The elite packguard bounded across the crusted snow in terrifying, silent exact timing.
These were the Alpha’s personal bodyguard—forty massive hunting beasts, each measuring five feet at the shoulder. Their crystal-clear azure horns swept back like frozen crowns.
Behind them surged another two hundred seasoned frostblight wolves, their bodies low to the earth, tails trailing frost.
They had seen the retention pit swallow their vanguard.
Instead of charging the ditch, they swung wide along the eastern terrace, following the cleared terrain hall toward the low wooden wall corner.
In their hungry minds, the flat snowy terrace was an open flank.
They didn’t see the twelve curved oak boxes buried flush with the clay slope, hidden beneath frosted pine branches and wind-blown powder.
They didn’t see the thin copper wire strung eighteen inches above the snow. They passed through greased brass eyelets anchored to the bedrock.
High on the narrow high walkway, Giles Croft stood beside the master disarm console.
In his hand, he held a pocket galvanometer linked to the main deep ring guide-rod.
Beside him, Kenneth Drake held his breath, his eyes fixed on the lead beast.
“They’re forty yards out,” Kenneth whispered, the words freezing on his lips.
“Thirty yards.
Twenty yards.”
The tension on the northern castle walls was thick enough to carve with a trenching knife.
Kenneth Drake’s breathing was shallow and ragged inside his woolen face-wrap, the moisture turning to frost against his gray mustache.
His hands gripped the railing so hard the spruce timber creaked.
“Thirty-five yards,” Kenneth whispered, his knuckles white.
“Lord Giles, they’re bunching up! If we wait another second—”
“Waiting is the core mechanic of shaped-charge projectiles, Kenneth,” Giles answered. His voice dropped into the soothing rhythm of a flight teacher reviewing checklist procedures.
“A premature blast at forty yards disperses the fragmentation cone across empty snow.
An engagement at twenty yards concentrates the moving payload across eighty percent of their cross-sectional area.
Patience is a weapon.
Hold.”
“Hold fire,” Giles said softly.
“Let the entire file enter the overlapping arcs.
We need maximum linear target thickness.”
Beside the master trigger console, Toby Karr watched the galvanometer needle trembling on the dial.
“Lord Giles, the needle is twitching!” Toby whispered urgently.
“The ground shaking is shaking the copper wire!”
“Electric-shock micro-tremors from the beasts’ claw impacts,” Giles replied calmly, his hand resting on the safety interlock switch.
“Notice the hum. Twelve hertz.
The elite packguard moves in a tight echelon right formation, matching pace with their sub-leaders.
Their rhythmic march rhythm creates a standing ground-shaking wave through the shale bedrock.
We don’t trigger on ground shaking.
We wait for direct crushing force.”
The lead brute, a massive scarred beast with ice fangs six inches long, lunged forward at thirty miles per hour.
Its broad, furred chest struck the taut copper wire at eighteen inches.
The tensioned wire didn’t stretch.
The counterweighted lead shear-pin snapped with a sharp PING.
The electric-shock impulse raced through the greased copper circuit at two-thirds the speed of light.
Inside all twelve Directional Shrapnel Ward-Pads, the dual mana-deep ring primer coils flashed at the same time.
THUNDERCLAP.
The sound was not an explosion.
It was the sky tearing open from horizon to horizon.
Twelve concave oak warheads blew up in a timed together. It rolled roar that drove the air out of the lungs of every defender on the wall.
A solid sheet of orange-white flame leaped from the frozen ground, instantly burning to ash the pine brush and snowdrifts.
The curved curve of the heavy oak backplates did its work with terrifying clockwork perfection.
Instead of draining away into an omnidirectional sphere, thirty-six pounds of expanding explosive gas channeled outward along a precise sixty-degree level arc.
Nine thousand six hundred chilled pig-iron pellets erupted into the freezing air at thirty-five hundred feet per second.
The speed was so huge that the pellets created a visible blast wave wall in the sub-zero air. A ripple of distorted light that scythed across the terrace eighteen inches above the ground.
Giles explained the physics of the weapon to Toby in a steady teaching tone.
“A conventional explosive charge radiates energy spherically in three hundred and sixty degrees,” Giles noted, tracing the arc with his thumb.
“Eighty percent of the blast force vents harmlessly into the sky or digs into the subsoil.
By confining thirty pounds of black powder behind a curved oak backplate heavy with forged iron straps, we create a shaped blast wave.
The expanding gas acts as a piston against the concave layer of chilled iron pellets.
It projects nine thousand six hundred active moving penetrators in a flat level fan eighteen inches above the snow.
It’s exact optimization of explosive work.”
What followed was not combat.
It was instant clockwork pulverization.
The high-thickness martensitic iron pellets, cooled in icy salt water to sixty-two Rockwell hardness, struck the charging pack like a million armor-piercing chisel points.
The crystal-clear ice armor of the wolves didn’t deflect the blow.
It shattered like window glass beneath a sledgehammer.
Flesh, bone, ice horns, and muscle were torn apart in fractions of a split second.
The lead forty brutes simply vanished, crumbled into a fine spray of crimson mist, ice crystals, and shredded fur that billowed twenty feet into the air.
The moving wave didn’t stop with the front rank.
The heavy iron bearings, carrying over four hundred foot-pounds of energy each, ripped clean through the bodies of the vanguard and tore into the massed ranks behind them.
Pine saplings along the edge of the terrace were snapped off at the stump as if mowed down by a giant scythe.
Boulders of frozen granite were pockmarked with thousands of lead-gray craters.
In zero point four seconds, over two hundred charging beasts ceased to exist as an organized fighting force.
* * *
An ear-splitting silence slammed down over the valley.
The roaring blizzard seemed to have been blown away by the sheer excess pressure of the blast.
Dense white smoke and red-tinged vapor drifted lazily across the terrace, smelling of scorched sulfur, hot iron. Then it boiled away animal fat.
Kenneth Drake stood frozen on the narrow high walkway. His mouth hanging was wide open behind his wool wrap.
His iron measuring rod slipped from his nerveless fingers, clattering against the narrow high walkway planks.
“By the Throne and the High Kings...” Kenneth whispered, his scarred face fully pale.
“The very earth rose up and fired an iron hail.”
Beside him, Toby Karr clamped his hands over his ears, his face flushed with thrilled, scared euphoria.
“The sigils exploded!” Toby shouted, deafened by the roar.
“Lord Giles, the monsters are dust!
They’re gone! They just turned into red smoke.”
Kenneth Drake crouched low behind his tall body-shield. He watched the smoke clear from the eastern terrace.
“Look at the fragmentation pattern,” Kenneth pointed out to Toby.
“It cut a level swath as clean as a scythe through summer wheat.
Nothing taller than two feet survived the blast.
The beasts behind them are running for the treeline like scalded cats.”
Down along the wall, the eighty settlers stood in stunned awe.
Where two hundred terrifying monsters had been charging a heartbeat earlier, there was now only a three-hundred-yard swath of blackened, cratered snow, littered with smoking fur and thousands of spent iron balls.
Not a single wolf in the eastern flanking column was left standing.
Giles Croft pulled his field glasses from his greatcoat, scanning the blackened kill-zone with clean, steady care.
“Fragmentation scattering conformed to test model within three point eight percent,” Giles noted. He slid his graphite pencil across his tablet.
“The curved concave backplate kept solid strength until the powder charge fully burned.
Zero back-blast damage to the wooden wall footings.”
Borin scrambled down the castle wall ladder, jogging out across the blackened terrace through the swirling sulfur mist.
He knelt in the smoking snow, picking up a spent three-quarter-inch chilled iron bearing that had punched clean through a frozen pine trunk.
He held the sphere up to the lantern light, examining its surface with his smith’s magnifying glass.
The dark martensitic skin of the iron was polished bright by moving friction. But there was not a single flat spot or dent on its outer rim.
Borin brought the pellet back to the narrow high walkway, tossing it to Kenneth with a proud grin.
“Look at that, Captain,” Borin said.
“Chilled white iron. Not a scratch on her.
She went through bone, ice, and frozen pine, and she’s ready to be melted down and cast again.
Our Lord Master builder builds weapons that pay for themselves.”
Borin the smith clambered up the castle wall ladder, covered in soot and grinning from ear to ear.
“Did you hear that roar, Lord Giles?” Borin bellowed, pumping his fist.
“Those chilled bearings chewed through them like dry biscuits!
There’s enough scrap iron out there to melt down for twenty plows!”
Giles Croft leaned over the low roof wall railing with his twenty-four-inch surveying level, checking the fragmentation radius against the field markers.
“Fragmentation thickness across Sector Three eastern terrace conformed to test model within three point eight percent,” Giles noted, writing the figures into his ledger with steady strokes.
“The two-pound counterweighted shear-pins performed with zero misfires.
Twelve out of twelve aimed units started in perfect spark exact timing.
The wooden wall timber footings absorbed less than two pounds of pressure of backup air excess pressure.
solid strength of the wall is fully uncompromised.”
Kenneth Drake slowly picked up his measuring rod. He tapped the iron metal ring against the wood to clear his head.
“We broke their back,” Kenneth said, his voice returning to its steady gravel.
“More than half the horde is dead in the ditch or blown to red mist on the terrace.”
“The horde is broken,” Giles agreed, pointing with his wooden ruler toward the center gate.
“However, the command unit remains active.
Look at the main ditch berm.”
Through the drifting smoke, a towering shape emerged from the fog.
The Frost Alpha had not charged the tripwire.
It had held back upon the granite crag. He watched its vanguard and elite bodyguard evaporate in a storm of iron.
Now, driven mad by the total destruction of its pack, the seven-foot monstrosity leaped across the retention ditch in a single, terrifying bound.
Its azure crystal-clear horns blazed with blinding blue mana fire.
Its sapphire eyes burned with pure, murderous hatred as it landed directly before the main gatehouse.
“Gate breach coming soon!” Kenneth yelled, drawing his broadsword.
“Giles, it’s hitting the timber doors.”
“Let it hit the doors,” Giles said calmly, stepping to the water gate release winch.
“Water gate Box A is primed with four tons of unhydrated burning lime powder.
Time to apply exothermic heat shock.”
