Rhodes Island Medical Wing, 0600 Hours
The first Possessed were brought in under heavy guard eight hours into the cleaning operations. A family of five, their transformation so complete that only the butcher who had reported them could identify who they used to be before Mephisto's Arts had stripped away everything that made them human.
Nearl supervised the transport personally, her knight's bearing never wavering despite the horror of what she was escorting. The Kuranta operator had found them in a residential apartment after the butcher, a heavyset Forte man whose hands still smelled of meat and smoke, had approached her during her sector sweep.
"My neighbors."
He had said, his voice carrying the tremor of someone who had seen something fundamentally wrong.
"They've been acting strange for three days now. Don't respond when you call them. Just stand in their apartment staring at nothing. I thought maybe they were sick, tried to bring them food, but when I opened the door..."
He had trailed off, unable to articulate what he had witnessed. Nearl had investigated immediately, finding the family exactly as described. Father, mother, two children, and an elderly grandmother. All five standing motionless in the center of their living space, their eyes glazed with the particular emptiness that came from having consciousness ripped away and replaced with dormant programming.
Mephisto's Possessed. The first confirmed cases out of an estimated fifty thousand hidden throughout Lungmen.
The medical wing had been prepared for this moment. Isolation chambers with reinforced walls, scanning equipment calibrated to detect the specific biological signatures Kal'tsit's research had identified, and security personnel positioned to respond if the Possessed activated unexpectedly.
The Doctor stood in the observation room overlooking the isolation chambers, their hooded figure motionless as medical staff conducted examinations. Kal'tsit worked alongside her team with clinical precision, documenting every detail of the transformation while searching for vulnerabilities that might lead to reversal.
Beside the Doctor, the butcher watched through the observation window, his expression mixing horror and guilt.
"I should have reported it sooner. Should have known something was seriously wrong instead of just thinking they were sick."
"You reported it as soon as you understood the severity."
The Doctor's tone carried reassurance without condescension.
"That's what matters. Because of your vigilance, we have our first subjects to study and potentially cure."
"Can you cure them? Can you bring them back from whatever Reunion did to them?"
"We're going to try."
Kal'tsit's voice came through the observation room's speakers, her clinical assessment cutting through emotional weight with facts.
"The transformation is extensive but not necessarily permanent. Mephisto's Arts work by overwriting neural pathways and suppressing higher brain functions. The original consciousness still exists, just buried beneath layers of external control."
She gestured to the scans displaying on monitors around the isolation chamber.
"The challenge is removing that control without damaging the underlying personality. It's similar to extracting a parasite that's integrated itself into the host's nervous system. Possible, but requiring extreme precision."
The Doctor pulled out a small case from inside their coat, the container holding an object that seemed to distort light around it. The Holy Grail, compact enough to be portable but radiating power that made the air itself feel heavier.
"I have a method in mind. But it requires accelerating research that would normally take months into a timeframe measured in hours."
They looked at Kal'tsit through the observation window.
"Can you develop a theoretical framework for the cure? Something that outlines the approach even if the actual implementation would require extensive testing?"
"I can have preliminary research ready within two hours. But preliminary research isn't the same as proven treatment. Using the Grail to accelerate unfinished work creates risk of unforeseen complications."
"The alternative is accepting that we might not develop a cure before Reunion's assault activates the Possessed. That risk is unacceptable."
The Doctor turned to the butcher.
"Thank you for your report. Your neighbors are in the best hands available, and we'll do everything possible to restore them. Please provide your contact information to the administrative staff. We'll notify you of any developments."
The man nodded, relief and continued worry mixing across his features. He left the observation room escorted by a junior operator, leaving the Doctor alone with the Grail and the weight of decisions that would affect thousands of lives.
Kal'tsit's research proceeded with her characteristic thoroughness. She mapped neural pathways, documented Arts signatures, identified the specific mechanisms through which Mephisto's control manifested. The work was complex, requiring expertise that few medical professionals in Terra possessed, but Kal'tsit was among the best for exactly this kind of challenge.
Two hours later, she transmitted her preliminary findings to the Doctor's terminal. Theoretical framework for reversal, potential pharmaceutical interventions, Arts based disruption techniques. Everything she could develop in the limited time available, organized with the clinical precision that defined her work.
The Doctor reviewed the research in their office, the Holy Grail resting on the desk before them. The artifact pulsed with subtle radiance, responsive to proximity of someone considering its use.
"I wish for the cure to Mephisto's Possessed transformation."
They spoke carefully, ensuring the wording was precise.
"Based on Kal'tsit's research framework, accelerate the development process until we have a proven treatment that can be safely administered to restore victims without causing permanent damage."
The Grail responded, golden light intensifying as it processed the request. Reality bent around the artifact, time itself becoming negotiable within a localized sphere. The Doctor felt knowledge flooding into their mind, research that should have taken months compressed into moments as the Grail granted understanding born from accelerated experience.
Pharmaceutical compounds that would disrupt Mephisto's Arts without harming the host. Specific Arts techniques that could be applied to sever external control. Step by step protocols for treatment that accounted for individual variation and potential complications. Everything needed to restore the Possessed, delivered complete and proven through the Grail's reality warping authority.
The Doctor gasped as the information integration completed, their mind struggling to process months of compressed research experience. When clarity returned, they immediately began documenting the cure, translating the Grail granted knowledge into formats that medical staff could implement.
Within an hour, treatment protocols were distributed to Rhodes Island's medical teams and LGD's healthcare divisions. The cure existed, proven and ready for deployment against every Possessed they could locate before Reunion's assault activated the dormant army.
The family of five became the first test cases. Medical staff administered the pharmaceutical compounds while Arts specialists applied the disruption techniques exactly as the protocols specified. The process took three hours per patient, requiring careful monitoring to ensure the treatment was progressing correctly.
When the father opened his eyes and spoke his own name for the first time in days, recognition flooding back as Mephisto's control dissolved, the observation room erupted in restrained celebration. Success. The cure worked.
Four more treatments followed with similar results. By evening, all five family members had been restored, their consciousness returned and their memories of the transformation mercifully vague. They would require ongoing medical observation and psychological support, but they were themselves again. Saved from the fate Mephisto had intended for them.
The Doctor stood in the observation room as the family was reunited with the butcher who had reported them, watching the tearful embraces with satisfaction that transcended tactical victory.
"Fifty thousand Possessed."
They said quietly to Kal'tsit, who had joined them after completing the final treatment.
"We have forty three days to locate and cure fifty thousand people using a treatment that takes three hours per patient. The mathematics are barely feasible even with every medical resource in Lungmen working continuously."
"Then we make it feasible. We train additional medical personnel, we establish treatment centers throughout the city, we coordinate with LGD to maximize efficiency."
Kal'tsit's tone carried absolute determination.
"You created the cure. Now we implement it on the scale necessary to prevent catastrophe."
"Agreed. Begin organizing the expanded medical operations immediately. I'll coordinate with Ch'en about establishing treatment facilities in LGD controlled districts."
They turned away from the observation window, mind already processing logistics and resource allocation.
The first five were saved. Forty nine thousand nine hundred ninety five remained hidden throughout Lungmen, waiting to be found before Reunion could activate them.
The race had truly begun.
Lungmen Underground, Abandoned Factory District
I moved through the underground facility with enhanced perception tracking everything simultaneously. The space had been a factory once, some kind of manufacturing operation that processed materials whose purpose I couldn't identify from the decaying equipment. Now it was abandoned, claimed by darkness and the particular quiet that came from places humans had surrendered to time.
My sector assignment had led me here following reports of unusual activity near the old industrial areas. People disappearing into underground access points, sounds that suggested habitation in spaces that should be empty. The kind of intelligence that might indicate Possessed being hidden in locations nobody would think to search.
The Mystic Eyes showed me everything in perfect clarity despite the absence of light. Death lines traced across walls and support pillars, machinery and debris, showing me the fundamental mortality of every object. The harmonized version made the perception effortless, no strain or pressure from maintaining constant awareness.
Movement ahead, multiple contacts approaching with coordination that suggested combat training. Not Possessed then, their movements were too purposeful. Reunion operatives probably, guards assigned to protect whatever was hidden in these depths.
I could have avoided them easily. My assassination training made stealth trivial, and the darkness provided perfect cover for someone who could see death lines regardless of illumination. But avoidance wouldn't provide the combat experience I needed, wouldn't test how my Noble Phantasms integrated under actual fighting conditions.
The training sessions with Surtr had been valuable but controlled. Real combat was chaotic, unpredictable, forcing adaptation in ways that sparring never quite replicated. These operatives represented opportunity to train against opponents who would genuinely try to kill me.
I summoned Kanshou and Bakuya, the married swords materializing with familiar weight. The twin blades felt right in my hands, balanced perfectly for dual wielding style that Shiki's muscle memory guided naturally. I activated Knight of Owner simultaneously, the ability allowing me to treat the factory's environment as extension of my arsenal.
The Eightfold Blessing manifested around me, eight mirrors floating in formation that created tactical options beyond simple offense. I configured four mirrors for barrier deployment, creating layered protection that would absorb initial attacks. The remaining four I positioned for Arts amplification, ready to enhance whatever capabilities I needed during the engagement.
The Reunion operatives emerged into the chamber where I waited, five soldiers moving with practiced coordination. They spotted me immediately, weapons raising as tactical assessment registered threat level. To their credit, they didn't waste time with demands or questions. They simply attacked with professional efficiency that suggested extensive combat experience.
The first operative launched Arts based projectile, compressed energy that would have serious consequences on impact. I deflected it with one of the barrier mirrors, the attack splashing harmlessly against reflective surface while I closed distance with the swordsmen.
Kanshou and Bakuya moved in the flowing patterns their legend demanded, each blade complementing the other through attraction and repulsion that created attack angles impossible with normal weapons. I engaged two operatives simultaneously, the married swords finding gaps in their defense through combinations that overwhelmed individual blocking attempts.
Knight of Owner activated on the factory floor itself, treating the reinforced metal as weapon I could manipulate with master level skill. My Mystic Eyes showed me the death lines in the floor's structure, points where strikes would sever integrity and create tactical advantages.
I struck specific locations with my tanto between sword combinations, the blade finding death lines with surgical precision. Sections of floor collapsed strategically, creating obstacles that disrupted the operatives' coordination while leaving my own movement unimpaired.
The remaining three operatives adapted quickly, using Arts to create platforms that negated my environmental manipulation. Fire manifested, ice formed barriers, wind created pressure zones that forced repositioning. They were good, better than the Reunion soldiers I had faced at Sal Viento. Elite operatives rather than standard troops.
Perfect for testing my limits.
I threw Kanshou toward the fire Arts user, the blade curving through an arc that bypassed their defensive positioning. They blocked with Arts barrier, flames intercepting the sword before it could connect. But that was anticipated. Bakuya followed immediately, the twin blade's attraction to its partner creating trajectory that curved around the barrier to strike from an unexpected angle.
The fire operative went down with Bakuya embedded in their shoulder, the injury severe enough to remove them from combat. I recalled both swords as I engaged the ice specialist, married blades returning to my hands while I ducked under frozen projectiles.
The Eightfold Blessing's amplification mirrors enhanced my speed, Arts boost making movements faster than normal limits allowed. I closed distance before the ice operative could adjust their targeting, tanto finding the death line across their weapon. The blade severed the fundamental existence of their catalyst, the item dissolving into nothing as its mortality was ended.
Without their weapon, the ice specialist was vulnerable. I struck non lethally, tanto finding pressure points that would incapacitate without killing. They collapsed unconscious, removed from the fight but alive.
The wind Arts user and the two swordsmen coordinated their assault, attacking from three directions simultaneously in pattern designed to overwhelm individual defense. Against normal opponents it would have worked, forcing choices between blocking attacks or accepting damage.
But I had Rho Aias.
The seven layered shield manifested between me and the wind operative's attack, bronze petals absorbing their Arts completely. The first petal cracked under sustained pressure but held, protective authority denying the wind's cutting force.
That left me free to engage the swordsmen with Kanshou and Bakuya, the married blades meeting their weapons in exchanges that filled the chamber with metallic impact sounds. They were skilled, their techniques suggesting formal training rather than self taught combat. They worked together with coordination that spoke to extensive partnership.
I matched their coordination with superior individual skill, each of my strikes finding optimal positions through combination of Mystic Eyes perception and Shiki's assassination expertise. Kanshou deflected one operative's blade while Bakuya thrust toward the gap created, forcing defensive response that opened vulnerability for the next combination.
The wind operative saw their teammates struggling and changed tactics, redirecting their Arts toward environmental control. Wind pressure increased dramatically, creating turbulence that made maintaining balance difficult while fighting skilled swordsmen.
Clever adaptation. Use environmental effects to degrade my combat effectiveness without risking friendly fire on their own people.
I responded by deploying the remaining Eightfold Blessing mirrors in barrier configuration, linking all eight to create dome that protected me from wind pressure while simultaneously containing the swordsmen inside with me. The mirrors' barrier was one way, allowing me to attack out while preventing wind from affecting the interior.
Inside the dome, isolated from their support, the two swordsmen's coordination began showing cracks. They were trained for team fighting, their techniques designed to work with backup rather than completely alone against superior opponent.
I pressed the advantage, Kanshou and Bakuya moving faster as I stopped holding back. The married swords traced death lines I identified, each strike targeting points where blocking would create greater vulnerabilities. The swordsmen defended desperately but their skills were inadequate for the combination of supernatural perception and legendary weapons.
Within thirty seconds, both were disarmed and incapacitated. I had deliberately avoided lethal strikes, using the flat of the blades and precise impacts to render them unconscious rather than dead.
The wind operative was alone now, their teammates defeated and their Arts still unable to penetrate the mirror barrier. They made the intelligent choice, retreating through the underground facility's passages at speeds their wind Arts enhanced.
I let them go. Five combatants, four captured or incapacitated, one escaped. Good training results without unnecessary killing.
I dismissed the Noble Phantasms and assessed myself for injuries. Minor bruises from impacts I hadn't perfectly avoided, slight exhaustion from maintaining multiple abilities simultaneously, but nothing serious. The combat had lasted maybe three minutes total, though it felt longer while actively engaged.
My communicator chimed with priority alert, the specific tone indicating urgent message from command. I activated it while binding the unconscious operatives with materials scavenged from the factory.
"All operators, priority alert."
The Doctor's voice carried across the channel with controlled urgency.
"Surtr has encountered Mephisto and Faust in the western industrial sectors. This is days ahead of system predictions. All available combat personnel are to converge on her position immediately. LGD is being notified simultaneously."
I felt my blood run cold. Mephisto and Faust, found already when we had expected weeks of searching. Either incredibly fortunate coincidence or something had changed to accelerate the timeline.
"Surtr, do not engage alone. Maintain visual contact and wait for support. Mephisto's capabilities make solo combat extremely dangerous."
"Too late for that."
Surtr's voice came through, carrying the particular intensity she got during serious fights.
"They spotted me, I spotted them, and neither side is backing down. I'm engaging to prevent their escape. Send support quickly if you want prisoners instead of corpses."
The communication cut off, replaced by sounds that suggested immediate combat. Flames roaring, structures collapsing, the chaos of Surtr fighting at full power.
I was already moving, my enhanced speed carrying me toward the surface and the coordinates the Doctor had transmitted. Western industrial sectors, approximately fifteen minutes away at maximum speed.
The unconscious Reunion operatives would have to wait. Mephisto was the priority, the lynchpin of the entire catastrophic event we were trying to prevent.
If we could capture or eliminate him now, the threat of fifty thousand Possessed being activated would effectively end.
LGD Headquarters, Ch'en's Office
The priority alert reached Ch'en while she was reviewing patrol schedules, the notification's specific tone making her abandon paperwork immediately. She grabbed her sword from where it rested against her desk, the weapon she had wielded through countless operations, its weight familiar and reassuring.
Hoshiguma was through the door before Ch'en could call her, the oni woman's shield already secured and her expression carrying combat readiness that came from years of partnership. They didn't need to discuss, didn't waste time with questions. The priority alert's content was self explanatory.
Mephisto and Faust located. Surtr engaging. All combat personnel converging.
This was the opportunity they had been preparing for, the chance to eliminate Reunion's biological warfare specialist before he could deploy his Possessed army.
"Assemble tactical response teams one through four."
Ch'en's orders were clipped, efficient.
"Full combat loadout, heavy weapons authorized, non lethal options secondary priority. We move in three minutes."
LGD headquarters erupted into organized chaos as experienced officers responded to the alert. Weapons were distributed, vehicles prepared, tactical teams assembling with the speed that came from extensive drill practice.
Ch'en strapped her sword properly, the familiar ritual helping focus her mind on what was coming. Mephisto was extremely dangerous, his Arts capable of turning any confrontation into nightmare scenario where your own allies could become enemies. Capturing him would require overwhelming force deployed with absolute precision.
"Hoshiguma, you're with me in the lead vehicle. We're establishing perimeter control and preventing escape routes. Secondary teams will handle containment once we've secured the area."
"Understood. What about Rhodes Island? Are we coordinating entry or operating independently?"
"Doctor said their operators are converging. We coordinate but maintain separate command. LGD leads the assault as agreed, Rhodes Island provides support and specialized capabilities."
Ch'en checked her communicator one final time, confirming she had direct line to the Doctor and access to tactical updates from operators already en route.
"Three minutes. Let's move."
Western Industrial Sectors, Combat Zone
Surtr stood in the center of devastation her flames had created, staff blazing with heat that made the air ripple. Before her, Mephisto cowered behind Faust's protective positioning, the young boy's usual manic energy replaced by genuine fear now that he faced someone whose power exceeded his ability to comprehend.
Faust held his crossbow ready, the weapon that had never failed to protect Mephisto from threats. But even he seemed uncertain about their chances against Surtr, his body language suggesting he understood they were outmatched catastrophically.
"You're the one who makes the Possessed."
Surtr's voice carried across the space between them, flames intensifying with each word.
"You're the reason we've been searching Lungmen for victims of biological warfare. Fifty thousand people you transformed, fifty thousand lives you stole."
"They're not stolen!"
Mephisto's voice cracked with defensive hysteria.
"They're saved! Saved from a world that hates them, saved from suffering, given purpose as part of something greater than their miserable individual existence!"
"You're insane. But that's not my concern. My concern is making sure you never transform anyone again."
Surtr's staff erupted with Laevatain's full manifestation, flames taking form as conceptual destruction that would reduce anything they touched to ash.
Faust's crossbow fired, the bolt moving with speed that suggested Arts enhancement. But Surtr simply burned it out of the air, her flames consuming the projectile before it could reach her.
"That won't work. Nothing you have will work. I'm going to burn you both, and then I'm going to burn every Possessed you created until there's nothing left of your biological warfare except ash and bad memories."
She advanced, each step leaving scorched footprints, her presence alone enough to ignite materials that got too close.
Mephisto was screaming now, his Arts activating in desperate self defense. The Possessed that had been hidden nearby responded to his call, shambling figures emerging from buildings and underground access points. Dozens of them, civilians whose consciousness had been stripped away, now commanded to attack the threat their master feared.
Surtr showed no hesitation. Her flames washed over the approaching Possessed, ending their tortured existence with mercy that came through overwhelming force. They fell as ash, their suffering concluded through fire that didn't discriminate between victim and perpetrator.
"Send more. Send all of them. I'll burn every single one while you watch, and then I'll burn you last so you can understand what failure feels like."
The arrogance in her voice was absolute, backed by power that made the threat completely credible.
Faust fired again, this time targeting the ground around Surtr to create obstacles or distraction. The bolts embedded in pavement and detonated, Arts charged explosions that would have devastated normal opponents.
Surtr walked through them without slowing, flames absorbing the explosive force and converting it to fuel for her own Arts. She was a walking apocalypse, unstoppable through conventional methods, requiring either overwhelming coordinated assault or retreat as the only viable options.
And Mephisto was too terrified to retreat, too committed to his delusions to recognize when escape was the intelligent choice.
The situation was escalating toward lethal conclusion when support began arriving. Rhodes Island operators converging from multiple directions, LGD tactical teams establishing perimeter, the combat zone transforming from solo engagement to coordinated operation.
The hunt for Mephisto had reached its critical moment, days ahead of predictions but with all the key players assembled.
Whatever happened next would determine whether Lungmen's catastrophic threat ended tonight or escalated into something worse.
