The birth could also create tension. Some houses in the North that were reluctantly following Sansa might see the new heir as a threat to their own local power. They might start to scheme and plot against Sansa and her child. On the other hand, some of the more progressive houses could see this as an opportunity to reform the North, perhaps by introducing new laws and systems to ensure the smooth succession of power from Sansa to her child.
If Sansa gives birth, it could solidify her claim to power in the North. A new heir means a continuation of her line, which would make it harder for any rival houses to try and usurp her position. Other regions might also view her differently. For instance, the Vale which has been an ally might become even more closely tied to the North. They could see the new heir as a way to further their own influence in the future of Westeros through marriage alliances.
She could be a key figure in uniting the Seven Kingdoms under a new form of government. Instead of the traditional monarchy, she might propose a council - based system where each kingdom has a representative. Her diplomatic skills and her family name would give her the credibility to bring all the kingdoms to the table and discuss such a major change.
Perhaps Sansa's child is fathered by a character who is not a traditional choice. This could lead to all sorts of political intrigue and family drama. For example, if the father is from a formerly enemy house, it could force a re - evaluation of alliances in Westeros. The birth itself could be a difficult and dangerous process, with Sansa having to fight off those who would try to harm her or the unborn child during her pregnancy.
The powers of the X - Men would have a huge impact. For instance, Jean Grey's telekinetic and telepathic powers. She could easily manipulate the minds of the lords and ladies, making them vote or act in a certain way. This would completely disrupt the normal political intrigue and power plays that are based on alliances and manipulation through words and gold. It could lead to a new form of rule where those with the most powerful mutants are in control.
The Lich King could be a major disruptor. He doesn't care about the normal politics of the Iron Throne or the houses. He would likely try to use the political chaos to his advantage. For example, he could support one side in a war just to create more death and destruction, which he can then use to raise more undead soldiers.
Gunpowder can change the political landscape by giving an edge to those who possess it. For instance, a minor house with gunpowder can threaten larger houses and demand concessions. It could lead to new alliances being formed as houses seek protection from or access to gunpowder. Also, it might make traditional military strategies obsolete, forcing lords to rethink how they defend their lands.
It develops in various ways. Sometimes, it starts with the Hound's initial gruffness towards Sansa, but as time passes, he starts to see her as more than just a Stark girl. Sansa, on her part, might begin to understand the Hound's pain and his reasons for his actions.
Their relationship could also develop in a more complex way where Sansa starts to play Littlefinger at his own game. She may start to use his own tactics of manipulation against him, leading to a shift in the power dynamic between them. It could be like a cat - and - mouse game where Sansa is slowly turning the tables on Littlefinger.
Often, Sansa is portrayed as a powerful figure in fanfiction, and Jaime's character can add an interesting dynamic. They might be shown as having conversations that never occurred in the show. For example, Jaime could offer Sansa his insights about the political situation in King's Landing, which she could use to her advantage in her own political maneuvers in the North.
In fanfiction, Sansa's development can be greatly influenced by Sandor. She may start to question the traditional ideals of beauty and chivalry that she once held dear, seeing the realness in Sandor. Sandor himself could develop a sense of purpose beyond just being a fighter. Their interactions could be the catalyst for these changes. For instance, Sansa might encourage Sandor to use his strength for more noble causes, and in turn, Sandor could help Sansa find her true voice in a world that has silenced her for so long.
In fanfiction, Sansa's strength lies in her ability to adapt and endure. She has been through so much in King's Landing and has come out stronger. Her character development is often about becoming a shrewd leader in the North. Daenerys, though, is shown as having this inborn sense of entitlement to the throne. Her power is more flamboyant with her dragons and her army. They are different in their approaches to leadership, and this is clearly shown in the way they are written in fanfictions.
