Harry's P.O.V.

As soon as we got back to the compartment, Hermione launched a volley of questions at Nico. I feel sorry for the kid.

"So," she was saying, "where are you from?"

"America," Nico replied, and I couldn't help but notice that he doesn't like to talk much.

Hermione frowned, "I didn't know Hogwarts takes transfer students."

Nico hesitated before saying, "My father wants me to transfer to this school because he thinks I'll get a better education here."

Now I was suspicious; why did he hesitate? Is there another wizarding school in America? That was unheard of.

Apparently Hermione was having the same thoughts, because she asked, "There's a school of magic in America?"

"Of course, but more like a camp," Nico said.

Now all three of us were thoroughly confused. A magical camp in America? My day just got worse. I hated not knowing, especially with Voldemort back.

"How come Dumbledore never talks about it?" I asked him, confused, "No American school showed up for the triwizard tournament."

He shrugged, "Maybe you guys are not the only ones good at hiding secret schools/camps," his tone indicating the end of that subject. There has to be something he's hiding. Nico apparently didn't want to answer any more questions, because just then he curled up on the bed and fell asleep, or pretended to be sleeping, anyways. I gestured for Hermione and Ron to come closer to talk about Nico.

"Well, what do you think of him?" Ron asked.

"I don't know," I said truthfully, "he could be a Death Eater, I mean, it's like he has a dark aurora or something." I cast a suspicious glance at the sleeping boy.

"We'll have to keep an eye on him," Hermione decided, "he could be working for You-Know-Who, attending Hogwarts just after You-Know-Who comes back." We all decided to spy on Nico, at least until we find out more about him. Looks like we have some serious work to do under the invisibility cloak this year.

Nico's Point of View

The trio looked pretty curious about me, Harry and Hermione especially. I told them part of the truth, except you have to replace "wizarding camp" with "demigod camp" for it to be true. At least they didn't ask who my father was. I'll have to think of some explanation for that later. 'This is ridiculous', I thought, 'how am I supposed to convince them?' Now they're huddled together, apparently talking about something. Me. I tuned in on their conversation (a good thing about being a demigod: great hearing to sense monsters…or people talking about you).

"…could be a Death Eater…" Harry was saying. I had to bite my tongue to keep myself from laughing. Death Eater? As in Thanatos eater? I'd like to see the "Death Eaters" try. I doubt he would be very tasty, if at all. Besides, who would want to eat Death? These wizards have some pretty weird names. The rest of their conversation was as confusing as the thing about Death Eaters. Hermione mentioned You-Know-Who, which I'm 100% sure is not his real name, wait, he could be that Tom Riddle/Voldemort person! The description by Hades and Hecate fits him. Feared by wizards. Check. Has a group of followers who terrorize people for him. Check (Death Eaters, who else would have such a ridiculous name for his followers?). Just came back. Check (it has to be the horcruxes, making him almost immortal). So apparently they think I'm associated with Riddle. Great. The mission just got harder, assuming that they'll be trying to follow me to see where I'm going.

I was still thinking about what Harry had said when I felt an odd sensation that told me death is near. I told the trio that I'm going sightseeing and went to investigate, following the radar that's pointing me to the direction of it. Suddenly, I saw it. The shadow minion was walking along the through the corridors of the train, causing it to stop. Everywhere it went; it seemed to suck the happiness out of things. My father uses them to guard the Fields of Punishment instead of just regular skeletons. What was this one doing here? He should be down in the Underworld, guarding the Fields. I stepped into the shadow, making them wrap around me so I would be invisible to any wizard observer.

"Τι κάνεις εδώ; (What are you doing here?)" I hissed in Greek as it recoiled in surprise at finding a son of Hades here.

"Έχω παραγγείλει από το σκοτεινό άρχοντα να βρει Χάρι Πότερ, κύριέ μου. (I have been ordered by the Dark Lord to find Harry Potter, my Lord)," it said.

"Μην εργάζεστε για τον ίδιο, (Don't work for him.)" I said, "Πάρτε πίσω τα πεδία τώρα (Get back to the Fields right now)."

"αλλά- (but-)"

"Ρωτήσατε για το σκοπό αυτό, (You asked for this)," I sighed, then made a crack appear on the ground and, just like what I did to the skeletons that chased Percy and Bianca 3-4 [A/N: I'm not sure how long ago that was] years earlier, watched as the shadow minion got sucked straight through the train of the floor and into the crack, which then closed up. Exhausted, I walked slowly back to Harry's compartment and this time, slept for real.

Harry's Point of View

Something was up. The train suddenly stopped, just moments after Nico went sightseeing on the train. I silently went to the corridor to see a Dementor. Surprisingly, it stopped and hissed in an odd language that I've never heard before. I was close enough to hear another voice, Nico's, except a) he was speaking the same odd language, and b) there was nobody in sight. Now my suspicions about him being a Death Eater was confirmed. He was definitely working for Voldemort. Then a really strange thing happened. The Dementor suddenly let out a scream as it was sucked through the floor of the train and into the ground before I got the chance to cast the Patronus spell at it. I ran all the way back to my compartment moments before Nico staggered in and fell asleep on the bed. I told Hermione and Ron what I had just seen, and even Hermione was as confused as me.

"Interesting…" she murmured, "he talked to it in a odd language, then…dispelled it? Into the ground?" When I nodded in confirmation, she continued, "That doesn't sound like what a Death Eater would do."

"So what did that sound like?" Ron asked, exasperated.

"I really don't know," Hermione said, "I'll have to look up more about him in the library." I knew she hated admitting that; Hermione liked to know everything.

"Don't worry," I said confidently, "we'll find out more about him when we get to Hogwarts."

Nico's Point of View

After I woke up from the nap feeling refreshed, I looked through the school supplies to kill time. I found a quill and ink bottles. What time period was this? Seriously? Why do wizards like old fashioned stuff? I also found some scrolls and books for the classes I'll be taking. Thankfully Hecate had enchanted them so that they'll be Ancient Greek instead of English, which is a little better, but still bad for an ADHD demigod. After going through all the supplies, I felt the train slowing down. We've arrived at Hogwarts (I had laughed uncontrollably when I heard that name, it just sounds so ridiculous). Still, I want to see what this secret wizarding school looks like.

Okay, finally finished! That was a long train ride. Next Chapter will be the Sorting Hat and the entire welcoming feast.

A/N: Percy will definitely be appearing in later chapters, and please review!
