The first step in writing Star Wars Visions fanfiction is to immerse yourself in the Star Wars universe. Read other Star Wars books or watch the movies and shows related to it. This will give you a better understanding of how the world works. After that, find a unique angle for your fanfiction. Maybe there's a gap in the story of Star Wars Visions that you can fill. Then, start building your story by creating a conflict. This conflict will drive the plot forward. For example, a conflict between different factions in the Star Wars Visions universe. As you write, keep in mind the unique aesthetics and concepts of Star Wars Visions.
First, you need to re - watch the Star Wars Visions series to get a good grasp of the characters, settings, and overall tone. Then, pick an aspect that interests you the most, like a character or a particular planet. Next, come up with a basic plot idea. It could be as simple as a character going on a quest. After that, start writing down your ideas, even if they seem rough at first. Don't worry too much about grammar or spelling in the beginning.
