Hey everyone, I've had this idea of doing a survival/post-apocalyptic PJO story for a while and have finally decided to put some words on paper for it. This was inspired after I watched 'The Last Ship,' which yall should watch. I don't wanna say anything else other than if you enjoy what you read, feel free to check out my other stories or support me in the land of Patrons or on Twitter.

It's all under the same name 'Neptunerover'. With your support, I can spend more time writing and updating the stories you like to read! A link to my Pa treon is in my Twitter bio for anyone who wants to support me.

I do not own Percy Jackson and the Olympians. If I did, I'd have an Audi R8.

Captain Percy Jackson of the USS Trident let out a sigh as he stared out the bridge, watching the ebb and flow of the waves. He and his crew of two hundred and thirty-seven sailors had been on a top-secret mission from the Secretary of Defense himself.

It had required a long and arduous six months of radio silence where neither he nor anyone else on board the ship had been able to contact home or their loved ones. It didn't bother Percy too much, but he did feel for his crew.

Unlike him, they had family and loved ones waiting for them. All he had left was his little sister Estelle, who was living her own life in Virginia. They still talked, but after their mom died in a car accident with his stepfather Paul, they had drifted apart.

It was his fault; he knew it. Once the only parents he had ever known died, he had immediately enlisted in the US Navy, throwing himself into the regime as a way to deal with the tragedy instead of fully being there for his sister.

There was probably some sick and twisted form of irony in that decision, considering his birth father had been lost at sea from what his mother told him. But he chose to not focus on that. He had joined the Navy for two reasons.

The first was because he had always been drawn to the sea, even before he found out that was how his father had perished. The second was because the Navy was willing to provide housing for himself and Estelle.

The wives of the other service members practically raised his sister while he went through basic training and officer's school before he finally realized that he had failed to be there for her.

By then, it was too little too late, and while she didn't resent him. She wasn't exactly his biggest fan either, which broke his heart. Nonetheless, he still made sure all her wants and needs were taken care of.

He put practically ninety percent of his substantial salary as a captain in the US Navy in a trust that he had told her their parents had. It was a bit of a white lie, but he knew if he told her it was his money, she would never take it.

While it would never make up for him abandoning her when she needed him most, he would be damned if he ever left her alone again. Realization dawned on him as he understood how he had developed his fierce sense of loyalty for the first time.

The sound of a bosun's whistle broke the man out of his thoughts as he remembered why he was on the bridge. His Executive Officer, a burly man by the name of Frank Zhang, grinned and clapped his hands.

"It's officially o'800 on the twenty-third of April, Captain. Ready for the final test?"

Percy grinned as he rested his hand on the phone on the bridge.

"More than ever, XO Zhang."

Picking up the phone, he called his Tactical Action Officer.

"TAO, bridge."

"Bridge, TAO"

"Our helo has just dropped our final target. It's five feet long, two feet wide, and has no heat signature. Let's get hunting."

"TAO confirms, target is five feet long, two feet wide, and has no heat signature. Beginning search."

Hanging up the phone, he felt the ship begin to move as they cut through the freezing water like butter. His Tactical Action Officer was a woman named Piper McLean, and she had been an outstanding sailor during their mission so far.

As the USS Trident sliced through the water, no doubt towards their target, Percy took a moment to enjoy the calm as they went through the final weapons test before they could lift their radio silence.

While their ability to head home would depend on their resident virologists, Annabeth Chase and Luke Castellan, completing their project. His crew would be able to at least talk with their loved ones.

The Arleigh Burke-class destroyer was one of the latest and greatest of the Flight III program, and that meant they were the lucky ones chosen to test some of the newest weapons the United States had to offer and chauffeur some scientists to the South Pole, so they could study some birds.

At least, that was what the Secretary of Defense told him, and he had learned not to question his superiors. The sound of a missile being launched caused Percy to look up at the screen above his chair as it started to beep while he watched the missile move toward its target.

The tone intensified as the missile got closer before silence as the words 'DETONATION' flashed across the monitor. The speakers on the bridge crackled to life as Piper's voice came through.

"Boom, confirmed target detonation."

Percy grinned at the woman's enthusiasm as he stood from his chair before grabbing the bridge's phone once more.

"Good morning Trident, this is the captain. After six months at what XO Zhang likes to call the worst Baskin-Robins on the planet, we have just passed our final test, and I'm proud to say you did it with flying colors. I will call the Pentagon today to confirm that we can break EMCON. Enjoy your success."

Cheers broke out around him on the bridge, as he imagined they did everywhere else on the ship. After all, they all knew just as much as he did that radioing command to confirm they could break radio silence was a formality more than anything else.

As the people around him celebrated, he took a closer look at the monitor that showed a little over a dozen dots on the continent itself. Two of them belonged to his virologists, one the leader of his Mountain Warfare unit, Jason Grace, and the rest to Jason's team.

"XO Zhang, you think the good doctor has gotten everything she needs?"

The Executive Officer let out a chuckle.

"I don't know, sir. But, I'm sure Grace and his men sure hope she has. Those poor sailors don't get any reprieve from the wind."

Percy nodded his head with his own chuckle.

"I'll second that; I'm going to go call the Pentagon. Check in with Lieutenant Grace and see how everything's going over there. Now that we are done with our primary mission, I'd like to head home and give our sailors some well-deserved R&R."

Frank gave him a cheeky smile as he saluted him.

"Aye, Aye, Captain."

Percy sighed as the rest of the bridge saluted him, following the Executive Officer's lead. He was going to get Zhang back for that. The man knows how much he hates that little rule of the Navy. Just because he was the Commanding Officer didn't mean he deserved any more respect than the rest of the men and women on board his ship who put their lives on the line.

Waving off the signs of authority, he made his way toward the Communications Room. There, he would open up a secure channel with the Department of Defense and, hopefully, get some good news about lifting the radio silence.

XX

Annabeth Chase took a second to take a drink of water before getting back to digging through the permafrost. She desperately hoped they'd find the original strain of the damn virus this go around.

When she had talked with the President about this mission, she had tried to get him to lift the radio silence mandate to no avail. Both he and the Secretary of Defense had been adamant about keeping a communications blackout for their assignment, herself included.

Even the captain of the ship she would be hitching a ride with didn't know the actual cause behind their trip to the bottom of the world. The only ones who knew the truth were the people in that meeting, which were herself, the President, the Secretary of Defense, the Head of the CDC, and Luke.

Their reasoning was simple: if the K-virus continued its rapid spread and the ship's crew found out their family was in danger, they would likely have a mutiny on their hands. Granted, she didn't disagree with their reasoning. She just wished there was a way she could've avoided the communications clampdown.

Not because she wanted it for her own personal reasons. No, she wanted to be able to talk with her fellow scientists and colleagues to stay up to date about any mutations or the latest infection numbers from the virus.

She didn't have any family to worry about, growing up an orphan in California after her father died when she was seven. Her stepmother had dropped her off at a foster home named Camp Half-Blood because she didn't want to care for a child that wasn't hers.

Her birth mother was out of the question, having died during childbirth. The only two people she cared about in her life were Chiron, who ran the foster home she was dropped off at, and her friend Luke, who was like the brother she never had.

Shaking her head to focus on the present, she grabbed another sample of bird feces before running it through her scanner for the primordial strain of the K-virus. As the machine processed the excrement, she looked out over the vast plain of white.

Antarctica was beautiful in a weird way, and if the fate of the world didn't rest on her shoulders, she might've been able to appreciate it. Things hadn't been looking good when they left. While the virus hadn't garnered national or global attention yet, it was on the fast track to.

From the little data she could gather before raising it up the flag pole, the disease would kill its victims within twenty-four to forty-eight hours. However, that wasn't the scary part. Plenty of things were faster acting and more adept at killing humans quickly.

The terrifying part was that it seemed to be highly contagious. While it wasn't airborne from what she knew before heading to Antarctica, it spread through the tiniest instances of contact. Even the smallest amount of someone's spittle landing on exposed skin would be enough to infect another person.

That's not even taking into account that the virus seemed to attach itself to the nervous system. Her worst fear was that it mutated to either be airborne or could find a way to take away people's motor function, similar to Polio.

The beeping of her scanner broke her out of her thoughts, and she nearly dropped the device in shock. It was a match. Carefully, oh so carefully, she dug up the rest of the feces she found before putting it in her cooler, along with her sample.

However, before she could continue to search the area for more instances of the primordial strain, the sound of a helicopter in the distance filled her ears. Pulling out the radio on her belt, she contacted their chaperone.

"Jason, I just made a breakthrough and need at least another two hours. Can you have the helicopter come back by then?"

She put the speaker up to her ear to hear the man's reply but frowned when all she heard was a garbled mess of static. Moving the radio away from her ear, she checked to ensure she was on the right frequency before realizing her mistake.

Nearly slapping her forehead in stupidity, she released her thumb from the talk button as the static cleared, and Jason's voice immediately came through the speakers.

"Helicopter? Doctor, the helicopter is back on the Trident. Are you feeling all right?"

Tilting her head in confusion, she focused on the sound she heard in the distance, only to come to the same conclusion. Normally, she would've played along with the man's teasing, happy to no longer be an outcast amongst the crew.

However, her discovery didn't have her in a joking mood. Her reminiscing had reminded her how important the mission was, and now that she had finally found what she was looking for, she didn't feel like playing along.

"I'm serious, Jason. We've been here for six months. Do you not think I know how to distinguish the sounds of a helicopter from the wind. Now, I need at least another two hours, but if you can spare some manpower, I can make it quicker."

There was nothing but static for several moments as she heard the Helicopter blades get closer and closer. Finally, Jason's voice came across the speakers.

"Don't move, Doctor Chase. We are coming to you."

She didn't quite expect the Lieutenant himself to come help her, but she wasn't going to complain. Returning back to her work, only to look up in frustration as she heard the helicopter closer than ever.

Her look of frustration quickly turned to one of surprise and then horror as she saw three helicopters come from behind the mountain from their right. None of which looked like the one that had ferried her and Luke to and from the ice during their stay.

"Luke! The samples... We've got to get the samples!"

Her partner looked at her like she was insane.

"Forget the samples! We've got to get out of here!"

Something sounding akin to a bottle rocket being let off on the fourth of July reverberated behind her. In an instant, something struck one of the helicopters faster than the eye could see, leaving behind a trail of white smoke.

There was an explosion as she watched the stuck helicopter immediately fall from the sky in a ball of fire. Just as Jason's voice screamed behind her.

"MOVE! WE ARE LEAVING!"

Her right ear was still ringing, no doubt from the missile that streaked past her, as she turned her head to the Lieutenant. Seeing him wave her towards him as Luke got on the back of the snowmobile that held one of the other soldiers.

Turning back, she saw the case that had all her samples of the primordial strain sealed, lying a dozen feet away from her. She sprinted towards the case, picking it up before turning and racing towards the Lieutenant's snowmobile.

She wasn't sure when the other soldiers showed up, but all of them were shooting their rifles at the remaining helicopters. Her legs burned, and her lungs were on fire from the cold air she was breathing in as she sprinted through a couple feet of snow toward her salvation.

A spray of bullets impacting the ground in front of her caused her to stop as one of the helicopters circled around. Two men jumped from the helo and into the snow, only to be shot before they could even fully stand up.

Then another spray of bullets into the helicopter blocking her path hit the tail rotor, causing it to spin uncontrollably towards four of the soldiers protecting her. She heard Jason curse as the crashing helicopter hit two of the men.

Pieces of shrapnel went flying, one of which flew past her right side, barely missing her as another hit one of the soldiers who managed to escape the initial crash. She didn't know how or when she fell, but she picked herself up from the snow just in time to see another streak of white smoke as the remaining helicopter fell from the sky without any flames.

It was as if a puppet's strings had been cut. One second, it was flying, and the next, it was falling. The sound of gunfire died down, but she still ran the rest of the way to the snowmobile as Jason barked out orders to the rest of the men.

Three broke away from the group to go check on the four who were in the proximity of the crashed helicopter while the rest set up a perimeter around herself and Luke. Jason marched over to her, his face contorted in rage and anguish.

"I hope whatever is in that case was worth the lives of my men, Doctor Chase."

She opened her mouth to respond but stopped, realizing it was a rhetorical question. She was about to ask what in the world happened when one of the soldiers in their perimeter fell over, dead.

Less than a second later, she heard the sound of the rifle that had killed the man just as Jason shouted out a new set of orders.

"SNIPER, GET TO COVER!"

The next thing Annabeth knew, she was being thrown behind one of the snowmobiles, doing her best not to land on the case as another round of gunfire started around her. Pushing her back to the snowmobile, she hugged the case close to her body, both as a way to protect it and anchor herself in the chaos happening around her.

She hadn't really valued the protection detail that was assigned to her while on the continent, mostly because she didn't think they were needed and would only get in her way. Now, though, she couldn't have been more thankful as she watched them in action, operating like a well-oiled machine.

There was a cacophony of noise as the soldiers yelled to be heard of their own gunfire and that of their enemies. She didn't recognize most of the voices but was content to listen in an effort to keep calm.

"Two tangos, six o'clock."

"Sniper, down."

"I got three more targets at our twelve."

"I'm Winchester."

"Extra magazine in my back left pouch. Grab it, Valdez."

"Another four tangos just showed up at our three. We're going to be surrounded if we wait much longer."

"Sure could use some help from the Trident right about now."

"Focus, if they could assist, they would be. Pick your shots and conserve ammo. We don't know how many more could be coming. Focus fire on our twelve; we need to clear a path that we can use to escape with the jet skis. Protector the Doctor's at all costs."

Jason's voice was reassuring over the sound of gunfire all around them, and Annabeth vowed to apologize and thank the Lieutenant once they got out of this mess. She also decided that she would tell the ship's captain the truth behind her mission and, ultimately, theirs.

She was willing to bet her whole bank account that this attack was related to the K-virus, which meant that things must have gotten dire back in civilization for someone to think it was a good idea to attack a US Naval Warship.

After another ten minutes of gunfire, she could hear the sound of helicopter blades whirling in the distance. For a second, she feared it was reinforcements for the enemy, a fear she assumed Jason shared with her judging by his commands.

"College, ready our last missile. If that isn't our helo, I want it shot out of the sky before it knows what hit it."

A man with glasses, next to one of the other snowmobiles, shrugged a tube onto his shoulder. Something Annabeth quickly realized was a rocket launcher as he aimed in the direction they heard the helicopter blades from.

"Clear backblast!"

One of the soldiers beside this 'College' moved up and beside him as he shouted out in response, continuing to fire his weapon as he did so.

"Backblast clear!"

Annabeth waited with bated breath, sighing out in relief as she recognized the helicopter that appeared from behind the mountain. Cheers sounded off around her as their helo cleaned up the remaining soldiers around them from above.

Once the last enemy fell to the stream of bullets from the minigun on their helicopter, she saw Jason put the radio to his mouth, a small smile on his face as he did so.

"Boy, am I glad to see you, Thunderhead. I have at least one K.I.A. and one critically wounded from my last sit-rep. Are you able to land close?"

The Lieutenant pulled the radio away from his mouth as a female voice burst through the speakers of his radio.

"Copy that, Sparky. I should be able to set her down about fifty feet to your West. Sorry we're late to the party. The Trident was attacked at the same time, and we were grounded. I know the Captain wants to speak with you and Doctor Chase ASAP."

"Roger that, if there's room, I'll tag along and leave Valdez in charge."

With that, Jason attached the radio back to his belt as he shouted over to the man in question.

"Leo, give me a sit-rep. Thalia is landing fifty feet to our West in the next three minutes."

"Fletcher and Yew are K.I.A. Green was impaled by some shrapnel and is currently unconscious. The rest of us just have minor injuries, although Beckendorf has a broken collar bone and maybe more."

From what Annabeth could tell, he took the information in stride. No doubt the result of years of experience and training kicking in as he issued his orders.

"Alright, the CO wants Doctor Chase and me back on the ship ASAP to debrief. So, I'll be joining her, Castellean, Green, and Beckendorf on the ride home. Valdez, you're in charge in my absence. See what you can figure out about our attackers. I thought I saw the Soviet Star on one of those helo, but I'm not sure."

With that, the Lieutenant motioned for her to follow him as she caught a glimpse of Luke for the first time since the attack. He looked white as a sheet; she couldn't blame him since she imagined she looked the same.

Two soldiers carried a man with a piece of metal sticking through his leg, and Annabeth lost her lunch. The only thing keeping her sane at the moment was the case held securely in her hands, and after cleaning herself up, she made her way into the helicopter, sitting down in one of the empty seats.

She tightened her grip on the case as they took off, her mind wandering to the two soldiers who died and the one who looked on the brink of death lying on a stretcher between the two rows of seats.

At that moment, she decided that she wouldn't stop until she had successfully created a vaccine.

Percy Jackson had just sat down in the Communications Room when all hell broke loose. The first thing he noticed was the General Quarters Alarm, quickly followed by Master Chief Petty Officer Underwood's voice over the ship-wide intercom.

"General Quarters, General Quarters, all hands man your battle stations."

His instincts and training took over as he sprinted out of the Communications Room and into the Combat Information Center. He looked over to McClean, who immediately gave him a sitrep.

"Captain, we picked up three... Make that six unknown aircraft approaching from the East."

Percy glanced at the screen as he watched six red dots appear on their radar, three of which seemed to break off from the pack. Realization dawned on him as he picked up the phone in the CIC.

"Bridge, this is the Captain."

"Captain, this is the Bridge. What are your orders, sir?"

"Warn Grace and his men they have three unidentified aircraft inbound to their position."

"Bridge confirms, sir."

Setting the phone down, he looked back at McClean's screen as he overheard one of his other sailors attempting to communicate with the aircraft.

"Unidentified Aircraft, please identify yourself. This is the USS Trident of the Pacific Fleet. If you do not comply, you will be fired upon."

If there was a response, Percy didn't hear it over the explosion of a missile hitting some part of the ship, causing it to rock back and forth violently. Then, a second explosion hit before he could even get a word out.

Thankfully, his sailor's training kicked in, and they were already bringing the Trident's ample amount of firepower online. Not needing an order from him now that they had been fired upon. Still, he couldn't help himself as he gave it anyway. No one got to mess with his ship and live to tell the tale.

"TAO, let's blow these pests out of the sky and show them why you don't mess with the United States Navy."

Piper McClean grinned as she and the rest of the crew sounded off their 'affirmatives' as their weapon systems finished getting online. Percy heard the Sea Whizz whirl up and let loose a barrage of bullets at four-thousand five-hundred rounds per minute.

He heard the missile explode, and the ship rocked slightly, but it was nowhere near as bad as the first time. Telling him that the gun had done its job. He heard it spin up again, and this time, he heard one of the sailors shout out in victory.

"One bogey down, two more still circling."

He heard their chaff decoy launchers activate and felt another explosion rock the Destroyer slightly. At the same time, he heard a set of Sea Sparrow missiles launch and an audible explosion that was nowhere near the ship.

"Two bogeys down. The last one is still circling."

Percy felt himself grinning as he gave his first command since they'd been fired upon. Eager to use the weapon that the Arleigh-Burkes were known for.

"Bring up the 5-inch."

"Aye, sir. 5-inch coming online."

"Target bearing 2-7-0 degrees. Cleared Hot."

This time, the ship moved as the Mark 45 Gun fired. Piper pumped her first, letting Percy know they had gotten their target. Her words a second later only confirmed it as he put his hand on the Comabt Information Center's phone again.

"All three unidentified aircraft have been grounded, sir."

"Great job everyone. TAO, start working up a strike package to assist Grace and his men while I contact the Bridge."

"Aye, Aye, sir!"

As they worked, he picked up the phone and dialed in the bridge.

"Bridge, this is the Captain. All bogeys have had their wings clipped. Check-in with Grace's team and let them know we are ready to support them. Have our helo pick them up, and let Doctor Chase and Lieutenant Grace know they are wanted back for debriefing yesterday."

"Aye, sir!"

He set the phone down and took a deep breath to control his rage. They were at EMCOM Alpha. Their attackers shouldn't have been able to triangulate their position. The only explanation he could think of was that someone had broken their radio silence, and only two people on his boat weren't a part of the US Navy.

Putting that anger to the back of his mind, he focused on the present as the Combat Information Center buzzed with chatter. From what he could gather, there were no casualties on the ship, and the damage from the missiles that made contact was minimal.

The phone to his right rang, and he instinctively picked it up.

"This is the Captain."

"Sir, it's the Bridge. We are unable to contact anyone on the continent. Thalia is already airborne and en route. What would you have us do?"

A hundred different scenarios flashed through his mind with the new information. But he took a breath to calm himself. Jason was one of the best. If the team wasn't communicating, then it was because they couldn't afford to.

"They could be in a firefight. I want you to try again in three-minute intervals. Let Thalia know I want Lieutenant Grace and Doctor Chase back for a debrief ASAP. Also, see if we can identify who attacked us. I want to know who we just went to war with."

"Aye, sir!"

Putting the phone back in the receiver, he let out a long sigh as he watched the radar and sonar, on the lookout for any more activity. But, if their enemy was a foreign military, he doubted they would attack again soon unless it was a full-on fleet.

However, if that was the case, he would've expected their initial attack to have been a much larger force. Either way, they had successfully defended against their first attack and were on high alert for another, which was why he doubted they would attack again so soon.

Anyone with military experience could tell you that now was the worst time to launch a counterattack. The USS Trident was more than ready, and no time would be wasted trying to communicate with the enemy this go-around.

Taking another breath to calm himself and keep a level head, he exited the CIC and went towards the helipad to wait for Lieutenant Grace and Doctor Chase. He wanted answers, and by god, he was going to get them.

XX

Jason Grace clenched and unclenched his fist as the helicopter approached the USS Trident. Two of his men were dead in the ambush, and Green was holding on for dear life. Yew's wife was supposed to have given birth to their first child two months ago.

However, due to them being in EMCON, they didn't have any information. Now, when he next sees Amber, he'll have to tell her that her husband is dead, and their child will be growing up with a father.

It was something he had personal experience with, and he hated that he couldn't have saved him. No child deserved to grow up like he did, fatherless. Taking a breath to calm himself, he focused on putting on a brave face.

His men needed him to be strong right now. They had just lost two of their brothers and might lose a third if Solace couldn't save Green. He had faith in the ship medic. In fact, Will Solace was the best medic Jason had ever seen, but his friend's wound didn't look good. He didn't know if they had everything they needed on the ship to save him.

Thalia's voice cut across his headset, causing the Lieutenant to sit up just a bit straighter as her words registered in his brain.

"Touchdown in 3... 2... 1... Clear to disembark. Good luck, and be sure to rate your Uber for a chance to win a free in-flight meal next time you fly."

Jason chuckled at the woman's antics as he disembarked once two other sailors grabbed Green's stretcher and pulled him out of the helicopter. Will immediately started looking over and assessing his teammate's condition as they disappeared into the ship's depths towards the medical bay.

Another sailor helped Beckendorf out of the Helicopter and put his arm in a sling before helping him toward the medical bay as well. He spotted the Captain off to the side before motioning to the two doctors to follow him as he made his way to the CO.

Once they were clear of the helicopter, he felt the wind at his back as Thalia took off once again to pick up the rest of his team, along with any intel they could find. He had a sinking feeling it was the Russians who attacked them but hoped that it was some faction that went rogue.

The idea that he and his team could be one of the causes of World War Three terrified him. The Captain's voice broke him out of his thoughts as he gripped the man's hand in a warrior's handshake.

"Lieutenant Grace, I'm sorry to hear about Yew and Fletcher. Doctor Solace will do everything he can to save Green, but we need to focus on what happened and our next steps. You three follow me."

Jason nodded in thanks to the Captain, to which the man returned as he paused to let the two Doctors ahead of him so that way he could bring up the rear. He was no fool and knew the Captain wasn't either.

If everyone on the ship was following EMCON Alpha, then their attackers would've never known their positions to initiate an attack. Only two people on the ship weren't US Navy, and thus the most likely breach.

The group arrived at the ship's secure communications room, and the first words out of the Captain's mouth immediately told him what type of mood he was in.

"Everybody out, NOW!"

All the sailors hustled to exit the room, and once they had done so, the ship's Commanding Officer shut the door. Jason found himself involuntarily tensing up as Percy Jackson's gaze swept over them.

While he had known the Captain for several years and had even gone on dozens of combat missions with the man, he was still intimidating. He locked eyes with Percy and knew what was coming before the man even spoke.

"Lieutenant Grace, give me a sit-rep on what happened."

Just as he opened up his mouth to give his report, Doctor Chase attempted to speak, causing him to bite his tongue as Percy went off on her.

"Sir, bef-"

"I asked Lieutenant Grace for HIS sit-rep doctor. You are on MY ship, and I am in charge here, not you."

Jason watched the doctor open her mouth and then shut it a couple times as the Captain waited for a rebuttal that never came. Sensing that the good doctor would wait her turn, Jason rattled off his report.

"Sir, we were on the continent maintaining our overwatch and distance as Doctor Chase requested when she radio'd in talking about a helicopter. I responded, letting her know our helicopter was docked with the Trident. Shortly after, the Bridge radio'd me, warning us of the unidentified aircraft."

"My team and I immediately went into action, and I told the Doctors to stay put. My team and I took out the three helicopters. But, our fire to move the helo blocking Chase from reaching my team disabled the tail rotor, causing it to spiral and land on Fletcher and the shrapnel to get Green."

"Then, once that was dealt with, a sniper took out Yew, and we were pinned down until Thalia showed up and gunned down the remaining enemy combatants. Valdez and the rest of my team are searching the battlefield for identifying information on our attackers, sir."

Percy nodded his head.

"Thank you, Lieutenant. You are dismissed. Go check on your men and bring Doctor Castellean with you. I think he is going into shock."

Jason looked at the blonde in question and saw him swaying on his feet, sweating, and breathing rapidly. Nodding his head, he put the doctor's arm around his shoulder and led him to the door. He opened it up before pausing in the doorway as he remembered something from the battle.

"Captain."

The man turned to look at him with an eyebrow raised.

"I forgot to mention when the helicopters first arrived. Doctor Chase's work was about a dozen feet away from her. Instead of getting to safety, she went for that case and protected it more than she did herself."

The Captain's eyes widened slightly with that new information. With nothing else to add, he finished helping Doctor Castellean out the door before shutting it and helping the man get to the med bay.

Passing Piper McClean along the way, who looked at him with worry. He gave her a smile, whispering to her as he passed.

"Meet at our spot in an hour."

The girl nodded, and Jason continued helping the shocked Doctor to the med bay.

XX

Annabeth Chase watched Jason and Luke leave the room and felt a pang of worry in her chest. She hoped Luke would be okay. He was practically all she had left at this point. Taking a second to steel herself for the coming conversation, she turned her attention back to Captain Percy Jackson.

"Luke will be okay. I've seen his case a dozen times. He just needs to take some time in a low-stress environment."

Annabeth can say she was honestly not expecting that to be the first words out of his mouth but appreciated the sympathy after the way he yelled at her earlier. Although she supposed she understood it some if she tried to look at it from his perspective.

Two of his soldiers had died, and his ship had been attacked. He didn't know the real reason behind their mission to Antarctica, so to him, the surprise attack was an act of war. He was in uncharted territory right now and had the burden of being the leader.

"Thank you, captain."

He waved off her show of respect, which shocked her slightly, but then again. She supposed she didn't speak to the man besides a quick conversation before they set out on their mission. Something he iterated with his following words.

"Don't call me captain. I'm no different than any of the other sailors on board this ship. You would know that if you had said more than two words to me during this entire journey."

She chuckled, taken aback by his honesty and modesty. Percy joined her, and she could see some of the stress from the last several hours exit his body as he laughed. She could even feel some of her own stress leave her body.

Taking a breath, she smiled at the captain.

"Thank you, Ca- I mean, Percy. I needed that."

He nodded, but she knew the conversation was going to get serious as his shoulders straightened, and he looked her in the eyes.

"You're welcome, Doctor Chase. But I think it's time I learned why you're actually on my ship and why those attackers were after you."

She opened her mouth and then hesitated before powering through. If things back in civilization were getting bad enough that someone thought it was a good idea to attack a U.S. Navy warship, then she doubted she'd be in too much trouble for revealing the mission's true purpose.

"Despite what I told you when we talked when I first boarded your ship, I am not here studying some birds and their connection to Small Pox. I am here looking for the primordial strain of a virus that was discovered eight months ago in Africa that we are calling the K. Virus."

"It was unlike anything we've ever seen before and was highly contagious. It would take control of the human body's nervous system before killing its host within twenty-four to forty-eight hours from the time of infection."

Percy's eyes widened slightly, and for the first time, Annabeth noticed his eyes were an unusual sea green. She wasn't one to talk, however, since her eyes were a unique grey color. Still, she couldn't help but wonder what the chances were that two people with abnormal eye colors were on the same ship together.

"Be honest with me, doc. What's the worst-case scenario of this virus look like? What could we be walking into getting back home? Because people don't just attack a U.S. Navy warship."

"I... I.. Don't know. When I met with the President about this, they told me that Luke and I would also need to go radio silent. At that time, from what we were told, the virus was contained to South Africa and Egypt, with small pockets in Asia and Turkey."

"The had the potential to become a global pandemic, and the United States didn't want a repeat of COVID-19, only deadlier. So, I guess the worst-case scenario is that the virus has become airborne and infected most of the world."

She could hear Percy take a deep breath as he ran a hand through his messy hair. Annabeth had to give it to the captain. He was taking the news that the world might be fucked surprisingly well. She could practically see his mind work through a thousand possibilities a minute as she waited for him to speak up.

"Okay, thank you for trusting me with this information. Who else knows the truth?"

"Just you, me, and Luke."

Percy nodded his head. "Good, let's keep it that way for now."

Annabeth's response was immediate and slightly hysteric, completely forgetting she was arguing the orders from the captain of the ship she was on.

"I want to tell Jason. Two of his squadmates died, and a third is barely hanging on because they protected me over themselves."

Percy's face went from stern to slightly sympathetic as he put a hand on her shoulder. Something she didn't realize she needed until he did, and she felt tears start to fall from her face as the reality of the last several hours set in.

The captain's voice was solid and steady, something Annabeth desperately needed at that moment.

"As callous as this may sound, they were doing their jobs, Annabeth. Before anyone else knows, I need to get a better understanding of what's going on in the outside world right now. I promise you when the time comes, I'll let you break the news to Jason and his team."

She nodded her head, and he removed his hand from her shoulder. Annabeth took a shuddering breath to get control of her emotions, not realizing how upset she had gotten at the thought of not telling Jason and his men the truth.

Once she was done, Percy spoke again. His voice was calm and understanding.

"Go get some rest, Annabeth. You need to take some time to deal with the attack you went through. Even veteran soldiers would struggle if they were in your shoes right now. If you need someone to talk to, I'm here for you, okay?"

Annabeth nodded

"Okay, thank you, Percy. I'm sorry for not talking with you more these past six months."

He gave her an easygoing smile as he waved off her apology.

"It's all good. Just invite me for tea next time."

Annabeth couldn't help herself but laugh. She saw Percy chuckle while she laughed till her stomach hurt. What he said wasn't even that funny, but for some reason, she thought it was hysterical.

Maybe she was losing her mind, or perhaps this was just how her body was dealing with all the events from the last hour. But it felt good to laugh.

It took a second to get control of herself. But once she did, she was left feeling incredibly tired. She quickly left the captain to his own devices before finding her bunk and practically falling into it, going to sleep within seconds.

Percy Jackson watched Annabeth leave before letting out a long sigh. If what she said was true, and he was inclined to believe it, then it was imperative that he get in touch with command as soon as possible.

Making his way over to the Ship Communications Officer's station, he sat down and worked on bringing up a secure channel back home. It took a minute to remember his training on the process, but once he did, he quickly established an uplink to the Pentagon.

"This is Trident 1 radioing for Command, over."

Percy waited for a full minute as nothing but static filled his ears before double-checking his work. Seeing nothing wrong, he waited another thirty seconds before trying again.

"This is Trident 1 radioing for Command, over."

The second he let his finger off the talk button, static once again filled his ears. He could feel his heart rate quicken as he ran through all the possible scenarios for why the Pentagon wouldn't be responding in his head.

Taking a breath to calm himself, he followed protocol and worked to establish an uplink on the subsequent fallback frequencies. He felt his panic rise with each failed response until he tried the last military channel.

Its use was authorized only when the country was at Defcon 1 and was hardwired into the President's Bunker. He wasn't quite sure how to feel as he established the uplink, knowing that if no one picked up on this channel. Then, he would have to assume that the United States Government had fallen.

With a shaky breath, he pushed down on the talk button and spoke the same line for what felt like the thirtieth time.

"This is Trident 1 radioing for Command, over."

He felt dread building in his gut as he released the push to talk, and static once again filled his ears. Once a minute passed with no response, he felt his heart sink until the static cleared, and he heard a voice on the other end.

"Trident 1, this is Command, over."

Percy was pretty sure he had never felt so relieved in his life as he let out a huge breath.

"Command, I just spoke with Doctor Annabeth Chase, and she is telling me that the true purpose of our mission, which was given directly to her by the President, was to discover the primordial strain of some virus. Is that true?"

Static blared through the channel again before clearing as the same person as before spoke through.

"Trident 1, I believe it best to establish a video feed. A lot has happened in the last six months."

Percy thought it was odd but wasn't about to deny the request. It took him longer than he'd like to admit to remember how to move a radio transmission to a call. However, what he saw surprised him once he brought up the video feed.

The Secretary of Homeland Security was on the line and worked worse for wear. She, and by extension, everyone else on the screen, looked to be extremely thin and pale. Before he could even speak, the Secretary, Regina, if he remembered correctly, beat him to it.

"I know, last you heard, I was the Secretary of Homeland Security. The President died three months ago and the Vice President two weeks later. I was the next member in the line of succession who tested negative for the virus."

"What's left of the Federal Government is holed up with myself in the presidential bunker. Our resources are running low, and the power grid is starting to fail. Our communication is getting extremely spotty, so please tell us now, does Doctor Chase have what she needs to make a vaccine."

He breathed as the magnitude of the situation set in before compartmentalizing like Officer's School taught him.

"She believes so, Ma'am."

He could see the spark of hope in her eyes as his words set in.

"Good, we are sending you coordinates to a secure bio-lab off the coast of North Carolina. Be cautious, Captain. From what we are hearing, the United States is the last functioning government left."

"And most of our population, along with our armed forces, are dying or are dead. We have no allies, and we have no enemies. The Rules of Engagement have changed, and your mission is to ensure Doctor Chase can safely create a vaccine or cure no matter the cost."

He nodded, understanding what she was saying as she continued.

"Unfortunately, that's all the information I have at the moment. We haven't been in contact with our above-ground team in three weeks, and it's getting harder and harder to reach the world outside this bunker."

Suddenly, a loud bang came through the speakers. Percy instinctively turned his head towards the ship's door, expecting it to have fallen off before he registered that the sound had come from the President's end.

"Ma'am, what was that?"

Her face looked panicked, and Percy felt dread in his bones as he heard the familiar sound of gunfire through the speakers. The President turned to stare at him, a true terror in her eyes.

"Cap-"

Then, static. Percy slammed his fist on the metal console in frustration. Trying desperately to create another connection with the President's Bunker to no avail. What remained of the Federal Government had just been attacked, and there wasn't a damn thing he could do about it.
