Celestia and Luna have declared League of Legends an official sport in Equestria, along with announcing the Legendary League of Ponies Tournament to be held in six months. All across the nation, teams are formed, battles are fought, enemies are made, and it all starts due to this game that appears to be a little different than our world's version.

Note: Knowledge of League of Legends not required to enjoy though it does help

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.

How can this be true? When the sun was later in rising than it should have been, Princess Luna became concerned for her older sister. No pony had seen her since Princess Cadance and Shining Armor's reception had ended late the night before. However when Luna went to urge the moon down hoping to nudge Celestia into completing the cycle, her magic brushed against an aura she had hoped and prayed to never glimpse again.

Had her inability to protect the ponies she cares so deeply for, driven Princess Celestia to do... The unthinkable?

Two worlds, two peoples, two varying ways of life. For Equestria and its people, peace has been a staple of life for generations under the watchful eyes of their alicorn protectors. Resources and necessities for life are abundant, and the few times it has been threatened by external foes have ended in an Equestrian victory.

For mankind however, life is a brutal battle for survival in the war-torn hellscape of nuclear devastation. Violence and survival have been a mainstay for the last three decades, and only recently has a coalition tried to reestablish civilization. But the Earth is dying, and this last bastion of humanity only number around 50,000. For man, doom seems inevitable.

One day, two men accidentally discover something that will change the fates of both worlds forever. One man will discover Equestria and its prosperity, coming into contact with the very best Equestria has to offer. He will be shown kindness, and in turn, he will teach them understanding.

Regardless, the rest of Equestria will come to fear what they do not understand and after a tragedy costs humanity's good will, mankind will be left no choice but to invade in the name of survival. A sad tale, but one that history has repeated on numerous occasions. In the end, it will be up to a handful of individuals on both sides to find a solution and bring an end to the conflict. Will these two worlds come to terms and learn to coexist, or will one species be eradicated by the other?

My name's John. I guess my last name doesn't really matter any more. Life is ironic, isn't it? Life nurtures all kinds of species that can get along, but it also creates the species that kills others. In fact, there are some species, who's sole purpose is the death of everything but itself. I'm talking about diseases, of course. Viruses, bacteria, fungi, and even parasites. All my life, I found these things interesting. I loved studying them, so naturally I grew up to be an epidemiologist. When I wasn't studying diseases or doing other basic functions, I was playing one of my favorite games, Plague Inc. It's a game where you try to wipe out humanity using diseases. Over the years, I've become a master of the game, to the point where it isn't really a challenge anymore.

But, that all changed when the game sucked me into itself, and I wind up in a strange land, with even stranger creatures. But that isn't all. I've somehow gained the ability to create and control every single disease I can think of. Now, I have to survive in this harsh world, knowing that I'm one step away from wiping out the entire planet.

Like I said, life is ironic, right?

[Displaced fic]

To any newcomers reading this fic, I want to point this out. The story may seem confusing in the first five chapters, as I was trying to figure out how I want to write the story. I won't be getting rid of any chapters, but some small points might contradict each other across both of them. These points hopefully won't affect much of the future.

In the year 2036 an asteroid dubbed "Apophis" struck the Earth and contaminated fifty percent of its water and atmosphere with an extraterrestrial pathogen dubbed "The SOL Strain." After two years, sixty percent of all human life was gone! With the world's governments struggling to keep their countries together; all seemed lost.

That is where my story begins.

My name is Chloe Cooper and I'm the only known human to be genetically immune to the SOL Virus. During the pandemic, I volunteered myself for experimentation. In order to keep me safe, I and three other humans were locked away in a vault deep within the Appalachian mountains. There these people, who I soon considered my friends, ran many tests on me and the virus, however after months without contact from above it was time to put the project to rest.

Cryostasis pods dubbed: "Cocoons" had been built in case we failed. 16,000 years later I awoke to sirens, signaling a whole host of problems.

And now? I'm the last of my kind.

Character tags will be updated depending on where the story goes

Handy is not a happy man at the best of times.

He was even less happy to find himself in an alien world that offended the very laws of physics and got injured for his own stubborn refusal to accept the obvious path fate had apparently laid out for him.

For his trouble he is now on a journey, with the long term goal of finding his way back home, only to find himself involved in plots and machinations so far above his head and cares that he quickly becomes a pawn in a game played by powers who care not for his well-being.

Quite like his life back on Earth if you think about it.

Needless to say, Handy does not care for any of it. He is much more preoccupied with the more immediate and pressing mundane concerns of day to day life a human needs to worry about while in Equestria.

Obtaining a new pair of shoes for example.

All this and one almighty hangover, what's the worst that could happen?

Rated teen for harsh language and minor violence

Proofread by JBL, Jude and Usurper

Twilight has been having her study sessions with the Cutie Mark Crusaders for some time, and has been remarkably pleased with their progress. And kind of worried, as they keep getting better and better. She might be a princess now, but TEACHING THE CUTIE MARK CRUSADERS? She'd rather not become their formal mentor. Yet.

A letter is sent out, and Princess Celestia gets a call for help. And, an opportunity is born. After all, why not? After a thousand years, perhaps it is time to do something else, just for a bit. She does have a rather wonderful younger sister who hasn't been ruling a land for a thousand years, and who has been studying how to rule for the past four rather intensely. So, teaching three fillies undercover? Sounds like fun.

And Luna. She's wanted to be as respected as her sister so much that she once went mad over it. But now, she's simply being handed the power that she once coveted for so long and no longer wants. What kind of a world does she live in now that her highest desire has been so casually granted?

With all of this, What Could Possibly Go Wrong?

Arcs:

Escape: When Celestia hears the call, she jumps at the chance to teach again, especially three fillies who might surpass her grandest student. But first she's got to escape her own identity...
Examination: So you want to find out what a filly does? Time to test her silly, so long as you don't taunt the Happy-Fun Filly.
Excitement: So, you've found the Happy-Fun Filly. Great, but the other two need help as well, and Scootaloo has this ~Great!~ idea for how to use her new-found magic...
Encouragement: Cometh the Bubbles, and a whole load of new headaches as they find out just what being a Happy-Fun Filly really means...
Exaltation: Where's Luna been this whole time? She can't be very happy about being left in the lurch holding Equestria. She could really use somepony to talk to.
Exercise: 'Sunbeam' is looking to teach the Happy-Fun Filly more, but first she needs to start taking care of the wagon-tire she keeps around her middle so that certain Unfun-Time Fillies don't interrupt her. And there's this big draft stallion looking for help...
