Chapter 1

POV: Percy

Wow, another adventure with Annabeth is just what I want, and that's what I get. It is why I am currently running alongside Annabeth, chasing a "giant magical puppy" who had been raiding the camp for the past couple of weeks. It's been looting food and crashing the barracks. We raced along the green grass and flew past the tall trees and the prickly bushes. Annabeth had her usual blond hair racing along behind me. The gray streak of hair that we had shared by holding up the sky had faded over the years but dang she looked pretty! We ran along in silence, chasing the huge bulldog.

I saw a green field and we burst into the clearing from a hedge of bushes. We burst out and drew our weapons. My deadly looking sword, Riptide, shined brightly in the basking sun. I grinned as I saw Annabeth quickly draw her knife. I turned in front of us and found that the had puppy disappeared into the other side of the forest. I cursed under my breath in frustration.

I suddenly had a flashback of when I was in Dr. Boring's class for an essay and my hellhound, Mrs. O'leary, had come bounding in and everyone thought she was a giant poodle. That made me thought of the adventure that came after. That made me think of Bob. And that made me sad because I remembered his sacrifice.

Then I heard a faint rustling noise in all the bushes around us. I instinctively went back to back with my girlfriend. The noise was getting louder and closer. I shifted nervously in my stance. I mean, I had fought plenty of monsters before, but this sounded like tons and tons were coming our way.

All of a sudden, four humanlike figures dashed out of the bushes and we instinctively started slashing and hacking at the party crashers. They started fighting back. Then I recognized a brilliant flash of bright, blond hair and I laughed. Like, really loudly. Everyone stopped and they chuckled as well. It was some people we recognized.

"Well, hello old friends. Nice to see you Jason, Piper, Frank and Hazel." I said. Everyone chuckled.

"Hades, it's nice to see you Percy. You too Annabeth." Jason said as he nodded at Annabeth in recognition. Piper smiled and bowed mockingly. "Well, all of us here together at this exact same spot. This can't be a coincidence." Suddenly, another rustling in the bushes made us all draw our weapons and stand in a tight circle back to back. We were familiar with each other and everything was pure instinct. Figures burst out of the bushes and I recognized them.

"Wait! Hold up. Annabeth and I know these guys. Just, stop what you're doing." I shouted. All of them seemed confused. Annabeth just grinned.

"Nice to see you cousin. Sam. And… Alex, right?" Annabeth asked as she accordingly pointed at the new guests.

"Yeah. This is a bit awkward." she said. Or he. This whole gender fluid thing still confused me a ton.

"Wait, who are these guys?" Frank asked.

"Frank, Hazel, Piper, Jason, these are our friends. Magnus, Sam, and Alex. We told them about you guys because they are kind of from the Norse world. Like, Odin, Loki, Thor." Annabeth explain as she indicated them one by one. "Magnus is a demigod, Alex is also a demigod, she or he is gender fluid and transgender. And Sam is a Valkyrie. She can fly and all those things." Our friends looked dumbfounded.

"So, why are you guys here?" I asked everyone.

"Well, we are here because we were chasing down Buford again, we called Frank and Hazel. Leo was working on something in the newly built Argo III" Jason answered

"Who's Buford, wait, don't answer that. We were chasing down an ice giant that had intel on Loki." Magnus replied.

"Yeah, we were chasing down a magical puppy." I said.

"A magical puppy? Wow that definitely sounds like a load of rubbish." A voice said behind us. We all whipped around. It was more familiar friends.

"Well, Carter and Sadie Kane. What the heck are you doing here?" The others exclaimed in recognition who these guys were. They smiled and they all shook hands.

"We were actually here because we located a very large magical source here and we came to check it out." Carter said.

"All of us here. Greek, Roman, Norse, and Egyptian mythology. All of us here at the exact same time. I wonder which god is toying with us?" Annabeth said. A huge shadow suddenly hovered over us. I looked up in wonder and saw a huge, floating, wooden podium.

"Not god, gods." a mysterious voice said. "Going up!" we turned around and saw a ginormous man in a brown trench coat and a fedora take a device out of his pocket and push a button. The platform beneath us shook and rumbled, then, we went up.

"Oh gods! What the heck is-" My voice cracked as we went up, and up, until no one at Camp Half-Blood could see us through the thick barrier of clouds.
