This is my first cross over fic. Please tell me what you think! Good? Bad? Awful? Ok?

Thanks for reading! Reviews make me happy! :)

Nico: Please review so she will shut up about her story sucking! Its annoying!

Me: Hey! I'm not annoying! And I worked hard on this so I think I deserve the right to ask for reviews! Its over 2000 words!

Nico: See what i mean. She never shuts up...

Summary: Nico, Percy, Connor, Travis, & Annabeth are sent to protect Hogwarts from Voldemort. They can't let anyone know they are demigods, easy, right?

Disclaimer: I do NOT own Percy Jackson or Harry Potter! Sadly...

Nico POV

"I think our tickets are messed up." Annabeth said with a confused look on her face, "There's no platform 9 and 3/4."

I could tell that she was stressed out because she didn't know everything about this place. Annabeth hated not knowing everything about everything.

"Woah!" Connor exclaimed from where he stood next to me.

"That guy just ran through that wall!" Travis finished from Connor's other side.

"Let's try it!" They yelled together earning many strange looks from the people at the train station. They really weren't doing very good at the whole keeping quiet and secretive thing. I had already had to drag Connor out of a store because he was about to pull a knife on some blonde kid, who had obviously been annoying him.

I was even blending in better than them. I don't blend in at all, with the shadows that seem to cling to me and the way I look creepy, according to a little girl I ran into in a store earlier.

"Nico! Where did Travis and Connor go?" Percy called to me.

Shit! They were gone!

I quickly began scanning the train station in hopes of finding the mischievous sons of Hermes.

I spotted them over by the brick column they had supposedly seen someone walk though earlier. They were face to face with these boys who appeared to be twins; they both had red hair and freckles.

"Connor! Travis!" I shouted at them. Now was not the time to mess around. "What are you guys doing?"

"This is Fred and George and they know how to get to the train." Travis responded.

"You just run through this wall." One of the red heads stated, as if it was normal to run through brick walls.

After we had found everyone and made it to platform 9 and 3/4, we boarded the train that would take us to the school. We were supposed to be American transfer students, and I guess they must not get a lot of transfer students because we had many people looking at us curiously as we boarded the large, black train.

"Let's go in this compartment." Percy suggested when we found an empty compartment about halfway down the train.

I sat on one side with Travis and Connor while the other side was occupied by Percy and Annabeth. I swear if they start getting all mushy I am going to put them in separate compartments.

"Hey, you two!" a voice sounded from the door of our compartment, "Wanna come put dung bombs in some Hufflepuff girls' compartments?"

I looked up to see the twins that Travis and Connor had been talking to earlier. They both had devilish grins on their faces. They were so much like Travis and Connor that I just stared.

"Sure!" the demigod brothers chorused, before following the red-headed twins out laughing. Travis and Connor were so similar that they were often mistaken for twins.

Well, now that I'm awkwardly stuck with the two lovebirds, I might as well try to get some sleep. I closed my eyes and tuned out their voices.

I only opened them when I heard the door to our compartment slide open once again. Couldn't these people just leave us in peace, was my first thought as I spotted a black haired boy with glasses, a girl with bushy, brown hair, and a red headed boy standing in the door way.

"Are you the American transfer students?" The brown haired girl asked noisily.

"Nope. We are rabid dogs that just fell from the sky & landed on this train." I retorted letting the annoyance I felt be clearly seen.

"Nico! Be nice!" Percy scolded me like I was some child. Then he addressed the annoying wizards standing in the doorway, "Yes. We are the transfer students. Who are you?"

"I'm Ron Weasley." stated the red-headed boy. I couldn't help but snicker at his name. Percy shot me a death glare, it didn't come close to my father's glares but it shut me up. The Weasley kid glared at me too but it just made me want to laugh more.

"I'm Hermione Granger." The girl with the bushy, brown hair stated, looking at Percy.

I waited for them to introduce the black-haired boy who was with them.

"Well, what's your name?" I growled impatiently at him.

"You don't know who he is?" Ron gasped in shock.

"Am I supposed to?" I responded, confused. I looked over and saw my confusion mirrored on Percy's face.

"You guys are so stupid sometimes." Annabeth huffed. "He's Harry Potter. The Boy Who Lived."

I remembered Chiron telling us about him while explaining our quest. He was the one that was supposed to destroy Voldemort, but apparently Voldemort had become more powerful of something so now we had to kill him.

"Oh. I expected you to be a little bit more intimidating." I stated truthfully, earning glares from Potter and his friends.

"Let's go sit down." Hermione said stiffly to her friends before they stalked off.

"Really, Nico?" Annabeth hissed as soon as the door slid shut. "You had to go and annoy Harry Potter and his friends. Everyone here probably looks up to him and now he is probably going to go tell everyone that we are rude and to avoid us. We are going to be outcasts now, and we have to become Harry Potter's ally and he probably hates us now, and-" Annabeth rambled on about Potter for like five minutes before Percy decided he should attempt to calm her.

"Annabeth, it's ok." Percy said putting his arms around her and hugging her. This made her relax and she finally shut up.

I rolled my pitch black eyes before getting up and heading for the door so I didn't have to watch them make out and be all mushy.

I started down the hallway only to find myself pulled inside of one of the compartments by my arm. I instantly went for my sword but stopped when I realized that it was Travis, Connor, Fred, George, and some red headed girl I hadn't met yet. Travis, Connor, and their twin friends that I couldn't tell apart were laughing so hard I thought that at least one of them was going to pass out pretty soon if they didn't quit laughing.

"What did you guys do?" I cautiously questioned, not sure if I really wanted to know.

"Hufflepuff...dung bombs...explosion" George or Fred, I couldn't tell, panted out between laughs.

"They put dung bombs in some girls' train compartments, and now, there are about ten girls who want them dead." The red haired girl clarified, "Oh, and by the way, I'm Ginny Weasley."

"Oh, uh, I met your brother." I said, recalling our not-so-pleasant encounter earlier.

"Which one?" she asked with a frown.

"Ron." I replied simply.

"Ugh. If he was rude to you I apologize, he has been very easily pissed off the past few days. I'm not sure why, though." Ginny mused. She was actually really pretty, even though she had red hair. I used to make fun of this one girl at camp and say that red heads were ugly, but I take it all back now.

Travis, Connor, Fred, and George had all left smirking and laughing, so I'm assuming that someone was about to get pranked.

I spent the rest of the ride to Hogwarts talking to Ginny. She was the first friend I had made outside of camp.

After about an hour, I felt the train start to slow down until we came to a stop.

I walked off the train still talking to Ginny and happened to run into the one person I didn't want to see, Ron.

"Ginny, why are you talking to him?" He demanded rudely.

"I'm talking to him because I can, and I don't give a damn about what you think!" Ginny fired back, matching Ron's anger. Obviously she was already mad at him about something else because she didn't seem like she was easily angered.

I guess this was abnormal for her because her brother's eyes widened and he looked speechless.

Ginny smirked before grabbing my hand and pulling me off. I was supposed to be transferring into my sixth year along with my friends, so we rode the carriages up to the school. They were pulled by these black horse like creatures that I remember seeing in the Underworld.

They pulled our carriage up to the school, which was huge. I don't think Annabeth will ever stop talking about its "magnificent architectural genius".

We followed the rest of the students to what appeared to be a huge dining hall. The ceiling was a dark blue with stars that looked so real that I wasn't sure if there even was a roof at first.

I was told to wait by the dour of the dining hall with by friends until we were sorted by a man who said to call him Professor Dumbledore.

"Nico Di Angelo, Perseus Jackson, Annabeth Chase, Travis Stoll, and Connor Stoll will be transferring to Hogwarts." the headmaster, Professor Dumbledore, said to the hundreds of students in the dining hall. "They will be sorted with the first years."

The doors to the dining hall opened and in came an old, uptight looking woman followed by a bunch of eleven year olds. I walked over with my friends and we waited at the back of the line for our turn to be sorted. Ginny had explained the sorting and the four houses. I hoped that I was in Gryffindor with Ginny.

The hat had been sorting students into the four houses, but I couldn't concentrate, stupid ADHD. I decided that looking around the expansive room was more fun than watching the other kids get sorted.

"Di Angelo, Nico!" called the old lady who had lead the first years in.

I reluctantly walked up to the stool where the worn out black hat sat. I was the last one to be sorted and all of my friends had ended up in Gryffindor. I really hoped I was going to be placed with them.

I walked up to the stool and placed the hat on my head.

'Hmm, interesting. You are very brave, but I sense a darkness to you. Perhaps Slytherin would be fitting or maybe Gryffindor.' the hat mused. 'Perhaps I look at your past will proof helpful.'

"No" I hissed quietly to the annoying hat. I could feel it probing into my mind.

'So much darkness and suffering!' The Sorting Hat exclaimed. It hadn't even gotten to anything bad.

I was getting so tired of sitting up here with everyone stating at me, that I decided to see if the hat would make a deal.

'Hey hat!' I thought hoping to gain its attention, 'I'll let you into my memories if you put me in Gryffindor.'

'Hmmm, why not.' replied the curious hat. It obviously had never heard the children's saying that went something like 'curiosity killed the cat'.

I let down the barriers I had put up in my mind and the hat saw everything.

There was a brief pause before the hat erupted in screams if terror, "GET ME OFF! AHHH! SO MUCH PAIN AND DEATH!"

I ripped it off of my head and it weakly croaked, "Gryffindor". Then it went limp in my hand.

I stood up and walked over to my friends, choosing to ignore the curious and scared stares I was receiving from the rest if the students.

"Shit. That went bad." I muttered, slumping into the seat next to Percy.

I didn't really talk much at dinner. I was still annoyed at that stupid hat for making everyone scared of me already.

I walked back to the Gryffindor common room with Annabeth, Travis and Connor.

We said good night to Annabeth before I found a bed, sat my stuff next to it and then proceeded to pass out from exhaustion.
