A/N: I've decided to start this! I'm still confused on whether I should do first person for Percy so tell me what you think!

It was a month after the Titan War when my dad came up to me. "Hello son." Poseidon said. "I have important news to tell you."

Now, when a god tells you that, it's never a good thing, so there I was worried to death that it was something so horrific. Like Tyson died in the Forge. If that had happened, I don't know what I would do. "Ok, what is it?" I asked hesitantly.

Poseidon sighed and looked down. He was wearing his Hawaiian shirt with some khaki shorts. "You have a sister."

I blinked about a million times. "Did I just hear you correctly? I have a sister?" He nodded. "And you didn't tell me any of this! Are you kidding me?" I blew up.

"There's another thing…she's your twin sister." Poseidon said.

"You're lying. No-no, you're pulling my leg! That's what you're doing. I think I would know if I had a twin sister." I told him.

"Not unless your mother and I decided to put her in foster care. Somewhere far away. Where you wouldn't feel the pull of your sister." Poseidon said.

"What are you talking about? 'Pull of your sister'? That makes no sense." I exclaimed.

"I mean, when you two are together, you two will know that you two are brother and sister subconsciously."

"Ok…suppose I do believe you…what do you want me to do about it?"

"Find her. It won't be a quest. I promise you that. You don't need to go see the oracle or anything. All the gods have decided on that. I haven't claimed her so she won't know who or what she really is. I didn't want her to freak out and to make her come to the camp when you are already here to fulfill the prophecy…I didn't want her to have that same burden you do. And anyways there's another prophecy about twins born to one of the three big gods. A prophecy when the time comes you will hear it."

"What? Another prophecy? Don't we already have another big prophecy on our hands?" I asked.

"Yes but…this prophecy had come right after the first big prophecy. And to let the other gods know I had most likely singlehandedly made the two that could fulfill that prophecy…I couldn't let them know that. But now…I want her to be found. You will find her in Texas, where the grass was once filled with Buffalo. Where there are cotton gins and a Parade for Christmas and a parade for Homecoming. It is almost time for homecoming. She will be with the marching band. Her name is Aeryn. Don't ask why. That is not what we decided, your mother and I, we had decided to name her Nixie. Though they decided to have that as the middle name." Poseidon said.

"Nixie…ok, I'll remember that." I told him.

"Oh and you can bring along two other people." Poseidon said. "I have to go, but remember, leave before light tomorrow. Chiron knows of what you have to do so do not worry."

I nodded and said, "OK." When Poseidon left, I ran towards Annabeth and Grover. "I have some BIG news to tell you."

"What? What is it?" Annabeth asked looking at me in concern.

"I have a sister. No not even that, a twin sister. And I have to go find her in Texas. Something about 'where the grass was once filled with Buffalo. Where there are old cotton gins and a parade for Christmas and a parade for homecoming'. He also told me she is in the marching and, her name is Aeryn Nixie…her name was supposed to be Nixie but her parents changed it to Aeryn for some odd reason."

"Are you high on nectar?" Grover asked. "I mean, come on. Why would we just hear about this now?"

Annabeth frowned and then grinned. "Let's hope that she's not a seaweed brain like you." She joked. "I can gather some of my stuff and then I'll be ready."

"Meet me at my cabin, I need to get some stuff too." I told her. Grover followed me as I went to my cabin.

"I can't believe your dad just dropped that on you! Why didn't you know before hand?"

"About some other prophecy, about twins. I guess twins of the big gods are powerful."

"I don't know. I don't think it's ever happened before." Grover told me.

"Then this is the first and I will find her." I told him.

"Ok. We will help you." Grover said.

I grinned. "I wouldn't want anyone else to accompany me." Grover grinned back at me. I went in and grabbed a back and put a pair of clothes in it and put my watch on that Tyson gave me. "Let's go." I said with a sigh. There was a knock on my door and I saw Annabeth. "Ready?" I asked. She smiled and nodded.

"Yes, I'm ready to find your sister." Annabeth said with a grin.

"Let's go." I said with a grin.

A/N: I need someone to do the prophecy, I am so not good at rhyming or anything, so help would be appreciated! And R&R, I will post the next chapter when I get at least four reviews.
