Chapter 4: The Weight of Seconds
Floor 2 announced itself with a change in the stone.
Kael noticed it before anyone else — or rather, he noticed it because he had been counting, because counting was what kept his mind from replaying the dead man's last heartbeat on an endless loop. Thirty-seven steps past the Floor Marker, the stone under his boots shifted from the dark basalt of Floor 1 to a paler grey, veined with threads of something that caught the torchlight and threw it back at odd angles. The walls followed suit: the hair-thin seams between blocks widened to the width of a finger, and the surface lost its seamless perfection. These stones had been cut. You could see the chisel marks if you held a torch close — faint, parallel grooves running diagonally across each face.
But beneath the chisel marks, the original surface was smooth. The same impossible smoothness as Floor 1, the same placed-not-cut quality. The newer stonework covered it like a skin.
"You're dragging," Fell said from behind him.
Kael realized he had stopped walking. He was crouching with his fingers pressed against the base of the wall, where the pale stone met the dark. The junction was clean — almost too clean, a line of dark adhesive visible only when you got close enough to smell it, something resinous and faintly chemical that the torchlight didn't reach from standing height.
"There are two layers," Kael said. "This wall — the visible surface — it's new. Coarser stone, hand-cut. But underneath it, there's something older. The original wall, the Floor 1 style. Someone sealed it over."
Fell crouched beside him, peering at the junction. "Sealed over why?"
"I don't know. But the adhesive is old. Not fresh-old, not a few years old. The edges have crystallized." Kael ran his thumbnail along the seam. Tiny fragments broke away — not wet paste but something that had hardened into a crystalline solid over what must have been decades.
"The adhesive is old," he repeated. "Whatever covered these walls was done a long time ago. And whatever it was covering—" He pressed his palm flat against the paler stone. Beneath his fingers, he could feel the faintest vibration, a hum so low it was almost subsonic, as if the wall behind the wall was resonating with something. "Something they didn't want found. Or something they wanted to change."
Maren's voice came from ahead, clipped and impatient. "Whatever it is, it's not trying to kill us right now. Kael. Move."
He moved. But he filed it away — two layers, old over older, a wall built on a wall — and added it to the small, growing catalog of things about this place that didn't match the texts he had spent his life copying.
Floor 2 was wider than Floor 1. The corridors opened into broader passages, some large enough for six people to walk abreast, and the ceiling rose to heights that swallowed the torchlight in shadow. The architecture shifted too — not just the stone, but the geometry. Where Floor 1 had been a network of branching corridors and small chambers, Floor 2 was built around a central axis: a long, straight spine corridor from which side passages branched at regular intervals, each one leading to dead-end chambers or looping back to the spine.
It should have been easier to navigate. A main corridor with known side branches was simpler than Floor 1's maze. But Pella, ranging ahead in her silent crouch, kept returning with the same signal: two fingers, a shaking motion. Multiple paths, uncertain quality. The side passages were not all safe. Some had structural damage — ceiling collapses, floor fractures, corridors that simply ended in walls of rubble. Others had creatures. And some, Pella signaled with a gesture Kael hadn't seen before — a flat hand pressed to her ear — were noisy. Sound carried from them. Scraping. Clicking. The wet, rhythmic sound of something feeding.
"We avoid the noisy ones," Maren said. "Always. Sound in the Tower means active creatures, and active creatures on Floor 2 are not juveniles."
"The crawlers on Floor 1 were juveniles," Fell said. "What's on Floor 2?"
"Shriekers," Maren said. "Larger. Faster. They hunt in swarms of eight to twelve, and they communicate through sound — the noise you're hearing is their signaling. They echo-locate. Loud sounds draw them. Quiet sounds don't fool them. The only reliable defense is not being in the same room."
Kael listened to this and felt the familiar cold weight in his stomach. Not fear, exactly — fear was too simple a word for what the Tower produced in him. It was more like a constant, low-grade awareness of mortality that colored every decision, every step, every breath. He was walking through a place designed to kill him. Every corridor was a probability distribution of death, and his job was to shift those probabilities using information that cost him pieces of himself to obtain.
He looked at the spine corridor ahead. Pella was forty paces forward, her silhouette barely visible in the dim amber light. The side passages opened on either side like mouths — dark, quiet, some of them leading to safety and some to things that ate.
"I can find a path," he said.
Maren looked at him. "Through the echo."
"There's a body ahead. I can feel it. Same as on Floor 1 — a pull, a tug. The echo is strong enough to read." He paused. "It's stronger than the one at the junction. More data. More—"
"More cost," Fell said.
"I know."
"Do you?" Fell's voice was flat, but there was something under it — not anger, not disapproval, but the careful patience of someone who had seen this before. "Because you're describing the sensation like it's an ingredient you're measuring. Stronger echo, more data, more cost. You're calculating the exchange rate. But you're not the one paying the toll."
"I am the one paying the toll."
"Are you? Because the last time you paid the toll, you spent ten minutes on the ground with blood coming out of your face, and I spent my medical supplies keeping you conscious. Those supplies don't regenerate. The time we lost getting you upright again — that's time we spent not moving, not finding safe ground, not advancing. Your cost isn't just yours. It's ours."
The words landed flat and honest. Kael looked at Fell — the stocky medic with his canvas pack and his squint-creased face — and saw nothing cruel in the assessment. Fell was not being unkind. He was being precise. In the Tower, every cost was a party cost. Every moment of incapacity was a moment when the people protecting you had to protect an extra body instead of watching for threats.
"He's right," Maren said. Her voice was unreadable. "The calculation isn't wrong, but Fell is right about the terms. You don't just spend yourself. You spend us." She held his gaze. "So make it worth it."
The body was in a dead-end chamber, thirty paces off the spine corridor.
She had been an explorer — mid-twenties, perhaps, with the lean, corded build of someone who ran floors for a living. Her gear was good: reinforced leather armor with steel rivets, a shortsword still sheathed at her hip, a lantern that had burned out hours ago, its wax pool solidified around the wick. She lay on her back with her arms thrown wide, as if she had fallen from a great height and tried to catch herself on the way down. Her face was turned to the side, mouth open, eyes shut.
No visible wounds. No blood. But the skin of her forearms was raised in a pattern of thin, parallel welts — dozens of them, running from wrist to elbow, evenly spaced, as if something with many fine legs had walked across her skin and left marks with every step.
Fell knelt beside her, examining the welts with careful fingers. "These are puncture wounds. Tiny ones — smaller than a needle point, but deep enough to reach muscle. Dozens of them, all on exposed skin. Arms, neck, face." He tilted her head. Her ears were swollen, the skin around them tight and discolored. "Eardrums ruptured. Both sides. Whatever killed her attacked in swarms, targeted exposed skin, and used sound as a weapon."
"Shriekers," Maren said.
"Small ones. Larvae, maybe, or a juvenile swarm. Adults don't leave individual punctures — they tear." Fell sat back on his heels. "She died from shock. Too many small wounds simultaneously, combined with the eardrum damage. The pain alone would have been—" He stopped. "It doesn't matter what it would have been. She's dead."
Kael looked at the welts on her arms. At the swollen ears. At the open mouth frozen in a scream that had been silenced by ruptured eardrums.
The pull was there. Stronger than the Floor 1 echo — not just a tug behind his sternum but a full-body lean, as if the air above the corpse was denser, heavier, pressing down on him with the weight of unprocessed death. He could feel the echo's shape: long, complex, layered with detail. The woman had not died quickly. The swarm had come on her gradually — first a few, then more, then a flood — and her final minutes had been a crescendo of pain and panic that had been preserved in the air above her body like heat.
"I can read her," he said.
"Kael—" Fell started.
"I can get the swarm's attack pattern. Movement, timing, approach vectors. If we're going to face shriekers on this floor, I need to know how they move. She was alive for —" He closed his eyes, feeling the echo's texture. "Minutes. She was alive for minutes while it happened. That's a lot of data."
"That's a lot of echo," Fell said. "The Floor 1 reading was thirty seconds of death. This one is minutes. The volume of sensory data scales with duration. You're talking about taking in three, four, five times the amount of information in one reading. Your last reading left you hemoraging and unable to stand for ten minutes. What happens when you multiply that by four?"
"Then I'll be unable to stand for forty minutes. And I'll know how shriekers hunt."
"Or you'll have a seizure and I won't be able to stop it."
Silence. Maren stood in the chamber doorway, her back to the wall, watching the corridor. She did not turn around. "Kael. How confident are you that the intelligence is worth the risk?"
He thought about it. Really thought, the way he had been trained to think in Ashwick — weighing evidence against cost, probability against consequence, the known against the unknown. He had one echo reading under his belt. He had survived it. But Fell was right: the Floor 1 echo had been brief, and this one was not. The difference between thirty seconds and several minutes was not just quantitative. It was qualitative. Thirty seconds of borrowed death could be endured. Minutes of borrowed death — minutes of feeling someone else's skin be opened by dozens of tiny legs, of feeling eardrums burst, of feeling the crescendo of pain build past the point of consciousness — that was something else entirely.
But the shriekers were real. They were in the side passages, hunting, echo-locating, swarming. And the party had to move through their territory to reach Floor 3. Without intelligence on the swarm's behavior — approach patterns, trigger distances, numerical thresholds — they would be walking blind through a floor designed to kill them slowly.
"I'm confident," he said.
"You're certain," Fell said. Not a question.
"I'm certain."
Fell looked at him for a long moment. Then the medic sighed, a sound that carried the weight of experience. "Then I'm going to do something I shouldn't do, because you're going to do this regardless, and I'd rather you didn't die from it." He unslung his pack and rummaged inside, producing a small glass vial filled with dark liquid. "This is a tonic. Willowbark extract, nightbloom resin, and Tower-sourced sedative. It won't stop the physical reaction, but it'll dampen the neurological cascade. Lessen the chance of seizure. Reduce the severity of the aftereffects." He held the vial out. "Drink it before you read. Not after. Before."
Kael took the vial. The liquid was warm through the glass.
"What does it cost?" he asked.
"Sleep. You'll need eight to ten hours after the reading instead of the usual few. And the aftereffects — the nosebleeds, the visual disruption — they'll be blunted, not eliminated. You'll still feel everything. You just won't break from it." Fell paused. "Probably."
Kael pulled the stopper and drank. The liquid was bitter, coating his tongue with a numbness that spread down his throat and into his chest. Within seconds, the constant low thrum of anxiety in his chest eased by a fraction — not gone, but softened, as if someone had turned down the volume on his fear without silencing it entirely.
He knelt beside the dead woman. Her welts gleamed in the torchlight. Her mouth was open, and in the depth of her throat, he could see the small, precise wounds where the swarm had entered — a dozen tiny holes in the soft tissue, each one a doorway into a death that had taken minutes to complete.
He placed his hands on her forearms, where the welts were densest, and closed his eyes.
The echo opened.
The chamber dissolved.
Kael was standing — no, she was standing — the woman was standing, in a stone chamber lit by a functioning lantern that cast white light across walls she did not recognize. Her name was somewhere in the back of his mind, a syllable he could not quite reach, and her hands were steady on the hilt of her shortsword because she had done this before, she had walked dead-end chambers before and they had been empty, just like this one, just storage alcoves or old barricade positions, nothing to fear.
She turned to leave. Her boot scraped the stone.
The first shrieker dropped from the ceiling.
It was smaller than he expected — the size of a man's fist, a thing of translucent chitin and too many legs, its body pulsing with a rhythmic contraction that produced a sound at the edge of hearing. Not a shriek. A click. A sonar pulse that bounced off the walls and returned to the creature in a fraction of a second, painting the room in echolocation.
She saw it and swung. The blade caught the creature and burst it — a spray of dark fluid and shattered chitin — and she was turning, looking up, because where there was one there were more, there were always more—
They came from the ceiling. From the walls. From the cracks in the floor that she had not checked because she had been in a hurry, because she had thought the chamber was clear, because the silence had fooled her.
Ten. Twenty. A hundred.
The first wave hit her arms. The legs were fine, hair-thin, and each one carried a barb at its tip — a piercing structure that drove through leather armor like paper and into the skin beneath. The pain was sharp, bright, immediate: not the dull ache of a wound but the electric snap of nerve endings being opened all at once. She screamed. The sound bounced off the walls and the shriekers fed on it, converging on the noise source, and more came, and more, and the welts on her arms multiplied with every passing second.
She ran. She made it three steps toward the door before they caught her legs, the swarm flowing over her boots in a tide of clicking, piercing chitin. She fell. Her lantern hit the floor and rolled, the light spinning in wild arcs that caught the swarm in flashes — hundreds of tiny bodies, all pulsing, all clicking, all converging.
The sound built. The echolocation pulses overlapped, multiplied, became a wall of noise that drove through her ears and into her skull. She felt her eardrums pop — first the left, then the right — and the world went muffled, distant, as if she were underwater. But the pain in her arms did not go distant. The pain was everywhere, a bright white blaze that consumed thought and left only sensation.
She tried to crawl. Her hands left the sword — she had dropped it, she had dropped her sword — and her palms slapped the stone, and the swarm covered her hands, and the welts climbed her fingers.
The last thing she saw was her own blood pooling beneath her face, reflecting the lantern light in a dark mirror. The last thing she heard was the click of a thousand tiny legs on stone. The last thing she felt was the understanding that she was not going to leave this chamber, that the swarm was not going to stop, that the pain was not going to lessen, and that her death was not going to be quick.
It was not quick.
The echo held. It did not release. Seconds passed — her seconds, her final seconds, except they were not seconds, they were minutes, five minutes or six or seven, an eternity of small punctures and mounting shock and the slow dimming of a consciousness that refused to go dark because going dark meant feeling nothing, and feeling nothing meant admitting that this was the end, and admitting that this was the end meant—
The echo released.
Kael opened his eyes.
He was on the floor. He did not remember lying down. The stone was cold against his cheek, and it was wet — his blood, pooling beneath his face the same way hers had pooled beneath hers, and for a terrible, disorienting moment he could not tell whose blood it was, hers or his, because the echo had not fully released and the two realities were still layered, overlapping, occupying the same space.
He could hear the clicking.
It was not the shriekers. It was the echo — still resonating, still playing in the architecture of his mind, a ghost-frequency that had imprinted on his auditory processing and refused to fade. Click-click-click-click. The sound of tiny legs on stone. The sound of a swarm closing in. It was not real. It was an echo of a sound, preserved in the death of a woman whose name he still could not reach.
"Kael." Fell's voice. Close. "Kael, can you hear me?"
"Clicking," Kael said. "I can hear clicking."
"That's normal. It'll fade." Fell's hands were on him — checking his pupils, his pulse, pressing a cloth against his nose. "Nosebleed is heavier than last time. Pupils are uneven. You're in shock — both yours and hers. Can you tell me your name?"
"Kael."
"Where are you?"
"Floor 2. Dead-end chamber. I just read—" He convulsed. A dry heave that bent him double, that brought up nothing but bile and the ghost taste of someone else's blood. "She was attacked by a swarm. Shriekers. They came from the ceiling, the walls, the floor cracks. Dozens. Hundreds. They echolocate — sound draws them. She screamed and it brought more."
"The attack pattern?"
"Cone formation. They approach from the direction of the loudest sound. If you stay silent and move away from the sound source, they'll track the noise, not you. But if you make noise — any noise, footsteps, weapons, breathing — they home in." He pressed his palms against his temples. The clicking was still there. Faint, but persistent. "The welts on her arms — the barbs on their legs inject a mild paralytic. Not enough to immobilize a healthy adult, but enough to slow reactions. The swarm relies on volume, not lethality. They don't kill with one wound. They kill with a hundred."
"A hundred small wounds," Fell said. "Shock and blood loss."
"Yes." Kael's vision was doubling. He could see the chamber — Fell kneeling over him, Maren in the doorway, Pella behind her — and he could see the woman's chamber overlaid, the same space lit by different light, the swarm covering a body that was no longer there. The two images flickered, competing, and he squeezed his eyes shut to force the dead woman's view out of his head.
It did not work. The clicking continued. Underneath the clicking, something else — a faint, rhythmic pulsing, like a heartbeat that was not his. The woman's heart. Still beating in the echo, still pushing blood through vessels that were already empty. The echo did not know it was over. The echo was a recording, and the recording had not reached the end, and—
"Kael." Fell's hand on his jaw, tilting his face up. "Open your eyes. Look at me."
He opened his eyes. Fell's face filled his vision — round, weathered, creased at the corners. Behind Fell, the chamber wall was pale grey, veined with threads of reflective mineral. Two layers. The newer stone over the older. He could see the seam.
"Can you walk?" Fell asked.
"I think so."
"Don't think. Can you?"
Kael sat up. The room tilted, stabilized, tilted again. The clicking in his ears subsided by a fraction — still there, but quieter, as if someone had closed a door between him and the sound. The phantom heartbeat faded. The overlaid image of the dead woman's chamber dissolved, leaving only the real chamber, the real stone, the real faces staring at him with expressions that ranged from concern (Fell) to calculation (Maren) to something that might have been respect (Pella).
"Swarm tactics," Kael said. His voice was hoarse. "Echo-location. Sound-directed. The side passages with the feeding noise — those are active feeding sites. Shriekers cluster around kills. If we avoid loud sounds and give the noisy passages a wide berth, we can move through the spine corridor without triggering a swarm response."
"Distance?" Maren asked.
"Thirty paces from a feeding site is safe. Twenty-five is marginal. Below twenty, they'll detect you even if you're silent — the vibration of footsteps on stone is enough at close range."
Maren nodded. She looked at Pella. "You heard him. Map the safe distances. We move quiet, we move careful, and we stay twenty-five paces from anything that sounds like a meal."
Pella vanished into the corridor without a word.
Maren turned back to Kael. "Can you keep up?"
"Yes."
"Then keep up."
She left the chamber. Kael watched her go — the straight back, the prosthetic arm swinging at her side, the absolute absence of hesitation. She had not asked if he was all right. She had extracted the intelligence she needed and moved on. That was the arrangement. That was the foundation.
Fell stayed. He was packing his supplies with methodical efficiency, but his movements were slower than they needed to be — deliberate, unhurried, the movements of a man who was choosing to stay.
"You need to sit for a few minutes," Fell said. "The tonic I gave you will blunt the worst of the aftereffects, but the neurological disruption is real. Your brain is integrating foreign sensory data. It takes time."
"Is that what you call it? Integrating?"
"I call it a lot of things. None of them are useful to you right now." Fell sat beside him, his back against the wall. The torchlight caught the grey in his hair, the deep lines around his eyes. He was older than Kael had first thought — mid-forties, not forty. The Tower aged people faster than the calendar.
"I've treated echo readers before," Fell said. His voice was different now — lower, stripped of the professional briskness he used when speaking in front of Maren. This was Fell the medic, not Fell the party asset. "Three of them, over five years of floor running. One was a guild specialist — the Ashen Collective had him reading echoes in cleared zones, extracting tactical data for their floor maps. Another was an independent, like you, solo reader with no party. The third was—" He paused. "The third was a woman in a party not unlike this one. She read echoes to keep her people alive."
"What happened to them?"
"The guild specialist is still alive, as far as I know. He reads five, six echoes a day. Has been doing it for years. He's functional." Fell's jaw tightened. "Functional is a generous word. He talks to people who aren't there. He answers questions that weren't asked. He has good days and bad days, and the bad days are very bad. The last time I treated him, he couldn't remember his own name for six hours. It came back, but the name that came back was one of the dead. Not his."
Kael said nothing. The clicking in his ears had faded to a whisper, but it was still there — a background hum, like the memory of a sound that had been played too loudly.
"The independent reader — I only treated him once. He'd read an echo from a Floor 5 death, a long one, and the trauma sent him into seizure. We stabilized him, but he refused to read again after that. Said the dead woman's voice was still in his head, narrating his life in a voice that wasn't his. He left the Tower and never came back." Fell looked at his hands. "The woman in the party — she was the best echo reader I ever saw. Better than you, maybe, in terms of raw extraction. She could pull tactical data from a reading the way you pulled the swarm pattern. But she read too many, too fast, without rest between readings. The bleed got worse. The voices got louder. She started forgetting things — her childhood, her mother's name, the way home. The dead replaced her. Not all at once. Piece by piece. She'd be talking to you and suddenly stop mid-sentence because she couldn't remember what word came next — not her word, one of theirs."
"What happened to her?"
"She climbed to Floor 18. Highest of any echo reader I've treated." Fell's voice dropped. "She died on Floor 19. Not from an echo reading. From a creature she should have seen coming — but she was distracted. Listening to a voice that wasn't there."
The chamber was very quiet. The torch on the wall flickered, throwing shadows that jumped and settled and jumped again.
"What you're doing," Fell said, "is not just reading. It's absorbing. Every echo you take in leaves residue — sensory impressions, emotional patterns, fragments of the dead person's neural architecture. The first reading is the worst, physically. But the second reading is the worst, psychologically, because the second reading proves to your brain that this is repeatable. That there are more deaths out there, and you can access all of them. Your brain starts expecting it. The pull you feel toward the bodies — that's not just sensitivity. That's your neural pathways reshaping themselves to seek out echo data. You're building infrastructure for something you can't undo."
"I know," Kael said. And he did know. He could feel it — not as an abstract concept but as a physical presence in his mind, a new room that had been built during the first echo reading and expanded during the second. A room with doors that opened onto other people's deaths. A room he could not close.
"You know, and you'll do it again," Fell said. "Because the information saves lives. Because Maren will point you at a body and ask what it saw, and you'll kneel down and open the door again. That's the trap. Not the Tower's trap — yours. The dead give you power, and the power costs you yourself, and you'll keep paying because the alternative is watching the people around you die blind."
Kael looked at Fell. The medic's face was drawn, his eyes steady. There was no pity in it. There was no judgment. There was only the flat, experienced assessment of a man who had watched three people walk the same path and seen where it led.
"The ones who hear the most voices," Fell said, "tend to climb the highest."
He let the sentence sit.
"They also tend to die the hardest."
They moved.
The spine corridor stretched ahead, flanked by side passages that Pella marked with her wire-and-knot system — safe passages marked with a single knot, dangerous ones with two, feeding sites with three. The party walked in formation: Pella leading, Maren behind her, Kael in the center, Fell at the rear. They moved in silence, their boots barely whispering against the stone, their breathing controlled and shallow. The Tower responded to their caution — the corridors remained empty, the torches burned steady, the walls held their secrets behind layers of old stone and older stone.
Kael walked and thought about layers.
The double-layered walls of Floor 2 troubled him in a way he could not fully articulate. In Ashwick, when a building was renovated, the old structure was torn down and replaced. You did not build over something you wanted to preserve — you built over something you wanted to hide. The Tower had been built over itself, floor by floor, layer by layer, with the older architecture sealed beneath the newer. The adhesive was old. The crystallization suggested decades, perhaps centuries. Someone had come through this floor long ago and decided that the original walls needed to be covered.
Why?
He thought about the dead man on Floor 1. The thought that had echoed through the death echo, preserved in the final flicker of a dying consciousness: This is not how this floor is supposed to look.
The man had been confused. Not terrified, not pained — confused. He had seen something that contradicted his expectations. A trap where there should not have been one. A mechanism in a wall that should have been solid. A floor that did not match the maps he had studied.
What if the maps were wrong? What if the floor had changed?
Kael touched the wall as he walked. Pale stone, coarse-cut, covering something smooth and dark. Two layers. Two versions of the same floor. The newer one — the one the explorers walked through — built on top of the older one. And beneath both, perhaps, a third layer, and a fourth, and a fifth, each one a different version of Floor 2, each one sealed beneath the next like pages in a book.
Or like a record.
The word arrived unbidden, surfacing from the same place that had produced the dead man's confusion. A record. Something written down. Something preserved. Something that changed when it was edited.
He pulled his hand from the wall. The phantom heartbeat from the echo reading fluttered in his chest — once, twice — and then subsided. The clicking in his ears was gone. Or rather, it had joined the other background sounds of the Tower — the distant drip of water, the low groan of stone settling, the faint hum of warm air moving through sealed corridors — and become indistinguishable from them. A new layer in the soundscape. A new voice in the chorus.
Fell's warning sat in his mind like a stone in a shoe: The dead give you power, and the power costs you yourself, and you'll keep paying because the alternative is watching the people around you die blind.
He would keep paying. He knew that, with the same certainty that had let him kneel beside two dead strangers and open the door to their final moments. He would kneel beside more. He would open the door again and again, each time paying a little more, each time losing a little of what made him Kael instead of someone else. The alternative — standing behind Fell while Maren fought blind, while Pella scouted without intelligence, while the Tower killed them one by one in corridors they did not understand — was worse.
Not worse in the abstract. Worse in the specific, the way the dead woman's death had been specific: not a concept but a sequence of small punctures, each one a decision, each decision leading to the next, the swarm building and building until the sum of tiny wounds became a death.
He would keep paying. And eventually, the cost would be more than he could afford.
But not today.
The party reached the Floor 2 descent marker two hours later. The marker was identical to the one on Floor 1 — a spiral within a circle, carved into dark stone — but set into a wider chamber with higher ceilings and a faint draft that suggested ventilation from below. The air coming up from the descent was cooler than the air in the corridor, carrying a mineral smell, like wet limestone.
Maren stood over the marker. She had not spoken in forty minutes — not since Pella's hand signal had indicated the last safe passage before the descent. Her silence was not tension. It was routine. She was saving her voice for the next floor.
"Floor 2," she said. "Twelve confirmed deaths this cycle. Six shrieker swarm kills. Three structural collapses. Two unknown." She looked at the party. Pella, motionless, her bow across her back. Fell, breathing evenly, his pack secure. Kael, pale, his shirt cuff stained with blood from the nosebleed that had finally stopped an hour ago. "Two unknowns on Floor 2. That's higher than the books say. The last cycle had zero unknowns on this floor."
"Unknown means undetermined cause of death?" Kael asked.
"Unknown means the bodies were found without an identifiable cause. No wounds, no traps, no creatures in the area. Just dead." She stepped over the marker. "Three years ago, when I ran this floor the first time, the unknown count was zero. This cycle, it's two. The floor is changing."
She descended without looking back. Pella followed. Fell paused at the marker, one hand on Kael's shoulder — a brief, grounding touch, more medic than friend.
"You hearing anything?" Fell asked. "Voices that aren't there? Sounds that don't match the environment?"
"The clicking stopped," Kael said. "An hour ago."
"That's good. That means the sedative is working and your brain is filtering the echo residue. But Kael—" Fell held his gaze. "If the clicking comes back. If you start hearing her voice when there's silence. If you smell burning oil in a clean corridor. You tell me. Immediately. No stoicism, no pretending you're fine. You tell me, and we deal with it."
"I will."
"Good." Fell released his shoulder and stepped over the marker.
Kael was the last to descend. He stood at the edge and looked down. The staircase spiraled into darkness, lit by the same amber torches that illuminated every floor, their light throwing long shadows that twisted with each turn. The air rising from below was cool and clean and carried that mineral smell, the smell of deep stone, of old places, of things buried and sealed and waiting.
He thought about the dead woman. Not her death — that was already fading, the sharp edges softening as his mind processed and filed and began the slow work of integration. He thought about her name. He had felt it during the echo reading, somewhere in the back of the dead woman's mind, a word she had repeated to herself during the climb, a name she used to anchor her courage. It was there, just beyond his reach, a syllable that did not belong to him trying to surface through layers of borrowed memory.
He let it go. Not today. The name would come or it would not, and if it came, it would be another small piece of someone else's life lodged in his mind, another voice in the growing chorus.
He stepped over the marker.
Floor 3 waited below.
