A/N: Ok, so Poseidon heard about Hecate's pet world and decided to go down to earth for a few years as someone else and he was called James Potter. 

A/N: This is me again, sorry. I'm not updating from next Tuesday (week from tomorrow) until April 7th maybe. Here's something to laugh about, yesterday I was over at my friends house and we were looking at memes and stuff and there was this headcanon about the lion king and instead of saying Mufasa I said Mafusa and I laughed so hard

Percy's POV

I woke up panting, I'd had another nightmare. I'd been so used to not having them because Hogwarts magic interferes with them. The sun was just barely over the horizon, so I decided to go for a run. In my animagus form of course, I made it all the way to a small lake in the woods next to the Weasley's house. Ever since becoming an animagus I'd become faster, and Harry, Ron and Hermione had changed too. Ron and Harry were also faster and Hermione, if possible, was smarter. I finally got back to The Burrow, I changed back and ran inside. It looked like everybody was still asleep, so I went upstairs to Ron's room where Harry and I were staying, Hermione was staying with Ginny, I shook Harry awake.

"C'mon Harry, get up. I'm bored, C'mon Harry!" I whisper yelled in his ear. He groaned,

"What time is it?" he asked,

"Time for you to get a watch." I said back, Harry sat up,

'I had this dream, it was weird. There was this guy with gold eyes, and he was talking to Voldemort about something, I don't know what and his weapon was this scythe that was made of bronze and iron.' Harry finished recounting his dream to me when Mrs. Weasley shouted that breakfast was ready. 

'Harry, those dreams are normal but they usually mean something. So be careful, you don't get them at Hogwarts because magical interference or something. I'll explain later, c'mon Harry, breakfast's ready and I'm hungry.' I said, I started pulling him down the stairs with Ron.

"You're always hungry." Ron said,

"So are you." " pointed out "ONWARDS!" I said, running down the stairs, I was the first person to breakfast, then it was Ron, then Fred and George then Ginny and Hermione. (Fred and George came for Christmas) It was lucky that Mrs. Weasley could make so much food because between Ron, the twins and myself there was almost no food left. Finally it was time to go back to school. I had forgotten that we were going back today, we stepped into the fireplace and said "HOGWARTS!" and disappeared in green flames. I tumbled out of the chimney covered in soot, Harry and Hermione followed. I dusted myself off the best I could and started walking to the common room,

"C'mon you guys, we need to get to the common room, McGonagall said that there would be the first quidditch game schedule and I wanna see!" I whined,

"We're coming." Hermione said, Harry, Ron and I burst into a full sprint and raced to the common room. It was a close call because of our enhanced animagus speed but I'm pretty sure that I won. We ran to the bulletin board and there was a new piece of paper there, 

"Quidditch game schedule:" Harry read "Games are on January fifth, the eleventh, and the twentieth. Than there are the finals." (I know quidditch doesn't go into January but I'm doing that because I haven't had them play any games yet)

"Cool. Let's get the Quidditch Cup!" I cheered.

Training became harder and harder, finally it was our first game. We stepped out onto the field, the crowd was roaring in the stands, the Slytherins were booing but still. We were playing Hufflepuff, we all mounted our brooms and took off. Luna Lovegood was commenting today, she was weird in a good way. She didn't follow the game well but she was funny, saying things like 

"Oh and Ginny Weasley has the quaffle, she very nice, she passes to the new Chaser Percy Jackson, he is very smart. I don't know why he's in Gryffindor..." she got off topic very easily. I should check to see if she's a demigod. Harry suddenly started to dive, the Hufflepuff Seeker followed him, thinking he had seen the snitch. Harry pulled up just before he hit the ground, the other Seeker plummeted face-first into the dirt. He got back up after ten minutes and took off, much to Hufflepuff's delight. Harry flew into the other side of the pitch while I scored another goal, a bludger rushed by my face, I swerved to avoid it when the Slytherin Beater whacked it towards me again, this time I wasn't quick enough and it hit my lower arm. I heard a crack, it was broken. I'd get it fixed after the match, it wasn't so bad that I had to leave. I kept playing, Harry suddenly started diving, again. He'd seen the snitch! The crowd held their breath, Harry and the Hufflepuff Seeker were neck and neck, Harry pulled ahead, he reached out his arm and that's the last thing I remember.

~1 hour later

I was in a cave of some sort, there was a forge and a table of sorts with a kind of map on it. I walked over to it but I was stuck,

"Well well. We've finally caught him." a familiar voice said, I looked into the red eyes of an old enemy.

"Voldemort." I hissed, 

"Perseus Jackson, nice to finally meet you. Killing you shall be easy. You have the same face of Potter."

"So?" I tried to get the shackles off my hands that were binding me to the floor. They appeared to be made of celestial bronze and imperial gold alloy. It was useless. 

"Good to see you again, my old friend," the voice spat out the word like it was acid. "It is good to see you, Perseus Jackson." an all too familiar pair of golden eyes appeared in the shadows. 

"You," I tried scrambling back, but it only made my broken arm scream in pain. "How did you come back, you weren't supposed to come back for another century."

"Ahh, young Perseus, I was never dead. You should know that, I took the souls of the recently dead and entrapped them to do my bidding. I was soon able to find a host, do you not recognize this young man?" I took a closer look at Kronos's host, I gasped in realization, I'd never met the host, but I'd seen his face in old photos. Grinning and laughing with his friends,

"Sirius?"
