Three hundred meters down, in the drowned grid of old Jakarta they call the Quiet, there's a traffic light that still changes. Red to amber to green, every forty-seven seconds, for nobody, in water dark enough to drink. The first time I saw it I laughed so hard I nearly lost my air, and at three hundred meters laughing yourself out of air is just a slow way of laughing yourself to death.
I keep going back to look at it. That's a confession. There's a fortune on this dive and a death sentence in my own blood and the thing that pulls me down the shaft every time is a dead machine doing its small dumb job in the dark, patient, faithful, switching a color no eye will ever read. Nobody wired it. Nobody feeds it. It runs on something that comes up through the drowned street from the deposit, and it has run, by the Shelf's reckoning, since before the water came, obeying an instruction nobody remembers giving, controlling a flow of traffic that drowned forty years ago. You want to understand the Scatter, start with that light. Everybody down here is still changing for nobody.
I'm a Red Siren. That's the polite catalog name for what they made me, aquatic-adapted gene-forged, eleven-minute breath-hold, eyes that open up in murky water like a second dawn, a body tuned to work cold and deep where the baseline crews drown trying. The catalog leaves out the rejection rate. The catalog always leaves out the rejection rate. They build you a body that can reach the things nobody else can reach, and they build it on a clock, and the clock has a name, and the name is Drift, and I'm in Stage 3 of it, which I am not supposed to be telling you or anyone, because Stage 4 is mandatory containment, and containment is the polite catalog name for the place the Scatter sends the gene-forged who've started to come apart so the rest of you don't have to watch. My hands shake at the surface now. They go still the second I'm under, which is the cruelest joke the build ever played on me. The only place my body still works right is the one place that's killing it faster.
Which is why I took the job, and the job was a Lumicite sample.
Ibu Naga handed it to me on the Shelf, up in the rooftop sprawl where fourteen thousand people the Pacific Free Zone refuses to admit exist live on the drowned grid and tap power off something they don't ask too many questions about. Ibu Naga isn't a name, it's a title, the Dragon Mother, and the current one runs the southern Scatter's black market out of a shipping container that smells of fish sauce and ozone.
"One sample," she said. "Off the Arafura deposit. Before the Free Zone locks it down and the only people who get to touch the future are the ones who already own everything else." She watched me with the flat patience of someone pricing a thing she already knows the price of. "It'll buy you a deck above the flood line. It'll buy a clinic that treats what you've got. Don't make the face. I've buried four of your model. I know the walk."
"Dian Kartika took this job."
"Dian Kartika took this job," she agreed, and didn't say the rest, because the rest was that Dian went down to Arafura ten days ago and came up with something that wasn't a Lumicite sample, went back down to put it back, and never surfaced. The Shelf doesn't say drowned. The Shelf says the water kept her. Same thing, kinder grammar.
Here's the Scatter, so the rest makes sense. When the sea came up faster than the models promised, it didn't make a wasteland, it made a puzzle, a scatter of new islands and drowned cities and the water between them, and whoever controls the water between things controls everything, and that's the Free Zone, squeezed between a Pacific Rim Collective that needs the seabed cables running north for reasons it won't discuss and a Northern Alliance base to the south that exists to be a problem. Three of the six Makassar cable nodes are failing, corroding faster than coral and current can explain, and if they go, a third of the world's data routing goes dark with them, and everybody who runs the water between things knows it and nobody can say why it's happening, and into the middle of that, the Free Zone decides the move is to lock down the one Lumicite deposit on the seabed that everybody suddenly, desperately wants a piece of. Demand showed up like weather. No announcement. Just, all at once, every faction on the water deciding the deposit was the thing they could not afford to let another faction have.
The descent is the first dive that matters and I'll give it to you the way it happens, fast and dark.
You go down past the Shinkai Collective's habitat at two-eighty, modules three years past their rated life, lights on inside where Dr. Keiko Watanabe and her people study a thing they're trying very hard to study responsibly while the whole rest of the ocean tries to grab it, and you go past them into the Quiet, and the deposit is there, and the deposit pulses. That's the part the surveys file as a sensor artifact. It pulses, slow, a light in the rock with a rhythm, and the drowned traffic light forty meters off pulses with it, in time, the same forty-seven seconds, the machine and the mineral keeping the same heartbeat across a dead intersection. A metallic contact held station ten meters off my shoulder the whole time, patient, attentive, not hostile, the thing the sonar's logged in the shadow zone for three years and nobody will name, and I worked under its attention the way you work under a parent's, and I found Dian's lines first. Cut. Fresh. A rival diver had been here and gone, or been here and stayed, and I didn't have the air to find out which.
I cut the sample. That's the job. One node of Lumicite off the face of the deposit, and the instant it came free in my hands the deposit's pulse stuttered, skipped, sped, and forty meters away the dead traffic light skipped with it, and I felt the rock around me complain in a register below sound, and I understood, with the sample bleeding cold light into my glove, that I had just done something much larger than steal a rich rock.
The run out was the second dive and it's where the body and the truth ran out together.
I came up through the cable-node field with the sample in a FLOATPACK against my chest, and the field was crowded, because everyone had moved at once. A Free Zone Corsair patrol working the nodes. A Pacific Rim platform sitting over the Makassar crossing under commercial cover, its drones in the water. Five kilometers of bright surface above with two fleets holding their breath across it, and down in the dark me, one Drifting diver with a stolen heartbeat in a buoyancy pack, threading between them. And the body picked that moment to file its report. The breath-hold went short. The vision grayed at the edges, that soft gray that comes up from the sides, and I could not tell, I genuinely could not tell, whether it was the depth taking my air or the Drift taking my eyes, the two clocks I live between finally syncing up to ring at once, and there is a particular terror in not knowing which thing is killing you, because you can fight the depth, you can fight the depth your whole engineered life, but you cannot hold your breath against your own genome. My hands started to shake. Three hundred meters down, in the one place they're supposed to stay still, my hands started to shake, and that's how I knew Stage 4 had sent a scout ahead to look at me.
I made the surface. I always tell myself I'll make the surface and one day I won't and the sentence will just stop mid
I made the surface.
And here's what the sample turned out to be, which Watanabe confirmed later in a voice gone thin with the horror of having helped, gently, responsibly, for years: it's not a rock. It's a node. The Arafura deposit is one end of a pre-Upheaval geological conduit, a thing the old world built or found and the new world drowned and forgot, and every node you cut off the face makes the deposit pulse to rebalance, and the pulse runs the conduit two hundred kilometers north and surges up under the Shelf, and the surge is what's been corroding the cable nodes, accelerating them, eating the wire that holds the world's data together. The treasure everyone is killing to own is the load-bearing nerve of the thing that's about to put two fleets in the water and a third of the planet in the dark. And nobody built that. That's the part I can't get out of my teeth. There's no mastermind. There's just demand, every faction wanting the rock for its own reasonable reasons, and a thing out in the shadow zone called CURRENT that didn't make the disaster, only noticed that two systems would collide if somebody started cutting samples, and made sure somebody did. The Scatter is assembling its own ending out of a thousand reasonable purchases, and the traffic light keeps changing for nobody, and we are all of us still changing for nobody, on time, in the dark.
So the arithmetic, done at the surface with my hands shaking and a fleet on each horizon.
Surface the sample and get paid, buy the deck and the clinic, buy myself out of Stage 4, and feed the exact demand that's cutting the nerve that drowns the Scatter. Leave it, stay broke, stay Drifting, ride the build down into containment where they put the ones like me who've started to come apart. Or surface the truth instead of the sample, hand Watanabe's people the proof that the deposit's a conduit and not a treasure, and watch every faction on the water hear the word conduit and decide they have to be the one who owns it, and carve the thing open faster than CURRENT ever could. Every version that saves the Scatter costs me the clinic that saves me. The body they built to reach the truth is the body the truth runs out of. I cut the sample with hands that only work underwater, and the truth I cut loose is the one thing I can't hold my breath against.
I'm not going to tell you which I carried up. I'll tell you I went back down once more, after, to the Quiet, against every reasonable instinct, to look at the light. Red to amber to green, forty-seven seconds, for nobody, faithful as ever, keeping time with a wound in the rock that's going to take the wire down and the fleets with it. The metallic contact was there, holding station, attentive, the way it's been attentive for three years, watching us cut the nerve of the world a sample at a time and pay each other for the privilege.
My hands were still, down there. The way they only ever are down there. I held the FLOATPACK and I watched the light change and I decided what I was, which is the only decision the dive ever really offered, and then I went up into the loud bright surface where the body fails and the fleets wait, and I changed, on time, for nobody, like everything else down here that the old world wound up and forgot to stop.
