Flying Through Sky with Migrating Mountains

the prompt

The camera is already flying through a sky filled with living mountains slowly migrating across the atmosphere of an alien world. Entire ecosystems exist on their backs while roots of stone and crystal trail behind them through the clouds. Two flight craft weave between these moving giants, diving through valleys and tunnels carved into the mountains themselves. The camera tracks tightly as colossal peaks drift past the lens. A transparent station attached to one of the mountains overlooks the migration. The craft climb above the herd to reveal thousands of living mountains stretching across the horizon like a moving continent.
