Some Star Wars fan communities on social media platforms like Facebook or Twitter also share fanfic links. You can follow official Star Wars fan pages or groups dedicated to Star Wars fanfiction. These groups often have members who are passionate about the franchise and are eager to share the great fanfics they've discovered.
Another place to check is Reddit. There are Star Wars - related subreddits where fans share and discuss their favorite fanfics. For example, r/StarWarsFanFiction might have some great recommendations. You can also ask the community for specific types of intergalactic fanfics you're interested in, like ones that involve epic space battles or the relationship between certain characters.
You can start by looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms have a vast collection of Star Wars intergalactic fanfics. AO3 often has a more organized tagging system, which makes it easier to find specific types of stories, such as those focused on a particular character or era in the Star Wars universe.
