Now, for the chapter...
-------------------

I gulped in the void as Chaos projected an image of himself in his office.

"Perseus. Where to start? There is something I must tell you." Chaos said, his head in his hands.
"What?" I asked nervously, Chaos never was nervous when talking to me.
"I'm afraid I haven't been completely truthful with you Perseus."
"What do you mean?!" I shouted, wondering what he had lying to me about.
"You aren't actually a son of Poseidon." Chaos began.
"Okay....he did disown me. You're  my father now." I said confused.
"No, I mean Poseidon just posed as your father." Chaos said nervously.
"Then who is my real dad?" I asked, completely confused.
"Erm, you don't have one." Chaos said, beginning to squirm around.
"Then who created me?" I asked, an answer suddenly dawning on me.
"I have to explain who and how first. You know about myself and Void, but not about our younger sister, Order. She is your creator, your mother. She created the prison you are stuck in, and as her child, you should be able to get free. There was a prophecy long, long ago...." Chaos explained.
"Whoa. Wait what? Who is Order? What does this mean? So you are my uncle?" I asked.
"Yes, I am your uncle, and same with Void. Order, like it said before, is my younger sister. She kept the peace between myself and Void, and was the perfect soul and warrior, much like you. She's only had one child, you. However, not in the normal way. She literally molded you, putting some of herself in you. You look just like her, erm, without the spell I cast on you to make you look like a son of Poseidon.
But, that was the time that Void was beginning to stir. Fearing your safety, I urged Order to send you to earth undercover. We bent the minds of Sally Jackson and Poseidon to make them think you were Perseus Jackson. Son of Poseidon. We blocked all of your powers except your Poseidon ones, and when you came to me, I unlocked them. So, you have no father, but Order is your mother.
This means that, like I said earlier, you can break out of the void. I don't know how, but, as a child of Order, and your fatal flaw being loyalty, you will find a way to come back to Earth and your friends.
Um, and when you get back, I'll have to remove the spell on you, that changed your appearance. I won't tell you what you look like, uh, I'll keep it a surprise." Chaos said, calming down now a little.

"Oh," was my intelligent response. "Got it. Wait, please tell me my appearance doesn't look like a male Aphrodite!" I begged suddenly, horror etched across my face.

"You'll just have to wait and see." Chaos smirked.

"Gosh darn it holy fish-sticks." I yelled.

"Holy fish sticks?" Chaos choked.

"Oh shut up!" I shouted. "Leave!"

"Yes Sir! And one more thing, you can't tell anyone about your true identity, and you'll have to change your appearance back to Perseus."

"You keep talking as if Perseus isn't my name. If it's not, what is?!" I shouted, just as the screen began to flicker. It was hard to see, in the blackness of the void.

"Nova." Chaos shouted as the screen flickered and popped one last time, before completely disappearing.

Nova. I thought. Wait, isn't that Jason's (the original) code name? My ADHD brain asked. I ignored it. Now to get out.

I had gone back to being blind for the moment, but I didn't need to see. Focusing my energy, I searched for the heart of the wretched prison. Sensing it, I channeled all of my stored up energy and blasted myself there. Once again searching, I found the exact center of the prison, floated on it and created thick walls around it. I stood now in my own little circle. No one could get in.  Using the last of my energy, I gave it all I had. Hopefully a huge stretching line of pure power went in all directions, shattering the walls, and yet somehow teleporting me out.

I found myself blind in an unfamiliar place, before something was waved under my nose and I passed out.

I awoke, still blind, lying on something soft. "Hush my dear one. Your vision shall return soon. I saw your beacon of light coming from the void, and rescued you. Welcome to my home of peace."

"Order?" I croaked.

"Yes my child. Call me what you want, I know you were about to ask. Nova, I have missed you."

"Nova, heh. That's my new name now. I keep on changing my name. Cool." I said, smiling at my mother.

"Very cool my dear. Now, you must get back to your friends! The war is not yet over, and your interference has stirred Gaea. Run now, my child. I will teleport you to Half-Blood Hill, and you will know what to do from there. Good luck Nova, or Perseus."

"Thank you mother." I said, and wrapped her in a large bear hug. She accepted it immediately, radiating power, an aura of safety, and smelling like mint and the fresh wind.

"Now go, my son. Destroy the evil, and restore peace to Earth." My mother commanded, and teleported me back home. Or well, my old home.

Camp Half-Blood.
