The sky is an ocean

A cinematic photorealistic dark-fantasy sequence high above an unknown world. The camera begins deep inside enormous blue-black storm clouds, slowly drifting forward through dense rolling vapor. Visibility is extremely limited at first. Distant thunder rumbles as faint flashes of cold white-blue lightning illuminate immense cloud formations far below.The camera gradually emerges from the clouds into an impossibly vast atmospheric opening. Far in the distance, a single colossal ancient dragon glides silently through the storm. It is initially almost impossible to distinguish from the darkness.The dragon has enormous ragged wings stretched nearly completely outward, a powerful muscular body, prominent horns and dorsal spines, large hanging claws, and a long thick serpentine tail trailing behind it.

The dragon feels ancient and overwhelmingly massive.The camera slowly advances toward the dragon from far below and behind, maintaining an enormous sense of distance and scale.Suddenly, an enormous branching lightning strike explodes across the clouds directly behind the dragon.For only a few seconds, the lightning turns the creature into a gigantic razor-sharp black silhouette, brilliantly outlining the torn edges of its wings, horns, spines, claws, and tail. The surrounding clouds flash almost white before immediately falling back into darkness.As the camera continues moving forward, something impossible gradually becomes visible above the storm:an endless upside-down ocean suspended across the entire sky.Gigantic waves roll across the ceiling of the world hundreds of miles overhead. Lightning branches through the suspended water like glowing veins beneath its surface. Tiny fragments of ancient stone ruins can be seen slowly falling upward from the clouds toward the celestial ocean.The dragon continues flying directly toward this impossible pheno
