Tanya Degurechaff gets tossed into Equestria and transformed into a Changeling Queen. It's a nice retirement from modern warfare as an aerial mage. Then Queen Chrysalis attacks and forces her out of retirement. Historians refer to this as 'a bit of an oopsie.'

A young girl, having been robbed of her childhood and very life by illness finds herself given a second chance in a strange world and with an even stranger body. With a new life, family, and even a brother, she tries to cope with the bizarre world she's found herself in while also trying to embrace her role and become worthy of the gift she has been given.
Being a princess can be hard however, even if it's only an honorary title, especially when you're the twin sister of Prince Blueblood.

Warning, very slow burn.

When Princess Twilight Sparkle seeks to modernize Equestria, one of her first targets was the Equestrian rail network. Seemingly overnight, most lines were nationalized, the out of date steam locomotives were abolished and replaced by diesels and electrics, and unwanted lines were being ripped up left and right.

In a time where sentimentality could not stand in the way of progress, two colts will take it into their hooves to save an old line and keep its hundred ton secret safe from the scrappers torch. But they will soon learn that running a preserved railway is much more difficult than simply clearing the weeds and running trains.

With time of the essence and the scrappers torch an ever looming threat, hop aboard for an express run to adventure!

This story has received a complete overhaul, promising better storytelling, better character arcs, and more accurate railway practices!

After attempting to impress the judges during her entrance exam for Celestia's School for Gifted Unicorns, something transpires that alters Twilight's life irrevocably, as well as the destiny of all Equestria. In a very literal manner, Twilight metamorphoses into the embodiment of magic, much akin to how Discord embodies chaos. How will this unprecedented transformation shape forthcoming events? And how will Twilight grapple with mastering the newfound god-like abilities that have been unexpectedly thrust upon her?

The Crystal Empire disappeared long ago during Princess Celestia and Princess Luna's quest to cleanse the land of Equestria from all forms of evil. King Sombra was a great threat to their entire world and when his defeat came about, at the cost of the Crystal Empire vanishing from existence, it brought nothing but a whole lot of good to the world.

What they didn't realise however, was that Sombra had survived their confrontation and was now plotting his revenge against them both in the one way he knew how.

Twilight Sparkle thought she was the luckiest filly in all of Equestria when Princess Celestia asked her to become her personal student, but she had no idea she'd be a pawn in a game nopony is even aware exists.

Warning: This story and this description both contain spoilers for the Web Novel: Worm. If you don't want to be spoiled, read Worm first, then come back and read this

The apocalypse had come at the hand of a god-like multidimensional alien entity. Taylor Hebert, a parahuman with power over bugs and bug-like things has her powers altered by a former enemy and subsequently uses morally questionable means to make everyone in existence with superpowers fight this evil deity, eventually defeating him.

This however came with a cost. Her mind was deteriorating as her power was subsuming her. Thus another cape decided it would be a mercy to put a pair of bullets in the back of her skull.

Another entity witnessed all of this. This entity, grateful for Taylor's role in stopping this alien god and thus saving countless worlds and thus countless lives, decides to intervene. It brings Taylor to Equestria turning her into a Changeling Queen in the process.

(Warning, Dark, Death, and/or Tragedy may be added to the list of tags in the future, depending on how things go. Furthermore, the Suicide tag is for the references to suicide in the description and in the first chapter. Suicide and/or self harm will NOT be a major theme in this story.)

(This is a crossover with the web novel called Worm by the author Wildbow. I highly recommend reading it if you haven't, it's a really good story!)

A Japanese Salaryman finds his life cut short by a disgruntled employee. Just before his death he is given an ultimatum by a certain God of Chaos.

Forced into a new world, he – now she – wishes only to once again climb the corporate ladder and live a comfortable life. Unfortunately, she finds herself born in the radically republican former Griffon Duchy of Cloudbury where every citizen clamors for continent-wide revolution, and rampaging bandits prowl the countryside. Could things get any worse?

ERHEBEN SIE DIE TRIKOLOR ÜBER GRIFFENHEIM! FÜR DIE REPUBLIK! DIE REVOLUTION LEBT!

An Equestria at War x Youjo Senki (Tanya the Evil) crossover. A mix of two Alternate World War Universes. The Salaryman (Tanya Degurechaff) is the only character from Youjo Senki in this story. Any understanding of that franchise is not needed (to the point where this is arguably not a crossover).

I wrote this because my EaW installation is constantly crashing for me recently (worked for 4 years with no issues until now... ) so I am writing this to tide me over until it "magically" fixes itself with a patch or something. That, and there is a horrifying amount of monarchist apologism and startling lack of republican fanaticism in the other EaW fics /s.

Most characters are not my own, but made by Lauren Faust, Carlo Zen, or the EaW writing team. However, the source of the cover art of griffon-ized Tanya Degurechaff is all me.

A soldier, an archeologist, and an android move to a small town in the furthest reaches of Equestria—a town run by a classified institution that safeguards the odd and inexplicable. A town built over the ruins of an ancient pre-Equestrian civilization. A town in the middle of a corruption scandal relating to an ancient artifact of unknown power.

If you ever met Sunstone when he was but a young colt, you would’ve seen a large grin, two purple eyes full of determination, and an earth pony who could take on the world.

But something happened over the years. As Sunstone grew older, more and more did his cheerful smile morph into an ugly scowl. His enthusiastic attitude gradually capsized, leaving in its stead a disgruntled husk of his former self.

Shining Armor and Twilight Sparkle: Two gifted unicorns that would quickly undermine everything Sunstone has been hoping to achieve, unintentionally turning him into the underdog he never wished to be. Resentment overtaking his better judgement, feeling doomed to be living forever in the shadow of his immensely successful brother and sister, Sunstone has had a lifetime of feeling thoroughly unremarkable.

Unable to bear his inability to stand out amongst his younger siblings, Sunstone vowed to never see his family again. It’s been five years since he departed on a journey to finally understand his true place in Equestria.

Not once has he looked back at the life he left behind.

The age of chaos has come to an end. The Avatar of Chaos, Discord, has been defeated by the valiant actions of the newly-minted alicorn sisters. Their courageous victory has earned them the adoration of their hometown of Evergreen, and they now seek to unite all of ponykind under their banner.

In the disconnected world left in the wake of Discord's reign however, theirs is not the only story to be told. Not all of them even start in their world, for that matter.

Geralt is a unassuming man living a comfortable but mundane existence. While not dissatisfied with his own life, he has always dreamed of what it would be like to make more of himself. To be able to live a life of adventure and glory, to steer the wheels of history.

Fate has smiled upon on him and granted him the opportunity to do so when he is swept away by a chaotic winter storm across worlds, finding himself in a new feathery body. He soon finds himself taking the first steps and rising above anywhere he thought he could reach as he defends his new home, and begins to build a shining beacon of prosperity that will resound throughout the ages.

But victory comes only to the prepared, and the road to his dreams will be long and hard. It is world filled with all manner of mysteries, monsters, and rivalries. A world where a land is kept safe by the armies that it fields. And so Geralt will resolve to stand tall, to defend his lands and his people, and to see his banner flying forevermore.
