The rust-grimed lever resisted, a stubborn beast of pitted iron. Zirra grunted, shoulder pressing into the cold metal, a bead of sweat tracing a path down her temple. Beside her, Kaddis strained, muscles coiling under his thin tunic as he wrestled with the massive barrels of cerulean resin. The humid air of the central waterworks, usually pristine and cool, now smelled faintly of damp rock and the sweet, earthy tang of their potent concoction.
“A bit more oomph, husband dear?” Zirra teased, her voice a low murmur against the steady rush of water through unseen conduits. “Or is all that farm strength reserved for, ah, more delicate applications?”
Kaddis didn’t even glance her way, teeth set hard. “If you’d stop flirting and actually *help* with the weight, we’d be done already.” He shoved a barrel forward an inch, the squeal of its wooden runners reverberating off the stone vaults.
They had chosen the deepest hour of night, when the few sentries stationed here were rumored to prefer illicit shisha pipes to their patrols. Zirra scanned the shadowed archways, tracking the heavy pulse of the main sluice intake ahead of them. This was the heart of the Vash dominion, the very arteries that fed their wealth. To foul it would be an act of desecration beyond imagining.
A cough broke the silence from a high alcove. Kaddis froze, his head snapping up. Zirra’s hand drifted to the concealed blade at her hip. Two hulking figures in the drab livery of the high-tier watch emerged, their lanterns casting long, distorted shadows across the ceiling. They hadn’t expected wardens this deep inside.
“Well, well,” one rumbled, a thick, braided whip hanging from his belt. “What have we here? Little midnight gardeners?”
The second warden squinted, his gaze falling on the barrels. “What’s in those? Looks like... blue mud.”
Kaddis didn’t wait. With a roar that vibrated through the stones, he kicked the nearest barrel over. A cloud of fine, grey dust exploded into the air, swirling like an angry spirit. It wasn’t the resin. It was the desiccated remains of the fertilizer he’d used on his own blighted fields, a powder Zirra knew was infused with the caustic minerals of the lowlands, designed to deter burrowing pests. In the enclosed space, it was blinding.
Both men cried out, knuckles grinding into their eyes. “What in the—my eyes!”
Kaddis moved with a speed Zirra hadn’t known he possessed. He was a blur of motion, using the barrels as cover, kicking out with precise, brutal efficiency. The first man crumpled, air barking from his lungs as Kaddis’s heel drove into his sternum. The second stumbled back, temporarily disoriented, allowing Kaddis to slam a barrel into his midsection with a sickening thud. The man slid to the stone, wheezing through cracked lips.
Zirra watched, cold calculation briefly yielding to sharp interest. This was the Kaddis she’d glimpsed, fierce and protective, stripped of his despair. He had stopped acting like kindling and started acting like iron. He turned back to her, dust streaking his collar, gaze fierce and steady.
“The gate. Now,” he bit out, his voice hoarse.
They reached the main sluice works, a monstrous assembly of gears and chains designed to regulate the flow to the upper tiers. It was built with a locking pin, meant to prevent tampering. Zirra fumbled at it, her fingers slick with grime.
“It’s too thick,” she said, pulling at the heavy, reinforced pin. “This thing is meant to keep the flow to a trickle, not a torrent.”
“We need maximum pressure,” Kaddis urged, glancing back at the stunned wardens. “Enough to flood the conduits.”
Zirra’s gaze fell on the main cogwheel, its teeth gleaming dully in the dim light. It needed to be jammed open, permanently, beyond all regulation. She thought of the Vash estate, the shimmering botanical gardens her half-sister Taphath now paraded through, oblivious. She thought of her mother, of the brief, stolen moments of warmth in a life of cold calculations.
Her hand went to her neck, closing around the smooth, cool gold of her pendant. It was solid gold, etched with a single, delicate blossom—the last thing her mother had given her. Her only keepsake, a tangible link to a past she rarely allowed herself to acknowledge. It was a stupid, sentimental thing, a weakness. And now, it was a weapon.
Zirra unhooked the clasp. The disk sat heavy in her palm, a bright chip of gold against the grimy masonry. She looked at Kaddis, a silent question passing between them. He nodded once, grim and ready. This was it. No turning back.
She wedged the golden trinket deep between the teeth, ramming it home with her heel until the soft metal buckled and seized the iron cogs. A groan ripped through the waterworks as the sluice gate shrieked, grinding open past its intended stop. Water roared, a deafening cascade, shaking the very foundations of the structure. The pressure intensified, a thrumming vibration through the stone under their feet.
Through the spillway grates, the deep blue resin plunged into the main conduit, carried down the vertical chutes toward the lower city. It shimmered like spilled ink under the moonlight, rushing down towards the lower terraces.
The back-siphon groaned into life, dragging gallons of brine and raw counter-resin upward through the irrigation flues toward the Vash estate. By dawn, Taphath's pristine hybrid shrubs would rot in alkaline silt.
A sharp, metallic crack echoed through the chamber, making them both flinch. The scrap of crushed gold had held only moments, but the teeth had sheared clean through their track. The pressure valve, pushed beyond its limits, groaned one last, tortured protest. A violent shudder ran through the stonework, and with a deafening crack of warped iron, the axle assembly tore itself apart. A geyser of water erupted, slamming into Kaddis. The spray swept Kaddis clean over the parapet before he could set his footing, the rush of falling water swallowing his shout. Zirra lunged to the coping and peered down into the spray: forty paces down, Kaddis swung by one white-knuckled fist from an intake strut, the abyss roaring beneath his boots.
