The shaft made an impenetrably dark hole in the water, unlit, possibly leading nowhere—except that a tickle of air teased Hayden's brow, and his bike was slowly being sucked inward.
"We're wasting time." Carrier kicked forward, his foot-fins driving him quickly into the dark. Hayden flipped off the bike and gestured for Martor to follow. Mahallan was already inside the tunnel, flanked by the carpenters.
Inside there was little to tell they were entering a world of water. The tunnel was a lattice of beams, like those of any freefall scaffold. The surface stretched between them could have been stone in the dimness of lamplight. Only the clammy chill suggested the nearby presence of the sea.
"I would have thought the walls would bulge inward or something," said Mahallan. "But of course they don't. No gravity, no pressure."
"I've heard that word before," said Martor in an overly casual way. "Gravity. Spin makes it, right?"
Mahallan had been doing a hand-over-hand walk along the struts. Now she stopped to look at Martor, and in the dim light he saw her eyes had gone wide. "Sometimes I forget," she murmured, "that the strangest of things here are the ones I talk to."
"Now what's that supposed to mean?" But she had turned away already. Ahead, Carrier shouted for them to be quiet.
He was silhouetted by flickering lamplight from a number of fan-driven lanterns. Beyond him the tunnel opened up into a broad space—a cubic chamber walled in wax paper and about forty feet on a side. This was a hangar, Hayden realized, for it was filled with bikes and other flying devices. The air here was cold and damp but the six men who were pointing their rifles at the newcomers didn't seem to feel it. They were uniformly dressed in dark leathers, and their narrow pale faces had the sameness of kin. It seemed like a small welcoming committee, but Hayden was sure that the faint motion of the paper walls next to him indicated more men hiding in the water outside.
"State your business," said their leader, who was clearly the oldest. The father of the others, perhaps?
"Trade," said Carrier. "Carpentry supplies. We can pay you whatever you think is appropriate."
"We're not trading," said the older man. "Be on your way."
There was a momentary silence; Carrier hung perfectly still. "What now?" Mahallan whispered to Hayden. "Does he threaten them?"
Hayden shook his head. "It's hardly worth our while to fight a pitched battle for some nails and wood, and they know it. I don't know what he'll—" He stopped, because Carrier was speaking again.
"As you can plainly see," he said, "our charting expedition is well-enough supplied that we don't need your help. But it'll shorten our stay if you do help us."
"Charting?" The older man looked alarmed. "Charting what?"
"Oh, just the various objects in this part of winter," said Carrier with a negligent wave of his hand. "Forests, rocks, lakes—anything that might drift into our space someday. Or that might be useful or militarily significant."
"We're of no use to nobody," said the leader. He was visibly tense now. "We want to be left alone."
"Well, then," purred Carrier, "I'm sure our captain could be persuaded to leave one or two objects off of the charts. If, that is, we received something in return."
"Wait here." The man turned and left through a prosaic-looking door that opened out of the hangar's far wall. A few minutes later he returned, looking unhappy. "Come ahead," he said. "You can trade."
So it was that they entered Warea and learned how the cast-out and the fugitive lived in the empty spaces between the nations. The walls of the short corridor between the hangar and the town complex glowed from distant lamplight; long shadows cast on the paper walls suggested some sort of layered barrier between the cold of the sea and the town. In fact as they passed through the next door the temperature rose and the dampness receded. The silhouetted bodies of the people in front of Hayden split off one by one, opening more and more of the space to his view until he was there himself, gaping about at the cave that was Warea.
Mostly it was just a cube like the hangar, but several hundred feet across. Floating in this space in a disorganized jumble were various multisided houses, each one tethered to its neighbors or the space's outer struts. Numerous openings led off from the main cube, some terminating almost immediately in walls of gelid water, others twisting away, their lamplit outlines faintly visible through the paper walls of the cave. The place reeked of burning kerosene and rot but it was reasonably warm, and the big industrial lanterns with their grumbling fans at least prevented an aura of total gloom from overtaking the citizens.
Some of these were staring in open hostility as Carrier led his group into their crowded airspace. The town elders who had decreed that they could enter had discretely retreated, or chose to remain anonymous within the mass of people. Carrier stopped to ask directions and while he did, Hayden examined the people. They had a familiar look: sallow, overstretched, and glum. For the most part they were exiles who remembered growing up within the light of a sun. Unhappy they might be, but few of them showed the signs of weight-deprivation.
In a few minutes he saw why. The far wall of the cube was moving—swinging up and to the left with a constant rumble that quivered the walls. The cube was only part of Warea. An entire town was embedded in the sea, and on part of its rotation the wheel passed through the cube like a giant saw cutting into a block of wood. Hayden watched houses, shops, and markets pop out of the cube's wall and swing up to vanish through the ceiling in steady and relentless motion.
"It's not a small place," muttered Carrier. "There's two markets. Dry goods on the wheel, Armorer. Building materials here."
"We'll split up, then," said Mahallan helpfully.
"I'll join you in a few minutes," said Carrier with a disapproving frown. "Watch yourselves."
Hayden, Martor, and the armorer watched the others vanish into a cloud of people in the building market. The place was crowded with huge baskets filled with white bricks and beams. "Looks like they'll find what they need right off," said Mahallan worriedly. "Let's hurry, we wouldn't want to keep them waiting."
Hayden shrugged and turned to coast in the direction of the wheel's axis. "I didn't see any wood back there," he commented.
"But what was all that white stuff?"
"Same as these houses are built with." He did a course correction by slapping one on the way by. Its white brick surface undulated slightly. "Paper. They fold origami bricks and beams in triangular sections and then fill them with water. You get beams and bricks that are stiff and incompressible."
"Really?" She seemed inclined to stop and admire the buildings. Hayden pressed on; now that he'd escaped Carrier's roving eye, he could run an errand of his own.
Mahallan and Martor caught up to him as he was entering the big barrel-shaped axis of the wheel. A sullen local flapped by on ragged foot-wings, and the armorer watched him go. "Who are these people?" she asked. "They don't seem happy to see us."
"Refugees, most of them," he said. "A lot of them will be from Aerie, which was conquered by Slipstream about ten years ago. And some are pirates."
"This is a pirate town?" Mahallan laughed in apparent delight as they hand-walked down the top few yards of the yin-yang staircase that led to the rim of the wheel.
Where the curve of the staircase began to flatten out the rungs of the staircase were replaced with steps, at first improbably tall ones. As Hayden flipped over and began using his feet he said, "You asked who these people are. Can I ask who you are?You don't seem to know the first thing about how the world operates, and yet you're our armorer. That's more than a little…"
