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injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her.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!)

(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.

(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."

"I have sworn upon the altar of God, eternal hostility against every form of tyranny over the mind of man."
-Thomas Jefferson

Three hundred years ago, Equestria tried to assimilate Earth.
They failed. They fled, rather than face justice.
We moved on. We conquered the stars, we made a civilization that spans across the infinite void. We built true harmony between species.
We thought we'd seen the last of Celestia, but as a desperate mobile colony on the fringes of known space came to discover, we were wrong.

It is time to finish what was started by our forefathers.

Based on TCB: Not Alone, by Starman Ghost.

EDIT: Following Starman Ghost's deleting of Not Alone, I've replaced the above link with one leading to a PDF file uploaded to mediafire.

EDIT (14/04/2014): The character of Evening Star was originally created by Starman Ghost. I am using her without his permission.

Twelve thousand years ago, humanity was driven into a war with an unknown enemy. Fire rained from the heavens and the sky turned dark as the sun dimmed. Acid poured from the clouds and a plague was unleashed upon mankind: A virus that caused men to turn on one another. A disease that forced man to fall to his knees and beg for mercy. A pathogen that ravaged man’s civilization.

And when humanity lost all chances of reconciliation, all hope of keeping their loved ones safe, they pulled the plug, three hundred souls left Earth while sacrificing their only home to the angel of the enemy.

In the twelve millennia since the Great War, all traces of humanity have been wiped from the surface of the Earth. In man’s rightful place now are a multitude of sapient species. For twelve thousand years, these animals have lived in peace and harmony, man reduced to nothing more than but a myth, a folk tale, a legend.

But word has spread across the countryside. Word of forgotten beasts that still walk the western wastelands. Creatures able to bend the world to their will without the help of magic. Creatures said to be older than time itself.

Teen for language, and dark moments. Character tags will be added as the story progresses

This story is a sequel to The Best of All Possible Worlds

In school, everypony learns about the official history of Equestria, the acts of heroes and villains that made the world what it is today. But at home, everypony learns another, secret history, about how their family and theirs alone is at the center of Equestria's history, and how without them, the world will fall apart. This Hearth's Warming Eve, Twilight Sparkle and their friends will share their secret histories, and in this way discover that the bonds between them reach back far earlier than Rainbow Dash's first Sonic Rainboom.

This is a follow-up to my earlier story, "The Best of All Possible Worlds". That story was set centuries in the past, while this story is present day. If you're wondering where the humans came from, see another side story that is otherwise unrelated to this, "Parade Coverage". Despite that, I expect that this story stands alone. The story's set in an alternate-universe Season Three that branched off early in Season Two.

A recent plague of freakishly strong thunderstorms has been ravaging Ponyville's borders, and somepony has to put a stop to it. Twilight Sparkle, Applejack and Rainbow Dash must venture into the depths of the untamed Everfree forest, further than ever before, and find the source of these natural disasters... and in so doing, they uncover a being that is beyond all natural law.

Set in the early days of the mane six's friendship, before discord's redemption, and before the King of Shadows or the Queen of Lies were struck down. Don't let the cutesy prologue fool you... this story is a bleak and foreboding glimpse at a fragment of Equestria's ancient history. The story is complete, and chapters will be released every one or two days.

The Lone Wanderer has been known as the man who shouldered the nightmares of every man, woman and child in the wasteland, so that they may live. But when the Wanderer was once again abducted by aliens, he found himself falling, quite literally, into a whole new wonderous world, untouched by the horrors of nuclear devastation.

He has been facing other people's nightmares constantly for almost a decade, it was high time he was allowed to wake up.

Meanwhile, the ponies of Equestria are baffled by a strange object that fell from the sky.

Fallout/FIM crossover. HiE. T for violence and some language.

Now with a TVTropes page!

Two hundred years have passed since the discovery of the purveyor and the events set in motion by Celestia's endeavor to save her own world. Now, the purveyor has returned from the void and their world will change, for the better... or for the worse.

This is the sequel to The Watcher, it is advised to read it before reading this.

A big thanks to Lord Destrustor for editing. Go check out his work, his stories are definitely worth your attention!

Discord has once again escaped. While trying to escape the mane 6, he realizes that his chaos magic won't be enough to defeat The Elements of Harmony. So he opens a gate to a new universe. Mane 6 follows him trough the portal, unaware of his plan.

Now, stuck in an universe that is so like, yet unlike their own, can Mane 6 find Discord and stop him before he unites the forces of chaos under his rule? And how do they deal with very different versions of their own?

Reading my other stories is recommended, but not necessary. However, I suggest reading at least The History Of The Human War to understand what "The War" refers to.

After The War - Luna Aeternal is recommended, but not necessary. It details the events of The Lunar Crisis.

My Little War Orphan is not necessary.

Big thanks for Biker_Dash and xoid for beta reading and general help. You're awesome.
