There's also 'Horcrux Hunt: The Unseen Bond' which delves deep into the relationship between Harry and Hermione during their search. It has some really creative interpretations of how they overcome the obstacles related to the Horcruxes. In this fanfiction, they face not only the danger of the Horcruxes themselves but also the political unrest in the wizarding world at the same time. Their friendship is put to the test and grows stronger as they progress in their hunt.
One common theme is the growth of their relationship. As they hunt for Horcruxes together, their bond deepens whether it's a platonic friendship or something more in some interpretations.
The Horcrux hunt with Harry, Fleur, and Tonks in fanfiction could be full of adventure. Harry has his own experience and determination. Fleur could add an element of mystery and allure. Tonks, with her unique magic, is quite a valuable asset. They could start by researching the possible locations of Horcruxes in old wizarding libraries. Fleur might be able to charm the librarians into giving them more access. Tonks could change her appearance to look like a different wizarding scholar. Harry would be constantly on the lookout for any signs related to Voldemort. Their journey would be filled with close calls and unexpected allies.
Well, a possible plotline is that they discover a Horcrux in a place that was previously thought to be just a mythical or lost location. Maybe it's hidden in an ancient wizarding ruin that has been long forgotten. As they search for this Horcrux, they encounter all kinds of magical creatures and traps. And also, their relationship might develop romantically during the hunt. They share moments of fear and triumph which bring them closer together.
The main characters are obviously Harry and Daphne. Harry, being the Boy Who Lived, has a lot of experience with fighting Voldemort and is determined to destroy all the Horcruxes. Daphne, on the other hand, is likely a Slytherin or has some connection to Slytherin. She brings her own set of skills and knowledge to the Horcrux hunt. Maybe she has a good understanding of dark magic or some family secrets that can be useful.
Well, there's 'Harry and the Horcrux Legacy'. In this fanfiction, Harry not only has to deal with the existing Horcruxes but also some new threats related to the Horcrux magic. It's really engaging as it combines the familiar elements of the Horcrux concept from the books with new adventures for Harry. There's also 'Horcrux Redemption' which has an interesting take on how the Horcruxes could potentially be redeemed rather than just destroyed.
In many fanfiction works, Hermione being a Horcrux is a fascinating concept. It gives a whole new dimension to the story. By making Hermione a Horcrux, it creates a complex situation. The other characters would have to deal with the fact that she is not only their friend but also a container of a part of Voldemort's soul. This could change the dynamics of their relationships. It also opens up possibilities for new magical solutions to defeat Voldemort, as they would have to find a way to destroy the Horcrux within Hermione without harming her.
One idea could be that the character discovers a hidden Horcrux in a place no one expected, like in an old, abandoned wizarding prison. They have to face numerous dark magic traps alone. Another could be that they are being hunted themselves while on the Horcrux hunt, adding an extra layer of danger.
In some fanfictions, Draco might use his knowledge of the Dark Arts and Hogwarts' secrets. Since he was raised in a Death Eater family, he could have insights into how Voldemort might have hidden the Horcruxes. For example, he might know of certain places within the school that Voldemort frequented or had an interest in.
Their relationship could start with hostility. Draco has been an enemy to Harry for a long time. But during the Horcrux hunt, they might find common ground. For instance, they both want to stop Voldemort, even if their reasons are different. This common goal could lead to a grudging respect. Harry might see that Draco isn't all bad, and Draco might see Harry as more than just the 'Chosen One' he resented.
Another plot could involve Draco actually knowing some secrets about the Horcruxes that he initially doesn't want to share with Harry. But as the danger of Voldemort's power growing becomes more and more real, he realizes he has to help. So, during the hunt, Draco gradually reveals bits of information that he has, which helps Harry in unexpected ways. This could lead to a redemption arc for Draco, as he goes from being on the side of the Death Eaters in a way to actively working against Voldemort by assisting Harry.
