The water in Entry hall 041 obeyed the moon of the fifth horizon, receding three inches with every thousand beats of a resting heart.
Qiao Ming woke while the high barrel vaults were still draped in indigo darkness. He folded his sleeping mat of woven eelgrass upon his dry red stone ledge, checked the greased pig-bladder bag containing his fire-striker and willow charcoal. Then he pulled on his stiff amber-yellow oilskin coat. The hemp sailcloth was patched at the elbows with cured sharkskin, stiffened by years of salt spray, smelling of boiled linseed oil and clean ocean salt water. Beneath it, his linen tunic was bleached pale by the stone air of the halls, rough against his collarbones.
He dropped the forty-two steps of the southern spiral stair without a lantern. His bare, calloused feet knew every groove in the stone, every hollow worn smooth by hundreds of years of falling water drops. His splayed toes gripped the cold banded limestone flat stone slabs, prehensile and horn-hard, calm by the micro-algae that coated the lower risers. On the eighth step from the bottom. There, the morning backwash still lapped at the marble, he paused to let his soles acclimate to the chill.
The salt water was ice-cold, smelling of crushed sea-lilies, wet pale limestone, and the clean stone salt that had washed through the giant stone rows of stone pillars since before memory possessed a name. Around his chest ran a cross-harness of dark bridle leather, studded with green rust copper buckles that held his instruments securely against his ribs. A flat sharkskin field ledger, two soapstone slate pencils, a horn pot of rendered sheep fat, and an ox-bone reel holding sixty deep-water lengths of braided horsehair cord.
Above him, the barrel vault stretched eighty arm-lengths into the dim gloom. High in the shadows where the groin ribs intersected, thin internal clouds drifted slowly from east to west. They condensed against the carved acanthus leaves of the stone wall-brackets. They fell in a steady, rhythmic patter of heavy droplets that struck the flooded floor like distant finger-taps.
He waded into the dark water, moving toward the third terrace of the southern stone temple steps. The water reached midway up his shins, pushing against his calves with a silky, dense pushback. The salt water of the Drowned Dao was not light like rainwater. Its thickness was nearly half again that of common river flood, heavy with dissolved stone laws and stone-hard quietude.
At the center of the terrace sat Statue #0412—the Guardian of the Low Weir. The giant statue had been hewn from a single monolith of Pentelic marble, twelve arm-lengths wide at the shoulders, seated upon a massive cut stone throne. Its hands rested flat upon stone knees the size of hayricks, its unblinking eyes directed toward the dark sky-slit of the western aqueduct. During the spring moon-tide line-up three days prior, the tide had crested above the guardian’s waist. That left a thick crust of dried white salt and black ribbons of bladderwrack draped across the carved folds of its lap.
“A peaceful morning, Grandfather,” Qiao Ming murmured, his voice low and measured, pitched to stay beneath the low, deep rumble of the distant floor deck drains. “The drift-slack has reached the lower weir. Three hours remain before the under-water gates turn.”
He withdrew his boxwood scraper from his belt. He never used iron tools upon the skin of the statues. Iron was an aggressive, impatient metal. It cried orange tears of rust when exposed to the stone mist, biting into the fine pores of ancient stone and leaving permanent scars. Boxwood, cured in linseed oil and shaped with a rounded horn edge, was firm enough to dislodge stubborn acorn barnacles without scratching the polish of the pre-diluvian craft.
Working with slow, rhythmic strokes, he eased the dried weed from the guardian’s left ankle. The brittle kelp peeled away with a dry rasp, dropping into the backwash to float toward the drainage grates. Beneath the weed, the marble was pale as goat’s milk, cool and flawless. In the hollow behind the statue’s heel, two small salt water-crabs scuttled into a crevice. Qiao Ming did not disturb them. They kept the joints free of decaying silt.
When the stone base was cleared, he unhooked his eight-sided lead sounding bob from his hip. The eight-pound weight of pure soft lead had been cast with a hollow animal fat cup at its narrowed base. He took a dab of sheep fat from his horn pot. He packed the recess until the grease was level with the lead rim—arming the lead to capture whatever rested upon the underwater foundations.
He stepped to the edge of the terrace and cast the weight into the sunken drain channel. The braided horsehair line hissed off the bone reel, the black stallion hair impervious to swelling or rot. He let the lead run until the cord went slack at twenty-two arm-lengths. Tugging twice to set the animal fat into the silt, he hauled the line back hand-over-hand, coiling the wet cord across his left forearm.
He examined the base of the lead weight under the gray light drifting from the high window row. Embedded in the white animal fat were tiny flecks of pale green jade dust, crushed cockle shells, and fine pale limestone silt. The substrate was clean. No dark sludge had piled up in the channel, meaning the deep drain tube valves two leagues below were still drawing freely.
He cleaned the lead with a dry scrap of hemp, wiped his fingers, and took up his brass star-compass. The instrument was heavy, cold against his salt-rough palm. Its nested rete plates, cast from salt-resistant deep-sea bronze, were etched with the map points of drowned star-patterns. He lifted the sighting rule toward the high arch of the Broken Stone railing, where forty arm-lengths of carved marble low roof wall had snapped into the deep pit during some unrecorded disaster eons ago.
The reading was steady. The sound hum of the entry hall held at a deep hum, the calm smooth-flowing deep ring produced when water drained through the seventy-two hidden floor grates at an even speed. He noted the depth and the shear on his sharkskin slate with a willow-charcoal pencil, blowing away the gray dust before sliding the tablet back into its oiled pouch.
He was re-securing his reel when the floor shivered.
It wasn’t the rolling, underground thrum of an approaching tidal bore. A tidal bore rose from the foundations, heavy and rhythmic, shaking through the bedrock like the heartbeat of an iron whale. This shaking was sharp, high-pitched, and brittle. It traveled through the stone flags like the shudder of thin ice struck by an iron awl.
The surface of the receding tide, mirror-still only moments before, developed a tight cross-hatch of standing ripples. Fine white silt, settling quietly into the joints of the floor flags, leaped into mid-air in pale clouds.
Then came the sound.
It tore through the vaulted silence of the hall—a dry, screeching rip that set Qiao Ming’s teeth on edge. It sounded like a bolt of raw, unbaked silk being wrenched wildly apart across the sharp tooth of a rusted scythe. The petrels nesting in the stone beard of the giant statue eighty arm-lengths overhead took wing with wild cries, circling into the ceiling mist.
Qiao Ming did not drop his tools. He stepped back onto the dry fourth tier of the stone temple steps, his toes locking over the stone lip to anchor his weight. His left hand slid down to the eight-pound lead bob at his hip, his thumb resting against its animal fat-packed cavity.
High above the flooded floor, three paces out from the fractured edge of the Broken Stone railing, the air tore open.
It didn’t open like a door or a stone hatch. Space itself seemed to buckle, creasing along an invisible fault line before snapping apart. An upright scar, twelve arm-lengths in height, split the empty gloom. Around its jagged outer edge, the air glowed with a sickly, unstable violet hue, like copper shavings tossed into a fire.
The smell arrived on the sudden downdraft. It was violent, choking, and entirely foreign to the Hall. The clean scent of ancient stone, cold salt water, and wet kelp was drowned in an instant by the stench of scorched red stone, acrid sulfur, crushed stone ink. The sharp, burning ozone of burst magic charms.
“The skin of the sky,” Qiao Ming whispered, his slate-gray eyes widening as he tracked the disturbance.
From the violet seam, showers of purple sparks tumbled downward. They fell through the shadow like blazing bright embers, striking the dark water of the entry hall with sharp, poisonous hisses. Wherever a spark touched the salt water, a ring of oily, rainbow-bright scum spread across the surface, turning the green water milky and curdled. The salt water hissed and boiled, giving off thin plumes of white steam that smelled of scorched pitch.
Through the widening tear, Qiao Ming glimpsed something that made the skin along his forearms prickle with cold dread.
Beyond the crack, there was no vaulted stone. There were no columns, no gentle ceiling clouds, no calm tiers of sleeping statues. There was only a huge, howling blackness—a dry, freezing void where distant points of light were guttering and dying, leaving trails of dead gray ash. A freezing draft blew through the rift, carrying a chill that had nothing to do with the cold of sea water. It was the total chill of an empty room where the hearth had burned out eons ago.
The giant statue behind Qiao Ming remained motionless, yet within its hollow chest cavity, the trapped air began to hum. It was a mournful, low-hum sour note, shifting upward from a deep hum toward a clashing pitch that grated against the stone ribs of the hall.
Qiao Ming reached into his tunic, touched the oiled leather wrapping of his journal, and kept his breath slow and even. The House had stood through ten thousand floods. It had swallowed dynasties, stars, and forgotten gods into its quiet, salt-washed depths. But as he watched the purple sparks scorch the clean water of Entry hall 041, he knew that what had arrived through the tear was not born of stone or sea.
It was an intrusion from the dying world outside, and it carried the smell of hunger.
