A/N Okay so this is my first story! Please follow favourite and review!

Percy POV

It was just a month after the second giant war and I was getting ready to go to New Rome with Annabeth.

There was a knock on the door.

"It's open!" I called thinking it was Annabeth. But instead of Annabeth, Leo came rushing into the cabin, out of breath.

"Big house, Hecate ,now!" He told me.

I groaned in reply. Why couldn't the three Fates leave me alone for once, just once I wanted to go to college with Annabeth without worrying about world destruction!

But nonetheless I went to the big house.

Annabeth was already sitting on a chair. Nico di Angelo was also there, sitting on the other side of the room, where the shadows were. Chiron stood at one end of the ping-pong table. But there was someone else there too. Beside Chiron stood a beautiful lady with a shimmering silk dress, holding two blazing torches in her hands.

"Hecate, what do you want?" I demanded. I know I should've probably knelt or something and thanked her for blessing us with her presence but at this point I wasn't sure why. I mean if they need demigods like me to save them then why?

Hecate simply smiled and said, "I want your help demigods." 'Wouldn't be the first time!' I wanted to yell but she continued,"There are some people I have blessed with the power of magic but now their civilisation is threatened by a dark wizard and Greek monsters are breaking through their barriers. Their magic is useless against the monsters. I want you three to go to Hogwarts: School of Witchcraft and Wizardry, teach them how to protect themselves and protect the boy named, Harry Potter, help him and guide him." I would've laughed at the school's name like who name there school hog warts? But the mood in the room stopped me from doing so. No one wanted to go but they had to.

"But we don't know anything about magic!" I pointed out.

"I have already thought of that, I will bless you and by tomorrow morning you will know everything you need to. You will introduce yourselves as exchange students from an American wizarding school and if they ask about your combat knowledge, tell them that your school has been getting attacked by them for a while." Hecate concluded and dissolved into the Mist.

I couldn't believe this. Just when I thought that I didn't need to worry about saving the world anymore, this happens.

Apparently, Hecate had already told Annabeth and Nico because both of them were silent as I stormed back to my cabin.

--The next day--

Annabeth POV

If someone had offered me a quest a few years ago I would've gladly taken it but now all she wanted was to settle down in New Rome with Percy. But nooo.

Yesterday I was so happy because once in New Rome I didn't need to worry about anything. Just as I was packing, Hecate decided to give me another quest. Why couldn't I have a quite and peaceful year for once! Ugh!

Anyway, I had woken up with the worst mood possible. Ignoring my splitting headache I freshened up and went to the Big House.

Nico was already there. He wore his black aviator jacket over his usual black T-shirt with a white skull. His silver skull ring gleamed upon his index finger. His black Stygian iron sword was attached to his belt. He wore black jeans. His dark sneakers covered his feet. He had a pale olive complexion but he looked even paler than usual.

"Hey, Nico!" Annabeth called.

"Hi. I talked with my father last night for information," Nico started.

"That's great! Did he tell you something?"

"Well, he told me about the dark wizard. Apparently, his name is Tom Marvolo Riddle and he cheated death. He split his soul into seven parts."

"Oh"

I didn't know how we could kill someone who had already split his soul. It was so completely wrong.

At that moment Percy walked in.

"Chiron wants us to meet him on the Halfblood hill" he informed us.

Chiron, Hecate and an old man stood at the hill.

"Good morning, children! This is my dear friend Albus Dumbledore! He is the headmaster of Hogwarts: School of Witchcraft and Wizardry. He will be accompanying you on your trip to Diagonal Alley where you will buy your supplies with these." Chiron handed each of us a simple drawstring pouch. I opened it to see golden coins with crowns engraved in them. "Galleons," I said. I didn't know how I knew but I just did. I figured it was Hecate's blessing.

"And sickles," Nico added

"And knuts," Percy added

Sure enough underneath the galleons were silver and bronze coins as well.

"How will we get there?" I asked

The answer came to me as soon as I asked but before I could answer myself Dumbledore spoke.

"Side-Along Apparation. Because You aren't legally allowed to apparate You will hold onto me as I do so" He explained. "Kind of like shadow-travel" Nico commented.

Harry POV

I had just awoken in the leaky cauldron. I rushed downstairs to be greeted by Ron and hermione.

"Hey mate! We didn't know you were here too!" Ron said

"Have you heard about the exchange students?" Hermione inquired.

"What exchange students?" I asked. I hadn't gotten any letter about that. It must've come after I left Privet Drive.

"There will be some Americans studying with us!" Ron explained.

"I don't think this is a wise idea, with Sirius Black's escape. Bringing unknown people into Hogwarts doesn't seem so smart. They could be helping him!"Hermione informed us of her opinion. I did think of it as a fair point but Dumbledore would know if that was the case, wouldn't he?

•o0O0o•

After breakfast, we went to Diagon Alley because Ron wanted to get Scabbers checked and Hermione wanted a pet. We were just about to enter the Magical Menagerie when we met Professor Dumbledore " Good morning, Professor Dumbledore! Are these the exchange students, Professor?" Hermione asked. Sure enough, three American teenagers were standing beside Professor Dumbledore. "Why, yes, Hermione. And I am sure they would love to introduce themselves." Professor replied. The tall dark haired boy with sea green eyes stepped forward to introduce himself. He wore a plain orange T-Shirt with jeans.

"Nice to meet you, I am Percy Jackson, son of-"

"Sally Jackson" the blonde girl with stormy grey eyes completed. She smiled at us and introduced herself, "Annabeth Chase, Pleasure to meet you" She shook hands with Hermione, then she stepped back and glared at Percy. Meanwhile, the last American, a pale boy with dark hair and eyes such a dark brown they seemed to be black, stepped forward and introduced himself as Nico di Angelo.

"They will be staying at The Leaky Cauldron tonight," Professor Dumbledore informed us.

"Oh that's great! We are staying there too!" Hermione exclaimed.
