A sun-dragon was a mythical creature that would shield itself, guarding its treasures with the might of an exploding star. On hard nights, Shmi Skywalker would tell her son Anakin the story of the sun-dragon. To Shmi, Anakin was the sun-dragon. He had the strongest heart in the galaxy and it would always guide him to do what he needed, so long as he trust in it. It was a story Anakin kept extremely close to his heart and shared with very few other people. Skywalker also told Mill Alibeth of a myth from his childhood about the sun-dragon of Tatooine in order to steady her emotions. When Emperor Palpatine felt a disturbance in the Force and attempted to learn the source—the rebel Luke Skywalker—the current of the Force shielded itself much like a sun-dragon.
