I don't own Percy Jackson series and I think disclaimers are stupid :P

Rating: T for safety and a bit of violence

Pairings: Percabeth, Thalia/ Alpha, Sally J/ Poseidon, Charles/ Silena

Summary: Percy thought he got betrayed by everyone so he left Earth and joined Chaos' Army. He became Aster, the assassin of Chaos, and no one except for Alpha and Lord Chaos knew his identity. 700 years later, the Army is sent to help the gods as Kronos rises again. Would they succeed? Would others know Percy's identity?

Set: well, it's mostly set 700 years after PJ became the Assassin, but there'll be two or three flashback scenes where the time is different.

Other: I AM A REALLY SLOW WRITER! IT MIGHT BE ANOTHER MONTH BEFORE I UPDATE SO PLEASE ENJOY OTHER FANFICS WHILE WAITING! THIS PLOT IS CLICHE BUT IT WILL BECOME DIFFERENT! I read a lot of those Chaos stories and I think mine might at least be a bit different as it goes on. For example, it is a Percabeth story. That can already set it apart from a lot of Chaos stories. Second, Percy might be a good, awesome, amazing, best of both the Army and Camp Half-Blood fighter, but he is not perfect. Just as a reminder.

Also, it is not complete sad, depressing or angst and violent or romance story. It does have humor. At least, attempted ones. Another reason the updates will come slowly (really slowly) is that after I finish one chapter, I write it into the characters in there read the story which would end up with a couple of paragraphs changed. Now, if you do read author's note, I'm glad you do, or else you might miss some information.

Chapter one: Mission Two-Hundred-Thousand-and-Something

I quickly scaled the tall walls surrounding the mansion. Landing quietly on the other side, I tiptoed rapidly to the door. It was locked. Feeling like an idiot, I circled the house for another entrance. My feet barely touched the ground as I took a look around. There! On the 3rd floor to the back of the residence, there was a single open window out of view in a corner. I swiftly climbed up and, hoping the floor won't creak, hauled myself through the narrow frame before surveying my surroundings.

The room was dark and mostly empty, with only a couple of boxes sitting on one side. I could see bars blocking my way to the metal door.

Wait! Bars?!

That was when, conveniently, the alarm went off. I swivelled around to jump out the window and found myself facing bars...again. I growled in frustration. The alarm must've woken him already. Why did I have to kill this mortal? Right. The man owed Chaos a lot of money (which he still hasn't returned despite the fact that he lived in a mansion for gods' sake!) and he stole Riptide in my sleep (yes, Riptide as in my awesome sword) though why would he steal some ordinary-looking ballpoint pen was beyond me. Anyways, he would pay on both accounts, plus he's a well-known bank robber. He was going to pay! I would make him!

Footsteps were coming this way. I started panicking. In the moment of panic, I had forgotten to think of a plan. I couldn't get through the bars and unfortunately, I didn't have the power to just turn into a puddle of water and escape. I pulled out my dagger just as the man came in.

"Who are you?" he asked, his voice quavering when he saw my dagger. "What are you doing here? Who are you looking for?"

I froze, knowing he saw me. Then, remembering my 700 years of training, I went to full defensive stance. At last, his eyes narrowed.

"Well?"

"I'm looking for you, of course. The one who stole my s-pen," I felt ridiculous just saying that, "and the one who still owes my er...lord?" That did not sound weird at all... "Ah well, long story short, you are going to pay and you'll never get away with this."

I slowly approached him, but was stopped short by the bars. The man backed up against the door, but seemed to have just realized that I couldn't pass the defence he'd put up and relaxed. It was a good time to strike, but how could I get him? I stared for a while. I found that he bore a distinct resemblance to the unmoving dummies I used for target practice a few centuries ago, when I was a new recruit. Still, relaxed, bald, fat, and most importantly, dumb. I suddenly had an idea. In a flash, the dummy-sorry, man--was pinned to the wall by three throwing knives. He turned deathly pale. Silently appraising myself for thinking up suck a brilliant idea, I said mockingly,

"Sooo...Any last words?"

His answer was composed of a lot of words I shouldn't and wouldn't repeat. At last, he stopped and demanded.

"Who are you? Show me your face!"

I smiled. That was what they almost always asked me in the end. You see, in public, I usually wear either a cloak or a hoodie with a hood that shadows my upper face till the nose so that no one could see it and know my true identity. Only I could take off the hood/ cloak/ hoodie since I never gave anyone else the permission (and anyone who tried never lived long enough to see it properly...except for Alpha, but that's another story). After a moment of silence, I shrugged.

"Sure, if that's your last wish."

I flipped off my hood to show my unkempt black hair and a pair of sea green eyes that practically shone in the dark.

"I am Aster, Assassin of Chaos."

I threw my dagger and it cleanly stabbed him through the heart. His eyes rolled back as he slumped down, dead as a doornail. I found a long hook in one of the boxes stacked by the side and managed to retrieve the key to unlock the bars. That done, I was free again and it only took me about 15 minutes to find Riptide which was in one of the drawers of his office. I also found the place where he kept all his money (the guy didn't have a bank account, probably afraid that some other criminal would rob it). I pulled out a bag and stashed in it the amount of money the man owed Chaos.

I leaped out the window, landed safely on the lawn, scaled back over the tall wall, and disappeared into the shadows, satisfied of finishing my mission after two days.
