Twilight had planned to visit Sunset Shimmer and her friends over in the other world for a nice, quiet weekend, away from all the worries and problems associated with being a Princess of Equestria. Unfortunately, things rarely go as planned.

After an accident cuts her off from Equestria, Twilight finds herself stuck in the human world until the gateway between the two worlds can be fixed. Which wouldn't normally be a problem...

...If she wasn't still a pony.

Proofread by Dusty Old Qrow, RQK, Dusty Tomes (Ch. 2), Emtu, and Doctor Candor.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

This story is a sequel to Guardian

(This story is a Novella taking place in the Guardian story universe. This story continues with the sequel Legion.)

Tempest Shadow had heard the rumors. Stories, told in frightened whispers by traders and wanderers, in the taverns and around campfires. The stories told of an almighty champion, a monstrous creature from far beyond the stars, that had come to defend Equestria from its enemies. The stories told it had slain dragons by the hundreds, broke the savage beasts of the Everfree like twigs beneath its boots, and torn down titans and monsters alike with its wrath. They said it wielded weapons that could turn mountains into gravel, and seas into desert. That it was clad in armor, that neither the sharpest blades, nor the mightiest magics, could pierce. The rumors said it was unstoppable, relentless, beyond the power of mare or beast to oppose, that it was. . . a god. Tempest had laughed at the rumors and stories, as she flew toward Equestria at the head of an armada, intent on the conquest of her weakling former homeland. Never once did she give the obviously absurd campfire tales even the slightest credence.

This story is a sequel to Little Lost Pikachu

It has been over a month since an adorable Raichu named Nica crash-landed in a strange world called Equestria, and nearly a week since Astra and Ash’s pokemon followed, along with her charming brother Ace. After a few dangerous and thrilling adventures, and one or two snuggles, Twilight was able to find a way home and create a portal back to Alola.

Now, backed by Twilight, Starlight and Rainbow Dash, the pokemon begin their quest to reunite with their trainers and introduce the ponies to their world. Though, rather than come home to a lively vacation spot filled with humans and pokemon alike, they encounter a dangerous challenge, one they might not be able to defeat.

Will Twilight’s team and the Chu brigade be able to overcome the odds and defeat the foe that brought ruin to Alola? Or will they share the island’s fate?

Long ago, the Seraphim granted power to the Doom Slayer that he might conquer the forces of Hell. The Doom Slayer has won, Hell lies defeated, and now he returns to the Seraphim's holy realm. His mission is not over though, he has promises to fulfill, rewards to collect, and as always, evil to defeat. Let those who would harm this sacred land tremble, for the Guardian of Equestria, has returned!

(This story now has two sequels: Legion and the novella Doom Slayer.)

Inspired by the heroics of the mysterious mare known as the Stable Dweller, Silver Storm, a guard of the town of Marefort, decides to go on a daring mission to rescue her captured brother. Of course things rarely go as planned and her attempts at heroism drags her into a tangled web of plots and conspiracies as warring factions vie for control over the last great city: Dise.

The human, Honored Service, returns to Canterlot after being thought dead for a year. This is the story of what happened to the unlucky human in that long year away from home.

First story found here. Click it.

The lands of Equestria aren't as safe as they once were.

What was once a gently trek across fields of beauty and wonder have changed to battles with spirits and death. Most ponies can't go a few miles without having to battle for their souls against ghosts and spirits, all who wish to drag them to the dead.

And to top it all off there's a creature that haunts a mountain at the edge of Equestria, a creature that no pony has ever fully seen. Fast as a blur and cold as the grave, none know who or what it is.

All we do know is that whenever it appears, it brings disaster with it.

This story is a bit of an experiment for me, so if things seems weird or don't add up all the time, that is why.

Twilight Sparkle has come across the impossible. A book she's never read before, with an odd plus-like shape emblazoned on the cover. What is this book, and what does it mean for Equestria?

Meanwhile, Isaac has been stuck in the basement for a long time - centuries? Millenia? But when he finally finds a way out, will he be able to adapt to the planet that's moved on without him?

Crossover with 'the Binding of Isaac : Rebirth', a game by Edmund McMillen.

Rated Teen, because somebody can't keep it polite.

This story is a sequel to The Crown of Night

Now available in print from Lulu.com! Hardcover - Paperback.

(New readers, unsure where to start? The Education of Clover the Clever is best.)

Clover Cordelia is a freshmare student at the Cambridle Academy of Magic who is determined to become a great sorceress.

Star Swirl the Bearded is a legendary wizard in need of an apprentice.

It's a tough job, working for the world's greatest wizard. On top of the usual challenges of student life there are apocalypses to deal with, and assassins who show up at inconvenient times, and plant life scheming for world conquest.

It's probably nothing Star Swirl can't take care of, provided he and Clover manage to resist killing each other first.

Previously updated alongside its prequel, The Crown of Night. It is not necessary to read The Crown of Night first.

"Characterization is the name of the game here, and this story's take on Star Swirl is one of the most enigmatic and intriguing I've seen. His eccentricity is offset perfectly by his straight mare, Clover the Clever, and the interactions between them are a joy to behold."
-Prak, PR for the Royal Guard.

"Ok, so I like this story. I actually like it quite a bit. I have no clue why though. Not a single clue.
I haven't a clue what you're doing right, but keep doing it. You're awesome."
