Chapter 33: Gunpowder

Next to the cement production building, Roland built a new structure.

It was a single large room, three hundred square meters, one entrance. The security arrangements were the most stringent he had implemented in Border Town: two knights at the door at all times, a registration requirement for entry, a body check searching for fire-making tools on anyone who came in. No source of flame inside — production was daylight-only work. He hung a heavy cotton curtain across the doorframe to defeat Nightingale’s invisibility. This last measure he did not explain to Carter.

Carter looked at the grey powder in his hand and sniffed it. “This isn’t snow powder.”

“Similar. An improvement.” Roland took the sample back. “I’m calling it gunpowder.”

Carter had attended enough royal ceremonies to know what snow powder looked like — the fine, silvery-grey product of the alchemical workshops, used for light and spectacle, slow-burning, explosive in a theatrical sense rather than a practical one. What Roland had produced was the same color but different in every quality that mattered.

The formula had not required invention, only memory and correction. Snow powder mixed charcoal, sulfur, and saltpeter at approximately three-to-one-to-one, sometimes with additional materials — mercury, honey, various experimental inclusions — that produced a slower burn and less gas release. The alchemists were working in the right territory but had optimized for the wrong result. They wanted light and smoke, not force. In thirty years, Roland calculated, someone in the kingdom would probably arrive at a closer ratio through iterative experiment. He had arrived there already: one part charcoal, one part sulfur, seven and a half parts saltpeter. The result burned fast and completely, producing a gas pressure that could move a lead ball through an iron tube with enough force to kill at distance.

The gunpowder itself was the new weapon. Not the guns — those were coming, but slowly, four barrels before winter, four guns for four of Iron Axe’s best hunters. The gunpowder preceded the guns and was in some ways more immediately useful. A controlled charge of gunpowder without a gun was still an explosive. An explosive could be placed in a pit, in a trench, at a gap in the wall — triggered by a slow match when the demon beasts reached the designated point in the funneling system he had described to Van’er.

He thought through the geometry of the wall defense while he worked. Six hundred feet across. A hundred militia plus four riflemen. Without the funneling, this was not a defensible position. With it, the front compressed to something that could be held — perhaps thirty feet, perhaps fifty — and the four rifles became a significant force rather than a gesture. A rifle shot from the wall at a compressed mass of demon beasts would not need exceptional aim.

He would need to make gunpowder in quantity before the Months of the Demons arrived. The production was straightforward: charcoal and sulfur were both available, and the saltpeter he had been accumulating via the winter ice crystallization process was building in the locked storeroom. The main variable was time.

He had approximately six weeks.


Carter held the sample up to the light again. The powder was darker than snow powder, more uniform in texture, finer. He watched Roland explain the formula with the same expression he had worn through the steam engine demonstration, through the cement test, through every encounter with something that came out of the prince’s head and into existence: a look that combined reluctant professional respect with a private note that the world was apparently larger than his training had prepared him for.

“It’s a weapon,” Carter said.

“Among other things.”

“And the guns.”

“The guns will be ready by the first demon attack. Four of them.” Roland looked at him. “Iron Axe’s best four hunters. They’ll need practice before it matters.”

Carter set the sample down and looked at the building, the locked door, the guards at the entrance. “You built this to keep it from burning accidentally.”

“Gunpowder ignites from the smallest spark. A lit candle at the wrong moment would destroy everything and probably take half the block with it.” He paused. “And from intentional interference.”

Carter made no comment on the cotton curtain.
