Blue luminescent waterfall cascades through mystical cave chamber.

3D rendered environment depicting a major waterfall flowing from elevated rocky outcrop into still basin pool. Bioluminescent blue-white lighting dominates composition with warm ambient glow filtering through dense overhead canopy. Volumetric light rays penetrate misty atmosphere. Geological formations include columnar basalt-like structures, scattered boulders, vegetation clusters. Water surface reflects luminosity creating mirror effect. Atmospheric depth suggested through layered shadows, particle effects, directional light scattering. Secondary falls visible flanking primary cascade.
