Hi guys so this is my first fanfic I hope you like it

Disclaimer: I do not own Percy Jackson

Percy POV

I was standing guard in the chamber that led to a secret room full of riches that even I had not seen, when a group of four people came into the chamber, two girls and two boys, each of them looking about 16, "There are four rules of entering this chamber," I said as the walls made my voice seem deeper than it was, "One, you must fight me in single combat to pass, and only one of you have to win for all of you to pass. Second, when you boys entered I must kill you no matter what unless one of your friends win but the girls may go free. Third, there are no magical powers. Fourth, if one of you breaks the rules I kill all of you and I get to break the rules. Those are the rules, now who's first?"

"I am," said one of the boys.

"What's your name son?" I asked him.

"I'm James" he confidently said.

"Ok James I hope you're ready," I told him.

I uncapped riptide and he pulled out his sword. No one has ever made it past me and I want to keep it like that. When he charged I just stood there and waited. I like to always keep an emotionless face so that I don't seem cocky. When he got to me he slashed left and I blocked it, he slashed right and I blocked it again. He did this several times before realizing that it wasn't working so he slashed up then down while slashing left and right and stabbing repeatedly. I blocked all of them without breaking a sweat when I finally decided to stop messing around and I went on the offensive. I had him to the ground, disarmed, and begging for his life within 3 seconds, when I slashed the vein on his wrist to let him bleed out and die.

"Who's next?" I asked. No one volunteered, "If no one volunteers then I'll pick the boy. No one?" I asked politely, no one volunteered, "Okay now what's your name boy?"

"It's Matt"

"You ready Matt?" I asked.

"Ready as I'll ever be," he said not so confidently.

He drew two imperial gold axes and the sun was just at the right angle from the skylight to where it shined brightly in face, momentarily blinding me. He charged but he was no match for me. I decided to stop playing with my food and just finish them off. I had his neck artery slashed within seconds and he died several seconds later from loss of blood.

"Do you ladies want to fight me or will you leave?" I asked, slightly annoyed that they hadn't left yet.

They whispered privately while I waited for an answer, when one of them spoke up, "Why are you so cruel?" she cry-whispered.

Wait a second! I recognize that voice. I remember it from somewhere, where was it? "Do I know you?" I walked over and took off my hood.

"P-Percy?"

"Annabeth?"

"Why are you here I thought you died?"

"I have a purpose now and if I don't do it I die. It's as simple as that." I told her, "Annabeth you really hurt me so I went to the gods to die, I had nothing left. After my friends left me all I had was you and you cheated on me! With some random guy from the Aphrodite cabin, who I hope is one of the people I just killed! Okay well back on topic are you going to leave or am I going to have to kill you? Oh and who is this?"

"Okay well first yes you killed my boyfriend Matt, this is Thalia, and I am going to fight you." Annabeth told me in her rapid fire talk.

"Okay well are you ready?" I asked

She didn't answer me; she just pulled out her knife and zigzagged her way to me. I uncapped riptide and got into my stance, waiting for her to hit me. When she finally got there she was like a ballerina, jumping up and down around me, slashing every single way imaginable, she even managed to cut me which hasn't happened in 500 years. I finally was able to get a hit in, so I hit her with the flat of my blade making sure not to cut her, and she fell flat on her back. I stepped on her while she struggled to get up and put my sword across her throat, ready to slice her head off, when Thalia got in my way, disarmed me, and got me on the floor at sword point.

"Ah Thalia I thought you were smarter than this," I said in a condescending tone. She looked at me in confusion, "Remember rule number 1? Yes that's the rule that said you must fight me in single combat and you broke that rule by helping Annabeth. Now remember rule number 4? Ah yes my favorite rule, that is the rule that says if one of you break the rules I get to break the rules and you know what that means right? Yes magical powers," I took pride in her shocked face. Right as I finished the sentence water exploded from the walls, turning into sharp, crystal, ice shards pointed right at Thalia's neck. "Walk away now right out that door and no one gets h-," I was interrupted when a knife touched my throat, while I had been reminding Thalia about the rules Annabeth had had time to sneak up behind me.

"Good job Wise Girl," she flinched at the nickname I had given her so long ago, "I take it you'll be bringing me back to camp now by force or will you take the riches and leave and then take me back to camp by force?" I said icily. Someone beat me and now my job is over.

"I don't know, let me think about it," she said sarcastically, "The only reason we were here was to fetch celestial bronze and imperial gold for the two camps, but you're an added bonus," I didn't like the way she said bonus.

"Well then hurry it up; I've got nothing better to do. You guys beat me and in my contract it said I had to work for eternity unless someone beat me, I swear it on the River Styx," we heard thunder boom even though we were 300 ft. under ground.

When we got back to camp with all of the riches, it took almost a week to load it up might I add, everybody stared in awe at the riches and at me. I had my hood on, but I guess the campers didn't expect a prisoner of war. I also noticed that all of the major gods were there and only a handful of them knew of my existence and where I had been. As I half dragged half walked along I noticed some of my old friends from 500 years ago. I saw Nico, Grover, Juniper, Tyson, Mrs. O'Leary, somehow Zoe and Bianca were there too, I saw Will Solace, the Stoll brothers, Kadie Gartner, Piper, Leo, Jason, Frank, Hazel, and Reyna. I remembered that Piper, Leo, Jason, Frank, and Hazel all moved to Camp Jupiter, so I guess they were here for the summer solstice. Somehow all of them are still alive, so I guess they had gotten immortality for being such great hero's. When we got into the middle of all of the demigods, and I mean all of them. The romans were here also to take whatever imperial gold Annabeth and Thalia found. When we got to the middle, Chiron, Lupa, and the gods all came over.

"Where is Matt and James?" asked Chiron in a saddened voice.

"The guardian of the chamber killed them but Thalia and I captured him." Annabeth said quietly.

"Well dears you did the two camps a great favor finding all of this treasure," said Zeus, "Well, now who is this prisoner?"

"I think a lot of you might know him actually," she said while unmasking me. I heard a collective gasp as all of them recognized me, from either stories or from knowing me.

"Yeah, yeah it's me. Do you guys need anything or can I go?" I asked in quite a rude tone, still mad at them for what they did, even though the new campers didn't have anything to do with it. I turned my head to left exactly 23 degrees and saw the person who started this, the person who ruined my life so long ago. Isaac. Isaac was a good kid before he started getting arrogant and cocky. He is a son of Mars, not Ares but Mars. He decided to come to Camp Half-Blood instead of going to Camp Jupiter where he belonged. He was modest until he beat Clarisse in a fight. That's when things got ugly. He went around challenging all of the newbies and the small kids always winning and somehow making a name for himself. One day, a Hydra attacked the camp. Of course I was the one who battled it since I was the most experienced, but when I was about to deal the finishing blow Isaac comes over and stabs it first, pushing me to the ground and making it seem like he did all of the work. Everyone started hating me after that, saying that I'm a coward and a loser. I just ignored it and then Isaac started making snide comment about me and all I had left were my good friends. But then he challenged me to a duel and I mercilessly beat the crap out of him keeping him within an inch of his life. Several of my friends left me; only my good friends remained like Nico, Grover, Annabeth, Frank, and Hazel. I cherished them but then Isaac stole and burned several of their most cherished items and blamed it on me, and the thing is they believed him! That's when I went to the gods to die but they gave me the purpose of guarding their most sacred treasure. I took pride in that fact that many people tried to beat me but none of them could, until now. When I saw Isaac I was filled with such rage that I broke my bonds and lunged to him, grabbing his throat and throwing him to the ground and putting a knife to his throat ready to kill him. I didn't for some reason I realized it was because everyone was watching me and I didn't want to seem cruel, so I let him go, taking pride in the terrified expression on his face.

"Well now Percy it's good to have you back," said Zeus

"It's almost good to be back Lord Zeus," I said while bowing to him, "Lord Zeus with all due respect to this camp and its people, I just can't stay here, I need a new purpose and I would like to ask if you could grant me one."

"Well Percy as it seems you just got back I'll have to think of one, for now you will stay here at camp," he said politely.

"Yes Lord Zeus," the Olympians teleported away and left me with the camp.

"Welcome back Percy, we left your cabin just the way it was 500 years ago when you left," Chiron said, "It seems you remember Isaac," he said the name with disgust, "By the way I give you permission to kill him in a duel," he whispered in my ear so only I could hear it.

"Isaac, I challenge you to a duel, no magical powers or items of any kind but any weapon is allowed, do you accept?" I asked him.

"You're going down Jackson," he said trying to sound brave, but I could hear the fear in his voice. I walked to the arena all by myself, my "friends" staying back trying to run up to me and hug me. When we got the arena, everyone was already in their seats so me and Isaac walked to separate sides of the arena and got ready. I uncapped Riptide and Isaac pulled a giant hammer.

"LET THE BATTLE BEGIN!"
