Percy Jackson has a sister.

We fear for the worse

I feel an urge to run, but Percy and Annabeth block the doorway. I look at them, but they just stare at me in shock.

"We should probably tell Chiron" Annabeth murmurs, and that's when Percy comes back to his senses,

"Yeah we should" he said, it sounded like there was a twinge of jealousy in his voice.

As we walk up to the big house we are joined by Ryan and Jason. I try and avoid them, but Ryan just stares at me,

"So your Percy's sister who his dad kinda promised to send?" Jason asks me. I look at him, his electric blue eyes are more startling,

"I was a promise to Percy from Poseidon?" I ask raising a eyebrow, Percy looks at me, he puts his hands up,

"No, dad said he would send me some brothers and sisters, at the end of the titan war." I look at him, the titan war ended ages ago, "And no, there was another one, did you hear about the destruction done at the end of august and few years ago?" He asks, I stare at him blankly, "OK, well we defeated Kronos together," he said looking at him and Annabeth, "And then 7 of us defeated Gaia," a sad look crosses all their faces,

"Unfortunately we lost our friend during that war, but we will not forget him, or anyone else," Jason tells me. They all head into a convocation with each other, so I looked away. I felt a tug on my arm, and I look to where it is,

"We need to talk," Ryan says and then he walks off. As we reach the office, a young person stands there, his clothes in tatters, and he is talking to Chiron,

"Aaron?" Jason asks.

The boy looks up, and he smiles at Jason, he has blue eyes and a devilish grin, he looks like a Hermes boy, but we will have to wait and see. Chiron comes over,

"Chiron we need to talk to you!" Percy says, he looks at us,

"Very well, let's take this inside, I believe its a big matter," Chiron says, he heads over to the big house and we follow him, leaving Jason and the boy Aaron behind, just as I walk past him though, he grabs my arm, and says,

"Do I know you from somewhere?" I look at him, and shake my head.  When we reach the big house Chiron looks at us expectantly,

"Poseidon came to visit me," I start, "and he said that I am more god than human, and that my mother has a secret that only she could tell me, and that my great grandfather doesn't know of me yet, cause she broke the rules," I say. Chiron looks at me, and Annabeth, she nods to confirm it, and then he looks at me again.

Chiron stares at us in shock, he strokes his beard, obviously thinking,

"My dear I think then it is best that we then train you as hard as we can," he says, I nod at him, "And I would also like it Percy if you could help her, teach her how to control her powers," he carries on, "I fear this is going to cause trouble," he then turns and walks out before giving us a quick look, he tries to smile but something clearly isn't right.

"Ok well if Chiron told me to help you use your powers you seemed to have found the perfect place, let's go, oh and Annabeth your late for sword fighting practice," Percy tells her, she smirks at him, and walks off, "Don't I get a kiss,?" He asks, she turns around and roles her eyes, but she comes over and plants one on him, and runs off. Percy watches her in awe, I shake him and we move.

As we head back into the Poseidon cabin, he asks me a question,

"Yesterday when you passed out after a dream on something, what did you see?" I stare at him, I hadn't ever actually told anyone about it, but he is my brother,

"I saw myself falling into an endless pit of darkness." I say, immediately he straightens his back and looks at me, something sparks in his eyes, and he looks like he is about to burst into tears. He turns away and heads down the ladder, when he reaches the bottom I follow him.
