The Hakurei Shrine has disappeared. A strange thicket has taken its place, filled with an unnatural magic that is spreading rapidly and bent on disrupting the stability of Gensokyo. With the shrine maiden nowhere to be seen, it's up to ordinary magician Marisa Kirisame to bring back the shrine and its caretaker before it's too late.

Meanwhile in the town of Ponyville, a mysterious shrine has appeared in the Everfree Forest, fiercely protected by an equally mysterious mare. With the rest of Ponyville still shaken by the latest disaster, it's up to aspiring musician Lyra Heartstrings to discover the truth about the shrine and the mysteries within.

It's all fun and games during magic practice until somepony sneezes during a teleportation spell and sends you Celestia-knows-where, isn't it? Next thing you know, you're in a land of bizarre creatures you've never seen before, and even after one tries to eat you, you have to befriend them to find a way home. Don't you just hate it when that happens?

(Now with a Tvtropes Page!🥳)

Her Majesty Princess Celestia, the Prideful self-styled Goddess of the Sun and mother of all sins who crossed the thin line between righteousness and self-righteousness.

You are the ruler who hides her hunger for power behind lies and facetious benevolence while condemning an entire race to extinction.

We have decided to make you confess all your crimes with your own mouth.

We will take your distorted desires without fail.

From,

The Phantom Thieves of Hearts.

When a huge chunk of Equestria appeared floating above Japan surrounded by a bright golden barrier, everybody panicked until Celestia appeared before them with promises of friendship and peace…

But then things changed.

The Barrier soon started growing, engulfing everything on its path and killing every human it touched while leaving behind everything else, albeit “Purified”.

Even Celestia changed, and what once were promises of camaraderie and brotherhood, became veiled threats:

“The Barrier cannot be stopped, we are sorry.”

“We cannot control it, but you can still be saved! Convert! Become a pony! Become one of us and the Barrier and the Magic of Equestria will no longer hurt you!”

But while some believed the words of this gentle mare, others felt mistrust and fought back, turning the offer of Conversion into an obligation:

Convert or Die.

All while still begging Humans to accept, even when Conversion showed dire downsides to the humans undergoing it.

But there is no longer time, if the humans can’t decide, the Ponies will decide for them: Conversion! Conversion at all cost!

And from the shadows of despair, a last spark of hope emerged!

A group of young forgotten heroes, called back in action by the Staff of the Velvet Room to enact the Greatest theft in history!

It’s time for the Phantom Thieves to return, and steal the purest hearts of them all before those too fall into Distortion!

This story is a sequel to He Come to Town

Brave Heart, former agent of SMILE, has found new purpose as the captain of the Twilit Guard.

He is also the only member of the Twilit Guard.

The only thing worse than that problem will be the solution.

Set during late Season 5. Cover image by ImAFutureGuitarHero, used with permission. No familiarity is needed with the prequel beyond the fact that Pony Link is working as a guard for Princess Twilight.

A few months after Twilight's transformation and coronation, Fluttershy finds herself in a new world, transformed into a human girl and comes across a boy named Kenji who lives in this strange new world. However, she soon discovers this new dimension is much more hostile than it seems. For in this world, humanity fights to stay alive against the Kaiju, a race of gigantic beasts capable of wiping entire cities off the face of the Earth. Even worse, as Fluttershy tries to find a way back home, her presence attracts the attention of the more malevolent Kaiju. Rated Teen for violence, mainly concerning traditional giant monster violence.

While on a quest for the mythical Armor of Invincibility, the two of them end up transported to Equestria.

You'd be an absolute fool to miss out on such a party...

The girls of Canterlot High come up with a rather unconventional plan to save Camp Everfree.

It is a plan that requires them to take off their clothes.

Now with a Spanish translation by Spaniard Kiwi!

As the former Bearers of Harmony and future Council of Friendship prepare to take the reins of the nation, something has to give. In this case, "something" is their positions at the School of Friendship.

This leaves said school's new headmare in a bit of a predicament. After all, the school now has two headponies, one counselor, and zero teachers.

At least qualifications were never a big concern.

Rated Teen for more risqué innuendo than the show could get away with.
