The disused washroom at the rear of the Ferry Landing Kitchen smelled of thirty years of stale laundry soda, rotting cedar tubs. The sour silt stench of the river backing up through uncapped drains. It was nine feet wide by twelve feet deep, carved straight into the lower limestone river terrace, with a vaulted ceiling of wet stonework that cried steady, rust-colored tears into the gloom.
Pella Rook set her bucket of vinegar wash on the floor, the wooden staves clattering against the uneven flat stone slabs. Beside her, Eren unhitched his canvas tool roll. That let it unspool across an upturned laundry trough. Inside were his trade tools. Two flat-bladed cabinet scrapers, a forged iron drawknife, a heavy cold chisel, a wooden mallet made of lignum vitae, and three wire brushes with handles worn smooth by his father’s hands.
“Look at this buildup,” Eren said, kicking the base of the nearest wall with the steel toe of his work boot. A sheet of white, brittle turning to stone snapped away from the stone, shattering into chalky flakes. “That’s pipe lime three inches thick. The laundry tubs overflowed back during the winter thaw. Then, the lime in the river water leached out of the mortar and baked onto the flags like kiln melted rock waste. If we set the arch on this, it’ll tilt half an inch the moment someone steps on the threshold.”
“Then we clear it to the bare stone,” Pella said. She knelt on the cold floor, pulling her wool apprentice sleeves up past her elbows. The stone bit through the knees of her trousers, soaking them with icy moisture.
She took the cold chisel in her left hand and the heavy wooden mallet in her right. Placing the edge against the hardened ridge where the floor met the east wall, she struck the head of the chisel with a rhythmic, measured blow. Clack. Clack. Crack. A wedge of hardened pipe lime gave way. It exposed the dark, smooth gray face of dressed river granite beneath.
For two hours, they worked in unbroken rhythm. The sound of metal chipping stone filled the narrow vault, competing with the muffled roar of morning trade from the main kitchen on the other side of the heavy oak door. Sister Merrow was feeding the wagon drivers. Every twenty seconds, the dull thrum of a heavy kettle hitting an iron stove-hob or the scrape of wooden benches echoed through the stonework.
While Pella chipped the outer edge, Eren tackled the blocked floor drain at the center of the room. The iron grate was rusted solid into its rebate, coated in a greasy mixture of animal fat and coal dust. Eren wedged his iron pry-bar beneath the lip, bracing his boot against a floor seam. Then it threw his weight backward.
With a screech of snapped iron oxide, the grate popped free, releasing a foul burp of sewer gas that tasted of rotten greens and stale river muck.
“Hand me the ash clearing-rod,” Eren grunted, coughing into his shoulder.
Pella passed him the six-foot timber rod. Eren drove it down the four-inch lead pipe, twisting and ramming the shaft against the blocked path. Ten feet down, at the bend where the waste line dropped toward the river mudflats, the rod struck something dense and rubbery. Years of clotted lard and wool fiber.
Eren set his teeth, driving the rod with three short, powerful thrusts of his hips and shoulders.
There was a wet, sucking thud, followed by a sudden hollow gasp from deep inside the plumbing. A rush of cold, salt-laden river air surged up through the pipe. It carried with it the clear sound of the tide lapping against the timber outfall two hundred yards below. The standing water on the flat stone slabs swirled toward the open hole. It drained away with a satisfying, deep-throated gurgle.
“Drain is clear to the mud,” Eren said. He leaned on the rod and wiping gray sweat from his forehead with the back of his dirty sleeve. “If the arch bleeds water or water drops, it’ll run straight down to the salt reach instead of pooling around our boots.”
“Now the air-flow,” Pella said.
She reached into her apron pocket, took out a stub of animal fat candle. Then she struck a sulfur match against the stone doorframe. The flame sputtered, then caught, casting a warm yellow circle across the damp flags. She set the candle on the floor three feet from the drain. Then she walked to the river wall where a narrow iron louver was rusted shut.
She used an iron wrench. She forced the lever up. The rusted angled slats groaned and opened four inches. That let in a pale knife of daylight and a fresh gust of chilly harbor wind.
Right away, the animal fat flame responded. It didn’t gutter out. Instead, it bent forty degrees toward the disused chimney pipe in the opposite corner. It burned with a sharp, steady hiss. The air was moving in a clean, natural circuit—entering low through the river louver. It swept across the center of the floor. Then it drew upward through the high brick chimney pipe into the kitchen chimney stack.
“Good draft,” Pella noted. She took a notebook and a stub of dark oak-ink from her pouch. “No dead pockets for gas to gather. If Ada’s tools bring across any fumes or steam, the chimney pipe will carry it straight over the rooftops.”
“Right,” Eren said, picking up his five-foot flat ruler and an aged cherry-wood spirit level with brass end-caps. “Now let’s see how much this floor has dropped.”
He laid the ash flat ruler across the center flags where the brass arch would stand. He knelt, sighting along the bottom edge, and cursed softly.
“The two center stones have settled toward the river,” Eren said. “Half an inch on the south corner, three-eighths on the west. If we bolt the baseplates down on this slope, the arch will twist under load. A brass ring under twisting twist is an accident waiting to happen.”
“We lever them,” Pella said.
Together, they drove two iron wedges under the sunken slabs. With Eren hauling on a six-foot oak lever and Pella shoveling dry granite screenings and powdered lime under the edges, they packed the bedding tight. Pella used a square-headed timber tamper. She pounded the crushed stone beneath the slabs until the dust packed into an unbending layer.
When Eren laid the flat ruler back down, the bubble in the glass vial rested dead true between the two brass scribed lines. He struck the center of the slab with his mallet. It gave back a short, flat thud—the sound of solid, unbending bedrock.
“Level as a master’s bench,” Eren said, dusting his palms against his leather apron.
Pella knelt in the center of the cleared space. She drew a red grease pencil from her apron pocket and began laying out the working grid directly onto the dark granite.
She used Hal Rook’s brass measuring tongs and a piece of knotted mason’s twine. She scribed an eight-foot circle on the floor. Within that circle, she marked the exact footprint of the brass arch. Two box-shaped landing pads, three feet four inches apart, lined up exactly with the stonework joints of the wall.
Outside the arch footprint, she drew two heavy white chalk boundaries:
The Worker’s Staging Line: Four feet back. The Emergency Abort Radius: Six feet clear. The Drainage Channel: A two-inch clear hall leading straight to the central floor waste.
“Nothing crosses these red marks except the traveler and their tool roll,” Pella said, her grease pencil screeching against the coarse stone as she finished the outer edge lines. “No extra chairs, no firewood, no soup bowls. If Ada has to step back in a hurry, her boots have to hit clean, dry stone.”
“Fair enough,” Eren said. He walked out to the alley, returning a moment later with the brass arch balanced across his shoulders, his neck muscles straining against the sixty-pound dead weight.
Pella stepped to the riverward side, taking the bottom cross-brace in her calloused hands. “Down slow. Left footplate first. Match the red marks.”
They lowered the heavy brass frame. The cold metal settled onto the scrubbed granite slabs with a heavy, final clink.
For three seconds, nothing moved. The room was cold, gray, and silent, lit up only by the thin daylight from the river angled slats and the flicker of the animal fat candle on the drain rim.
Then, through the soles of Pella’s boots, a sensation rose through the floor.
It wasn’t magic—at least, not the violent, singing magic of the academy summoning rings that set one’s teeth on edge and smelled of lightning. It was a deep, ground-shaking, so low in pitch it was felt in the knees rather than heard in the ears.
The open rune-tracks along the brass casing caught the ringing hum of the river terrace. The weight of the three-story stone kitchen above, the solid bedrock beneath, and the huge, high-pressure pulse of the Gray Rush churning beyond the seawall seemed to seat the arch into the earth itself. The slight metal odor of copper green rust in the room gave way to a clean, bitter-salt smell, like freshly wet mortar settling into a wall.
Eren knelt beside the baseplate, laying his scarred carpenter’s palm flat against the brass.
“It stopped rattling,” he whispered. “When it was on my cart, the brass felt loose, like a dried-out wagon wheel. The moment it touched these flags, it took the weight of the stone.”
Pella stood up, wiping her hands on her canvas apron. Her back ached from the two hours of chiseling, and her knees were stiff and bruised. But the floor was clean, the drain was open, and the boundary lines were clear.
She walked to the wooden shelf beside the door. There, she had set her notebook, an ink pot of dark oak-ink, and a chipped clay pot mug. She lifted the mug. The boiled tea Sister Merrow had given them was lukewarm now, tasting of bitter chicory and river water. But she drank it down to the dregs anyway.
“The room is ready,” Pella said. She looked at the clean red grid on the gray stone. “Now we set the terms.”
