Well, perhaps the company is a group of artisans. They create unique weapons and armor for the different factions in Westeros. Their work catches the eye of a powerful king, who wants them to create something extraordinary for him. But they also have a secret agenda - to use their creations to influence the balance of power. They might befriend a young knight and help him rise to prominence, all while furthering their own goals.
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 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.
One idea could be a crossover where characters from Rome end up in the world of Game of Thrones. For example, Julius Caesar arriving in Westeros and trying to conquer it with his military tactics. Another could be a story about a gladiator from Rome who finds himself in the middle of the power struggles in King's Landing.
Well, a cool plot for a 'warden game of thrones fanfic' might be that the warden stumbles upon a secret passageway that leads to a hidden treasure. But this treasure is not just gold, it's a powerful weapon that was used in the ancient wars of Westeros. As he tries to keep it a secret, word gets out and he has to fend off various factions who want it for themselves. Or perhaps the warden is visited by a mysterious figure from another land who claims to have knowledge of a future disaster that will befall Westeros if certain actions are not taken.
Well, you could write a fanfic where Arya Stark decides to use her skills not for revenge but for building a new society in the ruins of Westeros. She could start a school for orphans and teach them self - defense and survival skills. Also, a plot where Bran Stark uses his powers to travel back in time and prevent some of the worst events from happening, like the Red Wedding. And a fanfic about how Jaime Lannister redeems himself in a more public way by protecting the smallfolk during a great war.
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.
A plot idea could involve Jon and Daenerys having to face a common enemy that is not the Night King. Suppose a new and powerful warlord rises in Essos and decides to invade Westeros. Jon and Daenerys would have to combine their forces, not just their military but also their diplomatic skills. Daenerys' experience with different cultures in Essos and Jon's knowledge of the North and the Seven Kingdoms would be put to the test as they try to form alliances against this new threat.
