One idea could be a character from 'Dishonored' getting transported to the world of 'Game of Thrones'. Maybe Corvo could use his powers to navigate the dangerous political landscape of Westeros. He could use his blink ability to quickly move through the Red Keep, unseen by guards, and gather information that could change the balance of power among the houses.
Another interesting concept is a story where the events of 'Dishonored' lead to the creation of a new house in 'Game of Thrones'. For example, if a group of characters from 'Dishonored' settle in Westeros, they could form their own house with their own unique set of values and abilities. This new house could then get involved in the power struggles and wars of Westeros, bringing their own brand of combat skills and magic along.
In 'Game of Thrones Crossover Fanfiction', a cool concept would be crossing it with 'Alice in Wonderland'. Alice could wander into Westeros and disrupt the power balance with her strange and magical ways. Another idea is to cross it with 'The Hunger Games'. Have the districts be like the different regions of Westeros and the Capitol be King's Landing. And a crossover with 'Supernatural' where the Winchester brothers hunt down the supernatural threats in Westeros.
Well, for a 'a game of thrones crossover fanfiction', a crossover with 'Star Wars' would be cool. Picture the Nights Watch using lightsabers to fight the White Walkers. Or a crossover with 'The Matrix'. What if characters from Game of Thrones were trapped in the Matrix? Also, a crossover with 'Sherlock Holmes'. The detective skills of Sherlock could be used to solve the mysteries in Westeros.
A Dishonored crossover fanfic could involve a crossover with the Assassin's Creed universe. Maybe Altair or Ezio could end up in Dunwall and learn about the Outsider's mark and the unique stealth mechanics there. They could exchange techniques and fight together against the corrupt powers in Dunwall. It would be really cool to see how their different fighting styles and cultures interact.
In a Halo - Game of Thrones crossover fanfiction, the Forerunners' technology could be a huge factor. What if some of the Forerunner artifacts ended up in Westeros? Different houses might try to claim them, thinking they hold great power. The characters in Game of Thrones would be in awe of the advanced technology, and there could be a race to unlock the secrets of these artifacts, all while the political drama and power plays of Westeros continue.
One idea could be a scenario where the Vikings' raiding parties encounter the Night's Watch from Game of Thrones. Maybe they initially see each other as threats, but then realize they could be useful allies against the White Walkers. Another could be a story about a character from Vikings, like Ragnar Lothbrok, being magically transported to Westeros and having to navigate the complex politics there, similar to how he did in his own land.
Well, for a 'Game of Thrones Crossover Fanfic', a cool concept would be to cross it with 'Narnia'. The Starks could find themselves in Narnia and have to deal with the White Witch. Also, crossing it with 'The Hunger Games' would be interesting. Picture the different houses competing in the Hunger Games - style battles. And how about a crossover with 'Sherlock Holmes'? Sherlock could solve the mysteries in King's Landing.
Corvo Attano would be a great choice. His stealth skills and combat abilities would make him a formidable force in Westeros. He could easily blend into the shadows of King's Landing or any other city in the Seven Kingdoms. His ability to take down multiple enemies silently would give him an edge in the often - violent and politically charged situations in 'Game of Thrones'.
Another plot could involve a White Walker invasion in Skyrim. The Night King could lead his army through a magical portal that connects the two worlds. The people of Skyrim, including the various guilds, would have to team up with the houses of Westeros to fight this common enemy. The mages of Skyrim could share their knowledge of magic with the Red Priests and vice versa.
One idea could be exploring the backstory of a minor character from the game. For example, you could write about the life of a city watchman before the events of Dishonored 2. What made him join the watch? What has he witnessed in the city? Another idea is to create an alternate ending. Maybe in your fanfiction, Corvo and Emily work together in a different way to save the empire, leading to a completely new political landscape in Dunwall. And you could also focus on the relationship between the Outsider and other characters, like how his influence might have affected someone in a more positive or unexpected way.
In a 'Game of Thrones' and 'Sherlock' crossover, Sherlock's deductive skills could be used to solve the mysteries in Westeros. He could figure out who really poisoned Joffrey or find out the secrets of the Faceless Men. It would be interesting to see how his logical mind would interact with the more superstitious and political world of 'Game of Thrones'.
