I think so. Consider how many different cultures and factions exist in the 'Game of Thrones' universe. Each one can be the focus of a fanfic. And with new fans coming in over time, they will bring fresh perspectives. They might want to explore how a character from a minor house could change the course of events, for example. So, yes, more fanfic will come.
A 'Game of Thrones' future fanfic might explore the consequences of the events in the original series. For instance, if Jon Snow's true identity becomes widely known, how would that reshape the political landscape? Some might see him as the rightful heir and support his claim to the Iron Throne, while others might oppose him out of fear or self - interest. Also, the White Walkers' threat might not be fully over, and there could be a resurgence of the undead in a different form.
Well, if Arya is teleported to the future in a fanfic, she might initially be hunted. The future society could see her as a threat or an anomaly. However, as she learns about the future, she could also find allies. For example, there could be a group who are interested in the old ways and want to learn from her. She might then use her teleportation as a way to gain an advantage, perhaps by teleporting to places that are key to the future world's power structure and trying to change things for the better, or at least to find a place for herself in this strange new time.
The children of the forest might play a more important role. They have ancient knowledge and magic. Maybe they decide to interfere more in the affairs of men, either to protect the natural world or to exact revenge on those who have wronged them in the past. Their presence could bring about a whole new set of rules and challenges for the human characters.
One interesting concept could be the evolution of the political landscape. Maybe new houses rise to power or old alliances are completely re - shaped. For example, a previously minor house might gain significant influence due to some new discovery or event.
She'd be shocked. The future would likely have no concept of the Iron Throne or the old feudal systems. Arya would have to quickly figure out how to survive. Maybe she'd use her ability to change faces to blend in, but she'd still stand out because of her archaic fighting style.
Another aspect could be the exploration of magic. Since the world of Game of Thrones has magic that was somewhat in the background in the original series, in the future story it could become more prominent. There could be new magic users emerging, perhaps some who use magic for good and others for evil, leading to a new kind of magic - based conflict.
I think Bran Stark could be very interesting too. As the Three - Eyed Raven, he has vast knowledge and powers. In a future fanfic, he could use his powers to foresee and prevent new disasters or to guide the future of Westeros in a more positive direction. However, his new powers might also make him a target for those who fear his influence.
