Subterranean ballroom carved within a colossal geode, walls adorned with amethyst clusters and quartz pillars. Cascading crystal chandeliers illuminate the space, refracting light across polished agate dance floor. Sleek obsidian bar contrasts with raw crystal formations. Bioluminescent fungi accent dark corners, casting ethereal glow. Stalactites draped with delicate crystal chains create natural partitions. Plush velvet seating areas nestled in alcoves lined with citrine and smoky quartz. Waterfall curtain of suspended crystals forms stage backdrop. LED light strips accentuate geological strata. Mist swirls around ankles, emanating from hidden vents. Copper and rose gold accents complement earth tones. 8K, photorealistic, volumetric lighting, intricate details, masterpiece. <lora:Fluxartis 28.11A:0.6> <lora:Black illusion B:0.2> <lora:Illustration concept Variant 3A:0.3> <lora:FluxMythP0rtr4itStyle:0.8> <lora:flux_dev:1>
