Some fanfics delve deep into the backstories of the characters. They might explore Arya Stark's training in more detail, or what Tyrion Lannister was like as a child. These types of fanfics can give you a better understanding of the characters and their motives, which might not have been fully explored in the original series.
One interesting plotline could be the rise of a previously overlooked minor house in the fanfic's version of the Game of Thrones world. They might start an uprising against the more powerful houses due to long - held grievances. Maybe they've been exploited for resources or treated unjustly in terms of political power. Another could be the uprising of the smallfolk against the nobility as a whole. Fed up with the constant wars and hardships caused by the power struggles among the lords, they band together to demand change.
One interesting plotline could be how Karsi might have changed the power dynamics in the North. Maybe she forms an unexpected alliance with a major house, like the Starks, and together they face a new threat that was not in the original series.
There are also fanfics where a character's pregnancy is part of a prophecy. The unborn child is seen as a key figure in the future of Westeros, leading to various characters trying to either protect or harm the mother and the unborn baby. This can lead to complex power struggles and alliances within the fanfic.
