In Stark fanfiction, magic can often be a hidden or emerging power. It might manifest in a Stark's dreams, like premonitions similar to Bran's warging abilities. For example, a fanfic could have Sansa Stark developing a magical connection to the old gods, allowing her to foresee threats to Winterfell.
Magic in Stark fanfiction can also be a means of resurrection or protection. Maybe a Stark is brought back from the brink of death using some form of magic. It could be tied to the ancient magic of the North. For instance, Arya Stark might be protected by a magical charm that hides her from the White Walkers.
In the case of Varys, being a eunuch affected how others perceived him. This led him to develop a very shrewd and calculating personality. He had to rely on his wits and intelligence rather than physical strength or family connections. His castration was a driving force behind his rise to power in the political intrigue of Westeros, as he had to find other ways to assert himself.
The Blackfyre family in fanfics can also be a symbol of lost glory and a catalyst for change. Some fanfics might depict a Blackfyre heir who has been in exile for years, coming back with new ideas and a different perspective on ruling. This heir could try to unite the fractured kingdoms under the Blackfyre banner, which is a very different approach compared to the power struggles we see in the original series. This can lead to interesting character interactions and plot developments as other houses either support or oppose this new movement.
Sansa's character development in fanfiction varies from the show. In the show, her development was a gradual process that sometimes felt rushed. In fanfiction, authors can take their time to really flesh out her growth. They can explore her internal thoughts and feelings more deeply. For instance, when she was dealing with the trauma of her experiences, fanfiction can go into greater detail about how she overcame it and how it shaped her into the person she becomes, rather than just showing the end result as the show sometimes did.
A female Stark OC could play the role of a peacemaker. For instance, if there are disputes between different Stark siblings or between the Starks and other houses. She could use her diplomatic skills, which she might have learned from observing her father. Her calming presence and ability to see different perspectives would help in resolving conflicts.
In fanfiction, Tony Stark's smile can be a plot device. It might signal to other characters that he's up to something. For example, his sly smile could mean he has a clever strategy in mind.
A Dragon Warden in a Game of Thrones fanfic might play the role of protector. They would safeguard the dragons from those who would seek to harm or use them for evil purposes. This could involve fighting off other powerful characters or groups that want to capture the dragons for their own gain.
Snow often refers to Jon Snow in 'A Game of Thrones'. He plays a crucial role. He is a central character in the complex web of power struggles and family feuds. He starts as an outcast in the Stark family due to his bastard status but rises to become a respected leader. His time at the Wall, where he joins the Night's Watch, exposes him to the threat of the White Walkers. His leadership skills and ability to unite different groups, like the wildlings and the Night's Watch, are vital in the fight against the common enemy, which is the approaching army of the dead.
She could be a healer. With her knowledge of medical ninjutsu, she could save many lives in the war - torn Westeros. This would make her a valuable asset to any side she chooses to support.
He could be a heroic figure. For example, he could be like a knight - errant, traveling around Westeros and helping those in need. His swordsmanship, which is quite different from the traditional Westerosi style, would make him a unique combatant.
He could play the role of a master strategist. Thrawn's ability to analyze his opponents and predict their moves would make him a valuable asset to any side in the 'Game of Thrones' power struggles. He could be the one to turn the tides in battles and sieges.
