Sisko’s grip clamped over Ilari's leather vambrace like an iron vise. The slab where Ilari had balanced a second prior had dissolved into amethyst powder, sifting through the vacuum below. The air tasted of ozone and pulverized minerals. Above them, the overhead arch of the core groaned, shedding crystalline flakes like a dying star. “The Keeper’s purge is accelerating,” Ilari stated over the grinding tectonic noise. Even without the Glimmering Insight, the shearing basalt and widening abyss signaled immediate collapse. Sisko spit grit onto the floor, wiping a smear of grey film from his brow. “No route through the perimeter. The outer shell fused shut.” His boots pivoted, scanning the fractured enclosure for an opening. Eino, who had been scrambling behind them, now pointed a trembling finger at a section of the wall that had not yet succumbed to the petrifying light. Nestled in a shallow recess, shielded by a web of hardened, obsidian-like veins, was a growth. It wasn't organic in the traditional sense, but vibrated with an inner, soft viridescence, a slow, hypnotic expansion and contraction. It swelled and ebbed rhythmically, an emerald node anchored against the rot. “A Heartseed,” Eino whispered, his breath whistling through cracked lips. The loose wrinkles around his eyes pulled taut, fixed on the node with wild hunger. He took a hesitant step toward it, the dust crunching under his boots. “Eino, no!” Sisko roared, grabbing the old man’s arm. “It’s suicide! The chamber is tearing itself apart. We need to find an exit. *Now*.” “There is no exit, Sisko,” Eino said, his gaze fixed on the pulsating artifact. A strange, serene smile spread across his face, one that deepened the lines around his eyes. “Not for me. Not really.” He coughed, a wet, rattling sound that brought a fleck of dark blood to his lips. “This isn’t just about my granddaughter, Sisko. It’s about what I’ve been hiding.” Ilari’s analytical mind quickly processed the implications. He had noted Eino’s declining health, the subtle stiffening of his movements, the persistent cough. His passive ability had always shown a faint, internal disruption in Eino’s ‘CONSTITUTION’ statistic, a slow degradation that defied conventional healing. But the full picture hadn’t been clear. “What are you saying?” Sisko demanded, stepping closer. The floor snapped beneath their heels, opening a trench lined with raw purplish fire. “Years ago, in the Whisperwind Ascent,” Eino confessed, gaze glued to the node, “an Aberration tore my flank. Barely a nick. But calcification set in. It’s why I took service with the Vanguard after my daughter left. To track down a restorative node. This is it.” His voice was raspy. “It’s been accelerating since we entered this place. I don’t have much time left.” Ilari’s mental overlay registered a frantic spike in Eino’s ‘VITALITY’ degradation rate. The petrification was indeed advancing with frightening speed, the volatile energies of the collapsing core fueling its progression. The node was Eino’s solitary cure, yet the likelihood of securing it and escaping measured close to zero. “You knew,” Sisko accused, his voice a low growl of betrayal. “And you kept it from me? From all of us?” “You would have forbade me from coming,” Eino countered softly. “And my purpose, Sisko, was not just to save my granddaughter. It was to see the Vanguard in better hands. To see you become the leader I always knew you could be. And you are, Sisko. You are.” He pulled free from Sisko's grasp, a surprising surge of strength in his withered frame. Purple luminescence flared, carving deep valleys into his weathered cheeks. He stepped toward the mineral organ. “This is my last chance.” “Eino, stop!” Ilari commanded, his analytical detachment momentarily cracking. “The wall behind that growth is already shearing. Disturbing the roots will trigger a total cave-in. You cannot harvest it safely.” But Eino wasn’t listening. His eyes were fixed on the green pulse, a beacon of hope in the heart of destruction. He broke into a stumbling run, his aging body fueled by desperation. The floor trembled violently with each stride. Sisko lunged, but the older scout had the angle. Eino leaned out with outstretched fingers as the ledge beneath the node bowed downward. Ilari’s sight spun numbers across the dust: Eino’s life expectancy dropped toward zero if his hand touched the growth, while intervening lowered the entire squad's odds to a negligible margin. [FATE-THREAD OF EINO: RAPID DEGRADATION. INTERSECTION WITH AXIS MUNDI OBJECTIVE: UNSTABLE.] [CRITICAL CHOICE: SAVE EINO (LOW SURVIVAL PROBABILITY FOR ALL) / ABANDON EINO (HIGHER SURVIVAL PROBABILITY FOR TEAM, EINO'S DEMISE CERTAIN).] Just as Eino reached the outer membrane, polished steel hummed through the air. Sisko’s axe tumbled in a flat arc, whistling past Ilari's cheek. It cleaved the root bundle with an iron ring, jarring the emerald core loose from the rock. Eino's forward weight carried him over the rim, sliding down the fault line as the shelf sheared off. The roar of the abyss smothered his shout. Sisko snapped back the axe's tether—a filament of braided wire anchored to his bracer. The taut strand snagged Eino's belt plate at the brink, halting his slide while his hands flailed for the falling core. The wrenching weight slammed Sisko against a calcified spire with a dull crack of bone. The tumbling node caromed off the stone, dropping straight into Sisko's bloodied fingers. His shoulder sagged, popped cleanly from its socket, yet his knuckles clamped shut around the emerald pulse. The entire structure around them shuddered violently, giving way with a final, deafening crack, and the ground beneath their feet began its inevitable plunge into the abyss.
