A possible plot point could be Arya's relationship with the people of Winterfell. She has been away for a long time, and now she has to earn their trust again. She might use her newfound knowledge and skills to improve the lives of the common folk, like dealing with food shortages or protecting them from bandits, which would be an engaging part of the fanfic.
One interesting plot point could be how Arya uses her unique skills learned during her travels to defend Winterfell. For example, her skills in stealth and assassination might be used to uncover and thwart hidden threats within the castle.
Arya's character might develop in terms of her leadership skills. From being a lone wolf, she has to become a leader. She'll learn to make decisions for the greater good of Winterfell, not just for her own survival.
One possible plot is that Arya comes back to Winterfell with new allies she made during her adventures. These allies could be from different regions or cultures, and they bring with them unique skills and knowledge. Her return might also stir up old rivalries among the people in Winterfell. Some might be jealous of her newfound skills and experiences, while others might see her as a symbol of hope. And as she settles back into Winterfell, she has to navigate the complex web of relationships and power dynamics that have changed in her absence.
One possible plot development could be Arya reuniting with her family members. She might share her adventures and skills she has acquired during her time away. Another could be her getting involved in the political affairs of Winterfell, using her wits to help protect the castle and its people.
Arya could encounter old friends like Gendry. Their relationship might have evolved during her time away, and there could be new feelings or just a strengthened bond of friendship. Also, she may come across some of the younger Stark bannermen who have grown up in her absence and now look up to her as a hero.
One idea could be Arya traveling back to the time before her family's downfall. She could use her skills to prevent certain events from happening, like Ned Stark's execution. Maybe she'd change the course of battles by secretly assassinating key enemies.
One plot idea could be Arya having to deal with political intrigue in the North. Maybe there are rival lords who don't fully accept her as Queen and she has to outwit them. Another could be Arya facing an external threat like a new wildling uprising, but she uses her unique skills to handle it. And perhaps she could be on a quest to find a long - lost Stark heirloom that is said to have the power to unite the North even more firmly under her rule.
Family is a very common theme. Since the Starks are a large and important family in Winterfell, many fanfics explore their family bonds, loyalty, and rivalries. Another common theme is survival, especially during the harsh winters that Winterfell often faces.
She will most likely interact with her siblings, like Sansa. They could have a heart - to - heart conversation about their past experiences and how they have changed. Also, Jon Snow might be one of the characters she meets. Their relationship could be further explored, especially considering Jon's leadership in Winterfell.
One interesting plotline could be Arya and the Hound facing a new and powerful enemy together. Maybe they encounter a group of bandits with a cruel leader, and they have to use their combined skills to defeat them.
One interesting plot point could be the reaction of the other Stark family members. If Arya was in a situation where she was thought to be pregnant, how would Sansa react? Would she be supportive or judgmental? And what about Bran, with his all - seeing abilities? His knowledge could add a whole new layer to the story. Also, how would Jon handle the situation within the context of his role as a leader or protector? It could lead to some great character - driven drama.
