A/N: Wow surprised at how popular this story is. Hope you enjoy chapter four.

Camp Half-blood

Percy stood in the middle of the arena, looking around. He tilted his head up to see the small symbol above his head. So that's what they are all looking at. Percy then noticed Chiron walk into the arena, at seeing the symbol he immediately bowed, and stated in a deep voice, with hint of nervousness.

"All hail Percy Jackson, Son of Chaos"

Percy ignored all the stares he was getting and just carried on walking out of the arena. He had just got outside, when he noticed something appear in the sky. A dark portal opened right in the middle of the other cabins. Percy grinned, his dad sure knew how to show off. Out of the portal a huge structure began to descend to the ground. Percy wasn't the only watching his new cabin appear, the whole camp was in awe. Percy felt the earth shake a little as the huge structure landed. He noticed it was a lot bigger the cabin one. Percy knew this would piss Zeus right off, as on cue, thunder rumbled across the sky. Percy ignored it and carried on walking towards his new cabin. Where all the other cabins were just average, he found that his was much more advanced. For example his cabin door, slid open, there was no handles or lock. Once inside Percy noticed the cabin had it's own bathroom facilities, it's own private lounge, with a T.V and everything. Percy could see his dad had gone all out. He then walked into his bedroom, where he found a nice big double bed, no small wooden cot like he had to sleep on in cabin three. He noticed a letter and a small pen on the bed.

Dear Son

I hope you like your new cabin. The main door will only open to those who contain my blood, which means only you have access to it. If you do managed to make any new friends then you can key them into the door manually. However the act would require a drop of their blood. Now on to the main facilities. The lounge is equiped with everything you need. TV, game consoles, DvD player, you name it. Also the bookcase in the lounge doubles as a secret door which opens up into your very own private gym. I know how you liked to keep in shape in the last time-line and decided to add it in for you. The kitchen area, is mainly so you can prepare yourself some lite snacks and stuff. The fridge will refill every week, don't worry about cost, this is all being taken care of by me. Now I know you miss your old sword Riptide, so I decided to give you something better. This Pen works similar to how your last sword worked. However what make this weapon unique is that it contains my essence. This sword as the power to kill any immortal being. On the hilt is a small button, press this and the blade will be filled with my energy allowing you to kill, an immortal, with out the button it just ask like a normal sword, with the added bonus of it being unbreakable, it also has the ability to return to you, just like Riptide use too.

I wish you all the best in your quest son, and know that I am watching you always

Chaos.

Percy placed the letter on his side and the picked up the small pen, he clicked, it and watched as it glowed before revealing a sword. Percy spotted the small button on it and pressed it. When he did he noticed a purple streak of energy run up the middle of the blade, before surrounding the blade in a ghostly purple aura. Percy swung the sword left and right, and found out that it was just the right weight for him to wield efficiently. He clicked the bottom of the sword and watched as it turned back into a pen. He suddenly heard a loud knock on his door. Placing the pen back in his pocket, he walked out of his room and opened the door. He growled to find his brother standing there.

"What do you want?"

Mark, glared at his brother. Before pushing past him and walking into the cabin. Percy grabbed his shirt and yanked him outside.

"Hey, What did you do that for? I thought this cabin was for both of us?"

Percy grinned. "Really, well I didn't see a symbol appear above your head in the arena. This cabin is only for those who have the blood of chaos in their veins. This means only I'm allowed in here, unless I invite anyone in. You are certainly not welcome. I heard that all newbie sleep in the Hermes cabin, which is the big one over there."

Marked turned to look at Percy, eyebrows raised. "How the hell do you know that?"

Percy kicked himself for being so stupid. He had forgotten that he wasn't suppose to know where everything was. He had to come up with something pretty fast.

"I overheard a few of the other camper mention it. So why don't you go introduce yourself to everyone and leave me alone."

Percy then shut the doors in his brother face, before crashing down on the sofa, and switching on the T.V God life was good.

Olympus

All the Gods were in uproar about the Percy being the son of Chaos. Never in history had Chaos ever had a demigod. So why now? Many of the Olympians were wondering if it had to do with the great prophecy, involving a demigod saving or destroying Olympus. One Goddess though was rather confused about the whole Percy thing and that was Aphrodite. As the Goddess of love she could sense the emotions in mortals and their feeling towards each other. This is what allowed her to match people up, however what was confusing for her was that Percy was having feeling for someone he had never met before. The girl in question was Thalia the daughter of Zeus, she had sacrificed herself to protect her friends, Zeus had then saved her from death by turning her into a tree to guard Camp half-blood. The boy had never met her, so how could he have such strong feeling for her. Aphrodite then thought about everything else that had happened. Percy had been able to use is Godly powers on command, not only that but he had the body of someone who looked like that had fought for years. On top all this he was gifted with the blade. Something just wasn't right. However she decided to keep everything to herself for now and just watch him closely.

Zeus was sitting in his throne, in complete silence, watching his fellow Olympians argue. He himself had been shocked in learning who Percy Godly parent was. Chaos had been the one to help them defeat the Titans, after he had imprisoned his own children simply known as the Primordial Gods. He had then made Zeus King of the other Gods. He had then provided him a female companion, so that he could create a new Pantheon of the Gods. Once the council was full, Chaos had then had given them each a domain. He and his two brothers would be known as the big three, as the would rule over the biggest domains, being the sky, sea and underworld. The rest of the God and Goddess were giving smaller domains, that reflected on their personal traits. Zeus noticed his brother in deep thought.

"What is wrong Poseidon, you seem lost?"

Poseidon turned to his brother, he himself was confused about the whole Percy enigma. When he had seduced Sally Jackson, she had not mentioned that she already had a child. In fact he couldn't remember even hearing or seeing a Percy when they had made love in her apartment, so where had he been at that time? The next thing that was troubling him was Mark. He was only a year younger then Percy which would have meant that Sally would have just given birth to Percy before she had slept with him. Things just didn't add up. Suddenly he was pulled from his thought by a small portal opening up in the middle of the throne room. Many of the Gods had their weapons ready, just in case it was a threat. However they noticed their weapon suddenly vanished and a figure step out of the portal.

Zeus shifted uncomfortably in his throne. He perfectly knew who this was. He noticed his brother;s eye widened at the sight of the figure. Zeus then coughed before standing from his throne.

"Lord Chaos, this is a unexpected visit, may I ask what brings you here?"

Chaos threw off his robe and stood in his traditional black suite, his golden eyes looking around the entire council. He then raised his hand and using is power forced Zeus to fly back into his throne, preventing from moving.

"Why I am here is none of your concern Zeus. I come here with warning. Any of you think about harming my son then I will wipe you from existence, do I make my self clear? As for you Poseidon, If you must know Percy was adopted by Sally, he himself doesn't even know. You see I seduced her best friend, and unfortunately she died giving birth to Percy. His Godly powers were too much for a mortal to bare. It was then her best friend Sally Jackson adopted him, promising to raise him us her son."

Chaos knew It wasn't the truth, but there were just to many things that didn't make sense about Percy sudden appearance. It seems his bluff had worked though as Poseidon immediately stopped thinking and accepted his explanation. Chaos noticed Zeus was trying to move, he lowered his hand allowing the King of Gods to move once more.

"Very well Lord Chaos that explains his sudden appearance, but what it doesn't explain his how he can use a sword so well, not to mention use his powers at will."

Chaos growled. "Percy is naturally gifted with the sword, it was one of my gifts to him, also Percy as the power to control all the elements and again was gifted with that knowledge by myself."

"But why now Lord Chaos? You have never had a demigod child before. Why now?"

Chaos turned is attention to the Goddess who had just spoken.

"The reason Lady Athena, is because I have watched how each and everyone of you have abused the power I gave you. The world is tearing itself apart down there and all you lot can do is sit up here ignoring it. Is it no wonder mortals have stopped worshipping you? The only mortals who still worship you are your own children, who are sent on quest after quest just for your own personal amusement. Well enough is enough, Percy is going to be your judge. He will decide if Olympus is to stand or if it is too fall.

Zeus eyes widened. "So he is the child of the Prophecy, but that can't be he is not a child of the big three."

Chaos grinned. "He may not be the child of the prophecy Zeus, but he will still be your judge and executioner, Don't forget he has all my powers even those to wipe a God from existence. You have been warned Olympians change your ways or suffer at the hands of my son."

Chaos then vanished from the throne room, causing the room to erupt in arguments. Many of the Gods were panicking. A child had been born that had the power to destroy their very existence, and the problem was they were powerless to stop it.

Chaos Cabin

Percy was sitting in his cabin when he heard the camp horn sound. He rubbed his hands, he had been looking forward to this. It was time for capture the flag. Percy was going to make sure instead of Mark facing Annabeth, then he would face him instead. Percy whistled before grabbing his sword from his bedroom and walking out of his cabin onto the big green. He noticed all the other camper were assembled already. He pushed his way towards the front where smirked to see a glaring Luke looking at him. Percy ignored the blonde pounce and listened to Chiron.

"As you know, at the beginning of each summer, we start off with a friendly game of capture the flag. As usual the teams will be cabin Athena, Ares, Apollo vs Hermes, Aphrodite, Demeter. This years captains are Luke Castellan from Cabin Hermes and Annabeth Chase from cabin Athena. Percy as you have been claimed you are allowed to choose who side you wish to join."

Percy grinned. "I will choose the side of Athena, Ares and Apollo." Percy heard a huge cheers from the Ares cabin. Clearly they admired his skill in battle.

Chiron nodded. "Very well you will have 30 minutes to come up with a strategy and battle plan. remember your flag must be in plain sight, and on the ground. When I sound the horn, the game will begin."

In the woods

Percy yawned as Annabeth, explained the battle plan. He didn't care so much for it. As long as he got to make a fool out of his brother then he was happy.

"Ok everyone that's the plan. I will stay out of sight to guard the flag."

Percy raised his hand. "Excuse me, but if you are the leader, shouldn't you be leading the attack, instead of hiding away. Why don't you allow me to guard the flag. After all I did beat Luke, the best sword fighter in this camp, so it seems only logical that the strongest should guard the flag."

Percy gulped as he noticed those stormy grey eyes look at him. Even in this time-line they were scary.

"Fine, Percy we will both guard the flag. The rest of you move out."

Percy groaned. This not what he wanted. Talking to Annabeth was bad enough, but being alone with her. He noticed she was still glaring at him.

"What's the problem Percy, got a problem with me staying behind? If you want to know the real reason is I don't trust you. In fact I wouldn't put it past you to hand over the flag to your brother without a fight."

Percy grinned. Why would i want to do that? I can't stand the little brat, but if you insist the fine, but know this, if Mark does reach the flag first. He's mine understand?"

Annabeth carried on staring at him before nodding. "Fine, and if it is anyone else then I will deal with them deal."

Percy smirked "Deal" Percy then heard the horn blow. "Its show time."

Percy sat in one of the tree next to Annabeth, watching the flag. So far no one had made an attempt on it. He was feeling rather a little uncomfortable being this close to Annabeth, what didn't help was she kept glancing at him now and again.

"So you're the son of chaos?"

Percy just shrugged. "Guess so what of it "

Annabeth locked eyes with him. "So what, so what. Chaos is more powerful then all the Gods of Olympus, its unheard of him to have a child. Especially a demigod. He was the one who granted the Olympians their powers in the first place."

Percy was looking for a way out of this conversation. After all he didn't want to risk getting to close to Annabeth. It seems the fates were fucking with his head once more. It was then he noticed his brother kneeling by the small creek to get a drink. Percy grinned as his eyes locked with their flag. He waited till Mark was about to grab it before jumping down starling him.

"Well this is a surprise. If you want that flag, then you will have to go through me brother."

Percy watched Mark growl before coming towards him with his sword. Percy parried every strike with ease. Had he been this bad when he first fought Annabeth? Soon he was growing tired and decided to end it. He quickly slashed his blade right and left, causing a few cuts on his brother cheek and arm. He then tripped him up, forcing to him to fall face first on the gravel floor. He heard the cheers behind him and waited he knew it wasn't over. After all this is where Percy had learnt who he was. Like before he heard the gasps and the looked at the shocked expression on everyone faces as they watched his brother wounds heal using the water. He noticed his brother seemed more confident and soon were taking down the other demigods who intercepted him. Soon it was just him and Mark.

Percy grinned. "Just because you found out you that you're the son of Poseidon, doesn't mean you can beat me brother. Or did you forget my father was the one who gifted the Olympian with their power in the first place. Just turn away now, unless you want me to hurt you."

Percy grinned as his brother dropped his sword, maybe he wasn't such an idiot after all, his eyes then widened as he noticed his brother focusing, his eyes looked to the small creek and could see the small waves forming.

"So that's your game is it. Fine with me."

Percy then caused lightning to appear in his hands, before his brother could summon the wall of water, Percy hit him with two arcs of electricity, causing him to fall to the floor.

"Lesson one brother, never try to use water against someone who can use the element of electricity, you will always lose."

Percy then kicked him in the ribs forcing him to double over. He heard the shouts coming from the other side of the creek and looked up to see three Ares campers holding the flag above their head. They had won. Percy stepped over his brother, and immediately noticed Annabeth kneel next to his brother to see if he was ok.

Percy grinned. "So it begins!"

A/N: That's the end of Chapter four. Has you have likely guessed. it will be Percy, Mark and Annabeth chosen to find Zeus masterbolt.
