The domination of Harry Potter in such fanfiction can attract more readers. Since Harry is so popular, fans who love Harry are more likely to read fanfictions where he is the dominant character. This can then expose more people to Narcissa as a character, and potentially increase the overall interest in fanfictions that involve her, even if the initial draw is Harry.
A possible plotline could be that Harry, after the war, is magically bound to Narcissa for some reason. In the harem setting, other characters like Luna or Ginny could also be part of it. Harry has to figure out how to balance his relationships while also dealing with the post - war wizarding world. Narcissa might use her influence to protect Harry from those who still hold grudges against him.
One possible plotline could be that Narcissa tries to keep her pregnancy a secret from Voldemort, fearing his reaction. Another is that she uses her pregnancy as a reason to distance the Malfoy family from the Dark Lord's side.
In fanfiction, the Harry Potter language lozenges might have the effect of allowing the user to speak different magical languages fluently. For example, it could enable one to understand and communicate in Parseltongue without being a Parselmouth. This could lead to all sorts of interesting plot developments, like being able to decipher ancient spells written in a long - forgotten language.
Well, an effect in Harry Potter fanfiction is that it gives fans a chance to continue the story in their own way. They can imagine what happens after the events of the books. A side effect is that sometimes the magic system in fanfictions can be misused or over - exaggerated. Some fanfictions also have the effect of making characters more complex. For instance, they might give Draco Malfoy more redeeming qualities. But a side effect could be that in trying to be different, some fanfictions lose the essence of what made the original Harry Potter series so great, like the sense of wonder and discovery.
One impact is that it has inspired new writers. Many people who started writing fanfiction for Harry Potter have gone on to write their own original works. It has given a platform for creativity. Also, it has increased the cultural influence of the Harry Potter series even more. The fanfiction spreads the ideas and concepts of the original work to a wider audience.
One possible plotline could be that in a post - war world, Narcissa and Harry find themselves drawn to each other through mutual understanding. Maybe Harry sees a different side of Narcissa that was hidden during the war, and they start to build a relationship from there that leads to marriage.
Well, one effect might be the expansion of the magical world. Fanfiction often adds new places or creatures. In this case, it could show how these new elements interact with the existing 'Harry Potter' world. As for side effects, there could be a distortion of character personalities. Sometimes fanfic writers take creative liberties and change a character's nature too much. Also, it might create plot holes in relation to the established 'Harry Potter' lore. For instance, if a new magic is introduced without proper consideration of the existing magical rules.
Family loyalty is also a big theme. Narcissa is deeply tied to her family, and fanfictions often play with the conflict between her loyalty to her family (like Lucius and Draco) and her possible newfound understanding or connection with Harry. It creates a lot of internal and external drama.
One great 'Harry Potter Narcissa fanfiction' is 'The Redemption of Narcissa Malfoy'. It shows a different side of Narcissa, exploring her inner thoughts and her journey after the war. It's a very character - driven story that gives Narcissa more depth than what we see in the original books.
I'm not sure if there is a specific fanfiction with such a plot. Fanfiction covers a wide range of themes and ideas, but this one seems rather unorthodox and might not be very common. There are many fanfiction platforms out there, but it's difficult to say for sure without a thorough search.
