Shining Armor awakens one night to find a baby pony/changeling on his doorstep. A baby that is apparently his as well as Chrysalis's. Can he keep Cadance in the dark? Can Twilight help him? Is the queen changeling herself going to make an appearance? How many OCs will there be? Will everypony be in character? Who will cameo? And most importantly, was he technically cheating?

Read and find out.

Sequels contain spoilers. As in you will spoil the twist if you even look at the sequel.

I see you scrolling down. Stop that.

Editors: All of you!
Oh and SmilingKittens

An A.I. awakens aboard the HKS Dancer, a desolate and quiet ship. The crew of which is nowhere to be found. And in the wake of all of this the A.I. discovers something.... something peculiar.

A super cool 3d model that is relevant to this story.

In the wake of the events of "Infernal Machines" and the Nightmare's most pathetic assault on Ponyville yet, Applejack is thrown into an existential crisis, despite her not knowing what the word "existential" means. So when a stranger named Stranger arrives in town, teaching a new way of coupling talent to power using complex machinery, she is quickly suckered in, along with everypony else. Now, it falls to the Most Dependable of Ponies to bring the resulting ruckus down to earth, but can even Applejack's legendary pragmatism stand up to the brain-fizzing horror that is... CONTRAPTIONOLOGY?

Now with a Spanish translation by Spaniard Kiwi!

Jessica finds herself flung into a world she has little concept of. Everything is strange and new to her, but worst of all she cannot communicate with the native inhabitants. A world of monsters and sapient ponies, griffons and other assorted beasts is no place for a human girl.

How will Jessica cope? Without an understanding of their language how will she make her way in the world, will she even be able to ever communicate with them? Why was she even brought into the world and is there even a way for her to get home?

(Thanks to Tulip for the Cover image!)

(Also now apparently has a Tv Tropes page in the making. )

Now has a re-telling in progress focusing on the Equestrians' side of things, A Stranger Among the Voices

No one alive today can say where she came from; simply that she has always been there.

And yet, few ponies have had a greater impact on Princess Celestia's life than Raven, her most faithful aide.

Inspired by and based off of a headcanon put forth by Heir-of-Rick, though perhaps a bit less insidious than what he had in mind. He very kindly provided an alternate version of his image for me to use as my cover image! Text added by me.

All comments and criticism very welcome!

Featured in the Royal Canterlot Library! Go there to read the interview for some behind-the-scenes info on this story!

Translations: Chinese, Spanish!

Twilight Sparkle never seemed to notice Lyra Heartstrings. She didn't even remember Lyra's name.

They were friends back in Canterlot and even went to school together. Yet Twilight didn't notice that Lyra just happened to move to Ponyville the same day she did. She didn't even notice when Lyra appeared at her welcoming party. Nor did she ever seem to spot her old classmate passing by in the background on any other day during her stay in Ponyville. Some days she could look right at Lyra and never realize that they knew each other.

Lyra isn't a very noticeable pony. She has put a lot of effort into that.

Set in late season 5, after Amending Fences.
Note: Lots of spoilers in the comments.

Octavia has hit rock bottom. After the Gala and being forced to play that song, she was cast out by high society. Now she must gather the shreds of her pride, only to have to swallow them to work under the only pony that seems willing to hire her. Now it's time for her to make a name for herself all over again, and she's determined to make it no matter what, even if she has to start over from Scratch.

Follow Speaker and his changeling brothers and sisters who, after the events of Canterlot, took it upon themselves to find a new queen. They found a portal in a deep cave and went through it, questionable circumstances aside. Now they find themselves in a world full of humans, and with a new queen!

Meet Catherine and her family as they cope with a gaggle of shape-shifting creatures who really do just want to fit in and be loved.

The problem is, Catherine's parents are not very keen on their daughter chosen to be the new Queen of the Changelings.

And the cat has gone missing.

The story that inspired the two short stories that lead up to this one!

FimFic Authors are In Your Bed by Admiral Biscuit

Which two stories, you ask?

Link to Estee's short story is here.

Link to my short story is here.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
