A new book tells of, according to an interview George gave in 2019, George's plans for the sequel trilogy in 2012, at the time of the sale.
>We already know from various parts of that galaxy far, far away that being cut in half wasn’t enough to stop Darth Maul, but apparently the Sith fighter would have been the main heavy of Lucas’ sequel trilogy with the aid of mechanical legs. Joining him, in theory, was Sith Lord Darth Talon, from the Dark Horse comic book Star Wars: Legacy. Lucas says “Maul eventually becomes the godfather of crime in the universe because, as the Empire falls, he takes over,” and that Talon was the Vader of the trilogy.
>Lucas says that his sequel trilogy parallels real-life events, and was to feature the late Carrie Fisher’s Princess Leia Organa as the lead, together with Mark Hamill’s Luke Skywalker and a new generation of Jedi. Lucas describes reconstruction as “harder than starting a rebellion or fighting a war,” going on to reference the Iraq War and the stormtroopers who would have essentially formed ISIS. The resulting power vacuum would have been easy for Maul to step into, but Leia would have eventually rebuilt the Republic and become the Supreme Chancellor. According to the director, “she ended up being the chosen one.”
>Hardcore fans will know that Lucas originally meant for the saga to be a tale from a fictional bible known as the “Journal of the Whills,” but we never got an explanation of the Whills in the film. Lucas says he originally would have explained more about them in the prequels, but decided not to after the poor reception over the midi-chlorians lore. Simply put, Whills are “a microscopic single-celled life-form” that have a symbiotic relationship with the midi-chlorians and who feed on the Force. They gave the command to the midi-chlorians to make Anakin, with Lucas stating he was touched by God, who in this case “happened to be one-celled animals”.
