This is the third story I've started this week. I'll attempt in keeping the others updated, but they might end up like every other story I've started. Unfinished, well, except for that one story I finished, but want to re-do. Yeah, life is just amazing.

Summary: Percy Jackson and the group, along with my OC, Kayla, travel to Hogwarts at first for the WizDemi competition the Wizarding world was throwing. So, how did they end up helping the defeat of Voldemort?

Kayla's POV

Percy, Annabeth, Thalia, Nico, Luna and I were in the Big House.

Why?

No idea.

Chiron was talking about a WizDemi competition to see which race is better. The Wizards, or the Demigods.

It was a little difficult for Luna, considering she has been going to Hogwarts and she is a Demigod.

Yeah...awkward for her.

Me? I was scowling the whole time. Petty mortals thinking they're better because they have a small tiny bit of magic.

Turns out, we are the chosen demigods to participate in the tournament.

A son of Poseidon, a two daughters of Athena, a daughter of Zeus, a son of Hades and one daughter of Hecate.

The thing that slightly annoyed us was that we had to pack immediately and shadow travel or transport to the Hogwarts Express, which was leaving any minute.

The worst thing: I never even had breakfast yet.

So we did.

Annabeth's POV

Luna was a little nervous missing the train, but she was relieved when Kayla transported us there.

Nico offered to shadow travel us there, but Kayla said it was to freaky and nauseating.

We all agreed on her statement.

To bad Kayla transported us into a compartment with four people staring at us.

A ginger headed boy had wide eyes. "Loony? What are you doing here?"

Us demigods scowled, minus Luna.

"Her name is Luna." Thalia said, her electric blue eyes just waiting to zap someone into the next titan war.

The ginger boy whimpered and hid behind a younger, female, look-alike.

"Wimp."

The ginger look-alike glared at us. "How in Merlin's hat did you just apparate in here? You're clearly under aged."

We all looked at my half sister for an explanation. "Transport. You're not allowed to preform magic outside of school grounds."

"Ooooh!" Percy said.

Kayla, being the moron she is, yawned and sat on a dude that almost looked like Percy.

A bushy haired brunette scowled. "You can't just sit on random people. And answer Ginny's question."

Kayla leaned back, putting her hands on her head, squishing the almost Percy look-alike against the wall. "We don't have to answer anyone if we don't want to."

"Come on guys, let's find a different compartment." I said, heading for the door.

The ginger boy stood in front of the door, holding a stick at us. His friends followed suit.

Kayla, who was now standing, burst out laughing. The rest of us demigods, besides Luna, were trying to hold back laughter.

"What's so funny?" the ginger girl, Ginny, demanded.

"Sticks! They use sticks!" Kayla practically screamed.

Apparently, the children of the Big Three couldn't take it either. They joined Kayla in the humerus laughter.

Luna and I looked at each other and nodded.

"Come on guys, we should find an empty compartment."

Nico pointed at the guy that looked like Percy. "Look! It looks like he thinks he can blast us to Tartarus!"

The four Hogwarts students seemed to shake off Nico's 'Tartarus' comment.

"How dare you talk to THE Harry Potter that way!" Ginny seethed.

Thalia snorted. "Oh look! We have names to!"

"He is the boy-who-lived!"

Nico rolled his eyes. "So? We're alive too."

Kayla took the chance to grab onto us demigods. "Three, two, one..BAM!"

She yelled and we disappeared.

Luna's POV

I giggled. "The 'BAM' was unnecessary, Kayla."

Kayla grinned. "I know, I just wanted to show them what a real magic person could do, no offence."

I smiled. "None taken. Compared to what you do, it makes this magic seem quite lame."

"So," Percy started. "Who were those people?"

"Harry Potter, Ginny Weasely, Ronald Weasely and Hermione Granger. Harry, Hermione and Ron are the so-called 'Golden trio'." I said.

Thalia nodded. "Yeah. They sure seemed a bit cocky though."

"Yes. It seems that they like to be the heroes. I think they're a bit power hungry for only being in their sixth year." I said.

Kayla then took something out of her backpack. A piece of parchment to be exact.

"Where did you get that?" Nico asked.

Kayla grinned. "Took it off of that Harry Potter kid. He's rather thick."

Annabeth shook her head. "That's what we get when she goes year rounder at camp with the Stoll brothers."

"That's the Marauder's map." I said, coming to realization. "That's pretty brilliant to steal."

Kayla tilted her head. "It doesn't look like a map."

She handed it to me. "That's because you need the spell for it." I took my wand out and tapped it on the map. "I solemnly swear, I am up to no good."

Kayla nodded as the map turned into an actual map. "It's a map of the Wart Hog train.."

"Hogwarts." Annabeth corrected.

"Yeah, whatever." Kayla replied, earning a scowl from my half sister.

Nico and Thalia looked over Kayla's shoulder to look at the map too.

"Heh, we're the compartment next to the...Golden trio is it?" Nico said. I nodded. "How long is this train ride?"

"We should be there soon." I replied.

"So," Percy started. "Why didn't we just transport to Hogwarts itself?"

That left us all dumbstruck.

"Maybe you're not so much of a Seaweed brain as I thought." Annabeth muttered.

We all looked at Kayla. "Transport time?"

"Oh yeah." We all grabbed onto her. "Three, two, one...STICKS!"

She yelled (again) and we disappeared.

Kayla's POV

I know it's unnecessary to yell those random words, but it's fun!

It was a little more rough teleporting into Hogwarts, because Luna told me that no one could...

We were all on the ground, but we were okay.

I heard a chuckle from an old man. We all turned and saw, well, an old man.

"Professor Dumbledore." Luna said, giving him a curt nod.

"Ah! You must be the Half-Bloods! Welcome to Hogwarts. I must inform you though, the WizDemi competition won't be for a while, so you will be taking classes here."

Oh.

Annabeth nodded. "So, we are in classes together, right?"

Dumbledore nodded. "Yes, you will be in the same class as Luna as well, although, you will all be sorted into different Houses, you will all be in the same classes."

We all nodded. Just as we were about to leave, the Headmaster said something else.

"And please, do not reveal that you are demigods until the tournament. Remember, use your weapons only if you have to. Please join up with the first years for sorting. The teachers also know of your...parentage. See you all at the feast."

Mmmm...a feast sounds really good right now...

uhhh...Reveiw?
