A/N: Hey everyone! I know this story is overused, but I think this is a good story. I got some of the things mentioned in this story from another person. Their name is Neon Glow Black and the story is called Swords of Chaos: Discovery. Read it, it's really amazing! And Neon Glow Black, if you are reading this, I give you credit to everything that is in your story that I put in mine.

Chapter 1

Unknown POV

I was in Chaos's headquarters on Mars. We had bases all over the universe, but this was Chaos's headquarters in the Milky Way Galaxy. It's quiet big and always has soldiers running around. At the moment I am in Chaos's room with him, and three Vanguards. Vanguards are Chaos's best men. They have been with Chaos for 5,000 years; meanwhile I have been with him for 10,000 years. The three Vanguards are Percy Jackson (20 years old), Thalia Grace (20 years old), and Nico Di Angelo (20 years old). Percy is wearing sea-green armor, but with five white stars on his left shoulder, signifying he is a Vanguard. Thalia has sky-blue armor and the five white stars. Finally, Nico has black armor and the five white stars as well. I, on the other hand, have silver armor with a yellow star, signifying that I am Chaos's second in command. I am still considered a Vanguard, but a higher-ranking Vanguard.

The four of them are in deep discussion about Camp Half-Blood. Apparently, the Greek Gods want Chaos's help to teach the campers about other monsters and other mythologies. They think a problem may happen in the future and want to be prepared. The thing is, 5,000 years ago after a huge war, Percy, Thalia, and Nico were neglected to be praised on their contribution to the war. They fought many minor gods and goddesses, many minor titans, and a whole lot of monsters. Once the war was over, their siblings got their credit. Their siblings said that they were the ones who fought the gods, titans, and monster and the Olympians believed them. The Olympians said that they were their favorite children and that hurt Percy, Thalia, and Nico.

They ran off and Chaos found them, took them in, and treated them like his own. Now, they are the three highest people on Chaos's team, besides me. Back at camp, some of the campers that helped in the war got immortality. Those campers include Annabeth, Grover, Juniper, Jason, Piper, Leo, Hazel, Frank, Clarisse, Chris, Conner, Travis, Katie, Octavian, Reyna, Mark (Percy's brother), Ashley (Thalia's sister), and David (Nico's brother). Even though Hazel, Frank, Reyna, Jason, and Octavian are Roman; the war was with them too, so they got offered immortality as well. Also, Annabeth cheated on Percy with Mark, that's another reason why Percy left.

I forgot to mention, I have the power to be invisible, so only Chaos knows I'm here. Every one of Chaos's soldiers knows of me, they just never met me, not even Percy, Thalia, and Nico have met me. They have all just heard stories of me. Not knowing my name, they call me Chaos's second in command. And I'm 19 years old.

After a while of Percy, Nico, and Thalia trying to convince Chaos to not let them go to Camp Half-Blood, Chaos finally speaks.

"Now, now, you three. It has been decided you will go to the camp. You three are my best, and you three need to go. The Gods need our help, so we will do so. There are no objections. But, I do have someone to go with you three, if you chose to accept them. This person has been with me far longer than you three, and will help greatly. Do you want them?" He tells them.

The three Vanguards look at each other, mentally asking each other if they want this third person. Nico and Thalia nod and look at Percy. He nods as well.

"We want this other person," Percy tells Chaos, "But who are they?"

"Well, you see, this other member has not agreed yet. So I will have to talk to them. I am sure they will say yes, but they will probably meet you there. This person likes to keep to themselves, they're very secretive." Chaos explains.

"Okay Lord Chaos." The three Vanguards say at the same time.

"You three are dismissed. You will leave tomorrow morning." The three Vanguards leave, "Show yourself." Chaos commands me.

I appear a few feet in front of Chaos and he smiles. "I'm guessing I will be the fourth member of this little task force going to the camp?" I ask even though I already know the answer.

"Yes, do you accept?"

"Yes, but what do I tell them my name is?"

"Anything you like. When they see your uniform they will know you from the stories."

"Alright, Chaos. Good night!" I tell him.

"Good night, my little one!" I smile, he always calls me little one, it's my nickname.

I disappear again walk out of Chaos's room. I have my own private room in this base, just so I can keep my secret. In the hallway to my room I see everyone rushing around. Some of them are even in the café we have on base. We have to drink coffee too! At the café, I see some of them smiling and just plain having fun. We are like a big family here; nothing can get in the way of that.

Once I get to my room I change into my pajamas and lay on my bed. Tomorrow will be a weird day. Oh well, I'll just have to deal with it. In a matter of thirty minutes, I doze off.

Percy's POV

Once Nico, Thalia, and I left Chaos we went to our room. We all share a room because we are all really close. Once we got there we all changed and sat on our beds. How can Chaos expect us to go back to that camp? He promised us and now we have to go back! I know Nico and Thalia hate this too because once Chaos announced we had to go back, they had scowls on their faces.

"Well, this sucks ass!" Nico says and I nod in agreement.

"Right, now we have to go back and see everyone again. The only one that actually cares about us is Chiron. I mean, he's the only one that has been praying to every God out there that we come back. The others don't even deserve us!" Thalia semi-yells.

"Not to mention, our siblings." I say in disgust. Then a thought crosses my mind. "Hey guys, who do you think is our fourth member?" Thalia shrugs.

"I don't know, man. Chaos said they are older than us and will help us greatly. Who is older than us and at our level?" Nico asks.

"No clue, everyone older than us we know. And Chaos said they are secretive, so who is secretive here?" Thalia asks.

"This is useless, we will just have to wait till tomorrow." I tell them and they nod. "Let's just get some sleep, we'll need energy for tomorrow."

I lie down on my bed and try to relax. No use, all my muscles are tense, anticipating tomorrow. I have to see all my friends that abandoned me. I have to see Annabeth again, who broke my heart. Grover, who was my best friend that left me for my brother, Mark. And all my old friends. Gosh, tomorrow will be horrible.

I woke up in the morning and looked at my watch, it read 5:45 a.m. We have to leave at 6:30 a.m. I get up and wake up Nico and Thalia. They just groan in response to try and wake them up. I decide to go take a shower first. I go to the bathroom and take a quick shower. Having the water run down my body makes me feel 100% better. I get out of the shower and change into my uniform. Once I get back to my room I look at the clock and realize it's 6:00 now. I go to Thalia and Nico and throw them both of their beds and they get up. They look at me with the evil eye, but all I do is point to my wrist, signaling time. They look at the clock and their eyes grow wide. The curse as they run to different bathroom to take a shower.

They come back at 6:20, already dressed. We go to the café and we all order hot chocolate. Once we get our drinks we run to the hanger, that's where they keep all the spaceships, planes, and all that other aircraft. Chaos is there waiting for us.

"Here with five minutes to spare, nice job guys." He smiles, "The fourth member agreed, as I said they would, and they said they will meet you at the camp. They might be a little late, but no worries, they will make it."

We nod as we get into the ship. I have no idea how to fly this, luckily Thalia is here. I know, she used to have a fear of heights, but since Chaos, she has gotten over that fear. Now she is the best pilot in all of Chaos's air force. Thalia sits in the pilot's seat and starts pressing random buttons. Well, random to me because I have no idea what they do. It probably makes sense in Thalia's head, though.

Nico takes shotgun and relaxes. I take the seat behind Nico. Nico's seat can turn, so he turns it so he's facing me. The whole ride to Earth, Nico and I play cards. We always play cards when we are riding together. We play Go Fish, Palace/Castle, and Slap Jack. Three hours later, we are finally at Camp Half-Blood.

We each get out of our seats and stand by the doors. I turn to look at Thalia and Nico. "Ready?" I ask.

"Nope." Nico says and Thalia shakes her head.

"Here goes nothing." I press the green button to open the doors and I see all the campers there. I see new faces and old faces. I smile when I see Chiron. He gallops over to us.

"Children, it is wonderful to see you three!" Chiron says. We each hug him. "I'm guessing you three are three of the four coming from Chaos?"

"Yep," I say, "The fourth member is still not here yet. Lord Chaos says they will be here a little late. And no, we don't know who it is."

Chiron sighs. "Very well. We had Leo, you know Leo right?" We all nod. "Yes, well Leo built a Chaos cabin so you can all stay there." This makes all three of us smile. Then, the moment was ruined.

"I guess they're too scared to stay with us, their siblings! They know we can beat them up, so they need their own cabin!" Everyone laughs at this comment. I look to see who said it; I see my half brother, Mark. He is standing next to Annabeth and they are holding hands. This angers me a little.

I feel a hand being placed on my shoulder. It's Nico's. "He's not worth it, Perce."

Everyone's laughter drowns out and they are all pointing to Half Blood Hill. Everyone has questioning look on their faces, including Thalia, Nico, and I. I look out into the hill and I see a figure walking towards us. Then, I see them. They are wearing sliver armor and a yellow star on their left shoulder. I look to my left and see Thalia and Nico on one knee and bowing their heads. I follow their lead. Before I know it, the entire camp is doing the same thing, except for Mark.

The figure approaches us three. "Vanguards stand!" The person tells us. I realize that they are a girl; they have a girl's voice and figure. I also realize that they are Chaos's second in command form the stories. We all stand.

"Who the Hell are you?" Mark yells.

"Child, don't start with me." Chaos's second in command says surprisingly calmly.

"Who are you calling child?" Mark yells even louder. He has to show respect. I guess Thalia reads my mind.

"Watch who you are talking to and show some respect!" Thalia yells at him.

Chaos's second in command holds up a hand to Thalia. "It is alright. This boy simply just needs to learn manners. I'm sure that can be arranged." She says with a smirk.

Apparently Mark doesn't understand he has to back down and charges her. She sighed and raised her two hands. Then, she did something that surprised me; she shot a plasma ball out of her hands. It flew and hit Mark. He went flying twenty feet and just laid there. I thought only I could shoot plasma, I guess not.

Annabeth then ran to her. "You don't have the right to hurt him!" She screamed at her.

"He has to know his manners, he had no idea who he was talking to." She explained calmly.

"Who are you?" Annabeth demanded.

"I am Chaos's second in command. More powerful than you will ever know."

"Well then, that explains nothing!" Annabeth says rudely. "What is your name?" She says very slowly like Chaos's second in command has a mental problem.

"You don't need to know my name. But, you may call me Jackson." Why do we need to call her Jackson? Isn't that a boys name, and it's my last name.

"Stupid name, Jackson!" Annabeth said practically spitting in Jackson's face.

Jackson then walks towards the crowd and they part for her. She then walks to the Chaos cabin. How she knew that was the Chaos cabin, I don't know. I turn to see Thalia and Nico and they are just as confused as I am.

A/N: That's the first chapter, I hope you liked it. This is longer than I usually write, so it's going to take me awhile to update. What did you guys think of this though? And what did you think of Jackson? Would you guys want to see Thalico in here? Just questions to ponder about. Please review! And if I don't update right away, it's because I'm working on my other story called Jake, The Son of Zeus and Jupiter. Please read that one too. Till next time, let the odds be ever in your favor!
