Describe to me a dreamlike landscape where crystal caverns resonate with mystic echoes.
The vast expanse unfurls like an ethereal canvas, where the sky bleeds into a tapestry of blues and purples. In this surreal dreamscape, colossal crystal formations protrude from the ground, glistening under an otherworldly luminescence. As we venture deeper, the air grows denser with a mystical resonance—the crystalline echoes bounce off the cavern walls, creating harmonious murmurs that soothe the soul.
