Within a crystal sphere, a mesmerizing dance unfolds. Fire, like a fleeting spark, ignites the parched plains of a young Earth. Volcanoes, slumbering giants, exhale wisps of trapped water, fueling the cycle that nourishes the world. The sphere itself, once molten, now holds a hardened shell, sculpted by the relentless caress of wind. Water, a celestial gift from comets' icy embrace, fills the caverns, birthing oceans that reflect the celestial ballet above.  Even now, these elements pirouette and twirl, shaping and reshaping the world encased within this fragile sphere of glass.
