Every new initiate to Starlight Glimmer's town has to spend the first week with the founder in her cottage. There's a deep dark secret to this, of course. Fluttershy's about to find out the hard way.

(Placed on a temporary hiatus! However it will NOT be forgotten, and will be updated once I have a few more chapters fixed and polished.)

The day we opened the portal was the day we opened the gates of Tartarus and unleashed an unending horde of flesh eating abominations which quickly gained 'control' of Canterlot, devouring its residents.

Some were lucky enough to simply die while other unfortunate victims rose up as emotionless monsters, ready to follow the mindless horde in search of warm blood and fresh meat to sate they're new never ending hunger.

Now they march across Equestria with the goal of devouring anything they can get their bloodied hooves or hands on.

And I'll be damned if I let myself or Spike fall into their cold, dead grasp.

When Princess Celestia asks Twilight to make an official, royal visit to Romaneia, Twilight dreads the inevitable succession of dry, boring diplomatic events. The charming Lord Bela soon wins her over, but Twilight is about to discover that all is not as it seems in Bela's apparently peaceful castle. (A story inspired by Carmilla, Dracula, and other classic vampire tales.)

Written for the BadassTwilight = Total Domination Twilight's Nightmare Halloween contest.

(Spoilers in comments.)

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

Twilight, my Faithful Student, my friend, if there is anypony that can create a world of Harmony, true Harmony, it is you.

More than a thousand years ago, my sister and I sought to create a perfect world, a world ruled by Harmony. A world free of evil. We were powerful and believed ourselves above the laws that governed this world. But this world is governed by the laws of Magic, and Magic, it seems, demands balance.

Where there is Light, there is Darkness.
Where there is Order, there is Chaos.
For there to be Love, there must be Hate.
For every Dream, there is a Nightmare.
Each begets the other.

And like boiling water over a fire, each can extinguish the other.

I should not have been surprised when the day came that the evil I had to fight was my own sister. It was the world restoring the balance we so foalishly ignored.

Perhaps, it is for this balance that I now stay my hoof. I have chosen to have you,Twilight Sparkle, act in my stead as the evils I thought vanquished, inevitably return to Equestria. It is in hopes that you may learn this balance, that you may learn from my mistakes. It is not something I alone can teach you, when I myself still understand so little. It is why I must now rely on the help of an old nemesis.

He intends to take you away, my protégé, and make you his own. You must not succumb to his influence. Yet if you are to learn the balance that is at the essences of all things, it will be through him. For the future of Equestria and for the sake of Friendship, you must prevail.

I hope that some day you can forgive me.

It all started out as a silly idea; trying out to be a Pony. One thing leading to the other. I apparently went all the way. Now, I had to live with it, there is no way out.

You start with trying out the gloves and stockings. Or you try the panties and top first. Or you could try out any other combination. Eventually you have them all on. This is the fun part.

Only now I had tried the muzzle on, and it is when the changes stick. I had made it fuse to my face. Now I can't get it off.

This is where the adventure began, as they say. Only a Pony can't live alone, thus I'm happy, not being forced to this consideration in the first place.

Stumped on the mystery of the locked box, Twilight begins to get frustrated. When Princess Celestia suggests to Twilight to visit her old castle, she jumps at the opportunity to make any type of progress. Little did she know she would get a lot more than she bargained for...

Basically this story is a mix between Castle Mane-ia and Bats!, but with a dark and interesting twist. Join Twilight and her friends as they brave the thousand-year-old castle and unearth its ancient mysteries while escaping a sinister, unknown threat. Will the ponies be able to escape the clutches of darkness? Or will they be morphed into a shadow of their former selves?
