AN: So hello everyone, this is a tester chapter of thoughts, one I am publishing to try out some ideas I had and get some feedback I can use going forward. IT is of course a Percy Jackson/ Game of Thrones story, based mostly on the TV programme, but also using a few bits and pieces from the books where they fit and are appropriate.

That being said some of the themes in this story, and one or two plot points and elements have been inspired by a computer game I used to play years ago, called Warcraft Reign of Chaos, and the Expansion Frozen Throne. With these elements predominantly being to do with the storyline, as oppose to anything else. This story focusing on Percy Jackson.

Either way I hope you give the story a chance and enjoy it. Plus I would love to hear some feedback, as I've tried to add some more context to this story than I did for my others, as a tester of sorts. Thanks for reading, hope you enjoy.

Disclaimer: I do not own Percy Jackson or Game of Thrones.

Chapter 1

(In Greece, on the slopes of Mount Olympus)

It was hot and dry, almost intolerably so, though considering this was mainland Greece in summer then maybe that wasn't all that surprising. At present there were two armies currently duking it out on the slopes of Mount Olympus, with one of the armies, the larger one by far, being the seemingly, never ending forces of Gaia, the semi slumbering Primordial Goddess of the Earth.

A thronging, mass of monsters that spread out as far as the eye could see, a seemingly unstoppable horde that had been released from the bowels of Tartarus and sent to the mortal plane, where they had spread out, causing untold chaos, death and destruction as they fell upon anything they came across, unleashing their wrath and fury on both the mundane and supernatural alike, uncaring that most humans were unaware of their existence, or that the divine world had been hidden by the Mist, a magical veil, for centuries now.

With this unholy horde being led by much mighty beings, such as the Gigantes, the giant children of Gaia and Tartarus, born for the single purpose of killing and replacing the Olympians. Most of whom were fighting to fully awaken their mother and fulfil her plan of sending the world back to how it was in the First Age, the primordial age. With a number of pissed of Titans and Minor Gods lending their aid to cause, either fighting for revenge on old slights, or for position in the new world order that Gaia sought to create.

Standing against this overwhelming horde was the gleaming legions of Olympus. With hundreds of Demigods, Roman and Greek alike, wearing burnished armour, and gleaming weapons forged from either Celestial Bronze or Imperial Gold leading the way. With these men and women being back up by platoons of Dryads, Satyrs and Nature Spirits wielding spears, bows and elemental magic, and by units of armour clad Cyclops loyal to Atlantis, and whole array of other soldiers of Olympus, including some on Pegasai and Griffins.

Furthermore this small, but powerful forces of Olympus were being supported by masses of undead soldiers, soldiers from every era, with Greek Hoplites fighting alongside Napoleonic rifle men and modern day Special Forces units. With mighty heroes from the past like Achilles, Ajax, Alexander the Great and Bruce Lee adding their strength to the mix, bolstering the forces of Olympus as they fought back against Gaia's vast army. With their fight extending and expanding every hour that it last, as the fighting spread out, over land, sea and air for miles and miles in all direction.

With any mortal unlucky enough to get caught up in it dying, even as the Mist itself began to crumble and humanity was exposed to the supernatural for the first time in centuries, affirming once and for all, for all those naysayers out there, that the age of the gods was not just mythology made up to scare children and manipulate the masses, but a very real, tangible and deadly thing.

Near the head of the army of Olympus, fighting in the front lines, alongside gods both major and minor, was one Percy Jackson. The dark haired, green eyed son of Poseidon wearing a chain mail hauberk of Celestial Bronze, with an Imperial Gold cuirass, pauldron and gauntlets over the top.

His sword Riptide held in one hand as he fought like a berserker, throwing all caution to the wind as he hurled himself into the very thick of the fighting, the air around him coalescing into a miniature storm, and the ground at his feet trembling as he unleashed his full might on his foes.

Fighting directly alongside his son, occasionally sending him concerned looks, was a similarly dark haired man, with sea green eyes and tanned skin. With this older man wearing a set of greenish armour, and wielding a massive golden trident, one which practically radiated with untold power as he smote any monster, giant or Titan foolish enough to face him, working in perfect synch with his son, Percy, as the cut a swathe through the hordes of Gaia, heading for the Earth Goddess herself.

This was Poseidon, the God of the Sea, Earthquakes, Soil, Storms, and Horses, the Earth Shaker and the King of Atlantis, and currently he was concerned. Not about the fight though, as the battle was going well, it had lasted for nearly four days now and the forces of Olympus had prevailed thus far, cutting their way through the masses of monsters, almost reaching the heart of the horde, the mountain of Olympus where Gaia was still slowly awakening.

No, instead his concern was for his son, Percy, the last year had been very hard on the teen. Firstly he had been kidnapped from his home by Hera, that bitch, only to then have his memories wiped and be kept in stasis for months, after which he was then sent to the Roman Camp, all for the Queen of Olympus's overly convulted plan to unite the Greek and Roman Demigods.

Following on from that he had been given a quest by Mars the God of War, and had then been sent to Alaska of all places, the land beyond the gods, where he was supposed to unchain Thanatos the God of Death, the idiot who had gotten himself captured, stopping him from reaping the souls of those killed, and policing the borders of the Underworld, which of course had made the monsters serving Gaia practically immortal.

After that Percy had then returned to the Roman Camp, Camp Juptier, his memories still intact as he had then gone with six other Demigods to Italy, in the Old World, all so he could find that bratty goddess, Athena's, statue, so peace could be made between the Greek and Roman Demigods, all so they could ally together and defeat the slowly awakening Gaia.

Of course not everything goes to plan, and although the Demigods had found the Athena Parthenos, they had also fallen into a trap. Which had led to Annabeth, Percy's girlfriend, and a daughter of Athena, to fall into the depths of Tartarus. Which had naturally led Percy, the overly honourable and loyal idiot he was, to jump in after her.

From there things had only gotten worse, as from what Poseidon had managed to find out from reading the minds of Percy's Demigod comrades, and his brief conversations with Hera and Athena, the girl Annabeth had died instantly from the fall, with her being killed upon impact as she fell hundreds of miles and through the dimensional gap which separated the mortal plane from Tartarus, and directly into the unforgiving terrain of the Pit.

Percy though, he had survived the fall, with him instead landing in one of the Rivers of the Underworld, which broke his fall. And after that, well Poseidon didn't know what happened to Percy after that, with three weeks on the mortal plane having passed before the teen returned, with Percy never saying a word about his ordeal.

But whatever did happen down in the Pit had changed him, making his son colder and angrier, and more prone to violence, with his emotions being tumultuous and unstable. Though considering they were in the middle of a war being violent and angry was probably a good thing, he could harness that anger and use it, plus all the fighting would hopefully be cathartic for Percy, otherwise steps would have to be taken.

Poseidon suppressed a scowl at that thought, an angry and out of control Demigod might be useful in a fight. But they were also a danger, especially Percy, with him being the strongest Demigod in recent times.

It was for that reason that Poseidon knew that Zeus, his brother, would likely call for Percy to be killed if he didn't regain control of himself. After all a powerful, uncontrollable Demigod was perhaps more dangerous than an out of control god, as gods had to obey certain Ancient Laws, if they wanted to continue existing, Ancient Laws that didn't apply to Demigods.

Poseidon let out a tired sigh at this thought, even as he saw Percy, his favourite son, once again throwing himself into the thick of the fighting, his body covered in golden dust and ichor, and his blade a blur as he slashed and hacked at anything and everything he could. His face contorting into a mask of barely contained rage as he drew on his Demigod powers and harnessed his father's domains, lashing out with highly condensed blasts and blades of water from his free hand, or creating waves of earthen spikes erupt from the ground below his foes feet.

A loud bellow erupting from his lips as he clambered over fallen friends and foe alike as he continued to attack his enemies, driving ever deeper into the mass of monsters, the rest of the Olympian army following his path, with Percy acting as the tip of a wedge formation, one which bored through the enemy hordes.

(Sometime Later)

"Come on! We're nearly there, we're nearly within reach of Gaia!" Percy shouted as he grabbed the blood slickened hilt of Riptide, his other hand coming up to wipe the blood off of his face, smearing it slightly as he then took a gulp of Nectar from the flask he had clenched in that same hand.

"It's been nine days Percy, nine days of continuous fighting!" A bloodied and battered Jason replied tiredly, the two of them currently taking a breather in the back lines, slightly away from the ongoing fighting, some hundred metres ahead of them. "Most of us are running on just Ambrosia and Nectar, we've not slept in days, we're exhausted, we're injured, we can only last for so long!"

"And you're point is?" Percy replied bluntly, his brow furrowing at Jason's words. "The enemy is just as tired, and we've got the momentum, we've been pushing them back for days now. With the Doors of Death sealed, and Thanatos free, they're not unbeatable anymore!"

"But they still out number us a hundred to one!" Jason snapped, frustrated with his frenemies dismissive attitude. "And Gaia is almost awake now, and the monsters of the earth are starting to regenerate faster and faster."

"Then what are you saying, we should just give up?" Percy snapped back at Jason, his brow twitching as he pushed back his fury, after all if they gave up now then all of those deaths, and all of that suffering would have been for nothing.

"No, we should regroup. We need rest, and reinforcements." Jason replied, taking a step back as he saw a flash of rage pass through Percy's cold green eyes. "Even the gods are starting to waver."

"Say we do, say we do back off and regroup. What do you think the enemy will do?" Percy replied harshly, controlling his anger as he instead glared at Jason.

"They'll continue to rampage across the Old World and the New, probably killing millions of mortals as they do so." Jason said with a sigh, his jaw clenching and unclenching as he understood what Percy was getting at.

"No," Percy replied flippantly, ignoring the threat to the mortals for the moment and concentrating on the more pertinent things. "It will give Gaia the chance to fully awaken, she's been on the verge for days now and could fully wake up at any moment, and when she does then she wins. None of us are strong enough to take on a fully wakened Primordial, only another Primordial could. If she wakes up, before Aphrodite forces her back to sleep, then we lose and we will all be wiped out. This is bigger than any of us Jason, this is about the continued existence of our kind!"

Jason grit his teeth as he heard that, his sky blue eyes narrowing as he locked gazes with Percy. The other teen had changed, he wasn't as goofy or happy go lucky as before, instead he was harder and harsher, and above all else he was pragmatic in his thought process and ruthless when it came to taking action.

"Ok fine, let's do it, one last push." Jason nodded after a few moments, ignoring the almost deafening sound of clashing blades and roaring monsters as he instead locked eyes with the blood covered, Percy Jackson, for a moment not recognising the man standing before him, Tartarus truly had changed him.

"Now let's go!" Percy shouted, oblivious to Jason's thoughts, as he instead downed his flask of Nectar, the veins beneath his skin glowing golden as the divine drink flowed through him, a sure sign that his excessive consumption was causing him to burn up from the inside.

Following on from that Percy let out a roar before he charged forward, his armour now scratched, scarred and battered as he once again, shouldered his way to the front lines, throwing himself upon a Lastragonian Giant as he did so and decapitating him with a single swing of his sword, before, without pause he then engaged his next opponent.

(On the slopes of Mount Olympus, sometime later)

"Hyah!" Zeus bellowed as he thrust this Master Bolt out, his Symbol of Power, a weapon capable of wiping out entire countries at Gaia's twenty foot form. A skyscraper sized bolt of lightning erupting out of it, and striking, the tall, matronly looking goddess, striking her pale white skin and sending her tumbling backwards.

"Go to sleep you bitch!" Hades followed up as he whipped his Stygian Iron sword around, the shadows dancing as the sun began to set, with thick tendrils of shadow rapidly binding Gaia's limbs, dragging the goddess down.

"Sleep!" Aphrodite commanded as she launched herself forwards, her silver armour gleaming as it caught the last rays of sunshine, even as she grabbed a hold of Gaia's thick brown hair, clinging on as she screamed in the goddess's ear, putting all of her considerable power into that one word. Causing the simple command to be so powerful that it put nearly all Demigods and monsters who heard it to sleep, and even caused a few of the other, minor gods, to nearly fall.

"Keep it up, Aphrodite!" Demeter called out as she saw Gaia's glazed eyes starting to close, even as the giant woman's body began to sink back into the ground, the Primordial Goddess slowly losing her physical form and once again merging with the earth. With Demeter helping the process along as she usurped some of Gaia's power, taking advantage of her weakening to once again reclaim her Domains from the elder goddesses control, and force Gaia to return to the earth faster.

As this was happening, all around the base of Olympus both gods, Demigods, spirits and the undead continued to fight off the now declining hordes of monsters. With Percy and Poseidon taking on the last of the giants, even as the rest of the Olympians save Ares and Athena dealt with Gaia, the god and goddess of War and battle strategy instead leading the remnants of Olympus's beleaguered forces against the monsters, driving them back and boxing them in as they tried to wipe them out.

The battle was reaching its twelfth day now, and even the gods were beginning to flag and fall. With Olympus's forces having taken a massive hit since the start of the battle, hundreds of Demigods, Satyrs and Nature spirts now lying dead, whilst still others had been transported away, either due to horrific injuries, or due to just plain exhaustion.

In total Athena had worked out that only ten percent of Olympus's army remained, with this mainly being due to the undead, who never got tired, though the Underworld god's and Demigods who summoned them did, which is why even the legions of the dead were beginning to decline as more and more of them returned to the earth, never to rise again.

Despite this though they were winning, the Gigantes were all but wiped out as were the Titans and traitorous gods, as for the monsters, it was only those directly connected to the earth and Gaia that clung on, and even they were falling now that Gaia was being forced back to sleep, their regenerative abilities, courtesy of the Goddess of the Earth, failing them.

"Come on Percy, we're almost there." Poseidon muttered as he ripped his trident out of Orion's back, leaving the giant to collapse into dust, even as Percy collapsed to his knees behind the now dead giant.

His blade Riptide still in hand, though now it was little more than a hilt with about two inches of blade left after Percy had broken it when fighting the Titan Hyperion with Frank, Jason and Leo. A fight that they had won, but just about, and with heavy sacrifices as both Leo and Frank had lost their lives in the fight. The recently revived and weakened Titan Lord of Light almost proving himself too much for the four exhausted Demigods or beat.

"Ok." Percy gasped out, spitting out some blood as he did so, before he looked up at his father revealing his pale skin, and the dark rings under his eyes.

Pushing himself to his feet, Percy's body almost gave way on him as he momentarily stumbled forwards, his hands shaking uncontrollably as he then pushed himself to his feet, pushing back his fatigue as he instead tried to focus on the task at hand.

"Ok, let's go." Percy said, more blood spilling from his mouth as he did so, his blood now steaming and flecked with gold, a sure sign that he had now consumed too much Nectar and it was eating away at him from the inside, something which was fatal to Demigods, no matter whose child they might be, or how strong they were.

"Percy!" Poseidon said stepping forward and catching his son before he collapsed.

A ragged gasp left Percy's lips at this, before he once again pushed himself to his feet, ignoring Poseidon as he pushed himself forward, heading directly for Gaia.

"Enough!" Poseidon snapped as he saw this, grabbing Percy by the back of his shirt, his armour now beyond repair, shattered and littered across the battlefield. "If you continue as you are, then you will die! In fact you're already nearly dead! You need to stop now Percy, you've done enough!"

"No," Percy replied, too tired to put any real anger into his words, as he instead continued to struggle futile against his father's grip.

Poseidon rolled his eyes at this, his son was about as strong as a kitten right now. "You've done your bit Percy, leave the rest to us."

"No," Percy tried to say again, only this time Poseidon reinforced his point by knocking his son out, Poseidon's callused hand resting on back of Percy's head for a moment, as he then reversed the flow of blood to his son's brain for a moment, starving it off oxygen and forcing him into unconsciousness.

Laying his son down on the battlefield, ignoring the remnants of fighting around him, Poseidon sent his son a tired look. He had never really been much of a father to Percy, hell, he hadn't been much of a father to any of his children, but even he knew when enough was enough, and when he needed to step in and stop his child from killing himself, with his own self-destructive behaviour.

Looking away from his fallen son, Poseidon looked off in the direction that his siblings were facing off with Gaia. His usually cheerful and happy go lucky expression, hardening as he looked over the plain of golden dust around him, and at the thousands of bodies that littered the sides of the mountain.

The battle was nearly over, just a little more and they would seize their victory and defeat Gaia. After which things would hopefully start to return to normal as Olympus recovered from this conflict. It might take years, but Olympus would recover, of that he had no doubt.

Of course some would likely hold onto the scars of this conflict for the rest of their lives, his son Percy for example. It was with this thought in mind that Poseidon turned around and looked back at his son, only for his eyes to then widen when he found Percy's body gone.

"Percy?!" Poseidon shouted, looking around in all directions as he did so, searching for his errant son. "Percy, where are you!?"

Only for him to see nothing but the bodies of the dead and the mounds of gold dust that signified fallen monsters and immortals, the Sea God's shouts soon getting drowned out by the sudden sounds of exultant cheering and shouting some distance away, as Gaia was finally forced back to sleep, her forces crumbling, and the threat she posed to the world ending.

"Atropos, why did you do that?" Clotho asked, her raspy voice cracking slightly as she looked over at her sister, noticing as she did so how the other woman's face was devoid of emotion as she continued to look down on the now ending battle from above. "It was not his fate."

"None of this was his fate," Lachesis replied to her sister, on Atropos's behalf, her own voice just as raspy, as the three women, the Moirai, the three Fates, continued their eternal vigil. "The girl was not supposed to die, and the two of them were supposed to survive Tartarus. The fate of Perseus Jackson had already been corrupted by someone else, when Annabeth Chase died. Now that he has fulfilled his purpose this is probably for the best."

"Still we are not to intercede, we are watchers, nothing more." Clotho replied, her tone not changing, even as she started pondering about just how Percy Jackson fate was thrown of course to begin with.

"Even if the fate we allotted him at his birth became unravelled." Atropos finally spoke up, looking down at the other two. "Even when we know what he will go on to do?"

"But we don't, his fate was not yet set." Clotho responded, knowing as she did, that because of the events in Tartarus, Perseus Jackson's fate was still in flux, as were many of the events the future held, and the fates of the other Seven Heroes of Olympus.

"No, but we have seen what his future may hold and so I acted, and have cast him out." Atropos retorted, not a hint of doubt on her face, after all she, like her sister's, had seen the things Perseus could have gone on to do, corrupted as he had become after his time in Tartarus.

"It is not our place to decide that, and now because of your actions he is gone, gone from this world and now beyond our vision, and out of our control." Clotho said, her tone turning slightly impatient now at her sister's intransigence.

"It is for the best. I decided to cast him away, as he is too unpredictable, too much of a variable to have around, either on the mortal plane or in the Underworld." Atropos continued, her voice still devoid of doubt. "I saw what his fate held and made a decision, what is done, is done."

"So that is it, you just wash your hands of him?" Clotho asked irritably. "Who knows where he ended up when you cast him into the dimensional gap."

"Sister, Atropos is right, what is done is done. Perseus Jackson's fate is no longer our concern." Lachesis spoke up again, trying to bring peace between the two bickering sisters. "Now come, the battle is over and we still have a lot of work to do. Even now the life threads of millions of mortals need to be spun, measured and cut."

"Besides, with him no longer being in this world, he no longer has a connection to Poseidon's Domains and will forever be weakened, what damage can he really do when just relying on his own innate power, afforded him by his father's blood?" Atropos questioned, her tone still as empty and emotionless as ever. "Now let's continue our work, Lachesis is right, this conflict has killed many, and many more lives still hang in the balance."

Clotho scowled at that but nodded. "Very well, what is done is done, I will say no more about it. Though I dread to think what Perseus Jackson's fate will now be."

The other two did not respond to that, both of them putting the fate of Percy Jackson out of their minds, as now he was no longer a part of their world, and no longer under their jurisdiction, and so therefore was no longer worth thinking about. Clotho though didn't let it go, despite her words, her mind instead going over many plans and plots for the future.

(Elsewhere, with Percy)

Opening his eyes Percy Jackson found himself lying in a mound of ice and snow, his body shaking uncontrollably, even as it began to go numb. The freezing cold wind blowing around him, enshrouding his broken and damaged body with snow and ice.

Opening his lips a groan escaped Percy's mouth, sending up a cloud of misty air from his mouth. He was dying, this he knew. Already he could feel the cold seeping into his bones and his life-force slowly ebbing away.

How it came to be that he would freeze to death in the middle of Greece during summer he didn't know, but neither did he really care. He was dying, and he was alright with that.

Living he had found was painful, Tartarus had shown him that much. Even now, lying on his deathbed in a mound of snow and ice, he could still feel the burning heat of Tartarus, and the taste of the River of Fire as he drank its waters. And even above the whistling of the icy cold winds, he could still hear the echoes of the screaming occupants of Tartarus echoing in his ears, monsters and mortals, foul creatures who had done terrible things and were rightly suffering for it.

Death after that, was almost relief for him, at least then he could find a sense of peace, an escape from the nightmares that even now haunted him. There was a reason he had pushed himself so hard in that final fight against Gaia after all, and it was not just so he could slaughter monsters, it was an escape, a distraction from dwelling on the horrors he had seen and heard in Tartarus.

Percy opened his eyes at that, his vision blurring as he lost feeling his limbs, his body no longer shaking or feeling cold as it instead almost began to feel warm, no doubt hypothermia.

Looking up into the pitch black sky above, Percy's eyes trailed over the stars, trying to pick out the constellations he knew, who knows for his actions he might even end up receiving a constellation of his own like Zoe Nightshade did. Now that was a nice thought.

Moments later though, Percy frowned, his muddled mind spinning in confusion as he found himself being unable to recognise a single constellation in the night sky.

Before he could think any more on this though, the crunching of footsteps on snow sounded out, attracting the dying Percy's attention as he tore his eyes away from the night sky and instead looked over at the source of the disturbance.

"Wh-" Percy tried to say, his brow furrowing in confusion as he found himself looking at an unfamiliar being, one with skin as white as snow, and cold icy blue eyes, and instead of hair he instead seemed to have a crown of horns. On top of that the creature's features and characteristics, were almost alien to him, and his black armour unfamiliar. But one thing Percy knew, was this creature was powerful, terrifyingly so.

Tiling its head to the side as it looked down at him, the creatures icy blue eyes locked on Percy, analysing him, almost as if it was weighing up his worth.

Struggling Percy tried to raise his sword, a just hilt though it might as well be, up so he could at least defend himself. Only for those struggles to be futile as his entire body was now numb, unfeeling and out of his control.

In response to this the creature smiled, which was probably more terrifying then if it had screamed at him. With its actions revealing a row of gleaming white teeth, its blue eyes glowing with power as it leant forwards towards Percy's limp, unresponsive and dying body.

The creature extending a pale white hand towards him as it did so, its fingers extending, before moments later its sharp, darkened nails dug into Percy's chest, piercing the flesh right where his heart would be.

Almost immediately, the hypothermia based warmth Percy had once been feeling vanished, replaced instead by an almost burning cold, as it felt like the blood in his veins froze, with the feeling then suddenly returning to all of his limbs and bodily functions in an instant.

Which was unfortunate as Percy then opened his mouth and let out a scream of agony, his body contorting as he felt an unfamiliar energy burning through his veins, his green eyes widening as he did so, his right one rapidly turning the same icy blue colour as the creatures, even as his other resisted, the Demigodly blood in his body trying to resist this foreign energy invading his system, even if the human half of him submitted at once and was devoured.

Percy wasn't sure how long this went on for, it could have been minutes, or it could have been hours. But it eventually stopped, the pain receding even if the cold didn't, though it did become far more tolerable, almost unnoticeable.

What wasn't unnoticeable though, as he lay on his back in the snow, looking up into the terrifying eyes of the creature above him, was the slow deadening of his pain, the almost ethereal whisper he could feel echoing around his head, and the sudden realisation that he was no longer dying.

AN: So what did you all think? Did you enjoy it? The White Walkers have always been something I find interesting, with my theory for the end of the Game of Thrones series being that the White Walkers will win and everyone else will die. For which reason I have been wanting to explore their existence and motivations and add in some development of my own. Plus I always think of Death Knights when I think of White Walkers.

That being said my plan for this story is quite loose at the moment, as there is an important part of the plot I need to make a decision on. For which reason I would really appreciate it if I can use someone as a sound board for this plot point. Someone who doesn't mind potential spoilers.

So yeah, other than that I hope you enjoyed it and leave a review, they are really useful and really motivates authors.

Thanks for reading and I will see you later.
