Maybe an Imperial officer who is extremely cunning and ruthless. He might be obsessed with hunting down the Rebels and has a personal vendetta against them. He could use underhanded tactics and his knowledge of the Empire's resources to cause trouble for our heroes.
Well, it could be that the characters go on separate adventures that further develop their skills. Maybe Ezra discovers new Force abilities that he uses to help the Rebellion in unexpected ways. He might meet new allies or face new villains.
I'm not sure as I haven't read this novel specifically. But usually, in a series novel, there are protagonists who drive the story forward. It could be a young couple, perhaps, given the somewhat romantic - sounding title.
In a time - travel story, it could be an alternate version of Ezra himself. Maybe Ezra from a different timeline where he turned to the dark side. This dark Ezra would oppose the normal Ezra, seeing his attempts to change things as a threat to his own power and the dark future he has created.
It could be a slaver boss. This character might be someone who has a network of slaves and sees the Seventh Sister as a valuable asset. He is cruel and only interested in profit. He would constantly try to break her spirit and force her to do his bidding. Maybe he also has some knowledge of the Force that he uses to keep her in check. Also, it could be an alien warlord who enslaves the Seventh Sister to fight in his gladiatorial arenas, seeing her as a great addition to his entertainment.
I'm not sure specifically as I haven't fully studied this drama. But typically, there would be a male and a female lead who are central to the love story.
Love and friendship are likely to be main themes. In many novels, these elements play important roles in driving the plot and character development.
One common theme is love and its endurance. Since the series likely has elements of relationships, fanfictions may explore different aspects of love, like how it survives through difficult times.
In some fanfictions, there could be a powerful Sith Lord who is specifically targeting Ahsoka and Lux. This Sith Lord might see their combined potential as a threat to their own plans for galactic domination.
I'm not sure as I haven't read it. But it could be about love or fate considering the title. The'red thread' often symbolizes a connection, and'meet again' might imply a story of relationships that are meant to be.
Ezra Bridger is one of the main characters. He is a Force - sensitive boy who becomes a key part of the Rebellion. His character development from a thief to a Jedi is a major aspect of the stories.
