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.
In this fanfic, a possible plot could be that the return of the dragon is tied to an otherworldly threat. The dragon is the only hope to defeat this threat, but the different kingdoms are too busy fighting among themselves to realize it at first. As the dragon roams Westeros, it starts to gather a group of loyal followers who see the bigger picture. This group has to overcome not only the external threat but also the internal politics and power - hungry lords who don't want to cooperate.
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'.
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.
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 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 that Elsa is a powerful sorceress from a far - off land who arrives in Westeros during the War of the Five Kings. She could use her ice powers to control the weather and influence battles. For example, she might freeze the moats of castles to make them easier to invade or create ice bridges over rivers.
Well, a cool plot for a 'Game of Thrones Machinist' fanfic could involve a machinist who is an outcast but has incredible skills. He could be hired by Daenerys to build some sort of war machines for her army. Maybe he creates a huge catapult that can launch fireballs over long distances. Or he could be forced to work for the Night King, building devices to break through the Wall. In this way, the machinist's skills become a crucial part of the power struggle in Westeros.
One idea could be a character reincarnated as a different species, like a dragon. They could then use their new form to influence the power struggles in Westeros. Another could be a reincarnated character remembering key events from the original series and trying to prevent certain tragedies from occurring. For example, if Ned Stark was reincarnated, he might be more cautious and avoid getting caught in the political traps that led to his downfall.
One idea could be to explore the origin of Ulthos. Maybe it was a hidden land filled with ancient magic that was long forgotten. A character from Westeros could accidentally discover a map leading to Ulthos and embark on a journey full of strange creatures and unknown cultures.
