Prompt (original, unmodified)
A colossal underground civilization hidden beneath the surface of the world, illuminated entirely by massive bioluminescent rivers glowing blue, teal, and emerald through endless caverns. The cinematic shot begins high above a gigantic abyss as the camera slowly descends through floating mist and enormous cavern pillars toward the hidden city below. Ancient structures carved directly into black stone cliffs emerge from darkness: towering temples, suspended bridges, glowing terraces, vertical districts built into cave walls, luminous waterfalls flowing into radiant underground rivers. The rivers pulse with organic bioluminescent light, reflecting across wet obsidian surfaces and illuminating gigantic stalactites overhead like a subterranean night sky. Tiny silhouettes of travelers move along elevated stone pathways carrying lanterns made from glowing crystal organisms. Massive floating creatures drift silently through the cavern air near the ceiling, barely visible through the fog. The camera glides smoothly above the glowing river currents and passes through the heart of the civilization where gigantic circular structures rotate slowly around the central luminous source. Environmental motion everywhere: drifting spores, floating ash-like particles, rippling reflections, glowing insects, distant waterfalls, steam vents, hanging vegetation reacting to underground wind currents. Midway through the shot, the camera reveals the true scale of the cavern: entire mountains suspended underground, endless darkness beyond the visible city, ancient ruins disappearing into the abyss. Final moments: the camera pushes toward a colossal sacred gate embedded into the cavern wall, illuminated by ancient glowing symbols awakening one by one as the bioluminescent river intensifies beneath it. Style: ultra cinematic dark fantasy sci-fi fusion, photoreal subterranean megastructure, massive environmental scale, sacred ancient atmosphere, volumetric fog, bioluminescent lighting, wet obsidian textures, realistic water simulation, atmospheric depth, cinematic realism, awe-inspiring worldbuilding, no text, no subtitles. Audio: ONLY cinematic sound effects, no music. Deep cavern ambience, distant waterfalls, glowing river energy hum, echoing stone creaks, dripping water, subterranean wind, soft organic resonance, low-frequency environmental rumble, floating creature calls, ambient cavern echoes.
