A unique plot that either fills in gaps or takes the story in a new direction. Like exploring what would have happened if a certain character didn't die. It has to be something that the original series didn't cover but still feels like it could be part of the same universe. It should also have a good flow and pacing, not be too rushed or too slow.
Accurate use of the existing lore is also important. If it respects the rules of the world of Westeros, such as the politics, the magic system, and the relationships between the houses. Fanfictions that do this well can create a more immersive experience for the readers, making them feel like they are still in the Game of Thrones world but just seeing a different side of it.
One of the great ones could be 'A Song of Ice and Fire: The Lost Chapters'. It fills in some of the gaps in the original story in a really engaging way. It has well - developed characters and a plot that weaves in and out of the existing lore seamlessly.
The 'forbidden love' trope can be really engaging. Imagine a love story between a character from 'Game of Thrones' and one from 'Lord of the Rings' in a crossover fanfiction. This trope can create a lot of conflict and emotional depth. And the 'rag - to - riches' or 'rise to power' trope is also seen a lot, as it shows the character's growth and transformation.
It has a complex web of characters and a richly detailed world. The political intrigue and unexpected plot twists keep readers hooked.
Redemption is also a theme that pops up a lot. Some characters in fanfic might be seeking redemption for their past wrongs. This could be a knight who has killed innocents in the past trying to make amends, or a lord who has betrayed his people and now wants to set things right. It's an interesting way to explore the moral grey areas of the 'Game of Thrones' universe.
The 'romance' trope is also quite common. Fans often create stories that focus on romantic relationships between characters that were not explored in the show, or they expand on the hinted romances. For instance, there could be a detailed story about Jon Snow and Daenerys Targaryen's relationship if you're into that pairing.
In this kind of fanfiction, a common trope is the 'power transfer'. This could be a magical item from The Hobbit having an impact on the power dynamics in Game of Thrones. Also, the 'lost heir' trope is popular. Maybe a character in Middle - earth is revealed to be related to a noble house in Westeros. There are also 'redemption arcs' where a villainous character from one universe gets a chance to redeem themselves in the other universe's setting.
One popular trope is the 'fish out of water' story. For example, a character from Game of Thrones suddenly appears in the Warcraft world and has to adapt to its strange new rules, magic, and races. Another is the 'power - up' trope. A relatively weak character from either universe gains extraordinary power in the other universe's context. For instance, a peasant from Game of Thrones might discover they have a natural affinity for Warcraft's shamanistic magic and become a powerful force.
The 'fish - out - of - water' trope is also prevalent. The male SI, coming from a modern world, has to adjust to the medieval - like setting of 'Game of Thrones'. This can result in humorous situations as they struggle with the different customs and values. But at the same time, it also allows for character growth as they learn to adapt and thrive in this new and dangerous world.
One popular trope is the 'fish out of water' story. For example, a Viking suddenly finding themselves in the complex political world of Game of Thrones. Another is the power - hungry character from one universe trying to take over in the other. It adds an element of conflict and drama.
A less common but still present trope is the 'Mentor - Student' relationship. An elf, with their long - lived wisdom and magical knowledge, could become a mentor to a young character in Game of Thrones, like Arya Stark. The elf teaches the human skills, whether it's combat - related magic or a different way of thinking, which then helps the human character in their own journey and development within the story.
