Stone groaned, splitting with reports like artillery fire. Kiko stumbled, grabbing Datu by the arm as a chasm ripped open just before them, exhaling a hot, sulfurous breath. The ground bucked violently, throwing them off balance. “She’s tearing it apart!” Datu yelled over the din, his voice strained. His gaze darted from the expanding blackness of the Core to the cliff precipice. “We have to stop her, or we’ll be crushed along with this entire instance!” Kiko tracked Ida, a swirling silhouette of malice and power, her face barely visible within the black mist. She wasn’t merging; she was becoming the cataclysm. The corrosive haze wasn’t just a shield or a binding; it was part of her, an active force of disintegration. He watched a thick vein of dark vapor pulsate from the Core, slamming into a distant cliff face. The rock didn’t just split; it dissolved into ash and air, consumed by the shadow. It was outright erasure. “The way it ‘unravels’ the rock…” Kiko murmured, his brow furrowed in concentration, ignoring the frantic tremor of the ground beneath his feet. “It’s like… a reverse weave. Pulling the threads of existence apart.” Datu was already assessing escape routes, his hand going for the hilt of his twin blades. “We don’t have time for your metaphors, Kiko! We need a plan to survive, not analyze architecture!” Kiko set his footing. “It *is* the plan. If she’s unweaving the world, maybe I can… re-weave it, or at least stabilize the strands.” He squinted through the gloom. The air bristled with tension, a chaotic lattice of invisible threads vibrating with ruin. [Warning: Sanctuary Instability Critical. Spatial Distortion Imminent.] The blue text flashed in Kiko’s vision, then immediately a new line appeared, stark and urgent: [Warning: Enclave Life Support Compromised. Critical Resource Drain Detected.] Back in the safe zone, the main operations room plunged into chaos. The massive projection of the flooded archipelago flickered wildly, then went black. Klaxons shrieked across the metal ceiling. Monitors flashed crimson alerts: ‘Bio-Dome Integrity Failing,’ ‘Power Grid Instability,’ ‘Med-Supply Feed Disrupted.’ In the chill of the medical ward, Tala Alon coughed, a dry, rattling sound. The hum of her intravenous pump died. Her oxygen concentrator spluttered, its rhythm replaced by an erratic whine before going cold. A crust of frost crept across the ward’s glass pane, obscuring the view of the distant flooded archipelago. “Power cut?” Nurse Gana’s voice was sharp with alarm as she rushed past Tala’s bed, her footsteps echoing in the suddenly dim room. “Generator should have kicked in!” Tala pushed herself up on one elbow, her breath shallow. She knew this wasn’t just a power cut. Kiko’s telemetry feed, which she mirrored for observation, had gone completely dark moments ago. Her brother was trapped inside. Her fingers tapped against the worn slate Kiko had gifted her, its screen the only illumination left. “It’s not just the generator, Nurse Gana. The whole utility grid is failing. Look at the draw on the Med-Bay—it’s being siphoned. A massive drain.” Nurse Gana halted, staring at the plummeting numbers on Tala’s screen. “Siphoned? How?” Tala ignored the question, scrolling past months of logs. Kiko had always routed her his raw activity logs so she could study them. She scanned down the combat logs and supply tallies, stopping at the recurring 'unidentified draw' notices Kiko had dismissed as sensor errors. Not errors. Drains. She remembered Kiko describing the fog's properties, how it felt like a thick, knotted weave. She had pictured a physical curtain, but what if it was more? What if it was raw throughput? Her gaze locked onto a series of linked markers, a junction of power transfer that had grown exponentially over the last few hours, matching the dungeon's collapse. It was a parasitic signature disguised as atmospheric interference. Ida wasn't just using the fog; she was feeding it. The Core wasn't just expanding; it was *consuming*. “The blight… it’s a circuit,” Tala murmured, her nose inches from the display. “It doesn’t just shield; it siphons. It’s a tap pulling our base supplies directly into the Core to feed *her*.” Ida wasn’t just merging with the Core; she was leeching power siphoned straight from the settlement to rewrite reality. If the blight was a conduit, a feedback loop, then the solution wasn’t to clean the Core or unravel its output. It was to sever the connection, to cut off its fuel source. She typed furiously, shivering from the chill creeping into the ward. Her interface permissions, though limited, allowed direct pings to paired user slates. She routed a transmission straight to her brother's console, hoping it would pierce the collapsing instance. She hit the transmit key. [Message Sent: Kiko Alon] In the shuddering cavern, blue text flared in Kiko’s peripheral vision. Amidst collapsing stone and Ida’s deafening roars, a dispatch box shimmered into view. Not an alert from the construct, but a note from his sister. He read the words: [Tala Alon: It’s a feedback loop. Cut the flow, don’t just clean the stain.]
