Well, imagine if the ancient starship had some sort of artificial intelligence still active. In the Game of Thrones world, this would be seen as some kind of powerful spirit or demon. The AI could start influencing the events in Westeros, maybe by giving advice to certain characters. It could choose those who it thinks can bring about a new order or simply those who can help it repair itself. And this would create a whole new layer of intrigue and power struggles.
In a fanfic, the ancient starship could hold the key to a different kind of power than what is known in Westeros. It could be a power that is not based on brute force or political manipulation, but on knowledge. The characters who discover the ship start to learn about new forms of governance, science, and technology. This new knowledge could either be used to better the kingdoms or to further someone's own greedy ambitions.
The Dragonborn could potentially fit into the Game of Thrones universe in several ways. One way is through their dragon - related abilities. In Game of Thrones, dragons are a powerful and rare force. The Dragonborn's natural affinity for dragons could make them a valuable ally or a feared enemy. They could perhaps form alliances with the Targaryens, who also have a strong connection to dragons. Another aspect could be their combat skills. The Dragonborn is often a skilled warrior, and in the brutal world of Game of Thrones, such skills would be highly sought after.
In a fanfic, the Assassin's Creed elements could create some really interesting storylines. The idea of a hidden brotherhood operating in the shadows of Westeros would add a new layer of mystery. They could have their own goals, such as protecting a certain bloodline or preventing the misuse of magic. And their technology, like the hidden blades and the use of smoke bombs, would be a novelty in the medieval - like setting of Game of Thrones. This could lead to some really cool scenes where they use their gadgets to outwit their enemies and make their mark in the complex world of Westeros.
She would be a disruptor. Bellatrix's unpredictable and violent nature would immediately set her apart in the Game of Thrones world. She might not play by the political games' rules and just use her dark magic to get what she wants.
Smaug could potentially be a part of the magical elements in the 'Game of Thrones' fanfiction. He could be connected to the old magic that once existed in Westeros. Maybe his presence awakens other dormant magical forces. His actions could also influence the political landscape. For example, if he attacks a certain region, the lords there would have to divert their resources from the power struggles to deal with the dragon threat, which in turn could give an advantage to other houses.
Kakashi could fit in as a foreign warrior. He could bring his ninja techniques which would seem like magic to the people of Westeros. His stealth and combat skills would make him a valuable asset or a feared opponent in the battles and power plays of the Seven Kingdoms.
She could be a long - lost relative of one of the major houses. For example, if she was related to House Stark, she could come to Winterfell and claim her place in the family. This would stir up a lot of emotions and power plays within the house, especially if some members were suspicious of her motives. It would also give her a connection to the ongoing storylines, like the fight against the Boltons or the preparation for the coming of the White Walkers.
For Sakura, she could be a healer in the Game of Thrones world. With her medical ninjutsu skills, she could treat the wounded from dragon attacks or battles. And she might also learn some of the local magic to enhance her healing abilities, all while having to deal with the political intrigue and power struggles that are so common in the Game of Thrones universe.
Naruto characters could fit in various ways. For instance, Naruto himself could be like a knight errant in the Game of Thrones world. His chakra - based powers would be seen as a strange and powerful form of magic. He might use his Shadow Clone Jutsu to gather information or fight in battles, which would be a very unique ability compared to the normal combat in Westeros.
Link would be an outlier in the GoT world. He's used to a more straightforward good - vs - evil dynamic. But in Westeros, he'd have to navigate the complex web of politics. He could probably be a great warrior in the service of a noble house, but his simple and pure-hearted nature might make him a target for the more devious characters. Zelda could be a powerful sorceress, perhaps on par with Melisandre, but with her own goals and a different moral compass.
