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, one way could be through magic. Maybe there's a powerful spell that creates a portal between Draco's magical world (say the wizarding world of Harry Potter) and Arthur Pendragon's Camelot. Through this portal, characters from both worlds can interact, and their cultures and magic systems start to blend. For example, wizards from Draco's world might introduce new spells to Camelot, while Arthur's knights could teach the wizards about chivalry.
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.
One great Arthur Pendragon hurt fanfiction is 'The Wounded King' which delves into his emotional turmoil after a major battle. It shows his struggle to regain his strength both physically and mentally.
Well, in such a fanfiction, they could team up against a common enemy. Maybe an ancient dark force that has been awakened in both their times. Their combined knowledge of magic from different eras would be a great asset.
A fanfiction that stands out is 'Arthur and Merlin: A Different Path'. This one takes a different turn from the original storyline. It imagines a world where Arthur discovers Merlin's magic much earlier. This changes the whole dynamic between them, and they face different challenges together. There is also 'The Adventures of Merlin and Arthur in the Enchanted Forest'. It's full of exciting quests and the development of their friendship.
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 possibility is a story where a vampire in The Vampire Diaries discovers an ancient relic related to Arthur Pendragon. This leads to a journey through time where they end up in Camelot. There, they face the challenges of Arthur's court, and perhaps a vampire falls in love with one of Arthur's knights or a lady in waiting. It would be a story full of adventure, romance, and the clash of two very different worlds.
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.
One possibility in Hermione and Arthur Pendragon fanfiction could be a story where Hermione uses her modern magical knowledge to help Arthur Pendragon in his time. For example, she could introduce new spells or ways of using magic that were not known in his era. This could lead to a series of adventures as they face challenges together, like defending Camelot from a new dark magic threat.
