Hey everyone. Holy crap this became my priority story. Kind of heavy exposition chapter, but those are necessary every so often. Hope I justified Wizards and Demigods existing in the same world properly.

As always, Read and Review. Constructive Criticism is welcome.


Chapter 3- Migraines

Little Whinging

The letter came at breakfast that same morning, the day after Percy arrived in England. The mental meltdown came shortly after said breakfast.

Harry spent most of the meal stuffing his fist in his mouth to try keeping himself from laughing. He couldn't help it, since it was the most lighthearted meal, he had experienced at the Dursley's home he had ever witnessed. Percy looked absolutely miserable. The dinner he had with the family the night before had been bad, but Percy was so tired he didn't remember it. Now, however, Percy was wide awake, and his taste-buds were being assaulted.

Percy poked his scrambled eggs with a fork, watching sadly as the burnt eggs cracked underneath his fork. He halfheartedly chewed his bacon shards. He didn't even bother with the soggy toast. Harry was trying desperately not to laugh at the utterly depressed face of Percy. Percy couldn't help it. His mom had always been an amazing cook, and the camp's food was always delicious.

Petunia had made breakfast, wanting to make a meal to show much they appreciated family. Percy had received the message loud and clear. Petunia, Harry, Dudley, and Percy were sitting at the table eating breakfast. Vernon was sitting in the living room, talking on the phone with a friend.

Dudley was currently shoveling food into his mouth as fast as he could. Harry had explained that the family was on a diet. By the looks of it, they could use it. Petunia had decided to skip one day for Percy and her 'Ickle Diddykins.' Percy had broken into an uncontrollable and mysterious coughing fit when that came up, and Dudley had simmered murderously behind Petunia.

Petunia sat, drinking a cup of tea while reading the newspaper, trying her best to ignore Harry and Percy. The moment Percy had befriended Harry, the Dursley's had promptly decided that Percy deserved the same treatment. As such, he was ignored and looked down on with disdain.

Suddenly, Vernon stuck his head into the kitchen. His eyes were bugged out and his face was three shades of red, and he was glaring at Harry.

"Boy! Come here," He growled at him, before disappearing back into the living room. Percy silently glanced at Harry with a raised eyebrow, as if to say, 'What did you do?'

Harry shrugged before standing, clearing his dishes, and following Vernon into the other room. He immediately spotted the source of Vernon's distress and sighed mentally. This would be a fun conversation. Hopefully Percy didn't catch wind.

A large barn owl was perched on the living room window sill, pecking at the window to be let in. It was glaring at Vernon with a particularly baleful and ruffled expression, as if it knew that Vernon was preventing it from doing its job.

"Boy, I told you that we weren't to see any of your freakish abilities," Vernon growled at Harry, also glaring at the bird as if it personally offended him. It probably did in all honesty.

"I don't control owls," Harry said, sighing mentally. He knew exactly how this conversation would go already. Harry made for the window, intending to open it.

"Do you know what would happen if the neighbors discovered your perversion? We'd be the laughingstock of the normal people here," Vernon growled, stopping Harry by grabbing his collar with a plump fist. He glared at Harry with hate.

"Then I'd better let the owl in. Otherwise the neighbors might see it, and discover my … perversion," Harry said, knowing what words to use to get his uncle to fall in line. It worked. Vernon's hateful glare into Harry's eyes turned fearful and worrisome, and it turned from Harry to the windows. Already, the neighbors across the street in Number 3 were out and about. Mrs. Wilkins was weeding her garden and Mr. Wilkins was mowing their lawn. Vernon released Harry, and Harry opened the window and held out his arm.

The Barn Owl hopped onto Harry's arm, a letter with the Hogwarts seal attached to its leg. Its gaze never wavered from glaring at Vernon. His uncle didn't stop glaring at the owl, though he did move to the opposite side of the room, picking up the broom in the corner for defense.

Harry untied the letter, setting it aside, before setting the owl on the windowsill. It lingering, it's gaze never leaving Vernon as Harry returned to the letter. He picked it up to view but was interrupted by Vernon.

His uncle walked over to the windowsill, approaching the owl warily, holding the broom in front of him like a spear.

"Psst. Shoo. Psst-psst. Go on. Scram you overgrown canary," Vernon muttered, repeatedly stabbing the broom towards the bird. The owl eyed him with disdain, before taking flight, hooting unhappily. It flew a circle around the living room and pecked Vernon on the way out for good measure, who angrily swatted the air with his broom, only managing to catch a vase and send it shattering to the floor. The owl gave one more disgusted hoot before flying away into the morning sky.

Harry smirked, before turning back to his Hogwarts letter. Wait. Not his Hogwarts letter. And indeed it wasn't. The envelope was addressed to Percy, written in green ink and stamped with the Hogwarts Crest.

Mr. Perseus Jackson

The Smallest Bedroom

4 Privet Drive

Little Whinging

Surrey

Harry couldn't help it. It was so absurd and illogical. The fact that the first family member he enjoyed also turned out to be a Wizard while the rest of his family hated both him and the idea of magic was hilarious to him. He began to laugh.

…..

Percy watched as Vernon and Harry disappeared into the living room, before going back to poking at his food. He would have to call his mom soon, or at least mail a letter. He was just a little worried about using phones. While he was outside the land of the Gods, he didn't want to push his luck with phones.

Thud. Thud thud. Smack.

A series of odd noises came from the living room. Percy looked up, and saw that Dudley and Petunia were also looking up, confused. There was a crash, and they stood to go investigate. They found Harry holding a letter and laughing, the window to the room was open, a broken vase scattered on the ground, and Vernon was standing with his back to the kitchen, holding a broom and spluttering angrily, making more noises than actual words.

"Petunia!" He managed to choke out, turning around to find himself face to face with Petunia, Percy, and Dudley, all looking very confused. Vernon nearly jumped out of his skin when he saw Harry, a look of abject horror crossing his features.

With difficulty, Harry managed to stop laughing, before handing the letter to Percy. He looked at the letter, not understanding what the big deal was. Petunia and Dudley's looks of confusion turned to disgust at the sight of the letter, before turning to fear when they read Percy's name on the letter. Percy looked at the entire family oddly, with the Dursleys acting like they had received a lifetime ban from McDonald's and Harry acting like Percy had just won the lottery.

"Vernon…Vernon! What do we do?" Petunia hissed, trying and failing to keep from being heard. Percy turned back to the letter. It was obviously for his as it was addressed to him in green ink. It looked very formal, as there was a dark grey wax seal holding the envelope shut. Oddly, the envelope didn't have any postage stamps on it.

"Open it. You'll like it. It's good news." Percy looked up to see Harry staring at him intently, a wide grin on his face. "This is brilliant. Wait until I tell Ron and Hermione."

"What is it?" Percy asked, slightly worried about the very mixed reactions to the letter.

"A letter from my school. Trust me, it's good news," Harry said, nodding towards the letter. With that, the Dursleys ran out of the room. Percy could have sworn Vernon muttered something about 'Those ruddy wizards.'

Percy eyed it warily, before glancing at Harry who looked like he was about to burst from excitement. Was he being accepted into Harry's school? That wouldn't explain why the Dursley's were terrified of the letter, like it was a ransom note for their 'Ickle Diddykins.' Percy opened it, unsure of what to expect, and began to read.


HOGWARTS SCHOOL OF WITCHCRAFT AND WIZARDRY

Headmaster: Albus Dumbledore (Order of Merlin, First Class, Grand Sorc., Chf. Warlock, Supreme Mugwump, International Confed. of Wizards)

Dear Mr. Jackson,

We are pleased to inform you that you have a place 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.

Yours Sincerely,

Minerva McGonagall

Deputy Headmistress


Percy read the letter. It took a while. He squinted and turned the paper, embarrassedly admitting his dyslexia to Harry, stubbornly refusing his cousin's offer of help. He managed to read it. Then promptly had to reread it several times, because it seriously hurt his brain reading. Hogwarts? We await your owl? Mugwump?

He confusedly looked over at Harry, who was still grinning broadly at him. Harry rarely smiled. Maybe it was because of the Dursley's and Privet Drive, he didn't know. All Percy really knew was that Harry only smiled at the really funny jokes. He often wore a mask, at least here with his relatives. The mask was off, and he beaming ear to ear, as if Percy had busted out Riptide and knocked the Dursleys down a few pegs. Hmmm, not a bad idea.

Witchcraft and Wizardry. It was absolutely absurd. That treacherous voice in the back of his head nagged at him, though. After all, he'd done the absurd. He beat up a demon cheerleader with cymbals and a drum kit last year. He met Captain Blackbeard and his Celery Toting Scalawags a couple years before that. What if, that voice niggled at him.

"So…?" Harry prompted.

"Nice joke Harry. Seriously, well done," Percy said weakly, a sinking feeling in the pit of his stomach. "I mean it man, that letter gave my dyslexia schizophrenia."

"No, Percy, it's not a joke. You can come to school with me," Harry said, walking up to him. He looked like he wanted to say more, but at that moment, the doorbell rang. Harry walked over to the door as Percy stepped back, his hand drifting to the pocket where Riptide was always hidden. Harry opened the door and Percy tensed, waiting for an attack.

Instead of some freakish Greek monster wearing random pieces of clothing like someone clicking randomize in a character creation menu, an elderly man in a business suit stood on the doorstep. Percy wasn't fooled. Monsters came in all shapes and sizes. He was supposed to be hidden in Britain. That meant that if this old man was a monster, it was a lot more powerful than its appearance.

Luckily for the man, Harry recognized him.

"Professor Dumbledore?" Harry asked, opening the door to let him in.

"Hello Harry. How has your summer been?" The elderly professor said, walking into the house.

"It's been fine. Brilliant since Percy arrived," Harry said, shutting the door. The professor walked into the living room. The Dursley's watched him like a hawk from the kitchen, peering around the wall, only their beady eyes visible.

"Might we all have a seat? Your relatives can join us," Dumbledore said, his eyes twinkling mischievously. Percy smirked as the Dursley's heads disappeared into the kitchen at the same time. There was some angry whispers that Percy couldn't make out, before they fearfully filed out of the kitchen, sitting in one of the couches. Harry and Percy had a seat on the other couch, while Dumbledore took a seat in one of the armchairs.

"Now then, on to business," Dumbledore said, pulling out a stick and waving it around in the air. All three Dursley's slumped over, falling back into the couch they were sitting on. Dudley slumped into Petunia, and immediately began snoring into her lap, while Petunia's head fell backwards. Vernon slumped into the armrest, his thumb coming up to his mouth, and he began sleeping soundly. Harry didn't fare much better. He passed out and leaned back, his glasses slightly askew.

Percy leapt into action. Years of demigod combat training took over. He didn't know who this old man was, but he was obviously a threat. He sprang to his feet, his shield expanding from the wristwatch and Riptide being drawn from his pocket. He stood slightly crouched in front of Harry,

instantly wary of the man in front of him. He would have immediately started swinging, except for the fact that Dumbledore behaved rather oddly to these actions.

To Dumbledore's credit, he looked remarkably unfazed, even downright cheerful. He merely tucked the stick back into a pocket of his suit, before folding his hands in front of him and examining Percy.

"Relax Mr. Jackson. They are merely asleep." Percy didn't relax at those words.

"Who are you, what did you do to them, and what the Hades do you want?" Percy bit out.

"I am Albus Dumbledore, Headmaster of Hogwarts School of Witchcraft and Wizardry. I merely put them to sleep for a moment. I wish to have a private conversation with the Demigod that just arrived within our country. Who's your parent?" Dumbledore asked, his eyes twinkling as if he knew something Percy didn't. He probably did. Percy didn't view himself as stupid, but he definitely wasn't the brightest.

There was a long pause as Percy contemplated the man. No, the wizard. When the silence began to become awkward, Percy slowly lowered his guard. The shield and sword were still out and ready, but he couldn't detect any ill will from the man. Just curiosity, as if Percy was a rare specimen of fish that he was discovering.

"Poseidon. You?" The man had to be a demigod to be able to instantly spot him. But why was he in Britain.

"Me? Oh I'm no demigod. I'm mortal. However, I know about much of your world. Long ago, in the 1940's, our worlds collided with each other. We discovered each other and worked together. Since then, I have done much of my own investigating and made my own discoveries."

"You mean World War 2?" Percy asked, knowing that it had been the cause of the Pact that his father had broken.

"Precisely, my boy. In my younger years, I met one Mr. Chiron Brunner. Together we formed a pact to defeat the son of Hades, Adolf Hitler, and a dark wizard who was rising at the same time, Gellert Grindelwald." Percy's head began to hurt.

"Wait, back up? Wizard?" He said putting Riptide down to pinch the bridge of his nose with his free hand. Yup, the Fates hated him. From Gods to Wizards.

"I'm sorry, I should start from the beginning. Long ago, the Gods walked the Earth. You are familiar with parts of this story. As you know, the Mist separates the divine world from the mortal world. You will also know that clearsighted mortals exist. These mortals have always been able to see through the mist. What you may not be aware of is that those mortals are capable of magic. Their innate ability to see through the Mist allows them to pull magic from the divine world and harness it. Are you following me?" Dumbledore explained. It surprisingly made sense. It explained why Rachel was able to navigate the Labyrinth at the very least.

"Yes, but does that make my mom a wizard?" Percy asked.

"A witch, and no, not necessarily. Clear sighted mortals are clear sighted because of their imaginations and powerful minds. It allows them to see beyond the Mist. Hecate is the Goddess of the Mist and of Magic. Long ago, I believe that she granted some individuals the innate ability to perform magic and their powerful imaginations allowed it to flourish. They became the first witches and wizards. Now days, clear sighted mortals have the chance to become a witch or wizard spontaneously, while other witches and wizards are descended from the original followers of Hecate," Dumbledore said.

Percy was silent as he processed. It was a lot. It was worse than that time Annabeth took him to the Statue of Liberty and spent her time swapping between correcting the tour guide and giving him a detailed history lesson of every square centimeter of the statue. He didn't think he could get a worse headache.

"Ok. So. Clear sighted mortals can become witches and wizards because of their imaginations. Witches and wizards exist because of Hecate. Some are descended from her followers. Why Britain, and not America where the Gods exist?" Percy said, rubbing his temples hard, his distrust of Dumbledore forgotten.

"Oh, we exist in America too. There are communities of us all around the world. Similar to demigods, we exist outside of the knowledge of Muggles."

"Muggles?"

"Mortals. Non-magical folk. People who are clearsighted and become a witch or wizard are referred to as Muggleborns. People who are descended from the original followers of Hecate are referred to as Purebloods. Halfblood as you know it means Demigod, but Halfblood as we know it refers to someone whose parents are a Muggleborn and a Pureblood. A squib is a nonmagical person born to magical parents.

"Muggle sounds like a pathetic cartoon character, Pureblood sounds pretentious, Halfblood is just confusing, and Squib just sounds like the animal," Percy said critically, raising an eyebrow skeptically. Dumbledore laughed.

"Perhaps."

"So, magical people live all over the world. What does that have to do with me and Harry?"

"As I said, I am the Headmaster of Hogwarts. It is a magical school where young witches and wizards train to learn magic. Harry here is a student at my school. He is a Halfblood. Your aunt Lily was a Muggleborn. I actually met your mother once when I came to speak with Lily," Dumbledore said.

"Wait, my mom knew about wizards?" Percy asked in disbelief, his head reeling once again over that particular revelation.

"Yes, she did. She was very supportive of her sister's gifts."

"You still haven't answered. Why me?" Percy said, suddenly shooting the Headmaster a look.

"You are a Muggleborn. Simply put, I am here to offer you a place at my school," Dumbledore said, studying the young man in front of him.

"Nope. I'll pass," Percy answered, immediately knowing his stance on magic, godly or mortal. Muggle. Whatever.

"Alright, I understand," Dumbledore said simply.

"I've had more than one harebrained magical quest and you are not about to- Wait. What? What's the catch?" Percy stopped mid-rant.

"There's no catch. You don't have to learn magic. I won't force you. You must remember Mr. Jackson; we are not Gods. We do not force everyone to act on a stage like puppets. You are free to step away from the Wizarding World. However, you may want to act after you have heard about Harry's part in our world. I fear he is danger," Dumbledore said, leaning forward.

Percy rolled his eyes internally. There's the catch he asked about. There was always something. Something that just had to draw him in. His damn loyalty to family and friends. They meant everything to him, but he still hated that he always had to make the choice harder for himself. It certainly would be easier for him. He sighed, putting his shield away and slumping back, resigned.

"What about Harry?" He said, already accepting the fate of being a wizard. And so he sat. Sat and listened to the tale of Lord Voldemort and how he came to murder Harry's parents, Lily and James. How he had survived a curse that should have definitely killed him as a baby. How Dumbledore believed that Harry was in great danger from something forming on the horizon.

Harry was his friend. Harry was family. Hell, Percy almost considered the kid a younger brother and he had only known him a couple days. The fact that neither had their parents and that both of them had shitty childhoods just made him feel for the kid more.

Percy had become a demigod, and he had been all alone. Annabeth, Grover, and Luke had been his only allies at first. He had gained some, and lost others. But he had suffered. He had scars. He went through many ordeals by himself or with a small group of friends. It wasn't fun and he regretted ever doing most of it.

Harry had the same path in front of him. A life of suffering and pain and hard choices and constant fighting. A family member. Someone he was already close to. He couldn't in good conscious leave Harry to suffer through the upcoming ordeals alone. Not when he could help guide Harry and try protecting him.

"What do I have to do?"
