Chapter 46: Prototype V2
The Scar had its position above the roofline, pale and irregular against the morning sky. Beorn stood at the office window, watched it, then shifted focus back to the problem he had been working. The ledger waited on the desk behind him, and his attention returned to mine drainage.
He had started before dawn, working through the requirements step by step. He knew the solution.
But when he tried to pull exact values, the numbers did not match. He could sense where they should be, like a missing segment in a complete system. That was a problem, but forcing it rewarded nothing except a growing ache behind his eyes.
He marked the limitation, stopped the attempt, and moved on. There was a foundry test schedule for the day. That was more valuable than straining for inaccessible figures.
He had been in Ashmark long enough that the exact day count had stopped mattering. More than a month for sure. The sequence of events was clear, even if the total was not.
He had expected dissonance between what he had been and where he was. That had not happened. The prince’s instincts already fit this place, this cold, the weight of the citadel stone in the morning. The other life training had not required a new world, only new materials and constraints. Those could be worked.
The initial conflict between those two sets of instincts had stabilized. He noted that and chose not to pursue it further. The ledger was on the desk. He picked it up and left.
The corridor signaled the foundry before he reached it. Heat had been building in this wing since the first pour, trapped and steady, layered over the cooler stone that had not yet absorbed the furnace output. He felt both temperatures as he pushed the door open.
Wynn stood at the boiler with both hands resting on the casing. He looked up as Beorn entered.
"The cold water tank’s full," Wynn said. "I topped it this morning. If it fails again, that won’t be the cause."
"The bore is different from last time," Beorn said.
Wynn paused, "How different."
"Enough to justify another test," Beorn said. He set the ledger on the mold table.
Wynn accepted that with a low acknowledgment and turned back to the boiler. His men were already in position. One at the injection valve. One monitoring the beam bracket from across the room.
Aestrith had entered without drawing attention. Beorn did not see her come in. He only noticed her presence along the wall near the mold table, arms crossed, watching the engine with focused familiarity. She understood enough to observe without instruction.
Wynn initiated the firing sequence.
The system moved through its heat cycle in predictable stages. Beorn tracked each phase.
When the pressure reached Wynn’s target threshold, Wynn stepped to the cylinder and held his hand near the valve housing. He did not touch it. He watched the pressure gradient through the air, confirming the seal integrity.
After several seconds, he gave a small nod to the man at the injection valve.
Cold water entered the chamber.
The response transmitted through the floor before it reached Beorn’s ears. A solid impact. The mechanism completing a cycle.
The piston drove down through its full stroke. That was the first critical check.
The rocking beam pivoted on the ceiling bracket with full transfer of motion.
The far arm rose cleanly, engaging the pump linkage. Across the room, water began moving through the test pipe.
The engine was functioning.
No one spoke during the next four strokes. They observed, listened to the rhythm as it established itself.
A repeating mechanical cycle that had not existed in this world before now.
After the sixth stroke, Wynn raised his hand. The man at the injection valve closed it immediately.
The engine began to wind down. The beam lost momentum, the pump dripped, then stopped.
Wynn moved to the pump assembly and crouched beside the output pipe. He tapped the pipe wall twice with his knuckle, just below the fitting, then listened to the return tone. He was checking for loosened joints under vibration.
He moved to the second fitting and repeated the test.
He stood and faced Beorn.
"Boiler fired clean," Wynn said. "The piston completed the first stroke and maintained function through six."
He paused briefly, not searching for a problem, only completing the report.
"The pivot still has play. You’re losing efficiency during recovery."
"I see it," Beorn said. He was already marking adjustments in the ledger. "The loss is acceptable for current needs. We proceed and correct the pivot in the next iteration."
Wynn considered that. "Do you want to use this version on the field?"
"Yes. This week."
Wynn did not argue. He turned and began issuing movement through action rather than words. His men followed. They exited the foundry.
The door closed. The system entered a passive state, heat dissipating, iron cooling.
Aestrith stepped away from the wall and approached.
She stopped beside the beam and looked up at the pivot bracket. That joint had been modified from the first version. She studied it, then shifted her attention to the pump assembly, then to Beorn.
"So," she said.
She wanted the next step defined.
"The flooded mines closest to the city," Beorn said. He rotated the ledger toward her and tapped the diagram. A cross-section with tunnel walls, a waterline and pressure vectors from surrounding rock.
"When a shaft floods, the water supports the walls. If we remove the water quickly, that support disappears and the walls take full load immediately."
He met her eyes. "They collapse."
She analyzed the diagram. "So you need support during drainage."
"Yes."
"And you intend me to provide that support."
"I like your initiative," he said. "It’s simple in theory, but I’m unsure on practice."
She looked at him directly, testing the assumption.
"I don’t know if I can either," she said. "In a shaft, I’d be inside what I’m holding."
"Yes."
"And if my effective range doesn’t cover the entire section while I’m at the center?"
"I don’t have exact limits yet," Beorn said. "But we can work with a margin for error at the start."
She looked back at the diagram.
He watched her process the task. The water would be removed, the pressure would change, the risk of collapse and her role in countering that. He did not interrupt. It was better if she thought of it in her own terms.
"So your plan," she said, "is to take me underground into a shaft that’s been flooded long enough to be unstable, and have me hold it together while a machine we just confirmed for six strokes removes the water."
"Correct," he said optimistically, "Safety methods included."
She exhaled slowly through her nose. "And I was just starting to get used to working with molds."
She turned and left through the secondary corridor.
The door closed behind her with a firm latch.
