[Second person fiction between you and Luna]This story is a more realistic take on a pony X royal sister fiction in the sense of how it would actually happen. After a spell cast by Princess Celestia goes awry.....you, a simple brony, have been sent directly to Equestria. No, no instant cutie marks or instant shipping is in this fiction. Trust me, I know what I'm doing. However, if you don't like human in Equestria stories OR steamy scenes, then stay away from this fiction. Simple as that.

This is pretty much a self-insert, mostly done for comedic purposes.
After a mishap with an invention of mine, a friend and I find ourselves in the magical land of Equestria. How will the peaceful land of Equestria handle the influx of two humans? Will Jay and I ever find a way back home? Will anyone give this story a fair shot? Read and find out.
Things that actually involve MLP:FiM begin in the second chapter.

The sequel to Wayward Courier. Read that first, or you'll get lost.

Two months after his first visit to Equestria, Thomas has returned. And this time, he's not alone!
Now the ponies have to deal with not only him, but a depressed snarky ex-Scribe and a Brotherhood Ghoul with her own list of incredible achievements and emotional baggage.
However, things aren't well in Equestria, as they quickly find out...

All major details relating to Season 3 are non-canon to this fic.

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.

The supernatural: Ghosts, zombies, werewolves, spirits... vampires...

Twilight Sparkle always thought that the supernatural was just a bunch of superstitious nonsense, just some scary stories to tell around a campfire. She couldn't have been more wrong.

After an occult ritual gone horribly right, Twilight finds herself among the ranks of these so called 'myths', whether she likes it or not. Due to the same force that changed her, dark shadows have begun to spread across Equestria, bringing to life these ancient fairy tales. And Twilight might just be the only one that can stop them...

For better or for worse, Twilight has been changed. Will she embrace this dark gift and become the hero Equestria needs, or will she eventually succumb to temptation and become the very thing she fights?

While pursuing a splinter of Hive Fleet Behemoth, Captain Sicarius and the Ultramarines 2nd company are caught in a warp storm that carries them and their prey to an unknown planet. Meanwhile, Princess Luna notices something strange in space that could spell danger for all of Equestria. Swept up in a war between the terrifying Tyranid swarm and the vengeful Ultramarines, the ponies must fight for their lives in a war that spans a galaxy.

After a mishap involving the Transportalponder, the Courier finds himself in a place he doesn't recognize. With no way back and nothing else to do, he decides that wandering into the nearest town is the best option. Being the Courier, things aren't that simple...

A Fallout: New Vegas/My Little Pony: Friendship is Magic crossover

The style alternates between omnipresent third-person and the Courier recounting his tale to... Well, take a guess.

Diablo Crossover.

The Archangel of Justice destroyed the Worldstone to spare Humanity the corruption Baal infected it with. The force of its death knell shatters Mount Arreat and sends Tyrael hurtling across the endless planes of reality. He falls upon a world untouched by Angel or Demon, far from the sight of the High Heavens. So far, in fact, that he fears he will not be reborn from the Crystal Arch.

Wounded and near death, hope appears in the form of two strange creatures bearing the power of night and day.

Tyrael now faces a time of recovery as his power slowly heals within a body fashioned for him by his saviours. Justice Incarnate tastes for the first time the life of a mortal, and it is a strange, confusing experience .He has been left in the care of one Twilight Sparkle to learn of this world.

After all, where better to find peace and harmony than Ponyville?
