The alcove announced itself through smell — old water and used coffee grounds, the scent of a place where maintenance crews had taken breaks they no longer took.

  Jake found it first.

  Griff followed him in, rifle barrel scraping the low ceiling. The others filed after — moving slower now, steps heavier than when they'd entered the Hollow.

  Marty's absence made them all feel it.

  Jake circled the perimeter, then folded onto the composite with a long exhale.

  Griff watched the dog settle, then allowed himself to lower his own pack. His shoulders protested.

  The space felt smaller without Marty. Rusted ribs lined the walls. Bent conduit hung overhead. Floor grating rang softly beneath shifting boots.

  The difference lived in the air — a missing weight that sharpened every edge.

  "Five minutes."

  Silence was the only answer.

  Don moved on instinct — passing half-rations, tightening wraps, retying the bandage slipping on Elin's wrist.

  Scarab crouched near the water unit and tugged free a sealed container wedged behind it.

  He prised it open.

  Paused.

  "…Coffee."

  Heads lifted.

  "Actual coffee."

  Mad stared at the tin as if it might evaporate. Archie let out a thin laugh.

  "We die down here and you've been hiding this?"

  "I didn't know it was here," Scarab shot back.

  Valley turned the tin in his hands, studying the faded print. "Pre-collapse."

  "How old?" Archie asked.

  "Old enough that complaining about the taste would be ungrateful."

  They brewed it weak, stretching the grounds past reason.

  The smell alone altered the room.

  For a few minutes, exits went unmapped. Threat calculations softened. They simply sat.

  Jake shifted until his spine pressed against Griff's boot.

  Contact offered.

  Griff let it remain.

  Across from him, Elin leaned back and closed her eyes, giving her nervous system a brief release from constant watch.

  Mad lifted his cup slightly.

  "To Marty."

  No speeches followed.

  They drank.

  Somewhere in the structure, airflow adjusted to account for their heat and breath. The system registered the pause — organisms stabilising.

  Griff recognised the risk.

  He finished the coffee anyway.

  Griff sat before the move, back to the wall, Mosin resting across his knees. The strap at his wrist bit when he inhaled too deeply. He breathed through it.

  Elin crouched opposite, knife angled towards the floor. Resin flecks clung to her sleeves; she scraped them away with her thumbnail. Her tagged wrist stayed tucked close to her ribs.

  Mad sat forwards, big hands flexing as if expecting a tool to appear.

  Scarab leaned against a support rib, injured shoulder wrapped tight, jaw set hard enough to jump.

  Archie lay partly on his side, ribs guarded, breaths shallow but controlled.

  Andrea stood near the alcove mouth, eyes fixed down the corridor, lips shaping silent numbers.

  Don knelt beside Jake, brushing dust from the dog's coat with methodical fingers. Jake watched faces the way he watched seams.

  Valley remained half in shadow, one hand curled around the phase rig in his pocket. It pulsed with steady tremors — a reminder the corridor kept trying to learn their rhythm.

  A faint structural creak drifted in from outside, delayed, as though the Hollow considered each sound before allowing it.

  Griff kept his gaze forwards. "We stay inside the pocket until we're ready."

  Scarab's mouth twitched. "We sound ready?"

  Stolen from Royal Road, this story should be reported if encountered on Amazon.

  Mad answered roughly. "We sound like a funeral that learned to walk."

  The line settled heavily.

  No one argued. Because it was true.

  Andrea's counting stuttered for a beat, then resumed.

  Scarab's jaw worked but nothing came out.

  Valley looked at the floor.

  They were carrying Marty in the spaces where he should have been.

  Jake stepped towards the threshold, ears forwards, then glanced back.

  Permission requested.

  Griff gave a small nod.

  Jake sat again, satisfied, shoulder pressing into Don's leg — a line of contact the system would struggle to quantify.

  Don tore open a ration strip with his teeth. The foil crack rang too loudly. He broke it into pieces and offered the first to Griff.

  Griff hesitated.

  Elin met his eyes — steady pressure: eat, stay human.

  He accepted and chewed without comment.

  Mad swallowed his like medicine. Scarab took his quietly. Archie tried to refuse, then accepted when Don's hand stayed extended.

  Andrea never turned. Don placed her portion beside her boot.

  "Forty-one… forty-two…" she whispered.

  Elin's hand caught Don's wrist as he moved to pass Valley's ration.

  "You're bleeding through the wrap."

  Don pulled back. "I'm fine."

  "You're not."

  "I'm functional." His voice came out harder than he meant. "That's what matters down here."

  The alcove went quiet.

  Don exhaled slowly, jaw working. Then he passed the ration to Valley without looking at Elin.

  She let it go.

  Valley crouched and offered his piece to Jake. The dog accepted it with careful teeth, chewing with focused ceremony.

  Mad watched. "He eats like he's solving something."

  "He is," Scarab said. "He survives."

  A thread of humour passed through them and faded.

  Don tipped the last water from his canteen cap towards Elin.

  She shook her head, eyes tracking Griff's wrist, Don's bandage, Archie's ribs.

  Don redirected the water to Archie.

  "I owe you," Archie murmured.

  "You already do," Don replied.

  Archie closed his eyes for a single breath, steadied by the swallow.

  Don adjusted the bandage at his stump, tugging it higher. The pressure shifted. For a moment the ache eased—not relief exactly, but absence. Like the thread had found alignment.

  He flexed his fingers and the sensation vanished.

  Dismissed it.

  Griff shifted; pack straps squeaked. Andrea's counting paused, then resumed.

  He spoke into the quiet.

  "Tell me what you saw."

  Andrea's jaw tightened. "The chamber priced the weight and paid it."

  Mad's hands clenched. "Stop saying it like that."

  "It is like that."

  Elin's voice cut in softly. "Say his name."

  Andrea's breath hitched.

  "Marty."

  The alcove held it.

  Griff allowed the silence to work. Speeches gave grief edges. The Hollow preferred edges.

  Elin shifted closer, her knee brushing his boot — grounding disguised as movement.

  Griff kept his voice level. "We move on a plan. Keep the line. Jake stays between Don and the corridor."

  Don looked up. "My arm's quiet."

  The statement landed worse than pain.

  "Quiet means waiting," Griff said.

  Don nodded.

  Valley stepped forwards. "The rig holds. I can cut optimisation ramps when they build. Costs power, costs timing, keeps the corridor from locking in."

  "So we keep paying," Scarab said.

  "Everything inside the Hollow has a price."

  Mad stared at the grating. "What was Marty's?"

  No answer came.

  They moved when the corridor beyond the alcove opened wide enough to breathe.

  Then it dropped.

  The passage ended at a ledge and the floor fell away into a shaft that swallowed lamplight at five metres and offered nothing back.

  Griff held up a fist.

  Everyone stopped.

  He clicked his lamp to full and aimed it down.

  Rock walls. Old service cables hanging limp. A floor somewhere below the beam's reach — maybe eight metres, maybe ten. No way to know without going.

  No way to go safely without something to hold.

  "Width?" Elin asked.

  Griff checked both sides. A narrow ledge ran the left wall — composite mesh bolted to old concrete, wide enough for one boot at a time.

  "Single file," he said. "Left wall. Don't look down."

  Scarab peered into the dark. "Love it. Straightforward."

  "Can we go around?" Archie asked, already knowing the answer.

  Valley swept the rig across both walls. "Passage is sealed the other way. This is the route."

  Mad tested the first section of ledge with his boot. It held. "So we walk a plank in the dark above a hole. Fine."

  "It's not a plank," Elin said.

  "No," Mad agreed. "A plank would be wider."

  Jake had already assessed it. He stood at the ledge's start, weight forwards, ears up. He shifted his stance, paw hovering before committing it to the mesh.

  He looked back at Griff.

  Calculating.

  "Go," Griff said quietly.

  Jake stepped onto the ledge and moved with careful, deliberate paws — testing each placement before committing. Halfway across he paused, weight shifting as if reconsidering the span, then continued.

  The pack read it.

  Safe so far. Keep going.

  "Right," Griff said. "Single file. Left hands on the wall. Right hand free. No rushing."

  He stopped.

  They all knew what happened if someone slipped.

  Jake reached the far side and turned to watch. Tail low. Eyes steady.

  Counting.

  Griff looked down at his belt pouch.

  Marty's cord.

  He'd been carrying it since the weight redistribution. It rested in his palm like a delayed decision — rough-braided salvage rope, long enough to link them all.

  "We tie in."

  Scarab looked up sharply. "We what?"

  "Before the ledge."

  "If one person goes over they'll take the next one down."

  "Not if the anchor's right." Griff looked at Jake. "And we've got one."

  Mad had seen the cord. Knew where it came from. "That's his."

  "It keeps us together."

  Silence held a moment longer than it needed to.

  "We already have walls," Scarab said.

  "Walls separate," Elin replied. "Knots bind."

  Valley's gaze lingered on the cord. The rig tremored in his pocket.

  Don shifted. "This is foolish."

  Mad's stare snapped towards him. "Say that again."

  Don looked at Jake, then back to the cord. "…Fine."

  Griff looped it around his wrist above the sling. The knot sat clean — a hold, not a restraint.

  He passed it to Elin.

  She tied it fast above her tagged wrist.

  Mad wrapped his with rough force, hiding the shake by hauling his pack tighter.

  Scarab secured it around his good wrist, jaw tightening as his shoulder shifted.

  Archie breathed through the pain while tying his, then rested his forehead briefly against the wall.

  "Ready," he said.

  Don hesitated longest.

  His stump pulsed beneath the bandage — a faint warmth that wasn't pain. The thread responding to something.

  If he tied in and lost control, the cord would pull them all towards whatever wanted him.

  "If I lose control, this makes it worse."

  "It makes it visible," Griff said.

  "It makes it ours," Elin added.

  Don's free hand clenched. The warmth in his arm faded slightly, as if disappointed.

  He swallowed and tied the knot anyway.

  His choice. Not the system's.

  Valley took the final length.

  He did not attach it to himself.

  Instead, he threaded it through the strap ring on Jake's pack and tightened it gently. His hand rested on Jake's shoulder for a second.

  Jake leaned into it — a living brace — then rose and shook. The cord tugged lightly through the line.

  Everyone felt it.

  Mad wiped his face hard. "So we're tied to the dog."

  "We always were," Scarab said.

  Jake crossed back to the start of the line and took up position at the head of the formation.

  The drop waited in silence below them.

  Eight metres. Maybe ten.

  The Hollow had not placed it to stop them.

  It had placed it to observe.

  "Move," Griff said.

  Jake led them across. One at a time, one boot at a time, the cord running between them in the dark.

  They entered as one knot — cord, breath, stubborn mammal heat — while somewhere beyond the concrete, a tolerance window narrowed.
