What could be the possible plotlines in a 'Game of Thrones' future fanfic?

In a 'Game of Thrones Afterlife' fanfic, the afterlife could be a place where different houses coexist in harmony or chaos. The Starks, Lannisters, and Targaryens could be engaged in a new kind of power struggle. This time, it's not about the Iron Throne but about something more ethereal, like control over the fates of the living. Their old rivalries and alliances might be re - evaluated and new relationships could form as they navigate this strange afterlife realm.

One possible plotline could be that they meet in a secret location. Maybe Rhaenys is on a mission and Jon stumbles upon her. They initially distrust each other due to the complex political situation in Westeros. But as they start to talk, they realize they have more in common than they thought. They both have a sense of justice and a desire to see the realm in a better state. This could lead to them forming an alliance and working together to face the various threats in Westeros.

One possible plotline could be the characters in the afterlife having to atone for their sins. For example, characters like Joffrey might face some sort of punishment or redemption arc in the afterlife realm. Another could be the great heroes of Westeros coming together to fight against some new threat that exists even in the afterlife. Maybe they have to stop a dark force from spreading chaos among the souls. And perhaps the Starks and Lannisters could put aside their differences and work towards a common good in this afterlife scenario.

One possible plotline could be about the new generations of avatars exploring uncharted regions of Pandora. They might discover new species and form unique bonds with them.

In a fanfic, Arya could have a more elaborate plan. She might gather evidence of Walder's treachery against House Stark first. Then, she uses her network of allies (either those she made during her travels or some remaining Stark loyalists) to isolate Walder. She could stage a public trial of sorts in the courtyard of his own castle, where she publicly accuses him and then executes him, sending a strong message to all those who wronged the Starks.

In some fanfictions, the baby could become a unifying force. Since Jon has a claim to the North and Daenerys had a claim to the Iron Throne, the baby might be seen as a rightful heir to both. It could bring an end to the long - standing feuds between the different regions of Westeros.

Maybe the plotline focuses on the cultural differences that the OC brings to Sansa's wedding. For example, if the OC is from Dorne, they might introduce new traditions such as a different style of wedding ceremony or unique wedding gifts. This could cause some intrigue and also some conflict as the Northerners are not used to such things. Also, the OC could be a healer who discovers a plot to poison Sansa during the wedding and has to race against time to save her, all while falling in love with her charm and strength.

One possible plotline could be that Robb manages to escape with a small group of his most loyal men. They then go into hiding, perhaps in the North, and start planning their revenge against the Freys and Boltons. Robb might also try to gather more allies, like the remaining Stark bannermen who are still loyal to him.

She could end up ruling over a part of Westeros. Her skills and experiences would make her a great leader.

In a fanfic where Jon goes to the future, he might be shocked by the advanced technology. He could see things like flying machines and strange devices that he has no concept of in his own time. He may struggle to adapt to the new social norms and values as well.
