The call came at 1430 as they crossed the boundary between Gwacheon and Uiwang, the suburban development thinning into the agricultural fringe that bordered the metropolitan area's southern edge. The grid's sensor presence here was sparse — the telecommunications infrastructure serving farming communities and scattered residential clusters with the minimal coverage that rural areas received.
The prepaid phone. Not Dohyun's contact. Minho's guild line.
"The briefing happened," Minho said. "The oversight board's chair asked three questions. The first: whether Dohyun's legal team had advance knowledge of the departure. The second: whether the administrative stay was filed with the specific intent of creating a departure window. The third: whether Dohyun's guild had provided material support to a Calamity-class subject during the departure."
"The answers."
"Dohyun's legal team answered all three honestly. The stay was filed on procedural grounds related to the calibration fraud. The departure occurred during the stay's protection window. The guild did not plan or coordinate the departure." A pause. "The third answer was a half-truth. The apartment, the provisions, the prepaid device — those are material support that predates the departure by four months. But the legal team argued that preparation for contingencies is a standard guild operational practice, not coordination of a specific event."
"Did the board accept it."
"The board chair didn't rule. The briefing was informational, not adjudicatory. But—" Minho's voice shifted. The tone that preceded institutional complications. "The Foundation for Hunter Safety had a representative present. Uninvited, same as Kwon Mirae at the day seventy-eight committee. The representative presented a supplementary brief arguing that the guild's four-month preparation demonstrates premeditated intent to extract a Calamity-class subject from supervised evaluation."
Premeditated extraction. The legal characterization that transformed Dohyun's contingency planning into evidence of conspiracy.
"The board's response."
"They've scheduled a formal review session for day ninety-six. Two days from now. The formal review has authority to dissolve the stay, impose sanctions on Dohyun's guild, and refer the case to the Association's criminal investigation division."
Day ninety-six. The original transfer timeline. The institutional machinery's different paths converging on the same point — the committee's transfer order, the Foundation's dissolution motion, and now the oversight board's formal review, all landing within forty-eight hours of each other.
"There's something else," Minho said. "Dohyun received a communication through an unofficial channel. Not the guild's institutional line. A personal message."
"From."
"A researcher. Name: Oh Taeyoung. Senior fellow at the Korea Institute for Awakened Studies — the independent research body, not the Association's research division. He's been studying healer-class mutation theory for six years. Published papers on the pre-System healer capacity data. He says—" Minho paused. "He says he wants to help."
Oh Taeyoung. A name Sora hadn't heard. The Korea Institute for Awakened Studies — she knew the institution by reputation. Independent funding, not Association-affiliated. Academic research mandate. The kind of organization that published papers the Association cited when convenient and ignored when inconvenient.
"What kind of help."
"He says he has a research facility outside Seoul. Private funding. Equipment for mana architecture analysis. He's offering access to the facility, analysis of your hexagonal configuration using his own instrumentation, and — this is the part Dohyun flagged — he says he has data on the pre-System healer mutations that isn't in the Association's restricted archives."
Independent data. Data that existed outside the institutional framework that the Association controlled, the oversight board monitored, and Kwon Mirae's division accessed.
"How did he contact Dohyun."
"Through a colleague at the guild's research liaison office. The message came two hours after the media coverage. He saw the broadcast and reached out." Minho paused. "Dohyun's assessment: the timing is opportunistic. A researcher who's been working on healer mutation theory for six years sees the Calamity-class healer on the news and immediately moves to make contact. That's professional ambition, not altruism."
"But."
"But the independent data is real. Dohyun's contact verified Oh Taeyoung's publication record. Six papers on healer-class mutation in the Journal of Awakened Biology. Two on pre-System capacity modeling. His research predates your emergence by four years."
Four years of studying the thing Sora had become. The theoretical framework for healer-class mutation, developed by a researcher who'd never had access to a living example.
Until now.
"He wants to study me," Sora said.
"He wants to study the architecture. Your hexagonal configuration is the first empirically documented case of complete healer-class mutation since the System update. His entire research program is built on theoretical models that your existence proves or disproves." Minho's voice level. "Dohyun's assessment: he's genuine about the research. Whether he's trustworthy beyond that is a different question."
Sora looked at the road ahead. The Uiwang countryside: agricultural plots, scattered residential clusters, the mountains to the east that separated the metropolitan basin from Gyeonggi Province's interior. The grid's sensor coverage thin enough that the passive reception detected no nearby sampling points.
"Where is the facility."
"Yongin. Southeast of Suwon. Approximately thirty kilometers from your current trajectory."
Thirty kilometers. A day's walk, or a short vehicle trip if they had access to a vehicle they hadn't used and that wasn't connected to any logged identity.
"The facility is outside Seoul's grid coverage?"
"Outside the metropolitan grid. Yongin has its own municipal sensor network, but the coverage is municipal-scale — major intersections and commercial zones. The facility itself is in a rural research park outside the municipal boundary."
Rural. Off-grid. Equipment for architecture analysis. Independent data on pre-System mutations.
And a researcher whose professional ambition had been waiting six years for exactly the kind of subject that had just appeared on every news broadcast in the country.
"Eunji," Sora said.
"What about her."
"She's inside the Association. She filed the disclosure. She has access to the pre-System archives. She's been our primary research contact." Sora paused. "Has she communicated since the departure?"
"Nothing through Dohyun's channels. Nothing through the guild's institutional line. Nothing through any contact we can access." A pause. "She may be maintaining silence to protect her position. The disclosure she filed is in the institutional record — if she's seen communicating with anyone connected to the departure, the Association's internal affairs division has grounds to suspend her access."
Eunji's position inside the Association. The position that gave her access to the archives, the pre-System foundation study's appendices, the research program's documentation. If that access was revoked, the investigation's internal information pipeline closed.
"Or she's been instructed not to communicate," Sora said.
"That's the other possibility."
The clinical assessment running its differential diagnosis. Two possibilities, insufficient data to distinguish between them. Eunji maintaining tactical silence to preserve her access, or Eunji's access already compromised by institutional response to the departure.
"The researcher," Sora said. "Oh Taeyoung. What does Dohyun recommend."
"Dohyun recommends caution. The offer is useful — the facility, the equipment, the independent data. But the timing is suspicious, the researcher's motivations are professional rather than personal, and any contact point creates a potential leak to Kwon Mirae's division." Minho paused. "My assessment is different."
"Tell me."
"You need the independent data. The pre-System healer mutation information that Eunji accessed came through Association archives — it's institutional data, controlled, potentially curated. An independent researcher with four years of work on the same subject would have reached conclusions that the Association's archives might not support. If his data contradicts the institutional narrative, that's information the investigation needs." Another pause. "And you need the architecture analysis. The evaluation wing's scan documented the hexagonal configuration, but it was conducted by Dr. Chae under the research program's protocols. An independent analysis by a non-affiliated researcher with his own equipment provides a baseline that isn't controlled by the people who want to control you."
Simple logic. The framework controlling the data she needed was the same framework hunting her. An independent source outside it was a resource she couldn't afford to ignore.
A different kind of risk.
"Set it up," Sora said. "Through Dohyun's unofficial channel. No institutional lines. No guild communication system. If Oh Taeyoung wants access to the first empirically documented complete healer-class mutation, he can meet us at his facility tomorrow."
"Conditions?"
"Three. First: no Association notification. He doesn't tell anyone we're coming. Second: the independent data — whatever he has on pre-System healer mutations — is shared before any analysis of my architecture begins. I assess the data's value before I give him access to the subject he's been theorizing about for six years. Third: Soojin's architecture gets analyzed too. She's a developing healer-class mutation under eleven months of clockwise suppression with three surviving junctions and a counterclockwise residual that's climbing. If he's studying mutation theory, she's data he can't find anywhere else."
"Understood." Minho paused. "One thing. The media coverage has reached the hunter community. The guild's internal communications are carrying discussion about the departure. Several guild members have expressed — concern isn't the right word. Awareness. The awareness that the guild master is publicly connected to a Calamity-class subject who left supervised evaluation."
"Is it affecting Dohyun's position."
"Not yet. His guild's operational structure runs on his authority, and his authority runs on competence and track record. But authority runs on perception too, and the perception that the guild master is harboring a Calamity-class fugitive has a shelf life."
A shelf life. The social cost of association. The same mechanism that had kept hunters from working with her in Arc 1 — the fear of proximity, the reputation contamination — now extending to the institutional structure that supported her.
"Thank you," Sora said. "The 1400 briefing recording — Dohyun has it?"
"In the guild's institutional record. Secured."
"Good."
The call ended. Sora stood on the road between Gwacheon and Uiwang, the mountains to the east, the agricultural plots to the west, the metropolitan grid's sensor coverage behind them. Soojin four meters away, the compromise distance, the counterclockwise residual at whatever it had reached during the hours of walking.
"I heard enough," Soojin said.
"The researcher."
"Independent facility. Equipment. Data you don't have." Soojin looked southeast — the direction of Yongin, of the research park, of Oh Taeyoung's six years of theoretical work on the thing their bodies were doing. "And he wants what every researcher wants. Access to the subject."
"Does that concern you."
"I spent eleven months as a research subject." The flat clinical register, the voice that processed institutional experience without the emotional reaction it contained. "The question isn't whether being studied concerns me. The question is whether being studied by someone who wants to understand the architecture is different from being studied by someone who wanted to suppress it."
The distinction. The diagnostic difference between research aimed at understanding and research aimed at control. Im Byeongsoo's program had collected data to manage the mutation — to document it, suppress it, prevent it from reaching completion. Oh Taeyoung's six years of theoretical work suggested a different objective: comprehension. The academic imperative to explain a phenomenon rather than contain it.
"We'll find out tomorrow," Sora said.
They resumed walking. Southeast now. Toward Suwon's rural periphery, toward the highway-only sensor coverage, toward the facility in Yongin where a researcher had been studying the theory of what they were for four years before either of them had become the proof.
Soojin walked beside her. The four-meter distance. The three surviving junctions under their redistribution load. The counterclockwise residual climbing.
The interference pattern between their architectures humming at its low-amplitude frequency. Two healers walking through farmland. One dampened, one silent. Between them, the evidence a six-year research program had been built to find.
The sun moved west. They moved southeast.
In Seoul, the news cycle ran its chyron.
