In some side stories, we get to know more about the wildlings. For example, their unique culture, like how they choose their leaders and their survival tactics in the harsh North. It gives a deeper understanding of the complex world of Game of Thrones beyond the main storyline. They are not just the 'barbarians' as some in the Seven Kingdoms might think.
One interesting plotline could be the backstory of the Faceless Men in the side stories. Their mysterious origin and their training methods are really fascinating.
The side stories often explore the history of the Targaryens before they came to Westeros. We learn about their dragon - riding traditions, the Valyrian Freehold, and the events that led to their downfall in Valyria. This knowledge enriches our understanding of the power - hungry family that plays such a crucial role in the main series.
One interesting plotline could be Harry using his magic skills in the world of Westeros. For example, he might use spells to defend against the White Walkers. Another could be his interactions with the different houses, like forming an alliance with House Stark through his friendship with Jon Snow.
One interesting plotline could be a different ending for some of the main characters. For example, instead of Jon Snow going to the Wall again, he could become the king of the Seven Kingdoms. Another plotline might involve Daenerys not going mad and ruling Westeros in a more benevolent way. There could also be fanfictions where Arya Stark uses her skills in a completely new adventure, perhaps exploring new lands beyond Westeros.
Another plotline might involve reincarnation as a wildling. The character then tries to unite the wildlings in a more organized way, using their knowledge of military tactics from the modern world. They could form alliances with some of the northern houses, changing the whole dynamic of the conflict between the Night's Watch and the wildlings.
One interesting plotline could be the different fates of the Stark children. For example, in some fanfictions, Sansa might use her new - found political acumen to completely reshape the North, not just as a lady but as a true leader, making alliances that were never seen in the original series. Another could be about Daenerys. Maybe in a fanfic, she lands in Westeros and instead of immediately going for the Iron Throne, she focuses on building strong relationships with the common folk first, which changes the entire power dynamic in the Seven Kingdoms.
One interesting plotline could be a Kingsguard member having to choose between loyalty to a tyrannical king and protecting the innocent. For example, if the king orders unjust executions, the Kingsguard might struggle with their oath.
One interesting plotline could be them ruling Winterfell together. Jon as the military leader and Sansa handling the political aspects. It gives a different perspective on how the North could be governed.
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.
One interesting plotline could be a modern-day retelling where the political intrigue of Westeros plays out in a corporate setting. Characters might battle for control of a powerful company instead of the Iron Throne. For example, Jon Snow could be a young, idealistic employee trying to expose the corrupt practices of his superiors, much like the power struggles 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 an omega character rising to power in the midst of the chaotic power struggles of Westeros. Maybe an omega, who is often underestimated, uses their wits and unique abilities to influence the major players in the game.
