Hey guys! I woke up this morning thinking, "Maybe I should write a fanfic, and actually finish it this time!" I know, crazy, right? And then I saw all these crossovers between PJO and HP and I didn't really like any of them, because I'm nitpicky...so I decided I'll write my own! I know I'm really bad at updating my stories, so I'll try my best this time…but like a better best(Percabeth, some background Solangelo even though it's my otp, but it probably won't be until the sequel if there is one)

Oh, and by the way, if you're reading this and thinking, "Uh, you literally don't have any other fics," Well I have another account called MistyVeil, and I got a new one because why not?

Disclaimer: I don't own Harry Potter (duh!) or Percy Jackson/Heroes of Olympus (duh!). So yeah.

Also they never mentioned (or maybe they did and I wasn't paying attention) where the Golden Trio went to change into their robes? Based on the text I guess they just pulled them on over their Muggle clothes? But whatever.

ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

Chapter 1: Percy's POV

I woke up with a pounding in my skull.

Actually, I should rephrase that. I woke up with a pounding on my skull, because my loving girlfriend was hitting me on the head, repeatedly, with her hand.

"Ow," I complained sleepily. "What was that for?"

Annabeth smiled at me exasperatedly, withdrawing her hand, and I see she's already changed into her robes. "We're here, Seaweed Brain! Hogwarts School of Witchcraft and Wizardry."

I pushed myself up on my elbows to look out the window of the train and saw that she was right (honestly, I didn't even know why I was surprised anymore). Instead of the rolling green hills and the occasional sheep we'd passed so far, there was an enormous castle that looked like it was plucked right out of a fairy tale. There was a lake out in the front and the reflection from the castle's bright windows made it look like an eerie mirror. It was still far in the distance, but I could already tell it was impressive, and would probably be even more so up close.

Wow, I was beginning to sound like a poet.

I reflexively checked my pocket for Riptide, even though I knew it would be there. "Woah," I said, for lack of a better word.

"I know, right? The architectural—I mean—this place is beautiful, isn't it!" Annabeth got the dreamy look in her eyes that she always did when she talked about architecture. She cleared her throat. "You should probably get your robes on, Percy. And make sure you hide your Camp Half-Blood T shirt in your suitcase. We don't want to draw too much attention," she reminded me.

I should probably back up right about now. After we finished our first year at New Rome University, we got an urgent Iris-Message from Chiron back at camp, saying we would have to go on a quest once again.

As you can imagine, we weren't thrilled.

-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-

Two Months Ago, New Rome

Annabeth and I were walking down the streets of New Rome, having finished our last official class of the year (excluding pegasus riding and sword fighting, which we were going to help teach later in the week).

"How do you feel, Wise Girl? Enlightened? Enriched? En—" Before I could come up with another word that started with en, she interrupted me.

"I feel nervous," she told me. "I mean, I know we finished this school year okay, but what about next year, or the year after that? I don't exactly have much experience in the normal school category, you know, considering I spent most of my life in a camp where the activities weren't exactly school-oriented!" Annabeth was walking quickly, anxiously motioning with her hands as she spoke. Her curly blond hair whipped around her head in a frenzy like it was anxious too.

"We'll be fine," I assured her, wrapping my arms around her waist to stop her forward movement. She looked at me with her steel-gray eyes that were darting back and forth worriedly. I almost laughed; we'd survived literal hell together, but it was college that freaked her out. "Besides, this isn't exactly a normal college." I grinned.

Annabeth did a quick look over New Rome, where Lares milled around everywhere, and every other person was carrying a spear. She huffed. "I know, but—these people have lives, Percy. They grow up, and grow old and—" I knew what she was going to say. At Camp Half-Blood, even within the magical borders, people weren't expected to live past their teens. Here, on the other hand, people only had to serve in the legion for ten years, and then they could move on. It was an entirely different culture.

I was about to reply when I heard a voice behind me.

"Er, is this a bad time?" I turned around to see the watery image of an Iris-Message hovering in the air. Inside was a boy, probably twelve or thirteen, wearing an orange Camp Half-Blood T shirt and looking very awkward. Based on the bronze gadget he was fidgeting in his hands, I guessed he was a newly claimed son of Hephaestus.

I schooled my expression to look calm, and when I looked, I saw Annabeth had done the same. I realized what it had probably looked like to him, with my arms around Annabeth's waist, faces close together and quickly let go.

"Uh, no it's fine," I told him, even though it kind of wasn't.

"Okay, um, so...Chiron said he needed you to come back here...like, now, he said he received a...message?" said the boy, wringing his hands together like he knew the news wouldn't be received well. He had the same awed look in his eyes most of the new half-bloods seemed to get whenever they saw me or Annabeth.

"Can it wait?" Annabeth asked irritably. Her eyes softened, "Sorry. I mean, we just got off school. And we've already done plenty of quests," her voice sounded strained, and I couldn't blame her. Not that we didn't care about whatever was wrong at camp, but after defeating Kronos, and Gaea, and going through Tartarus, I thought we, and the rest of the seven, deserved a longer break than one year.

The son of Hephaestus shook his head. "Sorry, but Chiron said it's an emergency."

I sighed. "Okay, we'll be there soon; you better hang up before you waste any more drachmas."

The boy flushed red, and I felt kind of bad because I hadn't meant it in a mean way, but he ended the Iris-Message before I could say anything.

I turned back to Annabeth, who was already staring at me, looking dejected. "Well, there goes our summer vacation," she said glumly.

"Hey," I tried to reassure her. "It could just be a minor issue, and then we can come back here and enjoy our summer," I said, but I couldn't even convince myself, not to mention Annabeth.

Annabeth's face hardened into a determined mask; it was the same look she made whenever she was going into battle. "Alright then," she said. "I guess we're going back to New York."

a couple days later

Once we finally arrived at Camp Half-Blood, Annabeth was in a much better mood. She was humming as we approached the magical borders on Half-Blood Hill. Her gray eyes looked less like dull metal and more like moonlight, and I thought she looked as beautiful as ever (read: that won't change).

We walked through the camp to the Big House, where Dionysus was playing Solitaire (since when?) and sipping a can of Diet Coke on the porch.

"Ah, Parker Janson, it's nice to see you!" he exclaimed as we approached. Surprisingly, he was smiling. "And Abigail Connors!" He looked back at his game of Solitaire for a moment and his smile melted. I guessed the game wasn't going so well."If you're looking for Chiron, by the way, he's inside," the wine god told us, back to his usual unenthusiastic demeanor. He was still frowning at his cards as he waved us in.

The inside of the Big House looked much the same as it always did, except for the leopard head on the wall, Seymour, who apparently was a new addition. Chiron sat in his wheelchair with the fake feet in front of a table, looking tired and drawn.

"Chiron?" Annabeth said uncertainly, since Chiron's eyes seemed to be focused on something far away.

The centaur blinked. "Annabeth!" he said. "And Percy, oh, thank the gods."

I frowned. "What's up?" I asked. "It's not another prophecy, is it?" I was mostly joking, but to be honest, if there actually was another prophecy, I was going to flip out.

Chiron smiled. "No, of course not. However, I do need you two and some others to go on a quest," At our tense expressions, he explained, "Nothing too dangerous, I promise. It's...a different sort of quest; more like collecting information. You will have a few months to prepare."

Of course, Annabeth was the one asking the important questions. "If it's not world-ending or anything...why does it need to be us?" she asked.

Chiron's smile turned into more of a grimace. "I'll let you see for yourself," he said ominously. He started muttering under his breath, "...message...she...where…" I couldn't make out the words entirely, but I wondered who 'she' was.

Annabeth tugged on my arm. "Percy," she whispered. "What if it's Hera again?" She clenched her fists. "Ugh, if it is, I'm going to kill her," I nodded, deciding not to mention that Hera was an immortal goddess. If anyone could manage to harm her, though, it was Annabeth. I might have a few choice words with Hera myself, given the chance.

"Here it is, I received it...or rather, one of the campers found it this morning," said Chiron, who was holding a piece of parchment up in the air. It looked like one of those ones from movies, that are all browned and hold secret messages in them.

Annabeth stepped forward to take it, and put it on Chiron's desk in front of us so we could both read it.

Dear Mr. Jackson and Ms. Chase,

We are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment. Term begins on September 1st., We await your owl by no later than July 31.

Yours sincerely,

Minerva McGonagall (Deputy Headmistress)

PS

We are aware that you two students will be entering into the 6th year of Hogwarts as transfers from Ilvermorny, from the house Thunderbird. Therefore, you will immediately be sorted into Gryffindor house here at Hogwarts. I have included a list of the charms and spells you will be expected to know once you arrive. While I know the standards at Ilvermorny are similar to those here, it will be best if you are prepared for a contradiction.

Below that was a passage in ancient Greek. I could see the Mist (I'd been getting lessons from a Lar at Camp Jupiter) shimmering around it, which probably meant a regular mortal wouldn't have been able to see it. This is your crossroads, my heroes, it read.

Hecate.

"Wizards?" I choked out. There was such an overload of information in my brain right now, I felt like a balloon about to burst. There were other words swimming around in my mind too. Hogwarts? Thunderbird? Witchcraft and Wizardry?

The weirdest thing was, Chiron's face was entirely serious. I kept waiting for him to say, "Ha! I fooled you! You can go back to your summer vacation now! See ya later!" but that totally wasn't his style.

"Yes, Percy, wizards. And witches. Remember when I said there were other parthenons out there? This is the same way, but instead of gods and goddesses, these wizards and witches have been living in secret for a very long time. I suppose you could call them relatives of Hecate, if that makes it easier," Chiron explained patiently. My brain felt the same way it did when I'd learned there was someone trying to resurrect the Ptolemaic gods. This was probably how a mortal might feel if the Mist suddenly disappeared.

Annabeth, on the other hand, looked much more composed. A little shell-shocked, but not nearly as surprised as I would have thought. "That makes...sense," she said a little breathlessly. "I mean, I read about a distant branch of Hecate's family that developed away from the rest of Western Civilization and the Greek gods, but to have kept their magic? Wow. I guess it's totally plausible that they have an entire civilization now, since they branched out so long ago," Annabeth finished. She looked in awe, the same way she did when she was looking at all the buildings in cities that turned my brain into so much useless mush.

"So...you want us to go to this wizard school?" I asked Chiron, my head still spinning a little. "To do what?"

"I can only imagine," Chiron told us haltingly, "that it will become clear once you get there."

"So what you're saying is we don't have a choice," summarized Annabeth. "And you can't tell us anything, because Hecate told you," Annabeth sounded a little hurt. Chiron rarely kept anything from her; she had even known about the first Great Prophecy.

Chiron sighed. "I would tell you if I could, believe me."

For the next couple of weeks, we prepared for our journey to Hogwarts School of Witchcraft and Wizardry, which apparently was in London. Our quest was, essentially, to take a train called the Hogwarts Express (original much?), which was in an invisible platform at a train station (?) to a school where young wizards and witches learned magic. Our cover story was that we were transfer students from Ilvermorny, which was another wizarding school in Massachusetts. When I asked Chiron why we didn't just pretend to be students there, he muttered something about "...mixing...pantheons...not good…". I decided not to ask, in case I would go insane from the information or something. We would attend classes there as sixth year students, maybe pick up some basics in magic along the way, and (hopefully) figure out whatever crossroads/purpose Hecate had in mind. All without starting a war.

Again.

I got more and more wary the more I learned, but Annabeth was the opposite. The more Chiron told us about the society, rules, and creatures in the 'wizarding world', the more excited she got. By the time we were ready to leave, she was practically buzzing with excitement.

Me, personally? I just wished the gods would leave us alone for.

One.

Stupid.

Second.

-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-

"You should probably get your robes on, Percy. And make sure you hide your Camp Half-Blood T shirt in your suitcase. We don't want to draw too much attention," she reminded me.

I grinned at her. "Well, of course, Wise Girl," I said in my best cowboy accent. "Ya didn't think ah would forget, would ya?" Annabeth rolled her eyes, because of course, she had totally thought that.

I grabbed my uncomfortable-looking wizard's robes out of my suitcase, which we had gotten, along with Annabeth's, from one of the Hermes kids ["Of course we didn't steal it!"]. They were already complete with the pre-ordered Gryffindor logo of a snarling lion and a red and gold tie. To be honest, even after a couple of months, I was still getting used to the idea of wizards. I mean, it was one thing to believe in other gods and goddesses, but witches and wizards were an entirely different realm.

"Are they, though? I mean they operate on the same premises as the Greeks and Romans, right? Monsters, magic, that kind of thing?" I realized I must have spoken aloud.

"I mean, yeah," I conceded. "But they have wands!" I took out the thin stick of wood from my jeans pocket and waved it around like it was the Holy Grail. According to a greasy old man named Olive something-or-other, it was rowan wood with a pegasus feather (aka Blackjack) core (Mr. Olive said it was inferior to dragon heartstring, but it would do), and Annabeth's was cherry and unicorn hair (at this, he had nodded approvingly; of course he did).

Annabeth gave me a long-suffering look, but I could see her hiding a smile as she told me to put my wand away and go change.

I pushed the door to the compartment open, my robes bundled in one hand.

I stepped out—only to immediately bump into someone.

"Excuse me!" said the girl indignantly, with a British accent. She had a big mane of bushy, curly hair and brown eyes. She was wearing witch's robes just like Annabeth.

"Oh, sorry—" I began, but I was cut off.

"Hey, watch where you're going!" said a boy's voice loudly. I turned away from the girl I'd bumped into, because I was pretty sure that nasally sound wasn't coming from her. The guy who interrupted me was pretty tall, and had Gryffindor robes just like mine (honestly, was everyone on the train a Gryffindor?), with his red and gold tie on in an uncomfortable-looking knot.

Also, he had orange hair. And I don't mean reddish-orange, like Rachel's (she's Camp Half-Blood's resident oracle) either. I mean genuine, dirty traffic-cone orange. It didn't pair well with his angry expression. I guessed the girl I bumped into was his girlfriend or something.

"Jeez, sorry," I said. "I didn't mean to bump into your girlfriend," The boy's face immediately went red.

He spluttered. "Girl—I'm not...I mean she's not—" His ears had turned entirely red, like a tomato.

Oops.

"I'm not his girlfriend," said the girl, who apparently wasn't his girlfriend. "I'm Hermione Granger. That's Ron," she pointed at the tall boy. "And you are?"

"Uh, I'm Percy. Percy Jackson."

"You're American," The girl—Hermione— told me. Yes, yes I am. She seemed to be studying me, with an expression that reminded me uncannily of Annabeth.

I didn't know what to say to that. "Yeah, so I'm just gonna go..." I said. I held up my bundle of robes.

"I haven't seen you around before," said Ron the redhead (orange-head). He still looked offended that I bumped into his 'not' girlfriend. "And you're American. How could you be a Gryffindor?" Ron asked suspiciously.

I quickly thought back to what Chiron said we were supposed to tell the real students of Hogwarts. "We're transfers. From Ilvermony. Er, Ilvermorny," I said. I really needed to get out of this conversation.

Ron still looked suspicious, but Hermione's face brightened. "Oh, so you know Railey? She's a transfer from Ilvermorny, too, though she's only a fourth year. She's a metamorphmagus, you know. And Muggle-born," Hermione said this like it was the highest compliment she could give.

I may or may not have zoned out when Chiron was talking about the politics of the magic folk, but I knew they had a massive gap between Muggle-born wizards, who were raised by mortals, I guess, and so-called pure-bloods, raised by other witches and wizards. It sounded depressingly like the real world.

As if summoned by the onslaught of words I didn't know, a girl who looked about fourteen wearing overalls and beat-up purple sneakers came skipping up to where we were standing in the hallway. Oh, and also rainbow hair. Like, Iris kid level rainbow hair, but it looked natural, not dyed. "Hey, Hermione," she said, glancing at me for a second and shooting a glare at Ron. It looked like those two didn't get along. I couldn't blame her. "Uh, I think your cat ate Ron's rat-bird," she said.

"Railey!" Ron exclaimed. "Why didn't you do something? And Pigwidgeon is an owl."

Railey ignored Ron, who was racing back to wherever their train compartment was, presumably to save his...rat-bird? Pig-owl? Instead, she turned towards me. "Who are you?" she asked bluntly. She reminded me of Meg, a daughter of Demeter who was Apollo's master for a while (it's a long story), but there was also something else about her. The crazy light in her eyes reminded me a little of Octavian, and that wasn't exactly a compliment.

"I'm Percy," I said.

Hermione chimed in, "He said he's from Ilvermorny, just like you, Rey." Railey narrowed her eyes. This wasn't good. What if this girl found us out because she didn't recognize us? Our quest would be ruined before it even started.

"Hmm…no he's not. And his girlfriend isn't either," she said finally. With that, she skipped back down the hallway, leaving Hermione and I standing in shocked silence.

So did you like that chapter? Hmm...is their quest ruined so soon? I had Percy go somewhere else to change into robes because 1) he needed to change out of his camp shirt and 2) he had to meet Hermione and Ron. Harry will appear later. I'll try to get the next chapter out by next week. Review if you want!

Now if you'll excuse me, I need to find the dam snack bar.
