Back in her workstation-a corner of the ship that doubled as lab, library, and personal chaos archive-Dr. Lira pulled up every data point she'd collected on the sector's spatial anomalies.

  Tavi's signal was just one piece. There were others: navigation drift reports from cargo haulers, sensor ghosts logged by survey crews, derelicts that appeared on charts and then vanished or moved. Small inconsistencies, easy to dismiss individually.

  Collectively, they formed a pattern.

  She plotted them on a three-dimensional map. The signal source sat near the center of a loose cluster-not exactly a geometric arrangement, but not random either. More like stones thrown in water, ripples overlapping.

  Those mathematical ratios appeared in three separate transmissions across the cluster. Same sequences. Different sources, different encoding formats, but structurally identical.

  That shouldn't happen unless the sources were related. Shared origin? Common technology? Or something influencing the transmissions themselves-some property of local space that imposed mathematical structure?

  Dr. Lira ran probability calculations. The odds of three unrelated sources producing identical ratio patterns by chance: statistically negligible. The odds of it being deliberate: high. The odds of it being natural-some quirk of physics-fell somewhere in between, which made it the most interesting option.

  She cross-referenced the cluster coordinates with astronomical databases. Nothing unusual: standard stellar density, no anomalous masses, no documented spatial hazards. Just empty space that wasn't quite as empty as it should be.

  Dr. Lira made a note: Hypothesis: local spatial geometry affected by unknown phenomenon. Signal patterns are symptoms, not causes. Investigation should focus on environmental factors rather than individual derelicts.

  She forwarded the analysis to Pilot and added a second note: Recommend we take readings at multiple points, not just the signal source. This might be bigger than one derelict.

  Then she sat back and stared at her map, watching the data points float in simulated space. Somewhere out there, something was making space behave oddly. And in approximately seven hours, the Discordia was going to fly right into the middle of it.

  Scientifically, it was thrilling.

  Practically, it was probably a terrible idea.

  But Dr. Lira had long ago accepted that the best discoveries came from terrible ideas approached with good instruments.

  She began preparing her sensor protocols.

  Ven found Dr. Lira in her makeshift lab, surrounded by displays showing waveform analysis. A small potted succulent sat on one console, looking vaguely judgmental.

  "Dr. Lira? Can I ask something?"

  "Always." Dr. Lira didn't look up from her work.

  "Two questions, actually. One: everyone keeps talking about 'the Ship' like it's separate from 'the System.' I understand the System is the AI, but what's the Ship? And two: does that plant have a name?"

  "Yes," Dr. Lira said. "Reginald. He predates most of the crew. Don't touch him - he bites. Metaphorically." She pulled up a structural diagram. "As for the Ship: think of it this way. The System is computational. It processes, analyzes, responds. But the Ship-the physical structure-responds to its environment in ways that go beyond programming. Temperature changes, gravitational stress, spatial distortions. Sira reads those physical responses like an engineer reads stress indicators."

  "So when people say 'the Ship knows,' they mean...?"

  "They mean the Ship's structure is responding to forces we can't directly measure with our instruments. It's not mystical. It's expertise in reading physical feedback." Dr. Lira glanced at Ven. "Though given what we're finding with this spatial phenomenon, the Ship's sensitivity might be more sophisticated than we realized."

  Ven looked at the waveforms. "That's either very reassuring or very concerning."

  "Both," Dr. Lira agreed. "Definitely both."

  Engineering was quiet except for the Ship's usual symphony: coolant pumps, life support, the faint whistle of air cycling through scrubbers. Sira moved through it automatically, checking readouts more out of habit than necessity.

  The author's tale has been misappropriated; report any instances of this story on Amazon.

  The Ship was in good condition. Jump capacitors at full charge, fuel reserves adequate, hull integrity nominal. Everything ready for whatever the crew decided to do with their questionable decision-making skills.

  She rested a hand on the bulkhead and felt the familiar thrum of the Ship's heartbeat. Steady, reliable, unchanged.

  Except it was changed. Slightly. A new harmonic underneath the usual patterns-subtle enough that most people wouldn't notice, obvious enough that Sira couldn't ignore it.

  She closed her eyes and listened. The Ship was humming something it hadn't hummed before. Not distressed. Not alarmed. Just... different. Like it was paying attention to something outside, or inside, or both.

  "You okay?" she asked the hull.

  The Ship's hum shifted pitch slightly-acknowledgment, maybe, or just a mechanical resonance that her brain insisted on interpreting as communication.

  Sira pulled up the engineering logs. No anomalies. No warnings. Everything functioning exactly as designed. But the Ship knew things the sensors didn't, and right now it was trying to tell her something.

  She made a note in her personal log: Ship behavior unusual since departure from Cant. Hum pattern changed-new harmonic present. No mechanical cause identified. Monitoring.

  Then she checked the jump coil-the micro-jump module they'd salvaged and installed against several regulations. It was dormant, as it should be, but Sira ran diagnostics anyway. The module had gotten them out of trouble yesterday, but it was unpredictable. If they needed it again-

  She stopped that thought. No point worrying about emergencies that hadn't happened yet.

  Instead, she focused on the Ship's hum, trying to identify the pattern. It was almost familiar, like a song she'd heard once and couldn't quite remember. The rhythm matched something, but she couldn't place it.

  Maybe it would make sense when they reached the signal source. Or maybe the Ship's structure was just resonating with some external force she hadn't identified yet-gravitational stress, EM interference, something in the fabric of local space.

  "If you're trying to warn me," she told the bulkhead, "a little more specificity would help."

  The Ship hummed contentedly and offered no clarification.

  Typical.

  The coordinates resolved into something visible when we were two hours out from the signal source. Not much-just a dark shape against darker space, no lights, no active emissions. But sensors confirmed it: a derelict cargo hauler, old design, drifting without power.

  "That's it," Tavi said, voice tight with anticipation. "That's the source."

  Dr. Lira's station was alive with data streams. "Confirmed. Signal is broadcasting from the derelict's emergency beacon. Automated, as expected. But here's the strange part-"

  "There's always a strange part," Rafe muttered.

  "-the derelict's position doesn't match predicted drift. Based on the beacon's activation date and local gravitational influences, it should be approximately forty thousand kilometers from its current location."

  Quinn leaned forward. "Chart error?"

  "Possible. Or the derelict moved. Or space moved." Dr. Lira pulled up a simulation. "If local geometry is affected by the phenomenon I've been tracking, drift calculations would be wrong. The derelict didn't move-the space it occupies shifted."

  "Space doesn't shift," Mara said.

  "Space-time can be affected by gravitational fields, relativistic effects, frame-dragging-"

  "Can we table the physics lecture until we know we're not flying into a trap?" I said. "Mara, sensor sweep. Anything besides the derelict?"

  Mara checked her displays. "Negative. No active ships, no weapons signatures, no sensor pings. Just us and the ghost."

  The System helpfully added: "I have compiled a brief historical overview of cargo haulers matching this design profile. Would you like to hear it? It is quite thorough. I have been working on it since we left the Cant. It has footnotes."

  "Not now, System."

  "The footnotes are excellent."

  "Life signs?"

  "None. Derelict's been cold for decades. If anyone was aboard, they're long gone."

  I reduced our approach speed and adjusted our vector. "All right. We're going to maintain safe distance and run a full sensor sweep. Sira, how's the Ship?"

  "Stable," Sira's voice came back. "But it's humming. More than usual."

  "Define 'more than usual.'"

  A pause. "It's like... the hull's resonating with something. Vibration patterns have shifted slightly since we entered this region. Could be gravitational stress from whatever's affecting the space around here. The physics should be straightforward, but I've never seen a response quite like this."

  I glanced at the derelict on my forward display. It looked dead-dark hull, no thermal signatures, no signs of activity. Just a piece of Ningen wreckage that had been floating out here long enough to become part of the background.

  But the Ship's hull didn't resonate at nothing. Whatever was out here was real, measurable, physical. Even if they didn't understand it yet.

  "Noted," I said. "Keep monitoring. If the Ship gets agitated, I want to know immediately."

  We drifted closer, sensors painting a detailed picture: cargo hauler, sixty years old, registry long expired, no salvage claim on file. The hull was intact but pitted with micrometeorite impacts. One of the cargo bay doors hung open, black space visible inside.

  "Looks abandoned," Kellan observed. "Standard emergency beacon, automated distress sequence. Nothing unusual except-"

  "Except it shouldn't be here," Dr. Lira finished. "And those same mathematical patterns are still present in the transmission. Stronger now that we're close."

  Tavi was practically vibrating in her seat. "Are we boarding?"

  "Not yet." I brought us to a full stop at five kilometers-close enough for detailed scans, far enough to run if needed. "Dr. Lira, run your analysis. Tavi, check for secondary transmissions. Mara, sweep for threats. Everyone else, standby."

  The crew went silent, focused on their tasks. Outside, the derelict hung in space like a question no one had asked in decades.

  Dr. Lira's voice broke the silence. "Proximity is intensifying the effect. Whatever's causing this, we're getting closer to the source."

  And underneath it all, barely audible through the hull, the Ship's hum had shifted pitch-matching the frequency of the signal. The Ship didn't elaborate. It never did. But I'd been flying it long enough to know the difference between background noise and an opinion.

  I made a note to ask Sira about that later. After we figured out what we'd found and why it shouldn't exist.
