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)

(Coverart produced by the amazing Carnelian!)

(Possible spoilers in the comments! BEWARE!)

This story is a sequel to Poniocracy

This story is required to be published so that links in the main story work. This compilation will probably not make sense, unless you read: Poniocracy PLEASE IGNORE THIS UPDATE (sorry potentially excited followers looking for new content).

Info: Published stories will all keep their links. These are just to make things easier for me. I really should have done this a long time ago. Also fair warning: Some of these side stories are incomplete. I may not even finish them unless I have time. That's why they're side stories, they're optional.

The Story of the Gorlians and Equestria
The Gorlians and Ponies Make First Contact - Things Go Well
The Gorlians have finally decided to make contact with Equestria, when they find a human among the populace, the situation quickly devolves into a political nightmare that could only be solved by the banishing of an entire race to the moon.

Why Emergencies Should Be Handled Calmly
You don't want to end up burying dead bodies, do you?
Why it's a good idea to remain absolutely calm when dealing with dead bodies.

Why Emergencies Should Be Handled Calmly II
Why it's good that Twilight learned how to apply first aid before trying her hoof at autopsy.
Sometimes, knowledge is a burden.

Blue Pill
David knows that taking the Red Pill is a huge mistake.
Sometimes, just take the Blue Pill.

David's Nightmares
David knows that pissing off Twilight was a huge mistake.
David don't sleep, don't blink. If you blink, she'll get you.

Robot Manticore Attack
Robot manticores are no joke. Until they are.
Twilight, I need a medic here. No, not Dr. Staton. No, not you either.
You know what?
Nevermind.

The First Law
Don't be a bad robot. Also, kill all the humans.
Robots, they're kind of like people, except a little more sarcastic.

Discordant
David wasn't David, Discord was David, Discord was being Discord, because David wasn't Discord.
Sometimes you can take a prank a little too far.

A Dated Journal Entry
Writing in a journal to express your feelings can be difficult. The task is onerous but fulfilling. Personal thoughts and opinions clash and meld together, but you come out stronger because of it.
Twilight writes a heartfelt note to her Diary. She hasn't kept up with it for a long time. It's nice.

McQuestria
Where you can have all your fast food craving met.
Remember kids, fast food is bad for you, meat is bad for the Earth and they're both addictive.

McQuestria II
McQuestria harder.
Remember kids, time travel is possible.

To Touch The Stars
Don't send humans into space. It's bad enough they live on one planet.
As the British Captain of this fine vessel commands you: Stop dilly dallying and get to work!
This work is not to be confused with: To Touch The Stars

Dragon's Fire
Making alcohol in Equestria is more dangerous than it looks.
Bacardi Breezes are a breeze, Bacardi!

Prancesylvania
Miracles can happen twice.
Good thing ponies never had access to nuclear technology... yet.

Celestia Drunk Texts... If She Could Use A Phone
Always have someone stronger than you to take care of you when you’re drunk.
Unless you're an alicorn, no one can stop you. Don't get drunk.

Who Invented Hooves?!
Booping ponies on the nose might seem like fun, but it's actually quite a dangerous proposition.
No one pony should have all this power.

At Your Service
It's just a quick vignette into the life of an average Gorlian.
Gorlians have it tough, but at least their cleaning service is punctual.

Boredom
Pinkie Pie sits there with not much to do. It's excruciating.
Twilight old Pinkie not to touch the orb. Pinkie touched it.

How To Make A World
It's quite simple really. The Universe will show you how!
In which it is all the ways you SHOULDN'T make a world. Oh well.

Foal Move
Teaching a class can be hard for some people, for David? Downright frightening.
Foals are an amazing tool. If used with care.

Australianisms
It's like a secret language and only Australians can speak it.
And 'roos. Don't forget 'roos.

Mustachio
Don't underestimate the power of moustaches.
Twilight did. She regretted it.

Buddy!
When all else fails, you can always make friends with your friend's friend.
Or can you?

Moop
When Moop stumbles upon a secret government conspiracy, it's only logical that he gets roped in
The moral of the story is not to accidentally stumble into abandoned warehouses.

Celestia and Luna announce their retirement and their plans to turn the throne and power over Equestria to the mane 6. Unfortunately, this is the last straw for Twilight, and she goes off on a rant about why this isn't a good idea.

Twilight decided to read a book. She reads many books, but this one was special. It was a special book that she read. And what it tells her is quite a surprise to exactly no one but her. It's up to Spike, Thorax, and Pinkie to help her through these difficult times.

Of course, if she was better at listening, none of this would have ever happened and I could have saved about 2,000 words.

I honestly hate the kind of stories where all of Twilight's friends die.

A submission for the late F*** This Prompt #13.

When Twilight pays her CHS friends a visit on Hearts and Hooves Day, she expects to learn a bit more about their strange world and it's rituals. She did not expect to find out just how much her friends actually think about her. Sex tag is for raunchy language and mild suggestiveness.

Despite their supposed massive power, Alicorns have done a rather poor job of saving the day. Twilight discovers that there's an actual reason for that.

Featured on EqD 6/6/16!

Twilight Sparkle is dead.
Twilight Sparkle is only slightly inconvenienced by this.

The Great and Powerful Trixie, hungering for revenge (for some reason), decides that the best way to gain absolute power is to become an Alicorn. The best way to become an Alicorn?

Kill one and steal their powers, of course.

Aiden Aigo, former coder for the the Canterlot City Internal Operating System and the Aitselec Corporation, current pointless rebel, wants nothing more than to get revenge on the company that fired her. One day, Aiden finds something that may be able to help her do just that.

Provided she can get her to work.

Applejack asks Sunset if she ever misses an aspect of her home. Specifically, one aspect that can possibly be filled in a big way this side of the portal.
