6. What the Dead Colonies Wrote

Decoding a language was not something you did in a day. Kira knew this from experience — her graduate thesis had involved partial reconstruction of a degraded transmission protocol from one of the early deep-field relays, and that had taken her four months and a small breakdown in the third week of November. This was going to be harder. Declan had a workspace on Level 11 of the residential ring: two rooms that he rented through a chain of anonymous sub-leases that would take considerable effort to trace. The second room was the one they worked in. It was small, over-ventilated, and contained the dense layered clutter of someone who had been doing careful research in a confined space for a long time. Physical notebooks stacked in columns. Printed spectrographic analyses pinned to the wall. A cluster of processors that had been assembled, Kira suspected, from components that would not show up on any authorized tech registry. "You built all of this yourself?" she asked, on the first morning, surveying the hardware. "Over three years, yes." Declan handed her a mug of coffee and sat down at the main terminal. "I couldn't use any system that could be monitored. Which ruled out essentially everything commercially available." Kira pulled out her data drives and got to work. The raw waveform data ran to approximately fourteen hours of recorded transmission. It had been cleaned and filtered during her initial capture — she had been thorough, even in those first disorienting minutes when she hadn't yet understood what she was looking at — and what remained was as clear as deep-space transmissions got: a remarkably strong signal, surprisingly free of the distortion and dispersion she would normally expect at that range. That alone was information. Whoever was broadcasting had access to equipment that shouldn't have existed on a two-centuries-isolated colony. She flagged it, noted it, and kept going. The signal was composed of layered frequency patterns. On the surface level, it read as a simple repeating pulse — the forty-two-second interval she'd clocked. But when she ran the waveform through a spectrographic decompiler and began examining the sub-frequencies, a second structure emerged: a dense, modulated pattern riding beneath the primary pulse like a message tucked inside an envelope. "It's a carrier wave," she said. "The forty-two second pulse is just the outer wrapper. The real content is here." She pointed to the secondary layer on the display. "Encoded in the modulation." Declan leaned in, studying the screen. "Can you isolate it?" "Already doing it." What emerged, after three hours of separation and cleanup, was a sequence of data blocks: dense, structured, and entirely unlike any encoding standard in Kira's database. The blocks were not random — there was clear internal logic to them, repeating structural elements that suggested grammar, organized units that suggested vocabulary. It was a language. Whether it had evolved from one of Earth's languages or developed entirely independently on Kepler-7d was impossible to say without much deeper analysis, but the architecture was unmistakably linguistic. Avery, who had been quietly eating crackers and watching from the corner, put down his crackers. "It's actually a language," he said. "An actual language." "Yes," Kira said, not looking up. "Written by people who have been living twelve hundred light-years away for two hundred years." "Also yes." "And we're trying to read it." "That is precisely what we're trying to do." He was quiet for a moment. "Okay," he said, and picked up his crackers again. The decoding process took four days, working in shifts, running the data through every pattern-matching framework Declan's custom processors could run. On the second day they found the structural pivot — a set of recurring elements that functioned as grammatical markers, separating subjects from predicates, clauses from statements. On the third day Kira identified a subset of vocabulary items that showed clear derivation from English roots, heavily modified by two centuries of linguistic drift but still traceable: words for sky, light, depth, silence, memory, danger. On the fourth day, she decoded the opening statement of the message. She had been working since before dawn, running on coffee and the kind of focused intensity that made the rest of the world go flat. She almost didn't realize she'd done it — almost read past the first clean translation before her brain caught the meaning and everything stopped. She said: "Come in here." Her voice came out very quiet. Avery and Declan were both there within a minute. She pointed at the screen. The translation was imperfect, still rough in several places, but the core of it was clear. The opening statement of the Kepler-7d transmission read: We are the children of those who chose silence. We have carried the knowledge beneath the stone for seven generations. The thing they found is still here. It is waking. Do not come in force. Come with understanding, or do not come at all. The three of them stood in the small, over-ventilated room and read it three times. Then Declan said, very quietly: "The thing they found." "It's waking," Avery said. Kira stared at the words on the screen. In her chest, the electric conviction that had lit up at 4:17 a.m. in the monitoring bay was burning with a clarity that almost hurt. "We need to send a reply," she said. "We can't send a reply from here," Declan said. "We'd need a deep-field array. The Bureau controls every array in the system." "Not every one," Avery said. Both Kira and Declan looked at him. He was looking at the floor with the expression of a man doing math he didn't particularly want to do. "There's an old relay station. Decommissioned. Out past Titan. I've hauled salvage through that sector." "Would it still function?" Kira asked. "I don't know," he said. "But I know where it is." He looked up. "And I know nobody's monitoring it." Kira looked back at the screen. At the words. Come with understanding, or do not come at all. "Then that's where we go," she said. Behind them, somewhere in the wall, the air recycler hummed its steady rhythm. Outside, Ganymede went about its business, oblivious. And on a planet 1,200 light-years away, a signal kept repeating, patient as a heartbeat, waiting for an answer.
