Another theme is sacrifice. Since they are in a dangerous world of 'Game of Thrones', they might have to sacrifice personal desires for the greater good. Fanfictions often show how they make tough choices regarding their family and the North.
The main characters are Ned Stark and Ashara Dayne. Ned is a noble and honorable man from House Stark, known for his loyalty. Ashara is a beautiful and mysterious woman from House Dayne.
In 'Game of Thrones', Sansa is Ned's daughter. There is no sexual relationship between them in the official story as it goes against the nature of their family relationship. The show adheres to a certain moral and narrative structure.
One simple way in fanfiction could be through some kind of magic. Maybe there's a powerful red priestess who discovers Ned's body before it's fully decomposed. She uses her magic to resurrect him, much like Thoros of Myr did with Beric Dondarrion. Once back, Ned could play a major role in the political games again, this time with more knowledge and a thirst for revenge against those who wronged him and his family.
Well, in some fanfictions, Ned and Ashara could be involved in a love triangle with another character. This would add a lot of drama. For example, if there was a misunderstanding between them because of this third person, it could lead to heartbreak and tension. Also, perhaps they worked together to uncover a conspiracy in King's Landing, which put their lives at risk but also strengthened their bond.
One great Ned and Catelyn fanfiction is 'A Winter's Love'. It delves deep into their relationship before the events of the series. It shows their courtship and how they came to love each other, with beautiful descriptions of the North.
It might mean a reshuffling of loyalties and alliances. For instance, Ned could influence Renly's decisions, or Renly's actions could save Ned from certain doom. The story could take on a whole new direction.
Another fanfiction could be about Jon Snow (who is later revealed to be Ned Stark's son). In this story, he could fully embrace his Targaryen heritage much earlier. He might form an alliance with Daenerys not as an equal but as a leader, using his knowledge of the North and the loyalty of the Night's Watch to help her claim the Iron Throne in a more peaceful way.
One interesting storyline could be Ned Stark ruling justly in King's Landing. He might reform the corrupt systems in place. For example, he could ensure fair trials and end the excessive use of power by the nobles. This would likely earn him both respect and enemies among the powerful families. He could also focus on strengthening the city's defenses and improving the living conditions of the smallfolk, which would be a departure from the self - serving rule of many previous kings.
