The first city trip came without warning.

  "I'll be gone for three days," Havelock announced at the end of a Tuesday. "Business with suppliers. Tommin will run the workshop. Keep working on the prototype. I want a full week of pressure readings by the time I return."

  "Three days?" Eiran had never known Havelock to leave Kettleford for more than an afternoon.

  "The journey alone takes a day each way. And I have meetings." Havelock was already packing his travel case: papers, a change of clothing, the leather satchel that held Eiran's notes. "You have everything you need here. Just keep recording."

  The workshop had just shipped the three Thornbury chronometers, delivered on time to Havelock's visible relief, and whatever goodwill that commission had bought, he'd immediately converted into travel plans.

  He left the next morning, before dawn, catching the mail coach that ran twice weekly between Kettleford and the city.

  Eiran kept recording.

  The prototype sat on its dedicated shelf, mercury column rising and falling with the invisible pressure of the air. He took readings every four hours, logging the numbers alongside weather observations. The correlation was emerging clearly now: pressure drops preceded storms by twelve to eighteen hours, pressure rises preceded clear weather. The pattern was real.

  He wished he could share that excitement with someone. But Tommin was focused on the regular commissions, Pol was too young to understand, and Havelock was gone.

  Three days stretched into four, then five. When Havelock finally returned, he looked tired but satisfied.

  "Good news?" Eiran asked.

  "Promising." Havelock set down his travel case without elaborating. "How are the readings?"

  "Strong correlation. The pressure dropped twenty-six hours before the storm on Friday. Rose steadily after it passed."

  "Excellent. That's exactly what we need." Havelock pulled papers from his satchel, not Eiran's notes but new documents, printed and official-looking. "The journal is interested. I've submitted a preliminary proposal. They'll want the full paper by month's end."

  "That fast?"

  "That fast. Which means we need to accelerate our timeline." Havelock spread the papers on the workbench. "I've outlined the structure. Introduction, theory, methodology, initial findings, applications. If you can provide more specific data by next week, I can incorporate it into the submission."

  They worked through the evening, organizing the readings into tables, refining the theoretical framework, polishing the descriptions of the compensation mechanism. Havelock asked questions that probed deeper than before: the exact ratios, the specific calibration procedures, the mathematical relationships underlying the predictions.

  Eiran answered everything. The knowledge was still there, clear and accessible, waiting to be translated into language the journals would accept.

  By midnight, they had a draft.

  "I'll clean this up tomorrow," Havelock said, gathering the pages. "There's a coach the day after. If I leave early, I can deliver the full submission in person."

  "Another trip?"

  "The city connections require maintenance." Havelock's smile was strained. "You understand. I wouldn't go if it weren't necessary."

  ---

  The trips became regular.

  Every week, sometimes twice a month in the busiest stretches, Havelock would pack his travel case and catch the morning coach. The journeys cost money, two or three royals each time for coach fare, lodging, and meals. Money the workshop didn't seem to have.

  "Where is it coming from?" Eiran asked Tommin one evening, when Havelock was gone again.

  "Where's what coming from?"

  "The travel money. The city trips. The coach fare alone must be-"

  "Not our business." Tommin's voice was flat. "I do my work. I get my pay. What the master does with his time and money is his concern."

  But the next day, Tommin pulled Eiran aside.

  "You want to know about the money? Talk to Pol's uncle. He does deliveries for the suppliers. He's heard things."

  Pol's uncle was a thin, nervous man who hung around the Muddy Boot most evenings. Eiran found him there, nursing an ale and watching the room with the wary eyes of someone who knew too much about too many people.

  "Havelock's workshop?" The man snorted. "In debt up to the eaves. Owes forty royals to Aldworth and Associates. That's the patent protection fee he hasn't paid. Owes another twenty to the brass supplier in the city. And that's just what I know about."

  "Sixty royals in debt?"

  "At least. Word is he hasn't paid Tommin in three weeks. The senior lad's been living on promises." The man took a long drink. "If you're smart, you'll look for other work. That workshop's going under before spring."

  Eiran walked home slowly, the cold biting through his coat.

  Sixty royals. Maybe more. And Havelock was spending two or three royals a week on city trips, traveling to meet with journals and contacts and whoever else demanded his presence.

  Where was that money coming from?

  And more importantly, what did it mean for the partnership Havelock had promised?

  ---

  The dream fragments returned.

  Not the full experience, not years of mountain living or the complete immersion in Coren's life, but echoes. Flashes of the stone workshop, glimpses of charts and readings, moments of insight that surfaced from nowhere.

  Eiran would be working on the prototype and suddenly know, without thinking, that the mercury needed to be purified differently. Would be calibrating the scale and understand, without learning, that the temperature compensation required a specific ratio of metals.

  The knowledge kept coming. Unpacking itself, as he'd told Havelock. Revealing layers he hadn't known were there.

  He added to his notes. Refined the design. Improved the calibration methods. Each improvement made the prototype more accurate, the correlations more reliable.

  But Havelock wasn't there to see it.

  The trips continued. The absences grew longer. And when Havelock was in the workshop, he was distracted, impatient, focused on correspondence Eiran couldn't see.

  "The paper," Eiran finally asked, during one of Havelock's brief appearances. "How is it progressing?"

  "Well. Very well." Havelock didn't look up from the letter he was writing. "The journal reviewers are impressed with the preliminary findings. They want more data, but they're impressed."

  "Should I prepare additional readings? I have three more weeks of observations now-"

  "Yes. Yes, do that." Havelock folded the letter and sealed it with wax. "Organize everything clearly. Tables, charts, whatever makes the patterns obvious. I'll incorporate it into the next revision."

  "When will that be submitted?"

  "Soon. Soon." The letter disappeared into Havelock's satchel. "I need to catch the afternoon coach. Keep recording. We're close to something real."

  He was gone before Eiran could ask what that meant.

  ---

  That night, the dream came stronger.

  Coren again, but older now, ancient really, bent with age and weathered by decades of mountain winters. He sat at his workbench, surrounded by charts and records, the accumulated proof of a lifetime.

  And he was dying.

  Eiran felt it as Coren felt it: the weakness in the lungs, the cold settling into bones that would never be warm again. The storm season was coming, and this time Coren wouldn't survive it. He knew this with the calm clarity of a man who had made his peace.

  The records were what mattered. The truth was what mattered.

  He spent his last days organizing. Labeling the charts. Writing explanations that any educated reader could follow. If someone found his workshop after he was gone, if some shepherd or traveler stumbled across the stone hut and looked inside, they would find proof. Real proof. Undeniable evidence of a truth about the world.

  The pressure of the air. The weight of the sky. Measured, recorded, understood.

  It didn't matter who got the credit. It only mattered that the knowledge survived.

  Eiran woke.

  The dawn was grey and cold. His body ached with phantom age, muscles sore from decades of work he'd never actually done. The hunger was there again, sharp and demanding.

  He ate what food remained and thought about Coren's final days. The organization. The labeling. The faith that someone would find the truth and carry it forward.

  Coren hadn't cared about credit. Hadn't cared about recognition, about patents, about the journals that had rejected him.

  But Eiran wasn't Coren. Eiran was young and alive and desperate to be seen. The truth mattered, but who discovered it mattered too. Who got credit. Who profited. Who was lifted from poverty and obscurity into something better.

  He went to the workshop and took more readings and waited for Havelock to return.

  The partnership was real. It had to be real.

  Anything else was unthinkable.
