In some fanfictions, Sansa travels back to a time when she first meets Joffrey. She then uses her new - found time - traveling wisdom to avoid getting engaged to him. She could instead manipulate the situation to get betrothed to someone more favorable to her family. This would completely change the course of events, not only for herself but also for the whole Stark family and the Seven Kingdoms.
In some fanfictions, Morgan Stark travels back in time to experience different timelines. For example, she could go to a timeline where the Avengers never split up. There, she gets to see how a united team functions and learns new skills from the heroes. She might also travel to a time when her father was still alive but in a difficult situation, like during the events of Civil War, and tries to bring peace between the two factions by using her unique perspective as someone from the future.
A common plot is that Jon and Sansa travel back in time to change the events that led to the downfall of their family. They use their knowledge of the future to try and prevent tragedies. For example, they might stop Ned Stark's execution. Another popular plot is that they travel to a different time period in Westeros' history and get involved in the events there, like during the time of Aegon the Conqueror.
Time travel can make Sansa more confident. When she travels back, she has the knowledge of future events. So she can be more assertive. For example, she won't be as easily manipulated as she was before. She becomes a stronger character as she tries to change the fate of her family.
One interesting plot could be a story where Sansa manages to outwit Ramsay in a political game within the walls of Winterfell. She uses her knowledge of the castle and the people to turn Ramsay's own allies against him. Another could be a 'what if' scenario where Ramsay has a change of heart due to Sansa's unwavering strength and they form an unlikely alliance against a greater threat to the North. Maybe a plot where Sansa fakes her loyalty to Ramsay and slowly poisons his mind with false information that leads to his downfall.
Another theme is the power of knowledge. Since she has knowledge from the future, she uses it to her advantage in the past. This could be knowing about political plots or the true nature of certain characters. For instance, she could expose Littlefinger's schemes much earlier. It's about how this knowledge shapes her actions and the events in the past.
Another great one is 'Back to the Beginning: Sansa's Time Travel'. In this fanfiction, Sansa time travels and finds herself in a position to rewrite history. The author does an excellent job of weaving in the politics and relationships from the original story, making it a fascinating read with a lot of twists and turns.
Some good non - sexual fanfiction plots could involve Sansa's mental and emotional battle against Ramsay. For instance, she could use her memories of her family and her Stark heritage to resist Ramsay's attempts to break her spirit. Another plot could be that Sansa fakes her loyalty to Ramsay to gain access to information that she can use to help her friends and allies. And then there could be a plot where Sansa uses her charm and intelligence to manipulate Ramsay into making mistakes that will ultimately lead to his undoing, all while the focus is on their power struggle and not on any sexual relationship.
One plot idea could be that Jon and Sansa travel back to the time before their family's downfall. They could use their knowledge of future events to prevent Ned Stark's execution. For example, they might be able to expose Littlefinger's schemes earlier. Another idea is that they travel to a future time where the White Walkers have been defeated, but they find new threats emerging and have to figure out how to deal with them. They could also travel to different kingdoms in different eras and learn about different cultures and forms of governance, which could then help them better rule Winterfell and the North.
There are fanfictions where they go on adventures outside of Winterfell. Maybe they are on a quest to find some ancient weapon or knowledge that could help them in the fight against the White Walkers. Along the way, they learn more about each other's strengths and weaknesses, and their relationship deepens. They might face various challenges like difficult terrains, enemy attacks, and political intrigue from other kingdoms, which further cements their bond as they rely on each other to survive.
One popular storyline could be Bran going back in time to prevent the death of his father, Ned Stark. This would completely change the course of the story as Ned played a crucial role in the political drama of Westeros. Another could be Bran traveling back to the time of the First Men and learning ancient magic that he then uses to fight the White Walkers in his own time.
