Chapter 4: Blood on the Sixth Floor

The first spider came out of the vent above apartment 6C with a sound like someone cracking knuckles in the dark.

Miles Kade looked up from the boy on the carpet.

For one thin, impossible second, the hallway outside Mrs. Alvarez’s apartment was almost normal. The emergency lights stuttered red along peeling beige walls. Someone’s smoke detector chirped every thirty seconds, useless and shrill. A trail of blood—too much blood, bright and slick—ran from the threshold to where Miles knelt with both hands pressed against nine-year-old Theo Banners’ torn abdomen.

The boy was breathing because Miles had forced him to.

Because something inside Miles had opened like a black umbrella and caught the pain meant to drown a child.

His palms still burned. Not heat. Not exactly. More like memory being poured through muscle. Theo’s pain had come into him in hooks and teeth: the instant the stairwell door burst inward, the blur of chitin, his mother screaming, the wet rip. Miles had taken it. He could still feel where the spider-thing’s leg had punched through the boy’s belly, though his own shirt was intact.

The System had called him a Trauma Shepherd.

Miles still didn’t know whether that was a blessing or a diagnosis.

The vent cover bowed outward.

“Miles,” Mrs. Alvarez whispered.

She stood barefoot in the doorway, one hand clamped over her mouth, gray hair escaping her bun in frightened wisps. Behind her, half a dozen residents crammed into the small living room. Mr. Padilla from 6F had a fireplace poker. Denise Choi, pregnant nurse from 6B, held a kitchen knife in one trembling hand and her belly with the other. Old Mr. Finch sat in an armchair with a towel pressed to his scalp, blood leaking through his fingers, his lips moving around silent prayers.

The vent cover popped free.

It hit the carpet with a metallic clang.

Something pale and many-legged poured out after it.

Not crawled. Poured.

It unfolded itself from the square mouth of the duct like a fist opening. Its body was the size of a dinner plate, round and translucent, packed with milky organs that pulsed beneath a membrane thin as wet paper. Eight legs clicked against the wall—too long, too jointed, sharp at the tips. Its head was a knot of bone-white plates, and from between them extended a cluster of black needles that flexed and tasted the air.

Miles smelled bleach, spoiled meat, and dust baked inside metal vents.

The creature twitched toward Theo’s blood.

Then the duct behind it filled with scratching.

Dozens.

Maybe hundreds.

Mrs. Alvarez screamed.

The spider dropped.

Miles moved without thinking. His right hand left Theo’s wound, and the boy’s blood surged warm between his fingers. Miles grabbed the vent cover off the carpet with his other hand and swung it like a frying pan.

The edge caught the spider midair.

It burst against the wall in a splash of gray fluid and splintered bone. Its legs kept kicking after the body ruptured, thin black claws skittering against the baseboard.

A blue-white pane of light opened in front of Miles’ eyes.

Marrow-Spider destroyed.
Contribution assessed: 42%.
Experience gained.

“What the hell is that?” Padilla barked from behind him. His voice cracked halfway through. “What the hell is that?”

More legs scratched inside the duct.

Miles pressed his palm back down on Theo’s wound. The boy whimpered, trying to curl around the injury.

“Don’t move,” Miles said, though the words came out ragged. “Theo, look at me. Eyes on me.”

The boy’s eyes rolled, unfocused. His skin had the waxy sheen Miles had seen too many times in ambulance lights.

Shock. Keep him warm. Stop the bleed. Airway, breathing, circulation. Do your job.

But there was no ambulance. No trauma bay. No radio squawking in his ear. No partner throwing him gauze. No blessed hell of fluorescent light and surgeons swearing behind masks.

There was only the sixth floor of a Chicago apartment building that had become a dungeon at 3:17 a.m., and something in the vents wanted the blood.

Miles looked toward Denise. “Towels. Blankets. Anything clean. Now.”

Denise blinked hard, then snapped into motion. “You heard him. Move! Towels, sheets, shirts—if it can soak blood, bring it.”

Her nurse voice cut through panic like a scalpel. Two residents stumbled deeper into the apartment. Someone knocked over a lamp.

Another spider squeezed from the vent.

Then another.

Padilla raised the poker. “I’ll kill them.”

“Don’t let them drop on him,” Miles said.

Padilla swallowed. He was a heavy man in an undershirt and pajama pants, with a faded tattoo of a crown on one shoulder. In the old world, Miles had seen him smoking outside the building and glaring at teenagers like he owned the sidewalk. Now his poker shook in both hands.

The first spider launched.

Padilla swung too early. The poker smashed into plaster. The spider landed on his forearm and stabbed.

He screamed.

Not the sharp yell of surprise. A full-bodied, tearing sound. The creature’s needle-mouth punched into him, and Miles watched Padilla’s skin sink inward as if the spider were drinking something deeper than blood.

Marrow.

Padilla slammed his arm against the doorframe. The spider clung. Its translucent belly clouded pink.

Denise hurled the kitchen knife.

It spun badly, handle-first, and bounced off the wall.

Miles cursed, grabbed the vent cover again, and surged to his feet. Theo gave a small broken cry when the pressure left his wound. Blood welled up immediately.

“Hold this!” Miles shouted.

Denise dropped beside Theo without hesitation, both hands planting over the boy’s abdomen. Her face went pale, but her pressure was firm. Good pressure. Trained hands.

Miles crossed the carpet in two strides and smashed the spider against Padilla’s arm.

It crunched. Padilla stumbled back, sobbing through clenched teeth. The thing peeled away in pieces, leaving three deep black punctures in his forearm. The wounds did not bleed right at first. They seeped a thick dark red that had threads of white in it.

Padilla stared at his arm. “It took something. It took—”

Another spider dropped from the vent and landed on Mrs. Alvarez’s shoulder.

She screamed and spun, slapping at it. Its legs tangled in her cardigan. Needle-mouth darted for her throat.

Miles’ heart kicked against his ribs.

He was too far.

A crack split the air.

The spider flew off Mrs. Alvarez and hit the ceiling, broken in half.

Everyone froze for half a breath.

Mr. Finch stood by the armchair, no longer praying. In his hands was an old wooden cane, raised like a rifle butt. Blood ran from his scalp into one eyebrow. His watery eyes were narrowed, calm and cold.

“I taught eighth grade for thirty-seven years,” Finch said, breathing hard. “You think I haven’t killed pests?”

The duct screamed.

It was not a spider’s sound. It was the sound of nails dragged across the inside of his skull.

The vent above the door vomited marrow-spiders.

They spilled in a pale, clattering wave: down the wall, across the carpet, over the broken vent cover and Theo’s blood. Ten. Twenty. More bodies shoving through behind them, legs tangling, mandibles ticking like rain on tin.

Panic detonated.

Residents shoved each other toward the kitchen. Someone fell. Someone shrieked, “My baby, my baby,” though Miles didn’t see a baby anywhere. Padilla swung wildly, crushing two spiders and nearly taking Denise’s head off with the backswing.

“Stop swinging over the patient!” Denise snapped.

“Get him out!” Miles shouted. “Hallway. Now!”

Mrs. Alvarez stared at him as if he’d said to jump from the balcony. “The hallway? The stairwell monsters—”

“Vents run through the apartments,” Miles said. He grabbed Theo under the shoulders. “They’re coming from inside the walls. Hallway gives us space.”

Denise grabbed Theo’s legs. “On three.”

“He’ll bleed out,” Mrs. Alvarez said.

Miles met her eyes. “He’ll die here faster.”

Something in his voice worked. The old woman nodded once, then snatched a crocheted blanket off the couch and threw it over Theo’s middle.

“One,” Denise said. “Two. Three.”

They lifted.

The boy screamed.

Miles absorbed the sound like a blow to the sternum. Theo’s pain flared against his nerves. Not enough to disable him this time, but enough that his vision snowed at the edges. The System mark buried somewhere under his skin pulsed in answer, hungry and clinical.

They moved.

Spiders chased the blood trail.

Miles backed through the apartment door, Theo’s upper body in his arms, Denise moving in sync at the feet. Mrs. Alvarez shuffled beside them, beating spiders back with a broom. Finch stood in the doorway and used his cane with vicious precision, cracking bodies when they tried to rush the threshold. Padilla followed last, panting, his injured arm clutched to his chest.

The hallway was a long red-lit throat.

Apartment doors stood open like broken teeth. People peered out and jerked back. Somewhere farther down, a woman hammered on the elevator button again and again, though the elevator doors had been sealed since the broadcast, their steel faces overgrown with faint blue symbols that crawled like frost.

The stairwell door at the end of the hall was barricaded with a couch, two bookshelves, and a vending machine Mr. Patel from 6A had somehow dragged from the laundry alcove. The barricade thudded every few seconds from the other side.

Something heavy breathed in the stairwell.

Miles tried not to look at it.

“Everyone out!” he shouted. “Out of your apartments!”

A man in a bathrobe opened 6D. “Are you insane?”

Behind him, his wife clutched a toddler with puffy sleep-swollen eyes.

From inside their apartment came a soft metallic rattle.

Miles pointed at their ceiling vent. “They’re in the ducts. Move!”

The man looked up.

The vent bulged.

He moved.

Doors opened. People spilled into the hallway carrying whatever fear told them was important: purses, knives, pillows, a framed photograph, one absurd orange cat tucked beneath a teenage girl’s hoodie. The air filled with crying, questions, prayer, and the skitter of hundreds of claws behind walls.

Miles and Denise lowered Theo onto the hallway carpet near the center, away from vents and doors. It was bad terrain. No terrain was good anymore.

“Pressure,” Denise said.

Miles dropped to his knees and pressed down again. Theo arched weakly, then sagged.

The world tightened around the wound.

The System’s ability stirred beneath Miles’ hands. He felt it like cold fingers sliding between his own. It wanted permission. It wanted a channel.

The last time, it had happened because he begged.

Now it waited.

Trauma Shepherd.

The words hung in him, sour and luminous.

He reached.

The hallway disappeared in a flash of pain.

Theo’s abdomen was not Theo’s abdomen anymore. It was a map of torn vessels and shredded muscle. Miles sensed the bleeding like open faucets. He sensed the boy’s body trying to clot and failing, blood pressure falling, organs screaming for oxygen. There were no names for what he felt. He knew medicine as training, as practice, as memory of textbooks and street calls. This was uglier and more intimate. This was standing inside the injury while it rained.

Miles pulled.

The boy’s pain came into him.

His own stomach split open.

Not really. That was the horror of it. His skin remained whole while the agony arrived complete: the tearing, the burn, the deep animal wrongness of being opened. Miles clamped his teeth down so hard his jaw clicked. A low sound escaped him anyway.

Theo exhaled. His clenched hands loosened.

Under Miles’ palms, the bleeding slowed.

Skill activated: Pain Draw.
Target: Theodore Banners.
Acute trauma siphoned: 18%.
Hemorrhage severity reduced.

“His color’s better,” Denise said. Her eyes flicked from the boy to Miles. She saw too much. Nurses always did. “Miles, your nose.”

Warmth touched his upper lip.

Blood dripped onto Theo’s blanket.

“Fine,” Miles lied.

A scream tore down the hall.

At apartment 6D, the vent exploded outward and marrow-spiders poured over the bathrobe man’s wife. The toddler tumbled from her arms, shrieking. The teenage girl with the orange cat kicked at spiders climbing her jeans. Three more residents tried to run and collided with each other.

“Finch!” Miles shouted.

The old teacher was already moving.

He walked like his hips hurt and killed like he had been waiting his whole life to be underestimated. His cane snapped down, up, sideways. Each strike landed with a dry crack. “Back to the wall! Back to the wall, you fools! Don’t give them your ankles!”

Padilla joined him with the poker, roaring to cover the tremor in his voice.

Miles looked at Denise. She was already looking at him.

“Go,” she said.

“Keep pressure.”

“I know how to keep pressure.”

He ran.

The hallway carpet squelched under his shoes. Blood, spider fluid, knocked-over coffee from someone’s mug. The smells mixed into a nauseating stew: copper, ammonia, wet bone, human fear.

The bathrobe woman had three spiders on her. One clung to her calf, another to her upper arm, the third crawling toward her mouth as she slapped weakly. Her husband stood frozen, eyes huge, holding a rolling pin like he had forgotten hands were for using.

Miles ripped the spider from her arm. Its legs sliced his fingers. The needle-mouth snapped at his wrist. He smashed it against the wall and kicked another off her leg.

“Help her!” he snarled at the husband.

The man flinched and finally moved, dragging his wife back by the armpits.

Miles grabbed the third spider before it reached her face. It stabbed him through the meat below the thumb.

Cold shot up his arm.

Not pain at first. Emptiness.

As if something had inserted a straw into his bones and begun to drink.

Miles bellowed and crushed the spider in his fist. Its body ruptured, coating his hand in slick gray pulp. His thumb wouldn’t move right. White strands clung to the puncture wound and twitched.

A System message flashed.

Status effect gained: Marrow Leech — Minor.
Bone vitality drain in progress.
Recommended action: remove feeder residue.

“That’s just great,” Miles hissed.

He scraped the white threads out with his fingernails. It felt like pulling fishhooks from inside the bone. His vision flashed black.

The toddler screamed again.

A spider had the child pinned near the baseboard.

The orange cat erupted from the teenage girl’s hoodie like a furry grenade.

It hit the spider with all four claws and a sound that belonged to a demon much larger than eight pounds. The spider recoiled, legs flailing. The cat bit down on its translucent body and shook. Gray fluid sprayed the wall.

“Mochi!” the girl screamed.

“Good cat!” Finch barked, and crushed another spider inches from the animal’s tail.

Miles scooped the toddler up and shoved him into his father’s arms. “Middle of the hall! Keep everyone away from doors!”

“What are we supposed to do?” someone cried. “Where do we go?”

The barricade at the stairwell slammed inward.

The vending machine shifted an inch.

Everyone went silent except the spiders.

From the other side of the stairwell door came a long, wet sniff.

Then claws scraped down metal.

Miles tasted adrenaline, bitter and electric.

They were trapped between the vents and the stairs. The elevator was sealed. Windows were six floors above a street now lost beyond a faint, invisible wall that had turned rain into sparks when someone threw a chair from the roof an hour ago.

Vertical dungeon.

Safe Floors.

The System had said those words like a weather report.

“Laundry alcove,” Mrs. Alvarez said suddenly.

Miles turned.

She stood with her broom in both hands, cardigan torn, one shoulder bleeding. Her face was paper-white but her eyes were sharp. “No vents in the laundry alcove. They sealed it up last year when the dryer caught fire. Remember? Inspector made them block the duct.”

Mr. Patel, a thin man with wire glasses and a bloodied cheek, nodded rapidly. “Yes. Yes, drywall over old vent. Only hallway access.”

Miles pictured it. The laundry alcove halfway down the hall, recessed behind two swinging doors, room for maybe twelve standing if they packed tight. No windows. One entrance. Defensible.

There were twenty-three people in the hall, including Theo, the toddler, Denise, and a woman clutching her bitten arm while her lips turned blue.

Not enough room.

Never enough room.

Another vent cover clanged to the floor near 6A.

Spiders poured out.

“Laundry alcove!” Miles shouted. “Injured first. Children first. Move!”

The words did not create order. They created motion, which was the best he could hope for.

Padilla and Finch formed a ragged rear guard. Mrs. Alvarez slapped spiders away from people’s feet. The teenage girl held Mochi under one arm while kicking with the ferocity of someone who had not yet learned to be afraid of dying. Mr. Patel shepherded the toddler’s family with surprising steadiness, repeating, “This way, this way, please do not push, please do not push,” as if managing a line at his corner store.

Miles ran back to Theo.

Denise had the boy stabilized as much as anyone could stabilize a gut wound on carpet during an apocalypse. Her hands were red to the wrists. Sweat stuck curls to her forehead.

“He needs surgery,” she said.

“He gets me.”

“That is not reassuring.”

“No,” Miles said, sliding his arms under Theo again. “It isn’t.”

Theo’s eyelids fluttered. “Mom?”

Miles froze for the smallest fraction of a second.

The boy’s mother had died in the stairwell. Miles had heard her last thought when he touched Theo earlier—not words exactly, but a burst of terror wrapped around one desperate image: Theo in dinosaur pajamas at age four, laughing with spaghetti sauce on his chin.

He had not told the boy.

He could not.

“We’re moving you somewhere safer,” Miles said.

“Mom said don’t take the stairs.”

“We’re not taking the stairs.”

“She’s coming?”

Miles lifted him. The pain-transfer flared through Miles’ abdomen, fresh and deep. He almost dropped the boy.

“Yeah,” Miles said, and hated himself immediately. “She’s coming.”

Theo relaxed.

The lie lodged under Miles’ ribs like glass.

They reached the laundry alcove as the hallway became a battleground.

The swinging doors had been ripped off during the barricade effort. Inside, two washers and two dryers sat dead under emergency light, their round doors reflecting red in warped circles. Shelves lined one wall, stacked with detergent, dryer sheets, abandoned baskets. The air smelled of old lint and lavender.

They laid Theo across two laundry baskets padded with towels.

“Bite wounds,” Denise said, scanning the people crowding in. “Padilla, arm. Mrs. Kim, calf. The woman from 6D—what’s your name?”

“Laura,” the bathrobe woman gasped.

“Laura’s arm and leg. Finch’s scalp. Your hand.” Denise pointed at Miles without looking at him. “And Theo.”

“Triage,” Miles said.

Denise gave him a look. “I’m aware.”

Outside, Finch shouted, “Left side! They’re bunching left!”

Padilla cursed in Spanish. A wet crunch followed.

Miles squeezed into the alcove. Too many bodies. Too much heat. Someone sobbed into their sleeve. The toddler hiccupped. Mochi growled from inside the teenage girl’s hoodie like a tiny engine.

“Listen to me,” Miles said.

Only a few people looked.

He raised his voice until it scraped. “Listen!”

The alcove quieted by degrees.

“If you’re bleeding from a bite, sit. If you can stand and swing something, you’re with Finch and Padilla at the entrance. If you freeze, you will get someone killed. If you panic, panic quietly. We are not dead yet.”

Mr. Patel nodded once. “Not dead yet.”
