There are several good settings for a Star Wars self - insert fanfiction. The planet Hoth, with its icy terrains, can be a great place for a survival - based story. Your character could be part of an Imperial research team that gets stranded there. Bespin, the gas giant with its floating city of Cloud City, offers a unique and visually appealing setting. You could be a smuggler making a deal there or a bounty hunter looking for a target. And the planet Mustafar, with its volcanic landscapes, can be a great place if your character has a connection to the dark side or is exploring the secrets of the Sith.
The forest moon of Endor is an excellent setting. You could be a member of the Ewok tribe, or a lost traveler who teams up with the Ewoks to fight the Empire. Tatooine is also very popular. Your character could be a moisture farmer who discovers a strange artifact in the desert and gets drawn into a much larger adventure. Also, consider the Sith homeworld of Korriban. If your character is a dark - side seeker, this could be a very interesting place to start your self - insert fanfiction.
One great setting is the planet of Naboo. It has beautiful landscapes, from the underwater Gungan cities to the grand palaces on land. Your self - insert character could be a diplomat from another world arriving on Naboo for an important summit. Another setting could be the Death Star. You could be a rebel spy trying to gather intel inside the massive battle station. And of course, the Jedi Temple on Coruscant is also a good choice. You might be a youngling starting your Jedi training there.
