If Arya Stark becomes the Night Queen in a fanfic, it would be quite a shock to the system. Arya has always been a fighter against the forces of darkness, so her becoming the Night Queen would be a complete role reversal. One possible plot could be that she is forced into this position against her will, perhaps by some ancient magic or a deal gone wrong. Then, she has to navigate her new identity while still holding on to some of her old values, which could lead to a lot of internal conflict.
If Arya becomes the Night Queen, her personality might become more cold and calculating. She has always been a survivor, but as the Night Queen, she would need to be more ruthless to control the White Walkers. Her sense of humor and playfulness might disappear as she takes on this dark and serious role.
As Queen of the North, Arya's character would transform significantly. Her wild and independent streak would still be there, but she'd learn to channel it in a more productive way. She'd start to understand the importance of traditions and how they can be used to unite the people. Her relationship with power would be complex. On one hand, she'd use it to protect the North, but on the other, she'd be cautious not to let it corrupt her. She'd develop a more regal presence, but still keep her roots as a Stark. Her skills as a spy and assassin would be used in more strategic ways, like uncovering plots against the North and eliminating threats without causing unnecessary chaos. And she'd have to learn to balance her personal desires with the needs of her kingdom.
She might use her new role to bring justice in a different way. Maybe she'd secretly punish the corrupt nobles who escaped regular justice. The Stranger is often associated with death and the end, so Arya could be the one to end the reigns of tyrants in the fanfic world.
Her relationships would become more complex. Her family might not recognize her at first, and when they do, they might be afraid. Her friends could be both in awe and a bit scared of her new identity.
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.
One great Arya Stark dancer fanfic could be 'Arya's Dance of Freedom' which explores Arya's journey through dance in a unique way. It shows her using dance not just as an art form but also as a means of self - expression and survival in a dangerous world.
Jon Snow could be paired with Arya. They could go on a quest to find something important, like a long - lost heirloom of House Stark. Along the way, they share stories of their past adventures and strengthen their bond as siblings, while also facing various challenges from the elements and enemies.
One possible story could be Arya using her assassin skills to protect the North. She might face threats from the South or from within her own territory. For example, there could be lords who don't want to be ruled by a young woman. But Arya, being Arya, would use her wits and combat abilities to outmaneuver them.
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 great fanfic could be about Arya Stark rebuilding Winterfell as the last Stark. It might explore how she uses her skills she learned during her travels to bring back the glory of her family's home. She could train new guards, establish trade routes, and make Winterfell a stronghold again.
