Percy Jackson stumbled into his cabin, zombielike. He collapsed onto his bed (nearly missing it) and almost immediately fell into a deep sleep.

The problem with demigods is that they cannot simply fall into a dreamless sleep; they nearly always have visions or dreams when they sleep. This harp proven to be a major source of annoyance for Percy Jackson, because what 16 year old boy doesn't like his sleep?

This night didn't prove to be any different from the others. When Percy's head hit his pillow almost immediately a dream started to form in his mind.

Percy was standing alone in what looked like a train station. he was standing beside a brick wall in between two platforms- nine and ten. A damp mist covered the floor and hung slightly in the air, causing Percy's breath to come out as a white cloud. He repressed a shiver.

Suddenly a boy with black hair walked towards Percy with two other people, most likely his friends. They stopped about ten feet away from him and stood in a huddle, leaning their heads in so they touched each others. One of the people was a girl with busy brown hair, and the other was a tall and gangly boy with bright orange hair. They were whispering about something that Percy couldn't hear. He tried to move closer to the group, when suddenly a voice said, "Harry Potter," -the boy with black hair jumped slightly- "a boy who became great because he had no choice. Percy Jackson," -Percy's eyes widened- "a boy who was born great, but because of a mistake. Both are heroes, but because of different reasons." A high pitched laughter followed the announcement, sending a cascade of shivers down Percy's spine.

The three friends leaned together once more. They seemed to be bickering. Finally the boy Percy recognized as Harry Potter slowly made his way over to Percy, who was frozen in place.

"Harry, wait!" the girl with busy brown hair exclaimed, her voice laced with worry. Percy noted that they all must be British because of their accents.

"Hermione, it's fine. I'll be right back. He wouldn't dare attacking us now," Harry said. He was staring at Percy with a bemused expression.

"What are you?" Percy questioned Harry.

"I'm a person," he answered, sarcastically. "What are you?"

"I'm hungry!" the boy with orange hair called out. Hermione smacked his shoulder.

"Ron, shut up!"

"I'm- I'm a demigod," Percy answered truthfully. Harry knitted his eyebrows together.

"Like a half god?"

Percy nodded. "My dad is Poseidon."

"Oh!" Hermione squealed. "You're Greek!"

They were taking this better than Percy thought they would.

"Hush, Hermione," Ron said cheekily. Percy smiled as Hermione scowled.

"They're quite strange, aren't they?" Harry asked. Just then the station began to shake.

"Harry, we need to go. He's nearing," Hermione said, suddenly serious.

"Who?" Percy asked, but no one was paying attention to him.

"Ron, you have your wand, yeah?" Harry asked.

"Of course I do," Ron said and rolled his eyes. "What kind of wizard would I be if I didn't carry my wand? And no comment on our second year."

Wait- they were wizards?

"Come on, guys. He'll be here any moment!" Hermione said frantically.

"Who?" Percy demanded.

"Harry! Come on!" Ron shouted. The three wizards ran out of Percy's line of sight, leaving him alone.

Percy woke up with a start. He looked over at his alarm clock and found that it was still only 3:30 in the morning. He grumpily pulled the sheet over his head, and fell back into a deep sleep. He didn't think of the dream until much later, reasoning it was probably stupid. Wizards didn't exist. Only the children of Hecate existed- right?

So, I've had this idea in my head for awhile (even before I got a fanfiction account!) now, and I've just started to write it down. I'm super pumped for it, and hope you guys are too! It's a bit AU (Percabeth doesn't fall into Tartarus, Percy and Harry are the same age and Sirius doesn't die- I love him too much!) but I hope you enjoy it anyways!
