Fanfiction about Harry Potter and Fleur's sister: What could be the possible plotlines?

One possible plotline could be that Lemon, as Harry's older sister, discovers her own magical abilities earlier than Harry. She could be a bit of a rebel, exploring the wizarding world in her own way, perhaps getting into trouble with the Ministry of Magic for her unorthodox ways of using magic. She might also be protective of Harry, using her more advanced magical skills to shield him from some of the early threats that he faced in the books, like Draco's taunts at Diagon Alley.

Another idea for a fanfiction could be that Fleur Delacour's sister is a powerful witch in her own right but has a completely different approach to magic. While Fleur is all about grace and charm in her magic, her sister might be more into dark arts - not in an evil way, but in a way of studying it to understand how to combat it better. She could end up teaming up with the Trio (Harry, Ron, and Hermione) to fight against a new dark wizard threat at Hogwarts.

In one plotline, Fleur could be the target of a curse that slowly drains her magic. Harry, as her bodyguard, has to find a way to break the curse while keeping her safe from those who might want to take advantage of her weakened state. This could involve seeking out ancient spells and potions, and they might have to journey to dangerous and mysterious places. As they do so, their relationship could evolve from Harry simply being a protector to someone Fleur deeply trusts and relies on, and there could be hints of a romantic connection developing between them.

One possible plotline could be that it's set after the war. Harry and Fleur find solace in each other's company. They might be sitting by the fireplace in the Burrow, and as they cuddle, they share stories of their past traumas. Fleur could talk about how difficult it was for her being part - Veela during the war, with people being both attracted and distrustful of her. Harry, in turn, would open up about his experiences with Voldemort. Their cuddling becomes a source of comfort and a sign of a new beginning for both of them.

One possible plotline could be that Harry's half - sister is initially on the side of the dark forces. She could be manipulated by Voldemort or his followers. Harry then has to try and save her and turn her to the good side. This would be a classic good - vs - evil struggle within the family.

Another plot could involve a sort of magical exchange. Orochimaru, being a master of some dark and strange jutsu in his own world, might offer to teach some of his knowledge to certain dark wizards in the Harry Potter world in exchange for something valuable. Harry Potter and his friends would have to prevent this knowledge transfer as it could tip the balance of power towards the dark side in their world. They might need to seek help from some of the more powerful and wise wizards like Dumbledore to outwit Orochimaru.

Another plot could involve Medusa being a part of a long - forgotten magical mystery that is somehow related to Harry's destiny. Harry, with his inquisitive nature, starts to research about her. As he gets closer to the truth, he has to face the danger of being turned to stone. But through his courage and the help of his friends, he manages to break the curse on Medusa, and in return, she helps him in his fight against Voldemort.

Well, there could be a plotline where Snape's father was an inventor in the wizarding world. He might have created some powerful magic items or spells that were lost or forgotten. Snape, in the fanfiction, could be on a quest to find and revive his father's work. Another idea is that Snape's father was a key figure in a war long before Voldemort's rise, and his actions had consequences that Snape has to deal with in the present day of the fanfiction. There could also be a plotline where Snape's father was a mentor to some other important character, and this connection has implications for Snape's life and the overall story.

One possible plotline could be that Uncle Matthew Potter has some long - lost magical power or artifact that the main characters need to find. This could lead them on an adventure through different parts of the wizarding world. Another plot could involve him having a secret connection to a dark wizard from the past, and the story could be about uncovering this connection and dealing with its consequences.

Perhaps the twin sister has a special power or ability that Draco initially wants to use for his own gain. He tries to befriend her under false pretenses. But as he gets to know her better, he realizes she's not just a means to an end. For example, if she has the power to communicate with magical creatures, Draco, who is interested in the more elite aspects of the wizarding world, might see this as an opportunity to impress his family. However, as he spends time with her, he starts to care about her for who she is, and they develop a relationship that goes against the expectations of their respective friend groups and families.
