Some fanfictions depict the Jedi changing their views on relationships. In the official Star Wars lore, Jedi are often restricted from forming attachments. However, in fanfiction, they may change this stance and form closer bonds with other characters, which in turn could affect their use of the Force and their overall role in the galaxy.
The Jedi in fanfiction may change in terms of their training methods. They could start to incorporate new elements, perhaps influenced by different cultures or species within the Star Wars universe. This might include new forms of lightsaber combat that are more adaptable to various situations rather than the traditional forms.
