"Yeah right."

I turned to see where the voice came from. And it was from none other that Harry.

He said, "1. We defeated Voldemort by ourselves. So we'll defeat him and his new ally. 2. The Greek gods are just myths."

I opened my mouth to speak, but Piper cut me off, "The Greek Gods are real. I'm a Greek Goddess."

Harry looked at her and said, "Prove it."

Piper just smirked as she grew to her godly height.

All the students' jaws dropped. 

Harry looked like he was about to say something, but Ron pulled him down.

After that was over, I continued, "To correct your first statement Harry, you won't be able to defeat Voldemort's ally without us. Voldemort's ally is Kronos, Titan of Time, and Father of the Gods of Olympus."

This caused more whispers throughout the crowd.

A Gryffindor, who I recognized as Seamus, stood up and said, "I remember my mum telling me about Greek Mythology. And one of the things she told me was that Kronos was even more powerful than the gods. So even with your help, how are we supposed to defeat him? He's had plenty of time to plan his revenge."

Nico responded, "That's a good question. But we can defeat him. Many of you heard that about a year and a half ago, there were some weird things happening in New York. We demigods were tasked to defend Olympus, which is on the 600th floor of the Empire State Building, while the gods fought Typhon. Percy was our leader. He was the one who fought Kronos, and the one who defeated him."

Nico looked at me and said, "Re-introduce yourself, Percy."

I sighed, " I am Percy Jackson, Son of Poseidon. Retriever of Zeus' Master Bolt, Sailor of the Sea of Monsters, Retriever of the Golden Fleece, Bearer of the Sky, Savior of Artemis, Wanderer of the Labyrinth, former bearer of the Curse of Achilles. Subject of three Great Prophecies, one of the Seven, Retriever of the 12th Legion's Eagle, former Praetor of New Rome, Survivor of Tartarus and the Second Giant and Titan wars. I have defeated most of the Greek/Roman monsters at least once. Slayer of Kronos and defeater of Gaea. I fought in the Battle of the Labyrinth, Battle of Manhattan, Battle of Alaska, the Battle against Gaea, and countless smaller ones. I am the leader of numerous quests, the Second Titan war, the former boyfriend of Annabeth Chase, two-time Savior of Olympus, and champion of the Gods of Olympus."

All the jaws in the room dropped, except for Nico and Hermione. Frank spoke in my head, so only the demigods heard it, "Damn Percy. I only knew about half of that."

Leo burst out laughing, which caused the students to stare at him.

After he pulled it together, I announced, "To prepare you for this war, I thought that it would be best to host a boot camp. You all must attend, as this can and will save your lives. You may all go back to your dorms now."

Jason then said, "Well Percy, we can't stay any longer. We were tasked to return to Olympus once they were all informed of the war."

I nodded, understanding that they also have their own godly business to attend to.

Once they were all gone, I gave Dumbledore a list of things that I needed. He nodded and said that he would contact Chiron.

I thanked him and went back to my dorm. However, as soon as I entered the common room, I was met with cheers and clapping.

Confused, I asked, "What did I do? Is there something on me?"

Hermione face-palmed and said, "No, they're sorry about everything that they've done to you. They want to celebrate what you've done."

I looked around the room. I said, "I didn't do anything. I just did what other's weren't willing to do."

I made my way through the crowd and went to my dorm.

Harry and Ron were already there, talking, when I entered.

Harry was the first to notice my arrival. He spat, "You think you can come to Hogwarts, and take everything from me, including Hermione?"

"No, that was all your doing. I just wanted to live a normal life. I didn't even want to come to Hogwarts. You brought me here. And Hermione chose to stop being friends with you."

With that, I got onto my bed and went to sleep.

Dream

I was in a room with a long table. The seats were filled with wizards in dark robes, Death Eaters, and one of each Greek monster. On the ends were Kronos and Voldemort.

They were all in a deep conversation.

Kronos was saying, "We have just hit a minor setback. We underestimated the wizards at the school."

Voldemort spoke up, "Agreed. We also gave up the element of surprise. My sources have informed me that the students are fully aware of the war. Hogwarts is now in full lockdown. It would be very hard to attack the school again."

Kronos nodded, "Both the Greek and Roman camps are also going to be very hard. But there is one place."

Dream End

I woke up at about 5 A.M. and went to the Room of Requirement. I usually go their about four times a week to work on my powers. But today, I went to clear my mind.

I began to slash at a training dummy, trying to think of places that they would attack.

Before I knew it, it was 7:30.

Luckily, the Room of Requirement also created a shower room. I quickly turned on the water, and let all my sweat run off of me. I then turned off the water and went to the Great Hall.

Now I know what you're thinking. I should be going to the Great Hall soaking wet, but because I'm a son of Poseidon, I never get wet, unless I want to. And this wasn't one of those times that I want to get wet.

Harry POV:

I was eating breakfast with Ron when Percy Dickson came into the Great Hall. He sat down right next to Hermione, and was immediately in a deep conversation with her.

I glanced at Ron, who was eating like Ron, and asked him,"Do you have any idea of what they're talking about?"

Ron gulped down his bite and replied, "No. But I wouldn't mess with him. Especially today. He might go extra hard on us."

"Yeah, I guess you're right. But, why don't we show him up today. Prove to him that you and I don't need to go to his stupid boot camp."

Ron nodded before devouring his food.

After a couple minutes, V.G. went up to the podium. He announced, "Boot Camp starts in fifteen minutes, report to the Forbidden Forest by then."

Once he was done, I finished my food, and Ron and I went to the Forbidden Forest.

Percy POV:

Once everyone had arrived, I welcomed them all to Boot Camp, Week One.

I said, "Welcome. Boot Camp will be three weeks long, and each week, you will be taught something new. This way, you will all know the basics of what you will need to survive this war. This first week will be conditioning, getting into shape, and preparing for battle. Next week, you will all learn hand to hand combat. Even though you all have wands, you will need to learn how to defend yourself if you are ever disarmed. During the final week, you will choose your weapons from either a sword, dagger, or bow and arrow. You will not choose a weapon on which seems the coolest, but which works the best for you. Then, you will learn combat, based on those weapons. Any questions?"

I was hoping that nobody would answer, but like always, Harry Potter had to ruin it.

He asked, "Why do we need to have a conditioning week? We did good yesterday."

I sighed, "You guys did do a good job holding the Death Eaters off yesterday. But this camp isn't to just help you prepare for a fight against a Death Eater. It's to prepare you to fight Greek monsters. They won't care who you are. They'll attack you because they have nothing to lose. When you kill them, they'll go to Tartarus to reform. And in a matter of weeks, they'll be back."

I looked around to see if there were anymore questions. Thank the gods that there weren't.

I then said, "Alright. I'll start off with an easy warm up. I want everyone to do 50 push ups before doing 100 sit ups. Then after everyone's done, we're going to hold a plank for 2 minutes."

Some mouth's dropped.

I clapped my hands together, "Get moving!"

A few hours later...

All the wizards were warn out after the warm up. And by lunch, they were covered in sweat. I mean, how hard can a hundred burpees and forty suicides be?

But by 2:00, they were all dead. So I said, "Give me twenty jumping jacks, and then you can be done."

They all groaned.

I smirked, "You know what, just go. I'll see you tomorrow."

AN: Even though this book is still not even close to the end, I would like to know if you would like a sequel. It will move on from the Harry Potter stuff and focus on the aftermath of this war. The book will be a Percy Jackson Legacies crossover, without Landon dating Hope, that way there can be a Hope and Percy relationship. I haven't seen many fanfics based on this crossover, so it would be something different. I would be able to get creative and it would be easy to use any ideas that you guys come up with. With that said, please comment on this chapter with your answer, so I can plan the rest of the book accordingly. I think that you will all like it.
