The echo crystal undercroft

Generated from: A vast underground cathedral cavern deep beneath a floating world, enormous stalactites of pure teal crystal hanging from a ceiling hundreds of metres overhead, each one glowing like a chandelier, casting cool blue-teal light onto an ancient stone floor far below carved with circular map-like reliefs. A tiny explorer figure stands on the floor, dwarfed by the scale. The cavern opens at the far end to a vertical shaft of warm golden sky light from above. No floating islands, no sky horizon, entirely subterranean. Cinematic 3D game environment, wide establishing shot looking up into the crystal ceiling, awe and wonder, no text, no UI.
