Anakin Skywalker appears in two episodes of the Ahsoka series. He makes a surprise cameo at the end of episode 4, where Ahsoka hears his voice and turns to see him approaching in the World Between Worlds, a mystical dimension within the Force that touches every point of time and space in the Star Wars universe. In episode 5, Ahsoka has a vision of Anakin, who appears to be more than a traditional Force ghost. The reunion between the master and apprentice was a key moment in the series, as it allowed Ahsoka to learn a new lesson from her master and gain a new outlook on life.
