Chapter 1: Something Strange Happens

Walking into his cabin at camp Half-Blood, Percy Jackson placed his glass of water down on the table. Today had been another exhasting one, full of training and what-not to become a proper Demigod. Grover, his best-friend-who-is-half-goat (He still hasn't gotten over the fact that his best friend was a saytr) soon bounded in after him.

"Have you seen Anabeth? I haven't seen her since the other day." Percy said, trying to act nonchalant.

Grover said, "Nope, sorry dude I haven't." Anabeth was the boy's close friend-who-is-a-girl (not a girlfriend!).

Percy said, "Hey Grover, do you think something happened to her?"

Grover looked at Percy,said nothing and started laughing.

When Grover looked at Percy with tears on his face from laughter and said, "Your serious aren't you. Don't you know by now that she could take care o0f herself, and then some?"

Percy hid the blush spreading over his face. "Yeah, well..."

He trailed off at the sight of the daughter of the goddess of wisdom herself ran in. The two boys didn't have any time to say anything to her before she pushed them down to the floor, and they finally caught sight of a huge mass of greenish-blue on the wall. The greens and blues swirled together. Percy's furniture began to slide towards the thing, and so did they.

"It's a portal!" Anabeth shouted. They slid across the floor, closer and closer, with nothing to hold on to, as everything stable was being pushed to the portal too.

"I'll grab hold of the edge of the portal and you hold onto me." Percy instructed, trying not to get sucked in.

Grover and Anabeth said, "Right." at the same time, and Percy waited until they were close enough before latching on to the side of the portal, Anabeth clinging to Grover and Grover clinging to Percy. All three were trying to figure out where the portal came from, and where it was going to.

Percy was losing his grip on the edge of the portal, and with a shock he noticed that it was closing. Before the edge could close around his fingers, he let go.

They all started to scream, none of them having knowing how long they had been falling through the portal before it started to open beneath them, and they crashed to the floor. Each one of them loosing their balance, they all fell backwards on a trio of people. Percy had fallen on a boy with messy black hair, and shockingly green almond shaped eyes. One companion on his left had red hair, blue eyes and freckles covering his face. The last was a girl with big, bushy brown hair and brown eyes. They all looked about the same age and all looked shocked that Percy, Grover, and Anabeth had fallen out of nowhere on top of them.

"Did anyone catch the license plate of the bus that hit us?" Grover said, sounding disoriented, and Percy was surprised he could even string a coherant sentance together.

The boy with red hair shook his head, as though trying to clear it. "Bloody hell! What just happened!?" And he looked immediately to the brown-haired girl.

She shook her head too, and said. "I have no idea. Maybe I should go to the library to see-"

"Hermione, I'm pretty sure there won't be anything there about this." The last boy said. "Who are you, and where did you come from?"

It was Anabeth who replied. "I'm Anabeth, and this is Percy and Grover." The Trio looked on in shock and amazement at seeing Grover's legs. "We're from Camp HalfBlood." This term was familiar to the trio, but it wasn't the kind of HalfBlood term they were familiar with. "Where are we now?"

"Hogwarts." The black-haired-boy said, and Percy and company took in that they had a strong Brittish accent. "What-"

But before he could say a word, the portal re-opened, and all four were sucked in. The rest of the students at Hogwarts didn't even see what happened, since everyone stayed away from the second floor corridor these days. The portal vanished just as quickly as it appeared, leaving no trace of it having even arrived.
