Often, there could be a young and idealistic character who leads the uprising. Maybe a bastard son or daughter of a noble house who has seen the injustice in the system. Another could be a former slave who has escaped and now wants to free all his fellow slaves. And there might be a maester who has been exiled from the Citadel for his radical ideas and joins the uprising.
The main characters in the Uprising Game of Thrones fanfiction can vary greatly. One could be a self - taught healer who has seen the poor medical conditions of the common people and decides to lead an uprising for better healthcare. Another might be a young lord who has been overshadowed by his older siblings and uses the discontent of the people to start an uprising to gain power for himself. There could also be an old warrior who has retired from battles but is called back to action when he sees the need for an uprising to defend the rights of the people he once fought for.
There could be a young, ambitious knight who has seen the injustices in the Seven Kingdoms and becomes a key figure in the uprising. Another might be an old and wise maester who secretly supports the uprising and uses his knowledge to help the rebels. Also, a strong - willed noblewoman who has her own reasons for wanting change could be one of the main characters.
It could be a new character created specifically for the fanfiction. This character might be an outcast from a noble house who receives the call and is thrust into the center of the power struggles in Westeros.
Often, the Gravewalker themselves is a main character. They usually have a mysterious past and special abilities. There could also be characters from the original Game of Thrones series who interact with the Gravewalker. For example, Jon Snow might cross paths with the Gravewalker and they could form an alliance or be at odds. Daenerys could also be involved, perhaps seeing the Gravewalker as a threat to her claim to the Iron Throne.
In some fanfictions, Jon Snow could be a central figure when combined with the angel elements. Imagine an angel bestowing upon Jon some new powers or knowledge that helps him in his fight against the White Walkers. And there could be a female angel character who has a special bond with Jon, guiding him not just in his battles but also in his personal growth as a leader.
A young and clever maid in the service of one of the noble families in Queensgate could be a main character. She might be privy to a lot of secrets and use her wits to navigate the dangerous political waters. Maybe she overhears a plot against her master and has to decide what to do about it.
One interesting plot could be the uprising of the smallfolk against the corrupt lords. They might form their own militia and fight for better living conditions. Another could be an uprising within a Great House, like a group of younger members challenging the traditional leadership. And there could also be an uprising of the Night's Watch against the political interference from the Seven Kingdoms.
Arya Stark is a key character. She witnesses the murder of her father and embarks on a journey to avenge her family. Sansa Stark starts as a naive girl but grows into a strong and politically astute woman. Cersei Lannister is a complex character. Her love for her children and her thirst for power drive much of her actions, and she faces many challenges and ultimately meets her end.
One main character could be a genetically - enhanced human who has special abilities, like Arya Stark's skills in the original. She could be on a mission to avenge her family who were killed by a powerful space - faring clan. There could also be a powerful warlord from a distant star system, a bit like Ramsay Bolton, feared for his cruelty and thirst for power. The interactions between these diverse characters would drive the story forward in this space - based Game of Thrones fanfiction.
Cinderella would be a central figure. For the male lead, it could be a young and noble - hearted character like Robb Stark. He has the charm and leadership qualities similar to a prince. The stepmother could be a power - hungry noblewoman, like Cersei Lannister in some ways. The stepsisters could be her daughters, who are jealous of Cinderella's beauty and the attention she gets from the young lord. And then there could be other 'Game of Thrones' characters like Tyrion Lannister as a side character providing some wisdom and humor.
Myrcella is obviously one of the main characters. Since it's a fanfiction centered around her, she would be the focal point of the story.
