The Dark Forest Protocol

The woman came to my office on a Tuesday, which was already suspicious. People in New Carthage didn't visit detectives on weekdays. Weekdays were for the living. The dead—or the naked—came at night, when the holographic billboards dimmed and the rain stopped long enough for someone to move without drawing attention.

Her name was Elena Voss. Her husband had disappeared three days ago. Not physically—he was still in their apartment on Level 42—but his coordinate was gone. His profile had been wiped clean. The system showed him as a blank entry, a person with no social graph, no resource allocation, no medical record. He existed, but the city didn't.

"Can you find him?" she asked, sitting across from my desk with hands that wouldn't stop moving. She was young—maybe thirty—and her eyes were the kind of grey that belongs to someone who has seen things the colour spectrum can't describe.

"I can look," I said. "But if his coordinate's been nulled, he's already past the point of no return. Once the system forgets you, nothing in this city can find you."

She slid a credit chip across the desk. Untraceable. Enough to make me curious and not enough to make me careless. "They called it the Dark Forest," she said. "That's what he told me it was called. Before he disappeared."

I didn't ask for more details. In New Carthage, the more you know, the sooner you start disappearing too.

Act II

The dark market for coordinates operated out of the lower levels of the city—below the Corporate Council's jurisdiction, above the toxic runoff channels where the atmosphere processors dumped their waste. The traders called themselves "Shadow Graphers," and they dealt in something more valuable than drugs, weapons, or information: anonymity.

I met my first Shadow Grapher in a bar that existed on no city map, in a building that had been condemned thirty years ago and forgotten by everyone except those who needed to be forgotten. His name was Kade, and he had more synthetic components than human tissue. His left arm was all carbon-fibre and servos; his eyes were camera lenses; his voice was a synthesized approximation of something that had once been human.

"You want to know who's nulling coordinates?" Kade said, swirling synthetic gin in a glass that hadn't been washed. "It's not the Council. The Council doesn't care. Naked people are free labor if you can find them, and they're free real estate when they starve. No, this is something else. Something older."

"Older than what?"

"Older than the city. Older than the Council. Older than the concept of a coordinate. They call themselves the Protocol. And they're not nulling coordinates for money. They're collecting them."

I spent the next three weeks tracking leads through the criminal underbelly of New Carthage. Every naked person I found had been connected to the Protocol in some way. Some had bought coordinates illegally. Some had sold theirs voluntarily. Some had been targeted without warning. But every single one of them had followed the same pattern: first, their social connections were severed. Then their resource allocation was cut. Then their medical files were erased. Then their face—people stopped recognizing them. Then the system itself forgot them.

It was a systematic unmaking. And it was happening at an accelerating rate.

Inspector Yara Okafor met me at the edge of the condemned district, where the city's walls dissolved into the rusted remains of the old atmospheric processors. She was a pure human—no synthetics, no modifications—and she despised me for having more metal than flesh. But she respected results, and I was the only detective who could solve cases the system couldn't track.

"You're close," she said. "Too close. I can feel the Council watching. They don't know what you've found, but they know you've found something."

"I'm looking for a service called the Dark Forest Protocol," I said. "I want to know who runs it, who uses it, and why people are disappearing."

Yara's face went pale. Not the pale of fear. The pale of someone who had heard a word they didn't want to hear and was trying not to react to it. "Moretti," she said quietly, "you need to stop."

"I can't. The pattern's almost complete. I just need to find the source."

Act III

The source was in a derelict atmospheric processor on the city's eastern edge, a tower of rusted metal that had been abandoned when the Corporate Council found more efficient ways to process the atmosphere. Inside, I found servers—thousands of them, arranged in rows that stretched as far as the darkness allowed me to see, each one humming with the low, constant vibration of data being stored and processed.

And I found the truth.

The Dark Forest Protocol was not a criminal organization. It was a survival mechanism.

The naked people weren't being killed. They were being protected. Their coordinates were being extracted from the city's system and transmitted into deep space, where a service called "The Singer" was collecting them. The Protocol wasn't erasing people—it was hiding them from something.

I found this out when I accessed the Protocol's master database. The files were encrypted, but my synthetic nervous system had access to frequencies and decoding methods that Yara's pure human brain couldn't replicate. What I found inside made my blood run cold.

The Singer wasn't a person. It was a signal. A pattern of electromagnetic radiation being broadcast from somewhere beyond the colony, from the deep space between stars. The signal had specific properties—it targeted naked coordinates and routed them toward a destination that I couldn't identify. But the signal was old. Incredibly old. It had been broadcasting for longer than the colony existed, longer than New Carthage had been built on this moon.

And it was growing stronger.

The Corporate Council knew. They had known for decades. They allowed the Protocol to operate because naked people were useful to them—people without coordinates couldn't unionize, couldn't demand better conditions, couldn't resist exploitation. But the Council was also afraid. The Singer's signal was growing stronger, and they couldn't control it. They couldn't stop it. They could only watch as more and more people lost their coordinates and disappeared into the void.

I confronted the Singing Contractor that night, in the deepest level of the server farm, where the hum of a thousand machines became a physical pressure against my skull. The Contractor had no physical form—only a voice, synthesized and encrypted, coming from everywhere and nowhere.

"Why?" I asked. "Why are you doing this?"

The voice answered: "We are not doing anything, Detective. We are receiving. The Singer is not us. We are the ones who listen. We are the ones who remember the ones who were taken."

"Taken by what?"

"A law of the universe. A principle as old as consciousness itself: in a universe where every intelligence is a potential threat, the only way to survive is to be invisible. But invisibility has a cost. To be truly invisible is to cease existing in the world of the visible. The Singer collects the invisible. We listen to what they say after they're gone."

Act IV

I had a choice. I could expose the Protocol to the Corporate Council, which would destroy it and send the naked people back into a world that would consume them. Or I could let the Protocol continue, knowing that every person it "collected" was being erased from existence and sent somewhere I couldn't understand, by something I couldn't control.

I chose neither. I did what any good detective does: I investigated my own coordinate.

It took me six hours to access my own social profile, and the results made my synthetic heart stop—if synthetic hearts stopped. My coordinate showed minor deviations. Not enough to trigger an alarm, not enough to make the Council notice. But enough to make the Singer notice.

I was already being watched.

The message came the next morning. Not from the Contractor. Not from the Singer. From my own coordinate, sent from outside the system. A single line of text, appearing on my terminal at exactly seven in the morning:

Jack Moretti. I know who you are. I know what you've found. Come to the edge of the colony. The Singer has a message for you.

I stood on the launch platform of the deep-space station at the colony's edge, looking out at the stars. The message had not specified a time. It didn't need to. The Singer was patient. The Singer had been waiting longer than humanity had existed, and it could wait a little longer.

I thought about Elena Voss and her disappeared husband. I thought about the naked people wandering the lower levels of the city, invisible to everyone except me. I thought about the Singing Contractor and the signal that had been broadcasting for longer than the colony existed.

And then I made my decision. I picked up the comm unit and said the only thing I could say: "I'm coming."

The stars stared back. They didn't answer. But somewhere, in the space between them, something was listening.
