Chapter 4 The Horse Vs. The Boar

Reyna walked into our tent to tell me that Lord Mars has come to challenge me to a fight! I sat there hoping she was going to tell me Lol Jk I just came here to check on Caitlin! But not of course not I gave Percy a look and said "Percy what am I going to do Mars is the god of war and I'm and inexperience demigod!

Percy looked at me in concern then he stopped and I could see the light bulb going off in his head when he said "If he wants to fight you he can fight me as well, I will not let him hurt my only sibling!"

With that we walked out of the Infirmary leaving Caitlin to one of the Apollo kids who was going to bring her down in a wheel chair. As we walked to the arena I was very nervous thinking what if he kills me is Percy really any match for Mars. Percy seemed to be deep in thought but not scared at all he looked so calm like the Ocean. Then before we walked in there he pulled me to the side of the arena where we were alone and said "Listen you have to be careful Mars will just tempt you to do something rash he will try to anger you stay clear headed and remain calm together even though he is Immortal we can still kick ass!"

With that brightness I felt confident for the first time. As we walked into the Arena it went silent I think all the Campers were here or at least more than half anyways! Mars was sitting there looking bored and then he saw us he stood up and brought out his sword which was a roman gladiator sword which I have to say looked rather bad ass! He pointed at me and drew the kill sign across his neck and I cringed then Percy elbowed me in the ribs and whispered "Show no Fear!"

Lupa came forward and announced to me liked I didn't know that Lord Mars was here to fight me and asked do I accept his challenge! I looked at the wolf then at Mars and said "I accept your challenge on one exception if you agree to it!" Lord Mars nodded and Percy took out his sword looking like a complete G and I said "If my brother can fight by my side seeing as I am his only sibling he wishes to fight with me so at least if we die we die together!"

Then Lord Mars looked at me and laughed while saying "Well looks like Neptune will not be happy with me when he finds out I killed his two favorite sons. But I accept your challenge this is a good chance to kill you both in one swoop"

Then I clicked my trident necklace and said "Then let this fight be to our death and until you are incapacitated!"

Then Lupa said "By the power of Rome Lord Mars challenges Percy Jackson Praetor of the first legion and Orion O'Connor son of Neptune. This fight is to the death Begin!"

Lord Mars sat there and circled us for a while like determining what are weak points were. I sat there thinking I've always been a decent swords man but he's the god of war is there anyway we can even stand a chance to him. Percy looked at me and smiled and started twirling his sword riptide to a nice steady beat then I decided to do the same. Mars looked unnerved by this and said "Whats wrong Orion afraid that when I win Kevin will go back to Caitlin's room and finished what he started?" I was pissed but I reluctantly looked at Percy who gave me a look that said lets attack him together. I nodded and then we both charged forward! Lord Mars was definitely skilled he dodged and parried us and and then kicked me in the chess after a few seconds I hit the ground hard and my sword went half way across the arena. Percy was holding his own then lord Mars tried to stab Percy and I cried out but then the sword seemed to bounce off Percy! Everybody gasped and Lord Mars looked like he just remembered something.

Percy laughed and said "O did you just remember that I was invulnerable well that sucks for you doesn't it!" I was in a daze and completely amazed. Percy dodged and parried long enough for him to yell at me "Hello this is still your fight get up and get your sword and come help me!" This snapped me out of my trance and I ran to my sword picked it up and ran to Percy. We dodged and parried until Mars disarmed Percy and tried to stab him but stupid me forgot he was invulnerable so I took my sword and decided to fight him one on one. I dodged and parried and swung at his head and then I got him lower his sword and he said "Not bad to bad I'm going to half to kill you. You could've made a great swords man and demi god!" Then Mars made a fatal move he lunged at me but I sidestepped and clothes lined him and he hit the arena mats hard! I kicked his sword out of his hand and then I aimed my sword at his throat he was just about to try and fight me until Percy had his sword pointed to his throat as well. Then Mars swallowed hard and said "Looks like you've won this one but next time your invulnerable brother will not be there to save you" Just before he disappeared I gave him a nice cut across the face and said "Well I was the one that officially kicked your ass and looks like you and your son can match now!" Then I saw the golden light so bright I looked away! I forgot that the crowd was their and I looked out to see Caitlin beaming at me which made me smile as soon as I did this everyone except for a few people who I'm guessing were sons or daughters of Mars started cheering!

I looked at Lupa and she said "Well congratulation Orion looks like you just found your spot at this camp in First legion!" I was so happy I could've yelled in joy then Percy came and gave me a pat on the back and gave me the I'm proud smile and since I never had a dad this made me very happy! Then Lupa looked at Caitlin and said "You as well since you being a child of Pluto and proper training you will become very powerful as well you will be put in the first Legion!" Then Caitlin gave me a smile that could've lit the dark side of the moon!

People were starting to clear out except for some of the people I knew Reyna, Percy, Caitlin of course and then there was Ian Brock who was the son of Mercury who I started to talk to earlier that day when I was waiting for Caitlin to come back around he was a pretty cool guy. He had been knocked out earlier that day by a son of Mars. They all looked at me with bright smiles so I had to say "Well looks like the Mars cabin will be laying low for a little while after I kicked there head councilor and there father ass!" Everyone laughed at that but then Percy said "Looks like me and you have some training to do so if Mars comes around when I'm not around you can still kick his ass without a little help" I gave him a serious look and then I went for hug. I knew this hug silently said a lot like thanks for having my back and thanks for everything that you've done for me and what you will do for me!

A little while later after everyone had left and it was just me and Caitlin in the arena sitting there in a comfortable silence. You see since we have known each other for so long we are comfortable enough to remain silent around each other. Then I saw her tears form up in her eyes. This disturbed me and I asked "Caitlin whats wrong aren't you happy? You got a sister now your in the first Legion with me and the others."

I didn't understand but then she finally said "I was just so scared for you I can't lose you. Please just promise you will be careful when you are training with Percy and when you get into fights!"

I looked at her and said "Caitlin I love you and will never leave you on my own free will!" Then she stood up out of her wheel chair and sat in my lap. Then she kissed me like she never has before with passion and desperately like it was the last thing she was ever going to do. We sat there for a while and just made out but then it started to get intense and it started to go a little farther I stood up and she lapped her legs around my waist and I laid her down on the bleachers. I stuck my hand up her shirt but then I came back to realization and said "Stop I will not take advantage of you like that. I love you and believe me I want to but I don't think we are ready. And we are still young for gods sakes babe were only 15."

I looked at her desperately and she sighed and said "Your right were to young to do this and we still have the rest of our lives together there is no point to hurry I'm sorry if you felt like I was pushing you into this. Its just after that jerk laid his hands all over me and kissed me I feel like I need to be with you more."

I looked at her and smiled and said "Look that deuchbag touched you and he got what he deserved. I should've killed him for touching you like that but you don't have to prove anything to me you just proved it right there I know you are loyal to me and that's all that matters." She smiled at me then I held out my hand and we walked out of the Arena together.

Once we got to our cabins I kissed her goodbye and said good night. Once I was back in my cabin Percy was waiting for me. I stood there and we said nothing in silence and then I had to break it and say "Percy whats wrong?"

He looked at me and said "Lord Mars was a lot stronger than he was before last time I took him easily but back there he would've killed me if not for you or more like would've found my week spot." This didn't really bother me because I figured gods could get more powerful so why not but Percy seemed so determined something was wrong.

I walked over to my bed (by the way my bed is right next to Percy's) and faced Percy and said "Look lets just hope that somehow hes gotten stronger or something because after somethings that I've heard about the second titan war" As I said this Percy fell to the ground and screamed in pain. I ran outside my tint and yelled "HELP" I picked him up and took him outside at this point I saw a few people running our way but then I decided the best thing I can do for him is to take him to the water.

I got to the water and dumped him in but the second he touched it his eyes opened I went under water with him and asked him "Are you okay man?"

He looked at me and said "Dude your not going to believe this but I remember everything."

Now I was just confused "Did you forget something or what?"

"Dude I'm going to be honest with you I don't remember anything before a month ago I woke up a few weeks ago in our cabin with no memories. When Reyna came to me she said Percy what are you doing you missed lunch I looked at her and she looked really familiar but I couldn't place a finger on it. But now it all makes since."

I looked at him like he was crazy but then he continued on "I'm not the real Praetor of the first legion and I'm not really Reyna's boyfriend but I am still your brother." I was still confused "Let me explain I didn't come from here I came from another place camp half blood its where they train the Greek demi gods unlike you your a Roman demi god. All these memories man the mist they put them here the things I kind of started to remember over time. They were fake memories, memories that would match some of the other Romans here like Reyna's."

I stared at him I couldn't believe not that he was Greek I didn't care about that but all his memories were false and now he has all his old memories and I guess he still has all the ones since hes gotten here. Then a wave of realization hit me then what about Reyna and everybody else if he wasn't the real Praetor then who was? So I decided to ask "Then who is the real Praetor"

Percy's face darkened when he said "Jason Grace son of Jupiter!"

"But then if you just got your memories back then did everybody else?"

He looked at me like this disturbed him and so then he said "Lets go find out."

When we got out of the water we were surrounded by Roman demi gods and they did not look happy and then Lupa walked forward and said "Percy Jackson son of Poseidon surrender yourself or be destroyed"

I looked at Lupa with rage and said "If you touch my brother Lupa I will stab and slash until your immortal essence has to find another host" As I said this a giant tilde wave came up in the back ground. Then the last person I expected to show up showed up. It was my father Neptune or Poseidon. He looked at me and said "Calm down Orion the gods have allowed me to come down and explain all of this mess. Before you speak Lupa let me talk first." He said with a dangerous tone in his voice "My son will be the symbol along with Jason to bring the camps together and fight side by side because unlike your Greek counterparts they have already discovered our new enemy and they look Kronos look tame." Everyone started talking at once and Neptune held up his hand and everybody went silent so he continued "If you'll do not become allies with your Greeks siblings then the Giants will destroy all of us."

He then looked at me and said "Orion you and Percy will unite that camps if the Romans decide to accept it then we will be one step closer to defeating the giants."

Then Reyna stepped forward and said "Wait you can't possibly be talking about the same giants I'm thinking the 12 giants that almost killed all of you after Kronos did the first time. Like Porphryion?"

Neptune nodded his head greatly and now everybody was to stunned to talk then he said "Look these people are good at heart and good warriors while you'll were toppling the black throne of Krios Percy led the Greeks into battle against Kronos and his army."

Percy finally said "I single handedly beat Kronos back to the gates Tartarus." Everyone gasped at this news.

Neptune continued "Hera's plan required an exchange of leadership Jason has already been accepted and they know who he is. The Greeks are working on a ship called Argo II to come here and hopefully make peace and then take the seven of the great prophecy to Greece! If they can accept Jason you'll should be able to accept Percy his fatal flaw is known to some and not others but all of my children have the fatal flaw of Personal loyalty."

Then the stupidest person I have ever heard probably a son of Mars came up to the front and said "How do we know that they just didn't kill Jason off"

This seem to really piss of Neptune because his eyes turned sea green and he grew a couple of feet taller and said or more like bellowed "You dare call a god a liar?" Then the biggest wave I have ever seen grew out in the distance.

I looked at my dad and said "Dad calm down I don't think he meant it like that."

Neptune sighed and went back down to normal size and the wave went back into nothing. But then Neptune said "I swear on the river Styx the Jason Grace son of Jupiter is alive and healthy and is planning to come her and return with some Greek demi gods." Thunder boomed in the distance "From here if you'll decide to join them you'll will sail to Greece and fight the Giants at the doors of Death which is the largest gate to Tarturus in Greece." Neptune froze and then said "The gods require me back on Olympus for now Olympus is closed off but my brother will soon re open it." With that he disappeared into a bright golden light,

Percy looked up at Lupa expectantly then she said "The son of Poseidon will be spared he will remain in the Neptune bunker but until further notice Reyna will be Temporary Praetor of the first Legion. Perseus you will remain in the first legion." With that she looked at me like she was about to say something but I guess she decided against because she growled and walked away. After a while everybody walked away talking about Percy only me Caitlin Reyna and Percy of course stayed behind.

Reyna walked up to Percy and said "I'm sorry but we can no longer be together but either way I still want to be friends because these last few months of memories aren't fake and you are still a good person."

She looked at him hopefully and then he said "Its okay I forgive you even though there is nothing to forgive but I know why you were easy to fall for."

Reyna looked at him and had a sly grin on her face and said "You mean it wasn't my dashing good looks?"

I laughed at this and Caitlin and Reyna glared at me Percy kind of chuckled and then said "Well that's a part of it but I have a girlfriend back at camp and she is also a rather short gray eyed daughter of Minerva or Athena her name is Annabeth."

Reyna looked sad and relieved at the same time but then she smiled and gave Percy a hug and ran off to her cabin. I gave Caitlin a goodnight kiss for the 2nd time I guess it was only like 12:30 so its still not that late but we all have to get up at 6 so I guess so I looked to Percy and said "Well looks like we better go to bed."

He smiled walked up to me and gave me a hug and said "Listen no matter what happens you are my brother and nothing can change that." I was kind of surprised but you know what else was I supposed to do. So we walked back to our Cabin and then almost as soon as my head hit the pillow I feel asleep.

Dream sequence

I was looking down at two people who were sitting in front of a fire place I could make out one of them she was about average sized for a woman but she was really dark not in skin almost like her aurora around her was dark. The other was guy though I couldn't really see him but he was huge. The Girl spoke first "Looks like Camp Rome has finally discovered our plan so now ¾ of the demigods in the country are on high alert."

The Giant I'm guessing who he was said "Who cares they do not stand a chance against us once the Romans and Greek meet again they will tear each other apart and then the gods will be weakened because there children couldn't figure out who the real enemy was."

"But still what if they don't fight what if they-"

"Nyx you may be powerful but do not question me they will fight and they will kill each other I am almost sure of it."

The woman said again "I'm sorry my lord I didn't mean to insult your intelligence I was merely suggesting the possibility."

The giant seemed to think this over well I am not the true king of the Giants anyways once we raise my brother we will hopefully have my mother raised so those idiots won't be able to fight the Earth itself"

They both laughed at this but then Nyx froze and she said "Master I believe we have a unwanted visitor"

The Giant stopped laughing and roared

I awoke with a start and looked at the time and then over at Percy's bed and it was Empty. This scared me so I ran to the window and looked towards the beach and saw Percy sitting there I decided that I would leave him to his thoughts for now. But it was 530 so might as well stay up now. I couldn't sleep after that dream anyways it was so realistic.

(A/N) Looks like Orion hasn't figured out that demi gods have dreams that could be happening in the past present of future looks like someone forgot to mention that! Maybe Neptune and Orion have a chance at becoming at least some kind of allies he will pop up more in the story as I goes on. And Mars was a bit more powerful than before and now the truth is out about Percy. Lets just hope that the Romans accept Percy as they did Jason at the Roman camp. So yes there is more plot to this than just bringing in a few new demigods I will go two more chapters before the quest starts and you'll will just have to be patient until then. Looks like Percy has been smooching off of Jason's girlfriend for a while I don't think he will be happy to here this. For now I hope you Enjoyed. Please Review! By the way I will change a few things since this a alternate Universe please do not forget this and freak out.
