Paint a picture of the celestial city, a beautiful, futuristic metropolis built on the clouds. its tall, silver spires reach towards the heavens, and its streets are filled with magical, flying vehicles. the city is home to all manner of mythical creatures, from winged unicorns to fire-breathing dragons. the air is alive with the sound of music and laughter, as the citizens go about their days in this utopian paradise. in the distance, a huge, rainbow-colored bridge stretches across the sky, connecting the celestial city to other magical realms beyond.
