In this fanfic, it might also play with the idea of magic and digestion. Dragons are magical creatures. If they have the ability to 'vore', it could be interesting to see how magic is involved in that process. Maybe the things they 'vore' are transformed in some magical way inside them, or it could be related to how they gain or lose power through this act.
One interesting idea could be the unique power dynamics. Dragons are already powerful in 'Game of Thrones', and in a vore - related fanfic, it might explore how their ability to 'consume' in that sense changes the relationships with other characters. For example, it could create a new level of fear or respect among the humans in Westeros.
Maybe a fanfic could explore what if a group of outcasts, exiled from their own lands, found a dragon egg. They don't have the knowledge of the Targaryens about dragons, but they try to hatch it through trial and error. They build a makeshift nest with whatever materials they can find in the wild. The process of hatching could be filled with near - misses and setbacks, but finally, the dragon emerges, changing their fates.
A fanfic could focus on the dragons in both worlds. In 'Game of Thrones', Drogon and his siblings are unique. In 'Dragon Age', there are different dragon types. The story could explore how the dragons from the two worlds interact. Perhaps a character tries to tame a 'Dragon Age' dragon using the knowledge of dragon taming from 'Game of Thrones'.
Well, perhaps the return of the dragon brings with it a long - forgotten magic. This magic could start to affect the land, the people, and the political situation. For example, it might revive ancient prophecies that people had dismissed, causing chaos as everyone tries to figure out what they mean in relation to the dragon's return. And the dragon might have a special bond with a certain character, like a young, unknown heir who then becomes a key figure in the new power struggle.
One idea could be a fanfic that focuses on the backstory of a minor character, like Gendry. Explore his life before he met Arya, how he survived on his own in King's Landing, and his early days as an apprentice to the blacksmith. Another could be a story set in a different part of Westeros during the events of the main series, perhaps in Dorne, and show how the political unrest there affected the common people. A third idea would be to create a fanfic where the White Walkers are not the main villains, but instead there is a new, more insidious threat emerging from within the Seven Kingdoms itself.
One idea could be to write a fanfic about a character who was thought to be dead but actually survived and is secretly plotting revenge. For example, a Stark family member who everyone believed perished in the Red Wedding.
One idea could be to explore the backstories of minor characters in Yi Ti. For example, a young servant in a noble house who has dreams of rising above his station. He could get involved in political intrigues that mirror the larger power struggles in Westeros.
One idea could be a story about a commoner who discovers a long - forgotten dragon egg and becomes a rider. This person then has to navigate the complex politics of Westeros while hiding their new - found power.
One interesting plot idea could be exploring what would happen if a minor character, like Gendry, had secretly been trained in magic all along. He could use his newfound powers to try and claim the Iron Throne in a different way than the main characters. Another idea is a fanfic set in the past, showing how the relationship between the Starks and the Lannisters first started to sour. Maybe a long - forgotten event that set the stage for all their future conflicts.
Another idea is that Bran Stark uses his powers not just to be the king, but to bring back some of the characters who died in the original series. For example, he could bring back Ned Stark to help in the rebuilding of Westeros. This would be a huge change from the original ending and would give the story a more hopeful and redemptive feel.
One idea could be a fanfic where characters from different houses form an unlikely alliance to face a new, greater threat that was not in the original series. For example, a group of Stark, Lannister and Targaryen descendants coming together.
