"So, who is your companion" I asked gesturing towards the boy. She looked over at him and smiled.

"Oh, that's Jason. Jason Jackson."

I looked over at Thalia and saw a few tears in her eyes. I stepped towards Jason, "Jason, it's us. I'm Percy and that's Thalia" I said.

He looked shocked before pulling me into a hug. Thalia quickly joined in as well.

"Woah, woah, woah, you guys all know each other too?" Reyna asked confused. I pulled away from them and nodded, "This is our brother. Our mother said he was dead when we were four years old" I said sadly. She nodded, not expecting that.

"So, who is your godly parent?" I asked him.

He looked over at me and smiled, "I'm a son of Jupiter, I assume you guys are as well" he asked.

I looked at Thalia confused. "Jason, do you mean a son of Zeus? I'm a daughter of Zeus, and Percy is a son of Poseidon" Thalia said. I nodded agreeing with her.

Reyna gasped, "are you Greeks?" she asked pulling out a sword. Jason pulled out a coin. This was all too much to process. Reyna said she was a daughter of Bellona, and Jason said he was a son of Jupiter. That's when Athena's lectures came back to me.

"Yes, we are Greek, and you guys are Romans. I know the history that comes when Greeks and Romans meet up, but remember last time Reyna? We were fine together" I said confidently. I then brought out my coin, and Thalia did the same, "I also bet that when you flip that coin it will turn into a sword or a spear right Jace? Me and Thalia have the same one. We are full blooded siblings, there is no way I would ever fight you" I said seriously.

They reluctantly lowered their weapons, "alright, we can catch up and explain more later. For now, we should enter the garden and get passed ladon, so we can set up camp and be fully rested for tomorrow" I said.

They nodded cautiously and followed me up the mountain. Eventually, a huge tree came into view. I saw the golden apples and ladon slithered around the base of the tree sleeping. I heard Jason gasp, probably just now noticing the giant dragon coiled around the tree.

Four figures shimmered into existence and I scowled at them.

"Perseus Jackson you are foolish for returning here, leave now and your life will be spared" they said in unison.

"How about this, we stay here, and I kick your immortal asses just like I did your fathers" I said confidently.

"You barely defeated him with the help of that worthless goddess, nevertheless you don't have her this time" the one in the middle said.

I glared at them and they began shimmering out of existence when they called out, "Ladon wake."

"Shit" Jason said. I chuckled at that.

Reyna took out her sword, and I saw Thalia with her sword out as well. Me and Jason both had our spears out. "Don't attack directly. Try to skirt around it, and only attack if it attacks first" I said. They all nodded, and we began making our way forward.

Jason and Thalia led the way. It was a slow process, but it was working, Ladon wasn't attacking us. Right as I thought I had gotten out of its reach I heard a scream.

I whipped around and noticed that Reyna was surrounded, and fending off a dozen heads. I cursed and sprinted over.

A dozen heads lunged at me, but I swatted them all away with my spear. I saw one lunge at her from behind and my instincts took over. I pushed her to the ground with the blunt end of my spear and the head snapped its jaws around my spear.

I kicked it off and then swatted it back. I pulled Reyna up and pushed her in the direction of Thalia and Jason. After a second we were out of its reach again and panting.

"Are you okay?" I asked her.

She looked at me in amazement, "you saved me again Percy" she said pulling me into a hug.

"I told you I would do it a hundred times" I said smiling. Jason looked surprised that she hugged me. We walked a little farther up and set up camp for the night. I found some wood and threw a fireball into it starting a fire.

Jason looked dumbfounded, at this. "You have to tell me everything" he said smiling.

I nodded and me and Thalia told our story.

It took forever, but we finally got through everything. He looked at us both shocked.

"So, you're invulnerable?" he asked skeptically. We both nodded. "Wow" he said in wonder.

Thalia looked over at Reyna, who was sitting rather close to me. Not that I was complaining or anything. "So, you're the famous Reyna? My brother has told me all about you. He never shuts up about you" she said smirking.

I blushed at that, and I saw Reyna did too, "shut up thunder thighs" I said scowling at her. She smirked so I threw a small ball of fire at her. She scowled and patted it out, throwing a glare at me.

"Dude, it is so cool that you can control fire" he said, as I laughed with Thalia.

I nodded, "yeah, Hestia's blessing is amazing" I said. "Tell us about your journey now" I said, changing the subject off of me and Reyna.

She looked at me gratefully and grabbed my hand. We all spent the next couple hours reminiscing together.

Eventually Jason and Thalia drifted into a conversation of I don't even know what, probably some children of Zeus and Jupiter nonsense.

I noticed Reyna look up at me, "I really do owe you my life Percy" she said seriously.

I smiled at her, "no you don't, I like you Reyna" I steeled my nerves. "you're my friend, and you're different than any girl I have ever met" I said seriously squeezing her hand.

She looked directly into my eyes, "I really like you too, but we're from different worlds" she said sadly looking away, and just like that the moment was over.

"Yeah, I guess you're right. Maybe not forever though. I swear on the river Styx that someday we will be able to be together" I said as thunder rumbled above us. She looked back over at me surprised, but smiled. She leaned up and our lips met in a kiss.

This one lasted longer than the first, and was amazing. A few seconds later she pulled away and laid her head on my chest. I looked over to see Thalia smirking at me.

I cleared my throat, "yeah, uh Thalia, what happened when you lightning traveled here earlier? Why did it take so long for you to IM?" I asked avoiding her eyes. Reyna looked over to her curiously as well.

"I got here and nearly passed out. I was then attacked by the gorgon sisters. Thank god it wasn't medusa though" She said to my shock.

"Anyway, I ran for a while, until I found the strength to fight. I defeated them easily and then called you. Shortly afterwards, I found the entrance to the garden, and saw an army of monsters. That's when they showed up. Shortly thereafter you showed up" she said yawning. "I'm gonna hit the hay. Big day ahead of us. I suggest you all do the same" she said getting up and going inside her tent.

Jason followed suit, and Reyna was about to follow, but I pulled her back down. She chuckled, "Percy I'm tired" she complained.

"Tell me your story now, I don't know when I will see you next after tomorrow" I said seriously.

She sighed but told me anyway. After Hephaestus' had transported them to California, she told me her sister went her own way to join the Amazons. She found Lupa though, and made her way to camp Jupiter. A demigod camp for Roman demigods. I smiled, happy that she had a home like we did. She told me how she made it into the first cohort and was now the centurion with Jason. I'm not sure when, but it got quiet and we just laid there enjoying each other's company.

Line Break

I was rudely woken up by someone saying, "Oh Percy you dog, what do we have here?" I cracked open an eye and saw a mess of black hair on my chest. The night's events came back to me and I realized we must have fallen asleep at some point.

I glared at Thalia mouthing a phrase to her that would surely get me smacked if my mother had heard me say it. She just laughed, and I felt Reyna stir on my chest. She opened an eye and looked up. She smiled at me, then noticed the position we were in and quickly got up. I followed suit.

She glared at me with a blush on her face. I held up my hands in surrender saying, "nothing happened last night, we just fell asleep after you told me your story."

She nodded and looked relieved. Jason came out then and saw us blushing.

He smirked, "alright, well let's get this over with" he said.

I nodded. I took out tidal wave and flipped it catching it in sword form. Jason followed suit, and Thalia had her spear out. Reyna took out a sword and we made our way up to the titan stronghold.

When we arrived, I threw a fireball at the door, blasting it to pieces. I saw a small army of monsters, and an even smaller army of traitor demigods. Luke, Silena, and Beckendorf among them.

I charged at the demigods and knew my companions had joined the fight as well. I clashed blades with a guy with an eyepatch. I kicked him back and slashed at his head which he blocked. I feinted a strike low, then reared back and punched him in the face. His nose erupted in blood and I slashed him across the chest before he could react. He fell to the floor clutching his chest. I looked around and saw Silena and Beckendorf knocked out, and there was no sign of Luke.

I heard clapping in the corner. I looked over and my blood boiled. I saw Perses standing there arrogantly.

"I didn't know you were this foolish Perseus. Did you learn nothing from our last fight?" he asked arrogantly.

"My powers have doubled since we last met Perses" I said more confidently than I felt.

"Good, I wouldn't want to make a mess of things in front of your siblings, and your little girlfriend" he said with a smirk.

"This is my fight Thalia, go help them" I said to her. Perses chuckled, "I love your arrogance young Perseus. Don't fret though, my brother Krios will be more than happy to take care of your sister" he said as a new being stepped out of the shadows.

I looked back to see Reyna and Jason finishing off the monsters.

I knew there would be backup soon, but that was my least concern at the moment. I said fuck it and charged at Perses.

I ducked under his javelin and slid underneath him, tripping him up in the process. I got to my feet and slashed a small cut in his back. He growled and got to his feet.

He looked at me with hatred, and we went back and forth. Neither of us able to gain the edge over the other.

I saw Jason helping Thalia, and noticed Reyna approaching from behind. I spun around his attempt to stab me and blocked Reyna's strike, much to her and Perses shock.

"This is my fight Reyna, help Thalia and Jason" I growled. She looked like she wanted to argue but nodded when I glared at her.

Perses looked at me with newfound respect, "I respect your courage and honor in battle. Most wouldn't have done that. Unfortunately, you will still have to be killed" he said, smirking at the end.

I just raised an eyebrow, making him scowl. He charged at me and we engaged in battle once more.

We were deadlocked, neither could even make a scratch on each other. I slashed, stabbed, swiped, and nothing. Each one was defended by him. He was getting angry now too, since I was defending all of his strikes as well.

He locked our blades together and punched me in the face sending me flying back. I looked over and saw Krios kick Reyna into the wall, and she crumpled to the floor in a heap. She was moving, but she didn't seem able to get up.

Perses eyes followed mine and he got a sadistic grin on his face. He started towards her, and this sent me over the edge. First, she gets hurt, and now Perses is going after her while she is defenseless.

I got to my feet and launched myself at Perses as I let out a scream. We were both sent to the ground.

We got to our feet and I sent an onslaught of powerful strikes at him that he was struggling to defend. He looked like he couldn't believe the power I was putting behind each strike.

Time seemed to slow down, and I could read his every move. I saw him about to stab at me, so I willed my shield into my arm, and dodged the stab, locking his javelin between my body and my shield.

He looked shocked that I read that move so well. Anger was all I felt at this point. I slashed my sword downwards and his javelin snapped like a toothpick. He didn't get over his shock quick enough, and I bashed him in the face with my shield. Without wasting any time I swiped my sword across his neck. He looked down in shock, and then dissolved into nothing.

I turned to Krios and got ready to charge, but he must have noticed that I destroyed Perses, because he stepped back.

"One day Jason Grace, you won't be so lucky to have Perseus by your side" he growled out, before flashing away.

I almost fell to the floor, just now realizing how exhausted I am. I then remembered Reyna. I sprinted over to her and slid onto my knees next to her. I cradled her head on my lap.

"Rey are you alright?" I asked. She opened an eye and looked like she was about to speak, but couldn't get it out.

"Yo..you saved me again" she stuttered out so quietly I barely heard it. A lone tear came to my eye. "Thalia" I barked. She was at her side in a second and started healing her. Eventually, color returned to her face. Apparently, she had broken a couple ribs and could barely breathe.

I picked her up, and teleported out of the garden. Thalia reappeared with Jason a moment later. "We can rest here for a while, and return to our respective camps when we are all well enough" I said, not leaving it up for discussion.

I stayed by her side the rest of the day. Her hand always in mine, and occasional conjuring water, and healing her the best that I could. She eventual awoke and we talked about random things we wanted to do. All too soon Thalia and Jason came over. They had just woken up and told us it was time for us to go home.

I walked over to Jason and pulled him into a hug, "you take care now brother, don't get into too much trouble. Watch out for Krios too" I said to him.

He nodded, "hey you take care too. Unfortunately, I feel like even if I tell you to stay out of trouble you won't. Thalia said you tend to go out looking for it" he said smirking. I just shrugged smiling. "And don't worry, I'll look out for her too. Make sure she stays out of trouble too" he said seriously. I just gave him a grateful smile. With one last pat on the back I walked over to Reyna.

She had a makeshift crutch and she smiled when I walked over. She pulled me into a hug and I whispered to her, "don't forget what I said. I was serious too" I said. She looked at me and I knew she believed me.

She pulled me into a kiss and I heard Jason wolf whistle. We pulled apart and I rolled my eyes at Jason.

"Take care of him, if he's my brother he will surely find himself into trouble more times than he could count. He needs friends to watch his back" I said remembering all the times my friends have saved me.

Jason glared at me and they walked over. "We can't tell anyone about the whole Greek and Roman thing" I said sadly. They just nodded, and I waved one last time as they disappeared from our view.

I grabbed my necklace and prayed to Artemis. A few seconds later she appeared. "Any chance you can teleport us to camp, I really don't have the energy at all right now?" I asked hopefully.

She smirked, "sure weak boy, I will teleport you, while Thalia does it herself" she said making me scowl. Thalia laughed at that and Artemis put a hand on each of our shoulders and teleported us away.

We didn't reappear at camp though. We reappeared in the throne room where there was currently a council meeting happening.

We made our way over to Hestia's throne, bringing a smile to her face. Zeus finished what he was talking about and told us to recount what happened on our quest.

Everyone looked at me shocked when they were told that I defeated a titan, and Perses no less. My father looked so proud of me.

"I'm sorry we had to take your brother from you all those years ago" Zeus said to us sadly.

"We understand why it had to be done uncle. We also Know we can't tell anyone of the Roman's existence, at least not yet" I said, adding that at the end.

"You got along fine with them then?" he asked.

I was about to reply when Thalia beat me to it, "Percy has a Roman girlfriend" she said cheekily.

"No I don't" I defended.

"Yes he does"

"No I don't"

"ENOUGH" Zeus roared.

We both looked sheepish.

"I can settle this, he so does" I heard Hestia say above me. I glared at her and most of the council laughed at the exchange that just happened.

Zeus even cracked a smile at this, "at any rate, you guys have done a fine job and I am sure you are ready to get back to camp half-blood and continue training the demigods" he said smiling after the room quieted down.

I looked over at Thalia and knew her look mirrored my own, "how has the camp been doing under Clarisse and Nico?" I asked turning to Zeus.

He smirked, "Well it has only been a day and a half, but they seemed to push the campers harder than you have in that short time" he said.

I looked at him shocked, we worked them pretty hard. Then I thought about Clarisse and how brutal she can be sometimes and realized that it wasn't so hard to believe.

"Is that all?" Thalia asked. Zeus nodded but held up a hand, "Thalia you may leave, but I would like to speak to Perseus for a moment" he said and the majority of the gods flashed out. I got smiles from my father, Artemis, and Hestia before they all flashed out.

"I'll meet you after I'm done with your father" I said to Thalia. She nodded and disappeared in a strike of lightning.

Zeus shrunk down so we were around the same size and walked over to me. "Perseus, I would never tell my daughter this, but your power outrivals hers greatly. I am asking you either before training starts or after it is finished, if you can train her a bit in combat. I know she is a capable warrior, but she isn't at your level" he said making me look at him in shock.

I nodded slowly, "Alright uncle, I will train her to the best of my abilities in sword fighting, but I am afraid she is better or at least equal to me with a spear. I will do my best though" I said respectfully, bowing my head.

He nodded, "Thank you Perseus. Be prepared, within the next year we will be in full war mode I am afraid" he said solemnly. "Last thing, keep Hades spawn close, he will be a valuable asset to you in the future" he said before flashing out.

I just nodded already assuming as much, and disappeared in a flash of flames.

I reappeared inside the Zeus cabin to see Thalia sound asleep and snoring. I chuckled to myself and threw a small fireball at her. She shrieked and patted herself out looking around wildly.

When she saw it was me she glared at me and I saw a dark look in her eyes. I gulped and a bolt of lightning struck me in the chest sending me flying into the wall of the cabin.

I got up and dusted myself off. "Are you done?" I asked. She nodded happily with a smile plastered on her face.

I told her of what Zeus told me, and she didn't look happy about it at first, but she eventually agreed it would be for the best. Once that was over I flashed to my room and fell asleep, the only thing on my mind a certain dark haired demigoddess.

Line Break (6 Months Later)

I woke up and decided to get ready for training. We had been going even harder on them lately. We now started at five a.m. and we now did double the amount of laps for our morning jog. Everyone had moved up and out of the beginners' class. The elite class mainly stayed the same, and now the intermediate class was broken in two, one taught by myself and Thalia, and one taught by Chiron.

Since our mornings were now open, we had the Hephaestus cabin build a huge gym, as an added part of the arena, and the mornings are designated for working out. The rest of the day stayed the same mostly and we just pushed them harder.

After everyone went to bed, I trained Thalia from ten to eleven, and she had greatly improved too. She was almost to my level now, and Nico wasn't far behind. Us three were clearly the leaders of camp, and everyone looked up to us.

I realized that today was Thalia's sixteenth birthday, so the war could start at any time now. Weirdly there has been no more attacks on camp or anything. I just figured they were building their army and waiting to strike at the right moment.

In six months I would be sixteen and in nine Nico would be. It appeared we will be in full-fledged war within the year.

I heard a knock on my door and quickly threw a shirt on before opening it. I saw Thalia and she quickly explained that Chiron wanted to see us and Nico in fifteen minutes before training started. I nodded and continued getting ready.

By the time I arrived Thalia, and an irritated looking Nico were already there.

"Nice of you to show up" Nico barked at me. I just gave him a large smile and he scowled at me.

"I have called you all here because I have grave news, Typhon is rising and he will be free very soon. Perseus, I believe when you blew up Mt. St. Helens it helped awaken him and now he is dangerously close to being free" he said seriously.

I looked guilty and Nico spoke up, "What does this have to do with anything?" he asked.

Chiron sighed, "Typhon is very powerful, it will take nearly all the gods to subdue him, and that is without Poseidon, as he already has his hands full with the relentless attacks of Oceanus' and his forces. If he gets to Olympus all will be lost so we have to hope they can defeat him. The point to this though is that I am afraid you will not have help from the gods in defending Olympus, it will just be the demigods' and hunters" he said.

I thought about asking about the Romans but thought better of it. I just nodded solemnly.

"Does anyone know of your achilles curse?" Nico asked me and Thalia. I looked at her and we both shrugged.

"We have tried to be careful with it, but it is possible they could know about it, why?" I asked.

He smirked and took out a knife, "because if they do, then I could be a wild card in this whole thing" he said bringing the knife down on his arm. Instead of embedding into his arm the knife blade snapped and cluttered to the ground. I looked at him shocked, wondering when he took a bathe in the styx.

I smirked and got an idea. I would share it with them later and decided Nico needed to start training with us after hours.

After Chiron dismissed us we set out to begin training for the day.

After a few hours and everyone was drenched in sweat we dismissed them for lunch.

I sat down with Thalia and Nico and heard a hunting horn. I grinned at Thalia and saw Artemis and the hunters appear.

Most of the hunters went and sat at the Artemis table, while Zoe and Phoebe walked over to us. Artemis joined us after she exchanged a few words with Chiron.

She hugged both Thalia and I, and I gave Zoe a quick hug. "Hello Thalia, Perseus, Nico" she said giving him an indifferent look.

We nodded to her and she continued, "we will be staying at camp half-blood for the remainder of the war and the defense of Mt. Olympus. My girls will be under your command when the final battle happens, and I have a few requests" she said.

I looked at Thalia and we turned back to her gesturing for her to go on, "Anyway, they will listen to the two of you because they have respect for you. I just want to make sure that they are treated fairly here and stay out of trouble" she said looking over at Phoebe.

She looked like she wanted to respond but Thalia cut her off, "don't worry Arty, we'll make sure they are respected" Thalia said and I nodded agreeing.

"That's not all though, I want them to be included in your training as well. They will follow your commands. I want you guys to help train them in combat and help them improve, and in return they can help Chiron teach archery" she said looking at us.

"Yeah, I think that's a great idea. Not only will it help them become more versatile, but us as well. Their skills with a bow are sure to help us immensely" I said bringing a smile to her face.

"Thank you guys, they will be a valuable asset to you, I promise" she said before flashing out.

Phoebe got up and went to join her sisters but Zoe stayed around a little longer.

"Zoe how would you like to do a little extra sword training at the end of the day. I am already training Thalia and Nico to get better with a sword and it would be immensely helpful for yourself and the hunters if you joined us" I asked garnering a scowl from Thalia and Nico.

She was deep in thought for a moment, but eventually nodded. I smiled at her and she went to join her sisters. I realized that the next half a year would be extremely grueling and had only one thought in my mind:

Which one of us is going to be the child of the prophecy.

A.N. Well here's the next chapter. I know it has been awhile but I have been very busy, and I'm trying to figure out a few things for the story. It might be a little while before I update again because of school work, but once summer comes they will be quicker. I have slowed down because I don't want to make it too much like the books, and I still want to make it interesting. Next chapter will be a slight time skip, and the final chapter before the war begins. I'm going to put up a poll about a possible sequel when this story ends so go and vote on that. Let me know your thoughts on the chapter.
