Chapter 4: The Thread

Table of Contents

The Mars Deep Space Mining Symposium met once a year at the Ares Orbital Research Station — a gathering of extraction executives, logistics operators, and the particular breed of venture capitalist who had decided that the future of wealth was not on Earth but threaded through the wormholes beyond it. Three hundred attendees, give or take. The presentations ran the usual spectrum: asteroid assay projections, Trunk Line cargo logistics, rare-earth refining techniques for low-gravity environments. The kind of conference where fortunes were discussed in the language of tonnage and trajectory.

Nolan Cade had rented a presentation slot in the afternoon session of the second day — the least prestigious time block, sandwiched between a panel on ice-mining automation and a reception sponsored by a Ceres-based fabrication consortium. He had paid for the slot himself. The title he submitted to the program committee was deliberately bland: Deep-Network Topology and Implications for Long-Range Resource Survey. The kind of title that sounded like it belonged at the symposium. The kind of title that concealed what it actually was.

Forty-three people came. Most of them because the ice-mining panel had run short and the reception hadn’t started yet. A few because they recognized his name — the wormhole discoverer, the man who had been famous for a decade in the particular way that made institutions nervous and individuals curious. And three because Nolan had invited them personally: investors he had identified through months of research the way he had once identified wormhole signatures in archival data — by looking for the compound signal of wealth, appetite for risk, and a tolerance for association with controversial figures.

He stood at the front of a conference room with a curved viewport overlooking Mars. The planet filled the lower third of the glass, enormous and rust-colored, its atmosphere a thin bright line along the terminator. Behind him, the Lacework map glowed on the display — the topology he and Ren had published, every thread converging, the central node pulsing.

He did not begin with the science.

“Every mineral survey in human history,” he said, “has covered the same thin sliver of the galaxy. The Belt. A handful of near-Earth transit systems. The three wormhole destinations we’ve reached so far. In terms of the Milky Way’s total volume, we have surveyed — and I mean surveyed, not observed from a distance — less than one ten-billionth of the galaxy.”

He let that number land. In a room full of people who thought in terms of ore grades and extraction costs, the number did what he needed it to do.

“The Lacework changes that.”

He put the topology map on the display. The room shifted — the particular quality of attention that money pays when it encounters an opportunity it hadn’t calculated.

“The Lacework is a highway. It connects thousands of star systems across thirty thousand light-years, reaching deep into the galactic core — into regions where stellar metallicity increases by orders of magnitude, where the heaviest, rarest elements concentrate in quantities that make the asteroid belt look like a gravel pit. Every wormhole mouth is a door to an uncharted system. Every system is a potential survey site that no human instrument has ever reached.”

He brought up the convergence map. The topology. The gradient.

“Everything in this network points inward. The wormholes grow older and larger toward the galactic center. The systems grow more metal-rich. The infrastructure grows more sophisticated. The path is self-evident — you follow the Trunk Lines inward, hub to hub, and at every stop you survey what’s there. No one has done it because no one has built a ship for the journey.”

He paused. The room was quiet. Mars turned slowly in the viewport behind him.

“I intend to build that ship. And I intend to bring back the most comprehensive deep-space mineral atlas ever compiled.”


He spoke for forty minutes. The presentation was precise, technical where it needed to be, visionary where the numbers left room. He laid out the mission architecture: a purpose-built deep-range exploration vessel, hull geometry reinforced for repeated wormhole transit, redundant navigation for regions where no human pulsar catalogue existed, provisions for two years of independent operation. He presented the cost estimates without flinching — a figure that made several attendees inhale audibly, not because it was impossible but because it was real. This was not a concept. This was engineering.

He did not mention Vasik’s report. He did not mention the UN rejection. He spoke about the science, the destination, and the ship, and he let the audience see what he wanted them to see: a man with a proven track record of finding things that others said did not exist, proposing to find the biggest thing of all.

The questions came. He handled them the way he handled everything — with the patient precision of a man who had thought about every angle long before anyone asked.

Who would crew it? He had a list of candidates. The foremost experts in wormhole topology, exobiology, quantum physics, theoretical cosmology. Names that carried institutional weight even if his didn’t.

What was the return on investment? Data. The complete mineral survey of every star system along the route — ore compositions, asteroid field densities, planetary crust analyses, all at resolutions no remote observatory could achieve. A resource atlas spanning thirty thousand light-years of the inner galaxy, licensed exclusively to mission investors. And — he said this with the careful understatement of a man who knew his audience — the systems closest to the galactic core, where heavy element concentrations were highest, were systems no one else would reach for decades.

What was the timeline? Two years for ship construction at the Ceres yards. Six months for crew assembly and mission planning. Launch in the spring of 2158.

Why him? Because he found the first wormhole. Because he mapped the Lacework’s topology from the outside when the institutions were still cataloguing individual transits. Because no one else was going to do it in time.

He did not say in time for what. The room understood. In time for the people in this room to see the return. In time for the discovery to belong to this generation, not the next. In time for the investors to be part of the story. Nolan understood money the way he understood data: as a system with patterns, and the pattern here was that wealth wanted legacy, and legacy wanted to be first.

After the presentation, two of his three targeted investors approached him separately. The third sent a message before dinner.

By the end of the symposium, he had commitments for sixty percent of the construction budget. The rest came over the following months — a constellation of smaller investors, some drawn by the science, some by the spectacle, some by the particular alchemy of a man who had been right once in a way that changed the world and who was now asking them to bet he would be right again.

Nolan retained design authority over the ship. This was non-negotiable, and he stated it with the quiet immovability of a man who would walk away from the money before he would walk away from the blueprints. The investors accepted it because his expertise was the reason they were writing checks. No one else alive had spent a decade studying wormhole mouths from the outside, modeling transit stresses, analyzing throat geometries. If you were building a ship to thread the Lacework, you wanted the man who had mapped the Lacework to draw the plans.

They did not know — could not have known — what that authority would cost.


The Ceres shipyards occupied a hollowed-out section of the dwarf planet’s crust, pressurized and temperature-controlled, a cathedral of fabrication bays and assembly gantries lit by industrial floods that never dimmed. The Meridian had been built here. So had a dozen survey vessels since. The yards smelled of ozone and hot metal and the particular sharp sweetness of vacuum-rated sealant, and they hummed with the constant low vibration of machinery operating at scales that made human hands feel small.

Nolan arrived at Ceres fourteen months before the projected launch date and did not leave.

He took quarters in the yard’s residential block — a spartan room, smaller than his apartment on Deimos, with no observation port. He did not need one. The thing he wanted to see was being built sixty meters below him, in Assembly Bay Four, and he visited it every day.

The Thread.

He had named the ship himself. A quiet word, easily overlooked, that meant exactly what his life had meant: follow the thread, see where it leads. The Lacework was the fabric. His ship was the strand pulling through it.

The hull took shape over months — a long, elegant geometry that Nolan had stress-modeled in ten thousand simulations, every curve calculated to distribute tidal forces across the maximum structural area during wormhole transit. Not a sphere, not a cylinder, but something between: a form that looked organic, almost biological, as if the ship had grown rather than been built. The shipyard fabricators followed his specifications to the millimeter, and Nolan checked their work with the focus of a man who understood that the difference between survival and death in a wormhole throat was measured in tolerances smaller than a human hair.

He walked the hull during construction the way a sculptor walks a half-finished work — running his hands along the reinforced ribs, checking the joins where structural members met hull plating, feeling for the subtle imperfections that instruments might miss but fingers could find. The fabrication lead, a tall Ceresian woman named Oksana Tereshkova who had built seven ships and was not easily impressed, watched him with the cautious respect she reserved for clients who actually understood what they were paying for.

“The resonance dampeners,” Nolan said one morning, standing in the forward structural bay where four massive dampening arrays were being installed — the systems designed to absorb the harmonic vibrations that wormhole transit generated in the hull. “The spec calls for passive dampening with a response curve tuned to the harmonic profile of the largest known Trunk Line wormholes. I want active dampening on all four arrays. Variable response, tunable in real time.”

Oksana raised an eyebrow. “Active dampening adds weight and complexity. Passive is simpler, more reliable, less to go wrong.”

“Passive is tuned for wormholes we’ve already measured. We’re going to encounter wormholes we haven’t measured. Larger ones. Different harmonic profiles. I want the dampeners to adapt.”

She studied him for a moment — the assessment of an engineer evaluating another engineer’s judgment. Then she nodded. “Active dampening. I’ll revise the installation schedule.”

He was right, and she knew it, and it was this quality — the ability to be right in ways that compelled agreement — that made Nolan Cade both invaluable and dangerous. The same trait that had found the wormhole, that had mapped the Lacework, that had filled a conference room on a Mars orbital station with investors who wrote checks because the data was undeniable. Right. Consistently, specifically, technically right. The kind of right that made people follow him through doors.


The navigation systems went in during month eight. Redundant inertial measurement, pulsar timing arrays, stellar position catalogues for every mapped region of the Milky Way — and, for the unmapped regions, a suite of autonomous positioning algorithms that could bootstrap a local reference frame from raw stellar observations in hours. Nolan reviewed every subsystem personally.

The command architecture went in during month ten.

Nolan reviewed the navigation firmware with Jun Dao, the software integration lead, on the Thread’s unfinished bridge — exposed conduit, raw bulkhead, the smell of fresh sealant. Jun walked through the command hierarchy on a shared display: captain’s console primary, secondary console mirroring it for redundancy. If the captain’s station failed, the secondary assumed control automatically. The failover trigger was hardcoded — loss of signal from the primary console.

“I want the trigger configurable,” Nolan said. “Not at the user level — at the firmware level. A parameter set that can be modified during installation but is locked once the system is committed.”

Jun studied him for a moment. “That adds a potential failure mode. False transfers, or failure to transfer when needed.”

“We’re going to encounter conditions no one has tested for. I want to tune the failover sensitivity to the mission without introducing runtime variability.”

It was a reasonable request. Technically sound. Jun nodded and built it — a configurable trigger layer beneath the standard command hierarchy, accessible only during installation, invisible to the ship’s diagnostic systems. He sent the updated architecture to Nolan for review.

Nolan reviewed it alone, in his quarters, that night. He set the parameters — not the failover sensitivity Jun expected, but something else entirely. A command pathway that allowed the secondary console to assume navigation authority without a hardware fault on the primary. A transfer that could be initiated deliberately, silently, from the secondary station, using a code sequence embedded in the firmware’s deepest layer.

An override.

Not a hack. Not a vulnerability. A designed capability, specified by the mission architect, implemented by the integration lead, buried where no standard diagnostic would find it. Jun had built exactly what Nolan asked for. He had not asked what Nolan intended to do with it, because the request was reasonable.

Nolan committed the firmware. The override was in the ship now, part of its bones, as permanent and as invisible as the convergence gradient in the Lacework’s topology. A door within the door. A thread within the thread.

He did not feel guilt. He did not feel triumph. He felt the cold, settled certainty of a man who had learned — on the Perspicacity, at the UN panel, in Tomoko Sato’s careful voice — that the universe rewarded preparation and punished dependence, and who had decided, with the clarity of a convert, that he would never again arrive at a door he could not open.

Whether he would use it was a question for the future. He carried it the way he had carried the wormhole coordinates on the Perspicacity — quietly, hoping it would not be needed, knowing it might be, and knowing that when the moment came, he would not hesitate.


The Thread was completed in the spring of 2157 — eleven months ahead of the projected launch date, because Oksana’s team was better than the schedule assumed, and because Nolan pushed the timeline with the relentless focus of a man who had spent a decade watching other people leave without him.

He stood in the finished observation bay on the ship’s commissioning day. The bay was small — a concession to structural integrity, since large viewports were weak points in a hull designed for wormhole transit — but it had a single wide port that looked forward along the ship’s axis, out past the reinforced nose, into whatever lay ahead.

The port was dark. Ceres was behind them. The bay was lit only by the soft amber of standby lighting, and in the glass Nolan could see his own reflection — fifty-nine years old, leaner than he’d been in Wyoming, the lines deeper, the patience harder. Behind the reflection, stars.

No folding chair in this bay. No thermos. He had left those on Deimos, in the apartment he would not return to, beside the observation port where he had spent seven years watching ships leave without him.

He was done watching.
