The camera dives inside an artificial sun where a civilization with floating cities and plasma rivers lives in a hollow

Prompt

The camera dives through an opening in the surface of an artificial sun. Inside is an entire civilization built within the hollow interior. Floating cities orbit the central energy core while rivers of plasma arc between structures. Two flight craft skim along magnetic highways suspended above the blazing center. The observer stands inside a transparent chamber hanging directly over the star core. The ending pulls back to reveal the impossible scale of the civilization hidden inside the sun.
