Sun-dragon

A sun-dragon was a mythological creature, a type of dragon that supposedly existed inside the fusion furnaces that powered things such as starships and podracers. Larger versions of these creatures were rumored to live inside the hearts of stars themselves. The children of Tatooine would sometimes tell tales of these creatures.

Behind the scenes
"Inside your head, there is only fire. Around your heart, the dragon whispers that all things die. This is how it feels to be Anakin Skywalker, right now."

- Revenge of the Sith novelization narrator

The sun-dragon is mentioned in Matthew Stover's novelization of the film Star Wars: Episode III Revenge of the Sith. In the novel, Anakin Skywalker's fear of death and fear of losing his wife, Padmé Amidala is personified as a version of this dragon which whispers to him continuously that "all things die", an event precipitated when Skywalker witnessed the death of a star with Obi-Wan Kenobi. The whispering his hastened by Skywalker's visions of Amidala's death, leading him to create the persona of the Sith Lord Vader to quash the dragon, but as the voice whispers to him again, he fears the dragon has left a venomous fang behind.
