Neon Dungeons: Subterranean Cyberpunk City

Inside a vast subterranean dungeon, a sprawling cyberpunk city hums to life. Damp, jagged stone walls glow with neon advertisements and holographic billboards that float in the air. Glittering rain of digital light reflects off slick puddles on the ground. Rusted metal catwalks and mag-lev rails cross above a chasm, connecting carved rock districts and machine-lit markets tucked into niches in the cavern. Steam vents pulse with heat as drones buzz between stalactites, patrolling neon-lit alleys lined with bio-chrome storefronts. The skyline shows towering glass towers and cybernetic spires rising from the rock, with hanging gardens suspended by cables. A lone figure in a trench coat and augmented vision stands on a balcony, watching the city below while electric blues and hot pinks paint the damp stone. The atmosphere is electric, gritty, and otherworldly, blending ancient dungeon textures with futuristic cyberpunk aesthetics.
