Summary:

Nico Di Angelo was absolutely sick of this quest, and absolutely sick of wizards.

HP and PJO/HoO crossover strays from canon

Author's Note:

Hello all.

Please excuse any errors, it has been a while since I've read the canon stories for either series, and longer since I wrote for Harry Potter. This is my first time writing with PJO/HoO characters, so excuse me if I get them wrong for a while. I'm still learning.

Now that that is out of the way, enjoy the story!

Chapter 1

Nico paced back and forth in between platform's nine and ten at King's Cross Station, absolutely lost. He had been told to go to platform 9 ¾ in order to board the train to Hogwarts, but he was realizing now what the problem with that was. Damn was he wishing he had been given more information.

He had been in the middle of searching for Percy, when he was approached by a woman in a black cape, skirt, and hunting boots. He could tell right away that she was no mere mortal.

"Nico Di Angelo, son of Hades." Nico frowned, suspicious, but said nothing. The woman smiled gently. "Don't worry, young demigod. I'm not going to hurt you."

"Who are you?" He asked, unsure of whether or not the woman was a Goddess or a threat.

"I am Hecate, goddess of magic, perhaps you have heard of me?" Nico nodded.

"I'm sorry, I should've recognized you." He apologized, bowing slightly.

"It's alright. Now, I have a quest for you." Nico internally groaned, hoping his face remained neutral. He didn't have time for a quest! He had to find Percy!

"Of course. What do I have to do?"

"The wizarding world is on the brink of war. A man, perhaps you have heard of him from your father, named Tom Riddle or Voldemort, has been avoiding death for years, and has begun to rise to power again. Your quest is to protect his main target, Harry Potter, and find and destroy any of Voldemort's horcruxes located at Hogwarts. A horcrux is an item that a dark witch or wizard has placed a piece of their soul in. Riddle has created many of these horcruxes, but over the years, a few have been destroyed. You will be attending Hogwarts as a fifth year student. Only the headmaster is to know who you really are, or what you are doing."

Nico nodded.

"Good. The term begins on September 1st. You will board the Hogwarts express from platform 9 ¾ at King's Cross Station in London. That is all I can and will tell you." With that said, the woman raised her arms, and chanted some words. Nico felt a strange warmth spread through his body. "You have received my blessing, and will be able to perform the magic needed to blend in. You will find your Hogwarts letter and instructions on getting to Diagon Alley in your pockets. This will be your wand." She handed him a long thin box. "It will help you control your powers better than any of the wands sold to normal wizards will. I must leave you now. Good luck, hero." Nico bowed again, and when he straightened up, she was gone.

"Di Immortales!" He muttered, grabbing his luggage cart and looking around. He caught sight of a strange looking group of people with similar luggage to his own, and a mangy black dog.

'Perfect.' He thought, smirking. He watched them closely as one by one they ran straight through the wall between the platforms. 'Why didn't I think of that?!'

Nico quickly followed suit, shutting his eyes as he made contact, opening them again as he walked out onto a crowded platform covered in what he assumed were witches and wizards. Trying his best to ignore the sadness he felt inside as he witnessed happy families bidding each other farewell, he boarded the train. His experience with family wasn't exactly the greatest. Too much death and territorial uncles…

Nico quickly found an empty compartment and sat down. However, soon after the train began to move, there was a small group forming in the doorway. The bushy haired girl at the front smiled at him before speaking.

"Hello, do you mind if we sit with you? Everywhere else is full." He nodded, scooting closer to the window. The girl who had spoken stuck out her hand after sitting down. "Hermione Granger." He shook her hand, nodding.

"Nico." He said simply.

"This is Ron and his sister, Ginny. And that's Neville, and Loone-Luna and…" She hesitated here. Nico raised an eyebrow.

"And…?" The final person in the compartment looked at him sheepishly.

"I'm Harry Potter."

'Ah. Him.'

"Okay." He said, noticing how pretty much everyone in the cabin either sighed in relief or looked at him incredulously. He just shrugged it off.

"Excuse me for asking, but you aren't from around here are you? I mean, you sound American, and I've never seen you before. You must be too old to be a first year, correct?" Hermione asked, giving him a good look over.

"I'm an exchange student." Nico answered. 'Or something like that.' The answer seemed to satisfy the group, and they quickly began talking about other topics, ignoring Nico all together. He didn't mind much. He was pretty used to being on his own anyway and sometimes preferred it.

After changing into their robes some time later, the train came to a stop and the students began to unload.

Nico followed the group to the carriages, keeping quiet as Harry and Luna discussed the threstrals. He felt better around the creatures. The feeling of death radiating off of them made him feel at home, as sad as that was.

His letter had told him to take the carriages to the school, as the headmaster had been alerted to what might happen if Nico tried to cross the lake.

Soon, they reached the castle. Nico was stopped by a stern looking witch who introduced herself as Professor McGonagall.

"Wait here for the first years to be sorted." She said as they stood outside the great hall. "You will be called in and introduced as an exchange student and sorted separately." Nico nodded, fiddling with the sleeves of his robe. He really missed his aviator jacket…

After what felt like forever, he heard himself being introduced and the doors opened up. Taking that as his cue to enter, Nico walked into the great hall, hearing students whispering to each other, and gasps from the ghosts. All the spirits bowed down before him, much to his annoyance.

'They're gonna blow my cover!'

He sat on the stool, as directed by Professor McGonagall, and sat perfectly still as a ratty old hat was placed over his head. Before he could comprehend how weird that was, there was a voice in his head that was not his.

"Hello, son of Hades. Where shall we put you?"
