The hatch behind him clanged.
Metal on metal, fast and decisive. Not the slow patience of earlier postures. Red did not linger. It shut.
The Underworks artery Mark had dropped into stayed low and cold, water running along a narrow channel and slicking the stone where it should have been dry. The ceiling scraped close enough that the buckler's weight threatened his torn shoulder every time he tried to lift his left arm higher than his chest. He kept the buckler tucked tight now, not extended. The forearm beneath it still carried numbness from blunt impacts, and numbness made every adjustment late.
Late got men held.
Held got men killed by quiet.
He ran anyway.
Inhale—two steps.
Exhale—two.
The count was a leash on speed and a leash on the lie of distance. The curve had already proven it could steepen past the point of safety. Quiet did not need to be complete. It only needed to feel possible.
Behind him, sealing metal and muffled commands stayed present through the cracked hatch seam he'd left. He had left it cracked on purpose. Not for escape. For sound. Sound helped the mind refuse the idea of calm.
He hit a bend and the artery rose, not in elevation, in temperature. Warmer air pushed through the corridor, smelling of sweat and oiled leather. Human smell. Human presence.
Intent.
His lungs eased a fraction under the promise of proximity, and he used the fraction to adjust his load without stopping. The mid-tier ringkey at his belt sat warm against cloth when the corridor walls showed etched squares. Recognition again. Attention again. The short sword stayed low in his right hand. The bootknife pressed against his side under cloth, still not properly strapped, and the edge of its sheath dug into skin when the corridor tightened. Tools—awl, hook tool, small hammer—were bound under wraps. The sling looped his wrist. The stone pouch rode heavy at his hip.
He could feel the weight of everything now.
Weight was leverage.
Weight was also burden.
The artery opened into a narrow junction where an iron-banded door sat half closed, not a seal plate door, not gate teeth, but a service slab with an etched square above the latch and a slit beneath.
A tier door.
The square glimmered faintly in torchlight as if it was already active.
Mark slowed without stopping.
Weight shifting. Knees bent. Boots flat.
The door's latch clicked once—then again, faster.
Red cycles.
He could hear bolts inside moving in quick, impatient sequence, as if the door were preparing to deny by default and allow only in a short window.
A window was a trap and an opportunity.
He shoved the ringkey into the slit.
The etched square warmed, not biting, but checking. A fraction of hesitation that hadn't existed before the protocol flip.
Mark felt the time cost in his chest as tension.
The drain didn't bite. Not yet. But it watched.
The bolts withdrew.
The door opened.
Warm air spilled out, thick with sweat, stale breath, and cloth that had been worn too long without washing. The smell of bodies at rest.
Barracks.
Mark stepped through and did not close the door fully.
Fully shut meant quiet.
Quiet was poison.
He left it cracked just enough that corridor noise could leak, then moved inside.
The room was tight.
Not a hall, not a wide dormitory. A narrow barracks cell built into the fortress like a pocket. Bunks lined both walls in two tiers, wood frames bolted into stone. Footlockers sat beneath the lower bunks, lids half open. A rack held belts and straps and spare boots. A shelf held folded cloth, bundles tied with twine, and a stack of small tins sealed with wax.
A lantern bracket burned low, flame steady, light held close.
This place was meant for men to sleep, dress, eat, then leave.
It was not meant for a hunted asset to loot.
That was why it mattered.
Mark's stomach tightened at the thought of what he had not had since he arrived: water. Salt. Bandage cloth that wasn't torn from a dead man. Food that didn't require him to kill to feel full.
The curse made "full" meaningless in one direction and lethal in another. Refill could flood his meters, but it didn't feed the body long-term. It didn't replace water lost to breath. It didn't heal tears. It didn't patch skin. It didn't keep him alive if the drain forced him to run for hours without a chance to drink.
He needed supplies.
Not comfort.
Function.
Loot fast.
The barracks room was not empty.
Four men were inside.
Half-armored.
Not fully dressed. Not in formation. Two sat on the lower bunks with boots unlaced, hands on straps. One stood at the shelf with a tin in hand, mouth open mid-sentence. The fourth lay on the upper bunk, head turned toward the wall, breathing slow.
They weren't expecting anything.
Their eyes turned to Mark at the same time.
Wide.
Confused for a half beat.
Then training tried to snap into place.
One man's hand went for a belt knife.
Another reached for a short spear propped in the corner.
The standing man stepped back and knocked a tin off the shelf, metal clinking loud.
Clinks were signal.
Signal meant more boots.
More boots meant pressure.
Pressure meant breath.
Mark couldn't afford to linger in this room long enough for a full response to arrive and turn it into a box.
He also couldn't afford to leave without the supplies.
Read.
He read their postures in a single glance.
Half-armored meant slower. Slower meant they weren't immediate pins, but they could become holds if he let them reach.
Hold was the enemy.
The buckler tucked against his body meant his left side was protected close, but his ability to extend and deflect was compromised by the shoulder tear. His sword arm was clean, but wide swings would torque ribs and invite grab.
He needed short work.
No theatrics.
No full engagement.
He needed to turn these men into obstacles long enough to grab what mattered and exit.
Test.
He moved to the shelf first.
Not to fight.
To loot.
That decision was cold and procedural. It ignored the men as if they were furniture.
The standing man lunged, belt knife half drawn.
Mark didn't cut the knife hand.
Cutting the hand was a fight.
He shoved.
Buckler rim into sternum, a short brutal push that used his whole body weight without twisting his torso. The standing man staggered backward into the shelf, knocking cloth bundles loose.
Cloth fell.
Bandage cloth.
Good.
One sitting man stood, boot unlaced, and tried to thrust a short spear forward like a staff, aiming to pin Mark against the opposite bunks.
Mark stepped inside the thrust.
Buckler tucked, he used the buckler face to redirect the shaft into the bunk frame. Wood groaned. The spear tip missed.
Mark's left shoulder screamed with the impact because even tucked, the buckler still transmitted force through the unstable joint. Breath hitched for a fraction.
The drain stirred at the breath loss.
Mark ended the opening before it could become collapse.
He drove the sword point into the spearman's throat gap under the jawline.
Short thrust. Tight movement. No arc.
Blood spilled.
Heat slammed through Mark.
Refill.
Breath returned full. Tremor vanished. The rib stayed cracked. The shoulder stayed torn. But his body's immediate function snapped back into alignment.
The spearman sagged.
Mark shoved him aside to clear space.
The second sitting man—still on the bunk—tried to stand and grabbed Mark's cloak hem, fingers tightening.
A grab was a hold attempt.
Hold was death.
Mark did not cut the fingers.
Cutting fingers took time.
He stomped the wrist.
Not full force—enough to break grip.
Bone cracked.
The man screamed.
Noise.
Pressure.
Good.
Not safe.
Useful.
The man on the upper bunk rolled toward the edge, waking fast, trying to drop down on Mark's back.
Mark felt movement above, not by sight, by air shift.
He stepped away from the bunk edge and let the upper-bunk man drop wrong, landing on the lower bunk frame with a hard thud that shook the room.
Wood cracked.
A groan.
The upper-bunk man's ankle twisted.
He cursed, trying to stand.
Mark didn't kill him.
Not yet.
Kills were dose.
Dose was escalating.
He needed one kill to reset function and buy seconds, not a massacre that would raise Red response faster.
He already had his refill from the spearman.
Now he needed speed.
Break.
He broke the room's stillness into chaos and used chaos to loot.
He grabbed two cloth bundles off the shelf—rolled tight, clean enough. Bandages.
He shoved them under his belt wrap and across the buckler strap to secure them.
He grabbed a small tin with a wax seal and snapped it open with his thumb.
Coarse salt.
The smell was faint, but the crystals inside were unmistakable. Salt meant more than taste. Salt meant the ability to keep a body from cramping and failing under sustained run. It meant a way to treat water and wounds. It meant leverage against the body's own betrayal.
He stuffed the tin into his pocket.
The standing man—still upright, knife now fully drawn—lunged again, eyes bloodshot, moving with panic rather than discipline.
Mark didn't duel him.
He used the bunk as a barrier.
He shoved the man's shoulder into the bunk frame with the buckler, pinning him for half a beat, then stepped past.
The man tried to hook Mark's belt wrap, fingers catching cloth near the bootknife sheath.
The bootknife pressed hard into Mark's rib line as the cloth tugged.
Pain flared.
Not the rib crack—surface pain.
Distraction.
Mark couldn't afford distraction.
He yanked the cloth free and felt the bootknife shift.
The sheath slipped.
The bootknife dropped.
Metal kissed stone with a soft clink.
A small sound.
In this room, it felt loud.
Mark did not stop to pick it up.
Stopping meant hold.
Hold meant drain.
He let the bootknife go.
Cost.
The loss was immediate and real: secondary blade gone.
Real steel remained, but redundancy mattered in close quarters.
He paid the cost because he had to keep moving.
He reached for the canteen.
It hung from a hook on the wall rack, leather strap looped, metal cap dull.
He grabbed it and yanked.
The strap held.
He didn't have time to unloop it cleanly.
He cut it.
One short slice with the sword edge, tight and controlled.
The canteen came free.
He jammed it into his belt wrap and felt its weight swing.
Swing meant clink.
Clink meant signal.
He wrapped cloth around it quickly as he moved, using one of the bandage rolls as a muffler.
Water inside sloshed.
The sound was a promise.
He didn't drink now.
Drinking required a pause.
Pauses invited quiet in the mind even in a loud room.
He grabbed food next.
Jerky was stored in a sack under the shelf, tied with twine.
He tore the twine with the hook tool and shoved a handful of strips into his pocket.
He didn't count them.
Counting was time.
Time was the enemy.
The men were recovering.
The wrist-stomped man crawled off the bunk, screaming and clutching his arm.
The standing knife man was trying to get around the bunk frame again, eyes fixed on Mark's throat.
The upper-bunk man had managed to stand, limping, reaching for a spear.
And the spearman Mark had killed was still bleeding on the floor, body sagging, blood pooling in the gutter groove cut along the wall.
Blood smell thickened.
Mark's lungs stayed open under threat and noise, but the drain's new curve waited under the sternum like a second clamp, ready to bite the moment he stepped out into a quiet seam.
He needed to exit this room with pursuit attached.
Not caught.
Attached.
Attached meant pressure.
Pressure meant breath.
Adapt.
He turned the room's door into the lever.
The cracked door behind him was still open a handspan, letting corridor sound leak.
Mark moved toward it without showing his back fully, sword low, buckler tucked, shoulders square.
The knife man lunged one last time, desperate now, trying to hook the belt wrap and pull Mark off balance.
Mark used the buckler as a battering wedge and shoved the knife man into the doorframe.
The impact pinned the man's shoulder against wood.
The man's knife arm was trapped awkwardly.
Mark didn't cut the knife arm.
He ended him.
Short thrust under jawline.
Blood spilled.
Heat slammed through Mark.
Refill.
Breath returned full. The shoulder didn't heal. The rib didn't heal. But the immediate function reset again, and he needed the reset for what came next.
The man slumped in the doorway.
His body blocked it.
A body in a doorway was a wedge.
It bought seconds before anyone outside could see in cleanly or shove through.
Mark slipped past the slumping body into the corridor and did not close the door.
He left it jammed by the corpse.
Noise and shouts from inside the barracks room continued—panic, scrambling, the limping man's breath. Those sounds would draw response.
Good.
He ran.
Not sprint.
Controlled pace.
Inhale—two.
Exhale—two.
The canteen thumped against his belt under cloth wrap. The salt tin pressed against his thigh. Bandage rolls sat tight under straps. Jerky strips were in his pocket.
Board-state changed.
Supplies acquired.
But supplies were finite.
He had taken what he could in seconds. The fortress held more, but he couldn't stay for more without being held.
He ran down the corridor that smelled like oil and stone dust, and the moment the barracks door noise dulled behind turns, his chest tightened again.
The drain tested the idea of space.
He forced the idea away.
He threw a stone behind him.
Clatter.
Roll.
Tick.
Then he heard what he needed most.
Boots.
Not one set.
Two.
Converging cadence.
Red synergy.
A voice called from somewhere behind.
Not shouted.
Clipped.
"Barracks!"
Another voice answered immediately, closer than it should have been.
"Seal lanes."
The words were switches. The fortress moving like a machine.
Mark's lungs stayed open under the proximity of intent, but the new supplies changed his options in a quieter way that mattered more than comfort.
Bandages meant he could bind the torn shoulder, not heal it, but restrain its movement so the buckler didn't tear it further.
Salt meant he could prevent cramps and keep breath and muscle honest longer.
Water meant he could fight the body's slow betrayal under a curse that punished quiet and demanded motion.
Jerky meant he could function without relying on kills for every small reset.
He couldn't stop to use them yet.
Not here.
Not under Red.
He ran deeper into Sealskin with the knowledge that the fortress's best kill method was stillness, and the only answer he had was motion.
His breath count steadied again.
Inhale—two.
Exhale—two.
Behind him, the barracks door would be cleared. The corpse wedge would be removed. The half-armored men would shout what they had seen.
And the fortress would learn a simple new fact about him:
He was no longer just stealing keys.
He was stealing time.
