The characters and setting do not belong to me. They belong to the wonderful J.K Rowling and Rick Riordan.

Hi! This is my first post, and I know that this topic is done a lot, so this might not be new for you. But please review! This is my first chapter and post ever, So I hope you enjoy!

oh, and Another thing, I haven't actually read all the Harry Potter books, only up to book four. So I might make a few mistakes on Harry's side of things, but I'll try my best.

Chapter #1 Percy's POV

Chiron, Annabeth, Leo, Nico and I weaved our way through the crowded London train station. No one paid any attention to us, except for maybe a hint of annoyance at Chiron's wheelchair. People had to avoid bumping into it, which made a sort of breaker against the current of people.

We each were each carrying a trunk/ suitcase thing, filled with a bunch of our important stuff, and demigod necessities. We all had ambrosia and nectar, as well as a few drachma, just in case. Chiron had given us wands, that channeled our powers into stuff more like what the wizards did.

Half of my suitcase was filled with blue cookies that my mom made for the journey. I also had riptide in my pocket, as always. I know that Annabeth had brought Daedalus's laptop, and that Leo's suitcase was actually Festus. Nico...I had no idea what that dude had brought, and I didn't want to know.

" So which train takes us to Hogwarts?" Leo bounced up and down, he seemed to be everywhere at once, filled with nervous energy. Chiron whipped his head to face him.

"Sshh! Don't say the name so loud, it supposed to be hidden, like Camp!" We all had been briefed by Chiron in the Big House a week before. With the aftershock of the war against Gaea, A lot of monsters had escaped Tartarus, and have started another uprising. They almost seemed to follow us wherever we went.

Chiron had told us that he was in contact with Some guy named Dumbledore, and he had a school for people like us in Scotland. He had agreed to take us in for a while, until it was safe to return to America. He also told us that if we saw any monsters, don't hesitate to kill them, because increasingly strange things have happening at the school, and Keeping them at bay would be like a mini quest. As if I haven't had enough of those.

" Right, sorry Chiron." Leo said, quieter now. We crossed a path, fighting against people on their way to work, or some other business. We made our way to a platform, and we stood next to a brick wall. It was quieter here, with less people.

"Is this the platform?" I asked, skeptical, because it was so… well, normal. Normally, there would be some little symbol indicating an important place, or a bunch of monsters hanging around.

"No, Dumbledore gave me instructions, and said that you have to run straight through that wall."

"What?" Annabeth and Nico both asked. Leo just stopped hopping from foot to foot.

"Are you crazy?" She exclaimed, "That's a solid wall! Its molecular density is way too high for us to pass through! Even Seaweed Brain knows that." she looked at me, silently asking me to back her up. I looked at her, and shrugged. If this was for wizards, it kinda made sense

"Nope, just run at it, and you'll be on platform 9 ¾. It's a special type of magic." Chiron replied, totally unfazed. We all exchanged glances. "Just trust me on this. Oh, and before you leave, I will need to give you a few details." Nico snorted. I seconded on that one. We were about to run into a wall, catch a train to a magical school for wizards, and just act like we belong there. Great. I can totally do that.

"-and you just need to lay low, Dumbledore recommended you stick around a boy your age called Harry Potter. You will also need to secretly protect him against anything that might come his way. And that's it! Good luck!" he said cheerfully. Deep down I could tell he was worrying. We all are. We said our goodbyes, and turned our attention to the wall. Annabeth and I glanced at each other.

" On three. One... Two… THREE!" We both ran, and the brick wall turned to a bustling platform, filled with some people in weird robes, and packed with trunks and carts, and owls in cages.

"Whoa." Annabeth breathed. I agreed. Behind us, I heard Leo scream " Mr. McShizzle comin' in hot!" Before Annabeth and I could move out of the way, Leo crashed into us. He got up, and we scrambled out of the way before Nico could barrel into us too. He came hurtling through the wall, stumbled, and fell. Leo snickered, before being shushed by a whistle.

While everyone else seemed to be busy doing something, we sort of just stood there in a group, looking around, with no idea what to do.

A very large man came up to us. He had a big coat, and a great big beard that seemed to eat up his face. I might have almost mistaken him for a monster, or maybe a titan of some sort in disguise-he reminded me of Bob. He loomed over us, and in a gruff voice, said,

"Are you those 'Merican exchange students?" he spoke with an accent I couldn't place. He seemed kind, despite his appearance. I looked at my friends.

" Uh, yes?" I said, unsure of what was going to happen. Leo fidgeted with a button on his shirt. If he didn't have a sufficient amount of bits and pieces to play with, he would make do with what he had, and that wasn't always a good thing.

"Ah yes, Dumbledore told me you were arriving. The name's Hagrid."

"Nice to meet you Hagrid, do you know where we have to go?" Annabeth had to tilt her head up a long way to look at his face. He chuckled.

" That's me job" He smiled and his beard shifted with his face. " Just get on that train, I've told three students to look after you, so they'll save some seats in a carriage for you. Do you have robes? He eyed us. Oops. did we need a uniform? Luckily, Annabeth took charge.

" I've got them." she said casually, as if carrying a bunch of your friend's robes are normal. I saw that Nico and Leo also sagged with a bit of relief. Gods, we're lucky Annabeth is here. Hagrid beckoned for us to follow him, and we made our way to the other end of the station, where we boarded a carriage. We stepped into a carpeted hallway. Hagrid showed us to an empty cabin, and told us that the other kids will be here soon. We said our goodbyes again, and Hagrid shut the door. Leaving us to our silence.

" oookay. " Nico said, breaking the silence.

" I think this will be kind of fun! I mean, It's not everyday we get to study new magic." I could tell she was trying to lighten the mood. You go Annabeth! I silently cheered.

"What do you think this wizard school will be like? I wonder if they do training like we do." Leo said, changing the subject. I considered.

"Hopefully stuff won't be too hard." I said. " I mean, we don't know the first thing about wizarding. Maybe it's all just Bibbity, bobbity, boo!" I said, mimicking the waving of a wand in the air. All my friends chuckled, and as they did, three kids, about our age, entered. One of the boys had red hair, and the other round glasses and a funny looking scar on his forehead.. The third was a frizzy haired girl. She stepped to the front of the trio.

" for your information, we don't just wave wands around, saying random Disney movie words, there's a lot of skill that goes into wizarding."

She looked me in the eye, and the look she gave me reminded me of what Annabeth often did. It was weird. I wondered if she and Annabeth would end up at each other's throats, or best friends.

"Hermione, Hermione Granger." She said, and held out her hand. I shook it, and so did Annabeth. "This is Harry Potter, and Ron Weasley." They waited, almost as if expecting some sort of reaction. When they didn't get it, They just glanced at Harry and shrugged. Leo stood up.

" I'm Leo, That's Percy and Annabeth, and this is Nico." He grandly gestured to Nico, in that silly, joking way of his. We made space for them, and all sat down.

"So what brings you here in the middle of a semester? Most kids arrive at the beginning of the year." Ron, the red haired one leaned forward, and looked at me. I shrugged.

"We're from America, and we came because…" I trailed off, unsure of what story to go with, Chiron had never told us what to say.

"We have come to study magic. Strange stuff has been happening to us, and it is safest here." Annabeth continued on confidently. Her story was part of the truth anyways. We settled down as The wizards began to tell us about the school…

Harry's POV

I didn't know what to think of these Americans. They seemed normal enough, except for the one called Nico, he scared me a bit. After a while of Hermione describing the school and classes, she stopped. And sat up straight.

"Why are you all so fidgety?" She asked. The dark haired one who hadn't said anything before replied with

"We all have ADHD." The others nodded in agreement. As Hermione droned on, Percy interrupted, which I silently thanked him for.

"Anyone hungry?" He asked, opening his trunk. Why was their stuff still with them? Shouldn't they have put it in the storage space? Oh well, I thought, doesn't matter too much.

He pulled out a massive Tupperware container, and when he opened it, it overflowed with blue cookies. He passed them around, and Ron and I took one each, thanking him. Hermione however, didn't.

They were amazing. I sighed, not realising how hungry I was. It had been a long trip from Ron's house to the station, and we had met Hermione here, so she had probably eaten.

" Mmmmm!" Ron said through a mouth of biscuit. "Thith ith amathing!" I agreed with him. They seemed as if they were fresh out of the oven.

"Did you make them?" I asked, curious to know who was behind these amazing cookies. Percy chuckled.

" My mom made them. I'm glad they were put to use though, otherwise I'd be lugging them around all the time!" I found it funny how he said mom instead of mum. Hermione finally gave in and took one when Percy passed them around a second time. She smiled, and nodded, her mouth as full as Ron's. whe n she had finished her mouthful, she spoke up again.

"Why blue?" She asked.

"Just a family joke that kinda turned into a tradition."

After a while, when our hunger had been accounted for, we went silent, and each slipped into our own thoughts. Leo I think his name was- found some gears and springs in his pocket, and started fiddling with them. Who keeps gears in their pockets?

Time passed, and Hermione started reading some textbook. Hagrid, who was on the train, was knocking on doors, telling everyone to get changed into their robes.

" Hi Harry! How was yer break?"

"Good thanks." I replied politely. He smiled at Ron and Hermione, before continuing on. Annabeth went to her trunk, and pulled out their sets of robes.

"Here you go." She handed them out, but stopped when giving Leo one. " Don't burn it" Annabeth whispered.

"You can rest in peace, Mr. Leo McShizzle won't burn anything today." He gave a mocking salute to Annabeth, and she rolled her eyes. While her trunk was open, I noticed some honeycomb looking things tied in a bundle of paper. I wondered what they were. I also got a glimpse of metal, and it reflected in the light. She noticed me looking, and quickly shut it, giving me a warm smile instead.

"Hey man, where do we change?" Percy turned to me, his robe in a bundle in his hands.

"Follow me." I led him, Leo, and Nico to the bathroom, where we stood in line with the other people that needed to change.

When we finally arrived back to our cabin, I found Annabeth and Hermione changed, and they were both scowling at each other. Uh oh, Not good. I wonder what had happened. The group of four looked very different in their wizard robes. They didn't quite fit on them like they did with all of the other students. I wasn't sure what to think, it was such a minor change, but it seemed important. What are they hiding? And who are they really? I was shaken out of my thoughts by Ron.

" A word with you mate." He tugged me to the corridor. I stepped out with him. It was empty.

"What's up?" I asked, curious about what was so important.

" Those Americans are really weird." He said plainly, glancing over my shoulder and into the compartment.

" you came out here to tell me that?" he shrugged. "Of course they're weird." Ron gave me a look.

" I know, but I think that their hiding something, or their not really who they say they are." I nodded in agreement

"I'm pretty sure I saw knife in the blonde one's trunk." Ron looked at me, alarmed. "never mind, we'll sort it out when we've settled back into Hogwarts."

We went back into the compartment, and made small talk with the Americans. Annabeth wouldn't talk to Hermione, and I didn't even want to know what went on when we turned our backs.

As we got closer, The four couldn't keep their faces away from the window.

"This is very new to us. We've never been to England," Percy explained. "Have you ever been to America?" he asked. I shook my head, so did Hermione and Ron. Annabeth gasped, and ran to the window. She looked out at Hogwarts, completely fascinated by it. Percy laughed. Leo looked at us, smiling. He explained

" It's all I want to do when I grow up." She admitted sheepishly. " Your school has some of the finest I've ever seen. I can't wait to see what's inside." The train slowed to a stop, and the Americans picked up their stuff, ready to go.

" follow me!" I said

" Try not to get lost." Hermione added. I led them off the train, from there, we began to make our way to the school. We hung back, so we were at the end of the group. I was surprised, things weren't going too bad, but of course, that luck never stays.

"Oi Potter!" Ugh, I knew that voice. Malfoy. He jogged up to us. His blond slicked back hair catching the afternoon light. " who are these?" He asked, regarding the Americans. " I'm Malfoy, Draco Malfoy."

" I'm Leo, Leo Valdez" Leo held out his hand, a smirk on his face, he was mocking Malfoy. That doesn't happen often. Malfoy looked disgusted now.

"Where are you from? And you should be hanging out with someone like me, not these losers." Percy chuckled,

"You sure you aren't getting it wrong? It should be the other way around." He smiled Malfoy scoffed, and I could tell he was searching for a retort, but couldn't find one. I mena, Percy's wasn't that good either, but the fact that he stood up for himself to Malfoy, on his first day said something.

" wait till my father hears about this." He mumbled. The Americans exchanged a glance, they were holding a laughing fit in, but I wasn't sure what could be so funny. Oh well, I sighed.

"Come on, Dumbledore wants to see us." I said. And led them into Hogwarts.
