One possibility is that in this fanfic, the female Harry Potter is somehow transported back in time and meets Morgan le Fay. Morgan le Fay could see the potential in her and decide to mentor her. So, Harry (or rather, the female version of him) starts learning magic in a completely different way than she did at Hogwarts. This new style of magic is more in line with the old, wild magic that Morgan le Fay was known for. She then has to balance her new knowledge with her old values from the modern wizarding world.
Well, it could be that the female Harry Potter discovers some ancient magic that has a connection to Morgan le Fay. Maybe she finds a hidden book or a magical artifact that links her to Morgan le Fay's powers. As she delves deeper, she starts to take on some of Morgan le Fay's characteristics, like her cunning and her knowledge of dark magic that can be used for good. She might also face opposition from the wizarding world who are afraid of her newfound powers and the influence of Morgan le Fay.
Perhaps the female Harry Potter is a reincarnation of Morgan le Fay without knowing it. As she grows older and her powers develop, she starts having strange dreams and visions of Morgan le Fay's life. These experiences lead her to explore more about Morgan le Fay. She could then find herself in a struggle between her own identity as Harry Potter and this new emerging identity as a sort of successor to Morgan le Fay. Along the way, she might have to fight against dark forces that are also interested in her connection to Morgan le Fay.
In terms of romantic relationships, if there was any budding romance for the female Harry Potter before, it would likely be affected. For example, if she had feelings for someone at Hogwarts, that person might be put off by her new transformation. On the other hand, she might attract new people who are interested in her new powers and the mystery surrounding her connection to Morgan le Fay. And her relationship with her enemies would become even more intense. Voldemort or his followers, if they're still in the story, would see her as an even greater threat or a potential ally, depending on how they perceive her new powers.
One possible plot twist could be that Morgan le Fay is not as evil as she seems in the original lore. Maybe she has a good reason for her actions in the past. When she marries Harry, she might be trying to use the union to protect the wizarding world from a greater threat that only she is aware of.
Well, perhaps the grandson of Harry Potter, being related to Le Fay, has some special abilities that set him apart from other wizards. The story could revolve around him trying to fit into the wizarding world while also dealing with the expectations that come with his unique heritage. He could be targeted by those who fear his potential power and he has to learn to control his abilities to protect himself and his loved ones. For example, he might discover that he has an innate talent for a type of magic that was long forgotten but is now resurfacing due to his connection to Le Fay.
It could be a new character introduced specifically for the fanfiction. Maybe a young witch or wizard who has been living in seclusion and discovers their heritage as the heir of Le Fay later on.
Yes, it could be considered in some ways. There are elements in the Harry Potter series that might show some inspiration from the concept of Lord Le Fay. For example, the magical worldbuilding and some of the magical elements might have been influenced by such related ideas. However, it's also a very unique and independent story with its own complex lore and characters.
It could be a group of dark wizards who want to use the grandson's connection to Le Fay for their own evil purposes. They might try to kidnap him or manipulate him to get access to the powerful magic associated with Le Fay.
One interesting plot point could be the exploration of the powers the heir of Le Fay might possess. Since Le Fay is associated with powerful magic, the heir might have unique spells or abilities that set them apart in the wizarding world. For example, they could have a deeper connection to nature - based magic than other wizards.
The story could also explore the reaction of the wizarding world to Harry's new heritage. Some might be afraid of him, thinking he could turn out like Morgana, who was often seen as an evil sorceress. Others, though, might see it as an opportunity to learn more about ancient magic that Morgana was known for.
Their relationship could lead to new magical teachings at Hogwarts. Morgan le Fay might introduce ancient spells and potions that were long forgotten. For example, she could bring in knowledge of dark magic defense that is more effective than what was previously taught.
Yes, there are quite a few. Some fanfics explore the relationship between Harry Potter and Lord Le Fay in really interesting ways. For example, there are those that imagine how their magical powers could interact in different scenarios, like in a hidden magical realm or during a special quest.
