"Academic databases, institutional hiring records, and retroactive edits to published research," Jihoon said. He stood at the kitchen table with his left hand braced on the surface and his right hand — the compression sleeve's hand, the hand that couldn't grip — resting at his side. The map of Korea was gone, replaced by Yoon's handwritten pages and a legal pad where the swordsman had been building a list in the tight, angular script that military service produced. "That's three separate systems. Three different institutional architectures. Each with its own access controls, audit logs, and administrative oversight."
Yeji sat across from him. Morning tea untouched. The fifty-two-percent migraine had settled into a background rhythm — present but manageable, the chronic companion of a channel operating below half capacity.
"A single person couldn't do it alone," Jihoon continued. "Editing published papers requires access to the journal's archival system. That's academic infrastructure — universities, publishers, digital repositories. Modifying the Cheonmin Foundation's hiring records requires internal access to their HR database. And creating a coherent identity — employment history, institutional affiliations, credential verification — that requires either fabrication at the source or retroactive insertion into multiple databases simultaneously."
"Government level," Yeji said.
"At minimum. Someone with access to the kind of systems that government intelligence agencies use for creating cover identities. Or—" He tapped the legal pad. "Someone with System-level access to digital infrastructure."
The distinction mattered. Government fabrication meant the Bureau, or a comparable agency, had planted the researcher. System-level access meant Dohyun or someone with his capabilities had done it. The first scenario pointed to Yoon's world — the institutional machinery of state intelligence. The second pointed back to the man who'd sat across from them at Mapo Station and vibrated at dungeon frequency.
"Third option," Jihoon said. "Both. Government resources for the academic records, System access for the Foundation's internal systems. A collaboration between entities that shouldn't be collaborating."
"That's worse."
"That's worse."
Changwon's door opened. The veteran tank emerged into the hallway with the deliberate, controlled movement of a man managing three fractured ribs — each step calculated, each breath shallow, the body's entire locomotive system reorganized around the injury's demands. He wore a loose t-shirt. The bruises on his left side were visible where the fabric draped — the yellow-green map of deep tissue damage processing, the body's slow cartography of healing.
"I heard my name," Changwon said. He hadn't. His name hadn't been spoken. But the veteran's instinct for conversations that involved tactical assessment was as sharp as his instinct for incoming strikes — twenty years of field operations had built a sensitivity to the atmosphere that planning sessions generated, and that atmosphere had leaked through the thin walls.
"You should be resting," Jihoon said.
"Been resting for five days. My ribs are cracked, not my brain." The veteran pulled a chair from the table. Sat — the sitting itself a controlled operation, the descent managed in stages with his right hand on the chair back and his left arm pressed against his side to stabilize the fracture zone. "Brief me."
Jihoon briefed him. The ghost researcher. The fabricated identity. The three-system access requirement. The two or three possibilities for who could have done it.
Changwon listened with the stillness that twenty years of operational briefings had produced — the stillness of a man who absorbed information the way he absorbed physical impacts, with the entire body rather than just the relevant part. His eyes didn't move. His breathing stayed shallow and even. Only his jaw worked, the slight grinding of molars that was his processing tell.
"The contract," he said when Jihoon finished. "Three months to termination. Self-erasing."
"Yes."
"What's the date?"
Jihoon checked the legal pad. "The contract began nine months ago. February start. Termination clause activates in late April. Roughly ten weeks from now."
"So whatever she's there to do, it finishes in ten weeks." Changwon's eyes narrowed. The tactical assessment running — the veteran applying field operation logic to an intelligence problem, because field operation logic and intelligence logic shared the same skeleton. "A nine-month placement with a self-destruct clause. That's not research. That's a mission. Research is open-ended. Missions have timelines."
"What kind of mission takes nine months inside a facility that's feeding energy to trapped fragments?"
"The kind that requires long-term access to equipment and data that the mission operator doesn't own." Changwon shifted. The ribs registered the shift — his jaw tightened for a fraction of a second before the breathing adjusted. "Think about it from an operational perspective. You want to feed the fragments. You need the Cheonmin Foundation's probe infrastructure to do it. You can't build your own probes — the technology is proprietary, classified, and monitored. So you place someone inside the facility. Someone who can access the probes. Modify them. Redirect their output. Add feeding parameters to the existing research protocols."
"A saboteur who doesn't build the weapon," Yeji said. "She repurposes the weapon that's already there."
"And when the repurposing is complete — when the feeding protocols are embedded in the probe software deeply enough that they run automatically without her presence — the contract terminates. She disappears. The probes keep feeding. The Foundation's legitimate researchers never know the protocols were modified because the modifications look like normal research parameters."
The kitchen was quiet. The refrigerator humming. The radiator clicking. The ambient machinery of a safe house that didn't know it was hosting a conversation about sabotage infrastructure that operated on a timeline measured in weeks.
"Ten weeks," Jihoon said. "If Changwon is right — if she's embedding automated feeding protocols — then in ten weeks the probes run themselves. She vanishes. The feeding continues without a human operator."
"Which means—"
"Which means we have ten weeks to identify her, understand what she's done to the probe systems, and reverse it. After that, the sabotage infrastructure is autonomous and the person who built it doesn't exist anymore."
Changwon grunted. The sound carried satisfaction — a veteran whose tactical instinct had produced an assessment that the party leader confirmed. "We need to get inside that facility."
"We need to get inside the facility without alerting whoever planted her that we know she exists."
"Yoon's contact."
"Yoon's contact is already at risk. The longer the contact operates inside the Foundation's records, the higher the probability of detection. We need a different approach."
The kitchen held the problem. Three people at a table. A swordsman with a failing right hand. A tank with cracked ribs. A summoner at fifty-two percent. The math of their capability versus the problem's requirements — the same math that had been wrong in Chungcheong, the math that was always wrong when the problem exceeded the resources and the resources were what you had and what you had was never enough.

The second splinter resonance attempt happened at 2 PM. Yeji's bedroom. Door closed. The same cross-legged position on the thin carpet. But this time, not alone.
*Yuna,* Eunsoo said. Inside the bond. The S-rank healer addressing the D-rank healer with the tone that senior medical staff used when delegating to junior staff in a procedure they hadn't fully approved. *Your role is stabilization. Anti-inflammatory support on the tissue surrounding the splinter. The same intervention you performed last night. Minimum output. Do not attempt to interact with the splinter's frequency. Do not attempt to heal the splinter itself. You are managing the collateral environment. Nothing more.*
*Understood,* Yuna said. The young healer's voice carrying the steadiness of a person who'd been told exactly what to do and who preferred exactly-what-to-do to ambiguity.
*Yeji. Same parameters as yesterday. Three percent aperture. Frequency matching. You will attempt to sustain the maintenance signal for as long as the channel can support it. I will monitor capacity drain in real time. The moment I call stop, you stop. No arguments. No 'one more second.' Stop.*
"Understood."
*Begin.*
Yeji opened. Three percent. The inward focus. The recursive lens-looking-at-lens disorientation that she was learning to navigate by not navigating it — by accepting the vertigo rather than fighting it, the way swimmers accepted the water's resistance rather than trying to move through it dry.
The splinter. There. At the fifty-two-percent mark. Its frequency slightly lower than baseline — the point-three-hertz reduction that Yuna's healing had induced the previous night. Still humming. Still present. Still the shard of glass in the muscle.
Yuna's warmth arrived. Gentle. The D-rank healing output touching the inflamed tissue around the splinter — the same careful, specific application that had reduced the swelling by twelve percent. The channel's tissue responding. Softening. The defensive inflammation easing as the healing addressed the body's alarm response.
Yeji waited. Thirty seconds. A minute. Letting Yuna's stabilization take effect before attempting the frequency match. The tissue around the splinter relaxing from its guarded state. The channel's internal environment calming.
Then she reached.
Her [Requiem]'s native frequency, pushed upward. Toward the splinter's pitch. The gap narrowing. The interference pattern beating between the two frequencies — slower this time, the approach steadier, the technique improved by the data from yesterday's attempt. She knew the target frequency now. She knew the pitch. The matching was less groping in the dark and more tuning to a remembered note.
Contact. The harmonic lock. The two frequencies aligning and producing the maintenance signal — the structural warmth, the frequency of walls holding, cages intact.
The drain started immediately. Channel capacity bleeding. Fifty-two. Fifty-one point eight. Fifty-one point five.
But slower. The bleeding was slower. Yesterday: one percent per second. Today, with Yuna's stabilizing warmth cushioning the surrounding tissue: the drain rate dropped. Not halved, but reduced. The channel burning fuel at approximately 0.6 percent per second instead of 1.0.
The maintenance signal held. Five seconds. Seven. Ten. Twelve.
*Stop,* Eunsoo said. Not sharp — measured. The clinical call based on data rather than panic. *Channel at fifty percent. Stop now.*
Yeji released. The frequency match dissolving. The maintenance signal dying. The migraine surging — but less than yesterday. A wave rather than a spike. The cost of twelve seconds versus four, and yet the wave was more manageable.
*Fifty percent,* Eunsoo confirmed. *Two percent loss over twelve seconds. The drain rate improved by forty percent compared to yesterday's attempt. Yuna's stabilization reduced the collateral tissue damage, which reduced the energy expenditure required to maintain the frequency match.*
"Twelve seconds," Yeji said aloud. Her voice rough but functional.
*Twelve seconds at fifty percent capacity. Approximately eighty-three seconds of total production time remaining at the current drain rate before channel depletion.* A pause. The clinical calculation arriving. *Yeji. Below fifty percent, the channel's architecture enters a different operational regime. The safety margins narrow. Recovery becomes non-linear — slower, less predictable, and potentially incomplete. Yesterday you dropped from fifty-six to fifty-two and lost the ability to return to fifty-six. If you drop below fifty, you may not return to fifty. Each experiment reduces the ceiling permanently.*
The permanently hung in the bond's acoustic space. The word that changed the math from recoverable to directional. Every attempt cost capacity that might not come back. Every twelve seconds of maintenance signal production was purchased with channel integrity that the channel might never regenerate.
*But the drain rate improved,* Yuna said. Small. Tentative. The D-rank healer standing at the edge of a conversation between her summoner and the S-rank healer and offering the data point that her participation had produced. *If I can reduce the drain further — if we practice the stabilization—*
*Diminishing returns,* Eunsoo said. *Your healing addresses the collateral inflammation, not the fundamental energy cost. You can make the process more efficient. You cannot make it free. And each attempt starts from a lower ceiling than the last.*
*Then we need to find a way to raise the ceiling,* Yuna said.
*We need to not lower it further,* Eunsoo corrected. *Preservation before experimentation. That is basic medical protocol.*
*Basic medical protocol assumes the patient has time,* Yeji said. Inside the bond. The words directed at Eunsoo but meant for all of them. *We have ten weeks before the ghost researcher's contract terminates. After that, the feeding infrastructure runs itself. The guardians keep degrading. Seven to ten years becomes — what? Five? Three? And my channel ceiling keeps dropping anyway because the splinter is there and the splinter isn't leaving on its own.*
The silence after that was Eunsoo's. The healer processing the argument that patients made when the medical recommendation conflicted with the operational timeline and the timeline was real and the recommendation was also real and the two realities occupied the same space without resolving.
*I will develop a recovery protocol,* Eunsoo said. *A procedure for maximizing the channel's regeneration between attempts. Yuna's anti-inflammatory work, combined with targeted rest patterns and restricted perception use. If I can accelerate the recovery rate — even marginally — the interval between attempts shortens and the cumulative loss decreases.*
*That's a start.*
*It is a start. Not a solution. I want that distinction on record.*
*Noted.*

Junghwan came back from his supply run at 4:30 PM with grocery bags and something else. The something else was visible in his posture — the twenty-three-year-old carrying himself with the energy of a person who had information and who was managing the information's weight in his body, which was different from the way he carried groceries and which Jihoon noticed immediately.
"What," the swordsman said. Not a question. A read.
Junghwan set the bags on the counter. Rice. Eggs. The instant ramyeon that constituted safe house cuisine. He placed each item carefully, the domestic mechanics serving as the preamble to the thing he actually wanted to discuss.
"I made a call," Junghwan said. "Two days ago. Before the supply run."
Jihoon's eyes hardened. The swordsman's expression shifting from attentive to alert — the micro-transition that occurred when a party member disclosed unauthorized action and the disclosure's timing indicated that the action had been assessed by the party member as potentially useful and potentially problematic and the party member had chosen to reveal it based on the useful side of the assessment.
"To?"
"Kyungmin. Lee Kyungmin. We were at the hunter academy together. Same year. He went into research, I went into field operations. He works at the Cheonmin Foundation's main office in Songpa."
"The main office," Changwon said from the kitchen table where the veteran had remained, the ribs preventing casual movement. "Not the classified facilities."
"The administrative hub. HR, accounting, general research coordination. The boring side of the Foundation." Junghwan leaned against the counter. His hands at his sides — not warm, the fire mana at low reserve from yesterday's expenditure, the C-rank's recovery slower in the winter ambient density. "I called him to catch up. That's the cover. Two academy classmates talking shop. Normal."
"What did you actually call him for?"
"I asked about internal transfers. General question — 'hey, you guys hiring, things expanding over there?' The kind of question a field hunter asks when he's thinking about career options."
"And?"
Junghwan's jaw tightened. The twenty-three-year-old processing the next part — the part that had produced the posture and the energy and the need to arrange groceries before speaking.
"Kyungmin said something weird. He said the Foundation's been restructuring for the past year. New divisions. Budget reallocations. Normal corporate stuff on the surface. But one division — he called it 'Special Projects' — was created eight months ago and nobody at the main office knows what it does."
"Nobody knows."
"That's the weird part. Kyungmin works in accounting. He sees the budget allocations. Special Projects has a budget that's three times the size of the entire geological survey division. The largest single budget item in the Foundation. And when he tried to pull the allocation details — the line items, the vendor payments, the personnel costs — the system returned an access error. Classification level above his clearance."
"An accounting employee can't see the accounting for one of his own organization's divisions."
"The budget exists. The division exists. The details are classified above the standard Foundation clearance level. Kyungmin's been with the Foundation for four years. He has standard research clearance. He can see every other division's budget down to individual purchase orders. Except this one."
Changwon leaned forward. The ribs punished the movement — his left arm pressing against his side in the stabilization gesture that had become habitual. "Eight months ago. The ghost researcher's contract started nine months ago. Special Projects was created eight months ago."
"One month after she arrived."
The timeline clicked. Not proof — correlation. But the correlation was sharp enough to cut. A fabricated researcher enters a satellite facility. One month later, a classified division appears at the main office. The division's budget is enormous. The division's activities are invisible even to internal accounting. The division's creation coincides with the period during which the probe feeding schedule was established.
"How much?" Jihoon asked. "The budget."
"Kyungmin didn't give me a number. He said 'you don't want to know' and then he changed the subject. But he changed the subject the way people change subjects when the subject scared them, not when the subject bored them."
"Your classmate is in danger," Yeji said. Standing in the kitchen doorway. She'd come in during Junghwan's debrief, drawn by the voices, the migraine receding enough to allow vertical movement. "If Special Projects has classified its own accounting and an accounting employee has been asking questions—"
"He didn't ask questions. He ran into the wall and stopped." Junghwan's voice carried a defensive edge — the tone of a person who'd considered the risk and who needed the consideration acknowledged. "Kyungmin is careful. He's an accountant. He noticed the anomaly, filed it mentally, and didn't push. He told me because I'm a friend who asked a casual question at the right time."
"And if the Foundation monitors internal communications?"
"We used a personal line. His personal phone, not the Foundation network. Saturday afternoon. He was at home."
"Personal lines aren't secure against System-level surveillance," Changwon said. Flat. The veteran's assessment delivered without judgment but with the weight of a man who'd spent twenty years understanding how surveillance worked and who understood that personal phones were personal in name only.
"I know." Junghwan's hands opened at his sides. The gesture of admission — the twenty-three-year-old accepting the criticism. "I weighed it. A casual call between academy classmates doesn't flag surveillance algorithms. The content was general. I didn't mention probes, feeding, guardians, or Yeji. If someone's monitoring Kyungmin's calls, they heard two hunters talking about job markets."
"And if they're monitoring your calls?"
"Then they already know where we are and none of this matters."
The kitchen absorbed the logic. Junghwan's assessment was either correct or catastrophically wrong and the difference between the two was unknowable and the unknowability was the permanent condition of operating in an information environment that might be compromised at every level.
Jihoon's left hand tapped the table. Once. The swordsman's processing gesture.
"Special Projects. Ghost researcher. Probe schedule correlation. Three data points that converge on the same conclusion: the Cheonmin Foundation — or a faction within it — is operating a feeding infrastructure that's been designed to run autonomously." He looked at Junghwan. "Your call was a risk. The intelligence is valuable. Don't contact Kyungmin again."
"Roger that."
"I mean it, Junghwan. Not a text. Not a check-in. Nothing. If Special Projects is what we think it is, anyone asking questions inside the Foundation is walking on glass."
The fire-type nodded. The acknowledgment carrying the weight of a young man hearing his party leader's concern and recognizing that the concern was operational and personal simultaneously and that the simultaneity was the thing that made Jihoon's leadership work.

The note appeared under Yeji's door at 11:23 PM.
She was lying on the bed. Not sleeping — the fifty-percent migraine's restlessness compounding with the day's information. The ghost researcher. The three-month deadline. Special Projects. Junghwan's risk. Changwon's tactical assessment. The maintenance frequency's twelve-second window that cost two percent each time and whose cost was directional and permanent.
A sound. Paper sliding across the gap between door and floor. The specific whisper of a folded sheet crossing carpet.
Yeji looked down. A piece of notebook paper. Folded once. The crease precise — Hayeon's crease, the analyst's fold as deliberate as everything else about her.
She picked it up. Unfolded.
Three words in Hayeon's handwriting. The script tight, controlled, the letters formed with the pen that lived behind her right ear.
*Check Building 7.*
No signature. No context. No explanation. Three words and the trust required to write them and slide them under the door of the woman who'd spent a week managing the writer's information diet and whose diet management the writer had confronted twenty-four hours ago in a hallway conversation that hadn't resolved and that the three words were apparently the resolution's first offering.
Yeji stared at the note.
Building 7. She didn't know what Building 7 was. The number meant nothing to her. The note assumed she would find out — or that the note's meaning would become clear when matched against other information. Hayeon wasn't the type to give partial intelligence accidentally. If the note said "Check Building 7" without context, the absence of context was itself a message: I have Bureau access that you don't. I used it. I found something. I'm giving it to you despite being excluded. The rest is your problem.
She got up. Crossed the hallway. Knocked on Jihoon's door. The swordsman opened it in four seconds — awake, dressed, the party leader who slept in the clothes that emergencies required.
"Hayeon," Yeji said. She held up the note. "Building 7. Mean anything to you?"
Jihoon read the three words. His expression didn't change. The swordsman's face was the controlled instrument that fifteen years of field operations had calibrated — the instrument didn't move unless the movement served a purpose.
"Building 7 is a Cheonmin Foundation designation," he said. Quiet. The volume of a man who was aware that the hallway was shared space and that Hayeon's room was eight feet away and that the eight feet included walls that were, as the analyst had recently demonstrated, thin. "Yoon mentioned it once. Early in the briefing cycle. A warehouse facility. Logistics and storage. It doesn't appear on the Foundation's public facility list."
"It doesn't appear."
"Ghost building. Like the ghost researcher. Infrastructure that exists but isn't listed. Yoon noted it as an anomaly and moved on because the probe facilities were the priority."
"And Hayeon found it."
"Hayeon has Bureau database access. Standard liaison clearance. She can pull facility registrations, property records, utility connections. If Building 7 has a physical address and draws power and water, it exists in municipal databases that the Bureau can query."
Yeji looked at the note. The three words. The analyst's handwriting.
Hayeon had been told she was a valve. A conduit. An information pipe whose flow was controlled by people who didn't trust her with the full picture. She'd confronted Yeji about it. She'd said she understood. She'd said she'd continue doing her job.
And then she'd done her job.
Not the job they'd assigned her — the monitoring, the documenting, the writing of reports that served as controlled transmissions. Her actual job. Intelligence analysis. Finding signals in noise. Pulling records. Connecting dots. Using the access she had to look at things that nobody had asked her to look at because nobody had asked was the gap between being managed and being effective and the gap was where analysts lived.
"She's ahead of us," Jihoon said. The swordsman's voice carrying something that might have been respect, delivered in the register of a man who'd spent fifteen years evaluating field competence and who recognized it when it slid under a door at 11:23 PM on a Tuesday.
Yeji folded the note. Put it in her pocket. The paper warm from her hand.
In the bond, Minwoo stirred. The ghost tank's awareness touching the surface of the covenant — the dead father who'd been quiet for days, watching, processing.
*Ask her to join the debrief,* Minwoo said. *Not as a valve. As a person who found something nobody else found. She earned a seat at the table, kid.*
Yeji stood in the hallway between Jihoon's open door and Hayeon's closed one. The eight feet of corridor. The thin walls. The analyst behind the closed door who'd heard enough through those walls to know what they were looking for and who'd used her own resources to find something and who'd delivered the finding in three words on a folded piece of paper at 11:23 PM.
She looked at Jihoon.
Jihoon looked back. The swordsman's assessment running — the operational calculation, the security implications, the risk of inclusion versus the cost of exclusion. The calculation took three seconds.
Then he nodded. Once.
