One common theme is mentorship. Obi - Wan is often portrayed as a mentor figure to Ahsoka, much like he was to Anakin. For example, in many fanfics, he teaches her more advanced Jedi techniques or imparts wisdom about the Force.
The theme of redemption also pops up sometimes, even in Sith Obi - Wan fanfic. There may be a glimmer of hope that he could return to the light side. And of course, there's the theme of the Force. How does his new - found Sith connection to the Force change his perception and abilities? Writers often play with this idea in these fanfics.
There's the theme of trust. In a lot of Anakin and Obi - Wan fanfic, their trust in each other is either strengthened or tested. Another theme is the idea of destiny.

The setting is another key element. It could be set in the seedy underbelly of Coruscant where bounty hunters lurk in the shadows. Or it could be on some far - flung planet where Obi - Wan is hiding out. The setting can create a mood and atmosphere that enhances the overall story. For instance, a desolate, lawless planet can add to the sense of danger and isolation that Obi - Wan faces.
Another theme is loyalty. They are master and apprentice, and their loyalty to each other is often tested. In some fanfics, they face situations where they have to choose between their loyalty to the Jedi Order and to each other. This can lead to some really intense storylines.
