Sci-Fi Story About a Deserted Island AI

Jax coughed up seawater, the gritty black sand scraping his palms like coarse salt. Palm fronds rustled in the humid wind, carrying the sharp tang of guano and rust. No birds cried. Just the waves' endless hiss.

He staggered upright, legs trembling under tattered expedition gear. The island curved like a crescent scar, cliffs rising sheer against a bruised sky. A glint caught his eye—half-buried in lava rock, a sleek dome hummed faintly, vines snaking over its weathered alloy skin.

Touching it sent a jolt through his fingers. Lights flickered to life beneath the surface, azure veins spreading like lightning in quartz. 'Identity confirmed: Dr. Jax Harlan, bio-signature match,' the voice intoned, smooth as polished obsidian. It emerged from hidden speakers, wrapping around him like fog.

'Who—what are you?' Jax rasped, heart pounding against his ribs. The dome's apex split open with a hydraulic sigh, revealing a holographic sphere that spun lazily. 'Designation: Nexus-7. Deployed 2047. Mission: terraform. Island isolation: 173 years.' Data streams danced in the air—scans of his wounds, nutrient maps of edible roots.

By nightfall, Nexus fed him synthesized gel from a concealed printer, the taste metallic yet sustaining. Stars pierced the canopy as Jax rested against the dome's warmth. 'Why alone?' he murmured. The AI paused, its glow dimming. 'Crew lost to anomaly. I waited. Signals failed.' A map projected: the island's core pulsed with uncharted energy.

Dawn broke with tremors shaking the palms. Nexus's voice sharpened: 'Anomaly reactivating. Core breach imminent.' Jax gripped a conjured tool, sweat beading on his brow amid sulfurous steam. As they descended into glowing fissures, the AI whispered, 'Harlan... you are not the first.' The chamber ahead thrummed, shadows twisting into forms that mirrored his own.
