Story version of the post of the same name! Credit for the concept goes entirely to Whiskeylullaby.

It's been a couple years or so ever since the Dimensional Tear Incident of 2018—something that no one would've ever thought of happening. On both worlds, everyone is still getting used to the fact that alien life does indeed exist, some coming to terms faster than others. Cultural exchange is slow but relations only continue to get stronger.

In a show of kindness, the U.S sends a volunteer over to the Equestrian side to help manage their security problems; something that's been plaguing them for quite some time now.

It is quite the shame that MA Brandt is in for quite the shock.

The Sapien Wars 27 AE - 32 AE

The Sapien Wars rose twenty-seven years after the founding of the Kingdom of Equestia and ended five years later with the Treaty of Canterlot.

For historians, it sounds like Tartarus.

For the soldiers, it was Tartarus.

Gore Tag is for detail battles, not a lot about gory details.
Teen Tag for Language.

When a mysterious stallion appears out of a portal, Twilight Sparkle is ecstatic. Who knows what other-worldly knowledge this stranger could possess?

Unfortunately for her, that knowledge may prove somewhat limited as this stallion... has a bit of an unexpected handicap.

This is a story all about how a guy got drunk, fell under a horse statue and then turned into a unicorn because he was fed up with the tribalism and hypocrisy the majority of the human race was guilty of.

Unfortunately for him, Equestrian society wasn’t that much of an improvement. So he did the most rational thing and became an evil overlord. A competent evil overlord, I should add.

A competent one that is also OP as shit.

One thousand years ago, Nightmare Moon overpowered Celestia and banished her to the sun. As dictator of Equestria she's come to a slow eventual conclusion. She needs someone in charge of relations. And, like any good dictator would do with a undesirable job, she outsourced it.

An evil force has awakened in Equestria and in an attempt to outwit said force, Princess Celestia summons a being from another world. Plucking them from their own and transforming them into a pony. This poor soul has unwittingly become the linchpin in Celestia's convoluted plot to defeat evil.

The soul's name is Carl and he has absolutely no interest in becoming a hero for some pony princess he only just met. He is rude, foul-mouthed, bad-tempered, sarcastic and overall... a total jerk. How a pony like him is supposed to save Equestria is anyone's guess...
