This is my first Fanfic, any review is nice.

Quick Summary: The seven, plus Nico and Thalia, go to Hogwarts to protect the golden trio, but they go truly as half-breeds. There will be Percabeth, I am not sure if I add other pairings in, there will be absolutely Thalico, I do not approve of this pairing, simply Thalia is Lieutenant of the Hunt, and Nico does not swing that way.

I do not own PJ/HOO or HP, no matter how many coins I throw in a wishing well.

Chapter 1: The unexpected Changes

Percy POV:

I woke to the sound of screaming, it took a couple seconds for my brain to register who was screaming, as soon as I recognized who it was I swore and sprinted out of my cabin straight to the Athena's cabin. With only one thought on my mind

"Annabeth"

As I reached the door of the cabin I heard another ear splitting scream, I banged on the door to let me in to see her. Malcom opened the door and started to say they can handle it, but without a second thought I pushed him out of the way and ran straight towards Annabeth's bed. She was wrestling with the sheets pure fear and panic was strewn across her face. I pulled her close to my chest and whispered into her ear

"It's ok, we're out, and we're together. I'll never leave you, I'll never let you go, and you know this. Please Annabeth wake up, please let me look in to the eyes I love so much. Please. Please Annabeth wake up."

As those words leave my lips I feel tears well up in my eyes, and feel them roll down my face.

Suddenly Annabeth's eyes snap open, fear, panic completely over taking over her eyes. The normal analyzing gray eyes, that I loved to stare endlessly into, were now a dull, worn, ghostly pale gray. I pulled her close to me and continued to whisper in her ear.

"Annabeth, I love you, I will never leave you, I will never betray you, I love you."

Whimpering Annabeth replied "I love you Seaweed Brain."

Slowly her breathing calmed and she drifted back to sleep. As soon as I knew she was a sleep I let out a breath that I didn't know I was holding. I looked around the Athena cabin, the Athena campers had a mixture of fear and confusion in their eyes, the only ones besides the seven that knows what happened to Annabeth and me are Chiron, Nico, Thalia, Reyna (sorry if spelled her name wrong), our parents, (both mortal and not), and the head of each cabin. I realized that Malcom was gone.

I turned back to Annabeth to make sure she was ok. Her eyes were closed, her face held a calm complexion. I slowly and carefully laid her back down on her bed. Technically I wasn't even supposed to be in the Athena cabin but I didn't care I wanted to make sure that she was ok. I got up to leave, I was half way out the door when I felt a hand lightly grip my shoulder. I look up to behind me to see Chiron, standing in full centaur glory Malcom right next to him. Instantly I knew as soon as I pushed him out the way he went and got Chiron.

Chiron seemed to have a pained look in his eyes, I knew that he was thinking about these last couple days every night either Annabeth or I wake up the entire camp with our nightmares. Annabeth from her screams of pure terror. Mine usually woke up camp, with the reaction to my godly powers, one day I was told I woke up the entire camp by causing the entire camp to flood. If it wasn't for Mr. D and the Demeter kids we would have lost all the strawberries.

Chiron quickly spoke, "After what has happened these past couple days, and that fact that the entire camp needs sleep; I have discussed it with your parents they will allow Annabeth to stay in your cabin."

Instantly I started to walk back in to her cabin to get her and bring her back in to my cabin, but Chiron gripped my shoulder tighter and released a sigh and continued

"Under certain conditions; one, no funny business, I trust you two but it still had to be said. Two you have to keep the cabin door unlocked at all times. If you guys don't follow these conditions Annabeth will be put back in her cabin, and you guys will not be allowed to sit at meals together."

I should probably explain siting at each-others tables, the first couple of days after we defeated Gaia, Annabeth and I wouldn't eat anything. At first no one noticed, but when we collapsed from exhaustion, and mal-nutrition it didn't take Athena to figure out that we weren't eating. After Piper forced us to go on a picnic she stumbled upon the fact that as long as we were sitting together we would eat a little.

After Chiron gave his warning I turned around to get Annabeth, I proceed to her bed I could her breath slowly getting short as if another nightmare was coming, Malcom gave me an overnight bag, probably some clothes for Annabeth. I slowly bend down and scoop her out of her bed, her breathing seemed to calm at my touch. I carried her all the way to my cabin and laid her down in my bed, I slowly slid in next to her and wrapped my arms around her doing my best not to wake her up. As my arms wrapped around her she slowly nuzzled into my chest, I just sat and listened to her breathing slowly lull me to sleep. As I felt myself slowly slip into Hypnos' domain I felt a weird tingling sensation run across my skin, I just choked it up to the fact that Annabeth was actually sleeping in my bed, with me.


Most evil line break

Later that night

Annabeth POV

I know I had another nightmare earlier tonight, I just couldn't understand why our parents were so against us staying in bed together that was the only thing that seemed to slow down the rate in which we had nightmares. Back on the Argo II when Percy and I stayed in his quarter's, there were usually one nightmare each a night, neither really causing any problem. But once we got back to camp and were forced to sleep apart every night as soon as we fell asleep we would have nightmares, which progressively got worse, my screams would wake up the entire camp. Percy seemed to slowly lose control of his powers when he slept, he actually flooded camp, and almost caused a category 5 hurricane that would have completely destroyed all of camp and most of the city. If I didn't wake him up it would have been catastrophic.

When I awoke in the middle of the night I was shocked to find myself in the Poseidon cabin, in Percy's bed no less, and wrapped in his arms. I sighed softly as I slowly shifted in his arms trying to not wake him up, to us two a nightmare-less sleep was an extremely rare occurrence since… that place.

As I slowly took in a deep breath to savor his natural ocean breeze sent, I closed my eyes and just enjoyed being in his embrace, I slowly felt my self being pulled back into Hypnos' realm, but as that was happening I felt a weird tingling sensation run across my ears. I just thought my mom was talking to Poseidon about how she disapproves about me being in his cabin and demands that I go back to hers.

Next Morning

Percy POV

I awoke to a painful sensation running across my body, nowhere as bad as bathing in the river Styx, but it still hurt. As it subsided I felt in one word different, I slowly untangled myself from Annabeth doing my best not to wake her up. I successfully got out of bed without doing so and quietly made my way to the bathroom. As I looked in the mirror my jaw just dropped, my skin was scaly, the scales anywhere between sea-green and a calm ocean blue. But that wasn't the weirdest thing, I actually had gills, that's right I had gills on both sides of my neck, startled they flew open and I suddenly couldn't breathe. Weird because yesterday I could breathe perfectly fine both in and out of water without them. Gasping for air I closed my eyes and concentrated on trying to close my gills, I felt the gills close and I slowly caught my breathe.

I looked in the mirror and noticed my lips looked black, I opened my mouth to see a row of sharp pointy teeth. Frankly I looked I was a child of a merperson and a mortal. I looked over myself to see if there were any other thing weird things, I noticed that there was webbing in between my fingers and toes, the SQR mark was still burned into my skin well scales, and anywhere I used have a scar the scales where discolored almost red or gray.

I panicked, I threw on a pair of jeans, my camp half-blood shirt, and a hoodie in hopes no one will notice. And sprinted as fast as I could to the big house to see if Chiron has any idea of what is happening.
