If Rhaegar were to win in a 'Game of Thrones' fanfic, it would change the fates of many characters. For example, Ned Stark's life would be different. He wouldn't be on a quest for revenge against the Targaryens for his sister's supposed abduction. Instead, he might be serving under Rhaegar in some capacity, perhaps as an advisor or a military leader in the North. The Lannisters would also have to re - evaluate their position. Their plans for power might be thwarted as Rhaegar would be in control. Jaime Lannister might not become the Kingslayer in the same way, and Cersei's ambitions for the throne would be dashed. Overall, the power dynamics in Westeros would be completely reshaped with Rhaegar's victory.
If Rhaegar won in the 'Game of Thrones' fanfic, perhaps the Targaryen dynasty would be restored to its former glory. He might bring about a more just rule, with less bloodshed compared to the chaotic events that unfold in the original series. He could also potentially reunite the Seven Kingdoms under one banner more peacefully, using his charm and leadership skills.
The characters' fates would be drastically different. Daenerys might not have to go through all the hardships she faced in the original story as she could grow up in a more stable Targaryen - ruled Westeros. Tyrion could find himself in a court that values intelligence more, given Rhaegar's own intellectual pursuits.
If Rhaegar won in a 'Game of Thrones' fanfic, perhaps he could have restored the Targaryen dynasty to its former glory. He might have been able to bring about a more peaceful reign, with his love for music and the arts influencing the court. He could also have made different alliances, changing the political landscape of Westeros completely.
Well, if Rhaegar wins in this fanfic, Arya Stark could be a sort of diplomat for the North. Rhaegar would need to keep the North in line, and Arya, being a Stark, has the influence to do that. She might also befriend Rhaegar's family, like his sister or wife if he has one. Her journey could change from seeking revenge to building a new world under Rhaegar's rule. Maybe she'd even teach some of Rhaegar's men her unique skills, making them better fighters and spies.
If Rhaegar wins in the fanfic, Arya Stark's story arc would change drastically. Arya is a character defined by her quest for justice and revenge in the original story. But with Rhaegar in power, she may find herself in a different kind of fight. She could be drawn into the power struggle between Rhaegar and other potential claimants to the throne. Her skills as a faceless man would be valuable in this new political arena. She might also have to deal with the new social order that Rhaegar would establish. Her relationships with other characters would also be different. For instance, she may form an alliance with some of Rhaegar's supporters or be at odds with those who oppose his rule. This would all reshape her journey from a lone avenger to a key player in a complex political drama.
If Rhaegar was king in a fanfic, the story could be very different. He might have made different political decisions. For example, he could have tried to reform the system more peacefully. He was known for his love of music and books, so perhaps he would have promoted the arts more in the Seven Kingdoms.
If Robb won the war in a fanfic, it could lead to a completely different Westeros. He might establish a more just rule in the North and perhaps even expand his influence over other kingdoms. Maybe he'd form new alliances and bring about an era of peace and prosperity, unlike the chaos that followed in the original series.
In the Game of Thrones universe, Rhaegar and Lyanna's story is a tragic and complex one. Rhaegar was a complex character, often misunderstood. He was drawn to Lyanna for reasons that may have been related to his understanding of certain prophecies. When he took Lyanna, it sparked a war. The Starks, led by Lyanna's brother Brandon, felt they had to rescue her. This led to Brandon's death at the hands of the Mad King, Aerys II. The war that ensued, Robert's Rebellion, changed the political landscape of Westeros forever. And all because of the relationship between Rhaegar and Lyanna, which also had the unforeseen consequence of Jon Snow's birth, a character who would play a crucial role in the later events of the series.
If Rhaegar was king in a fanfic during the War of the Five Kings, he could have prevented it. His leadership might have been strong enough to keep the lords in line. He would have had the power to resolve disputes before they escalated into full - blown war.
It would change the storyline drastically. For one, many characters who died in the original story might survive. Robb's victory could mean a different fate for Sansa and Arya, as he would have more power to protect his family. Also, the political landscape would be very different. The Lannisters would be in a much weaker position, and that would affect how they interact with other houses.
