Create an image of a mystical floating city in the sky, powered by futuristic technology and surrounded by swirling galaxies and celestial beings, blending elements of science fiction with surreal artistry.

Depict a mystical city suspended in the sky, a beacon of futuristic technological marvel. Airships and giant skyscrapers maintain a levitating presence against gravity. Sparkling solar arrays and kinetic energy generators display the advanced energy sources. The sky around the city swirls with galaxies in hues of purples, blues, and greens, as if space-time itself is being bent. Celestial beings, ethereal and translucent, weave between the stars and city structures, adding a surrealistic touch to the scene. The artwork should blend elements of science fiction, surrealism and futurism without referencing a specific artist or movement post-1912.
