Twilight's P.O.V:

I took in deep breaths after Sombra ended the nightmare spell. It was like the nightmare that I had while I was sleeping, but much worse.

This time the nightmare went on to show Celestia turning into Daybreaker, laughing evilly, and killing me.

I tried to put a shield around myself as Sombra's horn started glowing, but that only gave him an idea.

He said, "Now, we can't have you using magic, can we?"

Without waiting for an answer, he took all my magic from me.

I screamed and when he was done drinking, he had grown taller, and his fangs had grown longer and sharper.

I yelled at him, "Give my magic back, you tyrant!"

"I shall not give your magic back. Let's see how strong you are without it."

He came closer to me and messed my mane. I tried to buck him, but I had no strength. I felt weaker than before.

An evil grin on his lips, he said, "I think you need more than just nightmares."

He licked his lips and then sunk his fangs into me. I screamed in pain, but he used his magic to seal my mouth shut.

He began drinking my blood as a vampire would do.

He drank more and more, and he left a little bit of blood, just enough for me to survive.

I fainted.

King Sombra's P.O.V:

After the mare tried and failed to buck me, I got an idea.

I sunk my fangs into her neck to show her that they were not for decoration.

I was a vampire. Her blood did taste good; I hadn't drunk any for a thousand years.

It was so hard to stop, but I knew that I had to or else she would die, and I wouldn't be able to do my plans with her.

I had many plans for this mare. If she used to be Celestia's student and was given the task of saving my Crystal Empire then that meant she was talented with magic.

I looked at her fading cutie mark and saw that it was stars.

And if she was the element of magic, that meant a lot.

My original plan was to torture her, kill her and then send her dead body to Celestia in a gift box wrapped up with string.

But then, I had thought more about it and decided to make her loyal to me.

If I kept torturing her like this, one day the mare would need a push and she would break.

A single word could break her if aimed carefully. This was going to be so much fun.

I put a nightmare into her dreams. It was about Celestia.

I would give her nightmares about the ponies closest to her becoming evil and wanting nothing more than to destroy her.

I did it very carefully and put enough energy into it to make it seem real.

I teleported her into her cage and locked it.

Then, I decided to eat something.

Half an hour later found me in the dining room, eating roast chicken. Unlike other ponies, I was an umbrum and ate meat.

Ponies thought it terrible to eat a living creature. But I didn't.

After eating, I washed my hooves and my muzzle, dried them, and decided to have a walk through the empire.

I put a spell on the castle so that nopony could go in or out. Then, I started my walk.

All my slaves were mining, every restaurant and home was empty.

They had been mining for a whole day now without any rest. But I didn't care; they deserved this fate.

I thought about the mare who had betrayed me, a thousand years ago.

Perhaps Radiant was dead by now. She was lucky. If she had stayed in the Empire and stayed alive, I would've tortured her until she begged for me to kill her.

How I hated her. I still wondered, did she ever become a princess?

I shook my head; she was unworthy to occupy my thoughts. The betrayer.

I so wished that I could find her dead body, just so that I would be able to rip her horn off and add it to my collection of unicorn horns.

All the unicorns in the Empire had their magic drained and horns ripped off by me.

I even had a collection of pegasi wings.

I had put mind-controlling spells on some pegasi and unicorns to be my guards.

I didn't do it on the other ponies.

It was amusing to see the fear in their eyes.

*****************************************************************

Sunset had happened a long time ago, and I was in my castle, in my room, looking at the miserable mare in front of me.

I decided that nightmare spells weren't enough, and I tortured her physically.

She now had cuts and bruises all over her body. She was flat on the crystal floor.

I looked out the window and saw the Empire starting to turn into a frozen wasteland.

I got an idea. Before my banishment, I had been working on making a dark crystal heart.

I levitated a wooden box towards me and opened it. Inside was what looked like the crystal heart.

I had finished it, but I never had the chance to test it.

I teleported to where the heart used to be and put my dark crystal heart in there.

It spun in its place, taking in all the fear and hatred that was in the Empire.

Then, all the snow disappeared, and the ponies fur lost their colour.

Only my fur stayed its original colour. I grinned as every crystal in the empire became black.

The empire had finally lost all its beauty, love, and hope.

I teleported into my room and looked at the still unconscious mare. My horn glowed and a bucket of ice-cold water fell on her.

She opened her eyes and sat up. Then, she shivered. I decided to give her another nightmare about one of her friends.

I looked into her mind and decided to give her a nightmare about this Spike.

Twilight's nightmare:

Twilight Sparkle stood in her library with Spike. She kept trying to talk to the dragon, but the dragon turned away from her.

She tapped the dragon's shoulder and asked, "Spike, why don't you want to talk to me? Or hear anything I say?"

The dragon turned to face her and roared, "BECAUSE I HATE YOU, TWILIGHT! I HATE YOU! YOU ARE THE WORST PONY IN THE WORLD!"

The mare's expression was of shock. She cried, "Spike, why are you saying all those things?"

The dragon roared, "BECAUSE IT'S TRUE! YOU ONLY USE ME. YOU THINK OF ME AS YOUR SERVANT. YOU ARE A HEARTLESS BASTARD!"

"S-spike. That's not true."

"IT IS!"

End of Twilight's nightmare.

The purple mare couldn't hold her tears in. She let them roll down her face.

She was so weak after going through nightmares. So weak.

I gave her a few minutes of peace, before starting another nightmare.

This time it was about the apple pony.

Twilight's nightmare:

"A-Applejack, what are you saying?"

"What ah'm sayin is that you're the worst friend a pony could ever have."

"H-how could you say that?"

"Oh quit your stutterin. You're pathetic, ya know that? You're a terrible excuse of a pony. Ya aren't even worthy enough ta be the princess' student."

To make it clear, AJ kicked Twilight, hard on the face. Twilight was now bleeding.

The mare raised a hoof to her face, unable to believe that her friend had bucked her. But it was true.

End of Twilight's nightmare.

I ended the nightmare and got an idea. Every month, I would give her a nightmare about her close friends betraying her. That seemed like a good idea.

*******************************************

One month later...

King Sombra's P.O.V:

"Are you ready for this, mare?", I asked as if I cared. I didn't care at all. Without letting her answer, I cast the nightmare spell, and she screamed in horror.

Twilight's nightmare:

In the Everfree forest was Twilight Sparkle, and Rainbow Dash. Rainbow was saying, "You know what, Twi? I HATE you."

"What do you mean, Rainbow?"

"You are stupid, and an egghead. All you do is just read books. You don't CARE about ANYPONY and NOPONY cares about YOU."

"Rainbow..."

"Remember that time when we went on a trip together, and Fluttershy was scared? All you did was tell her that we needed to stay on schedule. You didn't even care about her."

"Rainbow, I can explain..."

"No Twi, I've been waiting too long. Say your last words."

"What are you going to"

The unicorn's sentence was cut short as Rainbow Dash threw her off the cliff. Twilight screamed, and splatted on the ground.

End of Twilight's nightmare...

I ended the nightmare, but little Twilight didn't stop screaming. In the end, her screams were so loud that I kicked her hard.

******************************************************

A month later...

I smirked seeing the scared Sparkle. She was very afraid of what she'd see today.

I started the spell and watched.

Twilight's nightmare:

Twilight was in Pinkie pie's shop, trying to talk to the mare. But Pinkie ignored her completely.

Twilight tapped Pinkie's hoof for the 1000th time, and Pinkie ignored her.

Once the mare had finished her work, then she said, "Twilight just go away. I don't want to talk to you now."

"But Pinkie this is important!"

"And so was my sleepover last week."

"What sleepover?"

"The one you never joined."

"But you never had any."

"You never came to them. And that hurt my feelings."

Pinkie took a deep breath before screaming in Twilight's face, "SO YOU BETTER GET OUT OF HERE WHILE YOU CAN!"

Twilight didn't move, so Pinkie got a pan and made the first Twi-cake.

End of Twilight's nightmare.

The mare had a shocked expression on her face. I kicked her to give her more pain. She screamed.

**************************************************

The month after that...

Tiwlghts nightmare:

Twilight was standing still while Fluttershy stayed away from her as if she had some illness.

Twilight asked, "Fluttershy? Why are you standing so far from me?"

"I don't want to talk to you."

"Why not?"

The pegasus didn't answer Twilight question. Instead, she screamed, "I HATE YOU TWILIGHT! I HATE YOU! YOU ARE THE WORST PONY EVER! IT'S ALL BECAUSE OF YOU THAT ANGEL BUNNY IS DEAD! YOU MURDERER!"

Fluttershy turned into Flutterbat and hissed before attacking.

End of Twilight's nightmare.

I laughed, "You are so pathetic."

*************************************************************

Next month...

Twilights nightmare:

Twilight was with Rarity. But Rarity didn't seem her usual self. She was busy getting needles.

After getting her needles, Twilight found herself pinned to the wall.

Rarity started throwing the needles into Twilight, and the mare could do nothing but scream in pain.

Twilight asked, "Rarity why are you doing this?"

"Because I'm paying you back."

"For what?"

"You ruined the perfect dress that I had made."

"What dress?"

"Don't act like you don't know."

"But I don't know."

"Quiet."

"Rari-"

Twilight couldn't finish her word because RARITY slapped her hard.

She said, "I HATE you, Twilight Sparkle. I hate you. I don't want to see your face again."

End of Twilight's nightmare.

I asked sarcastically, "Getting some pain?"

While the mare was having the nightmare, I had put needles in her body for real.

She looked at herself and saw the needles. Then she tried to pull them out, but she couldn't. The more she pulled, the deeper they went into her body.

I laughed and said, "Don't pull them or they'll go deep enough to touch your heart."

She stopped at that.

Author's Note

Author's note: I got the idea for the dark crystal heart from a comment by https://www.fimfiction.net/user/388657/Dragoknight92 which was 'More like the Dark Crystal Heart if you ask me'.

This chapter had a lot of nightmares. I wasn't patient enough to write 1000 nightmares, and I wanted to get started on the dark stuff as soon as I could, so I decided to write the nightmares about the mane 5 and Spike hating Twilight.

This chapter could've reached 2000 words. I hope you liked this chapter, and before you go, don't forget to...Vote...Like...Comment...Share!
