Brask made Orra test the new rig with a barrel full of scrap iron before he would let her near the dive suit.
The barrel hung over the *Morrowfin*’s rail on two separate lines. One ran through the main winch, the other through a block bolted to a different deck beam. Brask leaned over both fittings, pulling each knot hard enough to make the barrel swing.
“Two lines,” he said. “Two anchors. If one fails, the other keeps you from becoming a story we tell badly.”
Vey stood by the windlass hatch, arms folded. “And if either line starts to go, we haul her up. No negotiating with the depths.”
“Understood,” Orra said.
Brask gave the barrel another shove. Both lines took the weight. “You’ve said that before.”
“I’ve learned more since.”
That earned a brief look from him. He nodded once, then went back to checking the rig.
They had used separate beams and separate winches, with enough slack in the backup line for it to catch without yanking Orra sideways. It was a clumsy arrangement, slower than the first, but that was the point. A clean descent mattered less than a safe return. Orra checked the brass suit’s seals, the lamp housing, and the quick-release at her hip. She checked them again while Nima marked the cloudward bearing on her astrolabe.
“Ready?” Vey asked.
Orra looked from the two taut lines to the secured windlass. The iron pawl was engaged. The keel-instrument rested in its case, well away from the mechanism.
“Ready.”
The island’s underside came into view in fragments as the crew lowered her through the open ring. Black stone, then the descending chain, then the huge curve of the structure beneath it. The Aethersea glowed around the stones in long bands of green and violet. It made the chain shine as if it had been drawn through liquid light, though Orra knew better than to imagine it touching anything like water.
Her suit kept the mist out. The pressure of the depths still made itself known through the brass joints and the ache in her fingers.
“Main line steady,” Brask called through the speaking tube. His voice arrived roughened by distance. “Backup taking a little weight. You feel that?”
“Barely.”
“Barely is where trouble starts.”
Orra turned her helmet lamp toward the stone ring. Last time, the jolt had come from somewhere beyond it, a sharp tug that had dragged her against the chain. Now she moved carefully, testing the line as she went. The ring was broad enough to pass a house through. Its outer edge had been worn smooth, but the stone beyond it was scored with narrow grooves that followed the chain into the structure’s seam.
Next
With the chain anchored in the structure and the windlass shifting under an answering pulse, the crew must decide how to trace the new bearing without triggering another pull.
She stopped at the lip and examined the grooves. They were no random cracks. Each cut ran in the direction of the chain’s pull, guiding it deeper into the curved mass. The chain did not vanish into a gap. It entered a fitted channel.
“Brask, I’m at the seam. Chain’s guided into a track.”
“Can you see where it ends?”
“Not yet.”
Orra eased along the channel. The opening widened enough for her to pass through sideways. Inside, the stone curved around her in a hollow chamber, its walls ribbed like the inside of some vast shell. The chain crossed the chamber and disappeared into a thick collar set into the far wall.
She brought the lamp close. The collar was made of metal darker than the chain, its surface marked with a repeating pattern of shallow cuts. A pin as thick as her leg ran through the final link and into two brackets built directly into the stone.
The chain ended there.
Orra stared at the pin. The black-stone ring outside was only a guide. The chain’s weight was caught by the structure itself, anchored in the collar and locked into the stone ribs around it. Whatever the chain did above or below, this immense thing was holding it fast.
“Found the end,” she said. “It’s fixed in a collar inside the structure. The chain’s anchored here.”
A small burst of static came through the speaking tube before Nima answered. “I have you. That’s a real anchor?”
“Pin through the terminal link. Two stone brackets. It’s not passing through.”
“Then the structure holds the chain.”
“Yes.”
The answer settled into Orra with the weight of something she could finally inspect. It did not tell her what the chain held, or why the hidden island’s windlass could pull it. But it ruled out one dangerous guess: the chain was not simply suspending this structure beneath the island.
She turned her lamp across the chamber. The ribs curved out of sight on both sides. Near the anchor collar, she saw a narrow row of pale marks in the stone. They pulsed faintly, one after another, running from the collar toward the upper part of the structure.
“Nima,” she said. “I’ve got light moving along the ribs. From the anchor, heading up.”
“Hold where you are. The astrolabe is moving.”
Orra braced one glove against the wall. The pulse reached the stone around her. A low vibration passed through the suit and into her palm. The chain trembled in the collar, too slightly to shift, but enough for her to feel the strain change.
Above, Nima’s voice came sharp through the tube. “The signal’s coming from below. It matches the cloudward pulse, and I’m reading the same rise along the chain. It’s traveling up.”
Orra looked back toward the channel. The light marks had gone dark. For several seconds, there was only the faint glow of the Aethersea beyond the opening.
Then a second pulse came down.
It was weaker, but the collar answered with a hard metallic knock. Orra felt it in her knees. The chain snapped taut, and the whole chamber shuddered.
“Orra, report!” Vey called.
Her main tether swung sideways. The lamp struck the stone, and its bracket broke. Her light spun away, bouncing twice before it vanished into a crack. Darkness swallowed the chamber except for the thin colors outside the seam.
The backup line caught her with a wrench that drove her shoulder into the wall. Pain flashed down her arm. She reached for the speaking tube, fingers finding the grille by touch.
“I’m held,” she said. Her voice came out tight. “The chamber moved.”
“Are you injured?” Brask asked.
“Shoulder. I can use it.”
“Don’t prove anything to the stone. We’re hauling you.”
The chain still strained against its collar. Orra found the main line by feel and saw its faint indicator-glow wavering near the channel. The backup had kept her from being thrown against the chain, but the first line was fouled against a sharp lip in the passage. She could wait for the crew to haul on it and risk a worse snag, or free it before the strain pulled her back into the chamber.
“Hold both lines,” she called. “Don’t haul yet.”
She moved slowly, working the tether off the lip with her good hand. The backup line took her weight. Once the main line came free, she gave the signal to recover.
The journey up was measured and unsteady. Brask kept both lines under tension, adjusting each winch in turns. Nima called out the second pulse’s fading pattern as it traveled away through the astrolabe, and Vey kept the *Morrowfin* steady above the ring. When Orra’s helmet broke the surface of the hatch, Brask was waiting with both hands on the suit.
He helped her sit, then took the cracked lamp from her shoulder. “You got your answer.”
“Part of it.” Orra rolled her aching shoulder carefully. “The structure holds the chain. And its pulse went up.”
Nima stepped over from the astrolabe, face pale with concentration. “The return came from beyond the cloudbank. It came down the same path.”
“So something up there heard it,” Vey said.
“I can’t tell whether it was the marker or another source,” Nima said. “But the response was strong enough to reach the anchor.”
Brask glanced at the windlass. The pawl remained in place, but the chain’s upper links had shifted a fraction against it. The scrape was fresh and bright against the old metal.
Vey’s gaze stayed on that mark. “No one touches the instrument to the windlass. Not until we know what that reply does next.”
Orra looked at the two lines still stretched across the hatch. The backup had held. The main line was scraped where it caught the stone, and her shoulder would need a day before it stopped complaining. Neither was a price she regretted paying. The collar had given them an answer they could trust, and the response had come back with enough force to move a chain locked behind an iron pawl.
Nima bent over the astrolabe again. “The bearing’s changed. The reply didn’t come from the old cloudward mark.”
Vey turned to her. “Can you place it?”
“Not yet. But it’s closer to the far side of the cloudbank than our first reading.”
Orra looked at the fresh scrape on the chain. Whatever had answered them had done more than echo a signal. It had pulled back.
