The discovery of Anakin on Tatooine was a big part of his back story. It set in motion a series of events that shaped the galaxy. His time in hiding on Tatooine later was also significant as it was related to protecting Luke Skywalker and the future of the Jedi. Moreover, his growth as a Jedi, learning the ways of the Force and using it in battles, all these elements contribute to the important aspects of his back story.
His relationship with Anakin Skywalker, from being his master to facing him as a Sith, is a crucial aspect. Also, his role in the Clone Wars can't be ignored.
Obi - Wan Kenobi was a Jedi Knight. He was trained by Qui - Gon Jinn. He played a crucial role in the Clone Wars. He was also the mentor of Anakin Skywalker.
The most important character is Obi - Wan Kenobi himself. He is the central figure, a Jedi Master in hiding. Darth Vader is also crucial as his former apprentice and now his enemy. The Inquisitors play significant roles as they are the ones hunting Obi - Wan. And of course, young Luke Skywalker, though he's more in the background being protected by Obi - Wan.
His death is portrayed as a heroic and selfless act. He gives his life for the greater good, which is very much in line with the Jedi code.
The 'obi wan kenobi novel' is all about Obi - Wan Kenobi. It likely tells of his journey, his growth as a character. Maybe it starts with his situation post - Order 66, how he has to adapt to being alone and hunted. It might also introduce new characters that cross his path and how they influence his decisions. It could describe his training and how he passes on his Jedi knowledge in a very subtle way. His battles, not just the physical ones but also the mental and moral ones, are probably a big part of the novel as well.
One possible consequence is that he could disrupt the timeline. His actions in the past could have unforeseen effects on the future. For instance, if he changes a small event, it could lead to a completely different chain of events.
If Obi - Wan Kenobi goes back in time in fanfiction, he could change his relationships. He might be more open and honest with Anakin from the start, sharing his own doubts and fears. This could create a stronger bond between them. Also, he could use his knowledge of the future to influence other Jedi. He could warn them about the impending doom of the Order, and together they could come up with a plan to counter the Sith's machinations. This would require him to convince the Jedi Council, which might be a difficult task given their traditional ways, but his knowledge of the future could give him the edge he needs.
One key element is his Force - sensitivity from birth. Another is Qui - Gon Jinn's discovery and mentorship. Also, his entry into the Jedi Order.
One key event was his training under Qui - Gon Jinn. Another was his taking on Anakin as his apprentice. And of course, the battle with Anakin on Mustafar.
One unique aspect is exploring their relationship in different time periods. For example, some fanfictions focus on their time as younglings, showing a more innocent and budding friendship. Another aspect is the 'what if' scenarios. Like what if Anakin was never tempted by the dark side? Fanfictions can really dig into that. Also, the way their characters can be developed further. We can see more of their internal thoughts and feelings that might not have been fully explored in the movies.
Jon Snow could be one. He has a sense of honor and leadership, much like Obi - Wan. They could bond over their shared values and Jon could learn from Obi - Wan's wisdom. Another could be Daenerys Targaryen. She is on a quest for power and Obi - Wan might see her as someone who needs guidance to use her power responsibly.
