Chapter 28: The Rot Under the Altars

The sanctuary smelled like victory after the flies found it.

Rain came down in a greasy curtain through the broken glass canopy of the old transit atrium, ticking against helmets, tarps, rifle barrels, and the faces of the dead. The raiders had burned half the western sleeping hall before Mara pinned them in the boundary shift and let the city’s own geometry chew them apart. Now their bodies lay scattered across the concourse in pieces that did not match cleanly, torn where dead zone and Safe Zone had overlapped for three impossible seconds.

People stepped around them with the same exhausted care they gave potholes and live wires.

Mara stood beneath the cracked arrivals board, one hand pressed to the bandage wrapped tight around her ribs. Every breath dragged a hook through her side. Blood had dried beneath her collar and stiffened her shirt to cardboard. Her right ear still rang from the grenade that had taken out the east stairwell. She tasted smoke, copper, and the sour panic of too many people breathing the same air under a failing roof.

Above her, on the dead electronic board, the System’s pale numerals hovered where train times had once flickered.

SANCTUARY NODE 17-A
Status: Contested Resolved
Population: 1,842
Structural Integrity: 41%
Boundary Stability: 62% and declining
Required Tribute: Pending Calculation

Pending. Mara hated that word.

It meant the System was still counting costs.

“Mara.”

Jace limped toward her through the rain, a rifle slung across his chest and a child asleep against his shoulder. The little girl had one hand tangled in his cracked tactical vest, her knuckles white even in sleep. Jace’s left pant leg was soaked dark from knee to boot.

“You’re bleeding again,” Mara said.

“That’s my line.” He shifted the child higher with a wince. “West barricade’s holding. For now. We’ve got twenty-seven dead confirmed from inside. Forty-three injured who won’t die if they get antibiotics. Which means—”

“They might die.”

His mouth tightened. “Yeah.”

Mara looked past him to where survivors clustered beneath sagging tarps and old advertising banners. The attack had cut through more than bodies. It had taken the last illusion that any wall in the fallen city meant safety. People hunched around salvaged heaters, their faces hollow and shining in the rainlight. Every pair of eyes kept drifting upward to the System text, as if numbers might become mercy if stared at hard enough.

Near the fountain, two militia men argued over a crate of ammunition. By the escalators, a mother rocked a bundle that no longer moved. On the second-level walkway, someone had hanged three captured raiders from a length of cable without asking Mara, and nobody had cut them down.

The sanctuary’s council table had been smashed during the assault. Two of the five councilors were dead. One was missing. The oldest, Minister Vale, had lost most of his face when the militia’s first rocket hit the information booth. Leadership had become a vacuum, and vacuums in this city filled with knives.

“Where’s Kellan?” Mara asked.

Jace’s expression changed, just a fraction. Enough.

“In the infirmary,” he said. “Not as a patient.”

“What did he do?”

“Found a food line.”

“That sounds unlike him.”

“He found it because it wasn’t feeding anyone.”

Mara turned her head slowly.

Jace nodded toward the old underground corridor that had once connected the station to Saint Orison’s, the cathedral built into the foundation of three corporate towers. Before the sky split, commuters had cut through its lower cloisters to dodge rain. After the System, the cathedral had become the sanctuary’s heart. Its nave was one of the first Safe Zones to bloom. No monsters crossed its bronze threshold. No rot-mist rose from its drains. People went there to sleep without hearing claws on the walls.

People trusted it.

Mara did not like trusted places. They were where predators learned to smile.

“Show me,” she said.

Jace lowered his voice. “You should sit down first.”

“If I sit, I’ll seize up.” She started walking. Pain flared white along her ribs. She let it come and kept moving. “And if Kellan’s about to get himself shot by church volunteers, I’d rather be standing.”

They passed through the corridor under dim emergency strips powered by scavenged batteries. Water dripped steadily from the ceiling into buckets labeled by sector. The walls were tiled in old cream ceramic, every third tile stamped now with faint System glyphs that looked like tally marks scratched by fingernails. As Mara walked, her Threshold sense unfurled under her skin.

It was never a sight exactly. More like pressure behind the eyes. Boundaries appeared to her as weight and temperature: Safe Zones cool and taut, dead zones fever-hot and fraying, hidden paths like drafts under doors. Since the attack, the entire sanctuary felt bruised. Its limits trembled in ugly pulses.

But the passage to Saint Orison’s was wrong in a quieter way.

The Safe Zone boundary ahead of them should have been clean, a soft resistance like walking through a soap bubble. Instead Mara felt layers. Knots. Threads cinched too tight around something beneath the floor.

“Stop,” she said.

Jace obeyed instantly.

Mara crouched despite the scream in her side and pressed her palm to the wet tile. Under the cold ceramic, something thudded. Not machinery. Not pipes.

A beat.

Slow. Wet. Patient.

Jace watched her face. “That’s new?”

“No,” Mara said. “It’s old.”

He swallowed.

They continued.

The cathedral’s lower entrance opened beneath an arch of greened bronze. Above it, a carved saint held out both hands, palms split by stylized wounds. Someone had hung LED lanterns from his wrists. Their light trembled over a crowd pressed shoulder to shoulder before the doors.

Not waiting for shelter.

Waiting for food.

A woman in a torn raincoat clutched a ration token in both hands. An elderly man leaned on a broom handle, lips blue. Three boys no older than ten stood in a line with plastic cups, their hair plastered to their skulls. At the front, two cathedral stewards in grey robes blocked entry with shock batons taken from dead transit security.

“Please,” the woman in the raincoat said. Her voice had worn itself raw long before Mara arrived. “My son hasn’t eaten since yesterday morning.”

One steward looked past her. “The pantry is depleted.”

“You said that yesterday.”

“The faithful endure want so the whole may survive.”

“He’s six.”

The steward’s baton hummed blue. “Step away from the threshold.”

Jace’s jaw flexed. Mara kept walking.

The steward noticed her too late. Recognition widened his eyes. Everyone knew Mara Venn now. Some because she had saved them. Some because she had sealed an entire raider squad inside a shifting dead zone and listened until the screaming stopped.

“Warden,” the steward said, straightening. “The cathedral is in vigil. Father Corvin asked not to be disturbed.”

“Good,” Mara said. “I hate asking.”

He moved the baton across her path. “No weapons inside.”

Jace gave a dry laugh.

Mara looked at the baton, then at the steward. He was young, mid-twenties, pale with a rash of stress acne across his jaw. His hands trembled from hunger or fear. Maybe both.

“You’re going to put that down,” she said.

“I have my orders.”

“And I have a sanctuary full of wounded people and a priest hiding behind hungry children.”

“That’s blasphemy.”

“No. That’s triage.”

For one breath, Mara thought he might swing. The crowd went silent around them, a silence full of hope and dread. Then the cathedral doors opened from within.

Warm light spilled out, gold and thick with incense.

Deacon Sella stood framed in the doorway. She was a narrow woman with silver hair cut close to her skull and cheekbones sharp enough to cut paper. Her grey robe was clean. That alone made Mara’s temper sharpen.

“Let them pass,” Sella said.

The steward lowered his baton.

Mara stepped over the threshold.

The Safe Zone brushed her skin like cold fingers. Beneath it came that other pulse, stronger now. The cathedral breathed around her.

Saint Orison’s had once been beautiful in the obscene way rich guilt built beauty. The nave rose five stories into shadow, ribbed with black steel and white stone shipped from countries drowning long before this city did. Stained-glass saints climbed the walls, their faces fractured by earthquake cracks and System overlays. Each pane bore floating tags only awakened eyes could see.

CONSECRATED SHELTER: ST. ORISON’S NAVE
Sanctuary Rating: Moderate
Accepted Offerings: Pain, Blood, Fasting, Confession
Current Favor: Elevated
Warning: Excessive Extraction May Cause Localized Rot

Mara stopped dead.

Jace almost collided with her. “What?”

She read the words again, each one opening a cold place inside her.

Accepted Offerings.

Pain. Blood. Fasting. Confession.

The System did not use metaphor. Not when it could use mechanics.

Rows of survivors knelt in the pews with heads bowed. Not praying, Mara realized. Waiting. Stewards moved among them with bowls and linen strips. At the side altars, candles burned in clusters so dense the air shimmered with heat. The nave smelled of wax, sweat, incense, and underneath it all, meat beginning to turn.

A low chant rolled through the cathedral.

“Through hunger, we are held.”

The kneeling people answered, dull and practiced. “Through hunger, we are held.”

“Through pain, we are counted.”

“Through pain, we are counted.”

“Through sacrifice, the walls endure.”

“Through sacrifice, the walls endure.”

Mara saw a boy near the third row sway on his knees. A steward caught him before he fell and gently, almost lovingly, guided him upright. The boy’s lips were cracked. A line of dried blood marked the crook of his elbow.

Kellan stood near the chancel steps with his hands raised, surrounded by four stewards with batons. He looked less frightened than offended, which was his usual response to danger. His wiry black hair stuck up in wet spikes, and one lens of his glasses was cracked.

“Mara,” he called. “Excellent. I was just explaining how locks work to people who believe hiding things behind doors makes them sacred.”

One steward jabbed a baton into his ribs. Kellan grunted.

Jace moved forward.

Mara caught his sleeve. “Not yet.”

At the altar, Father Corvin turned.

He was tall, broad-shouldered, and unreasonably clean. His white vestment fell in heavy folds embroidered with System glyphs in gold thread. Before the end, he had been some kind of celebrity priest, the kind invited to corporate memorials and mayoral breakfasts. Now his face had hollowed into something more useful. Suffering had made him handsome to desperate people. His eyes shone with the fever of a man who had found a lever on the world and mistaken it for God.

“Warden Venn,” he said, voice carrying effortlessly to the rafters. The chant faded. “You have bled for this sanctuary tonight. For that, you have my gratitude.”

“Keep it,” Mara said. “I’m here for the food.”

A ripple moved through the kneeling crowd.

Corvin’s expression saddened, perfectly calibrated. “If only we had enough.”

Kellan made an ugly sound. “He’s lying.”

The steward raised the baton again.

“Touch him,” Mara said, “and I’ll feed you your teeth.”

The steward froze.

Corvin lifted one hand. “Release him.”

They did. Kellan straightened, rubbing his ribs. “There are locked chambers behind the south transept. Refrigerated units. Dry storage. Stacked crates. Beans, rice, protein slurry, vitamin packs, antibiotics—”

“Pantry reserves,” Corvin said. “For collapse scenarios.”

Mara looked around the nave at the hollow-cheeked people kneeling in front of him. “This is collapse.”

“This is a trial.”

“No. Trials end.”

Corvin descended the altar steps. His boots clicked on stone. “You think in bodies, Mara. I do not say that as an insult. It is your calling. Pulse, blood pressure, airway. Immediate need. But leadership requires vision beyond the next breath.”

“Funny. Everyone who says that is usually taking someone else’s breath.”

A few heads lifted. Corvin noticed. His smile did not change, but something tightened behind it.

“The System rewards sacrifice,” he said. “You know this better than most. You manipulate thresholds. You bargain with borders. You have seen the numbers respond.”

“I don’t starve children to make a wall glow.”

“No. You kill raiders. You seal men into dead zones. You decide who stands inside and who remains out. Do not pretend your hands are cleaner because your altar is concrete.”

Jace muttered, “I’m starting to like him less.”

Mara did not look away from Corvin. “Open the storerooms.”

“If we exhaust reserves, we die when the next wave comes.”

“If you keep them locked, people die before then.”

“Some deaths purchase survival.”

The words landed in the nave like a blade dropped point-first.

Mara heard the rain battering high glass. She heard someone crying softly in the back. She heard that underground pulse thud through the stone beneath her boots.

“Say that louder,” she said. “For the people in the pews.”

Corvin spread his hands. “They know. They have chosen.”

An old woman in the front row whispered, “We chose.”

Mara looked at her. The woman’s wrists were wrapped in linen. Red had seeped through in neat, deliberate lines.

“What did you choose?” Mara asked.

The old woman blinked as if waking from a deep sleep. “To give what we could.”

“When did you eat last?”

Her mouth worked. “Father says emptiness makes room for grace.”

Kellan spat on the floor. “Father says that while sitting on canned peaches.”

Corvin’s eyes flashed. “Enough.”

Mara stepped closer to the old woman and crouched. Her ribs protested. She ignored them. “What’s your name?”

“Iris.”

“Iris, did anyone tell you the System warning says excessive extraction causes rot?”

Confusion trembled across Iris’s face.

Corvin went very still.

“They can’t see it, can they?” Mara said, standing. “The warning. The terms. You can.”

“The awakened perceive more,” Corvin said.

“And you translated it into hymns.”

The nave stirred. Hunger made people slow, but betrayal had its own metabolism. It moved through them in quick glances, tightened hands, lips parting around questions they were afraid to speak.

Sella appeared at Corvin’s side. “Warden, you are wounded and angry. The battle has shaken everyone. Come to the sacristy. We can discuss this without frightening the congregation.”

“They should be frightened.” Mara lifted her voice. “All of you should be frightened. Not of the dark outside. Of what’s under your feet.”

The pulse answered. Thud. Thud.

This time, everyone felt it.

Candles shivered. A thin line of black moisture squeezed up between two altar stones and vanished.

Jace saw it. So did Kellan.

Corvin turned half a step, enough to put himself between Mara and the altar. “Old foundations settle.”

“Foundations don’t have heartbeats.”

A child began to cry.

Mara extended her Threshold sense. It spread through the cathedral in jagged lines. The nave’s Safe Zone glowed cold around the gathered bodies, but beneath the chancel, below the crypt level, something bulged against the border like rot under a bandage. Threads of offering ran down into it: hunger, blood, pain, confession. The System had accepted them, yes.

But not for the cathedral.

For whatever was beneath it.

Mara’s stomach turned.

“You didn’t strengthen the Safe Zone,” she said quietly. “You fed the dead zone under it.”

Corvin’s face hardened. “You do not understand sacred mechanisms.”

“I understand infection.”

For a moment, no one moved.

Then Kellan darted sideways.

He was not fast in any heroic sense. He was a skinny engineer with bruised ribs and bad survival instincts. But he had spent his life slipping past locked doors and people who underestimated him. He ducked under a steward’s arm, sprinted toward the south transept, and slapped a cracked access tablet against a panel hidden behind a tapestry of Saint Orison embracing flood victims.

The panel flashed red.

“Kellan!” Jace barked.

“Almost!” Kellan shouted, fingers flying. “Their security is ecclesiastical, not competent!”

Sella’s face twisted. “Stop him!”

The stewards moved.

Jace moved faster.

He hit the first steward shoulder-first, driving him into a pew with a crunch of old wood. The baton discharged into the air, spitting blue-white sparks. People screamed and scattered. Mara grabbed the second steward’s wrist as he swung at Kellan, turned with his momentum, and slammed his arm against the edge of a marble font. Bone cracked. The baton clattered into holy water gone green at the bottom.

Pain tore open along Mara’s side. She staggered, caught herself on the font, and saw Corvin raise both hands toward the altar.

Gold glyphs flared along his sleeves.

RITUAL AUTHORITY INVOKED
Node Custodian requests emergency lockdown.
Cost: Congregational Distress
Accept?

The prompt hung above the altar, visible to Mara in cruel white letters.

Corvin smiled through clenched teeth. “We all bear burdens.”

“No,” Mara said.

He accepted.

The cathedral screamed.

Not metaphorically. The sound came from the mouths of everyone kneeling, standing, fleeing. A single involuntary cry ripped out of nearly a thousand throats as invisible pressure clamped around them. People collapsed between pews, clutching their heads, their stomachs, their wrists where old cuts split open. Children shrieked until their voices broke. Iris folded forward, blood soaking through her bandages.

The Safe Zone boundary snapped inward.

Mara felt it constrict like a noose. Doors slammed. Bronze bolts shot home across every exit. The air thickened with incense and fear.

Jace dropped to one knee, teeth bared. Kellan gasped but kept typing.

“You son of a bitch,” Mara whispered.

Corvin’s face shone with sweat. “The walls must hold.”
