A/N So first I would like to apologize for the late update. Been hella lazy. As for the pairing still have not decided, but I'm leaning toward a certain one. Not gonna name it at this time. Anyways here is the chap.

Setting: Camp Half-Blood 1:00 A.M

Annabeth sat on the beach of Camp-Half Blood absentmindedly running her fingers through the sand. She didn't show it, but the absence of Percy was constantly on her mind. The camp itself would usually be in disarray without its leader. But due to recent events, Jason has filled the void that Percy left behind.

The daughter of Athena was still worried even though everything seemed okay for now. The recent words he spoke after he completed his quest echoed in the minds of the Greeks.

"Another camp and with roman demigods…" Annabeth mused.

Ever since the defeat of Kronos, things only seemed to get more hectic. Percy went missing, a new great prophecy, and of course Thalia's brother Jason was found and they were reunited. To Annabeth, Jason is a good leader and a strong fighter, but to her she was no Percy.

"Percy at the Roman camp…" Annabeth thought as she remembered Jason's words after he completed his quest.

"But why would Hera swap Jason and Percy, what did she think this would accomplish?"

"You know it really isn't safe to be thinking so much. Your brain might just explode since you use it so much." a voice said from behind Annabeth.

Annabeth swiveled her head and smiled a bit at Thalia as she sat down next to her on the beach.

"Thinking about seaweed brain again?" Thalia asked. She knew Percy meant a lot to Annabeth even if they only dated for a short time before he was whisked away. Her feelings for him were clear to anybody who knew Percy and Annabeth before they were separated.

Annabeth said nothing, only nodding her head as a comfortable silence settled as they listened to the waves crash against the shore for several minutes.

"I just hope Jason is right Thals." Annabeth said worriedly as she hugged her knees to her chest.

"About the Roman camp? I think he is, he sounds pretty confident about it. And even if it's not in San Francisco the Argo II can take us anywhere, I hope all that wisdom in your brain didn't forget it's a flying ship Annie." Thalia teased.

"I do remember, it's just what if he's different than the Percy we know? You remember Jason and how he said he had amnesia, what if Percy doesn't remember any of us?" Annabeth confessed.

Thalia said nothing for a moment before speaking.

"I mean Jason remembered everything eventually. It's how he became so confident about the roman camp existing because everything came back to him, probably because he completed his quest and the camp recognizes him as a leader now."

"So, you're saying that was Hera's plan? To have them swap and bring the Greeks and Romans together by having them become leaders in their camps?" Annabeth asked wanting confirmation.

"Probably, Hera did seem very ticked off when she visited Jason, well at least that's what he told me. He said something about her plans not going the way she wanted them to." Thalia replied.

"Her plans? Ugh there is so much more to this than I thought. Why do the Gods have to be so secretive? Aren't we all on the same side here?" Annabeth shouted out in frustration.

Thalia shook her head laughing a bit at her remark. "For as knowledgeable as they are, even the Gods don't have the ability to do everything. Remember I was a tree for a couple years? And you know the ancient laws."

Annabeth nodded in understanding as she sighed in defeat. "Maybe I should talk to my mom about what's going on. You think she will help Thals?"

"I mean it's better than nothing right? Who better to ask than the goddess of wisdom?" Thalia added.

Annabeth said nothing as she gazed into the ocean once again, clenching her fists tightly.

"I need to get stronger too Thals. I can't let Percy do all the work again if we find him at the Roman camp. I thought I lost Percy, but now that we know where he is I never want to lose him again. I don't want to lose any more people." Annabeth said her voice straining a bit.

Thalia in turn was surprised by her friend's resolve. She knew Annabeth was very strong albeit mentally, but she never expected Annabeth to make such a statement. Nonetheless, she grinned in response.

"So, you're going to start taking training more seriously Annie?"

"Yeah, I don't want to be some helpless girl like against Kronos. I want to be the one saving Percy this time instead of vice versa." Annabeth responded.

Thalia stood up extending her hand toward Annabeth which she gladly took. "Well becoming stronger probably means a good night's sleep, we can start training in the morning." Thalia said as she pulled her toward the cabins.

Annabeth smiled as she headed back, her mood considerably brightened and her goal much clearer now.

"Now all that's left is to talk to mom." Annabeth thought as she began to ponder questions she wants Athena to answer.

Camp Jupiter, Mess Hall Early Afternoon

"So probatio?" Percy asked to Dakota as they were eating lunch.

It had been a few days since Percy had become a member of the legion. The few war games that he participated in were fun like siege and gladiator which were held occasionally in the legion. Siege being one team defends a fortress and the opposing team attempts to attack and steal the opposing teams banners, while gladiator was a series of 1 on 1 fights. Percy fit in quite nicely into the legion ever since some legionaries heard about him beating the centurions of cohorts three, four, and five. He had garnered some respect, but there were still many things he did not know.

"Probatio, the lowest rank for a member of the legion. Usually it's given to either new members or to those that have not contributed anything worthwhile to the camp." Dakota responded.

"Hmm, anything worthwhile you say?"

"Yeah, like completing a quest or saving somebody's life." Hazel added, playing with her food.

"It's ok Perce, being a probatio isn't so bad you just have to clean the armory and do other various chores that nobody wants to do." Frank said sarcastically.

Percy laughed at that as he finished the last of his food before standing up.

"Gonna go train for a bit guys, I'll see you tonight for war games." Percy said as he waved goodbye.

"Don't hurt yourself Perce." Dakota said in response raising his kool-aid as Percy walked away.

Once Percy was out of eavesdropping distance he turned his head back toward Frank and Hazel.

"So what do you guys think of Percy so far?" Dakota inquired leaning back a bit.

Frank and Hazel blinked a bit before responding. "Why so curious Dakota? He's a member of our cohort after all." Hazel stated crossing her arms.

"No reason, but can you believe how he fights? I mean all of us were there right?" Dakota said looking back and forth between the both of them.

Frank nodded as he rubbed the back of his neck. "He's strong, extremely strong. He might even be stronger than Jason back when he was here."

"His words weren't arrogant, they were the truth. If he really did have water and maybe a bit of rest between those fights. He might have been able to beat Reyna." Hazel said in awe.

"I know, he treated his first three opponents like they were nothing. You think Sofia got lucky when he was fighting her?" Dakota questioned before getting bonked on the head by an elbow.

"Like nothing huh?" Gwen said as she sat down next to Hazel glaring at her fellow centurion as he rubbed his head.

"Ow, that hurt Gwen, jeez, your elbow, really?" Dakota whined.

"Why don't you try fighting him one on one, and see how well you do?" Gwen asked crossing her arms.

"And to answer your follow up question, I don't think Sofia got lucky. She just played it intelligently." Gwen stated, "The day I see that girl get lucky in a fight is the day I get stabbed by a pilum."

"How come she only talks to Reyna, Gwen?" Frank inquired.

"Dunno, to tell you the truth it's something I've asked other centurions about as well. But Reyna said it has something to do with her past." Gwen answered.

"Her past? You know Percy doesn't really talk about his past either huh? Like how he got so strong and where he learned how to fight and stuff." Frank pointed out.

"Well yeah, don't you remember him saying something about his memories and how there's this blank space in his head?" Hazel reminded.

"Right, almost forgot about that." Frank said sheepishly.

"Well whatever it is, hopefully he knows why soon, he is a member of the prophecy after all." Dakota stated.

With Percy

Percy was currently at the Field of Mars, practicing with his gladius. It was only a few days but he had been studying the Roman style of fighting that everybody here learned. It was based on team fighting, and using formations to your advantage along with various other tactics. But it's weakness was one on one fighting. Something that he was an expert at so he didn't need that much practice with it. However, the roman style did have its advantages it taught discipline and form. He took a few swings with his sword trying to combo his slashes with stabs, to make his attacks more quick and lethal. Suddenly the wind behind him began to pick up as he turned around shielding his eyes from the dirt that was blowing around.

It was Reyna who was riding her pegasus that appeared in the clearing that Percy was practicing in. She jumped off her pegasus flaring her cloak as she turned to address Percy.

"Mind if I join you for a spar?" Reyna asked putting one of her hands on her hips.

"Sure why not." Percy said.

Reyna unsheathed her spear on her back before it changed forms to a sword as she turned and faced Percy. "I've been rather rude to you as of late haven't I?"

Percy relaxed his stance before responding. "Yeah, just a bit."

They began trading blows nothing being said between the two of them for a few strikes.

"I was there on Circe's island that day." Reyna said as she took a step back.

"Circe's island?" Percy said slowly his eyebrows scrunching together.

Reyna nodded her head, "It was a long time ago, more than a year so it isn't surprising you don't remember."

Percy sighed shifting his feet. "It isn't that it was a long time ago, it's just that I really don't remember."

Reyna lowered her sword, scrunching her eyebrows at Percy's words. "What do you mean?"

"Honestly, before Minerva told me to go to the wolf house the rest of my memories have been just a blank space." Percy revealed.

"A blank space? You mean like amnesia?" Reyna prodded.

"Yeah something like that, I just hope everything comes back to me eventually." Percy said, "but you were saying about Circe's island?"

"It used to be my home before I joined the legion, I remember you being there along with a girl named Annabeth, and you guys were the reason me and my sister Hylla were forced to leave." Reyna said a bit angry.

"Oh that probably explains why you were hostile when I first came here." Percy said sheepishly.

Reyna shrugged before pointing her sword at Percy, "True, when you first came here I was angry, but after Juno's revelation I shouldn't hold such a grudge. I think you have enough on your plate now."

Percy readied his blade as he nodded at Reyna's words.

"You can say that again."

The pair traded blow for blow, neither side giving an inch until a voice was heard in the direction of the principia.

"Reyna! Reyna!" Leila yelled as she sprinted toward the pair.

"Centurion Leila, what happened?" Reyna asked, Leila having garnered her full attention.

"The principia with Octavian… I think it is better if you came to see it for yourself." Leila said as she started running toward the principia.

Percy looked at Reyna as she quickly whistled for Scipio to come as she followed Leila.

Percy glanced at Reyna's retreating form as he watched in envy. "Damn I wish I had a pegasus." he said, running toward the principia.

Linebreak

Percy arrived at the principia to a sight to behold. Paul the centurion of the 3rd cohort that he had defeated the other day was currently prone on the ground with Reyna's sword pointed at his neck. Nearby was Gwen, Dakota, Leila, and a few other centurions along with Frank and Hazel gazing at the downed body of Octavian with a spear through his chest.

And judging from the context of the situation Percy determined it was Paul who decided to kill Octavian, albeit for reasons unknown.

"I'll ask you once more, centurion," Reyna spat with disgust "Why did you do it?"

Paul grunted as Reyna's boot digged into his back forcing him closer to Gaia than he would initially like. Paul turned his head to the right to get his words out.

"The pretty boy felt justified to insult me. So, I did what I felt like he deserved. A disgrace like him as praetor? He could hardly best any Roman in a fight and he parades around Rome like some sort of god? I'd rather serve Terra than serve under him."

Percy tuned out the rest of Reyna's and Paul's argument in favor of confronting Frank and Hazel about the situation. A lot of what Paul was true, but still Octavian did not deserve to be killed in such a manner.

"Is he dead?" Percy asked, directing his question at Frank and Hazel who turned their heads toward him.

"Yeah, dead as a doornail." Leila replied standing up after retaking Octavian's pulse.

Dakota whistled as he observed where Paul's pilum pierced Octavian's body.

"One thrust right through the heart." Dakota whispered clutching his own chest subconsciously.

"He was dead before he even hit the floor." Sofia said offhandedly leaning against one of the principia's stony columns.

"It's weird though," Hazel began from behind Frank her eyebrows were scrunched up and her eyelids closed in concentration.

"What, too gruesome for you?" Leila said cringing as she noticed the amount of blood on Octavian's purple shirt and the pool of blood growing around him.

"No, it's just I can't sense that he died." Hazel said confused.

"What do you mean Hazel?" Frank asked also vexed.

"As a daughter of Pluto, it's one of my abilities to sense whether something or in this case someone has died, but when I focus on Octavian's body I sense nothing. Unless…" Hazel said her eyes widening as she pointed at Octavian.

It looked like something straight out of a zombie movie. Everybody stood still staring wide eyed as Octavian slowly stood up pulling the spear out of his chest with a sickening squelch. It looked as if it didn't even cause him the slightest amount of pain. His eyes glowed golden vastly different from its usual blue as he stared directly at Percy.

When he spoke, his voice sounded the same but tripled, quadrupled even as if multiple Octavian's were speaking at once:

"Son of the seas do not fear the sky,

Through him you will gain an old ally,

War, Wisdom, and Wealth will face death,

A truth be revealed that one will confess."

After his last words he collapsed back down again, laying spread eagled but his eyes open slightly.

"Am I dead?" Octavian rasped out taking deep breaths to slow his heart rate.

"Impossible! Your heart was ruptured and you had no pulse! How in the world are you alive?" Leila yelled in astonishment.

"I think I can answer that question." a voice said after a brief flash of light.

Mars appeared in the principia in army garbs with a rifle slugged onto his back and also wearing a grim look on his face.

"What you just heard right now, is the result of Thanatos being captured."

"Lord Mars." echoed the voices of the present members of the legion as they bowed slightly to acknowledge the god of War.

"Thanatos the god of death?" Percy asked, the only demigod not bowing.

Mars narrowed his eyes at Percy's lack of respect. "You would do well to respect me boy, there is a field named after me in Rome after all."

"But yes, death has been captured by none other than Terra herself, and because of this the doors of death have been opened due to Terra's influence." Mars stated.

"This is also the reason your augur over their lives even after suffering such a lethal wound. Terra's army will never diminish as long as the doors of death remain open but the same is true of ours."

"Would that not satisfy your desires though? As the god of War, you must benefit from Terra's army not dying along with us demigods not dying as well. It would be a constant state of war until we close the doors." Percy said crossing his arms.

Mars hefted his rifle from his back to his front, not pointing it at Percy, but the reasoning behind his action was obvious.

"You should watch your words son of Neptune. I may be the god of War but I am also the god of Rome, the legion is my priority and I will not fight useless wars with no reasoning. I have no ill will toward your father and I certainly don't want a reason to bear any toward you. However, keep up your rudeness, and even the doors of death will not be able to resurrect you." Mars said warningly.

Before Percy could continue Reyna stepped forward, "You were saying Lord Mars about Thanatos?"

"Ah yes as I was saying. The Gods believe Thanatos to be trapped somewhere far North where we have no influence and no control, somewhere outside the United States. The quest members have already been determined within Octavian's prophecy, but I will say that my son must go on the quest as well."

"Are you talking about Paul, Lord Mars?" Hazel asked.

"That blood traitor?" Mars spat as he glared at his son who was still on the floor.

"His fate has already been decided, and I trust our praetor will make sound judgement along with the Senate. No, my son Frank must go." Mars declared.

"Me? But why father?" Frank asked befuddled.

"No son of mine, will be such a weak demigod. Now is the time to prove your worth to me, and to prove your worth to Rome." Mars proclaimed.

"Since the Olympians, seemed to know the prophecy was coming. Do you have an answer for why Octavian was able to reveal one without his dolls or the temple of Jupiter? He is only a legacy of Apollo after all." Sofia stated.

Mars turned his eyes toward the girl and smirked. "You are smart girl, not many demigods would have caught that small fact. You might even be a little too smart."

Sofia said nothing as she waited for Mars to answer her question.

"Apollo had a similar question when we were discussing it on Olympus. Not all the Gods were present so it is something we must discuss later at a different time. But he theorizes that because Octavian "died" but did not cross the doors of death was why he was able to spout such a prophecy. Even us gods can't tell the future, we can only predict what will happen. Even Apollo himself the god of Prophecies, cannot decipher every line with perfect accuracy. There is always something that changes." Mars replied.

Lady Lupa then appeared exiting the principia in her human form. "Will that be all Lord Mars?" she said as if listening to everything.

Mars nodded and flashed away.

"Quite a predicament we have been placed into. A few days after Lady Juno reveals the Prophecy of the Seven is being set in motion and we have another prophecy to deal with along with the doors of death." Lupa muttered.

"Praetor Reyna do you feel you have the members of the quest figured out?" Lupa asked suddenly facing Reyna.

Reyna nodded her head as if expecting Lupa to ask her such a question.

"Usually in an event such as this I would consult the senate, especially about going somewhere out of the gods realm. But since Mars has witnessed the prophecy himself I will just consult the centurions who are all here." Reyna said looking at Lupa for permission.

Lupa just looked at Reyna motioning with her hand to go on.

"The prophecy itself is most likely in response to Octavian "dying" which in turn revealed the doors to be open which is for us to close. "Son of the seas do not fear the sky" the first line is simple as there is only one son of the seas currently in the Legion." Reyna deduced turning her eyes toward Percy.

"Do not fear the sky…" Percy said to himself wondering what it could mean.

"The second line, "Through him you will gain an old ally", clearly it references the "sky" in the first line so this line is much harder to deduce until we know who the "sky" is."

"You think it has something to do with Jason?" Frank asked.

Reyna flinched a bit at Jason's name before regaining her composure and nodded her head at Frank's question.

"That is my suspicion. Next, the third line reveals the rest of the members of the quest. War, Wisdom, and Wealth will face death, clearly it speaks of Frank son of Mars, which has been confirmed due to Mars stating you will go on the quest, Sofia daughter of Minerva who is also the goddess of Wisdom,"

Out of the corner of Percy's eyes he saw Sofia's reaction as she shifted her feet. Her face was stony as she realized this quest may be incredibly dangerous.

"And finally, Hazel daughter of Pluto which will complete the 4 members of the quest. Frank, Hazel, Sofia, and Percy." Reyna concluded.

"The last line though is a mystery to me. A truth be revealed that one will confess. Right now, it's too early to tell what it means." Reyna confessed.

"Maybe confess has something to do with how Paul killed Octavian? You know something to do with treason?" Dakota inquired.

"No, the problem with that reasoning is that the event happened before the prophecy was revealed and even then, it doesn't seem like that would match up." Reyna replied.

"Sofia any ideas?"

All eyes turned to Sofia as she ignored everybody's stares and responded to Reyna.

"Could be a traitor revealing themselves later." she said sharply.

Everybody present was surprised at her accusation.

"Are you kidding? Somebody actually betraying the legion?" a legionnaire shouted out.

If Sofia was surprised at the response she didn't show it as she began walking away to get her things ready. "You saw it with Paul, treason isn't something that is out of the realm of possibility anymore."

"Centurions any objections to the members being selected?" Reyna asked already knowing the answer. Nobody had a question which led to Reyna dismissing everybody except Percy, Frank, Hazel, Lupa, and Paul.

"Lady Lupa, I will let you handle Paul here as I debrief these three about the quest."

Lupa nodded as she picked up the unconscious Paul and Octavian as she made her way back to inside the principia.

"What's going to happen to him?" Percy questioned.

Reyna raised an eyebrow at such an obvious answer. "He committed treason, and the punishment for treason is death. However, since the doors of death are open he will have to be locked up for now."

"Shouldn't Sofia be here as well? She's a part of the quest as much as any of us." Percy stated.

"Don't worry too much about her I'll brief her in the morning, she's also going to be the leader since she has the most years in the legion and is centurion." Reyna answered. "I'll also say a few more things to her concerning you three."

"You will be leaving tomorrow so prepare yourself. The doors of death need to be closed or this effort against Terra will be all for naught."

Percy glanced at Frank and Hazel each of them knowing this was a serious matter and that a mistake could mean not just death for them but death for the world as well.

"Far north right? Would that mean somewhere like Canada?" Percy asked.

"That's what I initially thought, but it seems like it would be somewhere like Alaska. It's where the golden eagle was lost as well." Reyna said.

"Golden eagle?" Percy said vexed.

"Frank and Hazel will explain it to you, right now I have to talk to Lupa about the quest before you leave, I'll see you off in the morning." Reyna said as she walked into the principia.

The trio of demigods began walking back to the fifth cohort's barracks nobody saying anything for a minute as Percy reiterated his question to Frank and Hazel.

"The eagle used to be the pride of the legion, Percy. It was said to be given to us by Lord Jupiter himself and blessed with his power. Julius Caesar nicknamed the twelfth legion "Fulminata" because of its destructive power with lightning." Frank stated.

"It's also the reason the fifth is known as the laughing stock of the legion because we caused such a blunder. Well not we it was by Michael Varus a member of the legion from the 1980's who tried to fulfill the prophecy of the seven but a majority of the fifth cohort, himself included was killed." Hazel added.

"Wow, ironic isn't it that I'm a member of the prophecy of the seven then right?" Percy said.

"Kind've but the eagle isn't our priority it's freeing Thanatos first." Hazel said before glaring at Percy.

"You know Mars is the second most respected god in Rome right? Do you have something against him or the gods in general to act like that?" Hazel asked incredulously.

Percy shrugged in response to her question. "I don't know it's just something with Mars that I don't like. Maybe it has something to do with my past."

"I'm sure this quest will reveal some answers about everything Percy, especially concerning your memories." Frank assured.

"Yeah I hope they do."

Olympus

On Olympus, a certain sea god was not happy after watching a new prophecy be revealed in Rome and also watching his lost son become the center of it didn't do well to douse his anger.

Ares growled as he was launched backwards landing on the floor roughly, Poseidon's eyes glaring at him as he readied his trident for another attack.

"Why is my son at the roman camp Ares? And why oh why IS HE THE CENTER OF YET ANOTHER PROPHECY?" Poseidon yelled as he threw his trident at Ares, narrowly missing his head.

Ares stood up, glowing slightly shifting into his Roman aspect. "I had nothing to do with the outcome of this Poseidon, I was merely a messenger since I am Rome's god."

Poseidon calmed down a bit at this, knowing Ares' roman aspect to be more truthful and more in control than his Greek one. "So who then Mars? Who is responsible for this?"

"That would be me." Athena said flashing into the room with Hera by her side.

"Athena? You are responsible for this treachery? Did Percy not suffer enough when he had to face Kronos? And now you're telling me he is a member of the seven?" Poseidon asked animatedly.

"I won't lie to you Poseidon, it was our doing. To take away Percy's and Jason's memories along with swapping them at their respective camps to unite the Greeks and Romans eventually." Hera confessed.

"However." Hera started glancing at Athena, "Athena decided to take some matters into her own hands."

"Such as?" Poseidon said growing impatient.

"I decided to take away Percy's memories completely, unlike Hera who restored Jason's memory after his quest was completed. My reasoning being that once he finds out about his friends at the Greek camp, he wouldn't become the leader that I envisioned. His fatal flaw is personal loyalty after all." Athena stated calmly.

If Poseidon could grow any angrier than he did at Ares he certainly kept it hidden as he shifted into his roman form Neptune.

"You would do well to not do any more meddling goddess of wisdom." Neptune said glaring at Athena. "But if it is to make my son successful in his quest and to eventually be rid of this upcoming threat, I will leave it alone."

Neptune said nothing more as he flashed away leaving Athena, Hera, and Mars.

"That went a lot better than I expected it too." Hera said a ghost of a smile on her face.

"Maybe for you too, you didn't get thrown onto the floor." Mars said gruffly flexing his shoulder.

"It is no surprise that Poseidon would be this angry. I actually expected him to be much angrier." Athena said turning toward Hera. "And to sell me out in front of him? Do you have no shame mother?"

Hera shrugged at her response. "I hope you know what you are doing daughter, I have no control over what Perseus does anymore. Turns out I can't even tamper with his memories anymore. Let's hope whatever you're planning has some merit to it."

"His quest is just beginning, but even I did not expect a prophecy to reveal itself. If anything, he will overcome this and become stronger than he already is." Athena declared.

"He certainly didn't forget about disrespecting me when I met him that's for sure." Mars added.

"Even for as much as his memories get changed, I can't change his emotions. He probably remembers how he felt when fighting you when father lost his master bolt a few years ago." Athena said.

"It explains his attitude towards me, but he needs to learn respect. Insubordination is not the Roman way it's too Greek."

Athena then shifted into her Roman form pondering about the upcoming quest.

"I agree. He hasn't disobeyed orders yet, but he is still Greek in his roots. I have faith in my daughter to lead the quest. Let's just hope Perseus listens to what she has to say." Minerva stated.

"I know Sofia is smart enough to lead them. I just hope she doesn't remain too cold toward the other three. It's important for her to open up." Minerva thought to herself.
