They expand the possibilities. For example, if there's a conspiracy theory about the Faceless Men having a hidden agenda that goes beyond what we see in the show or books, it makes their already mysterious order even more complex. It gives fans more to think about in terms of how they interact with the different power players in Westeros.
Many conspiracy theories in GoT fanfiction involve prophecies. By creating new interpretations of prophecies, like the Azor Ahai prophecy, fanfiction can change the way we view the characters' fates. If a conspiracy theory says that there are multiple Azor Ahais and it's all a ruse by the Red Priests to gain power, it makes the religious aspect of the lore more convoluted and interesting. It also makes the characters' quests for power and identity more complex as they may be chasing a false prophecy.
Furthermore, fanfictions can create connections between the forgotten houses and the main storylines. Maybe a forgotten house has a long - lost connection to the Targaryens or the Starks. This kind of connection can introduce new twists and turns to the overall lore. It can also inspire fans to look at the original story in a different light, making the world of Game of Thrones even more rich and complex.
One conspiracy theory in GoT fanfiction is that Littlefinger was secretly working for an even greater power than we knew. He seemed to be playing his own game, but some fanfictions suggest he was a puppet for an ancient and powerful force that wanted to reshape Westeros in a more extreme way.
The side story also adds to the lore by showing the relationships between different regions and cultures. We get to see how the Free Cities interact with Westeros in more detail, or how the Dothraki culture developed over time. This broader understanding of the world outside of the main plotlines in 'Game of Thrones' helps to build a more comprehensive and immersive lore.
Yes, there are likely many 'Game of Thrones' fanfictions about a maester conspiracy. Fanfiction writers often explore different aspects and theories within the 'Game of Thrones' universe, and the maesters are a mysterious and influential group, so it's a great topic for speculation and creative writing.
The magic and mythical elements from 'Game of Thrones' can be added to 'For Honor' in fanfiction. Dragons, for instance, could be introduced into the 'For Honor' world. A character from 'Game of Thrones' could ride a dragon and change the tide of battles in 'For Honor'. Also, the White Walkers could be an enemy that the 'For Honor' factions have to face together, uniting different characters from 'Game of Thrones' and 'For Honor' in a common fight.
These fanfictions can expand on the relationships in the series. A pregnant character might rely more on certain allies, or it could create new tensions within relationships. For example, if Peeta were to find out Katniss was pregnant, it would add a whole new layer to their complex relationship. It can also explore how the different districts might react to a pregnant hero or someone important to the resistance, which helps to further develop the lore of the districts.
It might add depth to the lore by revealing hidden aspects. For example, through ghost stories, it could show things that happened in the past that are not mentioned in the main game.
One way it can expand the lore is by delving deeper into the nature of The Stranger. In the original series, The Stranger is a rather mysterious figure. Fanfiction could explore its origins, perhaps it has a connection to an ancient civilization long forgotten in the Game of Thrones world. It could also show how The Stranger interacts with other characters in ways not shown in the show or books, adding new layers to the relationships and power dynamics within the story.
Well, a conspiracy in Harry Potter fanfic could be about Dumbledore. Some fanfictions claim he knew a lot more about Voldemort's Horcruxes long before he let on. Maybe he was waiting for the right moment to act for some secret reason, like he was testing Harry in a more extreme way than we thought. It makes for really interesting stories as it changes the way we view Dumbledore's actions throughout the series.
It can expand on existing characters. For example, by revealing new aspects of their pasts through the watch memories. This could give more depth to characters like Sanji.
