Chapter 51: Drainage
The first impact reached him through the ground before his hearing caught up. It traveled up through Beorn’s boots as a deep mechanical knock, the rhythm from the earlier test, but the environment changed its character. Rock vibrated differently than a warehouse floor. The second stroke followed at its expected interval.
Within two minutes, the drainage channel showed visible flow. Water emerged from the outlet pipe at a steady rate. It spread into the cut earth channel and began moving toward the lowest point as intended. One worker crouched near the outlet, watching carefully. He tracked the flow for a full minute, then shifted his attention to the foundry-trained operator who had come specifically to run the engine.
"Come on now girl. Keep at it," the foundry man said to the engine. He moved on to inspect the pump fittings for irregularities.
Osen leaned over the shaft collar to observe conditions below. The water surface was in motion. The engine worked in discrete strokes, so the descent was incremental. Still, it was consistent. He straightened without comment and moved away, to inspect the south side from the exterior as the water level dropped.
Beorn and Aestrith approached the shaft before the rope system had been fully secured on the platform pulleys. The earlier they positioned, the more they could observe.
"From this position," she said, considering the distance, "I can manage the south wall while it stays within range. Once it drops below that, I will need to be down there."
"I know," he said. "We lower the platform with the water."
The platform required two men to guide it through the collar. It was rough timber, made to be reliable. They had built it from cart materials during setup and tested it once under load using stone. It fit inside the collar with only a few inches of clearance.
Beorn stepped on first. She followed. The workers above began lowering them in minor increments, controlling descent through the rope.
Inside the shaft, the spatial perception changed immediately. The walls felt closer than they had from above, the lamp cast uneven shadows across layered rock surfaces, distorting depth, the mineral scent intensified, the air temperature dropped enough that the difference was obvious on their breathing.
The engine’s periodic vibration transmitted down through the rope and into the platform boards, reinforcing the mechanical rhythm.
At their current depth, approximately fifteen feet below the collar, the south face crack was directly ahead. At the lower end of the visible section, a small debris accumulation rested on a ledge. Below that, the water surface sat another five feet down. It reflected the lamp in a broken, shifting circle.
Meanwhile, Aestrith was not idle. She watched the crack. Then the opposing wall. Then she estimated the depth to the east gallery side, which was still relevant.
She was reconstructing the three-dimensional structure mentally, even if she didn’t quite understand the theoretical knowledge behind it.
"How are you feeling, up to the task?" he said.
"Watch me."
The water level continued to fall. Above them, the engine maintained its cycle.
Eventually, the water surface dropped below the fractured zone. The lower part of the crack became fully visible. Beorn focused on the debris resting on the ledge, where one fragment in particular stood out. It had been unsupported for some time, its weight suspended between water pressure below and friction against surrounding material. Based on that, it should have fallen once the supporting pressure dropped.
It did not.
Osen descended along the main rope, carrying bundled timber props under one arm. His movements were efficient, the product of long familiarity with the job. He stabilized himself easily and worked beside the platform without requesting space.
He set each prop base, drove the wedge, applied pressure to test stability, then moved to the next. He did not examine the wall as a whole. He focused only on placement points and executed.
When he finished, he signaled for ascent and returned upward without comment. The wall was still stable. Aestrith finally let it go.
Her breathing changed immediately. It slowed, transitioning into recovery. She sat at the end of the platform, hands resting flat on the rope beside her for stability. He watched the change but did not comment.
The water continued to drop while the crew above completed the propping sequence.
Beorn waited until Aestrith propped herself up and gestured to him with her chin. He stopped for a second, but then signaled the workers above to lower the platform further.
At approximately forty feet, the east gallery came into lamplight.
The timber there had swollen against the rock. Up close, the condition was worse than it had appeared during the earlier inspection. The fracture around its upper side remained at roughly an inch, however, the surrounding rock showed fine stress cracks.
She remained standing this time. One hand held the rope. The other stayed at her side, ready.
The water surface sat eight feet below them. When it dropped past the timber, the load came down. Aestrith didn’t voice the challenge, she silently kept still, hidden, single-handedly preventing an entire mine from a collapse. The effort to hold against gravity transmitted to her body in the cost necessary to keep it together.
The crew required more time to secure the east gallery. The foundation was more complex, and they couldn’t simply replace the timber. They had to reinforce it.
Beorn tracked the fracture above continuously. It did not widen. The wall remained stable. She maintained position.
By the time the crew confirmed the props were properly seated, Aestrith had strained her powers significantly longer than before. Beorn did not wait for full clearance.
He gave the signal.
Her exhale followed immediately. It was complete, audible in the confined shaft. She sat on the platform and paused before speaking.
"Get us out of here," she said.
He signaled. The platform began to rise.
As they ascended, the mine walls showed the results of the day’s work. The waterline had dropped enough to expose several feet of previously submerged rock. The surfaces were dark from prolonged saturation.
When they cleared the area, Osen was already waiting for them. He looked first at Beorn, then at Aestrith.
"It went better than I expected," he said. The comment was general, not directed.
Wulf observed from the engine position. His attention went to Aestrith.
Her condition was evident, pale, trembling with exhaustion.
Wulf looked at Beorn. "Is she all right?"
Aestrith answered before he could. "He brought me on a day-long road trip, lowered me into a mine shaft, and had me hold a lamp the entire time." She turned her head slightly toward Beorn. "I said I should have stayed in Ashmark."
There was a brief pause. Beorn processed the implications. He felt like a spoiled noble prince that couldn’t spend a day without his secret mistress.
"Your company... was necessary" he said.
She gave him a look he recognized. He had to play further into it.
"For... reasons. Private, reasons." he added, adjusting.
"Those reasons can very much stay to be done in a bedroom," she said.
Wulf averted his eyes away from the exchange. His expression one of scorn when he glanced at Beorn.
Osen made a short sound, indistinct, and walked toward the drainage channel.
Aestrith stood and moved toward the engine carts without looking at Beorn. He followed at a distance.
The engine continued running through the afternoon. By the time the sun shifted west, the shaft had drained enough to fully expose the ore band along the upper walls. It formed a consistent dark line. Beorn stood at the collar and studied it.
This established the first mine as operational.
The second mine presented similar conditions. Groundwater flooding, no reported monster activity.
The third mine had a monster nest. That would require an extermination campaign, but Beorn wasn’t inclined to send one without at least equipping his militia with rudimentary firearms first.
However, that would require nitre and more.
He opened the ledger to a new page and recorded a single line for the official record. Then he closed it.
The engine continued its steady interval. The drainage channel carried the flow.
