Build an enormous floating celestia...

Build an enormous floating celestial kingdom made of several interconnected sky islands. Use quartz, calcite, smooth sandstone, white concrete, gold, light blue stained glass, waterfalls, greenery, and glowing blocks. The central island should contain a huge fantasy palace with tall elegant towers, domes, arches, hanging gardens, waterfalls falling into the void, floating crystals, bridges connecting smaller islands, observatories, temples, and detailed interiors. Make the silhouette spectacular from every angle
