Chapter 1: Unexpected Arrivals
Riley Stoll's POV:

I walked back into the cabin I had grown up in with my half-brothers/sisters. It would be hard to leave Camp Half-blood for this competition, Tri-Wizard tournament I believe they call it, but it would be worth it. My real brothers Travis and Connor were quite supportive of this; then again it's expected from them!

I should probably start from the beginning. Early this year a man called Albus Dumbledore wished to speak with us and offered us a, well an interesting prospect I guess. There was to be a tournament of theirs and Albus had recently come across the existence of Half-bloods, or better said Demi-gods, so he offered us the ability to go as one of the schools to enter the competition. Though, because in their eyes we're muggles, with no real magical ability, we'd be able to choose our champion. Over all we decided it would be fair not to send one of the big three's children, though they come to train our champion. Annabeth decided she'd rather help train the person chosen and then it went on and on, discussing who our champion could be.

I was chosen though; I would represent Camp Half-Blood for all the other people. So it was also in my hands to pick the team that would help me train… I was banned from taking my brothers though! So instead I chose a few people and each from a different cabin. Percy from Poseidon, Nico from Hades, Thalia from Zeus/Artemis, Annabeth from Athena, Clarisse from Ares and I was from Hermes. In all reality I chose the people I would want at my back if we were in a battle, people who definitely wouldn't let me down!

Anyway I entered the cabin, carefully stepping over all the things littering the ground, most of which would probably be stolen goods or traps! I was definitely going to miss life her at camp! I'd probably miss the pranks, the junk lying around and my family! I'd miss getting in trouble, cleaning the dishes with lava, running from the cleaning harpies at night and seeing Chiron's face after a prank me and my brothers would pull all the time. I was looking forward to a few things as well though! I was looking forward to seeing something other than camp as I literally grew up there; I've been there longer than Annabeth! I was also looking forward to being away from the memories of one of my other brothers, the brother I'm talking about, Luke. I missed him when he left, heck; I still miss him like hell. Seeing his typical grin, laughing while around him, calming him down when he went on a rant and then teasing him about things that happened to him. I guess I miss everything about him, which includes beating him in combat! I guess me and Annabeth are the only ones that hold onto hope though. We're the ones that believe that he's still good; we believe he's still in there somewhere. She does because she travelled here with him and went through a lot with him and I do because he's my brother and I can't bear the thought of losing him. Before I believe that he's evil, he has to break his promise. He has to break his promise not to hurt me or Annabeth and at the moment he's kept it. Instead of hurting me he held Kronos back so I could run, he blocked a blow that was going to hit me and in all this time he didn't do anything that could physically hurt me, only mentally and he didn't know that…

I arrived in Hogwarts rather late. The problem was that I didn't realize quite how long it would take me to run there with my entire luggage by that's fine with me, I still got into the grounds before the others did! They were given a type of object that would activate tomorrow morning England or Scottish time. I didn't really know which time I was going on, I just knew that I had arrived in one piece.

I entered the great hall and it seemed that he had only just given his speech. As they looked at me I suddenly found myself feeling self-conscious. And I though only Aphrodite kids were like that… oh well.

"Sorry I'm late sir, the plane was delayed and I misjudged the distance to this place so I had to set up camp on the way here!"

"Do not worry Miss?"

"Stoll, Riley Stoll sir" I answered with a small smile trying to ignore the feeling of misplacement. Everyone here was wearing a type of school uniform and then there was me. I was wearing my Greek battle amour and my blue horse hair helmet! Now if that doesn't make you stand out I don't know what does!

"Miss Stoll would you please refrain from wearing your helmet when your inside or when you're not training" he said in a rather kind voice.

"Yes sir" I said removing my helmet. I looked around properly then. The head of this school had a long beard and even longer hair! The length of his grey hair could rival Aphrodite's and that's saying something! He had glasses and also had the oddest style of clothes! Then again what could I say, I have been wearing Greek battle amour for most of my life, and on the odd occasions that I didn't I usually wore black pants a boys T-shirt and jumper 'borrowed' from somewhere or someone! Turning my attention back to his eyes I saw a calculating look, a currently unasked question shining in his eyes.

"How old are you Miss Stoll?" so that was his question…

"15" I answered confidently.

"You do realize that means you are too young for this tournament Miss Stole" another man close to Dumbledore said.

"I will have you know that Camp Half-blood decided that the children of the big 3 wouldn't enter for their unfair advantage of having more power, Annabeth daughter of Athena said she would help them train the Champion we chose at camp. The Camp chose me as my brothers; Travis and Connor are impossible to separate and would cause chaos here for not being able to have each other's backs here during the tournament. So we decided for the person who won a combat tournament would be chosen if they were also good at athletics and I'll have you know that I never lose! I am the best athlete in my cabin and also one of the best fighters. I also have good control over my powers and I am the most responsible person in Hermes cabin, also the most controlled as I don't have to pull a prank or steal something every 5 minutes. Along with that I looted the gas station with my brothers and hot-wired the camps van for them so I'm good under the thieving category!" by the end of my speech everyone was just looking at me. Sure I may be quite delicate looking but they haven't seen me fight and I have the right to be here!

"Prove to us that you are ready" the man with the hat said.

"Sure, Dumbledore could you please create a copy of the rock climbing wall here?" I asked sweetly. Sure enough he nodded not really knowing the dangers involved with the rock climbing wall until it appeared in the back of the great hall. I smiled at the familiar lava pool at the bottom, the falling boulders from the top and the lava spurting out of the sides of the chasms in the wall at seemingly random times. "If I climb to the top of this will I be able to enter the tournament like it was chosen at Camp Half-blood?"

"You can't expect me to believe that a muggle can get to the top of that!" the man with the hat said pointing up.

"Demi-god would be the correct term and yes I can actually. Just so you know, the boulders and the lava are both real so when I first tried this I almost died!" with that said I walked towards the giant copy of our rock climbing wall.

Thanks please review and give me tips and hints. Just so you know it's my first fan-fiction so please be nice!
