Background: after the war with Gaea Jason stayed at camp half blood. Hazel and frank went back to camp Jupiter. Everyone else is at camp half-blood. Frank became praetor in Jason and Percy's absence. The two camps were at peace after Nico and Reyna showed up with the Athena parthentos. No one died in the giant war besides monsters and Gaea it back at sleep. Son of Sobek happened between PJO and HOO. For this I'm assuming son of Sobek happened a few days before Percy disappeared. He told no one of meeting carter. He did mention that some random kid helped him fight but nothing more. Carter on the other had did tell Sadie about meeting a kid and being extremely curious. He told her his name. Traveling from camp Jupiter to Greece took a month meaning when Percy got to camp he was gone for a total of a little over 9 months. The beginning of this is a few days before the start of school. Staff of Serapis did not happen as I have not read it.

PERCY POV:

I couldn't believe that we had defeated Gaea and now I'm just going back to school like I didn't miss a whole year of my life. Anyways its five days before the start of school so some of the demigods have already left by now depending on where their families live or where they go to school. I was in the training arena sparing with Clarisse.

"Seaweed brain! Chiron wants to see us in the big house" Annabeth, my girlfriend, called.

Clarisse and I stopped fighting and I followed Annabeth to the big house. "So what does Chiron want?"

"No clue, but he wanted you, me, Jason, drew, lacy, piper, and Leo. I think it might have something to do with school."

"Great I just love school can't wait to get back" I said sarcastically.

"I'm sure it'll be nothing big."

"Come-on of course it's big if he's sending part of the seven."

We walked into the big house and found we were the last to arrive.

"Good now we can get started" said chino.

"What did you call us here for? Asked Jason.

"I think that drew and lacy could tell this better than I, go ahead tell them"

Drew started "Well some strange things have been happening at our school last year"

"Like what?" asked Leo.

"Well the first thing happened shortly before the fall equinox at a dance. Well I guess before this I should give you some build up background to this. Lacy and I go to the Brooklyn Academy for the Gifted or BAG for short. Anyways last year there was a large group of students who came to the school and all hang out with each other all the time which is weird for transfer students. Fast-forward to the fall dance and I guess you could say the leader of the group, Sadie, brought her brother to the dance. Then while we were talking this guy comes up and takes her to dance. Now that might not seem weird in its self but he had this very strange aura of power about him. Then during a slow dance everyone passes out, very strange, and lacy would you like to tell everyone what you heard during this"

"sure so I didn't fully pass out I fell to the ground like everyone else but I didn't pass out it just felt like all the energy was sucked out of me but I was still conscious. I heard Sadie talking to some people I never heard of before. They were talking to someone named shoe? And talking about gods. I never heard of a god named shoe have any of you?"

Everyone murmured in agreement "no"

"Then this is where it gets even weirder if that's possible. Apparently Shu is an air goddess and tried to separate Sadie and her friend and said names like Isis and Horus. I did research and those are Egyptian gods. Then she mentioned something about bringing some Russian from St. Petersburg. Then the air pressure rose and I passed out fully. But when I woke up Sadie was talking to who I assume was the Russian with her brother. I tried to get closer but the teachers were pushing us away. Other things happened throughout the year but nothing as big"

"That is why we are sending all of you to investigate and try to figure out what is going on" Chiron stated

"Wait, lacy said something about Egyptian gods do they exits too Chiron?" asked Jason.

"I honestly don't know, remember Greece was after Egypt Rome after Greece. I knew about the romans but they didn't know about us it could be the same situation with Egypt or not I have no idea the gods never once mentioned Egyptian gods to me."

"So let me get this straight your sending us with lacy and drew to investigate possible Egyptians at BAG?" I said

"Yes pretty much" Chiron replied.
