One minute you have a changeling enter your boutique,
and the next minute you're getting a lecture of how offensive it is to think changelings are bugs.

Maybe Rarity should've thought twice before hitting a changeling with a flyswatter.

~Another fanfic I now regret writing...way to go Atlas~

Mysterious portals to a “First World” are appearing all around Equestria. Even worse, there are unknown creatures coming through! When it’s discovered that these creatures are immune to unicorn spells, Twilight comes up with a bold idea to harness earth pony magic to combat the menace. Applejack must take the first steps on a new path she never expected, which just might be the biggest challenge she’s faced yet.

This is pretty much my first work of fiction, so I greatly appreciate any and all feedback. Let me know what you think!

Might contain some incidental Dungeons & Dragons crossover elements, but not enough to warrant the tag, I think.
Rated Teen for mild violence and language.

Jason's life has grown dull. While some may have thought that the weekly monster attacks might have kept him on his toes, he had grown to learn that as the norm around town. Now, after months of living in Ponyville, he can't shake the feeling that there is a void in his life. He follows his usual routine every day: breakfast, a quick shower, followed by a quick walk to the park to read the newspaper. One morning, he finds two parents playing with their filly in the playground. As he watches, an idea sparks within his mind: why not adopt a pony of his own?

There is only one real rule regarding changeling royalty: there must always be a queen. Twilight Sparkle is about to learn this through personal experience.

Originally written for an X Becomes a Changeling prompt almost three years ago.
Set after season three.

The changeling ruler, Queen Chrysalis, finds herself a red ball one day. She decides to have a little fun, but what's fun without someone else?

Comments, criticism, and baking recipes are appreciated.

Based on an idea from DeathWing118

After caring for and developing feelings for a lost, amnesia ridden stallion who was found stumbling out of the Everfree Forest, Fluttershy discovers that he is not the pony he said he was, or even a pony at all for that matter.

Idol Hooves holds a special place in Equestria. He's probably the only exiled changeling to serve in the Royal Guard, or at least, that's what he expects, as exiles don't really broadcast that fact. However, it's well known that Princess Celestia loves all of her little ponies, and her guards perhaps more so, and that makes it one of the best ways for a changeling to discreetly feed.

But how does a changeling even get there, let alone get exiled in the first place? For that matter, why would it ever go to Canterlot? Set a number of years before the series proper, before Luna’s redemption, Idol details how he was exiled, the ponies he’s met, and the series of misadventures that led him to joining the Royal Guard, and should continue a good ways into the series, as something of an alternate perspective.

Soon, he’ll have to deal with a boisterous new princess to serve and a royal wedding in the works bringing a third to power. Will his old instincts bring this new life crashing down around him? What precipitates Chrysalis’s ill-fated assault on Canterlot? Is it really so wrong for a changeling to enjoy good craftsmanship to an obsessive degree?
