The lanyard snapped taut beneath Giles’s leather glove.
At that instant, two disparate physical forces—ancient clockwork twisting force and modern magnetic lorentzian gaining speed—fused into a singular, total impulse.
First came the clockwork release. The four pre-stressed layered alloy leaf springs, wound to two hundred thousand foot-pounds of stored clockwork potential energy, whipped forward with an explosive metal crack. The heavy bronze armature carriage slammed into the breech, launching the thirty-eight-two-pound sabot assembly down the cold-broached rail guide at nearly six hundred feet per second.
Then the spark circuit closed.
The sabot’s copper contact brushes bridged the eighteen-foot rails. Then, the thirty Leyden-jar charge banks discharged fifty thousand current units of direct current into the track. A blinding flash of blue-violet arcing light lit up the entire riverport, casting razor-sharp shadows across the timber stronghold.
The magnetic Lorentz force seized the sabot, wildly speeding up the projectile down the guide rails with the wrath of an artificial lightning bolt.
CRACK-BOOOOOOOOM!
It wasn’t the dull, rolling boom of a black-powder cannon, nor the whistling shriek of a royal catapult stone. It was a terrifying, ear-splitting faster-than-sound blast. The sound of the sky envelope being ripped open along a clean, empty pocket-sealed sharp-angled line.
The faster-than-sound blast wave washed backward over the low roof wall. Borin Bronze-Lung’s pipe was sucked clean out of his breast pocket, tumbling into the mud below. Three glass check panes on the rear survey shack shattered into glittering rain. Captain Kenneth Drake, his jaw open just as Giles had commanded, felt the blast strike his teeth like an iron mallet, rattling his very skull within his helmet.
At the muzzle, the four-petal light metal-alloy sabot shoes peeled open against the faster-than-sound air pushback. With a shower of white-hot friction sparks, the sabot petals tumbled harmlessly away. It splashed into the river canal fifty yards out.
Free of its carrier, the naked needle flew.
It was a sixteen-inch rod of sintered heavy dark metal-hardened carbon-iron alloy, barely an inch and a half in width, fin-steadied and screaming across the Black Fens at nine hundred and fifty meters per second—Mach two point eight.
Across the intervening eighteen hundred and fifty yards of drained peat basin, the Three-Headed Mire-Hydra was in the final stage of its bio-arcane discharge. Its three snake-like gullets were swollen with blazing bright, skin-burning green bile. The air around its jaws was already dissolving into yellow, choking vapor.
Surrounding the titan, the nonstop emerald water-pressure mana-shield glowed with blinding intensity. A seamless, thirty-yard sphere of condensed aether, total and iron-hard according to every scripture ever scribed by the mages of the Second Cataclysm.
The heavy dark metal dart crossed the mile of open air in less than two seconds.
Then occurred the phenomenon that would forever rewrite the military stonework of Aethel-Terra.
The hydra’s mana-shield had a physical membrane thickness of roughly three inches. At nine hundred and fifty meters per second, the heavy dark metal needle reached the outer surface and plunged through.
The interaction duration was exactly thirty-one point six split-seconds.
The hydra’s central neural mana-nodes, distributed along its spinal crest, possessed a natural replenishment latency of two hundred and fifty split seconds. For a magical defense to absorb or scatter striking force, its ringing mana-lattice must detect the warping, channel aether from next-door reserve nodes, and equalize the water’s skin.
That process needed a quarter of a second.
The heavy metal dart didn’t give it a quarter of a second. The sabot gave it zero point zero three one seconds.
To the mana-shield, the impact didn’t exist. There was simply no time for the lattice to propagate a single wave of defensive pushback.
Also, the needle packed seventeen point one megajoules of striking force onto a tiny frontal area of twelve square inches. A nearby striking force thickness of fourteen thousand three hundred megajoules per square meter, exerting an instant nearby shear pressure exceeding nine gigapascals.
The result was clean, total shear failure.
The heavy dark metal needle didn’t shatter the shield. It didn’t trigger a cascade of sparks, nor did it cause the emerald sphere to ripple.
With a sound like a tailor snipping a thread of silk, the sabot punched a perfectly circular, thirty-tiny hole through the green mana-membrane.
The leftover ninety-nine point nine percent of the huge emerald sphere remained hovering in the air, fully untouched, utterly unaware that its outer edge had been violated.
Across the twenty feet of dead space between the inner shield wall and the beast’s flesh, the sabot screamed on.
It struck the hydra’s central snake-like neck directly at the junction of the collar bone plates, exactly where the main draconic mana-core sat anchored in living muscle.
THWUMP-CRACK!
The seventeen megajoules of striking force, held intact through the barrier, discharged directly into the beast’s vital organs.
The faster-than-sound shifted weight excess pressure and cone-shaped spall fragments blew up inside the central torso. The middle neck didn’t merely bleed. It burst outward in a violent, fiery fountain of purple gore, crushed scales, and shattered spine bones. The central head was cut cleanly at the base, tumbling forty feet through the air before splashing into the peat muck like an overturned longboat.
The heavy dark metal rod punched fully through the three-foot-thick chest bone, crushed the central heart. Then it exited out the hydra’s lower spine, boring ten feet deep into the solid dark rock bedrock beneath the marsh with an echoing, underground thud.
For one suspended, impossible second, the battlefield was frozen in total silence.
Out on the fen, the hydra’s two leftover heads snapped wildly to the left and right, their eyes filled with utter, blank confusion. They looked at the empty stump between them. There, a six-foot geyser of steaming purple ichor was pumping into the gray drizzle.
Then, the central neural nexus collapsed.
Deprived of its main heart and core, the huge emerald mana-shield didn’t fade. It shattered.
The thirty-yard green dome exploded into millions of harmless, glittering emerald flakes that drifted downward through the mist like radiant snow.
The sixty-foot monster groaned—a wet, bubbling death-rattle from its surviving throats—and collapsed forward.
THUUUUUUUUD!
The impact of forty tons of dead draconic flesh sent a two-foot wave of peat water surging outward across the newly drained basin. It splashed against the canal levees with a heavy, final slap.
The Three-Headed Mire-Hydra lay motionless in the mud, dead before its brain had registered the sound of the gun.
On the timber low roof wall of the riverport stronghold, nobody spoke.
Nobody breathed.
Master Borin Bronze-Lung’s hands were plastered to his face. His eyes stared through his fingers at the smoking carcass a mile away. His braided copper beard was trembling so wildly that the bronze rings woven into the hair clinked against each other like funeral bells.
“It... It didn’t even pop the ward...” Borin whispered, his voice cracking into a thin, scared wheeze. “The shield was still standing... And the beast was already dead... By the deep roots of the world, what manner of god-killing needle did we forge?”
Beside him, Captain Kenneth Drake sank to both knees, his ten-foot trenching rod slipping from his grasp and clattering onto the timber decking. He stared at Giles as though the man standing beside him were not a royal noble, nor a mortal builder. But an ancient headsman who had stepped outside the cosmological design to snip the threads of fate.
“A mile...” Kenneth croaked, his voice choked with awe. “A mile away through an ancient god-barrier... With a single shot...”
Sister Teresa dropped prostrate upon the wet spruce planks. She pressed her cheek against the cold wood. “The Brass Needle of Judgement! The Master of Measures has measured the span of the monster’s life, and found it wanting! Let the earth bear witness to the holy shape!”
Giles, however, was not looking at the dead hydra.
He was standing behind the rail-lance’s recoil carriage, his brow furrowed in deep, irritated dissatisfaction. He pulled his wooden ruler from his pocket and measured the distance between the bronze carriage stop and the rear timber bumper.
“Unacceptable recoil travel,” Giles muttered, shaking his head with bitter disgust. “The carriage stroked seven and three-quarters inches. Design limit was six inches. Who blended the high-pressure buffer fluid?”
Toby Karr swallowed hard, scrambling forward with his notepad. “I-I used the pressed stone oil from the north storehouse, Lord Giles!”
“The thickness was two centistokes too light, Toby,” Giles said. He tapped the high-pressure metal tube with his rule. “The damping orifice passed the fluid too quickly, causing too much dynamic slowdown loading against the mounting bolts. If we had fired a fifty-two-pound penetrator, the shear pins would have stripped and taken your shins off. Drain the stone oil right away and repack the buffer with a seventy-thirty mix of heavy castor oil and animal fat.”
He turned back to the low roof wall, casually brushing a fleck of light metal sabot dust from his lapel.
“Plus, that carcass is lying directly across our main drainage right-of-way. Toby, assemble three salvage crews with crosscut saws, block-and-tackle rigs, and hauling sledges.”
Borin slowly crawled forward on his hands and knees. He stared up at Giles in stone-hard respect. “Lord Giles... You... You wish to carve the beast?”
“Of course I wish to carve it,” Giles said. He pulled his slide rule from his vest. “That creature represents eighteen tons of high-pulling runic hard shell plates with a pulling yield strength of at least three hundred and fifty tons of pressure. Layered with rolled pig-iron plate, it will provide ideal composite armor for our future heavy-duty vehicles and heavy watercraft. And fish out its mana core. With proper copper wire wrapping, we can use it as a steady-state excitation transformer for the blast fire air blowers.”
He stepped toward the ladder-well, pausing to look back at the dwarven envoy.
“Master Borin. Your mountain clans spent two hundred years complaining that the Black Fens were an impassable barrier of rot and monsters. Now the water is draining, the fuel is pressed, the iron is flowing. The outer edge hunting beast is stopped. Are you prepared to sign the permanent stone trade compact, or must I dredge a canal through your old family mountains as well?”
Borin swallowed hard, pulling a heavy wax-sealed parchment from his tunic with trembling fingers. “I... I’ll sign, Lord Master builder. I’ll sign anything you place before me. Just... Promise me that brass needle will never be pointed at the High Spires of Karak-Drak.”
“I have zero interest in your spires, Master Borin,” Giles said deadpanly, beginning his descent down the ladder. “Their height slope is atrocious, and hauling concrete up a thirty-degree mountain slope is an office nightmare.”
Before Giles reached the ground, Toby Karr came sprinting along the lower narrow high walkway from the southern canal cut, his boots coated in gray silt. He waved his arms wildly.
“Lord Giles! Lord Giles! Look at the canal bed!”
Giles stepped onto the wooden walkway planks, raising an eyebrow. “Toby, if the dredge auger jammed on another stump, tell Caleb to reverse the paddlewheel.”
“Not a stump, Lord Baron!” Toby shouted, gasping for breath. “The auger... When the water drained from the hydra’s wallow, the silt washed away! The canal cut didn’t hit clay... It hit stone! Huge, dressed solid mountain stone forty feet wide, laid in perfect linked herringbone!”
Giles froze. His eyes sharpened.
He walked to the rim of the canal trench and looked down into the receding brown waters.
There, emerging from the thousand years of choking black fen muck, lay an ancient, spotless roadway of polished quartz-granite cut stone, stretching in an unbroken, dead-straight line toward the crags of the distant northern mountains.
A sharp, ringing chime rang in Giles’s ears, and the settlement screen flared with golden light.
Giles slowly knelt, running his fingers across the cold, ancient solid mountain stone that had lain buried since before the fall of the first empires.
A faint, dry smirk touched his lips.
“Sub-base already compacted. Proper crowning. Zero frost heave,” Giles murmured softly. “Finally... A builder who understood road grading.”
