It looks like there may be some confusion regarding the structure of Star Wars content. To clarify, the Star Wars saga is primarily presented through movies, animated series, and various expanded universe materials, rather than traditional numbered seasons like a TV series.
Originally, the main Star Wars film saga consists of three trilogies, commonly referred to as the Skywalker Saga. In addition to the films, there are animated series such as "Star Wars: The Clone Wars," "Star Wars Rebels," and more recent series like "The Mandalorian" and "Ahsoka."
As of my last knowledge update in October 2023, there isn’t a canonical structure that includes "12 seasons" of a Star Wars series. If you're referring to fan-made content, alternate timelines, or specific expanded universe works, those can certainly vary and might not align with the official storyline.
If you could provide a bit more context about what specific series or elements you are referring to, I'd be happy to discuss that further!
