A vast, glowing cave system where the walls are made of translucent, crystalline stone, their surfaces pulsing softly with radiant light. The cave floor is covered in a thick layer of glowing, bioluminescent fungi that cast eerie, shifting light throughout the caverns. Rivers of glowing liquid flow through the cave, casting vibrant reflections on the crystalline walls. Above, the ceiling is covered in thousands of tiny, glowing orbs that pulse in time with the rhythm of the cave, creating a surreal, pulsating atmosphere.
