This was an idea I had a while back over at Cafana's house. I ended up stealing her computer and typed until 2 in the morning. My eyes still hurt... It's my first story here. :D Criticism and feedback is perfectly okay!

Prologue

No one seemed to notice the odd man who stood out in the streets. I couldn't help but stare. Everyone was going about their usual business, so busy, but not him. He stood still, eyes nervously glancing back and forth. For some odd reason, this one man seemed familiar to me. Why didn't anyone else notice him?!

His eyes landed on me. At first, he walked slowly, but soon broke into long strides. And then I recognized him.

Matthias Walters, age 27. He had disappeared almost a month ago after the death of his girlfriend. He had once been a very respectable man until he was finally driven insane. He had vanished. He was back and heading right for me.

I turned and started walking like I had something to do. My hand lay on the deck of cards in my coat pocket. Cards would do nothing to help me, but it was reassuring to have some kind of memento of my life. Screams sounded in the air. At first, I didn't want to look. I turned anyway, mentally cursing myself for being so stupid as to do so.

A machine-like-ball thing stood where I had last seen Matthias. It was shooting out these odd red bullets. One narrowly missed my head and drove into the wall. It was all just so...weird. I felt detached from the whole thing. That is, until one of those red bullets hit a lady who was trying to flee. At first, I saw nothing but a huge hole where the bullet had gone through her body. Then her skin turned red and she turned to dust. Only the clothes remained. A cloud rose up. I gagged. That had to be the most disgusting thing I had ever seen. A deep desire to destroy the thing filled me, but I didn't know how. I had no weapons on me.

Something was vibrating slightly against my side. I searched through my pockets frantically before the thing noticed I was still alive. My hand touched the deck of cards that was tied with a cord. My deck. It was the source of the vibrations. I pulled it out. The whirring grew louder. I looked up and saw the machine-thing coming towards me. It had found me. Fingers trembling from fear, I tried to untie the deck. I couldn't. Suddenly all of its guns were trained on me. Fear paralyzed me. My mind told me to run. My body wouldn't respond.

It fired. I flung up my hands to protect myself. It would've done no good, naturally, because of the lady I had seen who had just turned to dust and vanished.

Nothing hit me. I lowered my arms to see cards surrounding me- my cards, just bigger, about my size. I reached out to touch them. It was real. The deck was no longer in my hands. Eventually I understood that I had to fight with these. The machine was becoming annoyed. I flung my arm out in its direction.

"Do whatever that needs to be done to destroy that thing!" I yelled. As if it were telling me what to do, I knew which move could destroy it. There were a few, but I only needed one. "Three of a kind! Cutting Wind!"

Three cards detached from the rest and broke into small pieces. It whirled around and around until it finally whipped itself around the machine. It was truly a cutting wind. The tiny pieces were miniature blades. It exploded. The cards returned to normal size and settled into the palm of my hand. I stared at them in shock. What had my cards done? They acted of their own accord and attacked the thing threatening my life. No, they acted off of my wishes. I wanted it destroyed, to vanish, to have whatever was possessing Matthias gone. Now nothing was left of Matthias.

I wanted to learn more of what those machines were and why the cards in my hands could destroy it. Lucian had given me these cards. At the time, nothing had seemed wrong with them. Now they were a weapon.

My weapon.

The world was not as peaceful as it seemed, and I was determined to find out why.

So, how was it? Constructice criticism and stuff like that allowed. If you give me flames, it'll be given to my best friend who will use it for her own purposes (I'm not asking what they're for). Please wait patiently for chapter 2!
