Kraken Made: Below the Window

The first thing the Window did was touch Sana’s ribs.

Not hard. Not enough to move her. The pressure reached through the suit as a broad, low compression, passed across the rigid chest shell, and settled beneath her sternum with the intimacy of a hand laid flat against bone.

Her instruments registered it half a second later.

A pale waveform climbed across the lower edge of her visor display, crested, then thinned into diagnostic noise.

Sana kept her left glove against the ledge and counted.

One.

Suspended sediment moved through her helmet lamps in slow silver drifts. Beyond it, the fissure descended at an angle too steep for her light to follow. The surrounding rock was black basalt veined with paler mineral deposits, each surface sharpened by the hard white illumination of the survey lamps.

Two.

Her umbilical rose behind her in a lazy curve, its outer jacket striped with reflective bands. It crossed the ledge, passed through the relay frame, and continued upward into darkness toward the survey bell.

Three.

Rodger worked eleven meters to her right, securing the secondary sensor mast against a ridge that had rejected two anchors and blunted one drill bit. His helmet lamp moved whenever he bent, turning the surrounding water into a shifting architecture of stone, cable, and pale particulate.

Four.

Sana’s right thumb tingled inside the glove.

Five.

The sensation had nothing to do with the pressure wave. It belonged to an older injury, one she understood and therefore preferred. Cold had damaged the nerves in three fingers during a failed joint-heater cycle eighteen months earlier. They worked. They simply lied to her about temperature and occasionally forgot how firmly they were holding things.

Six.

The relay frame’s status lights remained green.

Seven.

Ward breathed quietly over the shared channel from the bell. Sana could hear the soft scrape of equipment somewhere near his console and the intermittent hum of a ventilation fan that needed a new bearing. The sound was faint, ordinary, and human.

Eight.

Rodger grunted as his anchor driver kicked back.

Nine.

Sana’s suit logged the dying edge of the pressure event.

Ten.

Nothing moved.

Eleven.

The second pulse arrived.

It entered her body before the waveform appeared.

Sana watched the display catch up.

“Still exactly eleven,” she said.

Rodger stopped wrestling the anchor driver long enough to turn his helmet toward her. “You planning to announce every one?”

“Until Ward admits his timer is drifting.”

“My timer is synchronized to the bell’s master clock,” Ward said. “Unlike the private counting system occurring inside your head.”

“Eleven-point-zero-two seconds.”

“Eleven-point-zero-one-eight.”

Sana smiled despite herself. “So it is drifting.”

A pause followed.

Ward said, “I regret giving either of you access to telemetry.”

“You regret staffing the dive with literate people,” Rodger said.

“I regret several career decisions. Most of them have names.”

Sana looked up instinctively, though the bell lay far beyond the reach of her lights. Its signal reached them through the umbilicals, reduced by depth and rock interference but still carrying voice, data, power, heated fluid, and the invisible machinery of survival.

The cable at her back was thick enough to look industrial and flexible enough to disappear from awareness when it behaved. Gas, heat, power, voice, and telemetry travelled through separate lines braided into one black jacket. In training they had called it a diver’s artificial organ. Sana had considered the phrase melodramatic until a kink once cooled her fingers before the warning appeared.

She felt the Window’s pulse the same way now.

Body first.

Machine second.

The order bothered her more than the pressure itself.

“Flow temperature?” Ward asked.

Sana checked. “Nominal.”

“Joint heaters?”

“Nominal.”

“Rodger?”

“Emotionally wounded. Mechanically perfect.”

“Your left elbow is running three degrees below Sana’s.”

Rodger glanced at the joint readout. “Mechanically adequate.”

“Cycle it.”

“I’m holding a drill.”

“Then put down the drill.”

Rodger looked toward Sana as though she might overturn the command.

She said, “I support Ward’s rare flirtation with wisdom.”

“Betrayal at depth.”

He magnetized the anchor driver to the ledge, flexed his left arm twice, and waited while the joint heater restored circulation. The movement made his umbilical sway behind him. The cable passed through a separate guide in the relay, close enough to Sana’s that their reflective bands crossed when the water shifted.

Two lives ran through the same frame.

Sana checked its anchors again.

Anchor one carried twelve percent of rated load. Anchor two carried nineteen. Anchor three sat at eleven. Anchor four, Rodger’s personal enemy, fluctuated between eight and nine as the mineral crust beneath its foot compressed.

All within margin.

The ledge beneath them was wide by trench standards, but its outer edge dropped into a fissure no autonomous vehicle had mapped cleanly. Successive sonar passes suggested a slope, a sheer descent, and overlapping surfaces the software dismissed as reflection. The planners had approved a human survey before the contract window closed. Sana had signed because the hazard multiplier would erase three months of certification debt. Down here, practicality had acquired a pulse.

“You’re quiet,” Rodger said.

“I’m counting.”

“You were talking while counting before.”

“Then I’m improving.”

Ward said, “Please do not encourage her to multitask.”

“I was checking whether she’d gone contemplative.”

“I don’t have that certification,” Sana said.

“You can borrow mine.”

“Yours expired.”

Rodger returned to the sensor mast. “Cruelty travels beautifully through hard line.”

Sana pictured Ward in shirtsleeves at the main console, one hand wrapped around a cup he would have forgotten to drink. Behind him would be the narrow equipment racks, the fold-down seats, the tool cases locked beneath webbing, and the pressure hatch leading into the transfer compartment. Somewhere in the aft locker, if Rodger had not stolen it, was the peach Sana had brought down for after the dive.

She had spent too much money on it.

The fruit had been imported to the offshore platform in a refrigerated shipment that arrived twice a month and sold out in ten minutes. Sana had bought one because she had worked sixteen consecutive days and decided that adulthood ought to include the right to make one bad financial decision that bruised easily.

Rodger had mocked her until she threatened to invoice him for half.

He had tried to steal it while she sealed her neck ring, claiming he was inspecting it for pressure integrity. Ward had ordered him to return it without looking away from the console. The peach now waited in the bell’s cold compartment, absurdly protected while Sana stood beneath more water than any fruit had reason to imagine.

She intended to eat it with juice running over her knuckles, climb into dry clothes, and call the lender about the rehabilitation debt attached to her right hand. The hazard bonus would erase three months of it. The hand itself had cost more to repair than it had earned the year before the injury.

Sana flexed the damaged fingers inside the glove.

Thumb.

Index.

Middle.

All functional.

The future waited above them with bills, bad laundry, Ward’s cold coffee, Rodger’s theft attempts, and one expensive peach. It waited with the confident patience of something that had never once doubted its own arrival.

The dive would end. The bell would rise. Ward would complain about their documentation. Rodger would try again to steal the peach.

None of it felt urgent.

Sana released the ledge and shifted her weight onto the suit’s magnetic boot plates.

“Window Station, Survey One,” she said. “Pulse interval confirmed stable. No visible displacement following event twenty-three.”

“Copy,” Ward replied. “Relay strain?”

Rodger glanced toward the frame. “Within margin. Anchor four is pretending it has integrity.”

“Is that a technical assessment?”

“It’s a personal dispute.”

Sana checked the relay data herself. The frame had been installed across the narrowest stable section of the ledge, where three basalt projections provided mechanical purchase and the fourth leg compensated for uneven rock. Its central housing managed both umbilicals, amplified local telemetry, and supported the remote sensor array they had spent most of the dive positioning.

Every displayed load remained beneath tolerance.

Barely, in two cases.

She expanded the structural overlay and compared the current values against the installation record. Anchor two had gained two percent since placement. Anchor four had lost less than one. The differences could come from sediment compression, changing line angles, or the broad pressure events travelling through the ledge.

None of the changes met an abort threshold.

Sana marked them anyway.

“Anchor two trending upward,” she said.

Ward opened the same data. “Within expected settling.”

“Expected by whom?” Rodger asked.

“The people who signed the procedure you pretended to read.”

“I read the bold portions.”

“You highlighted the bold portions.”

“That’s a form of engagement.”

Sana smiled again, and the ordinary movement of her face inside the helmet made the trench seem briefly smaller.

The site had resisted easy classification since the first autonomous probe descended through the fissure six months earlier. Sonar suggested a continuous drop beneath the ledge, but returned inconsistent distances from the lower surfaces. Water samples showed elevated mineral content without the temperature signature expected from active vents. The pressure events repeated every eleven seconds, regular enough to resemble machinery and broad enough to disturb sediment across hundreds of meters.

No seismic model accounted for them.

No known animal produced them.

The first three probes had recorded the pulses. The fourth had discovered the Window.

Sana turned toward the pale surface embedded in the rock ahead of her.

It occupied a shallow recess along the inner wall of the fissure, fourteen meters across at its widest visible point and perhaps twice that beyond the current survey lamps. Its edges disappeared beneath mineral crusts and folded stone. In the central area, the material was translucent enough for her light to enter, but not clear enough to reveal what lay behind it.

The survey team had called it the Window before deciding whether it was mineral, ice, biological film, or an unknown composite.

The name had survived every formal objection.

Sana had seen enough project language to know why. Technical terms gave things boundaries. The Window had resisted all of them.

---

“Pulse twenty-four approaching,” Ward said.

Sana braced lightly.

The pressure touched her ribs.

A moment later, the membrane changed.

Not much.

A faint opacity passed through it from left to right, like a cloud moving behind thick glass. Sana leaned closer. Her lamp reflection floated on the surface, distorted across subtle ridges that had not appeared in the preliminary scans.

“Rodger.”

“I see it.”

The opacity faded before his helmet turned fully toward it.

Sana saved the preceding thirty seconds of visual feed.

“Possible internal transmission,” she said.

“Specify,” Ward replied.

“I can’t. A change in density or reflectivity moved across the sample face during the pulse.”

“Local sediment?”

“No exterior plume.”

“Lamp angle?”

“Fixed.”

Rodger finished securing the sensor mast and tugged twice on its housing. “I had something similar on my side three pulses ago. Thought it was my light.”

Sana looked toward him. “You didn’t report it.”

“I was waiting to find out whether my light had developed a personality.”

“Your light would request reassignment.”

“It would miss me.”

Ward broke in before Rodger could continue. “Both feeds marked. Sana, proceed with surface inspection only. No penetration until the classification sweep finishes.”

“Copy.”

She released the boot magnets one at a time and crossed the ledge.

The suit translated her movements into slow, heavy gestures. It was not designed for swimming so much as negotiating an environment that would otherwise compress her body past survivability. Rigid shell sections protected her torso and helmet. Layered flexible joints allowed limited reach at shoulders, hips, knees, and ankles. Small maneuvering thrusters could correct position in open water, but every sustained movement depended on leverage, patience, and a clear understanding of where several hundred kilograms of equipment intended to go next.

Sana preferred rock beneath her boots.

Rock could fail, but at least it admitted that it was there.

The Window’s surface waited six meters ahead.

She passed the relay frame, ducking beneath the crossed lines. Its housings were dusted with fine sediment. Status bars glowed green behind protective covers. Each umbilical fed through a motorized guide designed to reduce side-loading if either diver moved along the ledge.

Rodger’s line shifted as he approached behind her.

“Give me room,” Sana said.

“I am giving you room.”

“Your shoulder is in my light.”

“That’s companionship.”

“We also call that occlusion.”

Ward said, “Rodger, remain clear of the sample area.”

“You hear that? He called me Rodger. This is serious.”

Sana felt another pulse before the countdown appeared.

The pressure moved through her chest and along her lower ribs. Her body had begun anticipating it, tightening a fraction of a second before contact. She tried to stop doing that.

Anticipation only made the touch feel personal.

Her right boot settled against a sloped section of stone near the Window’s lower edge. She engaged the magnets and tested the hold twice. The left boot found a shallow mineral shelf. With both feet anchored, she leaned close enough for the suit’s contact array to extend.

The array touched the translucent material.

Numbers populated her display.

Surface temperature near ambient.

No meaningful electrical discharge.

Elastic response inconsistent across the probe head.

Trace organic compounds.

High silica content.

Minute internal movement.

The classification system produced three possible categories, erased two, restored one, then marked the entire assessment as low confidence.

“Helpful,” Sana murmured.

Ward heard her. “Results?”

“It believes the Window is mineral, biological, or sensor contamination.”

“So the machine agrees with the team.”

Sana adjusted the contact pressure.

The surface yielded.

Not deeply. Less than two millimeters. Yet the movement did not resemble a loose sediment coating or brittle mineral film. The resistance increased gradually, then held her probe at a fixed depth.

She reduced force.

The material returned to its original position.

“Elastic,” she said.

“Confirmed,” Ward replied. “Recovery time one-point-four seconds.”

Rodger moved closer despite his instruction, though he stopped outside her working radius. “You getting any layers?”

“No stable boundary.”

“What does that mean?”

“It means the density changes before the probe can decide where one material ends and another begins.”

“So layers.”

“Or a gradient.”

“Which is a polite layer.”

Sana ignored him and selected a secondary scan.

The Window received the instrument light differently from the surrounding rock. The blue diagnostic beam entered several centimeters before scattering into dimness. Yellow calibration points penetrated less deeply, remaining distinct beneath the surface before fading.

She rotated the emitter.

The blue followed internal lines she had not seen before.

They were exceedingly fine, thinner than veins in a leaf, though the comparison felt wrong as soon as it occurred to her. They intersected, separated, and continued beyond the probe’s field.

“Ward, record spectral transmission.”

“Already recording.”

“Blue wavelength is travelling laterally.”

“Refraction?”

“Possibly.”

Rodger said, “That sounded like you don’t think it’s refraction.”

“I think refraction is a word available to me.”

“Excellent scientific standard.”

She removed the probe.

The blue lines vanished with it.

Her right hand cramped as she reached for the sampler case at her thigh. The cold-damaged fingers had stiffened during the survey, despite stable glove temperature. She flexed them once, watching the joint indicators confirm movement that sensation only partially reported.

Thumb functional.

Index functional.

Middle finger delayed by less than one tenth of a second.

No grip warning.

The scar along the heel of her hand tightened inside the liner.

That injury had come from sealant rather than cold. Two years earlier, a pressure-door repair on another contract had ruptured its mixing capsule. Uncured compound flooded her glove before the emergency purge cleared it. The chemical burn had healed into a pale rope of tissue that pulled whenever she spread her hand too wide.

The sealant had looked inert until the catalyst reached it and heated around her skin faster than she could strip the glove. The memory lived in the hand more reliably than in language.

The contractor had paid for half the treatment.

The lender had covered the rest.

The lender now owned a percentage of every dangerous thing Sana agreed to do.

Ward’s voice softened by a degree. “How are the fingers?”

“Operational.”

“That wasn’t the question.”

“They’re within baseline.”

Rodger angled his helmet toward her right hand. He knew the difference between an answer and an evasion. To his credit, he did not challenge it over the shared channel.

Sana secured the case against her thigh with her left hand and used the right only for the smaller depth control. The motion took longer than it should have. She made each step deliberate enough to look procedural. Rodger saw the performance and let it stand.

Sana removed the sampling tool.

It was narrow, ceramic-edged, and designed to lift a shallow shaving without drilling through a surface. The collection channel behind the blade would seal automatically once it contained enough material for analysis.

She inspected the edge.

Clean.

She checked the depth stop.

Three millimeters.

She checked it again.

Rodger watched. “You planning to sample it or marry it?”

“Marriage has fewer safety inspections.”

“Not the ones I’ve seen.”

Ward said, “Classification sweep complete. No volatile reaction detected. Shallow sample authorized at three millimeters maximum.”

“Copy.”

Sana positioned the sampler.

The Window did not look different from this close. Its translucence contained no visible structure now that the blue diagnostic light was gone. Fine irregularities crossed the surface, too broad for scratches and too organized for random mineral growth. Her helmet lamp entered a short distance and died.

She placed the edge against it.

Her body pulled back.

The movement was small enough that neither boot released, but the suit registered the transfer of weight. Her shoulders tightened. Her wrist flexed away from the surface.

Sana stopped.

Nothing had moved.

No alarm sounded. The contact point remained smooth and pale.

Yet the response had begun before she consciously decided she disliked the cut.

Her pulse rose.

“Sana?” Rodger said.

“Fine.”

“You moved.”

“Suit balance.”

Her own explanation sounded thin.

The scar in her palm pulled against the glove liner.

She could still see the gray sealant from the earlier accident hardening around her bare skin after the purge. The material had not attacked her. It had completed the reaction it was designed to complete. Her body had merely occupied the wrong place.

The Window was not sealant.

Her wrist still held the angle of retreat.

Sana reset the sampler.

The ceramic edge touched the material. Resistance built beneath it, soft at first, then firm. The sensation travelled through the tool into her glove as a muted drag.

Not stone.

Not ice.

Not any polymer she had handled.

She applied the minimum force required to engage the blade.

The surface depressed around it.

The sampler advanced one millimeter.

A faint tremor ran into her wrist.

Two millimeters.

The Window tightened.

Sana froze.

The material had not merely resisted. It had drawn inward around the blade. The surface contracted in a widening circle, shallow at the edges and deepest at the sampling point.

“Ward.”

“I see deformation.”

“Withdraw?”

“Hold position.”

Sana’s fingers had begun shaking.

The motion remained contained inside the glove, too small to disturb the tool, but the suit translated it into flickering pressure values. Her thumb tingled so sharply that for one instant she thought the material had shocked her.

It had not.

The fear belonged entirely to her.

“Three-millimeter limit,” Ward said. “You’re at two-point-two.”

Sana breathed in slowly.

She advanced the final fraction.

The blade lifted a shaving no thicker than a fingernail.

---

The Window contracted.

The response crossed the entire visible surface at once.

There was no gradual widening from the cut. No wave moving outward at a speed Sana could track. One moment the surface lay pale and faintly ridged beneath her lights. The next it pulled tight across fourteen meters of exposed material.

The contraction snapped the sampler sideways.

Sana’s right boot held.

Her left slipped half a centimeter before the magnet caught again.

Blue light erupted beneath the Window.

It did not bloom from the sampled point. It appeared everywhere, a web of luminous threads distributed across depths the surface had not seemed large enough to contain. Some lines burned electric blue. Others remained nearly white at their centers, edged with cold color that travelled sideways faster than Sana could turn her head.

Yellow followed.

Not as threads.

Points ignited between the blue structures, small and brilliant, each surrounded by a soft golden haze. They appeared in clusters, vanished, then reappeared farther away.

The light moved beyond her lamp cone.

Sana saw it travel beneath mineral crust at the Window’s upper edge. It passed through a fold in the rock and continued outside the visible sample face. Blue racing ahead. Yellow gathering behind. Both descending into structures or distances her instruments could not resolve.

Her hand released the sampler.

The tool remained attached to her wrist by its safety line. It struck the Window and bounced away.

Sana shoved backward.

Her boot magnets disengaged out of sequence. The right released before the left. The rigid suit twisted, and she nearly went down on one knee.

Rodger caught the upper frame of her backpack.

His glove closed around a lifting rail and arrested her movement before the umbilical could tighten.

“I’ve got you.”

The words reached her through the comm.

His hand reached her through the suit.

Sana’s breath came too fast. She could hear it circulating inside the helmet, each inhalation louder than the last. Her chest shell had not changed, but the space inside it felt reduced.

The Window remained contracted.

Blue light continued into the rock.

Yellow points moved across its surface in irregular groups.

The shallow cut had already closed.

No, not closed.

There was no visible wound.

The material beneath the sampler point had drawn together so completely that Sana could not find where the blade entered.

“Survey One, status,” Ward said.

Sana opened her mouth.

Nothing came out.

Rodger’s grip tightened against the rail. “She’s stable. Both boots secure. No suit warning.”

“Sana, confirm.”

She looked at the sampler hanging beside her right wrist.

A translucent fragment rested inside the sealed collection channel.

It glowed blue along one edge.

Yellow light pulsed once inside its center.

Sana’s stomach turned.

“I’m intact,” she said.

Her voice sounded almost normal.

Only the slight break between words betrayed the shaking in her hands.

“Any breach?”

“No.”

“Electrical contact?”

“No discharge indicated.”

“Pain?”

“No.”

That answer, at least, was true.

Ward exhaled. “Hold position. Do not make a second contact until we review.”

Rodger remained behind her. He had not removed his hand.

The blue lines dimmed gradually.

Yellow persisted longer. A few points appeared near the lower edge of the Window, vanished beneath stone, then reappeared somewhere outside Sana’s visible field.

The relay chimed.

A telemetry packet had failed checksum and requested retransmission.

Ward silenced the alert.

“Receiving sample channel,” he said. “Composition pending.”

Sana forced her right hand around the tether line and reeled the sampler in. The motion felt clumsy. Her fingers knew how to close, but the rest of her body did not trust them.

Rodger said quietly, “You all right?”

“I said I’m intact.”

“That was for Ward.”

Ward replied, “Ward is still on the channel.”

“I know.”

“Then perhaps stop discussing me as a weather condition.”

Rodger ignored him. “You pulled away before it moved.”

Sana looked at the Window.

The contraction had begun after the cut.

Her recoil had not.

“I shifted my balance.”

“No.”

“Rodger.”

He let the silence hold for a moment.

Then his glove eased away from her backpack rail. He remained close enough to catch her again.

The absence of his hand was immediate. Her suit had not needed the support once both boots locked, yet her body noticed the pressure leaving and leaned after it by a fraction.

Sana corrected before the movement became visible.

Ward said, “Sample composition is unstable.”

“Meaning?” Sana asked.

“Meaning the analyzer is rerunning.”

“That is not a meaning.”

“It is the current state of our knowledge.”

The collection channel displayed its own confused sequence of readings. Silicate matrix. Protein-like chains. Metallic trace elements. High water content. Unknown structures that degraded when scanned, then appeared again in the next pass.

The fragment no longer glowed.

Sana rotated the sampler in front of her lamp.

The material looked almost transparent, with a faint milky edge where the ceramic blade had separated it. No veins. No cells visible at this magnification. No motion.

It had become a sample.

The surface behind it had not become passive again.

Subtle contractions moved across the Window. They were smaller now, barely visible except where suspended particles touched it and were displaced.

Ward said, “Protocol supports a second shallow acquisition from an unaffected point.”

“No.”

The answer came before he finished.

Rodger turned toward her.

Ward did not respond immediately. “Clarify.”

“No second cut.”

“You are inside the authorized sampling envelope.”

“I know.”

“The first acquisition remained within depth and force limits.”

“I know.”

“No hazardous compound has been detected.”

“I know what the equipment says.”

Ward’s voice hardened into command tone. “Then explain the refusal.”

Sana looked at the place where her blade had entered.

Her body remained pulled away from it, though she had reestablished both boots and could have advanced in two careful movements.

“The response was coordinated across the full exposed area,” she said. “Not localized deformation.”

“Agreed.”

“The optical transmission continued past the mapped surface.”

“Also agreed.”

“We do not know the material’s total extent.”

“That is why we are sampling it.”

“We also don’t know what the surface is.”

“Correct.”

“It sealed behind the tool.”

Ward waited.

Sana heard Rodger’s breathing over the channel. Slower than hers. Close.

She continued, “A second cut would not be repetition under controlled conditions. We don’t have controlled conditions anymore.”

“Because the material reacted?”

“Because we don’t understand what the reaction did.”

“The reaction produced no measurable environmental hazard.”

“It may have opened.”

Rodger’s helmet turned toward the Window.

Ward said, “Define opened.”

“I can’t. The light moved through preexisting routes and beyond the exposed surface. We may have cut a coating, a seal, or one exposed section of something larger.” Sana kept her voice controlled while her forearm shook. “I am recommending no second penetration until we know what responded.”

She left the category blank rather than choose a reassuring noun.

Ward remained silent long enough for the regulator to cycle twice.

Then he said, “Second sample suspended pending review.”

Sana’s shoulders loosened.

The relay chimed again.

This time three channels dropped simultaneously.

Umbilical tension.

Local depth reference.

Sensor mast four.

All three returned before the system completed its fault announcement.

Rodger crossed to the relay housing and placed one glove against it.

“No movement,” he said.

Sana looked toward the frame.

“I saw the light reach that area.”

Ward opened the visual record. “The visible transmission entered rock approximately two meters short of the relay.”

“It continued past my lamp.”

“Causation between the sample and telemetry interruption is unconfirmed.”

“I didn’t say the sample caused it.”

“You implied connection.”

“I said the light reached the relay area.”

“Through solid rock?”

“Through something.”

Ward’s reply came a fraction late.

Sana knew him well enough to recognize the delay as concern rather than disbelief.

The relay’s nearest status bar flickered.

Green.

Dark.

Green again.

A soft vibration passed through Sana’s boots. Fine sediment lifted from the ledge in a narrow line, then settled before she could identify a fracture. Neither diver had moved.

The next pulse timer appeared.

Seven seconds.

Sana watched the Window instead of the waveform.

Six.

The yellow points dimmed.

Five.

Something ticked inside the rock.

Not loud.

Dry and sharp despite the water, transmitted through the ledge directly into her magnetic boots.

Four.

Another tick answered from closer to the relay.

Three.

Sana lowered her center of mass.

Two.

The blue lines beneath the membrane brightened.

One.

The pressure reached her ribs.

The ledge shivered.

The relay housing gave a short mechanical tremor. Anchor two’s load increased four percent, dropped two, then returned with a checksum error.

Rodger snapped one hand to the frame.

“Movement.”

“How much?” Ward asked.

“Minimal. Lateral.”

Sana felt another vibration through her boots.

Not the broad pressure pulse. This was sharper, transmitted directly through the ledge. A succession of dry clicks moved beneath the stone, each one close enough to feel in her ankles.

Tick.

Pause.

Tick.

Tick.

Fine sediment lifted from a seam near the Window’s lower edge.

Sana directed her lamp toward it.

A fracture no wider than a hair had appeared in the basalt.

“Ward, fresh cracking.”

“Location?”

“Lower sample wall, extending toward the relay.”

“Rodger, verify frame load.”

“Anchor two increased four percent.”

“Four-point-six,” Sana corrected.

The number climbed as she watched.

Five.

Six.

Then stopped.

No one spoke.

A pale flake of mineral detached from the wall and drifted past Sana’s visor.

The Window’s surface relaxed by a fraction.

Its yellow points vanished.

For three seconds the site looked unchanged. Black rock. Pale membrane. Relay frame. Lines rising into dark water. Two armored human figures standing where the world’s maps ended.

Ward said, “We are terminating sample operations.”

Rodger did not joke.

Sana withdrew the contact array and locked it to her forearm. Her fingers obeyed through repetition rather than sensation.

“Survey One copies.”

“Survey Two copies,” Rodger said.

“Prepare controlled return to the relay. Sana first. Rodger, maintain visual and watch the lower seam.”

Sana released her right boot.

Rock ticked beneath the left.

She froze.

The sound continued farther along the ledge, moving through stone toward the relay frame.

Her display began the next interval.

Eleven seconds.

Ward said her name.

Not as an order.

“Sana.”

“I feel it.”

She placed her right boot again rather than risk stepping across an active fracture.

The relay’s telemetry flickered.

One status bar went dark.

Then another.

Blue light appeared beneath the Window, brighter than before. It ran along the unseen interior in branching lines and vanished beneath the rock.

Yellow followed in clustered flashes.

Not toward Sana.

Toward the relay.

Rodger shifted his stance beside the frame. “Anchor two is loading.”

“Do not touch it,” Ward said. “Both of you hold position.”

Sana watched the countdown.

Six seconds.

The ticking accelerated.

Five.

A thread of silt rose from beneath the relay’s lowest support.

Four.

Rodger looked at her through two layers of curved visor. His face was only partly visible, reduced to eyes, cheekbones, and the pale reflection of his instruments.

Three.

Sana spread her feet and lowered her center of mass.

Two.

Her body tightened before the pulse.

One.

The pressure arrived.

This time the Window did not merely knock against her ribs.

The ledge answered.

A crack ran beneath the relay frame, and the whole structure gave one slow, impossible tilt.
