Okay, let's do this. Yes, I know, these stories occur in different timelines, but for this crossover to work, Percy is seventeen and Harry is fourteen. Set in Harry's fourth year, during the Tri-Wizard Tournament. Alright, let's start writing this cliched and overused plot, then take it from there. Don't judge me.

One: Not Again…

Percy's POV:

Two words entered Percy's mind when he woke up.

Not again…

Seriously? He cursed the gods, all of them, as he realized that he was no longer at camp. Was this Brazil? Antarctica? For all he knew, he was on another planet.

He opened his eyes slowly, just in case anyone was watching. It didn't seem like he was on another planet, but you never know. The room was pretty big, with large wooden doors and stone arches holding up the ceiling. He was laying in a small bed, like the cots in the infirmary at camp.

The room seemed empty, so he took a small risk and sat up to look around better. There were more beds like his, all of them perfectly made with white sheets. Some had curtains around them, but none were closed. He looked down at himself and gave a silent thank-you. But not to the gods. Anyone but them. He still had his jeans, which meant that he still had Riptide.

Slowly pushing the covers down, Percy set his feet on the floor. He patted his pocket for reassurance and crept forward, not making a sound. He was almost to the big wooden double doors when the smaller door on the other side of the room creaked open. He froze, but instead of a monster, a large woman in a weird nurse's uniform came out. She was holding a stack of blankets, so she didn't see him right away. When she finally noticed him, she screamed in surprise and dropped them. He took that as his cue to run.

He turned around and pulled hard on one of the doors. It swung open towards him and he dashed through the opening before the woman could make another sound. He didn't have time to admire the architecture as he ran, but from what he did see, it was pretty amazing. Annabeth would have loved it.

Annabeth. Did she know where he was? Was she okay? Whoever sent him here was going to have a lot of explaining to do.

His feet hit the floor rhythmically as he tried to navigate the halls. Tried being the keyword. It was so confusing, he was probably running around in circles. Eventually, he came across a huge marble staircase that led down. He paused to catch his breath and noticed a strange amount of pictures on the walls. Weird.

Did one of them just blink?

Percy bolted down the staircase faster than he would have thought possible. He wanted out of this place.

He came across another set of giant wooden double doors, but they looked more intricate than the ones from upstairs. He pushed them open without a second thought, hoping they led to an exit.

He was so wrong.

Four hundred kids in long black capes sat at four tables, staring at him. There was a bunch of food that he didn't recognize and some important-looking people sitting at a table that was higher than the others.

He didn't know what to do. There were floating candles, and ghosts, and every instinct he had was screaming at him to run. But something was also telling him to stay. Well, not telling. More like commanding. His hand hovered over the pocket that held Riptide, but he didn't want to bring it out in front of a bunch of mortals. These people didn't look like any mortals he'd ever seen, though.

A really old man was standing at a podium, mouth half-open, as if he'd been talking before Percy had come through the door. He had a really long white beard and crescent-shaped glasses. He was all the way across the very long room, but Percy still found a part of his brain wondering if he ever tripped on all that hair.

Everyone was still for what seemed like hours, but was probably more like three seconds. Then the tables in front of him burst into whispers and noise. He wanted to run so bad, his legs hurt. But again, something made him stay. The important-looking guy with the white hair seemed to realize that the room was falling into chaos and bellowed,

"SILENCE!"

Immediately, the entire room hushed, but Percy could still feel all the looks. Some were curious, some were suspicious, and some just looked like they wanted to know who interrupted their dinner.

All of a sudden, his legs started moving. It was like he had no control over his own body, and he didn't like it. He walked stiffly between two of the tables towards the man. Percy was actively trying to turn around, but couldn't. Before he knew it, he was standing right in front of the guy as he quirked an eyebrow, waiting for him to speak.

He sighed inwardly, knowing that this was probably another quest that another god had assigned him. He couldn't leave until he finished it, whatever it was.

"Look, sir," he said in a hushed voice. "I just woke up with no idea how I got here. I think I'm supposed to help you with something."

It was all he could come up with. He'd never been good at all the lying and excuses stuff, mostly because he could never think of anything convincing. Annabeth was always the one who did. He swore she could probably convince someone that the sun was green and the earth was actually made of gummy bears. But she wasn't here. No one was.

Focus.

The man studied him, and it was kind of unnerving. His bright blue eyes seemed to see right through him, but Percy couldn't tell what he was thinking. He seemed harmless enough, but this close to him he could tell that the man could do some serious damage in a fight. It almost felt like he was a demigod. Questions pounded at the inside of his head, and he added them to the growing list of things to yell at the gods about.

He tried not to bite his lip as he waited for a response, whatever it was.

"Who are you?" he asked, not in a menacing way, but like he was genuinely curious. Percy heard a slight accent in his voice, maybe British? He didn't know what to say. Did he make up a name? Chances are the guy would find out his real one anyway, he seemed like the kind of person who did his research.

"My name is Percy. Percy Jackson." He watched the man carefully for a reaction. It was a good thing, too, because if he hadn't, he might have missed the subtle flash of recognition on his face. He covered it well, it was kind of impressive, but Percy knew he recognized his name from somewhere.

Before he could say anything, the man raised a finger, telling him to wait, and looked past him at the tables of kids, who were all staring.

"Students! What a lovely feast. Now that our stomachs are nice and full, I believe we will all need a long night's rest in preparation for the start of the school year. You are all dismissed to your dormitories, first years, follow your house prefects. Good evening, everyone!" To Percy, he said, "Follow me, Mr. Jackson."

He heard the accent again, but not enough to tell him where he was. Judging by the look of this place, he thought, probably not New York.

The students filed out of the hall, many of them looking back at him and whispering. The older people at the raised table (teachers?) started to get up, but the man raised a hand at them and they sat back down. He walked quickly down the length of the table, gesturing for Percy to follow him. He hurried after him through a side door that had gone unnoticed before.

The door led to a nice-looking room with a fireplace and two couches facing each other. There were some odd pieces of furniture here and there, but Percy really wasn't paying attention at that point. Well, more than usual. He just wanted answers.

Inside the room, the man relaxed and sat on the couch like he didn't have a care in the world. Percy sat across from him a little impatiently, waiting for him to speak. For a second, he thought he was going to, but the guy just reached into one of the pockets of his weird cape-thing and took out a small piece of yellow candy. He unwrapped it, humming a little song. Percy watched him with a blank expression.

The man noticed him staring and said, "Care for a lemon drop?"

Percy shook his head. He shrugged and popped it into his mouth.

"Now," he said, leaning forward a little. "Mr. Jackson. You have no memory of coming here?"

"No," he said. He just left it at that. He didn't know if he could trust anyone there.

The older man clasped his hands out in front of him and rested his elbows on his knees. He looked at Percy with his eyes sparkling in amusement. Like he'd read his mind, he said, "My dear boy, if you don't trust me, I can't help you."

Percy stiffened a little. He just wanted a straight answer, and here this guy was, laughing.

His frustration must have shown a little more than he'd thought it did, because all amusement disappeared from the man's expression. Before he could say anything, Percy stood up.

"Look. I don't know how I got here, or what I'm supposed to do. I just need information. Starting with where I am." It came out a little more aggressive than he intended, but the man just leaned back in his seat and looked at him passively.

"Currently, you are in Scotland, at the Hogwarts School of Witchcraft and Wizardry."

"I'm in England? Oh, this is just great. At least last time I was still in the same country." he muttered.

"Scotland," the man corrected.

"Whatever."

The man studied him quietly, like he was hearing a voice in his head. If he was a demigod, that might not have been unlikely.

Percy decided that if he was going to help these people, who were apparently witches and wizards, he had to know more.

He sighed, hoping the man wouldn't mind the sudden subject change. "Listen, I need to ask you something. Are you... aware… of the old Greek gods?" He waited as he looked at him thoughtfully.

"Yes, as a matter of fact, I am."

Good, that made it a little easier. "Well, they still exist."

Blunt, but true. There wasn't a great way to sugarcoat this. Fortunately, he didn't show any outward signs of disbelief. Did he already know?

"I know."

Really? When was the last time he'd gotten this lucky?

"A couple years ago, I happened across a woman who claimed she was the goddess of magic. Of course, I didn't believe it at first, but came to accept it. She told me that centuries ago, she blessed a specific group of muggles to be able to perform magic. These were the four founders of Hogwarts. After that, she almost forgot about it, and the four founders created a secret society of wizards. When she rediscovered this world, she was concerned about a certain wizard by the name of Tom Riddle. He called himself Lord Voldemort. He used magic for dark purposes, and gained a following of wizards that called themselves Death Eaters. He sought to rid the wizarding world of muggle borns and those he deemed unworthy, or that opposed him. Many died in those days. Fourteen years ago, Voldemort entered the home of James and Lily Potter, who were leaders of a rebellion against him. He killed them and tried to kill their son, Harry Potter, who was just a baby. But the Killing Curse somehow rebounded upon him, and he was never seen again. However, three years ago, the remains of his soul latched themselves onto a teacher here, and started forming a consciousness. He tried again to kill Harry, but failed. Two years ago, he tried to kill him again. Last year his most faithful servant returned to him, and I fear that this year they may make another move. So does Hecate, the magic goddess."

Percy whistled. "That's… rough."

The man stopped speaking for a moment and stood up, hands behind his back. He began to pace.

"I believe that you have been sent here to protect Harry. This year we are hosting a magical tournament that may be the perfect time for Voldemort to strike. Now, Harry is still underage, so he won't be competing, but he is still in danger."

Percy tried to interrupt. "Wait, if you know that this psycho dude might try to kill this poor kid again, then why are you going to-"

The man stopped pacing and peered at him through his glasses. It was pretty intimidating.

"Your job is to keep him alive."

How'd I do? I had a hard time trying to write Dumbledore, but I think I'd earn at least a passing grade. Hopefully.

Give me some feedback, let me know what you think. Leave a review! They make my day. Until next time,
