The relationship between Robb and Talisa in fanfiction can also be a source of great emotional drama. Their love could be tested by war, betrayal, and family obligations. Fanwriters might write about their private moments of joy and sorrow, how they comforted each other during difficult times, and how their love endured or, in some cases, tragically ended.
A sense of adventure is also present. They were in the middle of a war - torn Westeros. Fanfictions might take them on different adventures together, away from the main battles, or they could be involved in secret missions that test their relationship. Also, the theme of loyalty, both to each other and to their respective causes, is explored. How they balance their loyalty to each other with their loyalty to their families and kingdoms is a rich area for fanfiction writers.
I recommend 'Robb Stark: The Lost Legacy'. This fanfiction focuses on an alternate timeline where Robb survives. It's interesting as it explores how he would have changed the course of the story. It has some great character development and interactions with other key characters from the series.
Another reason is that Robb Stark's story ended tragically in the original series. Fans are drawn to fanfiction as a way to rewrite his story, give him a better ending, or just see different interpretations of his character. It allows for a lot of creativity and speculation among fans.
One great 'Game of Thrones Robb Stark OC fanfiction' is 'The Stark Heir'. It follows an original character who becomes an important ally to Robb Stark. The story has great character development and exciting battle scenes.
One possible plot could be that Robb Stark manages to avoid the Red Wedding trap. Maybe he receives a tip - off from an unexpected source, like a disgruntled Frey servant. With this knowledge, he could turn the tables on his enemies. He might use his military strategy skills to ambush the Freys instead, and this could lead to a major shift in the power dynamics in the North, with Robb emerging as an even stronger leader.
One interesting 'Game of Thrones Talisa fanfiction' could be about her having a secret mission before she met Robb Stark. Maybe she was sent by a hidden group to influence the events in the North. In some fanfictions, she might have special powers that she has to keep hidden in order to fit into the world of Westeros.
First, do your research on Robb Stark's character. Know his traits, his goals, and his relationships in the original series. Then, create your original character with a clear backstory, personality, and motivation. Make sure the OC's story can fit into the world of Game of Thrones. For example, if your OC is a warrior, think about where they learned their skills and why they would side with Robb Stark.
It could change it a great deal. In the original story, Robb's actions regarding the Freys led to the Red Wedding. But if he married a Frey, it would mean no Red Wedding. This would keep Robb alive and his army intact. It could also change the power dynamics in Westeros as the Stark - Frey alliance would be very strong.
Fanfiction delves into Robb Stark's smartness in multiple aspects. His intelligence can be portrayed in his ability to learn from his mistakes. In some stories, after a defeat or a setback, he analyzes what went wrong and comes up with a new and better plan. His smart side is also shown in his interactions with different characters. He might be able to sense the true intentions of those around him, be it friends or foes. For example, he could see through the false loyalty of a bannerman or recognize the value of an unexpected ally. This way, fanfiction expands on the character of Robb Stark as a smart and capable leader.
Realistically, their relationship would be influenced by the political situation around them. Since Robb is a king in his own right and Roslin is part of a powerful family, their union is as much political as it is personal. They need to navigate the political intrigues together. For example, they might have to deal with jealous lords who oppose their relationship. Roslin could use her diplomatic skills to win over some of the doubters, while Robb protects her from those who would do her harm. Their relationship would also be shaped by the small moments of kindness and understanding between them. A simple gesture like Robb bringing Roslin a flower from the battlefield or Roslin making a warm cloak for Robb during the cold winter months can gradually build their love.
