There's also 'Jon Snow: The True Heir'. It plays with the idea that Jon Snow has a more significant role in the grand scheme of things. It delves into his backstory and his potential future, all while maintaining the dark and gritty feel of the original 'Game of Thrones' world.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of 'Game of Thrones' fanfiction, and you can sort by popularity and ratings. That way, you can easily find the ones that are highly regarded by other fans.
I liked the 'Games of Thrones' and 'Harry Potter' crossover fanfiction. In this, they brought the magic of Hogwarts into the world of Westeros. The wizards had to deal with the political intrigue and the harsh reality of the Seven Kingdoms. It was cool to see spells being used in battles against knights and the like. And the way the houses in 'Game of Thrones' reacted to this new form of power was really engaging to read about.
Well, Reddit can be a great source too. There are subreddits dedicated to 'Game of Thrones' fanfiction. People often share their new works or recommend good ones they've read. Just search for relevant subreddits and browse through the posts. You might stumble upon some really cool new fanfictions. Also, some Tumblr blogs are focused on 'Game of Thrones' fan-created content, including fanfiction.
A great 'phoenix' in GoT fanfiction might be a magical creature that only certain characters can see. It could be a guide for a young hero or heroine on their journey. Maybe it leads them to hidden treasures or secret knowledge that helps them in the power struggles within the Seven Kingdoms.
Well, you could write a Games of Thrones fanfiction where the dragons have different personalities. Maybe one dragon is super friendly and tries to make peace between all the warring factions. Another idea is to create a story set in the past, during the time of Aegon the Conqueror, but with a twist. For example, what if there was a powerful female sorceress who tried to stop Aegon's conquest? And a fanfiction about how the smallfolk deal with all the chaos of the wars and power struggles among the nobles would also be quite interesting.
Character development is key. When bringing characters from different universes together, show how they adapt and change. In a 'Games of Thrones' and 'Sherlock Holmes' crossover, for instance, Sherlock's deductive skills would be put to the test in the complex world of Westeros. And the GoT characters would have to deal with Sherlock's no - nonsense approach. Also, keep the tone consistent with the original 'Games of Thrones' feel. Dark, gritty, and full of political drama.
I really liked 'The Red Woman and the Devil'. It's a fanfiction that brings together Melisandre from Game of Thrones and Lucifer. The way it explores their different views on magic and the afterlife is really interesting. Then there's 'Jon Snow and Lucifer: An Unlikely Alliance' which has an interesting take on how two very different characters from different universes could work together. And 'Daenerys in Lucifer's World' is great too. It shows how Daenerys would navigate a world full of modern - day devils and angels, using her wits and her dragons.
One great 'Game of Thrones' Varys fanfiction is 'The Spider's Web'. It delves deep into Varys' past and his motives in a really interesting way. It shows his early days in Essos and how he came to be the master of whispers in Westeros. The author does a wonderful job of staying true to his character as we know it from the show and books.
One great 'Game of Thrones Vengeance Fanfiction' is 'The Vengeful Wolf'. It follows Arya Stark as she returns to Westeros with a new set of skills and a burning desire for vengeance against those who wronged her family. The story is full of action and stays true to the complex world of Game of Thrones.
