Yes, there is. These events attract a huge number of Star Wars enthusiasts. They feature exhibitions, panels, and exclusive merchandise related to the franchise.
Well, Star Wars exists in both book and comic forms. The franchise has a rich collection of literature and graphic novels that expand the universe. Some people prefer the books for their depth, while others enjoy the visual aspect of the comics.
Star Wars initially came to the public's attention as a series of movies. The comics came later as adaptations or expansions of the movie universe. So, it wasn't a comic first.
Some Star Wars comic books are canon, but it depends on specific series and their official status within the Lucasfilm canon framework. Generally, those directly approved and integrated into the main narrative are considered canon.
