One plot idea could be that Hermione discovers a hidden mark left by Greyback that has some sort of magical connection. Maybe it gives her insights into his past or his pack's secrets. Another could be a story where Hermione has to find a way to break the mark's hold on her or someone else it's affecting.
Well, perhaps the mark burn is a symbol of a curse that Greyback placed on Hermione. The fanfiction could explore how she tries to reverse it with her intelligence and magic skills. She might seek help from her friends, like Harry and Ron, and they embark on a journey to find ancient spells or artifacts that can undo the mark burn. It could also involve a lot of internal struggle for Hermione as she battles the dark influence of the mark.
Hermione would initially be shocked and a bit scared. After all, anything related to Greyback is not good. However, being the strong - willed witch she is, she would quickly start researching in the library, looking for any information about the mark burn. She might also try some basic diagnostic spells to figure out what exactly the mark is doing to her or if it's spreading some sort of dark magic. She would be cautious around others, not wanting to put them in danger if the mark has some contagious or harmful effect.
A possible plot could be that Hermione gets bitten by Greyback accidentally. Instead of turning into a full - blown werewolf, she has some new abilities and a strange connection to Greyback. They then have to figure out how to deal with this new situation, while also facing the wizarding world's prejudice against werewolves. It could also involve Hermione using her intelligence to find a cure for herself and in the process, changing Greyback's view of non - werewolves.
One idea could be that Fenrir Greyback, instead of being a full - on villain, has some sort of complex relationship with Hermione. Maybe he's forced to protect her in a situation where they are both in danger from a greater dark force. This could lead to a lot of tension and moral dilemmas for Hermione as she has to deal with being around a werewolf who has a reputation for being cruel.
One plot idea could be that Fenrir Greyback, instead of attacking Hermione, is somehow magically bound to protect her. This could lead to a strange alliance where Hermione has to trust a werewolf known for his brutality. Another idea is that Fenrir has a change of heart due to Hermione's intelligence and courage, and he starts to fight against his dark nature for her sake. Maybe he could help Hermione in a battle against the Death Eaters by using his werewolf strength in unexpected ways.
A plot could revolve around Hermione being kidnapped by Greyback's pack. But instead of succumbing to fear, she uses her intelligence to gain the respect of some of the werewolves. Greyback is initially hostile but gradually becomes intrigued by her. Their relationship could then develop as Hermione tries to broker peace between the werewolves and the wizarding community. Maybe there's a prophecy involved that says only their union can bring peace, and they have to navigate the complex emotions and politics around it.
One plot idea could be that Draco discovers Hermione has a connection to the Dark Mark against her will. Maybe she was cursed with it during an encounter with Death Eaters. Draco, having some knowledge of the Dark Arts, decides to help her get rid of it secretly, which would lead to many tense and secretive meetings between them as they try to figure out how to break the curse without getting caught by either side.
In one fanfiction concept, Greyback saves Hermione when she is trapped in a magical maze created by dark wizards. Greyback, being a cunning and experienced dark creature, is able to navigate the maze and get to Hermione before the maze collapses or she is killed by the various traps inside. He might save her because he senses that she has a great potential that could be useful to him in the future.
A really interesting plot could be set in an alternate universe where Fenrir Greyback was once a normal wizard but was turned into a werewolf by dark magic. Harry Potter, through some magical accident, finds himself in Greyback's past and tries to prevent his transformation, which would change the course of the entire wizarding world as they know it.
Another storyline might involve a time - travel scenario where Hermione goes back in time and encounters a younger Fenrir Greyback. She attempts to change his path, to prevent him from becoming the cruel werewolf he is known to be in the future. This could involve her using her knowledge and magic to offer him a different future, but facing many challenges along the way.
It's interesting because it takes two characters from very different 'sides' in the Harry Potter universe. Hermione is one of the main protagonists, and Greyback is associated with the dark forces. When you put them in a situation where he protects her, it can lead to a lot of complex character interactions and plot developments. For example, it could explore themes of redemption for Greyback or a new understanding between the two different 'worlds' they represent. It also allows for creative interpretations of their personalities and backstories that we might not have considered before.
