With the final trailer for Star Wars: The Rise of Skywalker now out, the question of how the Skywalker Saga will end is once again on the minds of fans. And the concept of balance in the Force is in the air again too, as it seems like a way J.J. Abrams and his team could choose to close things out. It is, after all, something that the series has seemingly been building towards since the Original Trilogy.
In a mythology full of mystery and ambiguity, one of the central themes in Star Wars revolves around the notion of bringing balance to the Force. The Force, as we know from Obi-Wan Kenobi’s initial conversation with Luke Skywalker in the Jedi Master’s hut on Tatooine, is “an energy field created by all living things. It surrounds us, penetrates us; binds the galaxy together.” Notice Kenobi says the Force is created by all living things and seems to indicate that everything works together. He does not mention good and evil.
