Percy Jackson and Harry Potter crossover

We have a lead...I think

A/n: So...a bit of a timeline change thingymajigger. (Sorry!) Just a heads up, some things that happened in the Harry Potter book will be mixed up...so yeah. For example, the Quidditch match is--technically speaking--supposed to be in this chapter. But it's not.

"So? What about now?"

"Not yet, Ron. Just lemme finish this chapter."

...

"Okay. What about now?"

"Harry, sshhhhhh! You're the one who gave this to me! Now quiet!"

...

"Well? How ab--"

Hermione exploded at Harry and Ron, slamming the book onto the table in front of them, rattling all the silverware and tipping over a goblet of pumpkin juice, all the while blowing dust into the faces of the people around them. Through the coughing and glaring directed at her, Hermione managed to wack the two boys on the head with her "cover" book. They both whined an "ow" and rubbed their heads.

"Will you two bloody shut up!!??"

Silence. Then, "Language, Her--"

"OH MY BLOO--AND LOOK WHO'S--RON I--" Hermione stormed off out of the Great Hall, the ginormous book tucked under her arm, leaving Harry and Ron sitting there with new-formed bruises. Ron sighed as he shoved a spoonful of pudding into his mouth.

"Bloody temper she has there." he said around the mush in his mouth. Harry looked away politely. Unconsciously, he traced the I will not tell lies scars on his hand, biting his lip. With Hermione gone with the book, there was nothing important to distract him anymore. His thoughts went to his dreams once more, and the Quidditch game that he had a bad feeling about. Harry almost drew blood from his lips as he thought about that. He sighed.

It seemed that nothing went right without something going wrong in all his years at Hogwarts. Harry mournfully spread his marmalade over the piece of toast he held in his hands, not absorbing the nervous energy from Ron beside him. Just as he peeled off the crust on his sandwich, someone slid into the seat next to him, plucked the toast from his hand, and ate it in two large bites. Percy blinked at him innocently with his chipmunk cheeks. He waved hello, and Harry mumbled it back, having his food getting stolen by Percy so much that he couldn't even get angry anymore.

He reached for another pair of toast.

"Ser..." Percy muttered, still chewing and swallowing over his words. "Gerd Lu..ck werth da Quidditch match tommorow." he directed towards Ron and Harry. Both of them smiled back, though Harry was friends with him long enough to figure out the, "Thanks. But stop reminding me." meaning behind it.

There was a snicker behind Harry as someone "accidentally" bumped into Ron, making him pitch forward and smash his head against the table. Draco full out laughed as he stalked away with his posy, his white blonde hair slicked back and silver and green scarf swinging around like he owned the world.

"Good luck, Weasley, on the Quidditch game tomorrow. Or should I say, good luck on not failing as bad!" Draco called over his shoulder, chuckling like what he said actually made sense. His Slytherin buddies shrieked "Weasley is our king" in a high pitch, girly voice, faking damsels in distress. 

Ron's ears turned red.

"Ignore him." Both Harry and Percy said, but Harry knew that both of them wanted to just go after Malfoy and strangle him. (instead, to prevent further violence from happening, Harry just tried to remember every embarrassing thing that Draco did and silently laughed in his head.)

There was a comfortable yet tense silence as the three boys continued on with their breakfast. Percy yet again stole the next piece of toast from Harry, shoved it into his mouth, then spit it back out.

"Ugh! Oranges!?" he asked, wiping his tongue while reaching for the pumpkin juice in front. Percy glugged it down, but still had a constipated look on his face.

"Ugh."

Harry was too tired to react. Instead, he settled for just some scrambled eggs. His mind was clouding on the edge of slipping to the repetitive dream he had been having and his Occlumency lesson with Snape that was coming up soon. Something he was looking forward to greatly. 

He miserably shoved a spoonful of eggs into his mouth and then rubbed his weary eyes, his lids feeling like they were weighed down by a troll. Harry's thoughts were interrupted when a dreamy, "Hello, Harry. Percy. Ron." said behind him.

Harry flinched furiously, completely caught off guard. "Oh, erm--"

"Helllo Luna!!!!" Percy chirped up beside him, turning his bright sea green eyes on the girl. Luna beamed back, her eyes a bit more focused then usual. But Harry didn't really pay attention to that. His eyes were on the huge, furry mess on top of Luna's head.

"Umm...er, Luna?"

"Mmmm?"

"What's that on your head!?" Ron cut in, his blue eyes widening at the hat--what Harry suppose was a Lion--that was perched on the blond's noggin.

"It's the Gryffindor's mascot. It's showing that I'll be cheering for your team." she explained. Her eyes glowed excitedly as she quickly exclaimed, "Look what it can do!"

Luna tapped the lion with her wand, and it let out a deafening roar that made everyone within a 50 feet radius flinch and cover their ears. 

Percy was chewing thoughtfully, gazing up at the lion. Then he did what Harry assumed was a smile, and lifted his hands up to his cheek in a thumbs up. Luna practically glowed in pride as she flaunted off, thanking Percy.

The rest of the day was a blur. He survived DADA, which was good...maybe. And by the time Hermione, Ron, and Harry all had a free time off, they huddled together around the huge Poseidon book, made sure that Percy was nowhere in sight and preoccupied with something else, then started their discussion. Well, more like them listening to Hermione as she spoke.

"I skimmed through most of them, but the only thing I learned is that Poseidon is the greek god of the seas, earthquakes, and more. He's part of the Twelve Olympians, and one of the oldest gods. His symbols include the horse, a trident--which is his weapon of power--, and dolphin, et cetera. His brother Zeus--who later became the king of the gods--freed him from his dad's, Kronus's, stomach and--"

"Wait!! Hold your horses!" Ron cut in. (again in that day...) Hermione paused, breathing deeply.

"Yes?"

"His dad's stomach!?" 

"Yes. Anymore questions?"

"Th--"

"Great. Continuing on. Poseidon fought with his kin to destroy his evil titan god, and then came the era of the gods. They sometimes...ah, interact with the mortals and produce people called demigods. Heracles is a famous example, son of Zeus. One of Poseidon's famous demigod kids include Theseus. Poseidon created the horse...Oh, and his roman form is Neptune, which happened when the Romans took over."

"...that's it?"

"Nope. Poseidon is--"

"Shhhhh!" Ron said, making a zipping motion. "That's good."

Harry, however, sat silently, mulling over the information that had just been dumped on him. For some reason, his mind kept going back to the part about demigods. His gut lurched whenever he thought about the children of the gods and Percy. 

His eye twitched. Wait...

"What about demigods again?"
