Alright, so I do know that there are a lot of other stories out about what happens in the Son of Neptune, but I already have the idea for this story in my head so I'm going through with. I do use a lot of the names mentioned in Rick Riordan's two Greek mythology series but I also have quite a few new ones too. Read, review, and enjoy!

Chapter 1

Jason had disappeared only yesterday but already almost all of the Roman Army was getting nervous. As our commander there was no way he'd just leave without a word to anyone. And I was pretty sure he couldn't have gotten kidnapped by just anyone unless he was feeling quite stupid. But it's my duty as Lieutenant to stay calm even if the rest of the army can't.I thought, besides, he's one of the best fighters around, whatever mess he's in, he'll manage somehow.

Then my alarm blared to life, the morning briefings were in twenty minutes and Lupa would punish anyone who felt she could get away with tardiness. I scrambled to get on my 'casual' piece of armor (though really it was just slightly lighter than ordinary battle armor) along with the three weapons I carried daily. Then I quickly checked my laptop for any updates from Jason's search party, but surprisingly, there was nothing. You'd think finding the King of the God's son would betoo easy.

Since electronics attract monsters, our she-wolf leader Lupa wasn't too crazy about the idea of demigods having them. She had always believed that us Romans could win with the weapons our ancestors had created and passed down to us. But after a lot of kids protested that our fort was impenetrable, besides the fact that all of the demigod soldiers could use the extra practice; she was eventually forced to agree and the children of Vulcan took it from there. Now the whole place runs on their contraptions and advanced electronic generators.

I hurried through the halls and into the Captain's Room. There was a large wooden table with war fire burning in the center. Behind each chair at this table were statues of the godly parent of the child who usually sat there. They all had firm, otherworldly expressions on their faces to 'help us realize just how inferior we are compared to them' and above these were murals about the same gods. Usually the room was one of the quietest in the entire base since few people were allowed in, but that day all the captains were busy arguing except for Somnus' Captain, who was somehow snoring away.

My only hint was that in one corner of the room a boy stood scratching his head, clearly looking confused and nervous. Not that I could blame him when his fate was being decided by fully-armored, screaming teenagers.He had dark brown hair and sea green eyes, like mine, though I was positive that I couldn't have seen him before. Then why does he look so familiar? He couldn't be that boy from those visions I keep having, could he? Nearby, Mars' Captain, Dereck was shouting something about amnesiacs being worthless to strong warriors.

I snapped my fingers in front of the Somnus kid's face. "What's going on?"

Every captain immediately froze and formed a neat line, then saluted me. "Good morning Lieutenant Reyna, ma'am," I nodded in approval.

"Sorry Reyna, we just don't know what to do with that new demigod. We found him out nearby while looking for Jason, but he doesn't seem to remember who he is. And Dereck isn't helping by saying we should just execute him immediately." That was Venus' Captain, Dakota, a close friend of mine who I usually allowed to be less a little formal than customary.

Everyone must be really worried about Jason to be this off.I folded my arms, "alright...but I don't see how it matters that he's an amnesiac, we've allowed it before. He can fight without his memories, just send him to-" I glanced at the new guy again; he really did look like the boy from those dreams. "Actually, I've been having a lot of visions lately, and he's been in them. He is Percy Jackson, age 16, and a son of Neptune." The gods have been sending be visions to help this demigod? Okay... what's so special about this kid?

Everyone blinked repeatedly in surprise; it was very uncommon for anyone to receive visions since the gods rarely bothered contacted us except to do their dirty work. Roman Gods just did not like to deal with their children often. It was just a stroke of luck that the Roman Army had stumbled upon my new half-brother and decided not to kill or send him to Hall Mercury without a fuss like they usually do. They were probably too busy worrying about Jason to concentrate. Commanders just don't disappear into thin air.

Before anyone could protest to it, I motioned Percy to the guest's seat since there was no way I could get away with leaving so soon. During the morning briefings I told everyone about the current facts about Jason's whereabouts (which were few and hard to come by) and how training was going with legions one and two. Meanwhile, Dakota told her sibling to clean up Neptune's Evocati's room and bring some new clothes for Percy, because that dirt-coated shirt needed to go. I left the captains to debate about who would take over my training schedule for the day, glancing back to make sure Percy followed behind.

Percy better be ready to fight with his amnesia because I always have to prove to the others that children of Neptune aren't weak. If his amnesia gets the best of him we'll have a problem. Mars kids are always trying to 'prove their point' that Neptune is even weaker than Ceres."So Percy, this is the Roman Army, the advanced group of demigods who train to fight any threat to us or the Roman Gods. As you've hopefully figured out, the Roman Gods you may have heard about in school are alive and our demigod ancestors who live in Rome have passed down their battle strategies to us. Also, the great Roman heroes like Ulysses and Hercules actually lived and did many of the incredible things they are known for.

Percy snickered at the craziness of it while my back was turned, then quickly looked away whenever I glanced at him. "Anyway, these are the Roman Caves, though we demigods call it 'The Den.' Our current base is here in the Santa Cruz Mountains, about 75 miles south of San Francisco. There are 30 halls, though some are only honorary, carved into these mountains.

I took and deep breathe and we turned right towards the dining room. "These 30 halls, one for each important god or goddess, like Hall Neptune, Hall Mercury, et cetera, each have their own special additions relating to the aspects of the godly parent whose children live there. The soldiers here range from age 6 to 17, mostly. Just be ready to get used to all of our battle training and our everyday lifestyle."

Percy looked straight at me, "battle training?" Hope he's ready for the gladiator fights and other stuff we do down in the Coloseum.

I opened the door to the dining room. The children of Ceres were running around madly: grabbing and cutting food as fast as possible. There was probably was a show on Food Network that they 'had to watch' or something so they wanted to get dinner ready early. The vast room was one of the few that were so obviously a cave, with stalagmites hanging down and rock walls. Though there was also a serving table on one side with four huge tables in the middle for kids to eat at.

It took almost five minutes for the Ceres Captain to notice us, after she tripped and fell right in front of Percy and me. Then she gaped, wide-eyed at me, "Miss Lieutenant Reyna, sorry. Do you need something?"

Percy's stomach then growled ravenously, so no more needed to be said to Lily. Thought so Jackson, you could've at least said something since you probably haven't eaten in days.The small captain of Hall Ceres quickly asked whether the newest demigod wanted hot or cold cereal and soon Percy was shoveling fruit loops into his mouth like there was no tomorrow.

My walkie-talkie beeped, it was the Minerva captain. "Lieutenant, sorry to disturb you right now but Dereck is threatening to send his sibling out on a rampage if Hall Mars isn't in charge of your legions' training for the day."Poor Captain Hazel, the Mars kids think they're so important because their father was also the father of the founders of Rome. They always cause trouble when Jason and I aren't around.

I breathed deeply, "Put me on speaker... Dereck if you do not shut up, get over yourself, and do something non-destructive right now I will personally drag you over to Lupa's quarters and let her decide your punishment." Everyone who heard was dead silent, last time Lupa had punished a child of Mars the kid was ordered to unclog the plumbing system with his fingers (and our plumbing makes the dirtiest dumpsters look clean).Everyone was already pretty annoyed at Hall Mars beside me, Hall Mercury, Hall Somnus, and surprisingly, Hall Minerva. Jason lost it after they stole a flamethrower and torched Hall Jupiter. They seem to have lost all care about what other people think of their behavior because they were too mad about not getting to fight the titans. But that was because they attacked some nearby scientists in full body armor. With their old Roman swords and shields in hand the idiots began yelling and brandishing their weaponry until the poor scientists ran away screaming. Later that night the press got a hold of the story and broadcasted it to all of the United States, including the monsters. So, as punishment they had to stay behind and guard the base from the various monsters that were sure to attack while the rest of us were gone.

"Do you want something too, Reyna ma'am?" I shook my head and began filling out the paperwork for Percy that one of the captains had handed me on the way out of the meeting.

So I used a lot of Roman names, though I'm pretty much required to since I'm writing something like this.

Jupiter - Zeus

Somnus - Hypnos

Mercury - Hermes

Venus - Aphrodite

Vulcan - Hephaestus

Minerva - Athena

Ceres - Demeter

Mars - Ares

Neptune - Poseidon

Hercules - Heracles

Ulysses - Odysseus

war fire - Greek fire
