This story is undergoing a massive rewrite. Expect everything to change soon.

A Russian MVD Spetsnaz team is sent smashing into the ground after the Mil Mi-24 they were in was knocked out of the air. A short time later, the crew and passengers wake up to find themselves in the wreck of the helicopter - but nowhere near Moscow.

As they desperately attempt to find out where they are, they will discover that they are not alone: Other humans have also found themselves in similar situations. However, these disorganized forces may soon be fighting for their survival, against an enemy that they could never have planned for...

The original version of the story, as published 2013-2015, can be found here for those that want to read it as it was. Editing on the original story was done by The Rainbow Brony, and I am thankful for the time that he put into the story to make it better than it would have been otherwise.

A human wakes up to find that not only has he been altered in species and gender, but that he has also landed halfway across the world from Equestria, in an unfamiliar land.

This is not that story. Not yet, anyway.

A decade in passing and Kaz has gained a reputation as a member of a well-known group of explorers traveling the world. Not once have they set foot on Equestrian soil, and she was content to keep it that way, for her appearance would bring about unwanted attention from a few certain ponies and one certain baby dragon. So what happens when the rest of the group hears of unbelievable tales of Equestria, and decide that it's time they paid a visit?

An impending disaster, that's what.

Luna and Twilight are sunk into a fractured, feudal world, where the knowledge of magic is lost. Penniless and depleted, they're forced into playing by other ponies' rules, all the while trying to discover even where home is.

10 Years before the Battle of Reach, the Human-Covenant War rages out of control, with neither side gaining the upper hand. When a damaged Covenant Carrier, crash lands on Equestria, Ponykind finds itself drawn into the war when the Covenant attack, forcing them into an uneasy alliance with the Covenant's sworn enemy: Humanity

A close encounter with a category three Kaiju leaves Midsummer Night, a Mark-II Jaeger, in the inky depths of an unknown ocean. With no communications or navigation available, the pilots, Shane and Michael O'Connell, are well and truly out of their element.

Good thing they accidentally brought something with them to liven up the party,

Ambushed. Defeated. Broken. Banished from his world, he expected his story to end, his revenge unfulfilled. Instead, he found himself in a new world - a world of peace, tranquility, and harmony.

May God help them.

NOTE: Before you read any further, please check out this blog post (or the last few paragraphs anyway) explaining why this story is getting re-submitted despite being... what it is.
With that said... enjoy, I guess?

Heya, welcome to ‘Revenge is Bittersweet’! I’ll try to summarize the most important things for you here.
But before we get started, let’s have some disclaimers:

WARNING! THIS STORY CONTAINS:
-PONIES (who knew?)
-A DARK/TRAGIC SETTING AND PLOT
-STRONG (yet mostly ponified) LANGUAGE
-PORTRAYAL OF VIOLENCE/GORE
IF YOU ARE OFFENDED BY THOSE THINGS, YOU SHOULDN’T READ THE STORY!
BUT PLEASE CONSIDER THAT YOU’LL MISS SOMETHING IF YOU DON’T!

So, now that we have cleared this issue, let’s have a general overlook of what will await you:
As you may have already read, it’s a story about a stallion (my pony-OC to be exact) straying through Equestria and seeking for the abductors of his daughter; first person narration.
I guess it’s needless to say that his journey will include meeting (and interacting with) most of the main cast and the Princesses; the storyline will describe how he turns from a loving and peaceable father into a violent, vindictive killer. I guess the word ‘Tragedy’ quite much fits the bill.

Something about the setting:
-The universe the story’s set in is a rather dark one: Equestria is ravaged by a war/conflict between Celestia and Luna; the details of it will be explained in the first chapter.
-The Rainbow Factory (borrowed and slightly adapted from AuroraDawn’s eponymous story) will be featured.
-A few years have passed since the events of the series; the main cast is a little older, the CMC are almost adults.
-The ages of the characters are stated in human years for convenience.

A ‘Teen’-rating is appropriate at the moment, but the rating can (and probably will) change towards the end of the story.

The amazing cover art was drawn by Pandramodo. If you don’t know about him yet, you should definitely get to know him! So don’t hesitate, go ahead and check out his gallery!

The swords the soldiers of the Republic/Empire use were inspired by those in this epic PMV by BronyDanceParty.

And (just in case this isn't obvious) if you like the story, feel free to give it a like, a comment or a fav! Every kind of feedback is highly appreciated!

So, I guess that’s everything! Thanks for reading everything so far! I hope you’ll enjoy the story!

And don’t forget:
-The story itself and the OCs [Fippo; Firespark; Emberstripe; Halo Star; Poppyshine and Stormtrotter] are by me.
-The credit for the original idea of the Rainbow Factory (and the flight test) goes to AuroraDawn and WoodenToaster, respectively. I don’t claim to have created it, since I borrowed the factory and the general procedure from ‘Rainbow Factory’ and only altered it slightly.
-All other rights belong to their respective owners.

"We live in what we believe is a shell, a closed sphere where all is constant. As physics would have it, nothing in the universe is unique, nothing is wasted or destroyed: it is repurposed. But now I prove them wrong. With a single idea, I realize that we are not so insignificant as we think. We are not slaves to destiny and existence. We are the ashes of gods, the fruits of eternity, the products of choice and fate. We are not meaningless. This universe is not our prison.

This is our empire."

"I was too late again. Nothing ever comes easily for me, does it?"

A Night Fury dragon who believes she is worthless and dangerous, is offered her heart's desire. Seizing the opportunity, she finds herself in the magical land of Equestria. But one cannot flee from one's conscience, and past mistakes weigh heavily.

And it would appear that dragons are no more welcome in Equestria than at home.

Special thanks to Enderstorm for the amazing artwork.

In worlds ravaged, be it by war, natural disasters or extraterrestrial causes and left with no discernible future, there is always those insane enough to differentiate themselves from the shattered populace of their kind, often taking up arms against the unknown.

Kazimir Omelchuk, one of the most experienced Sparta Order stalkers in D6, is one of them.
Rita Vratsaki, a veteran Ranger whose history makes her one of the scarred survivors of the Mojave, is also one.

When these two are transported to a wasteland that only offers more nightmarish dangers and maddening sights, they will find that the fight for home and the future of three worlds, with the aid of unintentional and unexpected allies, has begun.
