The theme of loyalty could also be prominent. Arthur's loyalty to his kingdom and his knights might be tested against his loyalty to his love. He has to decide whether he will stand by his love in the face of opposition from his court or if he will side with his traditional allies and duties.
Saber from Fate/Stay Night would be an obvious choice. Since she is also related to the Arthurian legend, there could be a lot of interesting interactions between them. They could compare their experiences as king, or even fight side by side against a common enemy.
Arthur Pendragon might fall in love with a noblewoman from a neighboring kingdom. Their kingdoms have a long - standing alliance. They meet at a grand ball held to strengthen the bond between the two lands. Arthur is immediately drawn to her grace and intelligence. They start writing letters to each other when she returns to her kingdom. Their love blossoms through these letters, but political intrigues and power - hungry lords try to break their relationship apart as they fear the united front of the two kingdoms through their love.
One key element is the concept of courtly love. Arthur, as a king, was expected to show a certain refined and chaste form of love towards his queen, Guinevere. Another element is the conflict that love can bring. In his case, the conflict with Lancelot over Guinevere was a major part. Also, loyalty plays a role. Arthur's loyalty to his love and his kingdom were constantly being tested.
It's hard to say. Maybe it depends on your experiences and feelings. If you think there is, then there could be!
One possible reason could be a misunderstanding. Maybe Merlin did something that Arthur misinterpreted as betrayal or dishonesty. For example, if Merlin was secretly helping an enemy for a greater good that Arthur wasn't aware of at the time.
Another plotline could be a time - travel scenario. Draco gets sent back in time to Camelot. He becomes an apprentice or a follower of Arthur Pendragon. He then has to learn the ways of Arthur's court, deal with the politics and magic there, and in the process, he grows as a person, bringing back some of Arthur's wisdom to his own time when he eventually returns.
Well, it could start with a chance encounter. Maybe you're in a magical forest and Arthur Pendragon rides by on his horse. Your eyes meet and there's an instant spark. It's like something out of a fairy tale.
In Arthur Pendragon's love story, his love for Guinevere was deep. He chose her as his queen, seeing in her not only beauty but also a certain grace and charm. However, the presence of Lancelot, one of his most trusted knights, complicated things. Lancelot and Guinevere's love for each other grew, and when their affair was discovered, it sent shockwaves through Camelot. Arthur was faced with the difficult choice between his love for Guinevere and his loyalty to his kingdom and knights. This story shows how love can be both a powerful and a destructive force in the Arthurian world.
Maybe someone who is very creative and looks at the broad concept of magic in both. They could see the heroic aspects of Harry Potter and compare them to Arthur Pendragon's heroism. But really, it's a stretch. Harry Potter has a very different set of rules for magic and a different kind of society compared to the Arthurian world.
One common theme is gender role reversal. Since Arthur is typically male in the original legends, fanfictions with a female Arthur often explore how she navigates a world that has certain expectations for men. For example, she might face different challenges when it comes to leading knights or being accepted as a ruler.
