Valeska stared at Nikodem, the remnants of the Murk still clinging to the air like burnt sugar. His grip on her arm tightened, his fingers digging into the muscle. The grand salon, minutes ago a glittering stage for Ostrachova’s elite, now smelled of scorched ozone and fear. Marika’s shrieks about the ruined voltaic grid were a distant, irritating buzz. “What do you mean, ‘feeds them’?” Valeska demanded, her voice low, dangerous, a direct counterpoint to his barely contained panic. She pulled her arm free, rubbing the ache. His eyes, usually cool and calculating, darted around the cavernous room, seeing dangers she couldn’t. He truly looked terrified. “The power… it’s not clean,” he whispered, leaning closer, his breath hot against her ear. “It draws them. I thought I could control it, channel it, but it’s too strong. The grid isn’t just light, Valeska. It’s… a beacon.” He swallowed hard, his gaze falling to the splintered floorboards where the Murk had dissipated. “Marika… she knew. She told me it was a necessary sacrifice for progress.” Valeska pushed away, the disgust a bitter taste. Marika’s twisted logic had always sickened her. To knowingly fuel the Murk, to risk an entire city for an empire built on the dark… it was monstrous. She glanced up at the maintenance gallery, a flash of movement against the upper rafters vanishing before she could track it. Casimir. He had seen it too, perhaps understood it. Nikodem’s words suddenly made chilling sense of the Murk’s sudden appearance. It wasn’t just Olek drawing them; it was Nikodem’s tech actively inviting them. “You have to stop it,” Valeska said, her voice a clipped command. “Shut down the grid.” Nikodem shook his head, a desperate tremor. “I can’t. It’s too vast. And Marika… she won’t let me. She sees power, not peril.” Before Valeska could press him further, a hand clamped down on her shoulder, pulling her away. Casimir, his face unreadable, stood beside her. His touch was firm, possessive, a silent claim. He hadn’t spoken a word since the Murk’s dispersal, but his presence was a heavy anchor in the swirling chaos. He gave Nikodem a long, piercing look, then tugged Valeska towards a discreet service exit. “We’re done here,” he rumbled, his voice like grinding stone. Back in the Drowned Wards, the air was thick with the usual humidity and the metallic tang of the under-canals. The reek of brine and refuse was a familiar comfort after the perfumed hypocrisy of the spires. Casimir’s workshop, deep beneath the Rotting Rook tavern, hummed with a low, mechanical thrum. Olek, thankfully, was asleep in a cot in a corner, a small, prototype lens resting on his chest, its faint shimmer a steadying pulse against the encroaching dread of the Long Eclipse. The newly acquired quartz, hundreds of raw, crystalline chunks, lay stacked in crates along the workshop’s flooded edges. Each piece was precious, a lifeline for Olek, for the entire Drowned Wards. Valeska ran a hand over a particularly jagged specimen, its surface cool and unyielding. They had to start cutting, polishing, aligning. Soon. A sudden crash from the main access tunnel ripped through the relative quiet. The muffled shouts and the splintering sound of wood against metal were unmistakable. An attack. Valeska’s hand went instantly to the heavy wrench she kept tucked into her belt, her posture shifting from engineer to fighter. Casimir, already moving, grabbed a length of reinforced pipe, its end jagged with twisted rebar. His eyes, usually calm, now held a glint of predatory focus. “Down here,” he commanded, gesturing towards the deeper levels, a series of flooded basements accessible by precarious iron rungs set into the masonry. “The quartz is more secure.” They scrambled down, the cold, murky water splashing around their ankles. The air grew heavy, the usual stench of the canals mixing with the coppery tang of fresh blood. The workshop’s main floor was still bright, but down here, only a few sputtering lantern-lenses cast long, dancing silhouettes. Valeska could hear the invaders above, their heavy boots sloshing through the water, their curses echoing off the stone. They were looking for something, or someone. “The Grims,” Casimir murmured, his voice tight. “Marika’s coin at work.” The Grims were a particularly vicious outfit from the western districts, known for their brutality and their habit of gutting their targets before stealing their coin. The first of them appeared, a hulking brute with a scarred face, dropping down the rungs. He wore a heavy, stained duster and carried a rusted machete. He barely registered Valeska before she moved. Her wrench whistled through the air, catching him just below the jaw. The sound was sickening, a wet crunch. He toppled backward, splashing into the murky water, his machete clattering away. Two more followed, smaller but quicker. Valeska met the first with a kick to the knee, twisting his leg at an unnatural angle, before slamming her elbow into his temple as he cried out. Casimir, meanwhile, was a whirlwind of controlled violence. He didn’t just swing the pipe; he used the mirrored surfaces of the abandoned machinery, the slick, reflective water itself. He’d feint, catching an attacker’s line of sight, then use a sudden, blinding flash from a carefully angled pane of glass to disorient them. His strikes were precise, efficient, targeting joints and pressure points with bone-shattering force. A Grim staggered, clutching his eyes, and Casimir’s pipe connected with his temple, sending him sprawling into the water. Valeska fought with a savage grace, her movements fluid and economical, honed by years of surviving the under-canals. She moved through the water, using its resistance to add weight to her blows. A short, wiry Grim tried to flank her, but she spun, catching his arm, twisting it until she heard a satisfying snap. He screamed, dropping a wicked, barbed knife. She didn’t hesitate, plunging it into his thigh. He gurgled, collapsing into the water, already bleeding out. “Boss is down here!” a voice bellowed from above. “The Widow’s Claw sent us! Find the rock, destroy it!” Valeska and Casimir moved back-to-back, breathing hard, the rhythm of their blows a grim symphony. Water sloshed around them, stained crimson. The air grew thick with the smell of blood and exertion. Another Grim, larger than the others, leaped from the drop-point, a poisoned shiv glinting in his hand. His eyes, narrowed with malice, were fixed on Valeska. He lunged, aiming for her gut. She saw it, the flicker of dark liquid on the blade, the speed of his attack. There was no time to fully evade. She braced, ready to twist, to take it in a non-fatal spot. But Casimir was faster. He shifted, a blur of motion, placing himself between her and the blade. The shiv sank deep into his side with a sickening *thunk*. A gasp tore from his lips, but he didn’t fall. His pipe swung in a wide arc, catching the Grim chief in the head. The man went down, his eyes rolling back, but he was still conscious, twitching. Valeska felt a searing wave of fury. “Casimir!” She spun, her hands finding the wound, already weeping dark blood. “You fool!” He gritted his teeth, his face pale. “Less talk, more finishing,” he rasped, his gaze fixed on the downed man. His eyes met hers, a silent, unwavering promise. He had taken the blow without a second thought. Her anger sharpened into deadly purpose. She kicked the Grim chief onto his back, pressing her heavy boot onto his throat. The water sloshed around his head. “Who sent you? What rock?” she demanded, her voice a low growl. The man choked, struggling for breath, skin graying against the slick stone. “The Widow’s Claw… Marika… she said… the new light-rock… it threatened their… their power,” he gurgled, blood trickling from his lips. “Nikodem’s grid… it needs… the essence… of the shadow… to run. She said the rock would… purify the air… stop the feeding… ruin everything…” Marika. It was worse than Valeska had imagined. Nikodem’s grid wasn’t just attracting the Murk; it was *feeding* on them, siphoning their essence to sustain its power. And Marika was protecting that horrifying secret, even if it meant slaughtering everyone in the Drowned Wards to do it. A small, shuffling sound drew Valeska’s attention. Olek stood at the lip of the ceiling hatch, dark eyes unblinking, his small hands clutching a tattered toy. He must have woken from the commotion. His face was pale, his dark hair falling over his forehead, and a faint, almost imperceptible shimmer pulsed around him, making the air crackle with a cold energy. The Grim chief, still pinned beneath Valeska’s boot, saw Olek. A flicker of fear, then something else, something cold and ancient, entered his eyes. He began to thrash, a desperate, animalistic struggle. The lantern-lenses around them flickered, casting erratic shadows. From the darkest corner of the basement, where the water was deepest and the light could not reach, a form began to coalesce. It was amorphous, a churning void, tendrils of inky blackness reaching out. Not a full Murk entity, not yet, but a swirling mass of dark essence, drawn by the blood, the raw fury, and the sudden quiet in the chamber. It moved, slow at first, then with increasing speed, directly towards the pinned mercenary. The man shrieked, a sound abruptly cut short as the inky mass enveloped him. He thrashed, his body contorting, then fell utterly still. The shadow-mass pulsed once, distended, then slowly, sickeningly, began to shrink, pulling the man’s form inwards, dissolving him into nothingness. When it dispersed, only a few stray bubbles rose to the surface, and the water was still, save for the remaining crimson stains. Valeska stared, her heart a cold, hard knot in her chest. Olek, her quiet, sickly brother, had watched it happen. And the Murk… it had listened to him. It had answered his presence. It had devoured the fallen mercenary, right before her eyes. The knot in her gut tightened as the truth set in: Olek had not simply summoned the entity through sickness; it had obeyed his unspoken shift in focus, purging the threat at his feet.
