Magic would likely be a game - changer. It could be used for both good and bad. Wizards could use magic to heal the wounded in the battles of Westeros, or they could use it to gain an unfair advantage in the power struggles. For instance, a wizard could magically control the minds of the smallfolk to support a certain claimant to the Iron Throne.
In this fanfic, magic might have different rules. Maybe the magic from Harry Potter doesn't work as well in the world of Game of Thrones due to some ancient magic that already exists there. Or perhaps it's the other way around, and the magic of Westeros could enhance the magic of the wizards. The dragons might be immune to some of the spells, and this could create interesting plot twists when wizards try to face them.
The magic system could be affected by the radiation in the Fallout world. Spells might have different effects or require more effort to cast. For example, the Patronus charm could be harder to conjure due to the gloomy and desolate nature of the Fallout setting.
The healer's abilities would have to be adjusted to fit the different settings. In Game of Thrones, the medical knowledge is more primitive compared to Harry Potter. So, a healer from the Potter world would seem like a miracle - worker. They could use their magic to heal diseases that are considered incurable in Westeros, like greyscale. But they would also have to be careful not to be seen as a threat by the powerful families and the maesters who hold the traditional medical knowledge. They might need to work in secret or find a way to collaborate with the local healers to gain acceptance.
Well, Harry's magic could be affected by the technology in the SG1 universe. Since SG1 is so technology - driven, there could be interference. For example, his levitation charm might not work as well around advanced Goa'uld technology because of the energy fields they produce. But on the other hand, his magic could also be enhanced by some ancient alien artifacts that have a connection to magic in a way he doesn't expect.
His magic could be used for things like healing the wounded during battles, which would be a huge advantage. Also, he could use spells to protect castles from attacks, like a magical shield. In terms of communication, he could use something like the Patronus to send messages long - distance, similar to the ravens in Game of Thrones.
A 'Harry Potter - Game of Thrones' lemon fanfic would be a very strange and probably inappropriate concept. Since 'lemon' often implies sexual content in fanfic jargon, it would be a very odd mix with the magical world of Harry Potter and the medieval - like world of Game of Thrones. It would likely deviate from the original tones and themes of both series.
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.
Harry's magic would be a game - changer. His ability to apparate could make travel and espionage much easier. For example, he could easily get into the Red Keep undetected. This would give him an edge over the regular characters in GoT who rely on horses and ships.
In 'Game of Thrones' fanfiction, the harem concept often involves a powerful character, like a lord or a queen, gathering a group of people (usually of the opposite sex) around them. These individuals in the harem can be used for political gain, like forging alliances through marriage, or for personal support. In 'Harry Potter' fanfiction, it's a bit different. For example, if Harry has a harem, it might be more about friendship and mutual magical exploration at first, which then develops into deeper relationships.
Well, it might look like Hogwarts being placed in Westeros. The houses in Hogwarts could interact with the different houses in Game of Thrones. Gryffindors could team up with the Starks, known for their honor. Slytherins might find common ground with the Lannisters, being cunning and power - hungry. And the magic of Harry Potter could be used to change the fates of the characters in Game of Thrones. Maybe Hermione could use her intelligence to outwit Littlefinger, or Ron could befriend some of the knights in Westeros.
Well, Harry Potter would be a very different character in the Game of Thrones world. He'd probably have to deal with the complex politics there. Maybe he'd use his magic to outwit the scheming lords and ladies. He might also form alliances with some of the more honorable characters like Jon Snow. Magic could be seen as a powerful but also very dangerous tool in Westeros, so he'd have to be careful not to draw too much attention to himself.
