The Force is a major part of the Star Wars universe and Ahsoka will be no different. First introduced in Star Wars: Episode IV - A New Hope, the Force is a mysterious energy field that flows through all living things. It's what gave the Jedi their power and has a Light side and a Dark side. As Star Wars lore has expanded, so too has this unique celestial power, gaining more concepts like the Living Force and the Cosmic Force. Books, comics and animation have revealed that there is much more to the Force than just the Light and Dark side, adding a level of mystery to it.
