Chapter 1: The Kill & The New School

Riley's pov

My name is Riley Thorn Reaper but I'm also know as; The lil Reaper, Hatter, baby girl (fathers nickname) and Wolf. Today I'm on my way to London to meet up with a client. Father is back home teaching my new class how to be assassin's. Yes I'm a assassin. I been in training since I was two and my first kill at the age of five. I'm very good at what I love to do. My own father is know as the Grim Reaper the best out of all of the assassins in the world. He is my hero and I wasnt to be just as good or even better then him. I never knew my mother, cause she died while giving birth to me. Father say's she was beautiful but very deadly. I asked him if she was a assassin but he said no. I still don't understand how can she be deadly if she wasn't understand how can she be deadly if she wasn't a assassin. Father wouldn't tell me, so I just stopped asking. I've tried to look her up but its like she was never here. I couldn't find anything on Alice Thorn. Something told me I will be finding out soon who my mother really was. So for right now I'm landing in London and I have to go across town. I hate cars and I don't know why. Plan's I'm the same way but its the fasters way to travel. I started to walk with the crowd of people. It took me tweenty minutes to get there. I walked into the building and every one looked at me as I walked over to the lady behind the desk. She looked at me confused. Why would a 13 year old be walking into a business office for? "Hello how can I help you?" she asked as she studied my face. I smiled back at her. "Hello. I'm here to see Mr. King." I said and she chuckled at me. "Sorry but Mr. King is not seeing any one to-" I cut her off. "He asked me to come before two. So you call him or I leave and you can tell him why I'm not here." I said with out a smile. I could see the fear in her eyes. Then she got on the phone. "Mr. King a girl is here to see you." she said. Who is she? he said and she looked at me. I moved in a little so she was the only one that can hear me. "Tell him the lil Reaper is here." I said and she told him. Send her up now! he yelled at her. I smiled before I left her staring at me. When I got to his office he was stadding and pacing. "Welcome. What should I call you?" he asked me. "Call me Anny please." I said and he nodded. I never give my name or let them see what I really look like. That's right I'm wearing a wig, contacks and other stuff. If some how they can get my name they wouldn't know what I look like. "Who is my target?" I asked Mr. King. "The other guy I'm running against. I have everything you need in here. How much will it cost?" he said to me. I looked threw the file. "500,000 yen." I said and he looked at me. "Sorry convert that into pound's it will be 2, 952.96 pounds." I said and he looked at me. "I can to that. How ill you take the payment?" he asked me. "I would wire it but I will take cash but unmarked bill's and I will take it now before I do the task." I said and he looked at me. "Ok. Give me a few minutes." he said before he left. I looked threw the file again. It just had a Picture of the guy and a little stuff about him.

When he came back with my money I left. Before I kill I make sure they are worth killing. So I put my money in one of my many banks. I don't keep all my money in one bank. I watched Mr. Helix for a few day's, listened to the people around him talking. Then I started to poke around to see if he is really good. So till the speach day I looked for everything about him. Now I'm on top of a building with my home made sniper gun ready to kill. Then both of them walked on the stage. I took aim and took a deep breath then pulled the triger. My bullet hit Mr. King in the head. I don't kill good people and Mr. King is evil. So he payed me to kill him. With that done I packed up and left. Dad is coming today to take me to see my mothers grave. She is burried here cause that is what she wanted. I went to meet up with him in a few then we head over. As I walked I got this weird feeling somethiing is watching me. I said something and not someone, cause this feeling didn't feel like a normal humen. "Did you hear what just happened at that muggle thing?" some one said next to me. "Yea, muggles killing each other is something." said his friend. What the hell is a muggle? I thought cause I never heard that word before. It took everything I had not to bust out laughing, cause they are in weird robes. I never seen people like them before. But they are giving off something that feel's the same as that things following me. I started to walk again, then I saw my father. After what happen to him he stuck out a lot so it's not hard to find him. With a smile I walked over to him. "Day!" I called out and he turned to look at me. "Baby girl!" He said as he gave me a hug. When I called him dad every one turned to looked at me weird. "How's my baby?" he asked me and I shook my head at him. "I'm fine. Let's go." I said before I pulled him with me. "How did it go?" he asked like it was nothing. "Good but a rat was trying to get a child so I had to kill it." I said. "I see. They been doing that a lot." he said to me as we walked. We have codes that mean something else so no one will know what we are really talking about. We got to the place and no one was around. As we made out way threw the grave yard the person is still following us. We stopped at my mother's grave. I looked at her head stone. I really wish I got the change to meet her. "You ok baby girl?" he asked me, but before I could say anything the person was moving towards us. I turned around with my gun pointed at a old man with a white beard. He looked shocked but then he smiled at me. "Professor Dumbledore what are you doing here?" dad said and I looked up at him with shock. "You know him?" I said to him. "Yes he was your mothers headmaster at her school." he said and I lowered my gun, then put it up. "I felt Riley's power and I followed her so I can talk with her." Dumbledore said to my father. "You want her to go to that school of yours right?" dad said lke he knew this was going to happen. "Yes. She need's to learn to control her magic. Besides Alice wanted her to go." I looked at him more. I really don't know what is going on. "I know but she never showed a sign of magic so I didn't think she had any." dad said. "Can someone tell me what the hell is going on?!" I growled at them. "Sorry Riley. Your mother was a witch. When she turned 11 she got a letter and went to our school. I been looking for you since you turned 11. Now that I found you. Do you wish to go to the school your mother wanted you to go? There you will learn what you are and make friens." the old mad said to me. I looked at my dad. "Its up to you baby girl. If you go you get to learn what your mother was and get closer to her." he said adn I looked at the old man. "I go but what do I need for this school?" I said to him. He smiled at me. "When your done with your visiting your mother. I will take you to Diagon Alley and how to get in." he said. I turned back around, then I pulled out a small little wooden wolf that I made. Dad said my mother loved wolfs, so every time I come I would bring something of a wolf. I placed the dark wooden wolf next to the other's. Dad placed a tentacle on my shoulder and I looked up at him. I can tell he is sad too, but we don't show it much. . .will I don't show it. Dad started to when he became a Professor. I turned back around to look at the headmaster. "I'm ready." I said to him. He nodded and then we followed him back into town. It took us a while to get to the place. "What's the Leakey Cauldron?" dad said and Professor Dumbledore looked at him with shock. "You can see it?" he said and I looked at him. "What do you mean sir?" I said. "Well non-magic people can't see the but, cause there is spell's that keep them away. I wounder why he is able to see it." he said but the last part it sounded like he is talking more to him self then to us. "Do you know what a muggle is?" I asked him as we walked threw the pub. "Yes I do but how did you hear about it?" Professor Dumbledore said. "I heard these two guy's in robes say that word just don't know what it means." I said to him as he pulled out a fancy stick then tapped the brick wall. "Muggle is a word our kind use's for non-magical people. So if you hear anyone use it, its a good change they are a witch or wizard." he said. Then my mouth fell open, cause the wall started to move out of the way to make a arch way. On the other side is buildings but weird one's that I never seen before. But the people are dressed in robe's but the kid's are in normal clothes. "What is this place?" dad and I said at the same time. "This is where you are going to get your stuff. If you follow me I take you to Gringotts." he said and we followed him. I looked at allof the shop's. So many thing's I never seen or dreamed was real. Then we came to a huge building and started to walk up the stairs. I have my hand on my huge knife.

Cause there is small ugle things walking around. "Don't worry Riley they are goblins and they work here." Dumbledore said to me. I nodded and moved my hand away as we walked up to a goblin. "Hello, Miss Thorn would like to get money out of her vault." Dumbledore said and ever goblin stopped what they are doing and looked at me. "I didn't know there was any Thorn's left." the goblin said in a low deep loive as he looked at me. I looked back at him and I saw something changed in his eyes. "Alice Thorn gave birth to Riley and died." Dumbledore said to the goblin. "We are going to need some of her blood to make sure." he said and I held out my hand to him. He looked at me as he took out his own knife and then cut my finger. I didn't blink when he did that. Every one watched as he took my blood. I pulled my hand back after he had my blood. "Let me heal you." Dumbledore said. I gave him my hand and he pulled out his stick and touched my finger. Then it started to heal. I would have healed in the nest to minutes. It didn't take the goblin long to come back. "Riley Thorn you are the last of the Thorn blood line. Please follow me, I will take you to your vault." he said. then the four of us went threw a door and got into a cart. Then it took off fast. Dad put his tentacles around me. I smiled as we went deeper down. It took us a while to get down to my vault. We got out in front of a huge old metal door. I saw demonic wolf's on the door. They watched me as I looked at the door. Then I touched the door and I still had blood on my had when I touched the door. Then something went threw me. Thorn by blood and birth. Those who are on the list shall fall by our blade. Now open and let me in! I said but it sounded like I was talking in a different language. I speak 42 different language's, but this one I have no clue what language I just spoke. When I spoke the word's the door opened up. My mouth opened like a fool when I saw what was on the other side. On the other side there is huge piles of gold, silver, bronze and jewls. "Here's a bag Riley. Put the gold, silver and bronze in the bag." Dumbledore said to me. I nodded my head then did what he said. These vault is huge there is so many piles of everything. I got a good look at the back of the vault, I can see armor, weapons, and other cool things. Once the bag was filed. We went back up. Dumbledore told me about the three different kind's of coin's. Galleon's, sickle, and knuts. Its easy to understand the money. "We got out of school last month. If you can we can go to the school and I can teach you what you have missed?" he said to me. "I'm a fast learner so lets do this." I said then we got all the book's and other stuff I neened for the first two years. Then I said my good-bye's to my dad. He took off and Dumbledore gave me a black leather bag-pack that was my mothers when she was in school. There is a spell on the bag that is huge on the inside and it don't weigh alot. All the stuff I got is in this bag. Besides this bag will come in handy on my missions. Then he told me to take his elbow and I did. Then he turned and then I felt the worst feeling I ever felt. It felt like I was being squeezed threw a pip or something like that. I couldn't breath then it was over as soon as it started. I was still on my feet breathing hard. "These was your first time appariting and you are still on your feet." he said and all i could do was just look at him. He smiled at me before we started to walk. After a while I started to feel better. "Do you always feel like that?" I asked Dumbledore. "No you get use to it. It's a fast way to get to no place to another, but it can go very wrong if your not careful." he said. "What can go wrong?" I asked. "If you do it wrong you will splinch." I looked at him. "What is splinching?" I asked him as we walked on. "Splinching is when you leave some part of you behind." Dumbledore said and that sounds painful. "I see. What are other way you can travel?" I asked him. "Floo powder, you take a pinch of it and throw it inot the fire. Then say the name of the place you wish to go. Then broom's and Thestrals." he said. "Brooms? Really?" I said with a smile, cause a flying broom would be good. I can use a flying broom on my missions. Shotting from the air will be easier and harder to figure out were the shot come from.

"Yes really Riley. Broom's are mostly use in out world." he said as we came to something huge gates. "This is Hogwart's. I hope you will like school." Dumbledore said as the gate's open. My jaw dropped when I saw the castle. "Wow." was all I could say. "Before we get started on your training let's see which house you are going to be in." he said and I had no clue what the hell he is talking about. As we walked he told me about the four different house's and I will be in one house. "What house was my mother in?" I asked him. He looked at me and for a splite second I saw sadness in his eyes. "She was in Slytherin." he said with a smile. "Oh so will I be in Slytherin as well?" I asked. He stopped to look at me. "I don't know. Every one is different. You might but then again you might not. Have to wait and see." he said and we started to walk again. The inside was just as beautiful as the outside. I followed him up to his office. "Pleace sit down Riley." he said and I did. I watched as he took down a old hat. I can smell the magic on it. That feeling I was getting was magic and I can smell it as well. "I will put the hat on your head then it will say which house you will be in." Dumbledore said and I nodded. Then he put the hat on me and it went over my eyes. A voice spoke in my head. Hmm another Thorn. . .but you aren't like the other's. You must be Alice's child. he said but he had sadness in his voice. Sorry I like your mother. She was different from the other Thorn's. I can tell you are very different from your family, but you have the heart and soul of your mother. She should have been in Gryffindor but she chose to be in Slytherin. You have every thing that it take's to be a Gryffindor, but if you want to be in another house you can. he said. I didn't know so I will let the hat pick since he know's what's right. You will like Gryffindor Riley. he said to me. Then Gryffindor it will be. I thought to him. "Then Gryffindor it is." he said out loud. "That's good. Riley I will show you, your commin room and then we can get started." he said as he took the hat off. After he put the hat up, then we left his office and went up the stairs that moved. The stair's wasn't the only thing that was moving. The paintings are moving and talking. "How can they move?" I asked in aww. "It's a potions that make's paintings and picture's move." he said and I smiled more. "I never thought that could be possable." I said. "Magic can do a lot. This is your commin room." he said as we stopped in front of a painting with a fat lady in a pink dress. "Welcome Headmaster." she said to him. "Thank you. Gun will be the password for the summer." he said and she nodded before she swong open. Then we crawled threw the hole. "This will be your home while you are here. The password will change and your perfec will let you know what it is. Your room has your name on it. That will be your room while you are here." Dumbledore said to me. "Go put your stuff in your room and make sure you bring you wand." I nodded before I walked up the stairs. Then I saw my name on a door, but there are three other name's on the door. One of the name's stood out. "Lily." I said as I walked into the room. I can smeel three other scents in here. The only bed that had no scent must be mine. I put my bag on the bed and pulled out my wand. It feel's really weird holding this stick. The guy at the wand shop said. Your wand is 12.5 yew with the core mix of dragon heartstring and phoenix feather. The wand us kibger tgeb average wutg a flexible and long-lasting wood. Your wand is ideal for jinxes, hex and fighting. he said when I finally got chosen by my wand. He said that this was the first mixed core wand he ever made. He never thought the wand will ever find a home. I jumped down the last few step's. "I'm ready." I said before we left the commin room.
