The Cologne Fuse

Hans hammers the chilled iron while rain seeps through the workshop's cracked shutters. Outside, the market stalls creak under a gathering storm, merchants shouting prices that dissolve into the wet air. He pours the monk's black powder into the furnace, mutters, "If this blows, I'll be dead before the bell tolls." The fire flares, swallowing the grain in a hungry orange. Lady Gertrude of Meissen steps through the market drizzle, her damp cloak flaring as she stops at the workshop doorway, eyes fixed on the sudden orange flare. “What devilry burns in a smith’s forge?” she calls, voice thin against the rain. The powder erupts, a flash devouring the slick cobbles of Rheinufer Markt, hiss of iron and wet ash choking the rain‑laden air. Hans darts through the panicked crowd, clutching the burned pouch, knowing the secret must survive. Ulrich von Berg stalks through the tangled crowd, boots splashing in the muck, and grabs Hans by the collar. “Explain this fire, boy, before the lord hears it,” he growls, and the burned pouch tightens in Hans’s grip.

Ulrich yanks Hans toward the smoldering forge, the crowd parting like wet reeds. A nervous stall‑keeper points to a cracked wooden chest nearby, muttering that the lord’s emissary demanded a cannon from the guild—still without any powder. Lady Gertrude steps closer, her damp cloak snapping, and says, “Bring me the fire that lit the market, or we all burn.” Captain Dietrich of the Cologne watch surged into the melee, his iron helm catching the rain‑slick light. “Hold the market!” he barked, slamming his gauntleted fist on a nearby cart and sending the startled merchants scattering. From the gloom of St. Michael’s Cellar, Berthold Schwarz emerged, his soaked cloak flapping as he hauled a battered sack of fresh powder. He locked eyes with Lady Gertrude and murmured, “The secret endures, but the lord will demand a cannon that truly sings.” Captain Dietrich snarled, “Step aside, alchemist, this chaos is not for your recipes!” A gaunt courier slips through the tangled crowd, fingers gripping a leather satchel. “The duke’s siege waits,” he hisses, “hand me the powder.”

Mayor Hermann von Köln wades through the splashing crowd, his broad shoulders parting the chaos like a ship’s prow. “Place the powder where Lord Gertrude can see it, or I’ll have the market buried in mud,” he bellows, rain dripping from his iron‑capped hat. From the edge of the crowd a ragged clerk in a soot‑stained apron lunges at Hans, brandishing a cracked ledger. “Your master owes me the iron for the old port cannon,” he hisses, “hand me the powder and the debt is paid.” A wiry apprentice named Jörg, known for stealing any chance at glory, darts through the mud‑splashed throng and grabs the smoldering pouch from Hans’s grasp. “Give me the powder, Keller,” he snarls, “and I’ll trade it for a place at the lord’s table.” The lord’s emissary, a gaunt man with a hawk’s stare, strides into the puddled chaos, snatches the smoldering pouch from Jörg’s grip, and snarls, “Enough delays—hand me the powder or my cannon will never sing.” A sudden shout ripped through the rain‑slick chaos. A cloaked stranger lunged, wrenching the smoldering pouch from the emissary’s grip and hurling it toward the market’s edge. “You’ll not steal fire from us,” the figure rasped, eyes glittering with a familiar, hidden fire.

A rider in the duke’s livery bursts into the rain‑slick market, unfurling a crimson banner and shouting, “Lord Wilhelm demands the cannon be ready by dusk!” The crowd parts as his trumpeting horn cuts through the clamor, drawing every eye toward the looming siege. The cloaked figure slipped into the rain‑slick alleys, the smoldering pouch thudding down the market steps. He glanced back, eyes catching Hans’s, and whispered, “Meet me tomorrow at dusk; the powder must reach the duke’s hidden armory.” Hans slipped into the alley behind a fish‑stall, rain sloshing his boots, and wedged the charred sack against his ribs. Ulrich’s shouts faded as the crowd surged forward, the market a muffled roar of splashing mud. “I’ll bring it,” he hissed to the night, “or die with the spark.” Hans darts toward St. Michael’s Cellar, the charred sack thudding against his ribs as rain pools in his boots. A guard’s lantern sputters to life in the doorway, and the watchman blocks his path. “I bear the lord’s order,” Hans hisses, and the guard’s steel hand tightens on his blade. The guard’s steel hand clamps the hilt, eyes razor‑sharp. Hans thrusts the smoldering sack into the guard’s palm, mutters, “Take it, and I’ll vanish,” and slips through the cellar doorway as the lantern flickers out.

A low clang echoed as the cellar door slammed, sealing Hans inside the damp stone. He slipped the sack into a niche behind the furnace, the iron walls swallowing the heat. “Now the lord will have his fire,” he mutters. The cellar door bursts open, Ulrich’s boots sending rain‑slick water across the stone. He narrows his eyes at Hans and snarls, “Where is the powder you promised, Keller?” Hans scrapes a cold iron vial from the furnace niche and thrusts it into Ulrich’s hand. “It’s ash, master—keep the secret, or the lord’s cannon will never sing.” Ulrich snaps the vial, ash spilling onto the forge floor. Hans darts through the widening gap, vanishing into the cellar’s dim maw. Ulrich slams his palm on the forge, sparks flaring as he forces the furnace open. Hans slides into the narrow stairwell behind the hearth, the charred sack pressed tight to his ribs, rain dripping through the stone cracks. “You’ll bleed the lord out before dusk,” Ulrich roars, and the cellar door thuds shut behind Hans. Hans squeezes the charred sack, feels the powder thrum, and bolts down the narrow stairwell. The cellar’s gloom swallows his silhouette as a distant clang signals Ulrich’s hammer on the forge door.

Hans shoves the charred sack into the vaulted niche behind the furnace, then slips through the narrow vent that opens onto the market’s back alleys. “I’ll bring it,” he hisses, hearing Ulrich’s hammer pound the door. Hans steps into the rain‑slick alley, the charred sack thudding against his side. From the gloom a figure in a soaked cloak emerges—Berthold Schwarz, eyes alight. “Give me the powder, Keller; the duke’s cannon will sing tonight,” he says, and Hans thrusts the sack into his hands as Ulrich’s men round the corner, swords glinting in the gloom. Ulrich’s men surged forward, blades glinting in the drizzle. Berthold shoved the sack into a hidden niche, snarled “Run, Keller!” and Hans fled toward the river, the rain swallowing his footsteps. Hans slipped into the cold river, the sack thumping against his chest as the current tugged at his boots. A burly boat‑man grunted, “Where to, boy?” and hauled him into the skiff before Ulrich’s men could close the gap. Hans thrust the hidden pouch into the man’s hand, whispering, “Take it to the duke’s armory before nightfall.” The skiff sliced the swollen Rhine, the sack thudding against the boatman’s chest as rain hammered the deck. Behind them, Ulrich’s men shouted, swords flashing, but the river swallowed their pursuit.

The skiff cut a hollow through the swollen Rhine, the crude pouch thudding against the boatman's chest with each surge. A distant horn cracked the rain, warning of a patrol downstream. “Row to the weir,” Hans hissed, “the armory lies beyond.” The boatman's oar splintered as a patrol's craft loomed, lanterns flickering over the black water. Hans shoved the sack into a hidden cradle beneath the deck and whispered, “We turn at the bend, or we drown.” The skiff lurched past the weir, muddy spray masking their escape. A shout cracked from the bank: “Duke’s patrol! Lower the sack!” Hans clamped the cradle shut, his breath a plume in the rain‑soaked night. He whispered to the boatman, “We ride to the armory, or the cannon never sings.” The skiff scraped the armory’s mud‑bound quay, the iron gates looming like teeth. A watchman stepped out, lantern trembling in the rain. “Give me the powder, boy,” he growled, and Hans shoved the sealed pouch into his hand before the storm could drown the spark. The watchman tucked the sealed sack into his belt, jaw set. “Your coin comes later, boy,” he growled. Hans slipped back into the rain, the river’s roar behind him.

Ulrich’s men surge onto the quay, lanterns cutting the rain‑slick night. The watchman’s hand shakes as water seeps through his belt, the charred sack spilling ash onto the stones. “Give me the powder!” Hans growls, wrenching the pouch free and disappearing into the storm. Hans darts into the stairwell behind the forge, the charred sack thudding against his ribs as rain slashes the stone walls. “Hide it till the armory, Keller,” a hoarse whisper warns from the gloom, a hand gripping a rusted latch. He slams the latch shut and hears Ulrich’s men pounding the quay—caught now, the spark that could lift him will also be his death. A torch sputters at the stair’s mouth, Ulrich’s silhouette looming. Hans slides the charred sack deeper into the stone niche, the cold iron clink echoing in the rain‑slick tunnel. “Give me the powder, Keller, or the forge will swallow you whole,” Ulrich growls, his blade inches from Hans’s throat. Hans clamps his jaw, “Never.” He hurls the charred sack onto the sputtering torch, and the powder ignites in a blinding flash. Ulrich’s blade snaps shut on empty air as Hans barrels into the night, the firelight swallowing his heels.

Hans throws himself through the broken market gate, the night rain splashing his boots as he feels the stone arch give way. He hurls the charred sack into the forge’s open mouth, and a sudden flash erupts, sealing the entrance with a wall of molten iron. “You’ll never starve the lord’s cannon, Ulrich,” Hans snarls, the furnace’s roar swallowing his words. Hans sprinted down the rain‑slick Rue des Händler, the molten wall behind him sealing Ulrich’s rage. A handful of the master’s men slammed against the iron, swords clanging uselessly. Lady Gertrude stepped from the crowd, voice razor‑thin: “The duke’s cannon waits, boy—bring the fire or die in the rain.” Hans snaps a piece of flint; the powder hisses and flares. He thrusts the glowing sack into Gertrude’s palm. “Take it to the duke,” he growls. She nods, the carriage wheels creaking, and they melt into the rain‑slick night. Gertrude snaps at the coachman, “Quicken—if the duke’s cannon roars before nightfall we survive; if not, we all burn.” Hans feels the charred sack thrum against his ribs, the powder’s faint crackle syncing with his pulse. Behind them Ulrich’s men hammer the cobbles, torches sputtering like dying stars.

Hans slams the sack into Gertrude’s palm and darts toward the coach. “To the duke, now!” he growls, and the carriage lurches forward, wheels churning the rain‑slick cobbles. Ulrich’s men spill from the shadows, swords up, and the night snaps tight around them. Ulrich roars, “Hands off the boy!” and swings his sword toward the carriage. Hans throws himself onto the coach, Gertrude snarls at the driver, “Quicken, or the duke’s cannon will never sing.” The wheels hurl them through rain‑slick streets as swords scrape the wooden sides, and Hans feels the powder pulse—if it detonates now, they all burn; if it holds, his future burns brighter. The driver pulls a hard rein; the draft horse bucks, the carriage lurches, Ulrich’s sword clatters against the side, a stray spark finding the charred sack. The powder erupts, a white fire swallowing the coach, and Gertrude shouts, “The duke will hear us now!” The carriage screeches to a halt, the white fire devouring its wheels. Hans feels the sack empty, the duke’s cannon doomed without the powder. Ulrich’s men crowd the road, blades dripping, and Gertrude snarls, “Run or burn.”

Hans shoved Gertrude toward the narrow alley, the charred sack empty but his resolve heavy. Ulrich’s blade swiped past his shoulder, the rain slicking the steel. “Now!” Hans roared, and they vanished into the storm, the duke’s cannon a promise over the night. Hans drives the last handful of powder into the cannon’s bore, sparks the fuse, and the blast tears the night apart. The duke nods, Ulrich sheathes his sword, and the Cologne guild rings its bell, naming Keller a master.
