A possible idea is to have a character like Daenerys Targaryen receive visions similar to those in the Bible. These visions could guide her in her quest for the Iron Throne, but also make her question her actions and power-hungry nature. It would be an interesting take on her character development.
One could write a fanfiction where a group of characters form a sort of 'Christian - like' community in Westeros. They practice values such as love, kindness, and sharing, which are in contrast to the general cut - throat nature of the world. Their presence could start to influence other characters and change the political and social landscape of the Seven Kingdoms.
Imagine a fanfiction where the White Walkers are seen as a form of 'evil' that can only be defeated through a combination of physical strength and spiritual means inspired by Christianity. The characters might need to find a way to come together and embrace values like unity and faith in a higher power to combat this great threat, much like how religious faith can be a source of strength in facing difficulties in real - life Christian teachings.
One idea could be exploring what would happen if a minor character, like Gendry, had a more prominent role in the story. He could potentially become a powerful lord and change the political landscape.
A great idea for 'Game of Thrones fanfiction' is to rewrite the story from the perspective of the smallfolk. For instance, how did they really feel during all the wars and power struggles? How did the common people in King's Landing cope with the different rulers? You could also explore a fanfiction where the White Walkers are not the villains. What if there was a misunderstanding and they were actually trying to protect the realm from some other greater threat?
One idea could be exploring what would happen if Jon Snow was raised by the Starks as a trueborn son. Another could be a fanfiction about Daenerys Targaryen's journey if she had made different alliances earlier. Or perhaps a story about Arya Stark training with a different master assassin.
One idea could be exploring what would happen if a minor character like Gendry had been secretly trained in magic. He could use his newfound powers to unite the smallfolk against the warring nobles. Another plot could revolve around a female knight from the North who disguises herself as a man to fight in the wars, and along the way, she discovers secrets about the White Walkers that no one else knows. Or perhaps a fanfiction where Daenerys and Sansa form an alliance much earlier and together they reshape the power dynamics of Westeros.
One way they can be combined is through exploring the themes of morality. In 'Game of Thrones', there are complex moral situations, much like in Christianity where moral teachings are central. For example, a fanfiction could focus on a character like Jon Snow and draw parallels to the Christian concept of sacrifice. Jon Snow often makes selfless decisions for the greater good, similar to the sacrifice of Jesus in the Christian faith.
A cool fanfiction concept could be a situation where the magic in Game of Thrones has an impact on Smallville. Suppose a powerful sorcerer from Westeros accidentally opens a portal to Smallville. This could lead to all kinds of chaos as the residents of Smallville have to deal with magic they've never seen before. On the flip side, the Kryptonians' powers could be seen as a threat in the eyes of the Game of Thrones characters, leading to a potential conflict. Or perhaps some of the noble houses in Westeros could try to form alliances with the powerful beings in Smallville for their own political gain.
One idea could be a story where a character from 'Game of Thrones' is transported into the world of 'For Honor' and has to adapt to its combat styles. For example, Jon Snow finding himself in the middle of a battle in 'For Honor' and using his skills to survive. He might form alliances with the different factions in the game, much like he did in Westeros.
An interesting 'oc game of thrones fanfiction' could focus on an OC who is a female knight in a world dominated by male warriors. She could face discrimination but also prove herself in tournaments and battles. Maybe she becomes a trusted ally of a major character like Jon Snow. Or you could have an OC who is a bard that spreads tales which either inspire or deceive the people of Westeros. Also, an OC who is a foreign diplomat trying to broker peace deals between the warring factions while having their own hidden agenda would be a great concept.
One idea could be Loki somehow being transported to the world of Game of Thrones and using his magic to manipulate the political intrigue. He might side with a particular house and use his wits to outsmart their enemies.
One idea could be to combine the magic systems. For example, in Warhammer there are powerful spells and in Game of Thrones there is magic like that of the Red Priests. You could have a character who is a hybrid of a Warhammer wizard and a Game of Thrones maegi, creating new and unique magical abilities and storylines. Another idea is to merge the political intrigue. The complex power struggles in Game of Thrones and the different factions in Warhammer could lead to some really intense and convoluted political plots. For instance, the different Chaos factions could be like the different Houses in Westeros, all vying for control and power.
