Seungwon was standing outside the cave entrance when they arrived. Not sitting. Standing. Feet apart, arms at his sides, the posture of a man who'd gotten up from his usual rock and hadn't been able to sit back down. His thermos was on the ground, cap off, coffee cooling in the afternoon air.
"Nothing," he said when Yeji and Junghwan reached him. "Ninety minutes of nothing. No thermal variance. No acoustic. No breathing, no counting, no words. The Bureau sensors are flat."
The cave exhaled warm air. Residual. The heat of rock that had been warmed by a person's fight to stay alive, now cooling the way all warm things cooled when the source was gone.
"Seungwon. Close your eyes. Focus. Try to hear anything. Anything at all."
He didn't argue. Didn't question. Closed his eyes and tilted his head and stood at the cave entrance for forty-five seconds with the stillness of a B-rank utility hunter who'd learned to measure mana readings through patient silence.
"There's something," he said. Quiet. Uncertain in a way that Seungwon was never uncertain. "Not a voice. Not counting. It's — I don't know. Like hearing a refrigerator hum. You don't notice it until you listen for it and then you can't unhear it. But it's not a person humming. It's a machine."
*Eunsoo?*
*A background hum from the fragment could indicate the conversion process running without a conscious subject resisting it. If the subject has entered dormancy, their resistance stops, and the fragment's base processing becomes audible without the overlay of conscious output. Or, and this is less likely but possible, the hum is the subject's consciousness at its absolute minimum. A pilot light. The smallest possible expression of awareness, below cognitive function, below memory, below identity. Just the fact of existing, maintained at the lowest possible energy expenditure.*
*How do I tell which one?*
*Without [Requiem] contact, you can't. But there's a proxy. If the hum changes in response to external stimulus, something conscious is producing it. A machine hums at a constant frequency. A person's hum changes when they hear a new sound.*
"Seungwon. Talk to the cave. Same thing you did the first time. Introduce yourself. See if the hum changes."
He opened his eyes. Looked at the cave entrance. Looked at Yeji.
"I've been talking to him for two weeks," he said. "I told him my name. I told him about the weather. I told him about my sister's dog because I ran out of things to say on the third day and the dog was the first thing I thought of." He wasn't complaining. He was stating the inventory of a man who'd given everything in his communication toolkit to a rock that might no longer be listening. "And then he started saying words back. Bridge. Home. Minseo. And now he's quiet and you want me to talk again like talking changes anything."
"It might."
"It might not."
"Then it costs nothing to try."
Seungwon looked at her for two seconds. Turned to the cave. Squared his shoulders the way he had the first time, the day Yeji had brought him here and he'd introduced himself to a fragment that nobody else could hear.
"Hey," he said. His voice went into the cave and the cave gave it back as echo. "It's Seungwon. Thursday afternoon. It's about 14 degrees outside. Cloudy. Yeji's here. The summoner I told you about."
Nothing.
"The dog's fine, by the way. My sister sent a photo this morning. He's wearing a sweater because my sister is the kind of person who puts sweaters on dogs." A pause. "If you're in there, I'd appreciate it if you'd let me know. One word. Any word. A number. Anything."
The cave. The echo. The mountain, holding its breath.
Seungwon stood for thirty seconds. Yeji counted. Junghwan stood behind them, silent, the fire-type's presence a steady warmth in the cold afternoon.
"The hum changed," Seungwon said.
"Changed how?"
"Got louder. For a second. When I said 'Yeji.' Like it heard the name and — pushed." He tilted his head again. Listening hard, the veins in his neck visible from the strain. "It's back to baseline now. But it responded. Something in there responded to a name."
Not dead. Not gone. Dormant. The Gwanak subject had burned through his reserves, collapsed into the minimum possible consciousness, and was sitting in the stone at the pilot-light level that Eunsoo had described. The hum of a person who was no longer counting, no longer speaking, no longer remembering, but was still, at the most basic level, there.
"Can you hear anything else?" Yeji asked. "Words? Breathing?"
"No. Just the hum. And it only changed for a moment." Seungwon opened his eyes. "He's barely there."
Barely there. The man who'd counted to a hundred for two weeks. Who'd whispered bridge and home and Minseo and river between the numbers. Who'd grabbed Yeji's channel with the desperation of a drowning man and been told to let go and had let go. Who was now a hum in a mountain, a pilot light in stone, the smallest possible proof that consciousness still existed.
"How long can he stay like that?" Yeji asked, the question directed inward.
*Eunsoo?*
*Unknown. The dormancy state could be stable or it could be terminal. If the subject's consciousness has reached a sustainable minimum, they could persist indefinitely at this level. If the minimum is below the conversion process's dissolution threshold, they'll continue to degrade even in dormancy. Without direct assessment, I can't determine which.* The healer paused. *But he's not gone. The response to the stimulus confirms that. He heard a name and reacted. That's consciousness. Reduced, damaged, possibly irreversible, but present.*
Present. The word that mattered. Not well, not recovering, not fighting. Just present. Still in the building. Still answering when someone knocked.

Junghwan drove them back. The afternoon traffic was heavy and the drive took fifty minutes.
On the highway, Yeji ran the analysis with Eunsoo. The conclusion was the same from every angle: the shallow pathways in Yerin's and Soyeon's bonds could still be cleared safely. The deep ones could not. Fourteen grid connections that they couldn't touch, carrying their fractions of energy toward the grid, connected to a monitoring system that now knew someone had tried to interfere. Eunsoo thought a different approach might work for the deep pathways eventually. Slower. Less like surgery, more like dissolution. But the timeline was months, not weeks. The technique didn't exist yet.
Junghwan had been listening to her half of the conversation. He'd learned to fill in the gaps.
"So we're stuck," he said.
"We're stuck on the deep pathways. The shallow ones are still clearable."
"That's not stuck. That's half a solution."
"Half a solution isn't enough."
"Half a solution is better than no solution. And no solution is where we were a week ago." Junghwan turned onto the main road. "You proved the concept. You can remove grid pathways. Not all of them, not yet, but some. That changes the math."
He was right. The direction was away from the trap and toward something that might eventually look like rescue.

The apartment. Seven PM. Boyeon had grilled samgyeopsal on the table burner, with lettuce wraps and ssamjang and enough side dishes that the kitchen table looked like a restaurant display. Four people eating meat that Boyeon had prepared because feeding people was her operational contribution and the operation needed feeding as much as it needed tactics.
After dinner, the others drifted. Changwon to reports. Junghwan to call Seungwon. Boyeon to the dishes.
The table cleared except for Jihoon's notebook and Yeji's empty plate.
"The conduit," Jihoon said. "We haven't talked about it directly."
"We talk about it every briefing."
"We talk about the threshold. The utilization. The margin." He closed the notebook. "We don't talk about what happens to you."
"The conduit activates. The splinter converts [Requiem] into a harvesting function. The spirits in my bond are drained into the grid."
"And you?"
She didn't answer. The conduit records had been specific about the spirits and vague about the summoner. The summoner's fate was listed in three words that Eunsoo had translated with unusual reluctance: *vessel function ceases.*
"The summoner's channel burns out," Yeji said. "The conduit draws too much energy through the splinter. The mana channel collapses. What happens after that is unclear."
"Cessation of what?"
"Of the conduit function. Of [Requiem]. Of the mana channel." She met his eyes. "Of me, probably. But the records aren't explicit."
Jihoon's jaw shifted. The leftward movement. The microexpression she'd cataloged months ago. Processing.
"Probably."
"The conduit has never activated in someone who had support. Allies. A healer in the bond. The twelve cases in the archive were isolated summoners operating without knowledge of what they were. I have Eunsoo. I have you. I have a team and a plan and a partial technique for reducing the grid's hold. The historical outcome doesn't account for that."
"That's not reassurance. That's a variable."
"Variables are all I have."
The kitchen. The after-dinner quiet. Boyeon's dishes in the sink. The apartment that had become the operational center for something none of them had been trained for.
Jihoon was quiet for twelve seconds. She counted.
"Every resource in this operation flows through you," he said. He opened his hands. Both of them. The right hand steady, the left hand trembling. "If you burn out, the bonds break. The spirits are lost. The broadcasts fail. Everything we've built collapses."
"I know."
"I'm not saying this to add pressure. I'm saying this because you need to hear that the people in this apartment understand the stakes and we are not going to let you carry them alone." He closed his left hand. The tremble stopped, the grip holding through force of will. "Whatever the conduit is, whatever the System designed you to be, you're also a member of this party. And this party doesn't lose people."
Yeji looked at him. At the notebook. At the brace on his arm and the hands that were both open and the face that was not performing leadership but simply being it.
"Okay," she said.
"Okay what?"
"Okay, you won't let me carry it alone. I hear you."
Jihoon picked up the pen. Opened the notebook. Wrote something. One word. Then he looked up.
"Friday. Morning briefing. We need to integrate Yeonji's Yeongdeungpo data with the existing site network. Hayeon's calling in with the HOC hearing prep. And Eunsoo needs to present her findings on the deep pathways. If the System's monitoring is watching for patterns, we need to understand the pattern threshold before it finds us."
Back to operations. Jihoon's way: say the thing, mean the thing, then get back to the thing that needed doing.
Yeji took her plate to the kitchen. Boyeon washed it and placed it in the drying rack with the others. Clean plates. Ready for tomorrow.
In the bond, six spirits settled into the night. Minwoo told Nari a story about a rabbit who lived on the moon and counted stars, not because the story was true but because the telling of it made the dark less dark. Eunsoo planned tomorrow's session. Yerin was quiet, holding the knowledge that thirteen roots in her bond would not be pulled. Soyeon listened to the story. Yuna's dampening field ran at 40%, steady, the pilot light of a spirit who'd given too much and was learning to function with less.
In Gwanak, a man hummed in stone. In Mapo, a woman counted to forty-seven. In Songpa and Suwon, two people held to broadcasts that kept them alive. At Yeongdeungpo, a new set of voices waited to be documented by a woman with three notebooks and a sensitivity that nobody had believed was real.
The operation continued. Too slow, too rough, but forward. Because the alternative was stillness, and stillness in this work meant someone in stone stopped counting, and Yeji would not be still while there were numbers left to hear.
