In some cases, the common people could be antagonists. They are used to the traditional divide between the Starks and the Lannisters. If Cersei and Ned's marriage brings about new laws or policies that they don't like, they could rise up against them. Also, the fanatic followers of the Faith of the Seven might oppose the marriage if they see it as against their religious beliefs or moral code.
The Lannisters, apart from Cersei, could be antagonists. Jaime might see Ned as a threat to his relationship with Cersei and try to undermine the marriage. Tywin Lannister could also be against it as he has his own political plans that don't involve Cersei being married to a Stark. He might try to find ways to dissolve the union.
The other lords and ladies in King's Landing who oppose the idea of a Lannister - Stark alliance could be antagonists. They might fear the new power dynamic that Cersei and Ned's marriage would create. For example, the Boltons could see it as a threat to their own ambitions in the North, and the Tyrells might not want to lose their influence in the capital if Cersei and Ned become too powerful together.
Well, if Ned married Cersei, it might have changed the course of many events. Their opposing natures and loyalties could have caused chaos within the realm. It could also have affected the relationships of other characters in unexpected ways.
The main characters are clearly Cersei and Ned. Cersei, a complex and often conniving character from the original story, and Ned, known for his honor and sense of duty.
One possible plot could be a political alliance that forms between Cersei and Ned. They might initially be at odds but gradually come to respect each other's political acumen. They could work together to fend off common enemies in King's Landing, and in the process, their relationship could develop into a complex mix of friendship and something more, with both having to navigate the tricky waters of loyalty to their respective houses.
It could have led to a very different power dynamic in Westeros. Maybe Ned's honor and Cersei's ambition would have clashed constantly.
Well, it would be a very different story. Their marriage might force the Starks and Lannisters to work together more closely. But Ned would be constantly aware of Cersei's true nature. He might try to keep her in check, which would make her resent him. And the whole Robert's Rebellion backstory would have a different feel. Since Ned was so close to Robert, his marriage to Cersei would add a strange layer of complexity to that relationship. It could also potentially change the fates of their children, as they would be part of a combined Stark - Lannister family.
The challenges would be many. Politically, their marriage would be a strange alliance. The Starks and Lannisters have different agendas. Ned would want to rule justly and fairly, while Cersei is only interested in power for herself and her family. Emotionally, they are polar opposites. Ned is a loving father and a man of principle. Cersei is a complex character, often driven by jealousy and greed. Her relationship with Jaime is a major hurdle. And Ned would have a hard time trusting Cersei, given her reputation for underhandedness. Their marriage would be like mixing oil and water in the world of fanfiction.
One common antagonist could be an old enemy of Artemis who doesn't approve of her marrying Percy. This enemy might be a powerful Titan who sees their union as a threat to his plans for revenge against the gods.
The Sith Order could be one of the main antagonists. They might see Vader's marriage to Padme as a weakness or a deviation from the Sith path. So they could try to undermine their relationship or even harm Padme to bring Vader back to their full control.
Political intrigue is often a part of ned x cersei fanfiction. Their positions in the original series make it so that any relationship between them would be intertwined with the political landscape. Writers might create scenarios where they have to navigate through political plots together or against each other, which makes for a very engaging read as it combines the personal relationship aspect with the high - stakes world of politics.
Common themes in 'Cersei x Ned fanfiction' include 'trust and betrayal'. Since they are from different factions originally, the idea of building trust or dealing with betrayal is often explored. 'Survival' is also a theme. In some fan - made stories, they have to rely on each other to survive in a dangerous political climate. And 'family loyalty' can play a part too, as both characters have strong family ties that can either bring them closer or drive them apart in the fictional relationship.
