Unexpected Help

Chapter 1

"Hey Nico!" called Percy. He ran up the hill to catch up with Nico. "Chiron wants to see you at the Big House. Now." He sounded urgent.

"Why?" asked Nico.

"He didn't say, but it sounded important." Percy was worried. Chiron had asked specifically for Nico and by the look on the centaur's face – it couldn't be good.

"Alright then." Nico jogged to the Big House. He knew he could just shadow travel, but he didn't really feel like using energy on that.

At the Big House, Nico saw Chiron in his wheelchair form.

Chiron gave Nico a warm smile. "Ah, Nico..."

"Yes Chiron?"

"A friend of mine in England needs your assistance. I know I could've asked Percy or Thalia to do this for me, but I think Lord Hades would appreciate it if I sent you instead." Explained Chiron.

"Okay, what's the job?" said Nico.

"You'll have to help the students of Hogwarts defeat their enemy – Voldemort. It should be fairly easy compared to Kronos, but the wizards don't know that. They CAN'T know that." Said Chiron.

"So, let me get this straight. You want me to go to this school for these so called wizards and help them defeat their evil wimpy overlord?"

"Well, Voldemort is nothing compared to Kronos... but he can wipe out a whole race of wizards and has escaped death many times by dividing his soul into pieces. I just want to go help the wizards with this and if you have to: Kill him." Chiron looked grim.

"Sounds simple enough." Said Nico.

"And you can't let anyone know what you are. Understand?" Nico nodded. "Only the Headmaster knows that you are a demigod. Stay undercover and don't show your gifts until it is truly necessary."

"Got it. So... When do I leave?" said Nico.

"The train leaves in half an hour. Pack your things. Say goodbye to your friends. Then shadow travel to the Hogwarts Express at Platform 9 ¾."

Nico nodded. "Goodbye Chiron." He smiled. Chiron was like a second father to him. Nico left the Big House.

Harry, Ron, Hermione and Ginny sat in their train compartment, ready for their seventh year at Hogwarts.

"Can you believe it? It's our last year at Hogwarts!" exclaimed Ron. "Except for you Ginny."

Ginny scowled. "Thanks for reminding me, Ronald."

Harry and Hermione laughed. Harry enjoyed this. Moments when they don't dread about Voldemort.

It was just then, a boy no older than 16 appeared in their compartment looking very confused.

"Am I on the Warthog Train?" The boy had only a back pack and a dark appearance. He had pale olive skin, shaggy black hair, black clothes and a skull ring.

"You mean the Hogwarts Express?" said Ginny, looking at him up and down.

"Yeah that."

"What's your name?" asked Harry.

"Nico di Angelo."

"Are you new at Hogwarts? How did you do that by the way?" asked Ron, wide-eyed.

"...I guess you could say I'm new. I'm from America." Explained Nico, ignoring Ron's question.

"America?" said Harry, this was rather curious. Hermione seemed frazzled.

"What you did was against the law! That was an illegal move!" she accused, pointing her finger at him.

"What did I do?"

"You apparated!" exclaimed Ginny. "And you're under-age!"

"What's appara... what you said?" Nico scratched his head in confusion.

"It's –" Hermione was cut off by Nico.

"This is wasting my time." He said. Nico almost left the compartment until the train suddenly stopped and the compartment doors slid shut. Harry and the others looked out the window, trying to figure out what was going on.

"What in Hades..." muttered Nico as he tried to pry open the door. "Gods, it's locked." Nico sat on the empty seat next to Ginny (Who was quietly enjoying having an extremely hot guy next to her).

Suddenly, the door opened.

And a hooded figure entered.
