Destiny is a major theme as well. Fans often write about how Rhaegar's love was fated or how it defied fate. It could be that his love was part of a grander plan in the world of the story, or it could be that his love was something that was going to change the course of destiny but was ultimately thwarted. There's also the theme of self - discovery through love. Rhaegar might find out more about himself and his true desires through the experience of falling in love in these fanfictions.
Love triangles are quite common too. For example, there might be a situation where Rhaegar's love for one character conflicts with his duties or prior relationships. Also, the theme of sacrifice often appears. His love might drive him to make sacrifices, whether it's for the person he loves or for the greater good as he perceives it. And sometimes, there's the theme of prophecy intertwined with his love. Writers might play with how his love relates to the prophecies in the ASOIAF universe.
The unique pairing is one aspect. Rhaegar, a complex and tragic character from the ASOIAF universe, and Fem Jon, which is a different take on the well - known Jon Snow character, create an interesting dynamic. Their love story can explore different power dynamics, family legacies, and the whole concept of fate within the context of the fictional world.
Often, the theme of prophecy plays a role. Maybe Rhaegar believed Lyanna was part of some prophecy, which led to his actions. Also, the theme of family loyalty is big. How the Starks react to Lyanna's disappearance and how the Targaryens are involved in Rhaegar's actions are things that are frequently written about. It's all about the complex web of relationships and loyalties in this scenario.
Often, you'll see the theme of redemption. Maybe Rhaegar has some past actions that need to be redeemed, and Sansa can be the one to help him through it. Love against all odds is also a big theme. Given that they are from different story arcs in the original lore, their relationship in fanfiction is often portrayed as something that overcomes great obstacles. There's also the theme of political manipulation. How their marriage can be used by others or how they can use it to their own advantage in the complex world of Westeros politics.
