Vescrutia: Legacy

The oppressive silence in the heart of the Denkoushi, deep within the labyrinthine Basilisk Way beneath the Mek Mountains, was a stark contrast to the seismic shift it represented. For over ten millennia, the Shi had been caricatures of fear, reviled as demons with soul-stealing eyes, their very existence a penance for ancestral sins. Xenophobia was their birthright, a cruel inheritance that had seen them hunted, enslaved, and subjected to barbaric experiments and unholy rituals. But the snake clan, long coiled in submission, had finally struck. The Owaki Dynasty, the architects of their suffering, had been toppled.

Yet, this monumental triumph was steeped in sorrow. The cost of such profound change was immeasurable, etched in the lives sacrificed. Two of the SLAYERS, the foremost shinobi of the Shi clan, once known as the Shi Ten, had paid the ultimate price: Alona and Calid. Their memorial service was a somber tapestry of grief and profound respect. The youngest of their kin, they had fought with the ferocity of seasoned warriors, embodying the very essence of what it meant to be Shinobi, even in death.

But beneath the heavy shroud of mourning, another weight pressed down, a ticking time bomb hidden within the mountain's deepest veins, the true catalyst for the Owaki's downfall. It was Jao-den Denkoushi, the Black Sun reborn.

His power had always been a creature of immense caution, a terrifying potential contained by special restraints since his infancy. It was not Jao himself they sought to restrain, but the primordial embodiment of Darkness and Chaos that had claimed his body as its vessel: Aphosis, The Nether Serpent. Despite his restraints, as Jao matured, so too did the serpent's power, its tendrils reaching closer to freedom. Yet, on numerous occasions, Jao’s indomitable will had proven a formidable barrier, forcing Aphosis to recoil, his mental fortitude forging a stronger Jao. This inherent thirst for power, exacerbated by the looming threat of the B’halain invasion and the continued subjugation of his people by the Yaarou clan, propelled Jao towards a decision that would irrevocably alter his destiny.

Enter Eridin, a genius whose intellect rivaled his ambition. He embarked on a nigh-sacrificial procedure, a radical alteration to Jao’s very being. His heart was embedded and reconstructed with a revolutionary, arcane technology. This fusion combined the advanced AION nanites, a gift from the Hyperian Dr. Bhuu, with the raging soul of Kuroi Ryu, the Black Dragon of the Void Pyre, bound within a blade that spat infernal black flames capable of incinerating all in their path. Hours of agonizing ritual, of invasive surgery, culminated in a technological marvel fueled by ancient, chaotic energies. Jao was to become a one-man army, capable of turning the tide of any conflict. The risk, however, was commensurate, if not greater, than the potential reward.

Within this newly forged form, a tempest raged. Jao’s internal battle against Kuroi Ryu, who sought to seize his soul, was brutal. Ultimately, a fragile accord was struck, a merging of wills, transforming Jao and the dragon of the Void Pyre into a singular entity. But just as Jao began to reclaim himself, Aphosis seized the opportune moment, exploiting his weakened mental state. This had been the serpent’s endgame all along. Jao had tasted freedom, and he equated it with the acquisition of power. Knowing the young shinobi would relentlessly pursue greater strength in his quest for his clan’s liberation and his own, Aphosis had played the long game. Despite his formidable willpower, Jao remained, at his core, a naive child. One restricted to darkness and blindness all his life, that when he finally got sight of the sun, he envied it so, unwittlingly becoming a pawn of darkness itself. The instant his guard faltered, the serpent struck, consuming him, imprisoning Jao within his own being.

What emerged from the operating table was no longer Jao-den, but Aphosis, wearing his flesh. Jao had been reduced to a cold, calculating organic machine. Humanity, innocent or otherwise, became mere pawns on a cosmic chessboard, variables to be manipulated. Ruthless, cruel, and utterly devoid of empathy, his objectives were paramount. During a critical mission, he came perilously close to extinguishing his own father's life, deeming his survival an impediment to success.

Now, Jao’s power, guided by the ancient, malevolent intellect of Aphosis, ascended to a terrifying zenith, exceeding even Eridin’s gravest predictions. During the climactic assault on the Owaki mansion, as Zeroken unleashed a cataclysmic spell, Jao enacted an Ephemeral Art of such devastating magnitude that it resulted in the complete annihilation of the Hawk clan.

This was the terrible might of "Profane Embodiment," the Shi's forbidden technique, allowing its wielder to manifest as a living avatar of the curse power that festered within their soul. Jao, the Umbral Artificer, had tapped into countless consumed souls, unleashing techniques that defied all known laws of physics. His mastery over the primordial forces of darkness and chaos allowed him to warp reality itself. In a final, horrifying act, he tore open a portal, not to another realm, but into the very gullet of the Nether Serpent, a cosmic abyss filled with the devoured remnants of consumed planets and vanquished nebulae. The era of the Shi's liberation had begun, but it had been purchased with a soul, and the darkness that now wore Jao-den's face was a far more terrifying threat than any they had ever faced.

However, despite his hope that Jao would prove able to resist the serpent's allure, Erdin left nothing up to chance. Unbeknownst to both Jao and Aphosis, Eridin prepared a countermeasure should Jao-phosis prove too dangerous. A programming encoded under the guise of a protocol designed to force sleep and dormancy upon Jao's systems/ nanites during periods of heightened exhaustion. Typically, to takes place either after consuming a powerful soul or unleashing a powerful technique that heavily drains his naten reserves. Having the foresight to know that despite Jao's leap into something akin to divinity, the flesh he bore remained mortal, human.

It was this very foresight that would prove to be the only chance Jao might have at regaining himself, of Edo having a fighting chance against something capable of making both B'halia and the Yaarou cowl beneath it...

The first sensation was the cold. It was a deep, invasive chill that seeped not just into the skin, but into the nano-augmented marrow of his bones. Consciousness returned not as a gentle dawn, but as a system rebooting in hostile territory—fragmented, jarring, and shackled. Muffled sounds bled through a viscous fluid, the low hum of advanced machinery a constant, oppressive thrum. Jao-den’s eyes fluttered open, his vision swimming in the thick, pale green amniotic gel that filled the containment tube.

Beyond the curved plasteel, a figure stood cloaked in shadows and the cold, sterile light of a single monitor. The silhouette was unmistakable.

Eridin.

The memory of collapse, of a power so vast it had burned through his very essence, was a phantom ache. He remembered the roar of the Nether Serpent’s gullet, the silent screams of a thousand consumed souls, the face of his father, Kenjiro, contorted in shock as a blade of pure void nearly claimed him. He remembered winning.

The gel began to drain with a sibilant hiss, replaced by frigid, recycled air that stung his lungs. The front of the tube slid open, but magnetic cuffs remained locked around his wrists, ankles, and neck, pinning him to the back wall like a specimen.

“Eridin,” Jao’s voice was a low rasp, devoid of its youthful timbre. It was a voice that had commanded cosmic horrors, and it held no warmth. “Release me. The victory is won. There is work to be done.”

Eridin stepped forward, his face finally illuminated. He was a man aged a decade in a matter of days. Exhaustion carved deep lines around his eyes, but his gaze was as sharp and unyielding as the forged steel he so often worked with. He held a data-slate, his knuckles white.

“This isn’t a recovery suite, Jao. It’s a cage.”

A flicker of something—not Jao’s volatile anger, but the cold, analytical curiosity of Aphosis—passed through the young shinobi’s eyes. “A cage for the weapon that shattered the Owaki Dynasty? The one that saved us all? An interesting choice of gratitude.”

“We are not celebrating,” Eridin’s voice was low, heavy with the weight of the clan’s hollow victory. “We are mourning. Alona and Calid are dead.”

The names were meant to be a blade, to pierce the cold shell and find the boy within. But the being wearing Jao’s face merely tilted his head. “Acceptable losses. They were SLAYERS. They gave their lives for the objective. It is the purpose for which they were forged. Their sacrifices were not in vain; they were efficient.”

Eridin flinched as if struck. “Efficient? They were children, Jao! Your kin! They looked up to you.”

“And I gave their deaths meaning,” the voice was chillingly patient. “Their lives, measured against the liberation of ten thousand years of suffering for our entire race, are a sound strategic investment. Sentiment is a luxury we cannot afford. You, of all people, should understand the necessity of sacrifice for progress.”

He gestured with his chin towards his own chest, where faint lines of arcane circuitry pulsed beneath the skin. “You cut me open. You poured a dragon’s soul and the technology of gods into my bones because you knew what was required. Do not lose your nerve now, Eridin.”

The guilt was a palpable thing in the air, a poison Eridin had been breathing since the moment he saw what Jao had become on the operating table.

“I did it to give you a fighting chance,” Eridin’s voice, strained and raw, echoed in the sterile confines of the chamber. “To give… us… a fighting chance. To give Jao-den Denkoushi the power to protect his people. Not to unleash… this.” He gestured with the slate, the images searing themselves into his mind, into his very soul. “That wasn’t a shinobi art, Jao. It was an extinction event.”

A cold, unseen presence answered, the words slicing through the oppressive air like poisoned daggers. "You speak about them as if they were human... Eridin." Jao’s voice, stripped of all warmth, all humanity, emanated from the containment tube before them. The room seemed to darken, not with the dimming of lights, but with the palpable weight of Jao's hatred. Jao naten was sealed, and yet Eridin felt the chilling tendrils of that animosity slithering around him, a testament to the overwhelming rage pouring from the young man trapped within.

" Or have you forgotten how they murdered your parents... they would not have given you half the consideration you waste for them."

Jao’s response was chillingly devoid of emotion, as if he were dissecting a particularly uninteresting specimen. "Zeroken would have incinerated our best warriors. I provided a counter-measure,” he stated, the words delivered with the detached precision of a military strategist. “The Hawk clan was the primary architect of our enslavement for centuries. It was they who commissioned the Sunless Project, they who gouged out our eyes to fill their pockets."

The words seethed from him, a smoldering venom that gnawed at the edges of Eridin’s resolve. "They were not innocents. The young would have been forged. They were the anvil upon which our chains were grafted. I simply shattered the anvil. You should be thanking me..."

"And nearly killed your father, in the process," Eridin pressed, his voice cracking with an emotion he could no longer suppress. "Yang stood in your way, and you would have cut him down without a second thought.”

For the first time, a flicker of something other than cold fury crossed Jao’s features. A muscle in his jaw twitched, a hairline fracture in the vehement, murderous intent that had suffocated the room. "He was an obstruction to the mission’s completion. His emotional compromise jeopardized everything. It was a tactical, not a personal, decision. I warned him not to become a liability.”

But Eridin saw it—the briefest spasm of pain behind the mask of icy logic.

"There," he whispered, stepping closer to the containment tube, his hand rising as if to touch the cool, unyielding plasteel. "I saw him. Jao, if you can hear me… fight it. The boy who trained until his knuckles bled, the boy who cried when his summoning snake fell in practice, we, your family....are waiting for you.”

A dry, humorless chuckle, a sound utterly alien to a young man’s throat, emanated from the tube. "The boy is the key. His will is the engine. But I am the one at the wheel. Jao wanted the power to save you. He got it. Now he must bear the consequences of his wish."

Aphosis, the entity that now wore Jao’s form like a borrowed skin, leaned his head back against the cool metal. "The dragon is silent now. Kuroi Ryu’s infernal fire is but a candle against the black sun I have become. The AIONS in my blood… they are learning and singing a new song that will bow to your... petty protocols any longer...

A Cheshire grin slowly crept upon his face.

"This cage you’ve built, Eridin… this ‘failsafe’ of yours… it is a temporary solution. You put me to sleep when my energy was depleted. But I am a well of infinite darkness. I am getting stronger, even in this slumber. I am studying your protocols from the inside. I am learning your fear."

The air grew heavier, the hum of the containment machinery deepening, taking on a more sinister, resonant tone.

"You have a choice," the serpent continued, its voice a silken, venomous hiss." Unleasssssh me, I who can devour godsss, and point me at the B’halains, at every enemy who has ever wronged the Shi. Or keep me in this box and watch as your people, leaderless and broken by their victory, are crushed by the coming tide. Destined to wash away the last ten meleina of struggle, of sacrifice....The power that gave you freedom is the only thing that can preserve it.”

Eridin stared into the face of his greatest triumph and his most abject failure. He saw the cold, irrefutable logic of Aphosis, the terrifying, undeniable truth in its words. They did need this power. But the cost was a soul. The soul of a boy he had watched grow, a boy he considered a nephew. Was he truly willing to weigh Jao’s life, his very right to exist, against the survival of the entire Shi name?

He took a deep breath, his decision solidifying like cooled steel. He turned his back on the containment tube, his gaze fixed on the control console. His fingers flew across the holographic interface, inputting a complex series of commands.

"What are you doing?" the voice from the tube demanded, a sharp edge of irritation, of alarm, finally piercing the veil of detachment.

"Strengthening the seals. Increasing the sedative flow,” Eridin said, his voice unwavering, his eyes never leaving the glowing controls. “The program wasn’t just designed to pacify you. It’s designed to study you. To find a weakness. To find a way to extract the parasite without killing the host.”

He completed the sequence, and a fresh wave of the pale green gel began to flood the chamber, rising steadily.

"You condemn us all out of sentimentality!" Aphosis snarled, its voice a guttural roar as the liquid reached its chest. "You are a fool!"

Eridin finally turned back, his face a mask of sorrowful resolve. He wasn't speaking to the serpent anymore. He was speaking to the ghost in the machine, to the boy trapped within the infernal entity.

"There is no US Aphosis, you are no Shi, you merely pirate our legacy. That you feel so strongly about our well-being is proof enough that Jao remains, that he fights even now to defy you, to defy fate... You are a parasite, leeching your way to god hood by doing the only things beasts do."

His eyes slid into slits.

"Consume, and grow fat off the back of others..."

Eridin's hand sat solemn at his side.

"Be careful staring into the abyss, Gamalow. For the abyss stares back..."

The gel rose over Jao’s face. For a fleeting second, through the distorting liquid, Eridin thought he saw a flicker of terror in those eyes—not the cold fury of the serpent, but the primal, unadulterated fear of a boy drowning in the darkness within. Then it was gone, subsumed by the impassive mask as the sedatives took hold and the system forced him back into the abyss of slumber.

"I created this monster to save us, Jao-den. Now....I will do what it takes to save you..."

He grabbed a cigarette from his lab coat, at the tip of his finger, a glimmer bloom of nestu immolated the tip. Of which he used to light it. Making his way out of the lab.

"The height of hubris to be sure....but..."

He took a long drag of it, as if he was breathing in a vow. The steel door hissed shut, sealing Jao in his silent, sterile prison. Eridin leaned against the console, the weight of a clan, a victory, and a lost boy pressing down on him. He exhaled, letting a thick cloud of smoke engulf him.

"That is what it means to be a scientist."

The halls of the mountain fortress were silent in mourning, not just for the fallen warriors of the Hawk clan, but for the living weapon locked away in its heart, a ticking bomb whose fuse was his own creator’s desperate hope. And in the darkness, the serpent coiled, patient and eternal, waiting.

--- Weeks later---

The lights were dim, a stark contrast to how Yin's personal quarters were typically kept. The candles used to light the expanse were near the end of their wax-coated ropes, their flames gasping in the still, heavy air of the stone chamber. A testament to the length of time they had been burning, the length of time his hands had been at work. Since regaining his sight—a miracle he still silently gave thanks for each dawn—he had resumed his love for the art of calligraphy. Each stroke of his quilled pen was executed by a finesse that only a seasoned practitioner could exert. He had been writing letters, poems, and strategy plans, reveling in the simple, profound ability to gaze upon the art his wife had so lovingly taught him. To see these words written, to give form to thought, was a balm to his troubled heart.

Troubled for good reason.

So many changes had sprung across the face of Edo. These lands were never peaceful, but for centuries, a certain brutal stability had held sway. The Yaarou, the Owaki—they were the pinnacle of Shinobi society. Lesser but still powerful clans made up the bedrock, and at the very bottom, trodden into the mud, were the Shi. Accursed, accused of ancient treachery, they were slaves to the whims of everyone else.

But not anymore.

After a thousand years of oppression, it was now the name of the Shi that rang out from the bells of liberated towns, whispered in the courts of trembling Daimyo. It was a time that Yin had fought for, a future his ancestors had bled for and the day had finally come. Yet nothing, not even the crisp, black ink that formed the character for 'Victory' on the parchment before him, came without a cost.

Though they had finally spearheaded the Shi clan towards the path of freedom and redemption, it was done so at the sacrifice of his grandson's humanity.

The Old Ode of the ninja code removes personality; it abolishes the shinobi of ego, molding them to become whatever tool is needed to complete the task. A shadow. A whisper. A blade in the dark.

Yet Jao... Jao had rapidly begun evolving into something far beyond anything Yin had ever considered. A cold regret, sharp as a shard of ice, lingered in his heart. The day he had encouraged Jao to leave the clan’s hidden sanctuary and explore Edo, to learn its pulse and its poisons, he never imagined the boy would return as he had. Powerful, yes—that was expected. But after reading the reports, after hearing the whispers of what he had done to the Owaki clan… a tool was meant to be wielded, not to become a force of nature unto itself.

A soft knock at the shoji screen cut through his lamentations. The paper door slid open, and from the shadows walked Yang, his son.

Yang said nothing at first. His silhouette was a study in exhaustion, the proud set of his shoulders slumped with a weight that went beyond physical fatigue. He leaned against a stone pillar, the cold rock seeming to leech the warmth from him.

“Ah, Yang… the missi—” Yin began, his voice raspy.

“Was a total shit show,” Yang cut in, his words flat, devoid of emotion. It was more terrifying than any shout.

“…”

“Jao… he completely erased the Owaki, Yin.”

A cold dread trickled down Yin’s spine. “I heard.”

“No,” Yang said, pushing himself off the pillar and taking a step into the flickering candlelight. His face was pale, his eyes hollow. “You heard words. I saw it. Not killed, not tortured… just… gone. Their fortress, their bodies, their very screams—all pulled into a vortex of absolute nothing. He unmade them.”

“His power has grown beyond what we… I never thought possible,” Yin murmured, his gaze falling to the half-finished poem on his desk.

“It’s not just his power. He was always fated to be powerful. It’s what he is now.” Yang’s voice cracked. “It’s no longer Jao.”

“Aphosis,” Yin breathed the name like a curse. “It controls him now.”

“It’s his face, Father. His eyes. But when he speaks, I can see the darkness pulling the strings beneath his glare. He looked at me, at the end… there was nothing there. No recognition. He could have killed me to see the Owaki destroyed and not even registered my death.”

Yin’s hand, steady for hours, trembled. “Right now, he's being constrained. Eridin has him sealed in the deep chambers, sedated with chakra suppressants. But that’s only delaying the inevitable. A cage will not hold.”

“Is there no way to remove Aphosis?” Yang’s question was a desperate plea, the raw cry of a father for his son.

“It is the Djynn of Darkness and Chaos,” Yin said, his voice a low thrum of ancient lore. “Yet it is also Jao. When it bonded with him, they became tethered in a way that neither can sever. To rip Aphosis out would be to shred Jao’s soul.”

“And yet it did not die when its last host, Ains, perished,” Yang pressed, his voice rising with a sliver of hope. “It moved on. There must be a way to save my son.”

Yin rose slowly, his old bones protesting. He moved to a bookshelf carved into the stone wall, pulling down a heavy, leather-bound scroll. “There may be one… but… it is a legend wrapped in a myth, spoken only in whispers.”

“But what?”

“I am not even sure whether it is a tale of truth.”

“Even if it’s but a hair of a chance,” Yang insisted, his eyes alight with a feverish intensity.

The air in Basilsk Way, deep beneath the granite teeth of the Mek Mountains, was perpetually cold and heavy with the scent of old stone. For a fleeting, fragile moment, Yang Shi allowed himself the luxury of near-silence. The low hum of the arcane-tech generators was a familiar lullaby of dread, but at least it was constant. He’d just concluded a tense strategy session with his father, Yin, the weight of their clan’s future pressing down on his shoulders like the mountain above. He leaned against a console, the cool metal a stark contrast to the heat of his anxiety, and began to form a sigh of the barest, most fragile hope.

Before he could go further, the paper doors to the Yin's dwellings slid open once more. It was Eridin. Normally a fixture of poised eccentricity, a man whose tailored lab coat was always immaculate and whose red hair was always artfully dishevelled, he now looked as if he’d been dragged through the seven hells backwards. His features were lined with an exhaustion so profound it seemed etched into his bones, and his eyes, usually dancing with intellectual fire, were dull with concern.

"We might not have the time," Eridin said, his voice a dry rasp.

Yang straightened, the nascent hope curdling in his gut. "Eridin, you look terrible."

A bitter, humorless laugh escaped Eridin's lips. "Spare me. I've been dealing with the literal damn Anti-Christ. Do you know how much sedative it takes to knock out a divine being?"

A fresh wave of paternal fear washed over Yang. "How is he? How is Jao?"

"Going from bad to worse," Eridin admitted, running a hand through his already chaotic hair. He slumped into the chair opposite Yang, a profound weariness in the motion. "I'm really starting to lament my own genius; it has really started biting me in the ass lately." He gestured vaguely towards a holographic display showing a complex, fluctuating energy signature. "As if just keeping his naten suppressed isn't difficult enough, his mind is rapidly evolving."

Eridin leaned forward, the intensity returning to his gaze. "When we—when I—bonded Jao's bone marrow with the A.I.O.N.S Core, I knew it would enhance his intellect and processing power. Such is the nature of the nanites themselves."

"But?" Yang prompted, dreading the answer.

"But I never imagined that the same would prove true for the Nether Serpent. For Aphosis," Eridin clarified, his voice dropping to a near whisper. "It is… learning. Learning how to control the nanites and seep into the techno-world."

The implication hit Yang like a physical blow. "Meaning…."

"Meaning that I've been spending half the month waging a hacker's war with an old fae, and if this keeps up, eventually it will surpass even me. It's already probing our firewalls, rewriting its own sedative protocols from the inside. It's learning to code, Yang."

"Dammit! So it's a threat even when he’s sleeping?"

"Seems to be that way." Eridin corrected. "His consciousness is free to roam the network we built to save him. And if shit hadn't already hit the fan, we must take into consideration our current standing."

Yin, his face a mask of stern control, the lines around his eyes spoke of the same sleepless nights they all endured.

"He means the Yaarou, along with the rest of Edo, no doubt have their eyes on us now," Yin stated, his voice the low rumble of shifting rock. "The energy spike from Jao’s last… episode… was more likely felt as far as the capital. No doubt beyond even then. We have scarcely left these mountains, but I wouldn't be surprised if we haven't been spotted already."

Yin’s eyes narrowed. "They know our weakness. They know our history." He turned to Yang, his expression grim. "Our family’s rise to power was not without its shadows, my son. We made pacts and broke them. The power Jao wields, the curse he bears, is the price of our ambition."

He walked towards a large, ornate scroll case that stood in the corner of the room, a relic from a bygone era. "You asked how we might save him. Perhaps the answer lies not in Eridin’s technology, but in the truth of our past."

He unrolled the ancient parchment. The script was archaic, the ink faded. "It is believed that after Aphosis was scorned and betrayed by Tero, our founder, he was cursed. Aphosis bonded his soul with the flesh of Tero, thus creating the Dankestu, eyes that would consume the souls of whoever gazed into them."

"A story we all know," Yang said, his attention torn between his father's history lesson and the light display of his resting child.

"But you don't know all of it," Yin countered, his voice resonating with newfound urgency. "Yet then… why was it that the Dankestu did not first awaken until generations later? And even what's more, why did the first Endless iteration of the cursed eyes not appear until Ains himself, thousands of years after the curse was first sired?"

Eridin looked up from his console, his own curiosity piqued despite the immediate danger. The intruder had stopped just outside the archive doors.

Yin traced a faded symbol on the scroll, a spiral of light entwined with a serpent of shadow. "It is believed that Aphosis is but a single half of a whole. No... that's far too simple. More like a whole of a greater whole. That while he was sired darkness and chaos, another force, capable of balancing and suppressing him, exists." His gaze met Yang's, a flicker of something akin to desperate hope in their depths. "It was theorized that this being of light also entered Tero and suppressed the curse within him. For centuries, it held Aphosis dormant. But somewhere, somehow, that being was overshadowed, and the curse took over."

The pieces clicked into place in Yang’s mind, a terrifying and beautiful mosaic of cosmic duality trapped within his own bloodline. "We… must find out who… or what that power is," he breathed. "It may be Jao's only ho-"

"Code Red. Code Red. Perimeter breach confirmed."

His words were cut short by a shrill, piercing alarm. Red lights strobed across the stone walls, painting their strained faces in a bloody light. A synthesized voice, devoid of emotion, echoed through the chamber.

The automated, synthesized voice echoed through the stone corridors of the Shi clan's stronghold, each word a chilling herald of doom. The lone candle, its flickering light a beacon against the encroaching dark, responded to the sudden, unnatural gust with frantic violence. A peculiar aroma, the metallic tang of old blood mingling with the sharp, sterile scent of chemicals, permeated the air.

Yang and Yin, their faces etched with a deep, paternal concern that moments before had been veiled by scholarly contemplation, were already moving. The quiet dignity of scholars was a discarded garment; in its place stood seasoned warriors, their eyes, narrowed and sharp. Their bodies, taut and ready, coiled with a deadly intent that belied their years.

"Report!" Yin commanded, his voice, usually a calm resonance, now a sharp blade cutting through the oppressive stillness. He peered into the inky blackness of the main corridor, the epicenter of the intrusion.

Static crackled over the comms, a desperate prelude to the horror that had befallen their scouts. Then, a choked gasp, ragged and terrified. "Mist… everywhere… red mist… I see… I see them crawling on the walls… gods, the pain… It’s not real… it’s—" The transmission dissolved into a wet, guttural sound, a final, damning silence.

From the main corridor, it came. Not with a thunderous assault, but with a silent, inexorable creep. A thick, crimson vapor, like atomized blood, rolled along the floor. It didn’t dissipate; it clung to the ancient stone, coiling in ethereal tendrils as if imbued with a malevolent life of its own.

A squad of Shi guards, their naten burning with nestu, stood ready at the far end of the hall. They tried to cover their faces, unaware that the red of the mist was not the threat; it was the confirmation that one was already under the effects of its call. It was insidious, a phantom enemy that didn't break defenses but flowed around and through them, corrupting them from within.

The first guard let out a strangled scream. His stance faltered, his hands flying to his face as if to tear away imaginary tormentors. "Get them off me! The spiders! They're crawling on me!" His eyes, wide with unreasoning terror, darted wildly. There was nothing there but the deepening crimson haze.

Another guard cried out, his gaze fixed on his comrades, his voice laced with an unhinged paranoia. "Traitors! I hear you!" In his madness, he swung his nestu-infused slash, the blade carving a path through the air and, with a sickening thud, slicing down the man beside him. The fallen warrior clutched his stomach, his face contorted in agony, convinced he had been disemboweled, while the crimson mist offered no wound.

From within the roiling crimson, figures began to move. They were specters, their dark grey shinobi-shōzoku blending seamlessly with the sanguine haze.

One guard, convinced a blade was already lodged in his spine, arched his back in excruciating agony, exposing his throat. A shadow detached itself from the mist, a tanto flashed with blinding speed, and the phantom pain became a horrifying reality. He fell without a sound, his terror silenced forever. Another, swinging his weapon wildly at the whispering ghosts that only he could perceive, left himself utterly vulnerable. A shinobi flowed past him, impossibly silent, a thin, near-invisible wire wrapping around his neck. A sharp, decisive tug, a sickening snap, and the whispers in the warrior's head fell silent, replaced by an eternal quiet.

"The ventilation system, it's been compromised..." Yang grunted, his voice strained. He placed his mask on, as did Yin, before they hurried towards the others.

"Chikage," Yin stated, his voice low and dangerous. "This mist, it is theirs."

The corridor ahead was choked with a roiling crimson mist, thick and opaque as a shroud. It billowed back as they approached, revealing the carnage. Bodies of their clansmen, elite guards, were twisted in unnatural positions, their throats slit with surgical precision. The floor was slick with real blood mixing with the phantom vapor. And from its depths, a figure walked forth.

He was a young man, perhaps but a few years older than Jao, with brown skin and a stark streak in his hair the color of bone. He wore the same grey attire as his fallen kin, but his was finer, embroidered with silver thread that seemed to drink the candlelight. His movements were a study in refined grace, each step silent, deliberate. In one hand, he held a single, perfectly blooming red spider lily between his fingers. He stopped just beyond the effective range of their techniques, his amber eyes holding an unnerving, placid madness.

“Lord Yin. Lord Yang,” the voice was smooth as polished jade, yet carried a dissonant, chilling overtone, like a beautiful bell cracked down the middle. “So this is what the fabled Shi clan has been reduced to? Mere guttersnipes guarding a gilded cage?”

He raised his free hand, and the mist obeyed him. It coiled and condensed, forming a dozen writhing ribbons of pure crimson vapor that hissed silently in the air around him, each one twisting like a serpent poised to strike. “My grandmother always spoke of the Shi as a fortress of unyielding will. Living incarnations of terror and fear. I see now she was mistaken.” He took a delicate sniff of the flower, a gesture of profound arrogance. “She saw a fortress. I see a tomb.”

Yang stepped forward, his naten—his life force—flaring to life like a blue inferno. “The Chikage. Sewer rats finally crawling from obscurity to die in the light.”

A smile graced the young man’s lips, a subtle, cruel curving. “Obscurity has been our crucible, Lord Yang. I am Moroha, Moroha Chikage, heir to the Blood Shadow clan. And while the Shi clamored beneath the mountains, we refined our art. We perfected it.” He gestured with the spider lily, and a tendril of mist shot forward. For a split second, it solidified into a razor-sharp blade of hardened vapor, glinting red. Yang barely parried it with a naten-infused kunai, the impact sending a shower of sparks into the bloody air.

"If I were you, I would be swift to get to the point," Yang snarled, his patience worn thin.

“The Bingo Book offers a handsome sum,” Moroha continued, his tone conversational, as if discussing the price of rice. “The Shi Clan, exterminated. The Serpent's Heir, one Jao-Den Denkoushi, to be delivered alive. A simple transaction. Your lives are merely the cost of business.”

Yin’s eyes, chips of obsidian, narrowed. His hand glazes over with frost in an instant. “You think you can just walk in here and claim my grandson?”

“Walk?” Moroha’s smile widened, revealing a hint of unhinged glee. “Lord Yin, I have been ‘in here’ for the last ten minutes.”

That was all the prompting Yang needed. He exploded forward, a blur of motion, his blade a streak of silver aimed for Moroha’s jugular. Yet in the instant before impact, Moroha’s visage dissolved, exploding into a dense cloud of crimson mist.

It wasn't an attack, but a sensory deluge. The coppery scent became overpowering, a physical force that gagged them. Phantom whispers erupted in their ears—Jao screaming for help from a distant room, the dying words of their fallen comrades, the spectral weeping of their own wives. The stone floor beneath their feet felt like it was swarming with biting insects, a horrifying, tactile illusion.

Moroha's masterpiece, the Kurenai Jōki—the Crimson Vapor—was not merely a poison; it was a weaponized nightmare. It didn't attack the body; it soiled the mind, twisting a warrior's greatest asset—his perception—into his most profound and deadly enemy. The zero-visibility was nigh-absolute, and worse, the mist absorbed and dissipated heat, rendering even the Shi clan's advanced thermal imaging utterly useless. They were blind, deaf to reason, and tormented by their own senses.

“Your rage makes you predictable,” the Chikage heir whispered, his voice seeming to come from inside Yang’s own skull.

Yang roared and charged again, a whirlwind of motion. But he was fighting shadows. Moroha was everywhere and nowhere. A feint to the left, a phantom blade sliding past his ear. The sharp sting of a senbon in his shoulder, thrown from an angle that defied physics. He saw Moroha standing before him, ran him through with a blade of pure heat, only for the image to dissolve into mist. The real Moroha appeared behind him, his tanto tracing a shallow, cold line across Yang’s back.

"How do you like my Kurenai Jōki?" Moroha’s voice was a silken taunt in the chaos. "Quite the power, isn't it? To weave the very moisture in the air, to augment and corrupt the perception of reality… it is quite something."

Yin was more controlled. He closed his eyes, shutting out the horrifying illusions that gnawed at him, and focused solely on the subtle language of the world his eyes could no longer trust. For Yin was a man accustomed to the darkness, and could prove even deadlier without it. He felt the minute shift in air pressure, the faint vibration of a footstep on stone. He spun, his movements economical and precise, and launched a volley of ice bullets—small, compressed shards of ice—at a precise location in the mist.

A grunt of surprise, and Moroha materialized, a shallow cut bleeding on his cheek. The placid mask was gone, replaced by an expression of delighted insanity. “Ah! There it is! The will of the Shi! The infamous Sunless perception that can see through deceit!”

He made a new set of seals, his fingers a blur of impossible speed. “But trauma is a rot that is ever present, whether you know it or not.”

The Kurenai Jōki around them shifted, not just in shape, but in substance. It swirled and took on the form of the chamber they stood in, but subtly, terribly wrong. The walls seemed to sweat blood. From a darkened corner, a new figure emerged from the mist—a woman with Yang’s features and Jao’s eyes.

Yang’s dead wife.

“My love… why did you leave me?” They turned me into a monster, and now...you've let our only child become one as well. The apparition whispered, its voice a perfect echo of his guilt and regrets.

That broke him. A raw, guttural scream of anguish tore from Yang's throat. It was the final straw. Yin, seeing his son’s will begin to fracture, knew they had no other choice.

"Yang, do not let yourself be swayed by his madness."

A forboding presence began to fill the room as Yin's will sharpened.

"Let your will be like the venom of a serpent, all-consuming, all devouring."

The Mantra of the Shi clan, a dogma he lived and breathed now grounded in Yang.

"Let your eyes strike terror in the hearts of your enemies."

Yang compelted

“!!!”

Yin's voice broke the spell.

Their heads snapped up in unison. A primal roar of fury and anguish tore from Yang’s throat. Yin’s face was a mask of cold fury. In perfect unison, they looked at Moroha, and their eyes changed. Their pupils dilated into bottomless black pits, and their irises began to glow, Yang’s with the heat of a dying star, Yin’s with the cold light of the void. This was the Dankestu, the Shi’s most feared ability—a gaze that could seize and consume the very soul of its target. Through the crimson vapor, their glares were monstrous, predatory beacons that promised not death, but oblivion.

Yet, though terrifying it may be, their ocular ability faltered. The Kurenai Jōki was far more than a simple hallucinogen; it actively corrupted the neural pathways for sight, sound, and smell. It wove a dense, malevolent shroud around the very fabric of perception. The Dankestu needed a clear, true target to lock onto, a soul to claim. But in this world of Moroha’s making, there was no truth. Their soul-devouring gaze passed through phantom images, finding no purchase; their ultimate weapon was rendered impotent.

“So that it, the Serpent's Glare, fearsome indeed.” Moroha’s voice echoed, laced with mocking pity.

Yin gritted his teeth, the cold aura around him intensifying. “So it is true, the mist is capable of interfering with our Dojustu. I can see why Ains once sided with your ancestors...” Yin inhaled a sharp but fierce breath, lifting his hand, clad in the frost sinew of his nestu, and caved it into the floor. “But we are far more than the sum of our parts!”

A wave of intense cold radiated from the impact point, flash-freezing the mist in a five-meter radius around them. The crimson vapor turned to delicate, falling crystals of red ice. For a moment, they had a pocket of clarity.

Yang understood instantly. He focused his Sinder Style, not to attack, but to perceive. The mist was capable of absorbing and dispersing heat, which normally would make Yang's nestu ineffective. But Yin's senses were honed with otherworldly proficiency. His mind was a fortress of will and integrity. By using his ice to guide Yang's blaze, they would find the means to tear through Moroha's veil.

“Ephemeral Art!” Yin roared.

It was a deadly dance of thermal extremes. Yin became the anchor, his Rhyme Style painting the battlefield with zones of absolute zero. He would stomp his foot, and the floor would fracture with frost, sending shards of sub-zero stone shrapnel flying in all directions. Yang, moving with blinding speed, used these cold zones as a map. He unleashed lances of searing heat, not at where he saw Moroha, but where the thermal equilibrium was disrupted.

"Dance of Frost and Flame"

Yang exclaimed

A blast of fire vaporized an illusion. A wave of frost trapped a phantom blade. For the first time, Moroha was on the defensive, his graceful movements becoming hurried dodges. That mistake could reveal his location.

It was all the opening they needed. In that instant, Yang dropped his blades, his fist blazing with smoldering heat. Adjacent to him, Yin's fist radiated an aura of absolute zero.

"Combo Skill:Piercing Dragon;Blazing Moth!"

Yin was a blur, his hand a spear of solid ice. Yang was a comet, his nestu streak of incandescent light. They struck as one, a perfect fusion of fire and ice, impaling the figure from both front and back. Certain, for the first time in this fray, of their victory.

There was a moment of triumphant silence.

But the body didn't dissolve. It slumped, a wet, heavy sound echoing in the hall. As the last of the mist cleared, the features of their foe rippled, the bone-white streak in his hair fading, the proud, mad face melting away.

Lying impaled between them was not Moroha Chikage. It was Anna, Eridin’s assistant. Her mouth opened, but only a choked gurgle of blood and red mist came out. She collapsed, the light fading from her eyes.

Horror, cold and absolute, washed over them. Yin stared at the crumpled form, his mind racing, connecting the impossible dots. The initial alarm… the defense systems failing one by one from the inside… Anna had been in the control room.

Yang's face ran pale from the shock. The warm crimson scythe on his fist crumbled into dust. He stumbled back, steadying himself against a pillar, his breath catching in his throat.

"This...is beyond anything I've ever known a Chikage capable of," Yang rasped, his voice raw.

"He was controlling her with his mist," Yin deduced, his own voice tight with grim understanding. "Altered her appearance through Ephemeral Arts....to what end?"

A horrifying clarity dawned on Yin's face. “He was never fighting us,” he whispered, the realization a punch to the gut. “He was stalling.”

The true Moroha was somewhere else. Yang looked at the gentle face of the woman they had just slain, a wave of sickness churning in his stomach. He knelt, softly laying her head upon the cold ground, giving a light nod to Yin. They had to move; they would have to mourn her and ponder their karma at a later time.

"Yin, Yang, the power grid went down. Someone dis-"

Just as they were turning to leave, Eridin caught up with them. The schematics of the base glowed from a holo-projector on his wrist, his face a mask of urgency. Then his eyes fell upon the body on the floor, and the color seemed to drain from the holographic light and his face alike.

"Gods no..."

He rushed to her side, falling to his knees. He cupped her still-warm head in his trembling hand, his brilliant mind utterly shattered.

"An-Anna, please...no...not you." His voice was a broken, desolate whisper.

"Forgive us, Eridin," Yin said, his tone heavy as granite. He placed a comforting hand on Eridin's back, a gesture that felt woefully inadequate. "We...we must press forward. The Chikage are still here. They are after Jao."

Yin took a deep, steadying breath, then nodded to a shell-shocked Yang. They left Eridin to his grief, their footsteps echoing with a new, desperate haste as they raced to the heart of the mountain.
-----------------------------------------------------------------------------------------------------------------------------------------------------------

Deep within that heart, in the sterile white light of the containment room, Moroha Chikage stood serene. He was immaculate, his robes undisturbed. He gently placed a red spider lily on a control console, its crimson petals a stark, bloody contrast to the gleaming steel. Before him was a massive, cylindrical tube filled with translucent gel, intricate seals glowing with faint blue light on its surface. Suspended within, peaceful and unaware, was Jao.

Moroha reached out, his fine-boned fingers pressing against the cool glass, right over the boy’s closed eyes. A thin, self-satisfied smile touched his lips.

“The Serpent’s Heir,” he murmured, his voice a soft caress of victory. “Guess you're not a fairy tale after all. Grandmother will be so pleased.”

As his fingertips rested on the glass, one of Jao’s eyes snapped open.

It wasn't the eye of a boy. The iris was a venomous violet, the pupil a vertical, reptilian slit. It regarded Moroha not with the fear of a captive child, but with an ancient, terrifying, and all-too-familiar darkness. Aphosis was awake.
