Hello! This is my first ever FanFiction! So I decided to go big or go home! If you don't like, just review and say THIS COMPLETELY SUCKS! or if you're the designated word police just type in WORD POLICE all big in your review. Then I'll blame my friends for not proofreading well enough. Nah! I'm just joking. Please! Read this all the time! If you don't, you might miss out on something BIG. Like a hint on who's gonna die. Sorry if the paragraphis look weird. Google Docs doesn't translate well to FanFic. Comment different ship names if you want more of that. Just, if you think there could be more improvement, comment... or whatver you do on FanFiction. All of the info in here is based off of the most recent stuff posted on the website . Like Ilvermorny (I think that's how you spell it) and all of this somehow takes place after Blood of Olympus but before the Battle of Hogwarts. Time travel stuff may have ahd to do with this. This takes place in Harry's 5th year. I wish you well on your journey!

Disclaimer: I do not own Percy Jackson or Harry Potter. Thank the amazing authors JK Rowling and Rickriordan for these wonderful characters! I think this is how disclaimers work. Don't blame me! I'm a noob!

Let's begin!

Chapter 1

Percy

I was snoozing on the beach, Annabeth in my arms, when I heard the conch horn signaling that it was time for dinner. I lifted my head up and stared at Annabeth. She looks so peaceful. I planted a kiss on her forehead and gently nudged her awake.

"Hey, Annie. It's time for dinner" I started poking her in her stomach. Her eyes burst open and she burst into a fit of laughter.

"Hahahaha! HEY! Stop doing that, Seaweed Brain!" She started poking me, which caused both of us to start laughing again. We promptly got into a big poke war on the beach. Yes, life was bliss after the Giant War. This was our last year at Camp Half Blood before we go to New Rome to go to college. While I was zoning out, Annabeth pinned me down. I was quickly shaken out of my daze and stared into her stormy grey eyes. We held our gaze for a moment before I heard the falling of footsteps behind me.

"Come on, lovebirds. Its dinner time!" Came the voice of Jason. I took a quick look back at Annabeth before replying.

"Yeah, fine. We're coming, Sparky". Annabeth got off of me and dusted herself off. The golden sun in her hair made it look like thin strands of gold. She caught me staring at her and took the opportunity to steal a quick kiss.

"Come on, Percy! We're gonna be late!" She started tugging me in the direction of the mess hall, before releasing me, leaving me to stand on the dunes with Jason.

"Hey, only Piper gets to call me Sparky", he complained.

"Not anymore!" I teasingly said. I was making my way to the mess hall, when Jason grabbed my arm.

"What's up, man?" I asked, wondering why he was doing this. He quickly released my arm, a hint of blush on his cheeks…

"Uh, Chiron wants to see us after dinner" he said, almost mumbling it. I stared at him. By 'we' he means all of us, right? Jason knows what'll happen if Annabeth doesn't come. Even if the world was to be destroyed in the next 48 hours 'cause Zeus couldn't keep it in his pants, I wouldn't budge. I will NOT do anything without Annie at my side. But I could see it all so clearly displayed on Jason's face. Annabeth wouldn't be coming with us on whatever was happening.

"No, NO. Jason, you know, even Chiron knows I won't go anywhere without Annabeth" I quickly cut back. Jason looked a bit, well, un-Jason-y. Like…

"LEO! I TOLD YOU NOT TO MAKE JASON ROBOTS!" Leo's been working on these "demigod friendly" AI robots that could go on 'important' missions when the real ones are not available. The problem is, whenever Leo makes one of Jason, it's like a shoujo anime character. A tiny crackle emitted from a small speaker in the nostril.

"Dang it, Perce! Always so good at spotting the difference!" came the cocky voice of Leo in who-knows-where with Calypso. His parting gift to us was an army of Jason-bots.

"But seriously, get to dinner, man. And Chiron does want to see you, without Annie". I clenched my fists. I glared at the Big House on the hills. Then I turned my attention to the mess hall. Sounds of rapture were emitting from the hall. Man- Annie's been rubbing off on me. The Jason-bot cackled back to life.

"So, man, you gonna accept?" Leo asked. I stared back out at the sea. I thought about what Annabeth would want me to do. I would guess that she would want me to do this, even if she couldn't go.

"Yeah Leo. I'll do it".

"Great! Go meet up with us at the Big House after dinner. But seriously, bro. Go eat. Your stomach has been growling for-ever". I walked over to behind the robot and smashed down on the power-off button.

"Thanks man". I walked off the beach, with 30 minutes left of dinner.

After a rushed dinner of delicious BBQ and breaking the news to Annabeth, I felt about done. As I made my way towards the Big House, I wondered what our quest was going to be this time. As I was thinking about this, I missed the turn to go up to the porch and ended up in a small space. I recalled some of the Aphrodite bunch talking about it. They called it, uh… Makeout… Makeout something or rather. Again, because of ADHD I was prone to zoning out, not noticing the terrified shrieks of two particular male campers.

"GAH! P-p-PERCY?! Wh-what are you doing here?!" came the terrified voice of Nico Di Angelo.

"Wait, what? Nico? WILL?! What are you guys doing HERE?! Were you- nevermind" I said quickly, avoiding their terrified eyes.

"I-i-i was going to the B-big House for the q-quest", I stuttered. I backed out of the clearing. I could sense their presence behind me. Following me. They probably were here for the meeting, too. They just got a little… sidetracked. I made my way to the porch where Jason and Leo were already waiting. Chiron was there as well as Argus. Chiron was in wheelchair form and Argus was standing in the corner of the porch.

"Ah! Children! Nico, Will, Percy, welcome!" Chiron said in a cheery voice, which obviously indicated he was hiding something.

"Come on Chiron, get to the chase" Will droned, a bit lazy and bored. I couldn't help but to glance back at Nico and Will, holding hands. Lucky ducks. To bad it's an all boys mission. But, why's Leo here? Doesn't he have stuff to do wi-

"Look, Chiron, see, I, uh, can't go on this quest…" Leo trailed off, but Chiron waved him off.

"Alas, Leo, you were never going on this quest. You were just here to provide us with simple… communication devices that cannot be detected by monsters or ruined by magic", Chiron tentatively said, as if defending himself from Leo's reply. Instead, Leo looked relieved and pulled out 4 small devices from his toolbelt.

"Man, I was waiting for this day. BAM! Four comm devices I like to call Valdezian Comms. These little babies hack on to any satellite feed and, if none are available, can create it's own network. Pretty neat, right?" Leo went on with this big thing about everlasting battery life and whatnot. He finally passed them out.

"Just- don't use them too much. As little as humanly possible is to much strain on them. Use them wisely". Leo said in an Obi-Wan- Kenobi voice and went back to whatever he was Chiron spoke up.

"Please, follow me". Chiron led us to the rec room, where the most serious of meetings are held.

"Now, this may be a bit difficult to explain, but being demigods, you should be pretty adaptable to change", Chiron addressed the rest of us, which was Nico, Will, Jason, and I. "Long ago, Hecate had four children who excelled in their magicks. These four were named Godric Gryffindor, Rowena Ravenclaw, Helga Hufflepuff, and Salazar Slytherin. These four created a school for witchcraft and wizardry called Hogwarts-" He was cut off by the stifling of laughter.

"Hogwarts?" Jason gasped, failing to hold in laughter. "I mean, I get the wizards, but a school called Hogwarts?!" Chiron glared at us, but a smile played on his lips.

"Yes, Hogwarts. Now, a dark wizard named Voldemort-" Everyone burst out laughing. The baddie of the wizarding world was named Voldemort?! HAHA! Chiron couldn't help to let out a chuckle or two, before returning to explaining. Apparently, a boy named Harry Potter was a baby when Voldemort attacked him and failed to kill him. He failed, destroying his physical form. Now, Voldemort has a physical form again and is terrorizing the world. The ministry doesn't believe this and is not taking any protective measures whatsoever.

"So, let me get this straight", I started. "We have to go to Hogwarts to protect that kid named Harry Potter. That's all?" Chiron considered it and added something.

"Remember, make friends with Harry's friends and Harry. The only thing is, there are a couple of demigods undercover at the school". This started a small discussion between us, trying to figure out the demigods.

"Now, you will be leaving for England tomorrow morning. Don't worry, you will be flying by pegasus. You will be staying with Mr. Potter and friends at the Burrow until the start of the school year. My good friend Albus Dumbledore, is the headmaster at the school. Um… Oh! Yes! Tomorrow Hecate will bless you with the ability to use magic. You will also be in the same year as Mr. Potter, which is the 5th year at the school. Now pack up and get some sleep". Chiron sent us back to our cabins. Jason went in search of Piper, Will and Nico went to the Hades cabin, Will giving Nico random kisses on the cheek, and I went straight to the Athena cabin, where Annabeth was sitting outside of, staring at the stars with an architect book besides her. I lay down next to hear and curl her hair around my finger. She turned her head toward me and stared into my eyes.

"Hey, Wise Girl".

"Seaweed Brain". She laughed and I pulled her in for a kiss.

"Sorry I have to go. Chiron said it would be for about a year. But I promise to come back for all the breaks. Chiron also said there were some demigods undercover there. I don't really know who they are yet, but I can't wait to find out if it's an old friend. Wish you could-" She cut me off with a wave of her hand, like she didn't care.

"Percy, just write to me and visit on breaks. As long as you constantly keep in touch, I'm fine".

"But what-"

"I'm fine, Seaweed Brain! I've got everyone else who still are at camp to take care of me! Just let it go!" She pulled me in for one more kiss before she rested her head on my chest. We were just lying there, without a care, until the cleaning harpies started showing up. I told Annabeth to go back into the cabin. She stared at me and gave me a short kiss.

"It'll be fine, Percy! It's only school!" Annabeth said. "And even though I'm overly jealous, you'll come back for all the breaks, right?" Man, she's hot- the Artemis cabin nearby had a brilliant glow, like the moon, which bathed Annabeth's figure. She was saying something, but I was just distracted and tired to figure out what she was saying, until she grabbed my arm and started sprinting to the Poseidon cabin.

"Hey, wait, what are you doing!" I called out. She turned back and looked at me like an idiot.

"The harpies were going to find you standing outside like an idiot!" she hissed back. Oh, yeah. The harpies. When we reached the Poseidon cabin, she gave me another kiss and pushed me inside. She was sprinting back to the Athena cabin, when I finally closed the door. I sighed and looked at the cabin. It was a bit messed up. Random clothes strewn around on the floor. I bent down and picked up a bag near my feet. I looked back at the saltwater spring in the corner of my room. It had a soft green glow coming from it.

"Better make a call". I walked over to the fountain and fished for the drachma in the water and tossed it in. The mist showed me a forge, with lots of burly cyclopes. The one directly in front of the mist on the other side was none other than Tyson, my half-brother.

"Hey, Tyson!" I called out. Tyson looked around him and then looked up.

"Brother!" he half shouted cheerfully. He came in for a bear-hug before remembering it was an Iris Message.

"Listen, Tyson. I'm going on another quest and I might not be able to talk to you for a while. Uh, listen, just tell dad, uh-" I was thinking of something to tell dad, but Tyson cut me off.

"No, brother, daddy knows about the quest. Just, don't die!" Tyson waved a hand and the message went down. I walked around and started picking up clothes and important demigod stuff for the quest. 1 year, excluding holiday breaks. What to pack. I tossed everything into the bag and fell face first into my bed. I just hoped that any and all dreams tonight would be something to get my hopes up about this quest.

-Line Skip-

It was 6 AM when the clip-clop of hooves woke me. I was sleeping in last night's shirt and jeans.

"Coming out in a bit!" I called out to Chiron. I took a quick glance back at the fountain and decided to call mom. I scrounged for a drachma on the floor and came up to the fountain.

"O, Iris, please accept my offering!" I grandly made a dramatic show of tossing in the drachma. "Please show me Sally Jackson!" The mist shimmered and came upon Sally and Paul, watching TV. Mom looked up and saw me there.

"Oh, hey Percy! I already know about the quest, Annabeth told me last night. When are you leaving?"

"Today, mom. I just came, sorry, called, to say bye. Bye, mom! Paul!" I waved back at them and cut the connection. I sighed and grabbed my bag. I walked out to the cool morning and took a stroll to Half-Blood Hill, where Jason, Chiron and four pegasi were waiting.

"Sorry I'm a bit late", I called to them. A gathering of mist came and Hecate appeared with four stick-thingies. In the shadow of a tree, Nico appeared with Will.

"Sorry we're late", apologized Will. Nico just looked down, blushing furiously. I was about to ask, when Hecate spoke up.

"Hello, children. As you all should know, I am Hecate, goddess of Magic". As she was speaking, she glared at me. Of course she glares at me. Why? I don't know. Hecate continued with her speech.

"As you know, you will be going to a school called Hogwarts, which was created by my four most talented and powerful children, to protect Harry Potter, the boy who defeated the dark wizard, Voldemort." She took a turn to glare at all of us, who were trying to hold in laughter. She continued, apparently a bit miffed that we would laugh at some serious matters.

"I will grant you with the ability to use magic with these wands", she gestured to the wands she held in her hand.

"Jason, your wand will be made of redwood with a venti core". She handed Jason a slightly red wand.

"Please tell me the storm spirit in here isn't Dylan. I don't want to be using him as a wand core", Jason looked frightened at the thought of that, especially after he learned he was breathing in Dylan air when he went to meet the goddess/ my sister Kym.

"Don't worry, it isn't the venti you call Dylan", Hecate assured Jason. She then proceeded to hand everyone else wands.

"Nico, your wand is asphodel and thestral hair core. Will your wand is eucalyptus and red cattle tail core". Nico looked a bit murderous when he got his wand. Probably because of the asphodel, the thestral, or maybe both. What's a thestral anyway? Will just looked plain annoyed.

"Father's cows will help me use magic. Hooray". Hecate finally turned to me and handed me a blueish wand with a red base and Ancient Greek spells running up and down the length of it.

"Perseus, your wand is coral and sea serpent heartstring core. But be warned, your wand is the most dangerous wand ever created". Hecate turned to all of us and said a few choice words in Ancient Greek. All I could decipher was the words magic, grant, and something that sounded a lot like Arnold. I felt tonnes of magical knowledge flowing into my brain. I had the urge to take my wand and yell abracadabra.

"Now, children, do not tell ANYONE, including Mr. Potter and friends that you are demigods. Only Dumbledore and a few select teachers know about your true identity. Know, remember, there are a few undercover demigods-" Chiron was cut off by Jason.

"Who are they, Chiron?" he asked impatiently. Chiron thought about it for a moment.

"Their names at school are Draco Malfoy and Luna Lovegood", Chiron said. Will was happy, of course, to hear this.

"The Malecint twins? Yeah! I haven't seen them in forever!" Draco and Luna Malecint were Apollo's kin, so obviously Will was happy. He also got to show off to Draco that he was senior counselor of the Apollo cabin. I remembered that I used to have the best duels with Draco after Luke left. Luna will be devastated. Luke was her crush. She probably heard about it, but just to be sure, I was going to tell her.

"Now, you guys will be in the 5th year, with Mr. Potter. You will train in a discreet clearing in the forest. Remember, you will reveal your identities ONLY when you have the okay from Dumbledore and I. Now, off with you! Save the world again!" Chiron waved his hand.

"TO ENGLAND!" I shouted as I mounted Blackjack. A chorus of huzzahs! came from the others as the pegasi took off.

So! How was that? Sorry, I'm just not good at names. So, basically just keep on reading! The next chapter is going to be in the Burrow. Now, I know that in Harry's 5th year he has a hearing and is staying in No. 12 Grimwald (or whatever. Not stressing spelling in Author's Notes) Place. Uh, the italics could be a bit confusing, but those are thoughts that are related to telling th story, just because it's in 1st person, it might be confusing. Those are just thoughts that the person telling their POV has in those moments. Makes sense? Great! I'll try to update as fast as I can. See you next chapter!
