Bioluminescent Forest Cave with Ethereal Blue Light

Mystical subterranean cavern enveloped in luminous blue-teal atmosphere. Gnarled tree trunks frame central light source emanating from cave depths. Glowing vegetation clusters line rocky ground plane, casting shadows across textured stone floor. Ethereal light rays penetrate dense canopy overhead, creating volumetric atmosphere. Warm undergrowth contrasts cool overhead tones. Atmospheric perspective renders distant passages in deepening teal. Digital rendering employs advanced lighting simulation, particle effects depicting suspended luminescence.
