On a dark day, one may wonder: just what horrors lie beyond the veil of the heavens? What ghastly demons exist that could only spawn in a pony's dreams? What terror!? What blight in the face of all that is good!? What- wait, it's the Mane Six?

What sort of twisted reality contains a lycan Applejack, a vampiric Fluttershy, a ghostly Rarity, and a lich queen Twilight Sparkle, you may ask? Why, it's just the Nightmare Realm, existing one and a half dimensions below and above the normal Equestria, and they are sick and tired of Nightmare Night not living up to its name in the 'real' world.

However, are these nightmares truly nightmares, or do they just like a good scare? Why, it depends on who you're talking to! So sit tight, give way to fright, for coming soon is Nightmare Night!

Pinkie Pie invites her friends over with the promise of one of the greatest meals of all time. When they get there, however, it is revealed that Pinkie is not the one that is cooking, but rather two tall creatures who occasionally squawk like birds.
And they're about to permanently change the friendship game.
Wachu know about love and tolerance, hater?

As Twilight Sparkle awoke one morning from uneasy dreams, she found she had been turned into a changeling.

How has she become a changeling? How will she adapt? How will her friends respond? And what new terrors will her metamorphosis bring?

Thanks for everything guys. I never expected this thing to get so popular. I need to rework the second chapter, but it looks like there's going to be a blue moon every Friday for a while yet. Thanks again for your support and please keep reading and reviewing!

EDIT2: I've updated the character list again, a little preview of the second story arc...

EDIT 3: Just doing a quick character update to account for changes made to the next Arc...

There really is no excuse for forgetting something as important as a hoof-written law. But Celestia forgot. And now, a thousand years after she wrote it, a law comes into play mandating that Celestia take a two-month sabbatical from her duties as Princess of Equestria.

So what happens when she has to step down for a couple months and leave Luna by herself in the bloody gladiator ring that is Equestrian politics? What happens when Celestia has to disguise herself and mingle with the populace of Ponyville without them knowing?

The short answer to that would be "a string of hilarious chance encounters, sisterly banter, romantic mishaps, and a political coup that was decades in the making."

The long answer, of course, is this story.

[Second person fiction between you and Luna]This story is a more realistic take on a pony X royal sister fiction in the sense of how it would actually happen. After a spell cast by Princess Celestia goes awry.....you, a simple brony, have been sent directly to Equestria. No, no instant cutie marks or instant shipping is in this fiction. Trust me, I know what I'm doing. However, if you don't like human in Equestria stories OR steamy scenes, then stay away from this fiction. Simple as that.

Queen Chrysalis and King Metamorphosis are two ruling changelings from two separate Hives, each one having a certain enmity toward one another due to events in their past. When they separately learn of the wedding between Princess Cadance and Shining Armor, they plan to ruin it by taking the places of the ponies to be wed. However, they are completely unaware of each other's involvement or intent.

With both putting on a deceptive act toward one another, what happens when the deceivers are unknowingly deceived themselves? And can Shining and Cadance, each believing they must save one another from a fake, be reunited, or will they fall prey to the entrapment of the changelings?

An alternate storyline to A Canterlot Wedding.

Dedicated to Victor Frost, for without his Colt Version of "This Day Aria", I might never have come up with this.

Princess Luna's Lunar Stallions kidnap Twilight Sparkle when they see how lonely Luna is, and give her to the Princess as a gift. Nightmare Moon emerges from Princess Luna's psyche during the sleepover. The dark goddess would love nothing more than to have the beautiful mare all to herself, and the resulting chaos forces Celestia to call a psychologist to sort out Luna's multiple personalities.

Canterlot... For centuries, Canterlot was the shining gem of Equestria, the pinnacle of pony society. Now, it’s a reminder, a bleak and monolithic warning to the world. 

Changed by the chemical and technological poisons that plague the mountain, an abomination of nature, I wander the greatest disaster Equestria has ever seen. 

... I will escape eventually, and when I do, I hope my friends still see me as Twilight Sparkle, and not the monster that hides among the ruins. 

When a spell by Twilight Sparkle brings the Achievement Hunter crew to Equestria what will happen? Will the crew be able to help ponies get achievements? Will they be able to help them get real life achievements? Will Geoff and Jack be able to keep their sanity? Will Ray and Michael be able to hold their excitement? Will Gavin continue to be an idiot? We might only be able to know the last one! Read on to find out!

A/N: This was just a completely random idea that popped into my head when I saw a picture of Applejack with Jack's beard being called "AppleJack Patillo." There will be no shipping or big adventures in this. Just a funny random idea. Enjoy and please if there are any mistakes do not hesitate to tell me! I wish to improve!
