As you might have heard, D.B. Weiss and David Benioff, showrunners of the critically acclaimed HBO fantasy series Game of Thrones, will be writing and producing a new series of Star Wars films as soon as their work on GoT has wrapped up some time around 2019. Though little is known as of right now, one thing we do know is that their Star Wars films will exist separately from the the Skywalker saga and Rian Johnson's planned trilogy.
This is exciting news because, as Game of Thrones fans may have already guessed, it opens up Star Wars to so many new possibilities. The franchise is still in a state of reconstruction, and as the Skywalker saga comes to an end, we'll see many bits and pieces from Star Wars Legends (the expansive universe made non-canon) reintroduced and reinvented into the current canon. Beloved characters from the old universe may live again and other, more vague aspects of the Star Wars universe may be developed.
The Sith, for example, have never been properly developed in the Star Wars film universe. With Weiss and Benioff at the helm, we may finally see a film that expands on the dark side of the Force in all its complexity, not just in the context of good versus evil. As longtime Star Wars fans know, there's so much more to it than that.
There are so many characters ripe for adaptation, with real depth and the potential for genuine emotional impact. One of the more obvious Sith characters being Darth Bane, who established the Sith Order's Rule of Two. His story, according to Star Wars Legends, began on the mines of Apatros. A life of abuse and hardship turned pushed him toward the dark side and he mastered it with ease. He saw the weakness that stemmed from each Sith Lord's greed and unyielding thirst for power-- flaws that would eventually lead to the Sith Order's downfall at the hands of the Jedi. Bane would turn the destruction of the Sith into the Order's greatest strength.
Then there are more complex characters, such as Darth Traya and Darth Revan who were first introduced into the franchise through the video game, Star Wars: Knights of the Old Republic and its sequel. Darth Traya in particular, proved to be one of the most complex and thought-provoking characters in the entire franchise. Her character was able to shed light on the weaknesses and strengths of both the Jedi Order and the Sith with a more philosophical approach. Her musings and speeches highlighted the fallacy of thinking in black and white.
