Hayeon's timeline covered the basement's longest wall.
She'd taped notebook pages end to end — six sheets, landscape orientation, the handwriting small and precise. A horizontal line bisected the pages. Above the line: events they knew. Below the line: events they'd inferred. The analyst's methodology made visible on yellowed paint and bare concrete.
"Four hundred years ago," Hayeon said. She stood beside the wall, pen in hand, the flashlight propped on the floor angling upward to illuminate her work. The basement's single bulb provided a sick yellow light that made the paper look older than it was. "That's the keeper's stated timeframe. Absorbed during a repair attempt on the Gangwon guardian approximately four hundred years ago. Which puts the absorption somewhere around 1620. Give or take decades — a degraded spirit's sense of time isn't reliable."
The team listened from their positions around the basement. Jihoon stood. Always stood. Changwon sat against the far wall, ribs wrapped in the makeshift support that Junghwan had constructed from a bedsheet and two belts — field medicine, ugly but functional. Junghwan sat cross-legged near Changwon, maintaining his warmth output in the basement's cold. Yeji sat on the floor with her back against the wall perpendicular to Hayeon's timeline, the forty-three-percent migraine a constant companion, Yuna's dampening field running inside the bond.
"The keeper said seven keepers existed. They maintained the guardian containment — performed repairs on the prison architecture. The fragments learned the maintenance frequency by observing the repair process and adapted their assault signals accordingly. And something hunted the keepers. Something the keeper called 'the System.'"
"Problem," Jihoon said. The swordsman had been reading the timeline since Hayeon mounted it. His left hand was in his pocket. His right hand — the compression sleeve — hung at his side.
"Problem," Hayeon agreed. She tapped a date below the inference line. "The System — as we understand it, as Dohyun administers it — was established approximately forty years ago. Post-First Dungeon Break. The System's creation was a response to the dimensional incursion that killed ninety-nine percent of humanity's pre-Break population. The System uses soul-harvesting as an energy source to prevent further dimensional collapse. Dohyun has administered it for approximately twenty years."
She tapped another date. "The keeper was absorbed four hundred years ago. The keeper says the System hunted the other keepers. Four hundred years ago, the System as we know it did not exist. It wouldn't exist for another three hundred and sixty years."
The discrepancy sat on the wall in Hayeon's handwriting. Two dates. A gap of centuries between what the keeper remembered and what history recorded.
"The keeper's memory is degraded," Yeji said. "Four centuries of imprisonment inside a fragment's resonance field. Cognitive erosion. The same process that stripped Baek Seungho's name — the keeper's been enduring it for hundreds of years instead of months. Temporal accuracy could be the first thing to go."
"Possible," Hayeon said. "But the keeper didn't confuse the nature of the threat. The keeper specified: something in the living world hunted the keepers. Not fragments. Not dungeons. An organized entity that targeted [Requiem]-type individuals specifically because they maintained the guardian containment. That level of detail surviving four centuries of erosion suggests the memory's core is intact even if the dating is imprecise."
"Three options," Changwon said from the far wall. The veteran's voice carrying the lateral-thinking quality that twenty years of threat assessment produced — the ability to hold multiple scenarios simultaneously and assign relative probability to each. "One: the keeper's timeline is wrong. Four hundred years compressed or expanded by cognitive damage. The hunting happened more recently. Maybe closer to the System's actual founding."
"Two," Jihoon said. The swordsman picking up the thread. "The entity that hunted the keepers predates the System. Something else. Something that existed before the System was built and that opposed the guardian maintenance for its own reasons."
"Three," Hayeon said. She wrote it on the wall below the inference line. "The System was built on something older. The current System — Dohyun's System, the soul-harvesting infrastructure — is a new layer on top of a pre-existing structure. The keeper's memory of 'the System' isn't our System. It's an earlier version. A precursor. Something that operated under a different name or no name at all and that the keeper's degraded cognition retroactively labeled with the term that fits the pattern: a system. A structure. An organized opposition."
The basement held the three options. The flashlight's upward beam casting shadows on the timeline that made the handwriting look like it was moving.
"Option three tracks," Jihoon said. Quiet. The swordsman's assessment voice — the register he used when the tactical landscape was clarifying and the clarity was producing a picture he didn't like. "The soul-harvesting started forty years ago. But the dimensional infrastructure — the dungeons, the mana fields, the containment architecture — is older. Much older. The guardians have been holding for centuries. Someone built the containment. Someone maintained it. And then someone built a system on top of that containment that uses the thing being contained as a power source."
"Like building a power plant on top of a prison," Changwon said.
"Like building a power plant on top of a prison and then removing the prison guards because the guards interfere with the power generation." Hayeon's pen tapped the timeline. "The keepers maintained the containment. The containment kept the fragments imprisoned. If someone wanted to use the fragments' energy — to harvest the soul-energy that the fragments represent — the containment was an obstacle. The keepers who maintained the containment were obstacles. Remove the keepers, let the containment degrade, and the fragments become more accessible."
"More accessible and more dangerous," Yeji said.
"The two aren't separable. A fragment that's easier to harvest is a fragment that's closer to breaking free. The soul-harvesting requires weakened containment. Weakened containment means the fragments grow. The System's entire operational model depends on a balance between access and containment — harvesting enough energy to function while keeping the fragments imprisoned enough to prevent catastrophe."
"And the feeding," Jihoon said. "The probes. The supplemental energy."
"Accelerates the imbalance. More energy into the fragments means faster degradation of containment means more harvestable energy means faster degradation. A feedback loop. Whether intentional or accidental, the feeding is pushing the balance toward collapse."
Hayeon capped her pen. The timeline complete — or as complete as the available data allowed. Above the line: known events, dated and sourced. Below the line: inferences, connected by dotted lines that represented logic rather than proof. The analyst stepped back from the wall and looked at her work with the expression of a professional who'd built something from fragments and who recognized that the building was as strong as the fragments allowed and no stronger.
"We need more data from the keeper," she said. "The precursor. Whatever hunted the keepers before the System existed. That's the missing link. If we can identify the precursor entity, we can trace its connection to the current System and determine whether the feeding is the System's deliberate policy or something inherited from a structure that predates Dohyun's administration."
"The keeper is damaged," Eunsoo said. Aloud — Yeji channeling the healer's assessment for the team, the clinical voice translated into the summoner's mouth. "My disruption of the resonance link caused additional degradation to the keeper's communication pathways. Words are probably beyond the keeper's current capability."
"Probably?" Hayeon asked.
"Eunsoo deals in probability, not certainty," Yeji said. "The keeper might recover some function. Might not. But there are other forms of communication. Last night, before the crisis — the keeper was forming words. Before that, the signal was modulated like speech but without language. The keeper's communication may have other modes. Images. Sensations. Non-verbal transmission."
"Can you try?"
Yeji looked at Jihoon. The request — can you try — coming from the analyst who'd been included for twelve hours and who was already pushing toward the action that the inclusion made possible. The swordsman's expression was unreadable. The controlled mask of a man who was allowing the inclusion to operate while reserving judgment on the inclusion's consequences.
"One percent," Yeji said. "Passive reception. I don't push. I listen. If the keeper has something to transmit, one percent should be enough to receive it."
"Cost?" Jihoon asked.
"Minimal. One percent for passive reception burns almost nothing. The crisis happened because I opened to three percent and actively probed. This is different."
*Confirm,* Eunsoo said inside the bond. The healer's authorization reluctant but present. *One percent passive reception is within acceptable parameters. I will monitor for any expansion of the splinter's footprint. At the first sign of destabilization, I terminate the reception.*
Yeji closed her eyes. The basement's cold concrete behind her. Yuna's dampening field humming around the splinter. The team watching — five sets of eyes on the summoner who was going back to the thing that had cost her seven percentage points of channel capacity twelve hours ago.
One percent. The barest sliver. Inward. Past the surface hum. Past the maintenance layer. Down to the third sub-harmonic where the keeper lived.
The keeper was there. Faint. The presence diminished from the contact — the ancient spirit's signal reduced by the forced severance of the resonance link. What had been tired speech was now barely a murmur. What had been modulated frequency was now a wavering tone, irregular, the spiritual equivalent of labored breathing.
*I'm here,* Yeji sent. One percent. Not pushing. Receiving. The open hand rather than the reaching hand. *I'm not going to hold the connection. I'm just listening. If you have something to show me, show me. I'll receive.*
Silence. Seconds. The keeper's diminished presence registering Yeji's [Requiem] but not responding. The ancient spirit's communication pathways damaged, the forced disruption having broken something that four centuries of imprisonment hadn't broken — the ability to form words from will.
Then. Not words. Not sound.
An image.
It arrived in Yeji's perception like a photograph developed in acid — bleached, distorted, the edges dissolved. But the center held. The core of the image surviving the degradation that had consumed its context.
Mountains. High. The distinctive silhouette of Korean peaks — granite and pine, the geology of Korea's southern ranges. A ridgeline. Snow. Not modern snow — something about the snow was different, the quality of the white suggesting a different era, a different atmosphere, the pre-industrial brightness that environmental change had dimmed.
Below the ridgeline: a structure. Stone. Not a building — a temple. The architecture distinctly Korean traditional, but old. Older than Joseon. The roofline curved in a style that Yeji associated with Goryeo-period construction — the slope and curvature of tiles that pre-dated the architectural reforms of the 14th century.
And beneath the temple. Under it. The image's focus drilling downward through the stone foundation into the mountain's interior. A chamber. Carved from rock. The chamber's walls covered in — something. Not writing. Not art. Patterns. The patterns vibrating in the image with a frequency that Yeji's [Requiem] recognized.
The maintenance frequency.
The patterns on the chamber's walls were the maintenance frequency made physical. Carved into stone. The keeper's repair signal rendered in a permanent medium — the frequency that the keepers used to tune the guardian containment, preserved in rock so that the rock itself hummed at the repair wavelength.
A waystation. A place where keepers gathered. A place where the maintenance frequency lived in the walls.
The image held for three seconds. Then it dissolved. The keeper's transmission exhausting the spirit's remaining communication energy. The ancient presence retreating deeper into the splinter's interior — not gone, but spent. The effort of transmitting a single image consuming what the forced severance had left.
*Thank you,* Yeji sent into the retreating signal. *Rest. We'll find it.*
She opened her eyes.
"Mountains," she said. Her voice rough. The one-percent cost negligible — the channel unchanged at forty-three percent. The roughness was from the image itself, from the experience of receiving a memory that was centuries old and that carried the emotional residue of the person who'd lived it. "A temple. Goryeo-period. Built on a mountain. There's a chamber underneath — carved from rock, with the maintenance frequency embedded in the walls. A waystation. A gathering place for the keepers."
"Where?" Hayeon asked. The analyst already moving — to her notebook, to the bag she'd brought, the bag that contained things she'd prepared for contingencies. She pulled out a tablet. Not Bureau-issued — personal. The device dark, no network connection, the offline maps app loaded.
"Southern mountains. Granite ridgeline. High elevation. The silhouette was—" Yeji paused. The image's edges were gone. The context dissolved by the keeper's degradation. But the ridgeline's shape was specific. "Sharp peaks. Multiple summits in sequence. Running roughly east-west."
"Jirisan," Junghwan said. The fire-type spoke from his position near Changwon, his voice carrying the certainty of a person who'd spent his childhood in the southern provinces and who knew the mountains' silhouettes the way city people knew skylines. "That's Jirisan. The main ridgeline runs east-west. Cheonwangbong to Nogodan. Multiple summits. Granite and pine."
"South Korea's highest mainland mountain," Hayeon confirmed, pulling up the offline map. "Goryeo-period temples in the Jirisan range — there are several. Hwaeomsa. Ssanggyesa. Chilbulsa." She scrolled. "But you said underneath. A chamber beneath the temple. That narrows it. Most of these temples are built on slopes. To have a chamber carved into the mountain beneath the structure requires—"
"The temple sits directly on a rock formation large enough to contain a significant underground space," Changwon said. The veteran's field knowledge engaging — twenty years of operations had taken him through Korea's terrain at ground level. "Hwaeomsa is on a valley floor. Ssanggyesa is on a slope. Chilbulsa is built on a granite outcrop on the mountain's southern face. The outcrop is massive — the monks used to say the temple sits on the palm of a stone Buddha."
"Chilbulsa," Hayeon said. She tapped the map. The temple's location marker appearing on the offline image. "Seven Buddhas Temple. Elevation 850 meters. Southern face of Jirisan. Built during the Unified Silla period, predating Goryeo. Renovated multiple times. The granite base is — yes. Extensive enough for underground chambers. The temple's own records reference 'lower halls' that were sealed during the Joseon period."
"Sealed," Jihoon said.
"Sealed and forgotten. The records mention the sealing as a response to 'spiritual disturbances' that the Joseon-era monks attributed to evil spirits. The lower halls were bricked over and the brickwork was incorporated into the temple's renovation during the 17th century."
The 17th century. Four hundred years ago. The same timeframe as the keeper's absorption.

Minwoo found her in the bathroom at 2 AM.
Not literally — the ghost tank manifested in the bond's shared space while Yeji sat on the bathroom's concrete floor with the door closed and the single bulb providing the fluorescent light that bathrooms in underground apartments provided: harsh, unflattering, the kind of light that made everyone look slightly dead.
*Hey, kid.*
The voice was gentle. Not the dad-joke register. Not the warm, defusing tone that the ghost tank used to manage tension. The other voice. The one that came out when Minwoo stopped being the team's emotional infrastructure and started being a dead man who was also a father.
*Hey,* Yeji said.
*The bathroom floor, huh? This is new. Usually it's the bed-ceiling combination. The bathroom floor is an upgrade. More commitment to the misery.*
She almost smiled. Almost. The forty-three-percent migraine intercepted the smile and converted it into a wince.
*I'm not miserable.*
*Your channel is at forty-three percent. You lost seven points in twelve hours. You screamed so loud that a man with three cracked ribs sat up in his sleep. You're sitting on a bathroom floor at two in the morning in a basement that doesn't have heating.* A pause. *Kid. Come on.*
*I made a mistake. Mistakes have costs. I'm processing the cost.*
*You're burning yourself down.*
The words arrived with the weight that only a parent's voice could carry — the combination of love and accusation that parents deployed when the love was the reason for the accusation and the accusation was the shape that the love took when it was scared.
*I'm doing what needs to be done.*
*You're doing what you've decided needs to be done. Those aren't the same thing. Jihoon hasn't asked you to experiment with the splinter. Yoon hasn't ordered it. Changwon specifically warned against it. You're running these experiments because you've decided that your channel is a tool and the tool's limits are obstacles and the obstacles need to be broken through and the breaking is—*
*Necessary.*
*Destructive.* Minwoo's presence shifted in the bond. Closer. The ghost tank's spiritual mass settling beside Yeji's awareness the way a living person would settle beside someone on a bathroom floor — close enough to touch, careful enough not to crowd. *You want to hear something I've never told you?*
*Tell me.*
*I watch Somin through you. You know that. The perception work you did at Bupyeong — I see her. My daughter. Seven years old. Drawing in a school courtyard alone because she can sense things that other children can't sense and the sensing makes her different and different makes her alone.* The ghost tank's voice went rough. Not the roughness of speech — the roughness of a frequency that was carrying more than the frequency was designed to carry. *I watch her and I can't touch her and I can't talk to her and I can't be her father except through a dead man's eyes looking through a living woman's ability. And every time you damage that ability, every time you lose capacity, the window gets smaller. The view gets dimmer. The connection between me and my daughter — the one thing that surviving death gave me that death itself tried to take — shrinks.*
The bathroom held the confession. The fluorescent light. The concrete floor. The ghost tank's presence beside the summoner's awareness.
*I'm not telling you this to make you feel guilty,* Minwoo said. *I'm telling you because you need to understand what you're losing. It's not just your capacity. It's not just your operational ceiling. It's us. Me. Nari. Eunsoo. Yuna. Every percentage point you burn through is a piece of the bond that holds us together. Forty-three percent. How low does it go, kid? Thirty? Twenty? What happens to Nari when the channel can't support her? What happens to the covenant when the infrastructure fails?*
*I didn't think about it that way.*
*You're twenty-two. You're a psychology student who talks to dead people. You're not supposed to think about everything. That's why you have a team. Living and dead.* The roughness smoothing. The ghost tank's voice returning to the warm register that was his default — the warmth of a man who'd spent nine years making a child laugh and who'd channeled the laughter-making into the team that held his covenant. *But you need to start thinking about it now. Because the experiments aren't just your decision. They affect everyone in the bond. And we don't get a vote. We just get the consequences.*
Yeji pressed her palms against the concrete floor. The cold surface real under her hands. The tangible world that existed outside the bond, outside the channel, outside the war between guardians and fragments and systems.
*I'll be more careful.*
*I don't want you to be more careful. I want you to ask us before you do things that change the architecture we live in. That's not permission. That's respect.* A pause. *I'm a ghost, kid. I live inside your brain. The least you can do is tell me when you're planning to remodel.*
The almost-smile tried again. This time the migraine let it through. Small. Barely a curve of the lip. But present.
*Okay.*
*Okay.* The ghost tank's presence lingered. Not retreating. Not speaking. The silence of a father sitting beside someone who needed sitting-beside and whose sitting-beside was the thing that mattered more than the words.

The bathroom door banged open.
Hayeon. The analyst standing in the doorway with her tablet in one hand and her notebook in the other and her pen behind her ear and her eyes carrying the luminescence that intelligence analysts produced when the data converged and the convergence revealed something that the individual data points hadn't shown.
"The temple," Hayeon said. Not preamble. Not introduction. The direct delivery of a person who'd been working for hours and who'd found something and whose finding demanded immediate sharing. "Chilbulsa. I pulled the historical records — municipal archives, land registry, religious site documentation. The temple is still active. Small monastic community. Twelve monks. Maintains the traditional grounds."
"And?"
"The maintenance isn't funded by the monastic community. The temple's upkeep is underwritten by a trust fund. Established in 1923. The trust fund pays for structural repairs, groundskeeping, renovation of the traditional buildings. Approximately forty million won per year. Consistent payments for over a century."
"Who established the trust?"
Hayeon held up her notebook. The page showed a name, written in both hangul and hanja characters.
"Ahn Jeonghui."
Yeji stared at the name. Ahn. Her family name.
"The trust was established by Ahn Jeonghui in 1923 through a legal firm in Daegu that no longer exists. The firm's records were transferred to a successor practice in 1967. The successor practice maintains the trust's administration. They've been making annual payments to Chilbulsa's maintenance fund for one hundred and three years."
"Who is Ahn Jeonghui?"
"Nobody." Hayeon's voice carried the edge that analysts produced when the data trail ended in a wall. "There is no Ahn Jeonghui in any civil registry, birth record, census document, or historical archive that I can access through the Bureau's genealogical database. The name doesn't correspond to any living or deceased person in the Korean administrative record. The trust was established by someone who doesn't exist in any system. Just like the ghost researcher. A fabricated identity. But this one was fabricated a century ago."
Yeji's hands were flat on the concrete floor. The cold seeping through her palms. The name on Hayeon's notebook — Ahn Jeonghui — written in the analyst's precise handwriting. The family name that was Yeji's family name. The trust fund that had been maintaining a keeper waystation for a hundred years. The fabricated identity that had been established a century before the ghost researcher's fabricated identity was planted inside the Cheonmin Foundation.
Someone had been keeping the waystation active. For a hundred years. Under a name that shared Yeji's surname.
"The Ahn is a coincidence," Hayeon said. Reading Yeji's face. "Ahn is the fifteenth most common surname in Korea. Over seven hundred thousand people. The probability of a shared surname in a fabricated identity is—"
"Not zero," Yeji said. "Not negligible either. 1923. A trust fund to maintain a keeper waystation. Using the name Ahn. A hundred years before a woman named Ahn awakens with [Requiem] — the keeper's ability."
The bathroom's fluorescent light buzzed. The concrete walls held the buzzing and the cold and the information and the two women in the doorway — one standing, one sitting — and the space between them where the name existed and where the name's implications were growing the way implications grew when they connected to existing questions and the connections produced questions that were larger than the originals.
"We need to go to Jirisan," Yeji said.
Hayeon didn't argue. The analyst's silence was agreement — the professional assessment that the data trail pointed south and that following the trail was the next operational step and that the step was necessary regardless of where the trail led.
In the bond, Minwoo's presence stirred. The ghost tank who'd just finished telling Yeji to ask before making decisions that affected the covenant.
*Kid,* he said. *What did I literally just say?*
Yeji pressed her palms against the floor. The cold concrete. The real world.
*I'm asking,* she said. *What do you think?*
A long pause. The ghost tank processing. Then, quietly:
*I think the name on that trust fund scares me more than the fragments do.*
