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!)

How would a being like Discord want to be remembered after he's gone? Well, if you're curious, he did actually write a will. To the surprise of nobody, its contents are bizarre and mildly disturbing.

Part of the Borderworld.

Now with audio readings by NDLMongoose and MelancholyIguana.

I was known as Frank DeFontaine. I was going to a Halloween party. I was a pretty intelligent kid, starting my first college term, and decided a little dress-up couldn't hurt.
My buddy Richard got involved, though. And like everything, he took it a bit too far. This time, I didn't say no, though. I really should have.
Next thing I know, we're going all-out on making my Dullahan costume. Because he's my favorite optional boss, and all.
Really shoulda known something was up when that guy behind the counter just so happened to have a sword that fit our specifications perfectly.
Next thing I know, I'm in Equestria. And I'm missing a head.
Sakes, I could use a drink. And a neck.

I'd like to leave it at "Holy mother of-!" but that doesn't capture what I'm feeling!

Pinkie Pie is bringing her big sister Maud around on a tour of Ponyville. While looking around Sweet Apple Acres, Maud loses her pet rock, Boulder. She receives help from Big Macintosh, and the two have a nice, deep conversation.

Thanks to RainbowBob for the idea for this ship.

Now with TWO YouTube Readings! One by Arwhale and one by DRWolf!

Now with a Spanish translation!

In 2185, during his campaign against the Collectors, Commander Shepard discovered a previously unknown species whose origins predated any other race in the modern galaxy. Following a daring rescue from their ancient sanctuary, the Equestrian Herd was brought back into the galaxy where, for the first time in eons, they must walk their own path.

Knowing full well the terrible threat that lingers on the edge of the galaxy, the leader of this newly freed race fights to secure her people’s future while attempting to prepare for the storm on the horizon.

This is her story.

The Discord Association for the Reformation of Villains, Evil Doers, Rivals and Ne’er Do Wells is a support group founded by the God of Strife himself to help former criminals, monsters, enemies of Equestria, and general enemies of the peace reform and reintegrate into society. They haven't been around for long, but there are high hopes for the project.

Twilight Sparkle has been asked to attend, and she has no idea why.

Written for and Honorable Mentioned in the EFNW Fanfiction Contest

(I wanted to add a Sad tag but apparently wistful or sad comedies are just not things that exist on Fimfiction, so be warned.)

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

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."

Now with an amazing YouTube reading by the equally amazing AShadowOfCygnus!

During its two year search for Shepard, the lone Geth traveled across the galaxy, exploring worlds both known and unknown. After a blind FTL jump to escape from an Alliance patrol, it found itself in a previously undiscovered system, a system without a mass relay and completely cut off from the rest of the galaxy. It touched down on one of the worlds, a garden-like planet, with the intention of gathering data on any flora and fauna that may have been present.

Instead, it made a remarkable discovery.
