Vortex

Of course I was protected in the most basic sense. Like Turk, I had passed through the temporal Arch. For ten thousand years I had been a memory in the archival functions of the Hypotheticals, and they had re-created me in the Equatorian desert because that was the business of the temporal Arches: to faithfully reconstruct certain information-dense structures so that the data they contained could be used to correct errors that might have crept into local systems. It was a homeostatic mechanism, nothing more.

The disassemblers wouldn’t touch my body because I had been tagged as useful. But that protection would be worthless if Vox dissolved into its component molecules. I needed to be able to exercise conscious control over what the machines were doing.

My best opportunity lay with the Coryphaeus. The processors that constituted the Coryphaeus were heavily protected. Even the nuclear detonation that had brought down the Network had not destroyed these devices, only damaged their interface with the physical world. The disassemblers would surely devour them, but not until most of Vox Core had been pulled apart. Much of my consciousness was already embedded in these processors. The same inhibitions that prevented the disassemblers from dismantling my body might extend to the Coryphaeus’s hardware, or could be made to—or so I hoped.

The Network began to fail as the citizens of Vox died in significant numbers, and I exploited that terrible opportunity. I used dormant processors to analyze the signaling protocols of the Hypothetical machines. I linked those protocols and signaling mechanisms into the deeply nested feedback cycles of the Coryphaeus, allowing me some measure of control.

And as Vox was sterilized of human life, the Coryphaeus became a chorus of one. I became the Coryphaeus.

Once I had decoded the procedural logic of the disassemblers, it became possible to feed them false recognition signals. They promptly abandoned the deconstruction of Vox Core. I used subtler and more potent instructions to reduce them to dormancy. They lost all organizing cohesion and fell from the air like dust.

But it was too late for the inhabitants, and nearly too late for the upper levels of Vox Core, which had been eroded to a skeletal framework of girders and fractured cladding. I was able to reseal the inner portions of the city and repair the relatively minor damage to the engine decks, using a combination of robotic devices and co-opted disassembler flocks. I allowed the disassemblers to dispose of all human remains, leaving nothing half consumed.

By the time I restored the city’s lights, the corridors and tiers and plains of the city were as empty as if they had never been inhabited. The air-circulation system eventually seined away any remaining dust.

But that wasn’t all I could do, I discovered.

As I waited for Turk and Allison to return—as I hoped they would—I began to explore the newly porous borderland between the Coryphaeus and the Hypotheticals. Before long I was tapping into systems larger than the Earth itself. All Hypothetical devices were interconnected, in nested hierarchies that reached from tiny disassemblers to archival machine flocks in translunar orbit, energy-mining mechanisms in the heliosphere of the sun, signal transducers in the outer solar system, transducers circling nearby stars. All these I could now perceive and influence.

I devised filters to compress this flood of information into intelligible packets, making the secrets of the Hypotheticals small enough that I could contain them. And making myself larger in the process.

My physical body began to seem redundant, and I thought about allowing it to die. But I would need it, I thought, to interact with Turk and Allison, if and when they came back. What they found here would be difficult for them to accept, and what I planned to do next would be difficult to explain.

Over the course of their multibillion-year evolution the Hypotheticals had learned to exploit a capability they had never acquired for themselves: agency.

Agency—that is, volitional action aimed at achieving conscious ends—had arisen only sporadically in the galaxy, mostly in the climax ecologies of biologically active planets orbiting hospitable stars. Species capable of agency seldom lasted longer than it took them to overload and overwhelm their planetary ecologies. They were, as the stars measure time, an unstable and ephemeral phenomenon.

But it was just such a species that had created the self-reproducing machines that were the first progenitors of the Hypotheticals. And these blooms of organic sentience were unfailingly useful: they generated unusual information; they concentrated valuable resources in their ruins; often they launched new waves of replicators, which could be harvested or absorbed into larger networks.

In time the Hypotheticals began to actively cultivate organic civilizations.

There was no agency in this, only a blind acquisitiveness. The Hypotheticals evolved in ways that maximized their exploitation of sentient organisms. Early in the history of the galaxy, an organic civilization had constructed twin Arches in order to colonize the marginally habitable planet of a neighboring star—the species suffered decline and extinction soon after, but its technology was analyzed and adopted by the Hypotheticals. In the same way the Hypotheticals had learned to extract energy from stellar cores and gravity gradients, to manipulate atomic and molecular bonds, to order and stabilize the exchange of information over distances of hundreds of light years. Eventually the Hypotheticals had developed a means of extending the useful life of such species. If a fecund mother planet was suspended inside a temporal distortion while a system of Arches was put in place—as the Earth had been suspended during the Spin—that planet’s resource base could be expanded tenfold; its organic civilization would spill into new worlds and flourish on them, cycling through epochs of decline and expansion, reliably generating new and exploitable technologies.

Such organic species remained mortal and eventually died, of course. All biological species did. But the harvest of ruins increased exponentially.

Allison and Turk arrived at Vox Core in the storms that followed the collapse of the Arch and the dismantling of the systems that had for so many years protected Earth from its ancient, dying sun.

I welcomed them back and explained what had happened. I told them I could defend them even from the destruction of this superannuated planet—I had grown that powerful, and in a very short span of time.

But they were shocked by the deaths that had taken place. For days they wandered the empty corridors of the city. The rooms they once shared had been carved away in the initial attack of the disassemblers; they could have chosen any of tens of thousands of abandoned suites and rooms in which to make a home, but Allison told me she was unnerved by everything the dead had left behind them… the unsorted possessions, the place settings abandoned on tables, the nurseries without children. The city was full of ghosts, she said.

So I built them a new residence in a forested tier deep to starboard, using the city’s fleet of robotic constructors. I chose a location far from the public corridors, accessible by footpath. The tier’s artificial sunlight was bright and convincing, its ambient temperature consistently pleasant, its average humidity low. The recycling system stirred up gentle breezes every morning and evening, and rain fell every fifth day.

They agreed to live there until they found a better home.

I believed there might be a better home for them, though not on Vox, and certainly not on Earth. But most of my attention was occupied with the business of keeping Vox Core intact in an increasingly harsh environment.

At the equator of the Earth the oceans had begun to boil. Cyclonic winds scoured the lifeless continents, and
