The Castle of the Two Sisters has a long history, dating back to Equestria's early beginnings. Back when Star Swirl still taught the ponies who would become the future rulers of Equestria.

In the present day, Star Swirl's research into dimensional theory has created connections between two worlds, and even helped facilitate cross-dimensional friendships.

But not all of his experiments were recovered or even recorded. And not all of them were considered dangerous enough to be destroyed.

[Human-kitsune transformation]

Ethan McIntyre was a young man with aspirations to become an actor, stage magician, and/or special effects artist. So who else should he go to a convention as, but the special effects based supervillain, Mysterio! (The Animated One, because comic books ruined him like they did everything else!)
How could a purchase from a mysterious merchant lead to him being transported into a world of magic in which the inhabitants believe him to be a powerful sorcerer with villainous intentions?
Can Ethan pull of the part of a lifetime and fool the world into believing his abilities are not all just the super-tech versions of smoke and mirrors? Or will he fall before he finds the reason why he was displaced into such a strange turn of events? And will he stick to the moral compass he always followed, or lose his way to the temptation that comes from his new found role?

I don’t know if I’ve truly died or lost my mind. What is reality, what is sanity? Are they not just a product of society, a unit to be measured? Something that can be judged, evaluated, and constricted by belief, but also something that is limited by our very biology? I’m not really sure, yet I believe myself to be sane, and have decided to embrace my own reality. One born purely from thought, bound by the limitations of my imagination. This… is a tale of ”my” reality, my triumphs, my mistakes, and the sins of a father.

Wastelands. Dystopias. Playgrounds for megalomaniacal villains. Each time Starlight forced her into a new world, it was just another variation of Tartarus that she was glad to leave behind and forget about. Unfortunately, thanks to over thirty timeline jumps, Starswirl's spell has gotten worn and frayed, forcing her to stop in this latest world to repair it. Fortunately, things seem relatively peaceful. Unfortunately, Twilight soon finds out the reason for that peace is...complicated.

This story is a sequel to How to Hug a Five-Hundred-Foot Tall Dragon

It was supposed to be a routine flight over the desert, just a relaxing trip to stretch his wings out. He'd done it a thousand times before.

This time, it wasn't so routine.

Sex tag is for innuendo. No clop.

Part of the Hellpiercer 'verse, but knowledge of that story is not required. Reading the direct prequel How to Hug a Five-Hundred-Foot Tall Dragon is advisable, however.

A United States Air Force AC-130 is transported to Equestria while in transit through the Bermuda Triangle. Insanity aside, this motley crew of aviators must juggle their duties while treading the uncertain waters of diplomacy.

Disclaimer: I've decided to write this in an attempt to get a more realistic view of what military in Equestria would act like, rather then the dark brooding kill happy stuff I've read. So with that being said, these guys will act more like diplomats. So there won't be much gore, and they certainly won't be going on a killing spree. (Obviously, as fiction the term realistic is applied loosely. My main goal is a realistic characterization of one specific community within the military. Just keep an open mind about how sub-cultures can exist within an entity as large as the U.S. military and you'll be fine.) Also rated teen for obvious reasons, morbid humor, light swearing, and background stories.

Maggie Wilson (26), on a smoke break from her dead end convenience store job in the California mountains, encounters the divine god-princess of a dead world. The princess asks for her help. Mag says yes.

So how do you resurrect a dead world?

Not every wishing star is real, nor do those that are have any real power, but when three friends wish on one that meets both criteria, they end up in Equestria, missing more than a few years of maturity. Tossed into a new life because of a blotched attempt at wish granting, coping is going to be the first challenge they face in a world that isn't quite what they expected.

When Equestria accidentally opened a portal to another world, they discovered a new species: humans. Their arrival changed the world. For the Equestrian Ponies, it heralded a great cultural and technological jump needed from their stagnating way of life. For the Gryphons, however, they represented something baser: an opportunity to increase food stock and finally have a 'friendlier' predator species to ally themselves with.

For Gilda, one of the the humans was Ancestor-sent, a soul she would protect for bringing much joy to her life. And when a chain of events force her to accompany her human to Equestria, she recalls the circumstances of their meeting, the trials they pass through, the friendship forged through fire, and love born out of understanding under the harsh skies of the Kingdom.

This is her story.

"You are mine!"
