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.
In some fanfics, Arya Stark might be presented as the last Stark, but it really depends on the specific plot and direction the fanfic author takes. There could be plot twists where other Starks are revealed to still be alive.
It could be a bastard child of a Stark that was kept hidden for some reason. Maybe for fear of political ramifications or because of some dark family secret.
Common themes include the bond of family, which is shown through their daily interactions, like Tony reading bedtime stories to Morgan. The theme of mentorship also pops up, as Tony imparts his knowledge and skills to Morgan. Additionally, there is often the theme of loss and remembrance, as in how Morgan copes with the loss of her father and how she keeps his memory alive in different ways in the fanfics.
Another idea for a fanfic is that Arya discovers she's not really the last Stark. There could be a long - lost relative hidden away. She then embarks on a journey to find this person. Along the way, she has to overcome many obstacles and face new enemies, all while trying to keep the hope of the Stark family alive.
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.
There are several Morgan Stark x Tony Stark fanfics out there. 'Stark Family Moments' is a heartwarming fanfic that depicts various interactions between them. It includes cute scenes like Tony teaching Morgan about science. Also, 'Morgan's Hero' shows how Morgan sees Tony as her ultimate hero, with a lot of emotional depth in their relationship.
A Stark family game night with a Shireen fanfic could be really interesting. It might involve the Stark family members gathering for a game night, and perhaps in this fanfic, Shireen could be an unexpected guest or have some special connection to the Starks. Maybe she brings a new game from her own region that the Starks have never played before, adding an element of novelty and excitement to the game night.
One great Arya Stark and Sandor Clegane fanfic is 'The Hound and the Wolf'. It beautifully explores their complex relationship as they journey together. The author does a wonderful job of delving into their characters, showing Arya's growth and Sandor's transformation.
