The Rival's Rust

Could a runner outmaneuver a blade when every vibration of the steel traveled through the bedrock straight into her bones? Ch'aska-uay dug the heels of her hide boots into the packed gravel of the sunken terrace, feeling the answer thrum up through her calves. The unsealed lead-and-bronze canister sat heavy in the leather travel sack slung across her ribs, its unspent core humming with a dense, rhythmic heat that matched the pulse in her right radius. Ten paces across the limestone shelf, Suqta-qa stood between two hulking renegades, the serrated cleaver in his right fist catching the dull gray canyon light while his monstrously calcified left arm scraped against the rock wall with the sound of grinding pestles.

"You speak as though the high dispatchers owe you a clean road, Suqta-qa," Pachac-illa said, his voice flat and steady despite the wind whistling through the petrified boughs behind them. The veteran escort had not lowered his ironwood-and-bronze buckler by an inch. His thumb rested over the brass rim, testing the tension of the grip. "The agency gave you forty leagues of trail and a copper stipend. You spent it snorting raw wash dust behind the slag heaps."

"They gave us the rot and kept the silver," Suqta-qa snarled. The mineral plates encrusting his jaw clicked together as he spoke, shedding pale flakes of stone onto his leather tunic. "They told us the lower gorge was dead ground. They told us Inka-ri's squad died because they were weak. But here is his canister, breathing virgin silt like a newborn hearth. That core belongs to whoever has the stomach to burn it."

Ch'aska-uay did not take her eyes off Suqta-qa's boots. With every breath she drew, the refined marrow in her right forearm sang in acoustic sympathy with the canyon floor. She could feel the density of the limestone beneath them—the dense, unbroken slate where Pachac-illa stood, the brittle web of fractures beneath the left-hand renegade, and the violent, uneven weight Suqta-qa threw into his right heel to compensate for the thirty pounds of calcified armor dragging down his left shoulder.

"He is heavy on the left," Ch'aska-uay said under her breath, just loud enough for Pachac-illa to catch. "When he swings, his hip lags half a beat."

"I see it," Pachac-illa replied without turning his head. "Watch the two flanking him. Their marrow is cooked soft, but their hides are thick. Don't trade blows with dead stone. Cut where the joints still bend."

Suqta-qa did not wait for further council. With a guttural bellow that rattled the dust in the gorge, he launched himself forward. The gravel exploded under his leaden boots. He moved with terrifying, erratic velocity, the raw contamination in his veins driving his muscles past their natural limits. His serrated cleaver rose in a vicious, descending diagonal aimed straight at Ch'aska-uay's neck.

In the past, Ch'aska-uay would have relied on sheer reflex, throwing her body into a desperate roll. But now, the ground gave her the cleaver's path three paces before the steel arrived. She felt the kinetic shockwave ripple through the terrace floor as Suqta-qa planted his forward foot, telegraphing the exact angle of the blade's bite.

She did not retreat. She pivoted on the ball of her right foot, sliding inside the weapon's reach by less than two inches. The cleaver cleaved empty air with a savage hiss, the backdraft smelling of old slag and dried bile. As Suqta-qa's momentum dragged him forward, Ch'aska-uay brought her left elbow up, driving the point of the bone into the soft nerve cluster beneath his right armpit.

Suqta-qa grunted, the impact rattling his grip, but his mutated left arm lashed out in an instinctive backhand. The jagged calcified talons on his fingers swept toward her ribs like a rack of skinning hooks.

Ch'aska-uay threw her weight backward, dropping under the sweep. The talons sheared through the air where her throat had been a heartbeat before, clipping the brass buckle of her shoulder harness and gouging deep white trenches into the limestone wall behind her.

"Sloppy," Pachac-illa's dry voice cut through the clash. The old escort stepped into the gap Ch'aska-uay had created, his ironwood buckler slamming edge-first into Suqta-qa's midsection with a dull, hollow thud. "You swing that arm like a drunk carrier hauling wet timber. All weight, no balance."

The impact knocked Suqta-qa back two strides, his heavy boots skidding across the scree. But the two renegades behind him had already closed the distance.

The renegade on the left wielded a pair of crude iron adzes, his forearms coated in thick, pebbled scale that ran up into his neck. He lunged straight for Pachac-illa, chopping down with synchronized fury. Pachac-illa met the assault with seasoned precision, catching one adze on the bronze boss of his buckler and parrying the other with the flat of his broad chopping blade, the ringing clang of iron echoing off the canyon rim.

That left the second renegade to Ch'aska-uay.

He was taller than Suqta-qa, his right leg swollen to twice its normal girth by uncontrolled calcification, wrapped in filthy hemp bandages that seeped yellow fluid. He carried a heavy quarry pry-bar, swinging the six-foot length of solid iron in a wide, sweeping arc intended to smash her knees and pin her against the terrace ledge.

Through the marrow in her forearm, Ch'aska-uay tracked the iron bar's trajectory not by sight, but by the shuddering stress it exerted on the renegade's stance. The man's left leg was healthy flesh, but his right leg was rigid, unyielding stone. The joint did not absorb force; it transferred every ounce of kinetic strain directly into the terrace bedrock.

As the quarry bar whistled toward her thighs, Ch'aska-uay leaped straight upward, tucking her knees to her chest. The heavy iron bar crashed into the terrace floor beneath her feet, shattering the top layer of shale into a cloud of stinging shards.

She landed lightly on the flat of the iron bar itself, using the man's own leverage to drive the weapon into the stone. Before the renegade could wrench the bar free, Ch'aska-uay stepped forward along the shaft and drove her right heel into his groin.

The man doubled over with a breathless wheeze. As his head dipped, Ch'aska-uay closed her right hand into a fist. She did not strike with mere muscle. Channeling her internal vitality through the calcified radial bone in her forearm, she generated the same acoustic vibration she had used to part the petrified Chachacoma grove, compressing the frequency into the knuckles of her hand.

She drove the resonant blow straight into the side of the renegade's calcified knee joint.

There was no wet crunch of tearing flesh. There was a sound like a cold chisel striking frozen slate—a sharp, ringing crack that reverberated through the terrace. The high-frequency vibration shattered the brittle mineral lattice holding the renegade's knee together. The entire joint splintered into chalky white fragments and gray dust.

The renegade shrieked, collapsing instantly as his ruined leg folded sideways under his weight, the quarry bar clattering harmlessly into the scree.

"One down," Ch'aska-uay breathed, spinning on her heel to face the center of the terrace.

Her satisfaction lasted less than a second.

Suqta-qa had recovered his footing, and his eyes burned with a manic, blood-choked fury. Seeing his companion crippled on the ground, he let out an unearthly roar that sounded more like tearing slate than a human voice. The gray veins across his neck bulged, darkening to the color of wet lead as he forced a massive surge of contaminated vitality into his mutated limb. The stone talons on his left hand grew visibly thicker, jagged mineral spurs erupting through the skin along his forearm.

"You think you can run this road, girl?" Suqta-qa screamed. "I will crack your skull open and drink the marrow from your bones!"

He did not lunge at her feet this time. He hurled his entire bulk through the air, abandoning all defense, his cleaver and talons descending simultaneously in a cross-chopping maelstrom designed to obliterate everything in a five-foot radius.

Ch'aska-uay read the seismic shock of his jump through the terrace floor, but the sheer spread of the attack gave her no clean angle of evasion. The terrace was barely eight paces wide, backed by the sheer overhang and fronted by a sheer drop into the lower gorge. If she jumped back, she would tumble over the precipice; if she dove left, Suqta-qa's cleaver would catch her in midair.
