Percy Jackson and The Wizarding World

After their meeting with Dumbledore, Percy felt the weight of another quest settling onto his shoulders. Sure, he was used to diving headfirst into dangerous situations, but Hogwarts was a different kind of battlefield—one filled with secrets hidden beneath layers of magic and mystery.

Back in the Gryffindor common room, Percy spread out the notes they had taken from the Slytherin common room onto the table. Harry, Ron, and Hermione leaned over them, eyes scanning the scribbled entries and diagrams.

"So, we know that the Keeper's Vault is hidden somewhere in the castle," Hermione said, tapping a passage with her finger. "'Accessible only by those who possess knowledge of both divine and magical heritage.' That certainly fits you, Percy."

Percy nodded, rubbing his temples. "Great. I always wanted to be a human treasure map."

Ron frowned. "But if Malfoy's looking for it, that means his dad must know something. Maybe it's got dark magic inside?"

"Or something worse," Harry muttered. "If it's connected to Slytherin, it could hold ancient magic meant for—you know who."

Percy sighed, leaning back. "Well, we're not gonna figure it out just sitting here. We need to find the entrance before Malfoy does."

Hermione bit her lip, flipping through her notes. "There are a few places in Hogwarts where the magical energy is unusually strong—historically speaking, places like the Room of Requirement, the Astronomy Tower, and—"

Percy raised a hand. "Wait, what's the Room of Requirement?"

Harry grinned. "You'll like it. It's basically a room that gives you whatever you need. It only appears when you're looking for something specific."

Percy blinked. "You're telling me there's a magic room that can make anything appear? And we haven't been using it to our advantage this whole time?!"

Ron grinned. "Welcome to Hogwarts."

Later That Night – The Room of Requirement

Under the cover of darkness, Percy and the others crept through the halls of Hogwarts. Percy had his sword Riptide in pen form, but his instincts were sharp as ever, scanning for any signs of trouble.

Harry paced in front of the blank wall on the seventh floor three times, muttering under his breath. Suddenly, a massive wooden door materialized before them.

Percy let out an impressed whistle. "Okay, that's pretty cool."

The door creaked open, revealing an enormous chamber filled with stacks of books, ancient artifacts, and all sorts of magical relics. The air was thick with dust and magic, and Percy could feel something… different. A sense of familiarity, like the ocean's pull, but heavier.

Hermione stepped forward cautiously, her wand illuminating the room. "Be careful. We don't know what's inside."

They moved deeper into the cluttered room, searching for anything that might resemble a hidden entrance. Percy's fingers brushed against an old shield, and instantly, a ripple of energy shot through him.

"Whoa," he muttered. "Did anyone else feel that?"

Harry turned. "Feel what?"

Percy looked down at the shield. It was old, bronze, and covered in strange markings—Greek markings.

"This… this is Greek," Percy whispered, his heart pounding.

Hermione rushed over, eyes wide. "What does it say?"

Percy traced his fingers along the engravings, translating slowly. "'To the Keeper of Secrets, speak thy truth and enter.'"

Ron gulped. "That sounds ominous."

Percy took a deep breath. "Here goes nothing." He pressed his hand against the shield and whispered, "I seek the truth."

The ground trembled beneath them, and suddenly, the wall behind the shield shimmered, revealing a hidden passage spiraling downward.

"Nice," Percy said, stepping back. "Looks like we found our way in."

Harry exchanged a glance with Hermione. "Are we really doing this?"

Ron groaned. "Do we ever not?"

Percy grinned. "Come on, let's go see what's so special about this vault."

Inside the Vault

The passageway led them deep beneath the castle, the air growing colder with every step. The walls were lined with more Greek inscriptions, and Percy could feel the divine energy intensifying.

At the end of the tunnel, they reached an enormous stone door with an intricate trident symbol etched into it. Percy recognized it instantly—it was Poseidon's mark.

"Uh… guys," he said, staring at it. "I think this might be a little more personal than I thought."

Hermione looked at him curiously. "Do you think your father built this?"

Percy shrugged. "Maybe. The gods have a way of leaving their fingerprints all over history."

Harry stepped forward. "Well, only one way to find out."

Percy placed his hand on the trident symbol, and immediately the stone door groaned and shifted, opening to reveal a vast chamber filled with artifacts from both the wizarding and demigod worlds.

Golden statues of gods lined the walls, while shelves contained ancient scrolls and objects that hummed with power. In the center of the room stood a pedestal with an open book resting on top.

Percy approached cautiously, reading the Greek inscription beneath it. "'Knowledge granted to those who walk between worlds.'"

Hermione looked over his shoulder. "It must be a record of some kind… a connection between magic and mythology."

Percy flipped open the book, the pages glowing faintly as words rearranged themselves in front of his eyes. "Looks like it's talking about the Mist… the way it hides the divine world from mortals."

Harry frowned. "Why would it be hidden here?"

Before Percy could answer, a sudden chill filled the air.

"Intruders," a cold voice hissed from the shadows.

They spun around, wands and Riptide at the ready. Out of the darkness, a hooded figure stepped forward, their eyes glowing with eerie silver light.

"You should not have come here," the figure rasped.

Percy raised his sword. "Yeah, well, I have a habit of sticking my nose where it doesn't belong."

The figure raised a hand, and the room darkened as tendrils of black mist slithered toward them.

"Run!" Hermione shouted.

Percy gritted his teeth, holding his ground. "No way. We came here for answers."

Harry aimed his wand. "Expelliarmus!"

The spell hit the figure, but they barely flinched. The shadows around them only grew darker, swirling with ancient magic.

Percy lunged forward, slashing with Riptide, but the figure dodged effortlessly, whispering something in a strange, guttural language.

Suddenly, Percy felt a familiar tug in his gut—the ocean calling to him. He raised his hand instinctively, and water from the air coalesced into a swirling sphere around his palm.

"Bad move," Percy said, launching the water at the figure.

The shadowy tendrils hissed as they evaporated on contact, forcing the figure back. "You… are not of this world," they murmured before vanishing into the darkness.

Breathing heavily, Percy turned back to the others. "Well, that was new."

Hermione looked worried. "Who was that?"

Percy sighed. "No idea. But I have a feeling we're going to find out."

Harry nodded. "Then we better be ready."

Percy glanced back at the book, closing it and stuffing it into his jacket. "Let's get out of here before more creepy shadow people show up."

As they made their way back up the passage, Percy couldn't shake the feeling that they had just uncovered something far bigger than they could handle.

And he had a sinking feeling that this was only the beginning.
