Survival could be a possible motive. The world of 'Game of Thrones' is full of threats. Maesters might conspire to ensure their own survival in the face of potential threats like the return of the Others or a large - scale war. They could be planning to manipulate events so that they are in a safe position, no matter who wins or loses in the power struggles. They might also be trying to protect the Citadel, their center of learning, and a conspiracy could be a way to secure its resources and continued existence.
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.
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.
One possible motive could be protection. Moms often want to protect their children or family. So if there's a threat in the community, like a new development that might bring in dangerous elements, they could conspire to stop it. Another motive might be fairness. For instance, if they notice that the local sports teams are being unfair to their kids, they might plot to make things equal.
A possible crossover could be Ultron taking over the body of a White Walker. This would give him control over the undead army and a terrifying presence in the North of Westeros.
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.
Another plotline might involve a Reyne character getting involved in the political intrigue at King's Landing. They could use their knowledge of the Lannisters' past deeds against House Reyne to manipulate the situation and gain power for themselves and their house.
One possible plotline could be Shirou finding himself in Westeros and using his skills as a swordsman to get involved in the power struggles. Maybe he becomes a knight in someone's service.
One possible plotline could be a character's accidental transformation. For instance, a young character exploring an ancient ruin stumbles upon a magical artifact or spell that causes them to transform into a dragon. This then sets them on a journey to find a way to reverse it or to use their new form for good.
One possible theme could be power struggle. Just like in 'Game of Thrones' where different houses fight for the Iron Throne, in the Russian Revolution, there were various groups vying for power. So, in the fanfiction, this could be a major theme.
In a 'Game of Thrones Epilogue Fanfiction', it could be about the adventures of the next generation. The children of the main characters might discover new threats or mysteries. For instance, they could find hidden secrets about the White Walkers that were not fully explored in the original series, leading to a new quest.
