Chapter 1

When I come to I'm lying in a cot inside what looks to be an infirmary tent. My brother is lying in another cot next to me still asleep, his forehead bandaged. I rush to his side but before I can start my usual first aid checks a golden haired eleven year old boy in an orange shirt boasting 'Camp Half-Blood' and a first aid cross on the front of it and a tan pair of cargo shorts intercepts me.

"WHoa, hey he's fine. He's fine. You shouldn't be moving just yet, Jackson. You took a rather big hit before reaching Half-Blood Hill." The boy radiates concern and sincerity, but that's my big brother lying limply on an infirmary cot in what looks like the middle of the forest. My big brother, who always seemed so strong and invincible when he defended me from monsters, was lying in the middle of a forest with a head injury instead of an actual hospital.

I frowned up at the boy who was pushing me back down onto my own cot, "Why isn't he in a hospital if he has a head injury?"

"Because he's safer here than he would be in a hospital. He'll be fine. We're feeding him nectar to help with the healing." The boy is distracted as he answers, examining my own injuries.

He frowns at me in incredulous, confusion, "You took a rather hard hit to the head from what Grover tells us is a car crash, you had many scrapes and at least two gashes from the broken glass so you lost quite a bit of blood. It's only been thirteen hours since then but your scrapes are gone and your gashes have practically sealed themselves up?"

I didn't see the point in not answering his unasked question, "It was raining last night right? My brother and I have some type of hyper regeneration while we're in water."

The boy's face brightens and I can see the awe in his blue eyes, "Well that's quite handy. So should we submerge your brother in water to try and speed up his recovery?"

I nodded, glad the boy seemed to understand my point so easily, "Yeah we can breathe underwater as well so it can be a full submerge. It shouldn't take more than a few hours to get him back to normal and he'll probably wake up before he's finished completely healing. Watersortashocks our system into hyper awareness and once he's aware enough he'll start consciously directing the water to heal himself faster."

"Huh," the boy seemed more than a little stunned, "it sounds like you and your brother have more of a handle on your powers than most of the kids here. Your brother is twelve right?"

I nod, more than a little proud of my brother and it must show because the boy is looking at me in amusement, "Yeah, once we realized what we could do, my brother and I started training our abilities as much as possible. My brother heals faster than I do and can sometimes force our water regeneration to heal other people but I'm the opposite. I can force my water regeneration to heal others more easily than I can myself and I heal most in the water and unconscious, but like I said waterkindashocks our system and wakes us up so it takes me longer to heal in water than my brother."

The boy nodded his understanding, "It sounds like your more of a healer than a fighter like your brother is. I'm going to get a couple of my brothers to help carry him down to the lake then."

He turns to leave, before turning back and saying, "By the way, I'm Will Solace, son of Apollo."

And then he leaves me there stunned.

Not much longer later he comes back with two other boys who look almost like an older version of him and what looks to be a centaur.

"Ah, Ms. Jackson. I'm glad to see you awake and well enough. We were quite worried at your... rather difficult arrival." The centaur says as Will and his older brothers heft my brother into a stretcher to take him to the lake, "Come along, we must get you settled."

I nod a little dazed, but Will speaks up from the entrance, "Don't let Jackson stay up for more than a couple hours and I haven't fully released her from the infirmary yet."

The centaur nods and begins heading back out of the infirmary, still speaking, "My name is Chiron. I'm the camp activities director."

I follow Chiron slowly, "Where are we going?"

"To meet the camp director, Mr. D." Is all Chiron says.

I frown as I suddenly remember, "Where's mom?"

Chiron pauses before turning towards me and telling me, "I apologize but your mother is gone, Ms. Jackson."

I stop, frowning, "That's rather strange of her, I would've been sure that she would've said good-bye to us first before leaving, especially as we were both injured in the car crash."

Chiron grimaced, sympathetically, "No, Ms. Jackson, I mean that your mother was killed before you could reach camp."

"W-what?" My voice trembled and my eye's burned, "T-the car crash?"

He shook his head, "No, my dear. Pasiphae's son."

Pasiphae's son. Pasi-...the wife of Minos, mother of the Minotaur. But -...

"But he was killed by Theseus?! How could he-" I began to rage.

"My dear, the monsters of myth do not have souls and thus with enough time can be reborn. I am truly sorry for your loss, child." Chiron was trying to be delicate but I didn't want to hear anymore from him.

I ran back in the direction my brother was taken, tears streaming down my face and ignoring the shouts to come back. Dark clouds were gathering above us and the wind was picking up. I ran for the pier, where Will and his brothers were lowering my brother into the lake, one of them already in the lake.

Will heard me coming, and looked concerned. He opened his mouth to say something, but I ignored him and threw myself past him and into the lake.

My emotions were in turmoil - rage and sorrow and disbelief warring to take precedence. The shock of the water, usually such a healing balm for my soul and body, only made me hyper aware of my loss. I screamed my rage and sorrow to the dark depths and the water began raging and churning around me. I don't know how long I was down there at the bottom of the lake screaming and sobbing into the sand, but it was long enough that my brother woke up and pulled me into his arms.

When I finally regained my senses, we were surrounded by marine life, naiads and there was a literal mermaid waiting with downcast eye's. She seemed to sense my gaze because she lifted her head to look at us and gave us a small sad smile.

"Feeling any better, Cas?" My brother croaked at me, his arms tightened around my shoulders and waist.

I snorted, wetly, "Not really."

He nodded seriously and grimaced, "Yeah me neither. I suppose a better question would be: do you have control over yourself now?"

I considered the question. My emotions seemed settled for the moment, or at least I was tired enough that they seemed duller. We were in water right now though, literally at the bottom of a lake that opened out into the sea. I'd never felt tired before when I was in water and it worried me a little. How long had we been down here? How long had I raged? Had I hurt someone when I lost myself?

My brother of course knew immediately were my thoughts were heading, "It's okay. You didn't hurt anyone."

I relaxed and slumped into his lap, exhausted, "Do we have to go back?"

He sighed, "Not immediately. We've been down here for three days now though. Another night won't really matter."

Three days huh... that should worry me or at the very least confuse or interest me, but I was too tired and far too uninterested in anything really. I fell asleep as my brother made himself comfortable and curled himself over me.

The next morning I woke to my brother talking to the mermaid, "...Cas'training. They were just upset. There's not really anyway anybody can prepare themselves for something like that to happen, especially at their age. Hell, even at my age! You just can't prepare yourself to lose someone. And there's no easy way to tell someone that type of news. Nobody was hurt though and the other campers only had to deal with a few days of cloudy weather and a few missed canoe lessons."

"Your father has bid me to tell you that he'll have no choice but to claim you. Lord Poseidon warns that it is too dangerous to claim Castor just yet, but you, he will at the very least have to claim. He bids you to keep Castor close while they grieve and while you are at camp, but when you need to leave camp, he instructs you to leave Castor in Lord Dionysus' personal care. " The mermaids voice is soothing and musical.

"Alright, I'll keep that in mind."

"Good day, my lord."

I sigh and begin sitting up, "I suppose we must go back now."

Percy nods, "Will and Chiron were quite worried when I first woke up. Come on, I'll give you a piggyback ride."

I floated over to him and curled into his back, letting my head rest on his shoulder. I was awake now, but I didn't want to be. In fact there wasn't much I really wanted to do at all, except for maybe hold on to my brother like a limpet.

Percy propelled us both up to the surface and swam us both easily to the shore. It was only once on the beach that he really stumbled and both of our stomachs growled.

"Jackson!" Came a relieved shout from the direction of the infirmary.

"Chiron! They're back!" Came another shout.

I didn't bother to look up from Percy's shoulder, even though we were quickly surrounded by campers rushing to either see us or help my brother.

My brother carried me past all the curious campers and straight to the big house by the hill.

"Finally, are you both alright?!" I heard Chiron ask.

"We're not injured. Not sure if we can be in water." My brother mused.

"Ms. Jackson?" Chiron questioned, clearly he wanted an answer from both of us to be sure.

"Yeah. I'm not injured." I croaked, since I did run off on him. It wasn't his fault mom was gone. He was just the messenger.

Chironhmmedto himself, before thankfully moving on, "I suppose we should get you two settled then."

My brother and I settled easily enough in the Hermes cabin, though it was obvious that we did not leave the other campers with a very good first impression and thus the other campers were wary about interacting with us, me moreso than my brother.

Our father hadn't yet claimed my brother as he had said he would but I knew it was coming. The other campers, especially the Athena cabin and the Ares cabin were constantly sending us suspicious looks, though admittedly for different reasons.

Clarisse La Rue, a daughter of Ares, was the same age as us but a great deal taller, heavier and physically stronger. She was also very boastful, had the attitude of a bully, and devoted herself to her training in order to prove herself the strongest. My brother and I's arrival at camp and our display of power had obviously drawn her ire. She tried to dunk my head in a toilet the very first time I met her in some barbaric attempt at 'initiation' and my brother went off on her, using his hydro-kinesis to blast her into a nearby tree. The Ares cabin has held a grudge against us since. Even if it wasn't our fault.

The Athena cabin was rather odd though. Their ire started with a twelve year old girl with blonde princess curls and steel gray eyes. Her name was Annabeth Chase and she has hated us ever since my brother carried me out of the lake. We hadn't ever really interacted with her at all but she hated us simply because she suspected we were the children of the sea god, Poseidon. Poseidon who was her mother, Athena's, hated rival. That was all. Nothing we specifically did, but because her mother hated our possible father. Personally, I think she is right about our father but to hate us simply because of our father and her mother were at odds was a little extreme and highly illogical.

Despite everything that had happened and everything that had changed, I found myself actually enjoying being here. I was still grieving but the constant training and learning of new things kept me busy and distracted. My brother seemed to thrive here as well.

That first week Chiron had instructed us to attendsoooomany different lessons in an attempt to both help draw out our powers in order to figure out our godly parent and to figure out where our strength lay.

My brother and I are near complete opposites, is what Chiron finally decided, as if we had not realized that long ago.

I was decent in archery but my brother was forbidden to touch another bow at camp after Chiron had to de-snag an arrow from his tail. He was behind my brother when he made his shot. I've never laughed so hard, but my brother just blushed and grinned widely at me. It had been the first time I'd laughed since mom's death.

Neither of us were very good at wrestling, though Percy managed at least somewhat of a fight. I, however, didn't have the strength or weight to pin my opponent, but neither could anyone manage to get a decent grip on me either. Every single opponent I faced left that mat bleeding and bruised from my scratching, biting, headbutting, kneeing, elbowing, and pinching. I quickly earned the nickname 'Wild Cas', or 'Savage' among most Athena and Ares kids. When other campers tried to tell my brother or Chiron that I was doing it wrong or that I was cheating, my brother would roll his eyes and tell them that it worked didn't it and Chiron would simply say that anything goes in a life or death situation and that I was using my size, dexterity, and dirty fighting to my advantage. A lot of the other campers started glaring at me when some of the younger kids started following my example. I just grinned and giggled when another kid my age was pinned but their opponent had to head for the infirmary. Percy just snickered into my ear as he held me from behind. After losing our mother we were both probably far more clingy than other siblings and we often got odd looks for it but neither of us gave a damn.

When it came to foot racing, I was far faster than my brother, but nowhere near as fast as our Nymph instructor, who told anyone who questioned it that they were used to running from gods. That confused me, but my brother had a rather irritated and exasperated look on his face that made me think I didn't want to know.

We both excelled at canoeing and swimming of course.

My brother somehow managed to disarm Luke Castellan, son of Hermes, during swordmanship classes and the entire camp was talking about it for days, apparently Luke was the best swordsman that camp had seen for nearly three hundred years. I, however, couldn't really manage sword fighting but Chiron urged me to find a bladed weapon that I could manage. I ended up being pretty decent at dual wielding daggers and staff fighting. Chiron liked our ideas of collapsable staffs and set the Hephaustus kids to something similiar but more durable for our spears.

Both my brother and I were pretty agile, dexterious, and strong enough for the rock climbing with the falling lava rocks to be no real issue for us.

The Apollo kids commandeered me for demigod healing once Will told them I could heal others with water and I demonstrated that it wasn't a lie. So now whenever I'm not in lessons forgreek,latin, mythology, dagger training, archery, and obstacle course and parkour training, I'm in the healing tent with the Apollo kids helping deal with injuries. They were training my brother in demigod healing as well but when it came to more serious injuries they would be dealt with by either the Apollo kids or me. Healing came easy for me but it was also very tiring. After falling asleep in the infirmary a few times after a long day, my brother put his foot down and restricted me to no more than two hours of healing until I got older. Percy laid into the Apollo kids for overworking an eight year old, while I pouted. I liked healing work.

In the little free time I had I watched the Hephaestus kids in their forges and the Aphrodite kids weaved bracelets. I found the whole process of creating things fascinating. I think when I got the chance I wanted to try learning that as well. At the moment I had far too much on my plate.

It was after winning Capture the Flag that my brother was claimed by Poseidon, proving Annabeth had been right about our father. Everyone had been looking at me expectantly after that but I just glared at them. I understood my father's reasoning. Claiming me would put a target on my back just like Percy, but at least Percy was a fighter and a strong one at that. Me, I was a healer first and a mid to long ranged fighter, a supporting fighter at best. I was decent at hydro-kinesis, but nowhere near as powerful as Percy. I was also eight years old and shaped like a possible hostage for anyone wanting to use me against Percy and our father. So long as he didn't claim me just yet I was somewhat safe and my parentage was merely cast into doubt. The moment father claimed me I would be at risk.

Annabeth and Clarisse fell even lower in my eyes that night. Annabeth because she was on our team but had deliberately set my brother up as bait for the entire Ares cabin and Clarisse to jump him in an effort to distract them from their flag. And Clarisse of course because she was a participant to beating my brother, though luckily they were near a creek so my brother healed quick and easily enough and even managed to turn it back around on them. I didn't care though, I was outraged at Annabeth, Clarisse and the Ares cabin for their actions against my brother, especially Annabeth who had apparently just stood there and watched invisibly as over a dozen Ares kids jumped my brother.

From then on I refused to heal anybody from Ares or Athena's cabin. Chiron tried to talk to me about forgiveness and the burdens of holding a grudge, but I was an eight year old who volunteered to help heal, nobody could force me to heal someone I didn't like. Especially people who had made the choice to harm me and mine for their own grudge or our parents grudges. Chiron conceded my point and urged the Apollo kids to keep me away from any Ares or Athena kids until I had settled my issues with them or could get past my anger and hurt.

Some of the older Apollo kids didn't like that I could pick and choose who I could heal. It was after nearly ingrained in some of them to heal any and every injured person they came across, but they seemed to come around to my point of view and I'm sure it had to be because of Will, who I had become closer with since coming here since I was more often than not in the infirmary tent healing in my free time with Will there to help guide me for any new injuries.

Read and Review Please. Let me know if I should continue this. Also if you have issues with the way I portray Annabeth or Clarisse - keep in mind that both Percy and Castor have already showed a deep connection to water so Annabeth is already considering them an enemy of her mother's and the capture the flag thing was literally what she did and it was one of the main reasons I couldn't stand her for a long time. Clarisse is just a sheltered bully at this point. Both girls will growup.
