It was a golemn, run by a fairy. The golemn would run as long as the fairy was alive, but would die when it did. The golemn opened it's stone mouth and a fairy exited from the chamber it would be attached to.

She was small, even for a fairy. Her dress seemed to almost fall off of her, but she kept tugging it back into it's proper place. Her face was smeared with dirt and grime, and her purple eyes gleamed in the dim light.

"Ooh! Ponies should not be here! What if her Majesty found you? Hmmm? What then?"

My mouth dropped open, how could she talk? Most fairies had been silenced by powerful spells since birth 'so their loud voices wouldn't bother her Majesty'.

"What is that?" Rarity demanded.

Pinkie Pie bounced forward, "It's a fairy, silly!" Everyone, I included, stared at her in open amazement. Pinkie Pie thought for a moment, "We need to sing!"

I groaned, and so did Rainbow Dash.

"Don't get me wrong,

I know we don't look very strong.

We won't get hurt by a teeny fairy,

Even if it looks weak and hairy-"

The fairy didn't look impressed. Nor did anyone else, for that matter. Pinkie giggled, "I thought that would work!"

I sighed, but before anyone could do anything else, the fairy flew back into the golemn. I stepped back, thinking about what magic I could use on it.

I could kill it. It would be quick and painless.

As the golemn creaked to life, everyone backed away. Spike clung to Rarity, and Fluttershy was attempting to hide behind Applejack.

I thought quickly, but couldn't think of the proper spell. Panic surged in my head, and felt the pressure mount behind my eyes. I squeezed them shut, going through the ancient magical words, seeing if I could make a spell that would accomplish the task.

The golemn swung madly at me, breaking through my thoughts. I yelled the first spell that came to mind: a very dark spell. It would cause the victim unimaginable pain for as long as the caster was chanting the words.

The fairy screamed in agony, and the golemn crashed to the ground. The golemn started thrashing around, and I continued the chant.

"Sweet nibblets!" Applejack yelled.

The black magic coursing through my veins made my heart race and brain fog. All I could think of was the chant, and how good the magic felt. A little voice in the back of my head was telling me to stop, telling me I should stop before something bad happened.

Suddenly, the screaming and thrashing stopped, and the magic abruptly stopped. It left me feeling cold and sick. Slumping to the ground, I finally realized what I'd done.

I had killed something using the blackest magic I had available. The aftereffects of such a dark curse, coupled with the blood magic earlier used, made me feel dizzy and lightheaded. I and watched in despair as blood started to seep from the golemn's eyes, mouth and nose.

I heard the sounds of several of the other ponies vomiting. I felt very much the same, guilt building in my chest. My breaths became laboured as pain, guilt and terror began to take hold.

"She's going into shock!"

My vision gave one last lurch, and I felt my head rush to meet the ground.

(LINE BREAK)

"Don't let her go!"

"LET ME GO! TOBIAS YOU BASTARD!"

"You've used too much, you killed the informant. Do you understand what's happened?"

"I CAN'T HAVE! Celestia said the magic was fine!" I whined, moving my head to stare at Tobias in shock, "She said it wouldn't hurt anyone."

Tobias brushed a hand over my forehead, moving the sweaty black stands from the sticky skin, "You still trust her? How? You were a guinea pig, we rescued you and you left willingly. Do you remember why?"

"Something was wrong there, I don't know what-" I broke off, "The magic has never-"

"Eternity! Do not lie to yourself. You've been gone for so long, we never thought-"

"Please! It's all I have!"

"Eternity!-"

Tobias smiled, and turned to the other ponies in human form that had escaped with me, "Let her go. Go talk to Sparkle. He'll give you the tour."

The others nodded reluctantly, and left, "Eternity. I'm sorry, but we can't let you use magic until the black magic has stopped polluting your mind. This means little contact with others and you won't be able to leave the rooms we give you."

I shook my head, "nonononononono! I am not trading one prison for another!" I paused, stunned at the words that had left my mouth. Why had I said that? Why? The Princess had put a roof over my head, gave me food. All I had to do was worship her like the absent gods my parents had before. All I had to do was offer my body and soul-

"Eternity!-"

Tobias watched my internal struggle, and kept his hand on mine, "I know you can do this. Do you want to be alone?"

I shook my head furiously, making myself dizzy, "No! I-I can't stay here! Her Majesty will be disappointed!"

Tobias sighed, and pulled his hand away. He moved to the panel near the door. He pressed a button.

"This is Tobias. I'll need help moving her to her rooms. Bring strong ponies. She'll fight."

Panic rose in my throat, I needed out. I needed Celestia's guidance, needed her wisdom. Needed something, someone, to believe in. To give my soul to, to blame if things went wrong-

"Eternity!"

I shot up off the floor with a strained yell, sweat pouring from my skin. Shooting panicked looks around the room: I saw six ponies, and a pool of blood surrounding a downed golemn, it looked old and worn, no wonder why the fairy died-

Then it hit me. My mouth went dry, and I scrambled away. My heart in my throat, I looked around again.

"Woah Nelly! You alright, sugar-cube?" Applejack asked.

They're all gone: Tobias, Sparkle, the others. The memories that hit me, even if incomplete made me nauseous.

Sparkle, screaming as dragon fire melted his flesh from bone.

Tobias, wasting away from infection. Despite all our efforts, even after we amputated his leg- he died.

"Are you okay?"

I looked up from the cold, hard, stone floor, "No, but I will be."

I enjoyed writing the last part of this chapter. Not exactly what I had in mind for the end, but I just followed where Eternity took me.

It's been brought to my attention that some of Eternity's inner dialogue doesn't make much sense. I have to point out that that's the point. Eternity is not quite sane, and even though it makes sense to me (and her) it may not to you. If you have any questions or comments, you know what to do! PM or review and I'll see about answering. Happy reading!
