The stone beneath Oakhaven didn’t merely shake. It melted.
When the five-story Aeterna Monstrance struck the marble nave eighty paces above, the bone-shaking moving load didn’t scatter into the earth. It drove straight down through the vaulted limestone crypts, shattering the ancient stonework arches like brittle pottery and puncturing the vaulted ceilings of the lower water tanks forty paces below the street.
Then the water came.
The great town canal of Oakhaven—a raised stonework aqueduct that had supplied the cathedral’s baptismal fonts, cooling pipes, and clerical fountains for two hundred years—collapsed inward. Millions of gallons of murky, freezing river water poured into the breach, roaring through the burst crypts like an underground tidal wave.
In the dark, vaulted drainage tunnel beneath the western cross-hall, the surge arrived as an ear-splitting, high-pressure roar that set the iron floor-grates shaking against their stone beds.
“Move! To the higher narrow high walkways!” Sergeant Justin roared, his steel visor thrown open, his broadsword sheathed as he shoved two elderly weavers onto the narrow brick ledge that ran along the tunnel wall. “Keep the children between the knights! Don’t let the current drag you into the intake grates!”
The water hit them knee-deep. A violent, churning torrent of black mud, cemetery lime, and floating fragments of church timber that slammed against Ren Vale’s leather boots with terrifying driving force.
Ren stumbled against the wet dark rock wall, his left shoulder screaming where Brother Ren’s dead weight rested against him.
The Disgraced Saint was strapped to a crude stretcher made of two ash poles and a torn choir mix, carried by four burly mutineer knights. Brother Ren’s head rolled limply with each jolting step. His scorched skin was pale beneath the soot, his breathing a faint, wet rattle that barely rose above the thunder of the floodwaters. On his left arm, the cooled lead melted rock waste of his melted purification basin gleamed like dull pewter in the torchlight, an unchanging, misshapen shield welded to his flesh.
Beside Ren, Mira Vale held a flickering pitch torch in her left hand. She held the flame high above the spray.
Her right arm—crystal-clear from collarbone to fingertip—gleamed with a deep, smoky soft glow in the torchlight. The see-through quartz crystal caught the surrounding sound shakes of the collapsing cathedral above. It shook with a high, sustained ringing that sounded like a silver chime struck in a quiet room.
Mira suddenly stopped, planting her boots on a slippery stone block. She pressed her quartz palm against the curved brick vault of the ceiling.
“Ren! Stop the line!” Mira shouted, her voice cutting through the roar of rushing water.
“We can’t stop, Mira!” Vane Vale yelled from five paces ahead, his trousers rolled to the knee, his fine leather shoes drenched in black slime, his ivory-headed cane raised like a marshal’s baton. “The water-system inflow is increasing at an exponential rate! Every second we loiter in this drainage under-road drain adds forty cubic feet of water to our immediate liabilities! I’m already carrying six ledgers in my waistcoat that are absorbing moisture!”
“The keystone is shearing, Vane!” Mira yelled back, her eyes wide as the quartz in her arm hummed at a wild, piercing pitch. “Listen to the hum! The vault above us isn’t carrying weight anymore—it’s slipping!”
The contract ledger ratified: Sunken Sluice Drainage. Underground Sector: Lower Cisterns of Oakhaven (Depth: 40 Paces). Water-system Vector: Ruptured Canal Aqueduct / Inflow Surge. Current Flow Rate: 12,000 Gallons / Minute (Churning). Ceiling Strength: Stage 4 Sound Stress / Basalt Slabs Shifting. Evacuation Vector: Outfall Sluice Gate #3 -> Blackwater Basin.
Ren stepped forward, splashing through the freezing black surge. He pressed his unburned left palm against the mortar beside Mira’s crystal hand.
His careful scribe’s touch—sharpened by years of detecting tiny erasures in thick parchment—felt the stone moving. It wasn’t a violent shake. It was a slow, sickening glide. The three-foot blocks of porous limestone, soaked with water and cracked by the Monstrance’s fall, were sliding past one another as the lime mortar washed away in the torrent.
“Justin!” Ren shouted. “Form an iron wedge! Right now!”
Sergeant Justin didn’t hesitate. The veteran Justiciar barked a command, and six heavily armored knights slammed their heavy heater shields together in a linked arch, bracing their iron shoulders against the low brick vault directly above the stretcher.
CRACK-BOOM!
A five-ton slab of dressed limestone snapped from the ceiling, crashing down directly onto the locked shields.
The impact sounded like a siege cannon firing inside a cellar. Two of the knights dropped to their knees in the muddy surge, their armor groaning under the titanic weight. But the shield-wall held. White dust and crushed lime sprayed across the water in a blinding cloud as the falling debris was deflected into the deep drainage canal beside the ledge.
“Pass under! Quickly!” Justin grunted, his teeth bared in agony as the iron strap of his shield bit deep into his shoulder muscle. “Move the monk! Move the women!”
Ren grabbed the ash poles of Brother Ren’s litter. He hauled with all his strength alongside the leftover two knights. They dragged the stretcher through the narrow gap beneath the buckled shield-wall. Their boots skidded on slick shale, until they cleared the danger zone.
Behind them, Justin and his men rolled sideways into the water as the rest of the ceiling collapsed with a thunderous roar, fully sealing the tunnel behind them in an iron-hard wall of rubble and rising water.
The retreat was cut off.
The water was thick with hundreds of years of cathedral refuse. Melted beeswax tapers, floating prayer pamphlets inked with fading purple script. The foul, rotten-egg sludge that had washed down from the higher alchemy labs of the Choir of Dawn. With every step, the suction of the underwater cobblestones pulled at Ren’s boots, threatening to drag him down into the blind drainage drain pits that pitted the floor.
Father Garrow waded alongside the third rank of mutineer knights. His wooden staff tapped the hidden stones ahead of the children. The old leper’s face was etched with grim resolve. His burlap shawl pulled was tight around his neck to protect his scarred throat from the icy spray.
“Keep your footing on the center crown, children!” Father Garrow shouted, his raspy voice echoing through the low brick archway. “The gutters along the walls are deep enough to swallow an ox! Follow the steel shin guards of the knights!”
Vane Vale was muttering a nonstop, wild stream of arithmetic under his breath, his eyes darting to every dripping fissure in the stonework.
“A total town building failure!” Vane hissed, lifting his frock coat tails higher as a wave of muddy foam broke against his hip. “An total public works default! They taxed the salt weavers forty thousand sovereigns over sixty years for sewer upkeep. They haven’t repointed the lime mortar since the Second Regency! This entire drainage basin was designed by clerical amateurs who understood neither high-pressure friction nor fluid dynamics! If we drown in forty cubic arm-lengths of consecrated bilge, I’ll sue the Synod’s estate in the Seventh Circle of Hell!”
“Save your breath for wading, Vane,” Ren grunted. His shoulder burned as he adjusted his grip on the stretcher pole. “The current is picking up.”
The only way forward was downstream, toward the deep drainage water gates that emptied into the Blackwater River.
They pushed forward through the winding aqueducts, the water rising from their knees to their waists. In the flickering torchlight, the faces of the forty lepers and weavers were pale masks of tiredness and terror. Children cried silently, carried on the shoulders of mutineer soldiers. Old men clutched damp bundles containing the few copper coins and linen rags they had saved from the Leper Wells.
After twenty minutes of wading against the swirling current, the tunnel opened into a massive underground junction: the Great Siphon Cistern.
Here, four massive brick aqueducts came together into a huge circular cave sixty paces across, supported by twelve huge granite columns. In the center of the chamber, three flat-bottomed freight barges—used by the church for transporting coal and barrels of sacramental wine—lay moored to heavy iron rings along the stone quayside.
The barges were old, their oak timbers black with pitch. But they were high and dry above the canal locks.
“Vessels secured!” Vane Vale shouted, splashing through the shallows toward the stone mooring pier. “Three forty-foot river barges! Flat-bottomed draft, oak planking, caulked with pine tar! Not elegant, but the floating lift shifted weight is enough to float fifty passengers and three tons of salvaged freight!”
Vane turned to Ren. He wiped canal mud from his lapel with a silk handkerchief that was now stained permanently black.
“However, we have an immediate supply emergency,” Vane said. He lowered his voice as he glanced at the litter being carried up the stone steps. “Brother Ren’s body heat has breached forty degrees. His skin is streaming heat like a baked-clay kiln. If we don’t stabilize his body saturation within the hour, the Disgraced Saint won’t survive to see the river.”
Ren climbed the stone stairs to the dry quay, his boots squelching with each step.
Beside the barges, in the shelter of a dry brick nook, the knights lowered the stretcher. Brother Ren lay trembling beneath the damp wool blankets, his lips dry and cracked, his skin streaming a dry, feverish heat that made the cold air above his chest shimmer like a summer road.
Ren knelt beside his alternate self, reaching out a trembling hand to touch the monk’s blistered forehead.
The skin was burning.
