Dead Reckoning

by Charlie Forêt

A short story set approximately 14 years after the events of Signal Zero.

The Null Margin was what you got when someone who loved you handed you both their best asset and their worst debt simultaneously, and then had the poor timing to die before you could argue about it.

Fourteen years after my mother first flew her through a Flux-scoured trade corridor on the edge of what most people called the Fringe and most other people called "the reasonable boundary of human habitation," the ship was still running. Barely, and with the mechanical personality of a grudge, but running. The Integration overlay had been active for about as long. Though my mother had been five years into her relationship with the system when she died, I had been significantly less committal about the whole thing.

The overlay was present. I'd acknowledged that much. It floated in the upper-right quadrant of my vision like an uninvited houseguest who had decided the question of their residency was settled and I was simply going to have to adapt. The numbers there were the same numbers that had been there last month and the month before: Integration Level 7, Designation SCOUT, and a set of attributes I'd learned not to look at too closely on the grounds that looking at them too closely felt like reading your own autopsy.

My mother had found the system meaningful. She'd invested her stat points with intention, studied the designation trees, asked the other Fringe captains about skill drops and Rift schedules. "It's a tool," she'd told me, the last time we'd disagreed about it. "You don't stop using a navigation computer just because you don't understand how it works."

She'd been right, probably. But she'd also been running cargo through the Kaspar Corridor when the Unintegrated came through it, and neither the Integration nor any of her carefully allocated attribute points had changed how that ended.

So. Not a tool I was in the habit of picking up.

The problem with the Fringe, as a category of space, was that the Integration's influence thinned at its edges the way a signal did, functional in the center, increasingly unreliable toward the periphery, and at the actual boundary, capable of delivering readings that were technically data and practically useless. Holdfast Station sat in what system analysts charitably described as a "variable-density Integration zone" and what every ship captain who regularly docked there described using language that wouldn't survive transcription.

I'd been docked four hours when the Flux Storm rolled in.

Category 2, the overlay said. Then it revised to Category 3 before I'd finished reading the initial alert, which was the sort of immediate recategorization that made a person trust prediction algorithms very little going forward.

The timing was not ideal. An hour earlier I'd taken on a passenger. Brem, a twenty-four-year-old engineer from the Steady Margin (not my ship; different Margin; the name coincidence was either a good sign or a terrible one, and I'd been unable to decide which), whose captain had experienced a medical emergency mid-run and been carried off to Holdfast's medical bay. Brem had been standing on the dock with the expression of someone whose entire professional situation had just become significantly non-standard, and I'd done the thing I always regretted: offered a berth. He was quiet, which I appreciated. He was competent with tools, which I discovered when he asked if he could do something useful. I handed him three faults from the Null Margin's maintenance queue without expecting much. He cleared all three in forty minutes.

The Flux Storm did not care about any of this.

What a Category 3 Flux Storm did to navigation systems was the same thing it did to most precision instruments: it introduced an uncertainty principle with teeth. My overlay flickered. Brem's eyes went slightly unfocused in the way that happened when a person's overlay was throwing static. The Null Margin's navigation suite, which ran on conventional tech with a system-assisted layer bolted on top, started producing readings that disagreed with themselves in interesting ways.

I looked at the readings. I looked at Brem.

"How are you with pressure suits?" I said.

The Null Margin's external navigation array was a hybrid unit, and the hybrid nature meant that when the Flux disruption hit the system-assisted layer, it created a feedback loop that was slowly corrupting the conventional layer's baseline calibration. This was a fixable problem if you went outside and physically reset the calibration node, which was located on the ship's underside in the spot the designer had clearly chosen by picking the worst possible option from a list.

"You should not do this," Brem said, with the tone of someone who had assessed the situation and arrived at a professionally responsible conclusion he fully expected to have ignored.

"I know," I said.

"The external atmosphere is Category 3 Flux-active. Your stats—"

"I know."

He looked at the overlay in his own visual field, running numbers I couldn't see. "The storm is already producing localized distortions. Depending on your Flux, that's going to feel like—"

"Brem." I sealed my helmet. "If I don't reset that node, we can't navigate when this storm passes. If we can't navigate when it passes, we're sitting at Holdfast with no outbound routing until they get a specialist out here, which will be three weeks because we're in a variable-density zone that no specialist wants to visit. I have a cargo contract with a hard deadline. So."

He was quiet for a moment.

"I'll be your eyes," he said. "On the secondary system. I can track you on the conventional cameras."

"That's useful," I said, and meant it, which was not something I said to people very often.

Outside was worse than the instruments had suggested, which had been worse than I'd expected, which had been bad. The Flux Storm's effect on a high-Flux individual was reportedly manageable, even exhilarating: abilities becoming more powerful and erratic, the system's wild edge feeling like a tailwind. I was not a high-Flux individual. I was a Fringe navigator with a 9, solidly mid-range for human standards, which meant the storm felt like trying to move through air that had developed opinions about your direction of travel.

My overlay threw errors. It corrected them. It threw different errors. The stat numbers in the upper right flickered and stabilized and flickered again. Drive losing a point and recovering, Signal spiking briefly and settling, the whole display developing the visual quality of a transmission losing its signal.

Appropriate, given the situation.

"Still with me?" Brem's voice in my helmet.

"Still here." I'd reached the ship's underside. The calibration node was exactly where the schematics said it was, which was the one thing going right. "I can see the unit. Housing's intact."

"The storm is building. My overlay says Category 3 stable but I don't trust these readings."

"Don't trust them," I agreed.

I hooked my safety line through the designated anchor point. The Null Margin had these; my mother had drilled their locations into me before I was old enough to think they'd matter. I started working on the housing latch.

The latch had corroded. Of course it had. I'd been budgeting for the latch issue for two quarters and hadn't gotten there yet, because the budget situation was what the budget situation was.

I had a pry bar. I'd brought the pry bar specifically because the latch situation was a known quantity, which was the kind of operational foresight that deserved more recognition than it received.

I pried.

Above me, or below me, since the geometry of orientation had gotten complicated, the Null Margin's hull gleamed in the pale functional light of the station docking ring, and beyond it, the Flux Storm's visible component drifted through the region like weather that had stopped believing in physics. The colors in the far distance were wrong. Not dangerously wrong, not yet, but the kind of wrong that reminded you the Integration's rules were suggestions out here, not laws.

"Senna." Brem's voice had changed. Very even. Very careful. "The storm is shifting. The conventional sensors are… I'm getting a new reading."

"How long do I have?"

A pause. "Twelve minutes. Maybe less."

I had the latch open. The calibration node was accessible.

I want to be honest about the next seven minutes because I think honesty is what they deserve: they were not graceful. I have good hands. Twenty-three years of maintaining a ship with insufficient budget will do that. I knew the reset sequence without checking the manual. But I was working in worsening Flux conditions with an overlay that kept throwing spurious warnings and a safety line that had, at some point, developed a personality and decided to express it through resistance.

I did the reset.

I confirmed the reset.

I confirmed the confirmation.

I started back toward the airlock.

"Senna." His voice was different now. Careful in a way I recognized.

"I see it," I said.

The storm had shifted to Category 4.

I won't write the airlock sequence at length. It was fast, and it was close, and there is a very specific kind of focused calm that descends when you've decided that fear is a luxury you can't afford right now and you'll be afraid later instead. I'd learned that particular calm from my mother, who had learned it the same way everyone learns it, by being in situations where the alternative was not surviving them.

Brem had the inner door open before the pressure equalized. He was standing there with the expression of someone who had just watched something nearly go wrong and was still processing whether it was actually over.

"Navigation's up," he said.

"Good." I pulled the helmet off. "That's good."

I was sitting on the airlock floor. I wasn't certain when I'd decided to sit, but it seemed like a reasonable choice, so I stayed there for a moment.

The storm beat against the hull above us: the low structural percussion of a Category 4 passing through, felt in the bones rather than heard, the Null Margin's frame absorbing it the way it absorbed everything, not gracefully, but completely.

And then the system spoke.

[Threshold reached.]

[Scout criteria met. Navigation integrity maintained under extreme Flux disruption. Fringe corridor transit secured.]

[Integration Level advancing. Seven to eight.]

[Three attribute points available. Allocate when ready.]

[Scout Designation Rank advancing. Unranked to Proven.]

[New overlay functions accessible.]

I looked at the notifications. The numbers were real. IL 8 sitting there where 7 had been, solid and new and absolutely unasked for. My first reaction was the same complicated thing I'd had every time the system acknowledged me for anything: an involuntary flash of satisfaction followed immediately by the instinct to argue with it.

It had been measuring me. While I was out there with a corroded latch and a static-filled overlay and a storm that kept changing its mind about how dangerous it wanted to be, the system had been watching. Tallying. Rendering judgment. The system was always doing that, with its alien patience and its alien categories, and most of the time I managed to ignore it.

Right now, sitting on the floor of my own airlock, that was harder.

[New overlay functions accessible.]

I hadn't noticed that line at first. I noticed it now.

I'd never looked at the overlay's feature set closely enough to know what was standard and what unlocked over time. The overlay had arrived the way it arrived for everyone, there one day, comprehensive and uninvited, and I'd spent most of the fourteen years since treating it the way you treated a persistent noise: present, noted, incorporated into the background of experience without ever being engaged.

The new functions were listed in a sub-menu I'd never opened.

Minimize Overlay, said the first option. Reduce display to peripheral indicator. Full interface accessible on demand.

I looked at it for a moment.

I selected it.

The overlay contracted. The stat numbers, the IL indicator, the Scout designation marker that had occupied my field of vision since it arrived. All of it folded down. It didn't disappear. It became a small, unobtrusive indicator at the very edge of my peripheral vision, somewhere I'd never look unless I meant to.

The center of my visual field was just the airlock. Just Brem, crouched a meter away with his arms on his knees, watching me with patient attention.

I hadn't known you could do that. All these years, and I hadn't known. Not very observant for a Scout.

I stayed with the empty center for a moment. Just the floor, and the wall, and the sound of the storm outside tapering down, and a person who had been a stranger three hours ago.

The second new function said: Share Profile. Transmit current Integration Profile to consenting recipient.

"What does yours look like?" Brem asked.

I glanced up. He was watching me with the focused attention of someone who'd been through something and had come out the other side of politeness.

"What?"

"Your screen. Your stats." He had the directness of people who've stopped performing normal. "You went up a level. You went still after you got your helmet off. Nobody holds that still unless their overlay is doing something significant." He paused. "I've been wondering what someone who does what you just did looks like in the system."

I'd been wondering the same thing. That was the uncomfortable part.

I looked at the share function.

The thing about the system was that it had an answer for everything, or it thought it did. The numbers in an Integration Profile were the system's complete statement about a person: what they were, reduced to six attributes and a designation and a level and a rank. Fourteen years of watching. This was the compilation.

I'd never shown it to anyone.

I selected Share Profile. The request went to Brem's overlay. I watched his eyes change. The brief focusing-and-unfocusing that meant interacting with an overlay notification. He accepted.

His eyes moved across the text only he could see, and then stilled.

I knew what he was reading.

Signal: 11. Frame: 8. Drive: 13. Lattice: 7. Echo: 5. Flux: 9. Scout, Level 8, Designation Rank: Proven.

Drive 13. The system had decided that whatever kept me going when everything else said stop was the most significant thing about me. I'd never quite known what to do with that assessment. My mother had told me she had a Drive of 14. Then she died. I had wondered, more than once, if that was what killed her, the inability to stop when stopping was the safe option.

"Echo five," Brem said, and he didn't make it a question.

"I don't engage with it much."

He nodded. He didn't push. "Flux nine. That's… that's low, for what you just did out there."

"It's not the stats that made it work," I said, and then stopped, because I hadn't meant to say that out loud.

"No," he agreed. "It wasn't."

The Null Margin's hull creaked, thermal settling as the storm moved through its loudest phase outside. The small indicator at the edge of my vision noted the shift:

[Flux Storm condition downgrading. Category three. Stabilizing.]

Safe to navigate again. Mission parameters met.

I was sitting on the floor of my airlock, sharing my stat screen with a stranger who had talked me through a Category 4 Flux Storm from the other side of an airlock door, and the system was pleased with me for the first time in years, and I was trying to understand why that felt like the least significant thing that had happened in the last ninety minutes.

"You can dismiss it," I said. "The profile."

"I know," he said. He didn't.

We navigated out of the Holdfast approach corridor three hours later, the Flux Storm dissipating behind us, the Null Margin's navigation array running clean for the first time in a month. Brem had taken the co-pilot's berth without being invited and then done nothing that made me want to rescind the arrangement. He was reading something on a handheld. He had the quality of people who are comfortable with silence, which was the most important quality a person could have if they were going to be on my ship.

I had the overlay minimized. I'd left it that way since the airlock. The small indicator at the edge of my vision was there if I looked for it, and not there if I didn't.

Fourteen years. I'd been carrying the full display in the center of my field of vision because I hadn't known I could set it down. That seemed like a thing worth knowing about yourself, that you'd been carrying something and not knowing you could put it away. Not throw it out. Just tuck it somewhere you chose, on terms you set, accessible when you wanted it and quiet when you didn't.

The system hadn't told me I could. It hadn't told me I couldn't. It had waited until I actually looked at what it was offering, which was either patience or indifference, and I wasn't certain which interpretation was more unsettling.

[Attribute allocation pending. Three points available. Designate allocation when ready.]

I looked at the prompt.

Drive was already 13. That was the system's verdict on what powered me, and I'd made a kind of grudging peace with it being right, even while resisting what it implied. Signal 11 made sense. I noticed things; I always had; it was how you survived on the Fringe before you had the vocabulary to call it a stat. The rest of the numbers were what they were. Frame, Lattice, Flux, all human-baseline for a Fringe navigator with years on her. Nothing that surprised me, nothing that stung.

Echo 5.

I thought about the share function. The particular exposure of it, here are the numbers, here is the system's case for what I am. I'd kept the Integration at arm's length for years partly because engaging with it meant trusting it, and trust was a resource I'd learned to budget. But I'd shown Brem anyway, and nothing had collapsed. He'd read my Echo score and not told me what it meant that I'd kept the system at distance. He'd just noted it. Sat with it. Let it be what it was.

Maybe that was the thing about showing someone your numbers. The system reduced you to six attributes and a designation. It was correct, as far as it went, and it went a certain distance, and the distance was not all the way. Showing the screen to someone took trust.

Sharing with someone who had watched you work, and was still reading your Echo 5 with equanimity rather than judgment, that changed what the numbers meant. Not what they were. What they meant.

I put one point in Echo.

[Echo updated. Five to six.]

It wasn't forgiveness. It wasn't trust. It was one point, which was the smallest move the system allowed, which seemed about right.

We were doing dead reckoning out here, no established lanes or orbits, no guaranteed guidance, just accumulated knowledge of where we'd come from and a chosen direction forward. That had always been how the Fringe worked. That had always been how I worked.

It had called me Scout.

It had been watching a long time.

I wasn't ready to say it was wrong.
