The King Who Broke Heaven’s Tithe

Chapter 16 The Passage That Drank

Daren found the current with a handful of sawdust.

He scattered it across the mill chamber’s water and watched the pale flecks drift toward a narrow opening behind the turning wheel. Every seventh revolution, the flecks stopped, trembled, and vanished into darkness.

Tovin crouched on the stair above him.

“It started after they moved the stones at the gate.”

“You stayed out of it?”

“Yes.”

Daren looked at the boy’s wet boots.

“I stood on the second step. The water rose.”

Brida lowered a measuring rod beside him. A fresh line on the stone confirmed it.

“Good,” Daren said. “Keep noticing things. Keep telling us before you follow them.”

He had wanted a rest. He had slept for an hour after the meal and woken with his shoulder stiff enough to make dressing a negotiation.

The fort had chosen a poor time to develop lungs.

They stopped the wheel with the repaired sluice rather than wedging its blades. Selka stood at the stair with a lantern while Brida searched the wall for a maintenance hatch.

Tovin found the hinge first.

It had been disguised by a sheet of mineral deposits. He recognized the pin because the mill in Bracken used a smaller version to keep grit out of its axle bearings.

Brida loosened it with a chisel.

A narrow door opened inward.

The passage beyond was dry above ankle height and smelled of copper coins.

Daren touched the doorframe with his scar.

A tired voice stirred inside it.

Leave room for the next pair of hands.

Nothing else came.

“No warning?” Brida asked.

“Advice.”

“That would be a first.”

She tied a rope around Daren’s waist. He insisted she take the other end and remain at the entrance. There was no sense putting every person who understood the fort inside the same trap.

Selka followed him with the lantern.

They moved sideways between channels set into the walls. Some were pottery, some copper. One carried warm air from the mill toward the hall. Another returned cooler air in the opposite direction.

The fort had once moved its heat carefully, saving what a simple hearth lost through a chimney.

Farther in, the channels joined a round chamber.

Three stone benches surrounded a shallow basin. Above it hung a bronze ring with inward-pointing teeth.

Daren thought of the fragment Brida had found in the arch.

The same teeth. The same metal.

Selka raised the lantern.

“These were here before the sect used the conduits.”

“How can you tell?”

She pointed to a carved border partly hidden beneath newer plaster. The old pattern showed hands passing a bowl. The seven rays had been stamped across it later.

Daren touched the basin.

Warmth entered his fingers, followed by an impression of slow breathing. People had rested here after work. He felt fatigue loosen, then the memory thinned into nothing.

“This gave something back,” he said.

Selka studied the bronze ring.

“Until someone turned it around.”

A thread of gold moved along its inner edge.

Daren withdrew his hand.

The ring clicked.

Water rushed through the channels behind them. Selka turned as the lantern flame bent toward the basin.

“Out.”

They had taken two steps when bronze strips unfolded from the wall.

One caught Daren’s sleeve.

He tore free, leaving cloth behind. The strip curled around it and drew it toward the basin. There were more strips now, thin as reeds, searching the air.

Selka struck one with the lantern hook. It bent, sprang back, and wrapped around the iron.

She let go.

Darkness swallowed them.

Daren felt the rope tighten.

“Follow it,” he said.

Her hand found his belt. They staggered toward Brida’s light as something scraped over the stones behind them.

The rope jerked hard enough to hurt his ribs.

He was grateful for every inch.

They fell through the hatch. Brida slammed it, and Tovin drove the hinge pin home with a stone.

A bronze strip struck the other side.

Then the sound stopped.

The water in the mill chamber began to fall.

Daren sat on the stair, breathing through his teeth. Selka’s hand was still locked around his belt. She released it slowly.

“Not lungs,” she said.

“No.”

Brida looked from their torn clothes to the sealed hatch.

“Can it reach the hall?”

Daren pictured the warm-air channel climbing toward the hearth.

He wanted to say no.

“We have to block the upper vents until we know.”

Tovin stared at the door.

“There was a lever beside the hinge.”

“You saw it?”

“When it closed. There were two marks. A bowl and a mountain.”

Daren looked at Selka.

“Which way was it pointing?”

“Mountain,” the boy said.

Brida scraped the deposits away with her chisel. The lever lay outside the hatch, close enough to reach without opening it. Its handle pointed toward a worn image of seven peaks.

She moved it toward the bowl.

The water stopped falling. From the other side of the door came a final metallic rustle, then silence.

Nobody celebrated.

They waited through twenty turns of the wheel after reopening the sluice. Tovin marked each turn with a pebble. When the level remained steady, Brida drilled a shallow hole through the lever’s wooden grip and pinned it against the frame.

“A precaution,” she said. “Not a repair.”

Daren agreed. They would block the upper vents anyway. He could explain the loss of heat; he could not explain away someone dying because they had trusted one old handle.

He looked back at Tovin.

“Next time it changes,” he said, “you come straight to us.”

The boy nodded, watching the pin.
