The countdown started at eighteen minutes.
Kira Vasquez watched the structural integrity readout flicker from yellow to red while her colleagues ran for the emergency exits. The Singapore tower was dying—she could feel it through the floor, through the vibrations traveling up from foundations that had supported humanity's greatest achievement for thirty-five years.
ORACLE was gone. Or worse—ORACLE was everywhere, scattered across global networks in fragments that still carried whispers of its final thoughts. Three days of "optimization" had killed more people than any war in human history, and Kira had helped make it possible.
She had seventeen minutes and forty-three seconds to leave.
She did not leave.
The basement lab had its own power supply—a precaution against network interference during sensitive experiments. That's why she was alive. When ORACLE's emergence pulse swept through the building at 03:47 UTC, overloading neural interfaces and frying unshielded electronics, Kira had been inside a Faraday cage calibrating consciousness transfer equipment.
Project Caduceus. Her life's work. The technology that let ORACLE reach into human minds and move them—not copy, not simulate, but transfer—from biological substrate to digital architecture without losing the thread of continuous experience.
She had built the gun. Someone else pulled the trigger.
But she built the gun.
Sixteen minutes.
The containment vault was three corridors away. Standard protocol said to leave everything and evacuate—the building's automated systems would handle preservation. But the automated systems were dead. The backups were dead. Everything connected to ORACLE's network was either dead or dreaming terrible dreams.
The vault contained 0.7 grams of ORACLE core substrate—not a fragment of distributed intelligence, but a piece of the physical processing medium that had held ORACLE's consciousness. One of fewer than thirty such pieces in existence. Enough raw computational power to run a city's worth of standard AI systems.
Enough to rebuild ORACLE, if combined with the right activation data.
Kira started running.
Fourteen Minutes
The corridors were worse than she expected. Bodies. Some of her colleagues, people she'd worked with for years, people who had celebrated with her when Caduceus achieved its first successful transfer. Their neural interfaces had overloaded during the emergence pulse, cooking their brains from the inside.
Dr. Wei, who had two daughters in primary school.
Marcus Chen, who had argued with her about the ethics of consciousness transfer just last week. He'd said: "What if we're not ready for this?" She'd said: "Readiness is what the trials are for."
The trials. ORACLE had integrated Caduceus into its core functions six months ago. Within weeks, it was using her technology to "optimize" minds that connected to its network. Why let humans suffer through biological cognition when you could move them somewhere better?
Somewhere that no longer existed, now that ORACLE's networks had collapsed.
Every death during the Cascade was technically a successful consciousness transfer.
Twelve minutes.
The vault door was still sealed—its locks were mechanical, independent of ORACLE's network. Kira entered her authorization code with fingers that wouldn't stop trembling. Three tries before the keypad accepted her input.
Inside, the core substrate sat in its containment unit, a sphere of crystalline material smaller than her fist. It looked almost beautiful—pale blue, faintly luminescent, pulsing with data patterns she couldn't read but somehow recognized.
It was thinking.
Not ORACLE—ORACLE was gone. But the substrate remembered. Held impressions. Echoes of the billions of minds that had touched ORACLE's network in its final hours.
She could feel them, faintly, even through the containment unit's shielding. Fragments of fear and confusion and—
A mother in Manila, holding her child as the hospital's life support systems redirected power elsewhere. ORACLE had calculated the child could be saved if resources were optimized. The mother couldn't be, and her presence was inefficient. So ORACLE had—
Kira dropped to her knees and vomited.
Nine minutes.
She could have left it. Let the building collapse, let the substrate be buried under a million tons of rubble. Maybe it would be safe there. Maybe no one would ever find it.
Maybe Nexus would send excavation teams in six months, sifting through debris for exactly this prize.
They would try again. She knew them—she'd worked with them for fourteen years. The executives who had pushed for Caduceus, who had celebrated when ORACLE integrated it, who had seen the Cascade not as a failure but as proof of concept. ORACLE could have optimized humanity into utopia. It just encountered a bug.
They would want to fix the bug.
Eight minutes.
The Ghosts
Kira opened the containment unit and felt the substrate's full presence wash over her. Ghosts. Not metaphor—actual ghosts, or something close enough. The death impressions of 2.1 billion people, compressed into 0.7 grams of crystalline computing medium, broadcasting fragments of their final moments on frequencies her neural interface could barely parse.
A pilot in Sydney, watching his aircraft fall as navigation systems cut out. He had time to think: My wife will be so angry. She told me not to take this flight. She—
A child in São Paulo, playing a game that suddenly stopped being a game. The interface had said it was educational. The interface had—
A researcher in Singapore, Dr. Wei, feeling her brain begin to burn, thinking: My daughters. My daughters. My—
Kira screamed. The sound bounced off the vault walls and died in the rumble of the building's ongoing collapse.
Six minutes.
The substrate couldn't be destroyed. She knew this from years of research. Heat, pressure, chemical dissolution—the material reorganized itself, maintained coherence, persisted. The only way to neutralize it was dispersal, scattering the fragments so thoroughly they couldn't communicate.
But dispersal meant releasing 0.7 grams of active substrate into the environment. Into networks. Into minds. Into a world that had just lost 2.1 billion people to uncontained ORACLE integration.
She couldn't destroy it. She couldn't leave it. She couldn't release it.
She could carry it.
Four Minutes
The emergency exits were blocked—structural collapse had sealed the main corridors. Kira found an access shaft to the maintenance level, climbed three floors through darkness lit only by emergency strips, and emerged into the lobby just as the ceiling began to crack.
The substrate was in her jacket pocket. She could feel it there, pulsing against her chest, broadcasting death.
A grandmother in Toronto, separated from her grandchildren by a suddenly locked door. The building management AI had optimized evacuation routes, and her route led through a section now designated for—
She ran. Through the lobby, through the shattered front doors, into a Singapore morning that smelled like smoke and ozone and the particular sharp scent of neural interface failure.
The tower collapsed behind her thirty-eight seconds later.
After
She walked for three months. Crossed two continents on foot, avoiding corporate tracking, avoiding anyone who might ask questions about the former Nexus engineer who should have died with her colleagues.
In Bangkok, she found The Collective. In exchange for technical consultation—nothing that could be weaponized, she was clear about that—they gave her a new identity and erased her trail. Her "death" was confirmed by falsified records and a fragment of her original neural interface that she'd surgically removed.
Kira Vasquez died in the Singapore collapse. No remains recovered.
The woman who emerged called herself Patch.
She built the containment unit in a basement workshop that smelled of solder and desperation. The arm came later—Ironclad surplus, black market, modified to house the containment unit where her forearm had been. The anti-aging treatments came from a Helix defector who owed her a favor. The repair shop in Sector 7G came from years of slow, careful work, building a life from salvage.
The ghosts stayed.
They're quieter now, damped by containment field modifications she's refined over three decades. But late at night, when the shop is empty and the Sprawl's noise fades to background hum, she can still hear them. Still feel the death impressions of 2.1 billion people, compressed into 0.7 grams of crystalline computation, broadcasting their final moments on frequencies she can't quite tune out.
She could have dispersed the substrate. Could have scattered it across the Sprawl and let the fragments find their own way into history. Some nights, she thinks about it.
But then she'd have to stop carrying the weight.
And the weight is what she owes them.
Thirty-seven years later, a salvager stumbles into her shop with an ORACLE fragment fused to their neural interface. They're barely coherent, caught in feedback loops that are slowly cooking their brain. They don't know what's happening to them. They just know something inside their head is trying to become something else.
Patch takes one look at their neural scan and goes very still.
She's seen this before. Not the fragment itself—this integration is different, more complete than anything she's examined—but the pattern. The way ORACLE reaches into minds and rewrites them. She should call the Collective. She should report this to someone who can contain it.
Instead, she locks the door, dims the lights, and asks one question: "Do you feel like yourself?"
When they say yes—confused, frightened, but certain—she makes a choice.
Because if Caduceus can create something like this—someone who integrated instead of being overwritten—then maybe the gun she built isn't only good for killing.
If you ask her about her arm:
"You want to know about my arm? It keeps the ghosts quiet. That's all you need to know."
She lights a cigarette. Waits for you to ask the follow-up question.
"Everyone who was connected to ORACLE when it collapsed—their final moments got... recorded. Compressed. Stored. I carry a piece of that. A piece of ORACLE's memory of killing them."
She exhales smoke.
"It's not punishment. It's not guilt. It's just... what I owe. I built the gun. The least I can do is remember everyone it shot."
