A/N: Nothing belongs to me but my OC Cooper

Percy POV

Pain. That was the only sensation that i could feel. It was in these moments that i could feel why being loyal is actually a fatal flaw. Its not because of what happens in battles or everyday life, but what happens when all you cared about turned away from you and you are left with a broken heart. That is real pain. I suppose you are wondering why I am in such a state? Well, I guess I should go from when it all started, for that week after the Giants war when my life took a turn for the worse...

Time jump: 1 week in the past

I and my brother cooper where (a/n cooper was with Percy on all his quest and instead of a sword as his weapon he uses guns, and is mersulis to his oponits) sitting contently with my friends, all laughing together without a care in the World. My beautiful girlfriend, Annabeth was beside me, my hand on top of hers. We could finally be together, no dangers, no looming wars. We were at peace, having just won the Giants War and with the next great prophecy not being said, implying many years of peace. That's when HE showed up. A loud clattering could be heard at the camp borders, and my friends and I immediately got out our weapons and rushed to the camp borders. The war may have been finished, but that didn't mean that monsters didn't still roam around the world and around Camp Half Blood. Once we arrived at camp we saw a lone boy being chased by none other that The Minotaur. The boy quickly looked up and I could see his sea green eyes that looked so much like my own. Oh the irony, another son of Poseidon being chased by the Minotaur, just like what happened to me and Cooper all of those years ago. After i got over my initial shock that my dad had another son other then my brother,(Percy and Cooper are twins) I wondered if i should see how my apparent half brother coped with the threat, but I realized my friends would never agree and that dad wont be very happy with me if i let anything happen to my new 'brother' before he gets any training. With a sigh i uncapped my pen and my faithful pen, Riptide sprung free in all its pride and glory and Cooper, his two pistils . We quickly scanned for any other monsters before attacking, just as the Minotaur was about to chop my 'brother' in half, who, might I add, clearly didn't have a brain as he chose to stand still as the Minotaur swiped. I pushed back and he stumbled, looking with fury at whoever dared to stop it from its should have been easy kill. When he looked at me, recognition passed through his eyes and he charged at me. Once again i jumped out of his way just as Jason called down a bolt of lighting, and Annabeth turned visible and impaled the monster straight through the head, as Cooper was shooting him from a distance, after 2 minutes a bullet finally found its way into that tiny brain of his. Before he had even finished dissolving into the golden dust, Annabeth had turned and aided my brother to his feet. He looked around, amazed as we lead him through the camp barrier and into the watching gaze of Chiron, who simply waited until we reached him and began telling him what happened. When the campers gathered around they turned to him and just one question was being repeated in all of their heads, Who was this boys godly parent. I was about to step forwards and tell them when a trident appeared above his head, glowing a powerful sea green color before disappearing. In Its place stood my father. We all immediately fell to one knee and bowed deeply to him before he told us to Stand up

Poseidon POV

I watched all the campers fall to one knee and bow before me, all incredibly in sinc after the effects of the last War left them closer to each other than ever before. Among the campers were several Romans who, after the war, decided to stay in Camp Half Blood and help with the rebuilding and exploring the Greek ways of life. I told them to rise and then started to introduce my son to them " everyone, welcome my son David into Camp Half Blood! He is a worthy son, and i expect you to train him hard to make him a talented warrior. Give him no special trea..." as i was finishing the sentence a wierd feeling came over me and i started to feel like I wasn't in control anymore. A sudden leap in my blood circulation made me jolt my head before continuing" give him no special weapon! But i expect him to be treated well from all of you, and i want him to be made the head counselor of my cabin so he can choose the level of his training." As i said this many spasms went through my body as if i couldn't properly control it. I gazed around at the faces without nonrecognition before giving David a smile and teleporting myself back to Olympus, my body suddenly back under my own control. I shrugged my soldiers and got on with my work

Davids POV

I looked at all the campers staring at me in shock and smirked. I now had a place of power among these people and it seemed like my dad was pretty powerful. Grinning, i turned to that blonde who has 'helped' me defeat that monster. I casually said " thanks for helping me defeat that monster Minotaur thingy but i didn't really need any help, I had it under control. You are really beautiful by the way, so, whats your name?" I smirked as i saw her frown at my Minotaur comment dissolve with a blush when i called her beautiful. Looks like i had a admirer!

Cooper POV

what is with this Guy yes and even then I can't for 10 minutes and already have an ego bigger than Zeus him self. That's when I saw him flirting with with Annabeth my brothers girlfriend, I so wanted to punch him in the face for that, and from Percy's face he wanted to do the same

Percy POV

I looked angrily as David flirted with Annabeth and was shocked when i saw her blush. I was relieved that she didn't answer his question, but was confused at why my dad seemed so fidgety when he was talking, why he didn't seem to recognize anyone and didn't even look at me. I was quite honestly amazed that he gave David the counselor position. I didn't mind of course but he could have warned me first at least. Yeah, my dad was acing quite strangely. Chiron quickly put the campers back to training and chores before taking David to see Mr D. I headed of to get back to work, this had been a interesting day...

So there it is! Please review, I want to know how ive done and if I've set the scene well or not. I would like to point out this is just the opener, a slight insight to whats to come, so that why it may seem a bit slow, it'll speed by next chapter, promise. So yeah, R&R please, and cya next chapter
