There is no official information about the Sisters Black in the original Harry Potter series. So they are likely to be characters created specifically for this side - story concept. They could be a group of witches with their own unique personalities and magical powers.
Well, obviously Harry Potter is one of the main characters. And then there are the Sisters Black. We don't know much about them yet, but they are likely to be witches with their own personalities, powers, and backstories that will be explored in the fanfic.
A great fanfiction in this genre could be one that reimagines the Black Sisters' past and how they interacted with other characters in a more adult - themed way. For example, it could show how Bellatrix's loyalty to Voldemort might be in conflict with her sisterly bonds. The lemon aspect could come into play when exploring their romantic or sexual relationships that might have been hidden or taboo in the original story. It's all about exploring new dimensions of these well - known characters.
One way to find suitable 'Harry Potter Black Sisters' fanfic is to ask in Harry Potter fan communities. Reddit has some great Harry Potter sub - forums where fans discuss and recommend fanfics. They can point you towards fanfics that are more about the sisters' character development, their role in the wizarding society, and their bonds with each other, without any lemon content.
Another possible plotline is that the Sisters Black are outsiders in the wizarding world due to their family's reputation. But they meet Harry, who also has a bit of an outsider status in some ways. Together, they try to change the perception of their families in the wizarding community while also dealing with the normal Hogwarts adventures like Quidditch, classes, and the Forbidden Forest.
Another plotline could be their connection to the wider wizarding war. Maybe they have some secret knowledge or a role to play that was not fully explored in the original books. They could be involved in some behind - the - scenes operations during the war, either on the side of the Order of the Phoenix or Voldemort's forces in a more complex way than just being simple followers.
Well, the Black Sisters in Harry Potter fanfiction are Bellatrix, Narcissa, and Andromeda. Bellatrix is a really dark character, always causing trouble in the name of Voldemort. Narcissa, she's kind of in the middle. She wants to protect her family but is also part of the pure - blood mania in the Black family to some extent. Andromeda is different. She breaks away from the family's more evil - inclined traditions. Fanfic authors use these sisters to show different perspectives within the wizarding world.
The Black sisters' roles in Harry Potter fanfiction are diverse. Bellatrix is the main antagonist among them, her actions causing chaos and destruction. Fanfics might focus on her backstory to explain her actions better. Narcissa, she may act as a double - agent in some stories, using her position in the Black family to gather information for the good side. Andromeda, being the sister who left the family for love, can be a source of inspiration for characters in the fanfiction. Her story of breaking free from the pure - blood - only ideology can be told in more detail, showing how she overcame the obstacles and built a new life.
Well, in Harry Potter fanfiction about the Black sisters, Bellatrix is usually depicted as the most deranged one. Her obsession with Voldemort is a central aspect of her character. Narcissa is sometimes presented as a conflicted character, torn between the dark side she was born into and her motherly instincts. Andromeda, being the outcast, can be the subject of stories that show her strength in defying the Black family's pure - blood ideology. Fanfiction can really expand on their personalities and the dynamics between them, making them even more interesting than in the original books.
