In Star Wars fanfiction, the theme of light and darkness is often explored in many ways. For example, characters may struggle between the light side of the Force and the dark side. This can be seen in how they make moral choices. Some fanfictions might focus on a character who was once on the light side but is tempted by the power of the dark side, like Anakin Skywalker's fall in the official Star Wars story.
Often, it's portrayed through the actions of the characters. A character using the Force for selfless deeds represents the light, while those using it for selfish gain are in the dark. For instance, a fanfic might show a young Jedi trainee being taught the importance of using the Force to heal rather than harm, which is a clear light - side concept.
In this fanfiction, it could be that the Sith from Star Wars somehow make an alliance with the dark forces in Naruto's world. Konoha then has to rely on both their ninja skills and some newfound Star Wars - like technology or magic that has also been brought into their world. For example, lightsabers could be modified to be used by ninja, and the Force could be a new power source that some characters start to explore.
One idea could be to focus on a new character who gets caught in the events of 'Shroud of Darkness'. They could be a young Jedi in hiding who is drawn to the events on Malachor. This new character could interact with the main cast, adding a fresh perspective to the story.
The sense of mystery and the unknown in 'Heart of Darkness' can be translated into 'Star Wars' fanfiction. For example, unexplored regions of the galaxy in 'Star Wars' can be made to feel as foreboding as the Congo in 'Heart of Darkness'. Writers can create stories where characters journey into these unknown areas and face not just physical threats but also moral and psychological ones.
There's also 'Into the Dark Core'. In this fanfic, much like in 'Heart of Darkness', the main character embarks on a journey into an unknown and dangerous part of the galaxy. It's filled with moral dilemmas and a sense of impending doom, just like the source material. It's a really engaging read if you like exploring the darker aspects of the 'Star Wars' universe.
Perhaps a story where a group of rebels find themselves in a region filled with unnatural darkness that seems to sap their strength. They must overcome this and also deal with Imperial forces that are using the situation to their advantage. In this fanfiction, it could show how they use their wits and the Force to survive and fight back. This would add a new layer of danger and mystery to the Star Wars universe we know.
A fallen Jedi who wants to return to the light side could be the main character. He might have been corrupted by the dark side but now is struggling to break free. His journey of self - discovery and redemption could be the focus of the story.
One possibility is that it's centered around a young Force - sensitive individual who was kidnapped or indoctrinated by the dark side. This person then manages to escape the clutches of the Sith or other dark entities. Along the way, they might meet various characters who help them, like a wise old Jedi in hiding or a group of smugglers with a heart of gold. As they journey, they gradually learn to use the Force for good and are thus 'freed from darkness'.
Another character could be Kylo Ren. His internal conflict between the light and the dark is a rich area for exploration in fanfiction with the 'Shadows and Darkness' theme. Fanfic writers might focus on his early days of being seduced by the dark side, the shadows in his mind that led him to make certain choices.
