One main plotline is the battle for the Iron Throne among various noble houses. The Stark family, for example, gets involved in a complex web of power struggles after Ned Stark's death. Another is the threat of the White Walkers from the North. Daenerys Targaryen also has her own plotline as she tries to reclaim her family's throne and free slaves across Essos.
The 'Game of Thrones' book series end is still a mystery. But if we look at the themes that have been running throughout the story, such as power, loyalty, and family, we can expect these to be resolved in some way. Maybe there will be a new order established in Westeros, different from the feudal system that has been in place for so long. The characters who have survived all the chaos will have to adapt to this new world. Also, the magic and supernatural elements, like the dragons and the Others, will likely have a significant impact on how the story concludes. For example, the dragons could either be a force for destruction or a means of uniting the kingdoms under a single rule.
One possible ending could be that Daenerys Targaryen takes the Iron Throne and rules Westeros with a new form of governance. Another could be that the kingdoms split into smaller, independent regions.
Jon Snow is really memorable. He has to deal with his identity as a bastard while also taking on important responsibilities at the Wall. Jaime Lannister is another one. His character arc from being seen as a 'kingslayer' to a more complex figure is fascinating. And then there's Ned Stark. His sense of honor, even though it ultimately led to his downfall, makes him a character that readers can't forget.
Mostly. The story maintains the themes of power, loyalty, and betrayal that are central to the original series. However, it also takes some creative liberties to fit the interactive, choice - driven format of the game.
In terms of creativity, the fanfic can be more unrestrained. The original series has certain boundaries set by the showrunners and the source material. But in 'game of thrones shadowmer fanfic', the author can come up with wild ideas like new magical elements or alternative political systems that don't have to fit within the framework of the official 'Game of Thrones' lore. However, this also means it might lack the polish and production value of the original series.
