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.

Unhappy that her future as a member of the monarchy is denied by Celestia, Sunset Shimmer escapes through Starswirl's mirror into another world, planning to take it over to prove once and for all she was fit to rule. What she didn't expect—besides a species change—was to arrive in a world already conquered.

Before you read: This is a side-story to XCOM: Ranger.

I will provide all possible information needed for those that do not have the time—or inclination—to read the other story to still be able understand this one. It's a LOT of info, however, and I'm not just going to dump it all in one go. The backstory will emerge as the story progresses.

70 years ago, Equestria was rocked by an arcane cataclysm which warped the bodies, minds, and magic of every equine species in the world. In the modern era, Ponykind is forced to rely more on technology than magic. Mages work to discover how to use their new bodies to cast ancient spells Equestria once replied upon. International politics are weaker than ever. Eldrly ponies lament they are entering their twilight years at a mere 120 years of age.

In this new world, some have gained abilities once rare or even unheard of outside of the pages of comic books. Some of these ponies, inspired by the Elements of Harmony's work last century, chose to use their powers for the good of all. Others, decided to walk down a more selfish path. The conflict between these groups spills out into the streets of nearly every city and town in the world, and has plunged Equestrian into chaos.

With Princess Twilight focusing nearly exclusively on undoing the effects of the Cataclysm, there is little the Crown can do to keep Equestrians safe from themselves. It is the absolute worst possible time for an existential threat to come to Equis... And so, one has. Unbeknownst to all, an Interstellar Empire works in the shadows, priming Equis for invasion.

Fate has chosen one Equestrian archeologist to be Equestria's shot at remaining a free people. Fortunately for all ponykind, their unknown enemy has enemies of its own.

This story is a sequel to Captain Goodking and the Nightmare Knights


NOTE: I can't believe I have to say this but since people are adding this story to their favourites yet forgetting to click the thumbs-up button, resulting in an inaccurate like/dislike ratio, would those who read this story and like it please click the thumbs-up button when you are adding it to your favourites?

It's been two years since the two sisters have retired and Twilight took over their royal duties for them. While there has been much peace and prosperity, as well as most of Equestria's enemies either being permanently defeated or have turned over a new leaf like Captain Goodking, it appears they still have one more threat to deal with. But Twilight and her friends aren't taking on Kronos and his alien army alone. They have a Time-Turner on their side! Oh, and Captain Goodking as well but he won't be useful until later on.

Special thanks to DmitriTheWriter for editing this story and for giving me the idea of the Seals of the Planets and Kronos (actually considering making him co-writer). And why yes, that is Korriban (or Moraband, as some people in the galaxy like to call it) that some but not all of our characters are on. If you don't think the possibility of our heroes facing Sith Lords is awesome enough, I also got ADVENT!

Inspired by "The X-COM Files" mod.
It's late 1996 and "The Extranatural Commission" is just an international supernatural investigation agency. They were created to combat the weird, but there's not much two field agents with Glocks can do.
This missing persons case started just like the previous two, but the outcome was nothing like they expected...

"Other" will include Spike, Snips, Snails, Luna, probably Coco Pommel, Starlight, Trixie, Celestia, changelings.

The cover uses pony vectors by AleximusPrime and the image the game picked for Kamran.

The introductory arc (former chapter 1) is snowballing and will take 1-2 weeks more. I'll try to update 2-3 times a week. Hoping to start real mayhem in March.
