Neon Artifact in Cyberpunk Underground Tunnels

A relic artifact nestled in the damp, rusted floor of sprawling cyberpunk underground tunnels. Bioluminescent graffiti glows along corroded metal walls; neon cables drape from ceilings; steam vents hiss; puddles reflect cyan, magenta, and teal neon. The artifact is a crystalline device with alien glyphs and a pulsating core, partially encased in cracked glass and tangled circuitry. Surrounding this scene, maintenance drones drift past, rain slick surfaces, and shadowy figures in hooded coats emerge from the darkness. Tunnel walls are lined with riveted iron, grime, and phosphorescent moss. The composition blends gritty realism with neon-fueled futurism. Dramatic lighting, ultra-detailed macro on the artifact, with a deep tunnel perspective, vanishing point, lens flares, and subtle film grain.
