Enemies or Allies? Harry Potter and Percy Jackson crossover.

My Cousins Planet Predicts the Future

Edited

A/n: every picture that I posted with the chapter is gone. Fun fact, my therapist said, "your anxiety is debilitating." So, I think that means I'm winning at therapy. Ok, carry on.

Percy:

Today's the day the demigods come for the dance. Not much has happened over the past month except for monsters regularly attacking. We also have been able to confirm it's Typhon trying to rise. Why is he teaming up with a dark snake wizard? Great question, I'll get back to you on that. Currently I am trying to look for a giant flying warship because that's how they decided they would get here. On the Argo 2 that Leo fixed up.

Dumbledore stood next to me with McGonagall and Snape while I stood with the other demigods. "I see it," I shouted pointing at the sky. The giant ship landed. Leo, who was still aboard the ship got out a giant megaphone and spoke into it, "hello, Hogwarts. This is Leo Mcshizzle Valdez speaking-" suddenly Leo stopped talking and Piper got off the ship carrying with her megaphone. "I told him no," she stated walking up to Annabeth. Followed after her was the repair boy in question. "Flaming Valdez is here!" Leo cheered lighting his fists on fire. Then came Frank, Reyna, Hazel, and the cabin counselors for the rest of the 12 Olympians.

Then Chiron wearing his usually tweed jacket but this time with a Camp Half Blood t shirt. Halfway off the ship he stood from his wheelchair. Mr. D trudged behind him mumbling to himself wearing his normal tiger striped Hawaiian shirt carrying a can of Diet Coke. In his other hand he carried a 12 pack box of Diet Coke.

"Hello, young hero's. I'm glad to see you're doing well," Chiron greeted us. "I'm not," Mr. D grumbled. "Glad to see you too Mr. D," I greeted the god. Who just huffed in response. Chiron then walked over to Dumbledore. "Hello, we've spoke before over Iris Messaging. I'm Chiron and this is Mr. D." Chiron shook the old wizards hand. "It's nice to meet you Chiron. I'm Albus Percival Wulfric Brian Dumbledore," "I'm still confused about his name," I whispered to Annabeth who slightly smiled in response.

After introductions Dumbledore lead us into the castle and into the great hall where all the students sat waiting. All the chatter died down when the doors to hall opened. I could see Umbridge at the staff table looking ready to scream. When we made it to the front of the hall Dumbledore began to speak. "As you all are aware, we will be having a Yule dance tomorrow." Cheers echoed throughout the great hall. "Representatives from both Camp Half Blood and New Rome, have arrived to join us. I expect you all to make them feel welcomed during their stay," Dumbledore ended his speech and showed us to the now a lot longer staff table.

At first the staff table was quiet and Umbridge was trying to not be noticed by Mr. D. I was counting down how long it would take till Mr. D turned someone into a dolphin. Annabeth was talking to Piper and Thalia. Reyna was talking to Dumbledore and Chiron. Will was trying to get Nico to eat. Connor was nowhere in sight and that scared me. Then I saw him sneaking out of the great hall with two red heads and I think Travis, who isn't supposed to be here.

Overall dinner was going nicely. Well, Mr. D didn't agree but he doesn't want to be here. Suddenly Chiron started to address the staff table, "as you all know by now I'm Chiron the activities Director at camp. Mr. D is the director of camp Half Blood," Chiron was interrupted by the god saying, "that's all I am now huh, go for a little romp in the woods with Zeus's favorite wood nymph and you're demoted." Ignoring him Chiron continued, "we are very grateful for you all welcoming us to your school. We look forward to a future where we are no longer divided. Praetor Reyna, do you have anything to add?" Reyna stood and said, "yes, thank you Chiron. I speak on behalf of New Rome and I'm sure Frank agrees with me when I say, thank you for welcoming us."

"Jackson, this how you give a speech. Take notes," Clarisse teased from across the table. "'Fight stuff' is an excellent speech. We were heading into battle I was under pressure," I complained. I then heard Will humming the song 'Under Pressure' by David Bowie and Queen.

After dinner the demigods who weren't staying at Hogwarts were showed to empty rooms they'd be staying in. Thalia went back to the Forbidden Forest. Annabeth, Nico, Will, and I went back to Gryffindor Tower.

Harry:

Hermione was ecstatic, which was probably an understatement. She was going on and on about Greek mythology. She was hoping to get a chance to talk to the centaur. "If I could speak to him I could learn so many things," Hermione kept repeating. "Harry mate, I think she's broken," Ron feigned concern. "Ron, the stories say, he knows all about healing, astrology, history, he knows so much." "Well the dance is tomorrow I'm sure one of our new demigod friends could introduce you," Ron suggested. Hermione's face lit up. Nearly shouting she said, "you'd think they'd do that?" "I'm not sure why not," i answered. "Oh my god, I'll get to meet a real historical figure," Hermione squealed.

Thalia:

Before heading to bed Chiron decided to walk with me to the forbidden forest. He said he'd like to meet the centaurs here and I said I'd go with him. I decided to ask him why he brought Mr. D and he pointed out that it'd be good to have an actual Olympian here. Him being the camp director also helps. "Then who's running camp?" I asked my old mentor. "Apollo, volunteered," answered Chiron as we trudged through the forest. I looked at him shocked, "Apollo volunteered?" "He did, I believe there's more to the story but that's what he told me."

We finally found the herd of centaurs. They were looking up at the stars when one said, "Mars is bright tonight." At that Chiron paled a little. Magorian, stepped forward and greeted Chiron. "I've heard of you before, you train demigods and are excellent with astrology. My names Magorian," greeted the centaur. "Hello, I'm Chiron as you already know. I heard there were centaurs living in this forest and wished to meet you. Thalia here offered to come with." "You never told us you knew Chiron," Magorian said. "I didn't train Thalia for long. I did train her friends who are up in the castle though. Of course Thalia and the hunters are always welcomed at camp," Chiron explained. "Even though he didn't train me long I'm still his favorite," I joked. Chiron didn't give an answer instead he just smiled.

After talking Chiron said he needed to head back to the castle. He escorted me to the hunters make shift camp and I decided to ask him about what the centaur said. "Why did you seem worried about mars being bright?" Chiron sighed and looked to be having an internal battle with himself. "If I'm right the centaur that said that is predicting war. As you know Mars is Ares Roman form. Mars the planet is associated with its namesake. The centaurs of this forest are predicting war, that mixed with the current prophecy and current events doesn't look good," Chiron explained a solemn look on his face. "We will talk more in the morning I think it's time for bed," the old centaur said turning to head back to the castle.

Meanwhile at Camp Half Blood:

"Hermes cabin, you are off key try it from the top," Apollo instructed then turned to direct the rest of the campers, "1..2...1...2...ready and," Apollo began directing the camp in 'Walking on Sunshine' Katrina and the Waves.

A/N:

In the first book of Harry Potter the centaur Ronan says "Mars is bright tonight," when Harry was in the forbidden forest with Hagrid. Hagrid told Harry that centaurs don't ever make sense. I actually looked this stuff up to make sure I was remembering correctly.
