One idea could be exploring Ahsoka's immediate reaction during Order 66. Maybe she's in the middle of a mission with some clones she trusts, and suddenly they turn on her. It could show her struggle to survive while also trying to figure out what's wrong with her comrades. Another plot could involve Ahsoka finding other Jedi who managed to escape Order 66 and them teaming up to figure out how to deal with this new threat from the clones and the Sith behind it.
Well, a plot idea could be that Ahsoka is on a remote planet when Order 66 occurs. She then has to make her way back to the more civilized parts of the galaxy while being hunted by clones. Along the way, she meets some Force - sensitive beings who have no idea about the Jedi or the Sith. Ahsoka has to decide whether to train them to fight against the new order or keep them out of the conflict for their own safety.
A great plot could be Ahsoka having to face a Sith Lord who has a personal vendetta against her. This Sith Lord could be an old enemy she thought was dead. Or perhaps a plot where she is training a new group of Force - sensitive individuals in a post - Empire galaxy, and they face threats from remnants of the Imperial forces. Also, a story where she goes on a quest to find an ancient Jedi artifact that has been lost for centuries.
One idea could be exploring a mission that Ahsoka and Anakin go on where they get stranded on an unknown planet. They have to rely on each other's skills to survive and in the process, Anakin imparts some deeper Jedi wisdom to Ahsoka. Another could be a story set during the Clone Wars where they face a new and powerful Sith enemy together, forcing them to combine their fighting styles in a unique way.
A plot could involve Rex and Ahsoka getting caught in a time - travel anomaly. They end up in a different era of the Star Wars universe, like the Old Republic. There, they have to figure out how to get back while also dealing with the unique challenges and enemies of that time period. They might even meet some of their ancestors or Jedi from a long - gone era.
One plot idea could be that Ahsoka and Barriss are forced to team up on a mission to a remote planet. They initially have their differences due to past events, but as they face various challenges together, like fending off dangerous creatures and dealing with a corrupt local government, they start to understand and respect each other more. Their relationship could develop from one of distrust to a strong friendship.
Perhaps in the fanfiction, Ahsoka and Thrawn end up on a desolate planet. They have to rely on each other's knowledge - Ahsoka's Jedi wisdom and Thrawn's strategic military mind - to survive and find a way off the planet. As they do so, they begin to understand the motives behind their respective actions in the greater galactic conflict.
One plot idea could be Fives and Ahsoka teaming up to uncover a hidden Sith plot within the Jedi Order. They might start noticing strange behavior among some Jedi and use their unique skills to dig deeper.
One plot idea could be Ahsoka and Lux teaming up to uncover a hidden Sith plot within the Clone Wars. They might stumble upon a secret Sith artifact that the Separatists are trying to use to gain an upper hand.
Maybe a story where Ahsoka has a premonition about Anakin's fall to the dark side. She tries to prevent it in secret, which leads to all sorts of dangerous situations and moral dilemmas as she struggles with whether to tell the Jedi Council or handle it on her own.
A great plot could involve Ahsoka and Lux getting stranded on a strange planet. While there, they discover a hidden community that has been living in isolation for centuries. This community has a special connection to the Force that neither of them has seen before. They have to figure out how to get off the planet while also protecting this new discovery from the Empire. As they spend time there, they also learn more about each other and grow as characters.
One plot idea could be Ahsoka traveling back in time to the Clone Wars era and changing a crucial battle. This would have a huge impact on the future. For example, she might save a key Jedi, altering the course of the war and the subsequent rise of the Empire.
