What are the possible plotlines in 'Game of Thrones' - 'Harry Potter' crossover fanfiction with a ukulele?

I'm not sure specifically about fanfictions that involve a ukulele in a 'Game of Thrones' - 'Harry Potter' crossover. But you could try searching on popular fanfiction websites like Archive of Our Own. They have a wide range of fanfictions and you can use specific search terms to narrow down your results.

One possible plotline could be the Hogwarts students being transported to the world of Game of Thrones and having to navigate the political intrigue and power struggles using their magic. For example, Hermione could use her intelligence and knowledge of spells to outwit the scheming lords in Westeros.

A Harry Potter - Game of Thrones fanfiction about finding gold could have a lot of potential. Picture Dobby the house - elf from Harry Potter helping Arya Stark from Game of Thrones. Dobby's magic could be used to unearth hidden gold, while Arya's combat skills and stealth would protect them from those who would try to steal their new - found wealth. This kind of crossover would bring together two very different but equally beloved fictional worlds.

Another plotline might involve a Reyne character getting involved in the political intrigue at King's Landing. They could use their knowledge of the Lannisters' past deeds against House Reyne to manipulate the situation and gain power for themselves and their house.

One possible plotline could be Shirou finding himself in Westeros and using his skills as a swordsman to get involved in the power struggles. Maybe he becomes a knight in someone's service.

One possible plotline could be a character's accidental transformation. For instance, a young character exploring an ancient ruin stumbles upon a magical artifact or spell that causes them to transform into a dragon. This then sets them on a journey to find a way to reverse it or to use their new form for good.

One possible plotline could be the characters in the afterlife having to atone for their sins. For example, characters like Joffrey might face some sort of punishment or redemption arc in the afterlife realm. Another could be the great heroes of Westeros coming together to fight against some new threat that exists even in the afterlife. Maybe they have to stop a dark force from spreading chaos among the souls. And perhaps the Starks and Lannisters could put aside their differences and work towards a common good in this afterlife scenario.

One plotline could involve Clark Kent trying to find a way back to his own universe while being stuck in the Game of Thrones world. Along the way, he might form alliances with characters like Jon Snow or Daenerys. He could teach them about his values of truth and justice, and in return, they could teach him about the ways of Westeros. He may also have to face challenges from the various magical elements in the Game of Thrones world, such as the Children of the Forest or the Three - Eyed Raven.

One interesting plotline could be Harry using his magic skills in the world of Westeros. For example, he might use spells to defend against the White Walkers. Another could be his interactions with the different houses, like forming an alliance with House Stark through his friendship with Jon Snow.
