Takes place after The Last Olympian (different ending). Percy is granted immortality, along with Clarisse, Annabeth, Chris, the Stolls, Katie Gardener, Grover, Juniper, and Nico. New child of Poseidon enters equation, and Percy is forgotten. Will he become the assassin that Chaos always needed?

The Beginning

Percy POV:

I laughed at a joke that Grover was telling me. It wasn't that funny, but he was trying his best. I honestly think that if he doesn't try, then he will be the funniest person in the world. Nico and Thalia were walking together. Most people expected Thalia to quit the Hunt in order to be with Nico, but it turns out that they are just amazing friends. And Nico said that there was someone else out there. Somewhere in the large expanse that was Ouranus. Sometimes I wondered if he could see the future or something, but sometimes, I wondered if he was so blind he couldn't see the present, so I figured it wasn't true.

Thalia was walking with us, but something seemed to e troubling her.

"Thals, what's up?" Nico asks.

"Nothing. Umm, guys, maybe we should head down to the, uhh, lake!" She said the word lake as if she'd just come up with an answer to a humongous test, and that she seemed proud.

Something was wrong. We were heading down to see Annabeth, and I had told them all that I was going to ask her to come to Montauk with me. There, I had asked Athena and Poseidon to come. Before all of that, I had made Poseidon swallow his pride (which is still big, but there's a reason that Athena's children's fatal flaws are deadly pride), and I knew that, when it came to love, Poseidon understood, and would do whatever it took to obtain true love. Sometimes, he was as bad as Lady Aphrodite. When Poseidon apologized to Athena, she looked very surprised, but she forgave him.

I have now convinced the two of them to come to Montauk while we were there, and have them show Annabeth that their rivalry was over, so it was okay with them if we could date. I knew her mother's consent meant a lot to Annabeth, so I thought that she would love it. Little did I know that today would crush all of my dream of ever being with her.

Thalia POV:

Annabeth had told me that she needed some time with her and an Aphrodite guy. At first, I thought no way, but now I heard them giggling, and I knew that I had to keep Percy away from there. Annabeth had been very confused lately, because Luke had just died, and she still didn't know in which way she loved him, and I knew that she needed some down time. I quickly told Percy to run and go get Annabeth flowers.

"She hates flowers. She says that they make her feel girly…" Damn. He was right. Oh well. It was a good thing I heard the giggles first, but that was probably because I was looking for them.

"Trust me Percy. I have a plan." So he went to go get some flowers. I followed the giggles, and found Annabeth kissing Drake, an Aphrodite guy. I pulled them away from each other, and threw him into the lake.

"Annabeth, what on Gaea do you think you're doing?" I yelled at her. She seemed un-phased.

"You know Thalia, I'm tired of having you boss me around all the time. You know what? You aren't my mom, or my sister, or anything to me anymore! Just stay out of my life, all right?" She said calmly. I was too shocked to do anything. Did she just say that she was leaving me behind? Even after she had just become immortal with me, she still decides to do this to me? Well, I was already immortal, but still. We could have been awesome together!

Then, I figured it out. Annabeth ahd just been through a war, saw someone she thought she was in love with die, only to find out she loved him like a brother, become immortal, be in a relationship that her mother forbids, and her dad just died from a heart attack. I could see why she broke. The person I was talking to was not Annabeth. This was her alter ego.

"Now if you don't mind, I will be getting back to my make-out session, because Drake doesn't care how mean I am. He sees me for my beauty."

I heard Percy footsteps a couple of minutes later while I was guarding Annabeth's hiding place.

"Percy, it might no be the best idea to go in there. Annabeth's … not herself."

He frowned, but then he heard the giggles. I silently cursed myself. He looked at me wide-eyed.

Percy POV:

She wouldn't, right? I mean, we were in love. She just kissed me in the lake not yesterday. Yea, we might have been taking it a little quickly, but I loved her since I was in the Cyclops cave with her. And she told me that she was positive that she loved me since she kissed me on Mount Saint Helens. I walked into the little clearing with flowers in hand, and I saw her and some Aphrodite kid with he. And when I say 'with,' I don't mean hanging out. When Annabeth say me, I saw something behind her grey eyes burst though, as if there had been something suppressing another.

Annabeth POV:

My alter ego was out, and I did not like it. I had just finished yelling at Thalia, and that brought the original me out a little, but then I saw Percy with the flowers in his hand. I couldn't believe what was happening. I didn't have a shirt on, and Drake was on me. I pushed him off, grabbed my shirt really quick, and ran over to give Percy a hug. There were tears rolling down my cheek as I realized what had almost happened. Luckily, Percy had anchored me to the Earth. When I got to him and hugged him, he shoved me so hard, that when I fell, I hit the funny bone in my knee. Damn! Each time it just hurts even more! And it was not funny.

Percy—" I started, but he just held up a finger, walked over to Drake, and punch him in the face so hard. I saw Percy put all his shock, anger, fear, hurt, and every possible emotion (except for obviously the good ones) as he structured his punch perfectly, having the rotation in his fist match the distance between him and his opponent., so when he punch, not only would Drake have an immortal sock him in the face, but his face would feel like it was being drilled. And let me tell you, if Percy is driving that drill, you do not want to stand in the way. As the punch finally met Drake, his necked spun, snapping by the sounds of it, and his entire body was flung backwards like it was a ragdoll. He landed a solid twenty feet away.

"Percy!" I yelled at him. Sure I understood his anger, but he hasn't even let me explain, so naturally, the first thing he thinks up is, 'Oh! I should punch that person!'

He laughed bitterly. "You are yelling at me?" "Well, you did just punch someone so hard they may be in the infirmary for a couple of weeks!" "Annabeth. How could you?" "Percy. It's not what it looked like. That wasn't me." I sated the fact as if it were the most obvious thing in the world. Did he seriously think that I would cheat on him? No, it must have been something else.

"How could I what?" That infuriated him. "Annabeth, you cheated on me!" Okay, maybe it was that. "And the only excuse you can come up with is that it wasn't you? Annabeth, you are evil!" Okay. Now that struck deep.

Percy POV:

I turned and ran, dropping the flowers, with tears cascading down my cheeks. Once I was deep enough into the woods that I didn't think she would follow, I was proven wrong for the second time that day. Annabeth showed up, and saw me crying. Dread filled me.

She sat down next to me, and tried to put her arm around me comfortingly, telling me to let her explain. Explain? What I saw was pretty self-explanatory.

"Percy, who you saw wasn't me. Under all the stress, I snapped, and my alter ego came out. Believe me Percy, I would never do anything to hurt you." Did she think that she was under stress?

"Annabeth, do you not think that I'm under stress too? For about half a year, I thought I was going to do everything I could do for the universe, but in the end have my soul reaped by my sword. Now that merely weakened my spirits, but I was determined to at least try not to show it. Then, I thought that you were in love with someone else, and that we could never be. I had to fight over three titans, one of which almost killed Chiron. Then, when I was either to give a titan your dagger, or try to kill him myself, I thought that if I gave it to him, then he could kill Kronos, but if I did, then we might also find out that it was a trick, and that we're screwed. Don't think that it was just me that was screwed. Remember that my fatal flaw is loyalty, so when I realized that everyone I loved was going to die I almost broke. The only thing keeping me here was you, Annabeth. I trusted you. Eventually, I would have wanted to marry you! But now I realize why my fatal flaw is fatal. I can't trust my friends. Now, what did you say about being under stress?" I wanted that to hit deep, and it looked like it did.

"I'm sorry Percy, I didn't know—" "Know what? That you aren't the only person in the world? That entire time I was wondering how you were holding up. Goodbye Annabeth. Don't ever talk to me again." I said as I left. Now that that was all vented, I didn't want to ruin my friends' days, so I put on a fake smile.

I walked, and saw Thalia whispering to a certain Grover and Nico. They all looked grave.

"What is it guys?" Hoping that they didn't hear about Annabeth and my fight.

"Percy, there's this new camper, and he was just claimed. "Pause for dramatic effect, of course, and finally "he's the son of Poseidon."

There was a fleeting emotion of jealousy, but then was overjoyed. Awesome! I'm going to have a non-Cyclops brother! When they saw my face (which was smiling) their looks got even greater.

"Percy, you remember the kid who kept on talking about himself as if he were the most important person in the world?" Nico asked. Uh oh. I sincerely hoped it wasn't that guy. It was some all-American guy. He was really annoying. Oh well, I suppose I didn't really have a choice. With his ego, it wasn't like he would get any friends.

Next week.

I saw a letter on the floor, which said Son of Poseidon. Figuring that it was either for me or my brother Alex. I opened it, and saw that it was from dad. I started reading.

Dear son,

I hope you are liking camp so far (okay, I've been here for a while, but whatever) and I would like you to come down to my palace for a week so that we can train together! (cool!) Just make sure that when you are at the gate to say that you are Alex, son of Poseidon, and that you are here at my request.

Love,

Poseidon.

Oh. It was for him. Never mind. You know in the past week or so, I had noticed that Poseidon was paying a lot more attention to his mortal son rather than me. Alex was getting along with everyone at camp, and ever since the Minotaur somehow got in and he killed it, everyone has been praising him and ignoring me. Now, I am not looking for compliments all of the time, but I would still like to hang out with my friends and stuff, rather than have them not say a thing when Alex says to screw off.

The next thing I felt was a humongous wave of hatred, resentment, hurt, guilt, and just loneliness, like I was a used newspaper. So, I ran away. As far as I could, telling Grover (the only person that had hung around me and actually enjoyed it, along with Nico, but he was in the underworld right now, so I couldn't really go and hang out with him.)

"Percy, before you go, stay for another hour or so, because I want to have a goodbye feast, and umm, I made you a shield." What? One, I already had a shield, and two, Grover didn't seem like the type to make shields.

"Yea, I know that I'm not the best shield maker in town, but I hope you keep it in memory of me. It took me a couple years (since you took up the sky), but it's almost done now. I'm just letting it harden." He walked me over to it, and I saw a black Pegasus with me riding it, and pictures with Grover and me on it. It looked at it, picked it up, and marveled at it. I was light, it could transform into a watch that told the time no matter which time zone I was in, and would return to me if it got lost. He said the delay was a couple seconds longer than Riptide, but that was still good. It was made out of some of the hardest material in the world, and had a button that would make a sharp blade come out of it's perimeter, and it could shoot a poisonous or sleeping dart out. Grover said that it had unlimited supply (thank magic) but it took about a minute to recharge after each use. There seemed to be a little pouch of water hanging on the inside.

"That's healing water. It can be used for anyone, demigod or now, but the isn't very much. Cuts or bruises wont take any away, but if you're sick, this will cure you. Percy, the only reason I have any of this is because I'm the God of the Wild."

Think of every good emotion in the world, and how they make you feel. Now multiply that by about ten, and you had a fraction of how I felt. "Thanks G-man." I smiled at him with brotherly love, and hugged him.

With that, and a goodbye to Juniper, I left. Exactly seven days later, I met Chaos.
