The copper coils of the lightning-projector began to hum, a high-pitched, deafening vibration that signaled the weapon was fully charged and ready to fire, leaving the team with nowhere left to run. On the narrow granite ledge bordering the Silt-Sink, the air had ionized into a suffocating, purple-tinted haze that smelled of scorched metal and wet sulfur.

Barnaby Finch stood motionless on his eight-foot octagonal oak stilts, his broad shoulders slouched under the crushing, one-hundred-pound mass of the energy-storage core strapped to his back. He could not feel his feet. The intense electrical surge from his desperate charge-deflection had permanently burned out the nerves in his lower limbs, leaving his legs from the knees down completely cold, numb, and lifeless. He was kept upright only by the rigid timber of his stilts and the tight, double-layered oiled leather bindings that locked his boots into the wood. His left stilt-shaft, fractured near the lower bracket, groaned with a dry, splintering sound, weeping golden-amber sap under the immense load.

"Finch!" Volt-Hunter Vance’s voice boomed through his brass megaphone from the high ridge above, cold and clinical. "Drop the core! You cannot run with dead legs and a broken stilt!"

To Barnaby’s chest, young Pip clung with white-knuckled strength, his face pale and his thin arms wrapped tightly around the porter's canvas coat. "Barnaby," the boy whispered, his voice trembling against the roar of the wind. "The projector... they're aiming it right at us."

Beside them, Gideon Vance was on his knees, his shattered spectacles held together by a thin strip of rubber tape, his hands shaking as he pointed toward a dark, yawning opening in the cliff face twenty feet to their left. "The sluice!" Gideon screamed, his voice cracking with panic. "The ancient Storm-Drain Sluice! The rising floodwaters are channeling into it! It’s our only way out, Barnaby! If we stay here, that projector will vaporize the entire ledge!"

Barnaby looked toward the opening. The Storm-Drain Sluice was an ancient, pre-industrial stone channel designed to carry rainwater out of the basin. Now, half-collapsed and filled with highly charged, rushing mud, it had transformed into a roaring flume of purple clay. The water level in the basin was rising three inches every minute, spilling into the mouth of the channel with a terrifying, violent force.

"We slide," Barnaby rumbled, his voice a low, gravelly rasp that rumbled in his chest.

"Slide?" Gideon gasped, his eyes wide with terror. "On those splintered stilts? Barnaby, that’s suicide!"

"Staying here is death," Clara Thorne hissed. She was huddled against the rock face, her hands wrapped in thick, soot-stained strips of canvas, the raw, blistered skin beneath her bandages throbbing with pain. She couldn't grip her guide-staff, but her eyes held a fierce, cynical resolve. "He's right, Gideon. Move!"

Barnaby did not wait. Shifting his massive torso forward, he used his remaining core strength to swing his dead legs, steering his splintered oak stilts toward the roaring mouth of the sluice. The wood of his left stilt-shaft shrieked under the sudden shift in balance, the fracture widening as he took a heavy, agonizing step. Behind them, the lightning-projector let out a deafening crack, a blinding bolt of purple energy striking the granite ledge where they had stood a split second before, shattering the rock into a shower of hot granite shards.

Then, they fell.

The team leaped into the flooded stone sluice channel, and the world dissolved into a roaring, high-speed chaos of rushing mud and superheated steam.

Barnaby leaned his body weight back, aligning his spine with the heavy pack frame of the one-hundred-pound core to maintain his center of gravity. He executed the Static-Slick Sliding technique, allowing his resin-coated stilt-tips to glide smoothly across the wet, clay-heavy mud that filled the channel. The pre-industrial dry pine resin on his stilt-tips, designed to insulate the wood, now acted as a high-speed lubricant, allowing him to slide down the steep incline like a bobsled.

But the speed was terrifying. The sluice provided zero braking capability. If Barnaby attempted to dig his stilt-tips into the stone to slow down, the sudden resistance would trigger a catastrophic forward flip, throwing him and Pip headfirst into the rushing, highly charged mud.

"Lean back, Pip!" Barnaby roared over the deafening rush of the water. "Do not touch the stone!"

On his chest, Pip panicked as a jagged, half-collapsed section of the stone wall loomed directly ahead. Terrified, the young apprentice scout tried to dig his own short, splintered stilt stumps into the mud to brake. The sudden resistance instantly pitched their balance forward, the stilt-tips catching on a submerged rock.

Barnaby’s heart leaped into his throat. His unyielding Load-Distribution Instinct activated automatically. Clamping his massive, leather-gloved hand around Pip’s collar, he wrenched the boy back against his chest, shifting his entire hip weight to the left to counter the forward momentum. The wood of his left stilt shrieked, a violent vibration traveling up the shaft and into his numb thighs, but he managed to stabilize their descent, clearing the jagged stone wall by a fraction of an inch.

"No braking!" Barnaby rasped, his breath coming in shallow, ragged gasps. "If you dig in, the mud will swallow us whole!"

Behind them, Clara and Gideon were sliding in a tight line, their stilt-tips emitting thick trails of white friction steam as they glided down the wet clay. The scent of sweet, melted pine resin and hot copper filled the narrow channel, a suffocating perfume of high-speed survival.

Suddenly, the heavy, rhythmic thrum of steam-powered engines echoed from the concrete walkways that lined the elevated banks of the sluice.

Barnaby looked up through the purple fog. Vanguard’s rapid-response steam-cycles—heavy, rubber-treaded machines designed for wet-terrain pursuit—were roaring along the concrete banks, matching their slide speed. The riders, clad in insulated leather gear, wheeled their heavy cycles close to the edge of the channel, their searchlights cutting through the mist to illuminate the sliding team.

"Finch!" a rider shouted, raising a heavy, air-pressurized launcher. "Ground out!"

With a sharp hiss, the rider fired an iron harpoon. The heavy metal projectile trailed a thick copper wire, aiming to snag Barnaby's wooden pack frame and ground the leaking core directly into the concrete bank.

Barnaby saw the harpoon coming. He shifted his upper body, executing a sudden, high-risk sway to the right. The iron harpoon missed his shoulder by inches, embedding itself into the stone wall of the sluice with a violent spark. The copper wire snapped taut, the high-voltage feedback from the overcharged mud traveling up the cable and causing the steam-cycle to wobble dangerously on the wet concrete bank.

"Clara!" Barnaby roared. "The cycles!"

Clara Thorne did not need to be told. Reaching into her utility belt with her canvas-wrapped, blistered hands, she pulled out Brand's Rusted Revolver. The heavy iron weapon, its metal frame wrapped in thick, insulating rubber tape, felt like lead in her raw fingers. Every movement of her hands was a sickening wave of pain, the rough canvas rubbing against her open chemical burns, but her face remained locked in a grim, cynical scowl.

She rested the heavy barrel of the revolver on her left forearm to steady her aim, her fingers trembling as she pulled back the hammer. The click was swallowed by the roar of the rushing mud.

"Come on, you corporate bastards," Clara muttered, her voice tight with pain.

She aimed directly at the lead steam-cycle’s exposed boiler valve.

*Crack!*

The heavy lead bullet struck the brass regulator valve. The pressurized boiler instantly exploded in a blinding cloud of scalding steam and jagged metal shards. The lead cycle swerved violently, its rubber treads losing traction on the wet concrete, and crashed directly into the second cycle behind it. Both machines tumbled over the edge of the bank, falling into the rushing mud of the sluice with a massive, metallic splash.

The impact of the heavy metal machines into the highly charged mud triggered a catastrophic electrical overload. The mudflats of the basin were already saturated with static charge; now, the raw current from the shattered generators of the cycles surged through the water.

A massive wave of purple sparks leaped between the ancient stone walls of the sluice, crackling like a thousand breaking twigs. The air glowed with a violent, incandescent light, and the smell of ozone became so thick it burned the back of Barnaby’s throat. The electrostatic feedback traveled up his stilt-tips, the intense current causing the warped copper heat-sink on his pack frame to glow a dangerous, cherry-red heat. The faded red wool scarf wrapped around the core’s intake began to singe, releasing a thin wisp of black smoke.

Barnaby’s stilt-tips suffered severe physical wear, the rough concrete bottom of the shallow sluice grinding down the seasoned oak and scraping away the protective resin coating. He could feel the high-frequency vibration of the stone through his boots, a rapid, jarring hum that signaled their insulation was failing. If the bare wood of his stilts contacted the highly charged mud, they would ground instantly, vaporizing everyone on the pack.

"Clara!" Barnaby shouted, his voice hoarse. "The core is overheating!"

"I know!" Clara screamed back, tucking the empty revolver into her belt. Her remaining ammunition was completely depleted. "The heat-sink is warping! We have to get out of this channel!"

But there was no exit. The ancient stone walls of the sluice rose ten feet on either side, slick with wet moss and highly charged mud, offering no handholds or ledges. They were locked into the slide, hurtling down the narrow channel at a breakneck speed.

Then, the roaring sound of the rushing mud changed.

The violent, turbulent sloshing of the water was suddenly swallowed by a vast, empty silence. The heavy purple fog that had shrouded the channel for miles parted for a split second, torn away by a violent, freezing updraft.

Barnaby looked ahead, and his heart stopped.

The ancient stone sluice did not lead to a safe, low-voltage valley floor. It terminated abruptly, the stone walls ending in a jagged, fractured edge.

Directly ahead lay a sheer, five-hundred-foot drop over the bottomless, sparking rift of the Archon's Maw Chasm. The air within the chasm was so thin and ionized that massive purple sparks constantly leaped between the vertical stone walls, a silent, beautiful dome of electrical fury.

"Barnaby!" Pip screamed, burying his face in the porter's chest.

"Brace!" Barnaby roared, his voice echoing into the void as his stilt-tips flew over the edge of the stone channel, launching them into the empty air.
