One common theme is the clash of cultures. Harry's world of Hogwarts and the wizarding Britain is quite different from Elia's world. Another theme could be love and friendship, exploring how they form a bond despite their differences.
Yes, there are some interesting ones. You can start by looking on fanfiction platforms like Archive of Our Own. Just search for 'Harry Potter x Elia Martell' and you'll find a variety of stories with different plotlines and interpretations.
One possible plot could be that through some magical accident or time - traveling spell, Harry Potter is transported to the world where Elia Martell is in danger. Harry, with his quick thinking and powerful magic, uses spells like Protego to shield her from immediate threats. Then, he might use his knowledge of advanced magic to outwit her enemies, perhaps using the Patronus charm to drive away dark creatures sent after her.
It could be Voldemort. Imagine if Voldemort somehow extended his reach into the world where Elia Martell is. His thirst for power and domination could lead him to target Elia for some reason. Harry, having already fought Voldemort in his own world, would be the perfect hero to stop him from harming Elia.
Well, if Robert had married Elia, it might have changed the power dynamics among the noble houses. It could have prevented some of the bloody feuds and wars that happened in the original storyline.
Well, if Elia Martell married Ned Stark, it might have changed the course of many events. Their combined influence could have shaped a more peaceful or at least a differently chaotic kingdom. Also, the relationships among the noble houses might have been very different.
In some fanfictions, a character like Ned Stark might discover the plot against Elia Martell in time and use his influence to protect her. This would create a very different story as Ned is known for his honor. It could lead to a situation where he has to make difficult choices between loyalty to the crown and doing what is right. And this would also impact the relationship between the North and Dorne in ways not seen in the original series.
You can try some popular fanfiction websites like Archive of Our Own (AO3). There are often a lot of different takes on saving Elia Martell in the Game of Thrones universe. Just use the search function on the site and type in relevant keywords like 'Elia Martell' and'saved' to narrow down the results.
In a 'Game of Thrones' fanfic where one is asked to save Princess Elia, it could be a really interesting plot. Maybe the character is a time - traveler or has some special powers. If it's a time - traveler, they might have to go back to before the events that led to her downfall. They'd need to navigate the complex politics of Westeros, make allies, and perhaps even face off against the likes of Tywin Lannister. It would be a dangerous mission, but with enough cunning and strength, it could be possible to change her fate.
One common theme could be forbidden love. Given the setting in which Oberyn Martell exists, a gay relationship might be frowned upon in that society, adding an element of secrecy and danger to the story.
