The Darkness Of Crystals.

I decided that was enough, and ended the nightmare. The mare cried and cried. "See," I told her, "They don't want you. They think you're a mistake. Even Celestia abandoned you."

"Princess Celestia will rescue me!" Twilight said defiantly.

"Sweet little mare." I laughed, "Why would she rescue you? After all, you're a useless filly."

"She will rescue me. Because I am her faithful student!" Twilight said proudly.

"Really? Listen, mare, I could teach you more things than that pathetic excuse for a alicorn ever could."

"Don't you DARE insult the princess like that!" she screamed, "And I will never join you! I would let you kill me in cold blood than betray the princess!"

"Perhaps we have a lot of training ahead of us." I grinned, "Let's see how long it takes for a mare to break."

She slowly got on all fours. "I will never break," she said with a determined look in her eyes, "Princess Celestia will come for me."

"The Princess will never come for you. If your friends can even get the message to her."

"M-my friends will get to her! Princess Celestia and Princess Luna will come and stop you!"

"I have a lot of fun to do with you..." I grinned darkly. "Let us begin session two, then."

My horn glowed with dark magic, and once again, the mare was crying, begging and screaming.

I sat on my throne, watching her, and laughing. It was so easy to regain control of my Empire. Celestia had sent a weak filly, a filly to try and stop me.

It's almost like she wanted me to win. And her student, would become mine. Totally mine.

If a pony sees something again and again, they slowly start to think that it is real. If they see a nightmare of their closest ones betraying them, over and over again, they think that it is real.

And that was what I planned on doing to Twilight Sparkle. She would slowly believe that everypony betrayed her, and when I would be the only one there to comfort her, she would join me. It would take a long time, but it was all worth it in the end.

This time, I kept the nightmare spell on for two full hours. When I stopped it, Twilight couldn't stop crying. I said, "They all hate you. They don't want you. All of them want to see you dead."

"That's not true. They would never want that, ever." She tried to stop crying, "Princess Celestia will come and stop you."

"Oh come on," I laughed, "Celestia thinks you're dead. How long did it take for your friends to abandon you? They only stayed near the destroyed tower for five minutes, before the rainbow one yelled, 'there's no way Twilight could've survived that.' And then all of them left, not even trying to find your body."

"I don't believe you." She weakly said, "P-princess Celes- Celestia will come and save me. She and Princess L-Luna w-will stop you."

And with that, she collapsed on the floor, exhausted. I was determined to break her, so even in her sleep, I would not give her any peace. I made her dreams into a nightmare, one that would scar her permanently.

I whispered into her ear, "One day, Twilight Sparkle, one day you will break. And only I would be able to mend you."

I looked out of the window, and seeing that it was night, decided to get some rest. I dragged the mare to my room, and put her in a cage that was made just for her.

Doing that, I locked the cage and climbed into bed. It was a very soft one, the type that only Kings used. Thinking of the softness of the bed, I shut my eyes and slept.
