There are fanfictions that expand on the backstories of minor characters. In some, we might learn more about the life of a random sellsword in Essos before he came to Westeros. Also, fanfics often delve into the magical aspects. They could show how the magic in the world of 'A Game of Thrones' could be used in different ways, like a new form of dragon - related magic.
One interesting fanfiction could be those that explore alternative endings for characters. For example, a fanfic might give a different fate to Ned Stark, perhaps he manages to outwit his enemies and survive. Another type could be fanfics that focus on relationships not fully explored in the original, like a more in - depth look at the friendship between Arya and Gendry.
Fanfiction allows fans to express their creativity. It gives them a chance to write about their favorite characters in new situations.
One idea could be exploring what would happen if a minor character like Gendry had been secretly trained in magic. He could use his newfound powers to unite the smallfolk against the warring nobles. Another plot could revolve around a female knight from the North who disguises herself as a man to fight in the wars, and along the way, she discovers secrets about the White Walkers that no one else knows. Or perhaps a fanfiction where Daenerys and Sansa form an alliance much earlier and together they reshape the power dynamics of Westeros.
One interesting concept is alternate endings. For example, some fanfictions might have Jon Snow actually ruling Westeros in a more peaceful way than in the original series. Another concept could be character crossovers, like if a character from another fantasy world entered the Game of Thrones universe. It adds a whole new layer of intrigue.
One idea could be exploring what would happen if a minor character, like Gendry, had a more prominent role in the story. He could potentially become a powerful lord and change the political landscape.
One interesting aspect is the exploration of different character backstories. Fanfiction often delves deeper into the pasts of characters like Jon Snow or Daenerys Targaryen, giving new perspectives. Another aspect is the creation of alternate endings. Since the original series' ending was controversial, fanfiction writers come up with their own versions that might satisfy different fans. Also, it allows for unique character interactions that didn't occur in the show or books, such as pairing characters from different houses in unexpected ways.
A great idea for 'Game of Thrones fanfiction' is to rewrite the story from the perspective of the smallfolk. For instance, how did they really feel during all the wars and power struggles? How did the common people in King's Landing cope with the different rulers? You could also explore a fanfiction where the White Walkers are not the villains. What if there was a misunderstanding and they were actually trying to protect the realm from some other greater threat?
Some fanfictions focus on the backstories of minor characters. For example, a story about the life of a Night's Watch member before he joined. It could explore his reasons for joining, his family, and how he coped with the harsh life at the Wall. There are also fanfictions that rewrite the end of the series in a more satisfactory way for fans, like Jon Snow actually ruling the Seven Kingdoms in a more just and prosperous manner.
There are fanfictions that imagine a world where the White Walkers and the humans form an alliance. For example, they might work together against a greater threat from Essos. Some fanfictions also explore romantic relationships that were only hinted at in the original series, such as a more in - depth look at the relationship between Brienne and Jaime. Additionally, there are stories that rewrite major battles from different perspectives, like the Battle of the Bastards, showing how different decisions could have led to different outcomes.
One idea could be exploring what would happen if Jon Snow was raised by the Starks as a trueborn son. Another could be a fanfiction about Daenerys Targaryen's journey if she had made different alliances earlier. Or perhaps a story about Arya Stark training with a different master assassin.
One interesting 'asoiaf crossover fanfiction' could be a crossover with the Lord of the Rings universe. Picture Jon Snow in Middle - earth, facing the orcs. Another could be a crossover with the Harry Potter world, like Daenerys Targaryen using magic in Hogwarts. And there might be one where Arya Stark travels to a different fantasy realm and uses her assassin skills there.
