AN: Hola! Bonjour! Hello! It's me, mrsnessieblack! This is my new fanfiction. Duh! Enjoy!

Prologue: Twilight

"Move your arms," one man said. He was a good man, with a sweet voice. He also looked like a god. I did as he said.

"Now move your legs," another man said. He looked like a god, too. Everyone in here, save a regular mortal girl, looked like gods. I followed my instructions.

"Good," the third man said. He was the gentlest, the most kind. His long black hair looked like a hood. "Now, move your wings."

Everything was simple. I've done it for nearly a month. But I didn't know the people's names yet, or even my name. I flexed my long black wings.

Okay, here's what you missed throughout my whole one-month life. I woke up in a dark room. I was nameless. I was parentless. I wasn't even human.

The door to the room opened, and three men walked in. They told me that I was special. I wasn't human. They weren't either. They called me an angel. But that wasn't my name.

Basically, I've been living in this dark room for a while now. The men come to visit me every day. They tell me to do the same things, over and over again. I never really learned much.

There was one other like me. She had long brown hair, like mine, and large chocolate brown eyes. I don't know what color my eyes are. I hope they're the same as her's. Her's were beautiful.

Unfortunately, she passed by the only window to my room, and never lingered. I could never speak to her. I think my window is sound-proof. But I could still see. I didn't know then.

Every day, they would take her to the room alongside mine. I would watch as they took a needle and injected something into her. I watched as she fell to the ground, twitching, until she lie still. The men that took her into the room would shake their heads grimly and drag her by her arms into another room. I think they were reviving her, but I never stayed by the window to watch for her. But every day she would be perfectly fine, as if nothing ever happened the day before. In fact, she always looked a little curious.

Today was different, though. Today, they were letting me out of my room for the first time.

"I think she is ready, Aro," the light-haired god said, addressing the one with the long black hair. Aro nodded, clearly excited over something.

"Yes, Caius, I know. I can hardly wait. Marcus, will you tell Felix and Demitri that we will be testing Isabella X's durability?" Aro asked of the god with the wavy black hair. Marcus nodded and exited the room. Aro patted my arm.

"Isabella, I feel as though you're what we've been waiting for," he told me. "You are the tenth of your kind. We've been testing your reflexes for this moment."

"What is it that I have to do?"

"We will inject venom into you. It will hurt for a moment, but we believe you are capable of enduring it."

"How bad will the pain be?"

"If you wish it, I will have Alec erase your senses, so you will feel nothing."

"How bad-"

Marcus entered the room again, interrupting me.

"Demetri and Felix are ready," he whispered. Aro nodded and led me out of the room. I squinted at the sudden light outside. I was in the same room as the other girl. I watched her twitch, moaning, and then she was silent and still.

"Tis a pity," Aro whispered. "That is our ninetieth prototype. Felix, get rid of her. And come back quickly."

Felix nodded, and, along with Demetri, he dragged the prototype into the other room. I heard a gust of wind, and ten seconds later they came back, without the prototype. I saw a glimpse of the room before they closed the doors. The prototype was gone. I felt the heat from the room blow into this room. I gasped. They killed her. It was never the same girl! And I was next.

"Calm down, Isabella," Aro mumured as he lifted the needle. I winced as he pricked my shoulder. I felt the pain as he injected the venom into my body. I smelled the blood.

It smelled like rust and salt. It made me nausious. I felt faint.

I slowly fell to the ground. I wasn't twitching, I was just fainting. But Aro sighed.

"I had hoped..." he whispered sadly. "Felix, Demetri, destroy her, and her files."

Felix began to drag me into the room. The smell of blood wasn't as strong as my fear. In that instant, my senses were hightened. I felt the metal grate underneath me begin to heat up. I calculated that I had exactly ten seconds.

Holding my breath, I jumped up. Felix and Demetri both yelled in surprise. I picked up the folder that was destined to burn with me and let out my wings.

I have never flown before in my one-month-old life. I knew it wouldn't be easy. But I had to survive somehow, right? I jumped into the air.

I was actually pretty high up; about a hundred feet. But the large, towering shaft I was stuck in was higher. I unfurled my wings and gave them a long, steady beat. I was going higher. And higher! Oh, I was flying! I laughed excitedly and beat my wings harder.

The sunlight was brilliant. I squinted and flew off, looking down below. Children were running to catch up with me. Adults were either too busy to notice or were gaping at the strange creature with wings. I went up higher, so I was hidden among the clouds. I was free.

Landing by the beach on an old dock, I flipped through the pages of my folder.

Isabella X, it read.

A superhuman subject made to destroy vampires.

AN: How's that? I'm pretty amazed myself. I don't know why, but the idea was killing me. So I decided to write. Here ya go!
