“Is this all real, or—”

“A mix,” said Arjun, “of stuff they’ve actually built and renderings of what they imagine.”

“And has this actually been made public or—”

“Broadcast six hours ago,” he said. “It is a huge reveal.” Never before had Red divulged any pictures — real or imagined — of the inside of the Kulak.

By now the fly-through had reached the far end, and she could see space opening up around her as the povv exited from the Kulak’s maw. The familiar sight of the habitat ring became visible, sweeping around in both directions to enclose the blue Earth in its jeweled embrace. From the system of rigging woven around the iron fist, a cable descended straight to the equator. Slowly at first, then building speed, the povv descended, achieving in a few seconds what would have taken several days in any kind of realistic elevator. Even through a screen of bright clouds Kathree could pick out the complex landforms of Southeast Asia to the north and, to the south, the huge dun slab of Australia, now joined to New Guinea by a lumpy gray-green tendril. The povv chose to zoom down on that first, coming close enough that it became possible to see a road traversing the land bridge. Then it veered and banked onto a northwesterly course, following the green, steaming spine of New Guinea to the cape at its end, where it nearly touched the equator. There, construction was visible: cleared land, buildings, excavations, a hazy web of infrastructure, glimpsed but not lingered on. The povv soared out over a turquoise sea cluttered with landforms she recognized vaguely from having seen them on maps. But after a few moments her eye was drawn to something that was flagrantly unnatural, looking as if it had been drawn in with a ruler and a pencil: the tether from the Kulak, plunging vertically into the ocean between two big islands. These, she realized, had to be Borneo and Sulawesi, and the water between them the Makassar Strait. The povv’s movement slowed, then stopped. The symphony and the choir were laboring through a slow crescendo. A change, more felt than seen, came over the display: the programmed camera movement was finished and the varp was now responding once again to Kathree’s movements. Like a giantess bestriding the strait, she could move around and look at it from different angles. For a moment nothing really happened. Then her eye picked up turbulence in the sea, around where the tether stabbed into it. The surface was welling up and foaming. The tiny wrinkles of normal surface waves were erased, replaced by vast green whorls and galactic arms of swirling foam. Bending forward she saw angry gulls wheeling about. That detail convinced her that what she was seeing was real — not a rendering. The disturbed region grew north and south, spreading away from the cable — which she knew to be on the equator — without growing east-west. The cable forked, then forked again, becoming a fan that broadened north and south to support the full length of whatever was roiling the strait.

It erupted from the surface first at the equator, then proceeded to rip a gash in the sea that spread up and down the meridian with immense velocity. The object could hardly be observed at first for all the water draining from it, plunging in multiple Niagaras back into the sea and hurling up a storm front of spray that rose higher than the structure itself. But in a minute the Gnomon became visible. Kathree had to back away to get a picture of the whole length of it. She extended her left hand and made a counterclockwise knob-twiddling gesture, reducing the volume of the Kyoto Philharmonic’s brass section before the bass trombones and kettledrums imploded her skull.

If the designers of the Gnomon had intended to make the anti-Cradle, they could hardly have done better. It had the long wicked curve of a katana — the better to follow the curvature of the Earth — combined with the translucent delicacy of an insect’s exoskeleton. Indeed, it seemed to be unfolding, reshaping itself as it rose into the air, an origami praying mantis molting into a larger body. Its manifold corrugations and arching carapaces spoke of a million Jinns toiling in cubicles for centuries to build the strongest thing they could imagine with minimum weight.

“What’s it made of?”

“Carbon and magnesium, mostly,” said Arjun. “Two light, strong materials that can be extracted from ocean sediments.”

“Is that how they did it?”

“Yes,” said Cantabrigia Five.

“Energy intensive,” Arjun remarked. “They ran power down the tether to a production facility on the ocean floor.”

“They had workers living on the ocean floor?”

“Robots.”

“And therein lies an opportunity,” said Cantabrigia Five.

The producers of this spectacle had once again seized control of the povv and begun taking Kathree on a forced march up the length of the Gnomon, slowing down to linger on the good bits and zooming past what was repetitive. She got the idea, which was that it had a sort of carriage that could move north-south on a giant rail and connect with the ground along a range of latitudes. That it had its own internal train lines connecting residential pods, military installations, luxury resorts for the whole family, and so much more. It was obviously rendered — stuff that hadn’t actually been built yet. Her inability to control what the povv was doing made her a little queasy. She levered the earbuds up, closed her eyes, and carefully pulled the varp away from her face. Then she opened her eyes on reality: the beach, the islet, her two interlocutors. She handed the varp back. “What sort of opportunity?”

“If you are going to make first contact with an intelligent alien race,” said Cantabrigia Five, “dropping huge strip-mining robots into their homeland might not be your best move.”

Kathree pondered that one for a bit. “Ah,” she said.

“Yes.”

“So there’s a reason they were so keen to make nice with the Diggers.”

“Having fucked it up spectacularly with the Pingers. Yes.” Cantabrigia Five stared at her for a little while. Her silence and her gaze were impressive, yet Kathree did not feel wholly uncomfortable.

Finally she went on: “Actions taken here today will cast long shadows into the future of New Earth. With more resources here, we might have effected a more elaborate strategy, with less uncertainty. But the mere fact of having had more would have spoiled it.”

“HOW DID YOU GUYS COME UP WITH ALL THIS?” TY ASKED.

He was squatting on the islet next to the Cyc, who was still swaddled in sleeping bags, only her hands and head exposed. She was holding an instruction manual, angling it toward the light of the flynk chain. This was still illuminating the cove, but the crew of Ark Darwin had dimmed it so that people could sleep. She had to focus intensely to read the words, many of which must be unfamiliar to her. Her lips moved slightly as she parsed unfamiliar Cyrillic characters sprinkled through almost every word. Headphones buried her ears in great donuts of foam. She hadn’t heard Ty, didn’t know he was looking at her. So he had his fill of looking for a minute. She wasn’t his type, and anyway she was very young. But he was beginning to see what Einstein saw in her. Einstein had to know that there was nobody for him on his RIZ, no Indigen girl he could have an interesting conversation with. And yet if he were to somehow find his way to the habitat ring, he’d be looked on by all the smart girls there as a hillbilly.

The device in the box was a portable sonar rig. It was capable of sending out pings, but that wasn’t how they were using it. They were using it to listen. Sonar Taxlaw had virtually wrenched it from Ty’s grasp and mastered it. The arrival of Ark Darwin and the movements of the boats and the barge had caused her no end of annoyance, but with a little encouragement from Ty, she’d begun to see it as an interesting science experiment, a way of understanding what those technologies must sound like to Pingers and other mammals that frequented the deep.

Moving carefully on the steep, glassy surface of the islet, he edged into her peripheral vision and gave her a light tap on the shoulder. He hated to break her out of her reverie, but there were questions he needed answered. She was stunned for a moment, as if she’d just been teleported into this location from a thousand miles away, but rapidly she came around and pulled one of the headphones away from her ear. “Come again?”

“All of this.” Ty rested a hand on the battered plate atop the pipe, nodded toward the makeshift sledgehammer. “How did you come up with it? How do the Pingers know that when they want to talk to you they should build a cairn on the beach at such-and-such place?”

“We began sending out scout parties as soon as the atmosphere became breathable,” Sonar said.

“That’d be three hundred years ago,” Ty said.

“Two hundred and eighty-two.”

“Just making the point that this is old history.”

“Not that old.”

Ty heaved a sigh. “Not within living memory.”

“It is not merely an oral tradition, if that’s what you’re getting at,” Sonar said. “We maintain written records.”

“On one hundred percent cotton paper. Yes. Go on.”

“There was nothing for the scouts to eat, of course. So they could only range as far as they could go with food that they carried on their backs. But in time they discovered edible seaweed and bivalves along the coast.”

Ty nodded. “Once TerReForm’s engineered algae had done its job of building the atmosphere, it needed to be held in check. TerReForm seeded the coasts with filter feeders and the oceans with krill.”
