This story is a sequel to Nigel M Chalmers, Emperor

(15/10/2015) Turned status back to incomplete pending an Epilouge and Alternate Endings chapter as per comment suggestions.

After being banished by Celestia for his misdeeds, the alien Emperor of the Crystal Empire is back... and out for revenge.

Emperor Chalmers is not a happy space man. After being stabbed in the back by Equestria, he was sent to the depths of the Underworld. Kicked out for causing too much trouble for the wardens, Nigel now has the chance to take back his empire and show Celestia just how disappointed he is with her.

This time things will be different. This time he has friends.

This story is a sequel to Mission: Improbable

A few weeks after the Spy returned from his extended stay in Equestria, the Medic found that he needed to have a few of those so-called "ponies" to... study. But with robots still attacking Mann Co., how can he find the time to acquire such a specimen?

By sending a scout ahead, of course.

This story is a sequel to Ponies, Pirates and Peculiar Psychopaths

Chrysalis has been driven out of Canterlot, her invasion defeated. However, an old friend from her time before becoming queen is more than happy to help her succeed with her plans.

Will these two achieve their goals, conquering pony-kind and ruling over them with iron fist and hoof? Or will they be stopped in time, preserving the peace that Equestrian has known for as long as can be remembered? There is more than just dreams of world domination at work, though, this is personal for Chrysalis and her rediscovered assistance.

Hopefully, the line that 'Evil never triumphs' will prove to be correct, or else a drastic change is going to descend upon not just Equestria, but the entire world.

Thanks to Avatar of Madness for the coverart.

It had been about a month since the changeling incident in Canterlot. Everypony is on edge, because stray changelings keep popping up here and there, trying to blend in with the population. Everyone worries that one of their closest friends, or even their family, could not be who they appear to be. But what happens when a pony isn't really that pony...

...but they're not a changeling, either?

Changelings.

To most, they are the creatures that almost took Canterlot, shapeshifters able to feed on the emotions of those around them.
While this is true, it is not all there is to the story.

When the Great War began, an alliance was struck between Princesses Celestia and Luna, of Equestria, and Queen Chrysalis, of the Changelings.
The changelings, natural infiltrators since birth, would become spies for Equestria. In return, they would no longer be hunted, permitted to continue feeding as they had for countless years before their failed invasion, provided they not engage in acts harmful to the equine government or population at large.

Of course, that was simply the beginning. As the war began to escalate, Stable-Tec, the company responsible for the life-saving Stables, recieved a request from parties that would, as part of the contract, remain anonymous and unnamed.
They were asked to create something new, something that would allow both changelings and ponies to survive, and promote harmony between the races.

They were asked to create...

Project HIVE

They say revenge is a dish best served cold. I used to wonder, how cold should it be? Well, I know now. The sort of cold that comes from eternal night and being locked in stone for over a thousand years. The sort that comes from the only person you think you can trust betraying you.

The sort of cold that comes from a knife in the back.

The Moon betrayed me. The Sun entombed me alive. And they were going to pay.

For the League of Humans Acting Villainous

In order to improve their skills at detecting changeling infiltrators, Twilight Sparkle and the Council of Friendship ask their new friend Thorax to help them with a little training exercise. Their goal? Figure out which of their six friends is actually Thorax in disguise.

Dialogue heavy, as this story focuses on the cross-interrogation of the game itself.

Note: This story takes place before "To Where and Back Again."

HIE, a Displaced story.
I dont get it. I didn't even wanna go to that stupid convention. I suck around big crowds. Didn't help, what with all the talk of people dressing up in cosplay going missing. I pick up an Escafil cube off some random table to take a look at it, and now I'm stuck in a world of vibrant pony-people?

Holy rusted metal, Batman! Featured on 4/24/15! And again on 8/5/15!...and... again? on 8/6/15?
Thank you guys so much!~

Parents tell their foals that they can be anything that they want.
For me, however, it's a bit more literal.
At least it would be if my parents had said that.
Or if I knew them at all!
So what do you do when you can become anypony?
You become a spy, of course.

BEWARE: SPOILERS IN THE COMMENTS

One conversation can change anything. Your life, your world, your species

It was the beginning of season two when he changed me into what I am now.

Into an emotion eating monster with holes in my hooves and fangs in my mouth.

Follow me, as I find my place as a changeling in world that doesn't yet know what we are.

This story starts in the season 2 episode 1
It's a little cliche yes, but this is something to write while my life gets sorted out

Will get darker and slightly gorey a few dozen chapters from now so I addeed the tags just in case, might change them later
