Frederick did not like the sound the launch made when the world gave way under it.
Wood should creak. Rope should strain. Iron should complain in notes a man could sort if he had time.
This was none of those.
The hull passed over the smooth black oval and the whole boat gave one flat, depthless groan, as if something larger than seawater had taken hold of it and was deciding which half belonged where.
"Hold her straight," Frederick snapped.
Ezekiel, white-knuckled at the tiller, gave him a look fit for a condemned man.
"Straight where?"
"If I knew that, I'd be charging more."
The bow dipped.
Not down.
Sideways. Forward. Through.
Frederick caught the cradle frame with both hands just as the launch lurched hard enough to slam his hip into the bench rail. The smooth black surface around them swallowed the chop, the spray, and the night wind all at once. For half a breath there was only the boat, the wrong dark, and the ringing of metal with no air in it.
Void moved first.
He stepped across the deck as if the tilt meant nothing and put one hand on the mast post. The boat stopped rolling. Not entirely. Just enough to keep the cradle from ripping free and taking Frederick with it.
"Now," Void said.
That was to Frederick, which was correct.
"Ezekiel, aft lashings. Cut the upper pair. Leave the cradle line."
"The boat is falling."
"So move faster."
Ezekiel moved.
Good boy. Frightened, clumsy, and still moving. Frederick could work with that.
He dropped to one knee by the battery frame, tore the feed clamp loose, and dragged the resonance needle housing clear before the next shudder could send it across the deck. The black pin inside the scored brass ring spun once, struck east, and held there with such force the whole instrument hummed against his palm.
Useful.
Terrible, but useful.
The launch hit something that felt like water pretending to be stone.
Frederick went flat across the planks. Behind him Ezekiel yelped, the mast gave a crack like a split wrist, and the descent cradle slammed down into its guide braces with enough force to bend one hook and shear another.
Then the motion stopped.
Not gently.
Stopped.
Frederick pushed himself up coughing brine that did not taste like sea. The air was colder here, thinner too, with a metal edge at the back of the throat. Above them hung a black vaulted surface rippling from no wind at all. Far beyond it, faint and distorted, something moved with the size and slowness of deep-water life.
Ezekiel stared straight up.
"Father."
"I can see it."
"That looks like the sea."
"It is the sea," Void said. "Above us."
Ezekiel looked down very carefully, as if checking whether his legs had remained loyal.
"I preferred it when up was up."
Frederick got to his feet and took stock.
The launch had grounded on a strand of dark gravel and salt-white stone inside a cavern broad enough to swallow the harbor that birthed him. One side of the hull had split along the lower seam, but the keel held. The mast leaned at an angle that would have shamed any honest carpenter. The cradle was intact except for the bent hook. The battery frame had cracked one corner bracket. The spare chest had burst open and strewn clamps, hooks, and iron teeth across the black shore like someone had vomited a forge.
Could have been worse.
That irritated Frederick immediately. If it could have been worse, then it could also have been better.
"Don't just gape," he said. "Get the chest shut before we lose anything clever."
Ezekiel blinked once and bent to it.
Void had not moved from the mast post. He was looking past the grounded launch and into the plane proper, where ridges of black stone lifted out of pale grass and shallow silver pools that did not reflect them correctly.
Frederick followed his gaze and felt his mind try to reject what his eyes were doing.
Things were farther away than they looked. No, nearer. No, both, depending on whether he watched the stone or the shadows under it.
He hated that at once.
He pulled the compass from his belt. The needle spun uselessly. He checked the resonance housing instead. The black pin still held east.
Good. One thing in this miserable place could still tell the truth badly.
"How long does the route stay open?" Frederick asked.
"Long enough for one more mistake," Void said.
"By whose count?"
"Mine."
That was not a comforting system.
Frederick stepped over the split bench rail and dropped onto the salt-streaked strand. The ground held. So did the second step. On the third, the nails in the torn hull behind him all gave a thin answering tick, and he stopped.
Not fear.
Pattern.
He crouched, picked up a loose clamp from the open chest, and tossed it toward a patch of pale ground ten feet ahead.
The clamp struck, bounced once, and vanished straight down through the pale skin into black water below with barely a sound.
Ezekiel swore.
The surface there settled into itself again, looking no more suspicious than before.
"What in the name of-"
"Not ground," Frederick said.
Void came off the boat then, stepping wide of the false patch without looking at it. That annoyed Frederick too.
"A split layer," Void said. "Water wearing a skin of stone."
"You knew that already?"
"I know it now."
Frederick almost snapped something useless at him, then didn't, because the distinction mattered.
This place was not random.
It was actively bad in specific ways.
That meant it could be read.
Ezekiel hauled the chest shut and dragged it to the shore with both hands.
"If the floor can decide not to be floor, I'd like to return to the boat."
"The boat is half in the threshold still," Void said. "If it goes, everything left on it goes with it."
That got Ezekiel moving again.
Together, under Frederick's directions and Void's increasingly narrow patience, they stripped the launch of what mattered most. Battery frame first. Needle housing. Depth reel. Coiled ropes. Tool wrap. Food pouch. Oilcloth packet of route notes that Frederick checked twice because stupidity often arrived from inside. The cradle last.
That nearly killed the schedule.
It took Frederick and Ezekiel both to free the bent hook, and even then the cradle shifted wrong, dragging its weight toward the black water overhead instead of toward the shore. Ezekiel hissed when the pull hit the shoulder the wardens had already half-ruined, then hauled harder anyway.
"Stop pulling against it," Frederick said. "Feel where it's going stupid."
"That is not an instruction."
"It's the only good one I have."
Void took the far brace with one hand.
No strain in his face. No show in it either. Just force applied at the correct point, enough to cancel the bad drift and no more.
Useful again, Frederick thought, which was beginning to become a habit.
They got the cradle down onto real stone just as the threshold behind the launch narrowed by a hand's width. The black oval overhead tightened. The part of the hull still caught under it gave one hard splintering crack.
Ezekiel turned toward it at once.
"Do we cut the boat loose?"
"From what?" Frederick asked. "A bad idea?"
Void answered instead.
"Leave it. If the route opens this way again, we may still want what survives."
May. Frederick disliked may almost as much as debt.
He set the resonance housing on the ground, rotated the brass ring, and watched the black pin jerk toward the interior ridge line. Not toward the threshold behind them. Not toward the false ground. Forward.
Of course it was forward.
There was never a profitable mystery behind a man.
"We move that way," Frederick said.
Ezekiel looked at the ridge, then at the silver pools scattered beneath it.
"And how do we know what's real?"
Frederick pointed to the needle.
"We ask the needle."
That got him a look from Void that might have been approval if one were feeling charitable.
They set off with the cradle between Frederick and Ezekiel and the battery frame strapped crooked on top. The plane fought them for every yard. Sound went wrong first. Their steps landed close and arrived late. Then the distance of things kept slipping. A jag of black rock seemed a sprint away until they tried to reach it and found themselves walking toward it for three times too long.
Ezekiel was the first to notice the second rule.
"Stop," he said sharply.
Frederick stopped because the boy did not use that tone for nothing anymore.
Ezekiel pointed with his chin.
"That grass is humming."
Frederick heard it then, faint and fine, not from the grass itself but from the iron buckle near Ezekiel's knee answering something beneath it. He crouched, held the loose hook low, and the metal immediately filmed white with frost.
"Good," he muttered.
"Good?" Ezekiel said.
"It only wants the metal."
"That was the good outcome?"
"You were standing next to it, weren't you?"
They swung wide around the patch.
Void spoke without slowing.
"Remember it. Local laws sit closer to the surface here. Anything ordinary can turn conditional."
That was the first real explanation he had offered since the threshold, and Frederick resented how useful it was.
"Conditional," Ezekiel repeated. "That's a miserable word."
"It gets worse," Void said.
Frederick believed him immediately.
The ridge turned out to be closer than it had looked and lower than it had looked and harder to climb than either, which Frederick took as further proof that this plane was built wrong. Halfway up, the cradle rang once against the stone and every silver pool below them answered with a ripple against no wind.
Ezekiel nearly dropped his side.
"Tell me that wasn't important."
"It was important," Frederick said. "Keep lifting."
At the top of the rise he finally saw the pattern whole.
The false ground, the frost patches, the delayed sound, the pull on the needle, even the threshold itself. They all leaned toward a shallow basin cut into the black stone on the far side of the ridge. It might once have been a dry bowl. It was not dry now.
Something moved at its center.
Not water. Not light. Not either one cleanly.
The surface turned without spilling, pale bands winding through darker ones, every color reduced to metal, salt, and cold fire. The air above it bent in thin trembling layers. Frederick felt the hair on both arms lift inside his wet sleeves.
The resonance needle snapped toward the basin so hard the brass ring bit his thumb.
Ezekiel saw it, then saw the basin, and forgot to complain.
That alone gave the thing weight.
Void stopped beside Frederick and looked down into it as if he had expected the pool and still found the exact shape inconvenient.
"So," Frederick said, quieter than before.
"Yes," Void said.
Ezekiel swallowed hard.
"What is it?"
Void did not look away from the turning surface below.
"A law pool," he said. "If it takes you, it changes you."
