Hi everyone! I'm managing to get this done before we get to the airport and I hope you like it. To Random Person, I am taking your suggestion into account and will definately do something like that. Yes the pets are going to have a minor part in the story, sometimes getting killed saving the owners. To WowangelaWow, Annabeth and Hermione will be fast friends and Reyna will be too. When Luna and Ginny come to Hogwarts, Calypso and Hazel will be their best friends. The rest will be besties with Neville, Ron and Harry.

Jason

The door swung open at once. A tall, black-haired witch in emerald-green robes stood there. She had a very stern face, and Jason knew he shouldn't mess with her.

"The firs' years, Professor McGonagall," said Hagrid.

"Thank you Hagrid. I will take them from here."

She pulled the door open wider. The entrance hall was so big you could have fit the whole Wolf House in it, Jason realized. The stone walls were lit with flaming torches, the ceiling was too high to make out, and a marble staircase facing them led to the upper floors.

They followed Professor McGonagall across the flagged stone floor. Jason held Piper's hand, already awed, hearing the drone of voices from a doorway to the right-the rest of the school must be here already-but Professor McGonagall showed them into a small, empty chamber off the hall.

"Welcome to Hogwarts," she said. "The start-of-term banquet will begin shortly, but before you take your seats in the Great Hall, you will be sorted into your houses. The Sorting is a very important ceremony because, while you are here, your house will be something like your family within Hogwarts. You will have classes with your house, sleep in your house dormitory, and spend free time in your house common room.

"The four houses are called Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. Each house has its own noble history and each has produced outstanding witches and wizards. While you are at Hogwarts, your triumphs will earn your house points, while any rule-breaking will lose house points. At the end of the year, the house with the most points is awarded with the house cup, a great honor. I hope each of you will be a credit to whichever house becomes yours.

"The Sorting Ceremony will take place in a few minutes in front of the rest of the school. I suggest you smarten yourselves up as much as you can while you are waiting."

Professor McGonagall's eyes lingered for a moment on Neville's cloak, which was fastened under his left ear, and on Ron's smudged nose. Jason saw Harry desperately try to flatten his hair, and Jason straightened his own cloak. Piper pulled a strand of hair out of her face, beads glimmering.

"I shall return when we are ready for you," said Professor McGonagall. "Please wait quietly."

She left the chamber.

"Will there be a sort of test?" Leo asked Jason nervously, looking green. "I hate tests. My ADHD always made me fail them."

"I hope it would be a gardening test," said Calypso. "I'd ace it."

"Any type of test would be fine by me," said Annabeth. "I memorized every single spell and all of the course books."

"You did?" asked Percy open-mouthed.

"Of course she did," Frank said bluntly. "She's Annabeth."

"That's right," said Piper with a laugh.

"Annabeth's always prepared," agreed Jason, inwardly laughing at the shocked expression on Hazel's face.

"If it's a fighting test we'd ace it," said Reyna, her obsidian eyes calculating the other students.

"With some casualties," agreed Hazel in a small voice.

"Don't worry," said Nico. "I could do some Underworld-y stuff and make them all disappear."

Harry and Ron poked their heads into the conversation. "I'm not exactly sure how they sort us," said Harry.

"Some sort of test, I think," said Ron. "My older brother Fred said it hurts a lot, but I think he was joking."

Then something happened that made Harry jump about a foot in the air-several people screamed.

"What the-?"

Piper gasped. So did all the students around them. About twenty ghosts had just streamed through the walls. Pearly white and transparent, they glided across the room, talking and arguing. They were saying some things about something they called Peeves, until something interrupted them. Jason wrinkled his nose. These ghosts looked nothing like the Lares at Camp Jupiter.

"Move along now," a sharp voice said, startling Jason out of his thoughts. Professor McGonagall had returned. "The Sorting Ceremony is about to start."

One by one, the ghosts floated away through the opposite wall.

"Now, form a line," said the witch. "Follow me. It'll be all right."

Feeling completely excited, Jason stepped in behind Leo, Percy, Frank, Nico, Ron and Harry, Piper, Calypso, Reyna, Hazel and Annabeth behind him. They walked out of the chamber, back across the hall, and through a pair of double doors into the Great Hall.

Jason loved it immediately, since it was lit by thousands and thousands of candles that were floating in midair over four long tables, where the rest of the students were sitting. These tables were laid with glittering golden plates and goblets. At the top of the hall was another long table where the teachers were sitting.

Professor McGonagall led the first years up here, so that they came to a halt in a line facing the other students, with the teachers behind them. The hundreds of faces staring at them looked like pale lanterns in the flickering candlelight. Dotted here and there among students, ghosts shone misty silver.

Jason looked up and saw a velvety black ceiling dotted with stars. He heard Annabeth and Hermione whisper as one, "It's bewitched to look like the sky outside. I read about it in Hogwarts, A History."

It was hard to believe there was a ceiling at all, and that the Great Hall didn't simply open on to the heavens.

Jason looked down again as Professor McGonagall silently placed a four-legged stool in front of the first years. On top of the stool she put a pointed wizard's hat. This hat was patched and frayed and extremely dirty. Jason zoned out, noticing that the other demigods did the same, with the exception of Calypso and Frank.

The hat sang a song that Jason ignored, but he snapped to attention when Professor McGonagall started speaking after the Great Hall burst into applause, holding a long piece of parchment.

"When I call your name, you will put on the hat and sit on the stool to be sorted," she said. "Abbot, Hannah!"

A pink-faced girl with blonde pigtails stumbled out of the line, put on the hat, which fell right down over her eyes, and sat down. After a long pause and Jason was getting bored-

"HUFFLEPUFF!" the hat shouted.

The table on the right clapped and cheered as Hannah ran to the Hufflepuff table.

"Bones, Susan!"

"HUFFLEPUFF!" the hat shouted again and Susan ran off to join Hannah.

"Boot, Terry!"

"RAVENCLAW!"

The table second to the left cheered; most Ravenclaws stood up to shake Terry's hand as he joined them.

"Brocklehurst, Mandy" went to Ravenclaw too, but "Brown, Lavender" became the first new Gryffindor, and the table on the far left cheered wildly.

"Bulstrode, Millicent" became a Slytherin. Jason thought about Malfoy, Crabbe and Goyle, also about what Chiron had told them about Slytherin, and immediately didn't like Slytherin.

"Finch-Fletchley, Justin" became a Hufflepuff, and "Finnigan, Seamus" was a Gryffindor.

"Granger, Hermione!"

Hermione almost ran to the stool and jammed the hat eagerly onto her head.

"GRYFFINDOR!"

"Longbottom, Neville!"

"GRYFFINDOR!" Neville ran away still wearing it, and had to jog back to give it to "MacDougal, Morag" who became Ravenclaw.

When Draco Malfoy was picked, he was instantly called out as a Slytherin. He went off to join Crabbe and Goyle, looking pleased with himself.

Jason looked around. Not many people were left now.

"Moon, Malaya" became a Ravenclaw, "Nott, Thoren" became a Hufflepuff, "Parkinson, Pansy" became a Slytherin, "Patil, Padma" became a Ravenclaw, and "Patil, Parvati" became a Gryffindor, then "Perks, Sally Anne" who was a Hufflepuff, and then Jason heard-

"Potter, Harry!"

Jason heard a bunch of whispers as Harry stepped forward, nervously dropping the hat on his head, and then-

"GRYFFINDOR!"

Harry went over to the Gryffindor table, his legs shaking, the Weasley twins that Ron had told them about jumping up yelling, "We got Potter!"

"Thomas, Dean" became Gryffindor, "Turpin, Lisa" became a Ravenclaw, and then Ron became Gryffindor.

"Chase, Annabeth!"

"RAVENCLAW!"

"Flamenco, Hazel!"

"SLYTHERIN!"

"Ramirez-Allerano, Reyna!"

"RAVENCLAW!"

"McClean, Piper!"

"GRYFFINDOR!"

"Titan, Calypso!"

"GRYFFINDOR!"

"Zhang, Frank!"

"GRYFFINDOR!"

"Valdez, Leo!"

"GRYFFINDOR!"

"Flamenco, Nico!"

"SLYTHERIN!"

"Jackson, Perseus!"

"GRYFFINDOR!"

Then it was finally Jason's turn. He was feeling queasy, and he knew by then that his face was turning green.

"Grace, Jason!"

Jason stepped forward, and the hat dropped over his eyes.

"Hmm," said a small voice inside his ear. "I see pain, bravery, a lot of courage, and a willingness to learn. You would do well in Ravenclaw, but you have ADHD, being a demigod."

"You can tell?" whispered Jason in surprise.

"Yes, I can tell," the hat cackled. "So, no Hufflepuff, not cunning enough to be in Slytherin, only a son of Hades or a daughter of Hades or Pluto could get into Slytherin, too restless all the time for Ravenclaw, so it'd better be GRYFFINDOR!"

Jason felt a stabbing relief, as he took the hat off and joined Piper, resting his head on the table.

Albus Dumbledore had gotten to his feet. He was beaming at the students, his arms opened wide, as if nothing could have pleased him more than to see them all there.

"Welcome!" he said. "Welcome to the new year at Hogwarts! Befoe we begin our banquet, I would like to say a few words. And here they are: Nitwit! Blubber! Oddment! Tweak! Thank you"

He sat back down. Everybody clapped and cheered. Jason heard Harry ask, "Is he-a bit mad?"

"Mad?" Percy W replied. "He's a genius! Best wizard in the world! But he is a bit mad, yes. Potatoes, Harry?"

Jason noticed that the empty dishes were now piled with food. There was roast beef, roast chicken, pork chops, lamb chops, sausages, bacon and steak, boiled potatoes, roast potatoes, french fries, Yorkshire pudding, peas, carrots, gravy, ketchup, and peppermint humbugs.

Jason was sitting next to Leo, across Piper, and Harry was at his side, Harry was across Ron. Piper was next to Frank, who was across Leo, and Percy and Calypso were facing each other.

Jason took fries with ketchup and salt, boiled potatoes and steak. It was all delicious.

"That does look good," said the ghost in the ruff sadly, watching Jason cut up his steak.

Leo looked up. "Can't you-?"

"I haven't eaten in nearly four-hundred years," said the ghost. "I don't need to, of course, but one does miss it. I don't think I've introduced myself? Sir Nicholas de Mimsy-Porpington at your service. Resident ghost of Gryffindor Tower."

"I know who you are!" said Ron suddenly. "You're Nearly Headless Nick!"

"I would prefer to be called Sir Nicholas de Mimsy-" the ghost began stiffly, byt Frank interrupted.

"Nearly Headless? How can you be nearly headless?"

Sir Nicholas looked extremely miffed. Jason fought the urge to laugh, but that would be cruel.

"Like this," he said irritably. He took his left ear and pulled. his whole head swung off his shoulders like a hinge. Someone had obviously tried to behead him, but not done it properly. Looking pleased at their stunned looks, Nearly Headless Nick flipped his head back onto his neck, coughed, and said, "So-new Gryffindors! I hope you're going to help us win the house championship this year? Gryffindors have never gone so long without winning. Slytherins have got the cup six years in a row! The Bloody Baron's becoming almost unbearable- he's the Slytherin ghost."

Jason looked over to the Slytherin table and saw a horrible ghost over there, with blank staring eyes, a gaunt face and robes stained with silver blood. He heard Harry laugh behind him; obviously he had seen that the horrible ghost was sitting right next to Malfoy, who obviously didn't like the seating arrangements.

A moment later the desserts appeared. Blocks of ice cream, Apple pies, treacle tarts, chocolate eclairs, jam donuts, strawberries, Jell-O, rice pudding and much much more.

Jason watched Harry help himself to a treacle tart, before choosing a block of apple cinnamon ice cream. Piper chose an apple pie, and Jason noticed Leo closing his eyes, holding a churro in his hand, one end already munched off.

"Just like my mother made them," Leo sighed.

"Reminds you of her?" Jason asked. Leo nodded, eyes on the Mexican sweet.

Then the talk turned their families.

"I'm half-and-half," said sandy-haired Seamus Finnigan. "Me dad's a Muggle. Mom didn't tell him she was a witch 'till after they were married. Bit of a nasty shock for him." The others laughed, Jason included.

"What about you, Neville?" asked Ron.

"Well, my gran brought me up and she's a witch," said Neville. "But the family thought I was all-Muggle for ages. My Great Uncle Algie kept trying to catch me off guard and force some magic out of me-he pushed me off the end of Blackpool pier once, I nearly drowned. But nothing happened until I was eight. Great Uncle Algie came round for dinner, and he was hanging me out of an upstairs window by my ankles when my Great Aunt Enid offered him a meringue and he accidentally let go. But I bounced all the way down the garden and into the road. They were all really pleased, Gran was crying, she was so happy. And you should have seen their faces when I got in here. They thought I might not be magic enough to come here, you see. Great Uncle Algie was so pleased he bought me my toad."

"Piper, and you?" said Harry.

"Well, we're all Americans, so we don't have that English accent," said Piper. "But my dad is an actor in Hollywood, so he shipped me off to a year-round camp, where I met Annabeth, Jason, Reyna, Leo, Calypso, Percy and Frank. But Dad was a Muggle, and he shipped me to the camp when I was nine. Mom was a witch, but she died when I was eight. So soon a I turned nine, Dad took me to the camp, where all of us got our letters."

"Dad was a wizard," said Jason, getting into his story as if that had actually happened. "But Dad died when I was two, having cancer. Mom went crazy, and my older sister Thalia, who had been learning home-schooled magic, couldn't take it anymore and took me to the summer camp, running away to the Hunters, where she still is. Mom died a day after Thalia left with me."

"And you, Leo?" said Hermione.

"Dad was a wizard too," said Leo. "But he went missing a few months after I was born. When I was eight, my Muggle Mom was killed in a fire. My Aunt Rosa wanted nothing more to do with me after that. She called me a little devil. I was shipped to foster homes...each one I escaped from and ran from. Every time, the police caught me and brought me to a different foster home. But soon I stumbled onto that summer camp. They accepted me without me paying, and I got my letter there. Calypso will tell you her story, eh, Calypso?"

Calypso glared at him.

"Fine," sniffed Calypso. "My father was a pure-blood wizard, and my mother was a muggle-born witch. But I was unexpected, and a soon as I could walk, I was sent to that camp. I never knew my parents, and a never cared. They abandoned me, and I got my letter. It also told me that my father was imprisoned for killing a muggle, and my mother went missing after that. Not that I cared, not at all. I made my own last name, and that's that."

"I'll tell my story," started Percy. "I had a happy life. But we all had ADHD and Dyslexia at that camp, aside from Frank, who got lactose intolerant. My Dad was a wizard, but he was a sailor and was lost at sea when the ship sank. My Mom, a muggle, was upset that I had those things, but she sent me to that camp, at my insistence, since I'd been kicked out of every school I put my foot in. But she was thrilled when I got my letter."

"My mother was a witch, as was my father," said Frank. "Of course, he was a wizard, not a witch. My father was killed in the battle with the Death Eaters, and my mother died in a fire when I was seven, so I went to live with my grandmother. She knew she was going to die, so she sent me to the camp when I was nine, where I got my letter."

Next to Jason, Harry clapped his hand to his forehead. "Ouch!"

"What is it?" asked Percy W.

"N-nothing."

At last the desserts disappeared, and Professor Dumbledore got to his feet again. The hall fell silent.

"Ahem-just a few more words now that we are all fed and watered. I have a few start-of-term notices to give you.

"First years should note that the forest on the grounds is forbidden to all pupils. And a few of our older students would do well to remember that as well."

Dumbledore's twinkling eyes flashed in the direction of the Weasley twins.

"I have also been asked by Mr. Filch, the caretaker, to remind you that no magic is to be used between classes in the corridors.

"Quidditch trials will be held in the second week of the term. Anyone interested in playing for their house teams should contact Madam Hooch.

"And finally, I should tell you that this year, the third-floor corridor on the right-hand side is out of bounds to anyone who does not wish to die a very painful death." Jason heard Harry laugh beside him, but he was one of the few who did.

"He's not serious?" Piper muttered to Percy W.

"Must be," said Percy W, frowning at Dumbledore. "It's odd, because he usually gives us a reason why we're not allowed to go somewhere-the forest is full of dangerous beasts, everyone knows that. I do think he might have told us Prefects, at least."

"And now, before we go to bed, let us sing the school song!" cried Dumbledore.

"Let us not," whispered Jason. Leo grinned mischievously, staring at the long golden ribbon coming out of Dumbledores wand that was twisting into words. It was a long day, and Jason zoned out as the school bellowed the song.

"Ah, music," said Dumbledore after they were done, wiping his eyes. "A magic beyond all we do here! Off you trot!"

The Gryffindor first years followed Percy W through the chattering crowds, out of the Great Hall and up the marble staircase. Jason had a good look at Harry then. He had black hair that was going everywhere, glittering Emerald green eyes that looked sleepy, and on his forehead-a lightning scar!

Jason nudged Piper and Leo, who looked at the scar, widened their eyes and nudged Percy Jackson, Frank and Calypso.

"The Lightning scar he is out to kill, like an unmoveable stone," whispered Calypso. "He's going to try and kill Harry!"

"We have to make friends with him, Ron and Hermione and Neville so we can protect them!" said Frank.

Just then, a bundle of walking sticks started throwing themselves at them.

"Peeves," said Percy W. "A poltergeist." He raised his voice. "Peeves! Show yourself!" Jason stopped listening.

"But someone has to keep an eye on Draco," said Piper in a low voice. "I have a bad feeling about him."

"We'll ask Nico and Hazel to keep an eye on him," said Jason. "They won't let him out of their sight."

They were interrupted by Percy W loudly saying, "You want to watch out for Peeves. The Bloody Baron's the only one who can control him, he won't even listen to us prefects. Here we are."

At the very end of the corridor hung a portrait of a very fat woman in a silk pink dress.

"Password?" she said.

"Caput Draconis," said the prefect named Percy Weasley, and the portrait sprung forward to reveal a round hole in the wall. They all scrambled through it-Neville needed a leg up and Percy Jackson tripped over him-and found themselves in the Gryffindor common room, a cozy, round room full of squashy armchairs.

The girls were directed through one door to their dormitories and the boys through another. "Well," said Piper sadly. "Bye." And she pulled Calypso through the door to their dormitory. At the top of the spiral staircase, there were a bunch of rooms. They were obviously in one of the towers.

They found their room at last-Jason, Percy, Leo, Frank, Neville, Ron and Harry shared a room together, with seven four-poster beds hung with deep red velvet curtains. Their trunks had been brought up already. Too tired to talk, they pulled on their pajamas and fell into bed.

"Great food, isn't it?" Ron muttered to everyone through the hangings. "Get off, Scabbers! He's chewing my sheets."

Jason agreed, but snores were already coming from Harry and Neville's beds. Frank laughed.

"I thought I could never eat again, I ate so much," he said.

"It was very exciting," said Leo, yawning. "I wonder wether we will meet Professor Snivellus Snake, he seems butt-kicking bad. I hate him already. It's just like Gaia all over again, Mistress of Potty Sludge, Queen of Dirt, Dirt Face. Only Master of Snivelling, King of Snake-rot, Snake of Evil. I wonder if-snore."

"And McShizzle Dude falls asleep mid sentence," said Percy from the other side of the room. "You, Frank, Ron and I are the only ones awake." A loud snore from Frank's bed countered him. And an even louder snore from Ron's bed countered him even more. "Okay," said Percy. "You and I are the only-snore."

Jason was going to ask wether he was still awake or only pretending, but he fell asleep immediately. He dreamt a strange dream.

He was wearing Gaia's Potty Sludge dress, and a giant was roaring at him to give up the mission, but then Piper came and destroyed the giant, only Gaia snatched back the dress and Jason found himself in Hogwarts robes, and Leo destroyed Gaia with fire, but Frank was destroyed too, then Malfoy came and killed Calypso and laughed, his dagger dripping with crimson blood, and then red washed over Jason's eyes, and then he saw Leo sacrificing himself to save him, and Annabeth was killed saving Percy, but Percy killed himself and Nico and Hazel were destroyed by the giantess, and then Jason was the only one left.

He woke up in the night, opened his eyes, closed them, and fell asleep again, but when he woke up in the morning he didn't remember his horrible dream at all.

A/N

So what do you think? I think I should go on. My best friend gave me the idea to have all of the boys in the same room. So? Put what you think in a review! My best friend (Ryann) says that my work is too private to share with the world, but I don't agree. So say what you think!
