The sky was a dark gray, and rain was pouring down. Far away various jets of green light were shot and several people fell down, their face frozen in a scream. A old man with a silver beard and sparkling blue eyes sighed.

"Lumos." Dumbledore said, pointing his wand at the rain. He tossed in a coin an old friend gave him.

"Hello Dumbledore," A centaur said. He was smiling with many happy children running behind him, "Is there anything you need?"

"Hello Chiron I see you've gotten even more campers. Our war is unfortunately going very badly. Harry is still young and unfit to battle Tom. I know he is nothing compared to Kronos and the Titans so I would greatly appreciate if you could send some of your brighter demigods over to help us."

"Well Dumbledore, I normally would send Percy or Annabeth since they're probably the best fighters I've had in quite a while. Thalia is also busy with the huntresses, and I believe the best person to send in this situation is Nico. You see his father, Hades, is rather upset at Tom for cheating death. I'll send him over but please don't reveal his identity until I send some other people over. Oh and he should be put in sixth year since he is now sixteen years old."

"Thank you Chiron. This is perfect since Harry, Mr. Weasly, and Ms. Granger are also in sixth year. I agree to your terms." Dumbledore then waved his hand through the mist. Things were brightening for the wizarding world.

(The next day)

"Chiron what did you want to talk about?" Nico asked. He walked into the big house casually.

"Well Nico, a friend of mine is having problems in world. Big problems such as an oncoming war. One boy is supposed to kill the man that is the most evil of them all. That man has cheated death. Unfortunately things are not going well and we need you to help them." Chiron replied.

"What type of people are they?" Nico was curious. How did they not hear of another war, and who cheated death.

"Wizards. A group of people Hecate has blessed. They want you to come to a wizarding school known as Hogwarts." Chiron replied. When Chiron finished his sentence Nico started laughing.

"Hogwarts? Who names a school Hogwarts? And won't people notice something is wrong since I can't perform magic? And why am I the only one going?" Nico asked in between laughs.

Chiron ignored the first two parts of his question, but answered the rest, "Hecate has blessed you so you will be able to perform magic in the school," He then took out what looked like a stick and handed it to Nico, "This is your wand. You are the only one going because I believe you are powerful enough, and your father is upset that someone cheated death. I will send Thalia, Percy, and Annabeth to come later on. Now do you accept this quest. If you do read this paper and you will know where to shadow-travel travel to."

Nico thought it over a bit then nodded, "I accept. Bring it on." He went over and read the paper it read

Kings Cross station 9 ¾

He then shadow-traveled away, aiming for a compartment on the train. He fell and landed in what looked like a train compartment.

"Success." He said. He yawned and turned around to see a red-head boy with freckles, a girl with bushy brown hair, and a boy with black hair, glasses, and a lightning scar pointing sticks similar to his own at him.

"Aw Hades."
