A sprawling cave system where the walls are made of glowing, translucent stone, their surfaces catching the light from the rivers of molten crystal that flow through the caverns. The cave floor is covered in thick, glowing moss that pulses softly in shades of blue and green. Massive, glowing stalactites hang from the ceiling, their surfaces smooth and reflective, casting long, sharp shadows across the cavern floor. 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.
