known world. Even the distant griffons and zebras pay reluctant homage to the Phoenix Empress.

In this series of connected one-shots, we’ll be taking a look at life the new Equestria Sunbeam Sparkle has forged, through the eyes of its inhabitants.

Study Buddies: Sunset Shimmer and Twilight Sparkle are the Empress’ co-students. They also rather dislike each other, mostly due to Sunset’s less than friendly attitude. Can they find a way to work together to fulfill the Empress’ high expectations, or will they just end up trying to kill each other?
