Well, you could write a fanfiction where the dragons have the ability to communicate with humans in a more complex way than just following commands. This could lead to some really intense political situations as different factions try to use this new form of communication to their advantage. You could also explore a scenario where the dragons are not just weapons, but are more like protectors of a certain part of Westeros, and how that changes the whole landscape of power struggles and wars in the series.
One idea could be exploring the backstory of the dragons. Maybe how they were discovered and tamed in more detail. Another could be a fanfiction where a new character has a special bond with the dragons, changing the power dynamics in Westeros.
A great idea for this fanfiction could be a story that focuses on what would happen if the dragons had different personalities. For example, a more mischievous dragon or a very gentle one. It could lead to all sorts of new adventures and interactions within the Game of Thrones world. Also, a fanfiction about a character from a minor house who uses their wits and the power of the dragons to rise to prominence would be really interesting.
Arya Stark could be a very interesting central character in this fanfiction. She's a fierce and resourceful character. Picture her sneaking around with the help of the dragons or using them to exact revenge on her enemies. Tyrion Lannister is also a great candidate. His intelligence combined with the power of the dragons could lead to some really unique storylines, like him using the dragons to broker peace deals or gain political power in new ways.
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 idea could be a self - insert character who has the ability to communicate with the dragons on a deeper level. They could use this to prevent some of the tragic events in the series, like the destruction of King's Landing by Drogon. Another plot could involve the SI becoming a dragon rider and using their modern knowledge to train the dragon in new ways, for example, teaching it advanced aerial maneuvers.
One idea could be the Ice Dragon forming an unexpected alliance. Maybe it teams up with a group of outcasts in Westeros, like a band of wildlings and a disgraced knight. Together, they journey across the frozen North, facing White Walkers and uncovering ancient secrets about the dragon's origin.
One idea could be exploring what would happen if a minor character, like Gendry, had a more prominent role in the story. He could potentially become a powerful lord and change the political landscape.
A great idea for 'Game of Thrones fanfiction' is to rewrite the story from the perspective of the smallfolk. For instance, how did they really feel during all the wars and power struggles? How did the common people in King's Landing cope with the different rulers? You could also explore a fanfiction where the White Walkers are not the villains. What if there was a misunderstanding and they were actually trying to protect the realm from some other greater threat?
One idea could be exploring what would happen if Jon Snow was raised by the Starks as a trueborn son. Another could be a fanfiction about Daenerys Targaryen's journey if she had made different alliances earlier. Or perhaps a story about Arya Stark training with a different master assassin.
A great concept for a dragon OC in a fanfiction is a dragon that has the ability to communicate telepathically with not just its rider, but also other dragons. This could lead to some really interesting plotlines, such as the dragon being able to broker peace between rival dragon - ridden factions. In the story, it could be that this dragon OC was born during a rare celestial event, which is why it has this special ability.
One idea could be a character who is initially a lowly servant in King's Landing. After a strange encounter with an ancient magic, they start to transform into a dragon. As they gradually turn, they gain new powers like the ability to breathe fire in small spurts. This causes chaos as they try to hide their transformation from the power - hungry lords and ladies of the court. They might also start to have dreams of flying over the Seven Kingdoms, which drives them to seek out the knowledge to fully complete their transformation.
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.
