Sibling relationships within the Stark family, for example, are a major part of the plot. When the Starks are scattered, the bond between the siblings is a driving force. Arya's desire to avenge her family and Sansa's attempts to survive in King's Landing are related to their sibling ties. Their relationship gives them strength and a sense of purpose in the face of great adversity.
One of the most complex sibling relationships in the 'Game of Thrones' novel is between Cersei and Jaime Lannister. They are twins and have an incestuous relationship which greatly impacts the political and family dynamics in the story. Their relationship is both a source of power for the Lannister family at times and also a great source of shame and a ticking time - bomb that could destroy them all.
Daenerys and Drogo's relationship was different. Through her relationship with Drogo, Daenerys gained an army and started her journey towards power. Her sexual relationship with him was part of her initial step in building her own empire. She learned how to use her femininity and the power she had in that relationship to start amassing her own forces and influence.
An OC Stark might be more politically astute than the original characters. They could form different alliances, like making a deal with the Iron Bank that gives the North more financial power and influence. This would shift the power dynamics not only in the North but also across Westeros. The original plot of various houses vying for the Iron Throne would be affected as the North becomes a stronger and more independent force.
The incestuous relationship between Jaime and Cersei led to the birth of children that were not supposed to be in line for the throne. This caused a great deal of political turmoil. When their relationship was revealed, it also damaged the reputation of the Lannister family.
The geography plays a huge role. For instance, the Narrow Sea separates Westeros from Essos. This made it difficult for Daenerys to invade Westeros at first. It was a natural barrier she had to overcome.
They also influence character decisions. Take the story of the Mad King. Jaime's knowledge of his father's role in the downfall of the Mad King affects his relationship with his family and his own actions throughout the series. These internal stories shape the characters' beliefs and values, which in turn drive the main plot forward in different directions.
It can seriously damage the perception of family values. Family is seen as a place of safety and normalcy, and step - sibling sex stories introduce an abnormal and inappropriate element. It makes people question the integrity of family relationships.
In many Catelyn Stark time travel fanfictions, it can completely change the plot. For example, if she travels back and stops Ned from going to King's Landing, it would prevent a whole chain of tragic events. This is because Ned's presence in King's Landing was a catalyst for many power struggles and betrayals.
It would greatly affect the plot. It could shift the balance of power towards the Starks. They might be able to fend off threats more easily, like the White Walkers. The Starks could also use the dragon to intimidate their enemies, such as the Boltons or the Freys.
One of the notable sexual relationships is between Jaime and Cersei Lannister. Their incestuous relationship was a major plot point throughout the series. It was a complex and often disturbing relationship that had far - reaching consequences for the Lannister family and the power dynamics in King's Landing.
