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.
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.
A young girl from a small village near the Wall could be a great main character. She could be an orphan who has a special connection with nature. One day, she finds a dragon egg while exploring a cave. She has no idea what it is at first, but she feels drawn to it. As she takes care of the egg, she starts to develop powers of her own that are related to the dragon's magic. Eventually, she hatches the dragon and becomes a powerful figure in the North.
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.
Maybe the last dragon is the key to unlocking some long - forgotten magic in the world of Game of Thrones. It could lead to the discovery of ancient prophecies or hidden lands. And as it grows, it attracts the attention of different factions, all vying to control it for their own purposes. Some might want to use it for good, like protecting the realm from a new threat, while others seek to use it for domination.
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.
One idea could be to create a demon character who has the power to manipulate the minds of the main Game of Thrones characters. This demon could be working behind the scenes to cause chaos and further the power struggles already present in the story.
One idea could be Merlin being a hidden advisor to one of the major houses in Westeros. He uses his magic secretly to influence events and protect the realm, much like he did in the Merlin series but in the Game of Thrones setting.
