Three hours into the dead channel, the silence became a weight.
Not sound-silence, the column of a hundred and twenty people couldn't be quiet. Footsteps on stone, the shuffle of packs, the child's occasional whimper when the darkness pressed too close. Breathing. Coughing. The organic noise of bodies moving through a tunnel that had never been designed for traffic. All of that continued, and none of it mattered.
The silence was consumption silence.
Raze felt it through his material-sensing the way a deaf person might feel the absence of music, not hearing the lack, but knowing it. The stone around them was dead. Not geologically, the basalt was solid, structurally sound, the fault line they followed as stable as any passage in the deep network. Dead in the way that mattered. No mana flow. No ambient consumption energy threading through the geological substrate. No background hum of the deep network's circulatory system feeding organisms and sustaining the complex web of consumption-based life that existed in the live channels.
Nothing.
The dead channel was a fossil. A geological feature that had once carried mana, the mineral deposits that sealed it still bore the residual traces of ancient flows, the quartz intrusions containing chemical signatures of consumption energy that had circulated through this fault line thousands of years ago. But the flow had shifted. The deep network's circulation had found more efficient paths, and this channel had been abandoned the way a river abandons an old meander, gradually, completely, leaving behind a dry bed that remembered water but no longer carried it.
Walking through it felt wrong. Every consumption-sensitive organ in Raze's modified body was calibrated for an environment saturated with ambient mana. His material-sensing, which normally read the stone through the medium of consumption energy flowing within it, was operating blind, reduced to purely physical sensation, vibration and density and temperature, without the rich overlay of consumption data that made the deep network navigable. His ancient core, which resonated with the mana flows the way a tuning fork resonated with sound, was silent. The 147 integrated consciousnesses, accustomed to the constant background input of ambient consumption energy, had gone quiet, not inactive, but understimulated. The biological equivalent of sitting in a sensory deprivation tank.
The column felt it too. Not just Raze, everyone. Consumption modification was universal in the deep network. Every person in the column had been changed by the environment, their biology adapting to a world saturated with consumption energy. Senses tuned to mana frequencies. Metabolisms that drew supplementary energy from ambient flows. Neural pathways that processed consumption data alongside traditional sensory input.
In the dead channel, all of that went dark.
The column's pace slowed. People stumbled more. Spatial awareness degraded, the consumption-sensing that most of them relied on for peripheral navigation wasn't receiving input, and their visual acuity in the bioluminescent-free darkness of the dead channel was insufficient to compensate. Yejun's fighters, trained and disciplined, maintained their positions through muscle memory and verbal communication. The civilians struggled. Children cried. Adults walked with one hand on the wall, touching stone that told them nothing.
Mun was the exception. The scout moved through the dead channel with the same fluid competence that characterized everything Mun did, the oversized black eyes gathering whatever photons existed, the modified body navigating by physical sensation rather than consumption sensing. Mun had scouted beyond the Warrens' mana-rich zone before. Had spent time in passages where the flows thinned to nothing. The consumption silence was familiar territory for the scout, and Mun's body language, relaxed, confident, the movements of someone who knew this road even if they'd never walked this specific stretch of it, provided the column with something that Raze's tactical briefing hadn't: visible proof that survival in silence was possible.
The Warrens residents had it worst.
Twenty years in a mana-rich junction point. Twenty years of consumption energy saturating every surface, every breath, every moment of biological existence. Their modifications were the deepest, not just the surface changes of the column's members, but fundamental biological restructuring built on the assumption of constant ambient mana. Their metabolisms ran on it. Their sensory systems were calibrated to it. Their bodies had evolved in partnership with the Warrens' consumption environment the way deep-sea fish evolved in partnership with pressure.
Remove the pressure, and the fish dies.
The Warrens residents weren't dying. But they were struggling. Their movements became stilted, the graceful, frequency-coordinated motion that characterized their group behavior in the settlement replaced by individual, disconnected stumbling. Their frequency-language degraded, the consumption-based communication system that they relied on for social coordination losing resolution as the ambient energy that carried their signals disappeared. They could still transmit, but the range dropped. Meters instead of tens of meters. Whispers instead of conversation.
They clustered. The nineteen pulling closer together, their modified bodies seeking the proximity of compatible consumption signatures, the biological equivalent of huddling for warmth. The clustering slowed the column. Yejun's march formation, designed for single-file efficiency, couldn't accommodate a knot of nineteen bodies moving as a unit through a passage that was four meters wide in places and two meters wide in others.
The integration friction that had been manageable in the Warrens became acute in the dead channel. Two groups with different movement patterns, different sensory dependencies, different responses to environmental stress, crammed into a tunnel with no room for the social buffer zones that made coexistence work.
Raze kept his hands on the walls. Both palms, pressing against the basalt as he walked, reading the stone's physical structure for the geological features that would guide them. Fault line orientation. Mineral composition gradients. The subtle density variations that indicated proximity to a geological node, a point where the dead channel intersected a live flow.
Navigation by absence. Finding their way by sensing what wasn't there and inferring the shape of what was.
---
The first crisis came four hours in.
Goh materialized beside Raze without a sound. Her modified body moved through the dead channel with less difficulty than her residents, the brown eyes gave her an advantage, the human visual system providing spatial data that pure consumption sensing couldn't match in the absence of mana. But her face was tight. The thin mouth compressed into a line that Raze's beast instinct read as controlled alarm.
"The container," she said.
Raze's material-sensing shifted to the amber shell against Goh's chest. The living container that held the cracked seed, the biological support system grown from the garden's organisms, attuned to the seed's consumption signature, designed to maintain minimal metabolic requirements during transport.
Designed for a mana-rich environment.
The container's respiratory rhythm had slowed. The expansion-contraction cycle that Raze had watched synchronize with the seed's damaged pulse was losing tempo, the intervals between breaths stretching, the amplitude decreasing, the living membrane's metabolic activity declining as the ambient energy it drew from its surroundings fell to zero.
The dead channel had no ambient consumption energy. The container, which sustained itself by drawing mana from its environment the way a plant drew carbon dioxide from air, was suffocating.
"How long?" Raze asked.
"The membrane's metabolic reserves will sustain the seed for approximately six hours at current depletion rate. After that, the container's cellular structure begins to fail. The membrane loses coherence. The seed is exposed."
Six hours. They'd been in the dead channel for four. The next geological node, the point where the dead channel intersected a live flow, was, based on Raze's material-sensing, approximately three hours ahead at current pace.
"We need a flow contact," Goh said.
"The next node is three hours out."
"The container won't last three hours at this rate. The depletion is accelerating, the membrane's cells are burning reserves faster as the ambient energy drops below their minimum threshold. Two hours. Maybe less."
The plan's first contradiction, exposed in the simplest possible terms. The dead channels hid them from the Ancient One's sensing. The dead channels also starved the one thing they were trying to protect. Every hour of safety for the column was an hour of death for the seed.
"Can you sustain the container directly? Feed it consumption energy the way you fed the garden?"
"I've been feeding it since we entered the dead channel. My reserves are the reason it's lasted this long." Goh's brown eyes were steady, but the statement carried the specific weight of someone disclosing the extent of a problem they'd been managing alone. "I can't sustain it indefinitely. My own metabolism requires ambient energy. In the dead channel, I'm burning my reserves to keep the container alive while my body burns reserves to keep me alive. I'm losing both accounts simultaneously."
Double depletion. The container eating Goh's energy. Goh's body eating its own reserves. Two organisms starving in tandem, the woman keeping the seed alive at the cost of her own metabolic stability.
Raze looked ahead. The dead channel stretched into darkness, featureless, silent, the geological fault line cutting through basalt that offered no ambient energy, no consumption support, no life. Three hours to the next node. Two hours until the container failed.
"We move faster," he said.
"The column can't move faster. The Warrens residents—"
"Then I go ahead. Alone. I find the node, I tap the flow, I bring ambient energy back to the container."
"You can't carry ambient energy. It's not a substance, it's a field. It exists where the flows are and doesn't exist where they aren't."
"Then I bring the container to the flow."
Goh looked at him. The brown eyes calculating, the woman who'd spent twenty years learning that hasty solutions to biological problems created worse problems than the ones they solved.
"You want me to give you the seed."
"I want you to let me run ahead with it. Find the node. Feed the container from the live flow. Return."
"The live flow carries the Ancient One's signature. You know this. Jin told you."
"A brief contact. Seconds. The container feeds, I read our bearing, I pull back before the wake propagates."
"And if the wake propagates faster than you expect? If the Ancient One's probing has reached this region? If a brief contact is enough for it to localize our position?"
"Then we have a problem either way. Because if the container fails, the seed is exposed, and we're carrying a dead organism through a dead tunnel with no reason to keep running."
Silence. The dead channel's specific, total silence, the absence of consumption energy, the absence of the deep network's constant subsonic hum, the absence of everything that made the underground feel alive.
Goh unstrung the sling.
The amber container came away from her chest with a separation that Raze's beast instinct recognized as physical pain, not contact pain, not injury, but the pain of disconnection. Goh had been carrying the seed against her body for four hours, her consumption signature feeding the container through direct contact, the living membrane attuned to her frequency. Removing it was severing a biological connection.
She handed it to him. The container was warm. Alive. The respiratory rhythm slow but present, the expansion-contraction barely perceptible against his palms. Through the amber membrane, the cracked seed was visible. Dark. The fracture line wider than he remembered, or maybe that was the light.
"The membrane responds to consumption energy intensity," Goh said. "Feed it the way you'd feed a candle, steady, low, controlled. Not the way you fed the seed in the garden. If you push too much energy through the membrane, the cells rupture and the container fails instantly."
A candle. Not a furnace. The lesson, again. Always the lesson.
"I'll be back before the column reaches the node."
Goh nodded. The brown eyes watched him go with an expression that his beast instinct couldn't classify, somewhere between trust and resignation, the face of a woman handing the most important thing in her life to the man who'd already damaged it once.
Raze ran.
---
The dead channel compressed as he moved away from the column. The fault line narrowed, four meters to three, three to two and a half, the geological feature tightening as it approached the intersection with whatever structure carried the live flow. The ceiling dropped. His spinal ridge scraped stone. The scales on his forearms caught against the walls as he ran through a passage built for geology, not for people.
He held the container against his chest the way Goh had held it. The amber membrane pulsed against his shirt, faint, fading, the respiratory rhythm of a living organism running out of the energy it needed to stay alive. His consumption signature leaked through his hands and into the container's surface. Not intentionally, the ambient field that his body produced, the kin-field compressed to nothing but not eliminated, the baseline consumption output that every modified organism generated simply by existing. The container's cells absorbed what he offered. Not enough. The depletion continued.
His material-sensing tracked the geological features ahead. The dead channel was approaching something, the mineral composition of the basalt shifting, the quartz intrusion that sealed the passage from the live flow thinning. The node was closer than his initial estimate. Not three hours at column pace. Maybe forty minutes at his pace. The geological intersection where dead stone met living current, where the flow would provide what the container needed.
He pushed harder. The tunnel narrowed further. He turned sideways to fit through a section where the fault walls pressed within a meter of each other, the container held above his head to clear the constraint, his body squeezing through stone that had last been navigated by mana flows and mineral deposits.
The node.
He felt it before he reached it, the material-sensing detecting the transition from dead stone to live current the way ears detected the transition from silence to sound. A boundary. A line in the basalt where the sealed quartz ended and the open geological structure began. Beyond the boundary, mana. The consumption energy flowing through the deep network's circulatory system, humming through the stone with the constant, subsonic vibration that meant life and connection and the Ancient One's three-hundred-year-old fingerprint woven into every frequency.
Raze stopped at the boundary. Pressed his palm against the quartz seal. Thin here, centimeters, not meters. The seal that separated dead channel from live flow was a membrane of mineral deposit, translucent to his material-sensing, the mana flow visible beyond it like light through frosted glass.
He could feel the flow. Rich. Dense. The consumption energy concentrated at this geological node, a point where multiple flow channels converged, the mana intensity higher than the ambient levels he'd sensed at the Warrens. A junction. Not a major one, not the kind of confluence that would support a settlement, but a node where the deep network's circulation concentrated enough to sustain organisms and provide navigation data.
The Ancient One's signature was in the flow. Raze's ancient core recognized it, the three-hundred-year-old consumption fingerprint, woven into the mana current like dye in water. Passive. Ambient. The background presence of a predator whose territory extended through the geological substrate that carried the flows.
But something else was in the flow. Something that hadn't been there when Jin had described the signature hours ago in the Warrens.
Pulses. Regular. Rhythmic. Consumption energy signatures traveling through the mana flow with the deliberate cadence of intentional transmission. Not the ambient background of a predator's centuries-old presence. Active probing. The Ancient One was sending feelers through its network, sonar pulses, consumption-based search signals riding the mana flows through the deep network's channels.
Searching. For them.
The tracker had transmitted. The Ancient One had received data on the Warrens, on the garden, the seed, the junction point, the hundred and twenty consumption signatures that had been congregating in its territory. And now it was looking. Not with chimeras, not yet. With its own signature, pushed through the flows like radar pulses through water, each pulse carrying the search parameters of a predator that knew what it was hunting and was methodically sweeping its sensory network for the disturbance that a hundred and twenty fleeing organisms would create.
The pulses passed through the node at intervals. Raze counted. Every forty seconds. A sweep. The consumption signature washing through the mana flow, sampling the ambient field for anomalies, displacement, disturbance, the wake that bodies moving through mana-saturated stone would produce. Each pulse originated from the north-northeast. From the Ancient One's territory. From the organism that was three hundred years old and patient and intelligent and had just lost sight of a hundred and twenty mice in its walls.
The container pulsed against his chest. Fading.
He couldn't wait for the probing to stop. It wasn't going to stop. The Ancient One would search until it found them or decided they were gone, and based on everything Raze knew about the predator's patience, it wouldn't decide they were gone for a long time.
He had to feed the container. He had to touch the live flow. He had to do it between the probe pulses, in the thirty-eight-second window between sweeps, and he had to do it without creating a wake large enough for the next pulse to detect.
Raze counted. Pulse. The consumption signature washed through the node, sampling, searching. The signature dissipated as it passed. Thirty-eight seconds until the next one.
He broke the quartz seal.
Devour ate through the mineral deposit in three seconds, the quartz dissolving under the consumption attack, the thin barrier between dead channel and live flow failing like a dam breached at its narrowest point. Mana flooded through the opening. The consumption energy hit his body and his material-sensing and his ancient core simultaneously, and the sensation was relief. Physical, visceral, the relief of breathing after holding your breath, the 147 integrated consciousnesses drinking the ambient energy like water after four hours of drought.
He shoved the container into the flow.
The amber membrane's cells responded instantly. The living tissue absorbing mana from the current, the respiratory rhythm accelerating from its death-crawl to something approaching normal, the container's biological systems reigniting as the energy they needed became available. Through the amber shell, the seed's pulse strengthened. The fracture line didn't change, still dark, still visible, still the record of Raze's mistake, but the consumption signature around it stabilized.
Seconds. He counted. Five. Ten. The container feeding. His material-sensing reading the flow, direction, intensity, concentration gradient. The nearest major junction was southeast, confirming his earlier mapping. Distance, his sensing couldn't be precise through a brief contact, but the flow's intensity gradient suggested thirty-plus kilometers.
Fifteen seconds. The container's respiratory rhythm was approaching normal. The membrane's cells were saturating, absorbing mana at a rate that would sustain them for hours in the dead channel. Maybe six hours. Maybe eight. Enough to reach the next geological node, if the column moved at reasonable speed.
Twenty seconds. Pull back. The window was closing. Eighteen seconds until the next probe pulse swept through the node and sampled the mana field for disturbances.
Raze pulled the container from the flow.
The wake hit.
He felt it propagate. His material-sensing tracked the disturbance as it radiated from the breach point, the disruption created by his body and the container's sudden presence in the live flow, the displacement of mana around two foreign objects in a current that had been flowing undisturbed. The wake traveled outward through the flow channel. North. South. East. Following the mana's path through the geological substrate, carrying the evidence of their contact.
How far? How fast? The disturbance attenuated with distance, the signal degrading as it propagated through stone, losing resolution, losing definition. At some distance, the wake would fade below the noise floor of the ambient flow. At some distance, it would become undetectable even to the Ancient One's probing.
But he didn't know what that distance was. And the next probe pulse was coming in, twelve seconds. If the pulse reached the node before the wake dissipated, the pulse would sample the disrupted flow and carry the anomaly back to the Ancient One like a message in a bottle.
Raze sealed the breach.
Not with quartz, he didn't have quartz. With stone. His Devour ability, reversed, not consuming material but pushing consumption energy into the basalt around the breach point, forcing the stone to compress, to fill the gap, to create a seal that was crude and uneven but physically solid. The breach closed. The mana flow cut off. The dead channel's silence returned.
The container breathed against his chest. Steady. Sustained. The amber membrane's cells were full, saturated with mana, the respiratory rhythm strong enough to sustain the seed for hours.
But the wake was still out there. Still propagating. And in, he counted, three seconds, the next probe pulse would sweep through the node and sample the flow for exactly the kind of disturbance that a twenty-second contact had created.
Three.
Two.
One.
The pulse passed through the stone beyond the seal. Raze felt it through his material-sensing, the Ancient One's consumption signature sweeping the mana flow on the other side of his crude barrier. Sampling. Searching. The probe pulse encountered the flow, read its composition, analyzed its patterns.
The wake. Had it dissipated? Had twenty seconds of contact created a disturbance small enough to fade below detection threshold in the twelve seconds before the pulse arrived?
Raze didn't know. The seal blocked his sensing, he couldn't read the flow's state on the other side of the barrier he'd created. He stood in the dead channel's silence with the container breathing against his chest and the sealed node at his back and no way to determine whether the Ancient One had just received confirmation that something was in its dead channels.
He ran back.
---
The column was where he'd left it. Slower than before, the Warrens residents' metabolic strain was visible now, the deeply modified bodies moving with the stiff, conservation-mode gait of organisms reducing their energy expenditure to survival minimum. The couple's child was being carried by her father, the six-fingered hands holding the small body against his chest, the crystal fox clutched in the child's fist pressing its geological colors into the father's shoulder.
Goh met him at the column's head. He handed her the container. She pressed it against her chest, the living membrane reconnecting with her consumption signature, the biological bond reestablishing through contact. Her brown eyes registered the container's improved state: the strong respiratory rhythm, the saturated cellular reserves, the seed's stabilized pulse visible through the amber shell.
"The flow is active," Raze said. "The Ancient One is probing. Consumption-based search pulses through the mana channels. Every forty seconds."
Goh's expression didn't change. The information landed and was processed without the intermediate step of reaction, the response of someone who'd spent twenty years anticipating the worst and was now confirming its arrival.
"Can we navigate around the probes?"
"Maybe. The dead channels block them, the probes travel through live flows only. But every time we need to touch a live flow, for navigation, for the container, we create a detectable disturbance."
"How detectable?"
"I don't know. I sealed the breach after twenty seconds of contact. The wake may have dissipated before the next probe. Or it may not have."
Jin appeared from the column's interior. The empath's face was drawn, the consumption silence was harder on her than on most, her sensitivity to ambient energy making the dead channel feel like a sensory wound. But her eyes were focused.
"I felt the contact," she said. "From here. The moment you breached the seal, I felt the mana flow flood through the gap. If I could feel it from three hundred meters—"
"The Ancient One could feel it from further."
"Maybe. Probably. The question is resolution. Could it tell what we are from that contact? Location, yes, it knows something disturbed the flow at that node. Direction of travel, possibly, the wake would carry directional data. But specifics, how many of us, what we are, where we're going? That depends on how much data the probe pulse captured before the wake dissipated."
The column waited in the dark. A hundred and twenty people standing in a dead channel, listening to three people discuss whether the predator hunting them had just received their coordinates.
"We keep moving," Raze said. "Faster. The next node is approximately two hours ahead at accelerated pace. We need to reach it before the container's reserves deplete again."
"And at the next node?"
"Same procedure. Brief contact. Feed the container. Read our bearing. Seal the breach."
"And create another detectable disturbance."
"Yes."
The arithmetic was brutal. Every six to eight hours, the container needed feeding. Every feeding required contact with a live flow. Every contact created a wake. Every wake was a potential signal to the Ancient One. They couldn't hide without starving the seed. They couldn't feed the seed without revealing themselves.
The dead channel strategy hadn't failed. It had revealed its cost.
---
An hour into the accelerated march, Seo collapsed.
Raze didn't know Seo's name until afterward. One of the Warrens' nineteen, a man whose modifications had progressed further than most, the original human form so deeply restructured that the body had become dependent on ambient consumption energy for basic metabolic function. Not a choice. Not a failure of will. The biological reality of an organism that had adapted to an energy-rich environment so thoroughly that removing the energy was removing a requirement for life.
Seo's consumption system failed first. The internal processes that regulated mana distribution, the biological network that drew ambient energy from the environment and distributed it to organs that required consumption-based sustenance, hit empty. The system had been running on reserves since they entered the dead channel. Four and a half hours of reserves, burned through by a metabolism that had no low-power mode because it had never needed one.
The failure cascaded. Without consumption-based sustenance, Seo's modified organs began shutting down in order of expendability. Peripheral sensing went first, the consumption-sensitive arrays that the Warrens residents used for spatial awareness going dark, the biological sensors powering down to conserve energy for critical systems. Then the frequency-language transmitters, the organs that produced and received the consumption-based communication signals, shutting off because communication was less important than survival.
Then, as the metabolic crisis deepened, Seo's body did what stressed biological systems do: it panicked.
The discharge was involuntary. A burst of consumption energy released from Seo's core systems, the biological equivalent of a muscle spasm, an uncontrolled contraction of the energy network that pushed a pulse of consumption signature outward through the man's body and into the surrounding stone.
In the Warrens, the pulse would have been absorbed by the ambient field. Background noise in a noisy environment. Invisible.
In the dead channel, the pulse was a gunshot in a library.
Raze felt it through his material-sensing. A spike of consumption energy radiating from Seo's collapsed body through the dead basalt, the signal propagating through stone that had carried nothing for millennia, the pulse traveling along the old geological features with the clarity of a bell struck in vacuum. The signal reached the nearest geological boundary, the sealed quartz that separated the dead channel from the live flow network, and some of it passed through. Not all. The seal attenuated the signal. But quartz wasn't perfect insulation, and Seo's involuntary discharge was strong, the desperate output of an organism in crisis.
The pulse entered the live flow.
Raze felt it happen. The consumption signal crossing from dead stone into living current, joining the mana flow, becoming part of the data stream that the Ancient One's probing swept every forty seconds.
Not a wake this time. Not the subtle displacement of a brief contact carefully managed. A signal. A clear, distinct consumption signature, originating from a location that should have been empty, broadcasting through a sealed geological feature that should have been silent.
A ping. Announcing their approximate position to anything listening.
The column stopped. Seo lay on the tunnel floor, body rigid, the involuntary discharge subsiding as the consumption system exhausted itself. Two of the Warrens residents knelt beside him, their modified hands pressing against his body, their consumption signatures, weakened by the dead channel but not yet depleted, feeding energy directly into his failing systems. Emergency transfer. The biological equivalent of mouth-to-mouth resuscitation, one organism sustaining another through direct energy sharing.
Goh was there. The container against her chest, the seed breathing its sustained rhythm inside the amber shell. Her brown eyes on Seo, then on Raze. The look carrying a question that wasn't a question.
"How bad?" she asked.
Raze's palms were on the wall. Material-sensing at full extension, tracking the pulse's propagation through the quartz seal, through the live flow, into the deep network's circulation. The signal was weakening with distance. Attenuating. But the next probe pulse—
He counted.
The probe swept through the live flow beyond the seal. The Ancient One's consumption signature washing over the region where Seo's involuntary discharge had entered the current. Sampling. Analyzing.
Raze couldn't tell what the probe read. He couldn't tell whether the pulse had dissipated enough, whether the signal had degraded below the noise floor, whether the Ancient One's three-hundred-year-old sensing apparatus was precise enough to distinguish a metabolic crisis discharge from the random fluctuations of geological energy transfer.
He couldn't tell.
That was the worst part.
"We move," Raze said. "Now. Faster."
"Seo can't walk."
"Then we carry him."
Two of Yejun's fighters lifted the collapsed man between them. Seo's body was light, the deep modifications had reduced his mass, the consumption-based metabolism replacing dense muscle and bone with lighter, more efficient biological structures. The fighters slung his arms over their shoulders and started walking.
The column moved. Faster than before, the urgency transmitted through body language and murmured words and the tight, compressed silence of people who understood that something had gone wrong and that the response was speed. The Warrens residents who could still walk did so with the grim determination of organisms conserving their final reserves. The column's members supported those who faltered, hands on arms, shared packs, the physical solidarity of people who'd been through enough together to skip the negotiation phase of mutual aid.
Jin fell into step beside Raze at the head of the column.
"How many of Goh's people are close to Seo's state?"
"I can feel three more on the edge. Their metabolic signatures are fluctuating, the same pattern Seo showed before the collapse. They'll last longer than he did, their modifications aren't as deep, their dependence on ambient energy isn't as total. But hours, not days."
Three more. Out of nineteen Warrens residents, four would require metabolic support before they reached the next node. Four people whose bodies would demand consumption energy that the dead channel couldn't provide, and whose involuntary discharges would send signals into the live flow network every time their systems reached crisis.
Every six to eight hours: a flow contact for the seed.
Every few hours after that: a metabolic crisis discharge from a Warrens resident.
The dead channel wasn't just hiding them. It was killing them. Slowly, steadily, the consumption silence stripping away the biological infrastructure that the most deeply modified members of their group depended on for survival. The longer they stayed in the dead channels, the more of Goh's people would fail. The more who failed, the more involuntary discharges. The more discharges, the more signals in the live flow.
The dead channel strategy was eating itself.
Raze's material-sensing tracked the tunnel ahead. The next geological node was close, ninety minutes at their current accelerated pace. A brief contact for the container. Navigation data. Metabolic support for the failing Warrens residents.
And another detectable disturbance in the Ancient One's sensory network.
Behind them, somewhere in the live flow channels that threaded through the stone like veins through flesh, the forty-second probe pulses continued their sweep. Searching. Patient. The rhythm of a predator that had been alive for three centuries and knew that prey, eventually, had to move.
Raze kept his hands on the walls and walked into the silence, and the silence walked with him, and neither of them pretended it would last.
