Narcissa can be developed by showing her growth from a victim to a survivor. At first, she may be meek and submissive due to the abuse. But as the story progresses, she could become more assertive. For example, she starts to speak up against Lucius's actions in private, which is a small but significant step.
Narcissa might be very angry with Harry's abusers. If it's the Dursleys, she could use magic to give them a taste of their own medicine, but in a more subtle way so as not to draw too much attention. For example, she might make their houseplants grow out of control or cause their food to spoil every time they're mean to Harry.
They can be portrayed as a very traditional couple. Lucius as the dominant figure, making important family decisions, while Narcissa is more focused on taking care of Draco. But they both have a deep respect for each other's roles in the family.
At first, it would likely be very strained. Harry has a history of conflict with the Malfoys, and Narcissa is a Malfoy. But over time, they might start to communicate more. They could find that they both have a love for the wizarding world's history and start sharing stories. This could lead to a more amicable relationship.
I'm not sure if there is such a specific fanfic available. Fanfics cover a wide range of scenarios, but this one might be quite rare or not commonly known. You could try searching on major fanfic websites like Archive of Our Own or Fanfiction.net, but it's not guaranteed that you'll find it.
A popular Snape and Narcissa fanfiction is 'Midnight Whispers'. It focuses on their quiet conversations and the unspoken understanding between them. The story is set in Hogwarts and shows how they navigate the political and social landscape of the wizarding community together. There's also 'Faded Memories' which plays with the idea of lost memories and how they might resurface to change their relationship.
Narcissa Black is a character full of contradictions. Coming from a family with a strong stance on pure - blood supremacy, she marries into another powerful pure - blood family, the Malfoys. Throughout the 'Harry Potter' series, we see her loyalty being tested. While she is initially associated with the Dark side through her family and husband, her love for her son makes her take actions that could be considered against the Dark Lord's wishes. Her character is a great example of how family and love can influence a person's actions even in a world filled with magic and danger.
In the 'Harry Potter' story, Narcissa Black Malfoy was part of the complex web of the wizarding world. Her family's beliefs in pure - blood supremacy were a significant part of her background. However, as the story progressed, we saw her maternal instincts override some of those more rigid family values. Her relationship with other characters like Bellatrix Lestrange (her sister) also added depth to her character and the overall story.
One good fem Harry Potter Narcissa fanfic could be 'The Hidden Bond'. It explores a different dynamic between a female Harry Potter and Narcissa. In this fic, their relationship starts off as a mystery but gradually unfolds into a complex bond that affects the entire wizarding world around them.
In some fem Harry Potter fanfics, Narcissa can become more of a protector. For instance, if the story involves a female Harry Potter who is in danger, Narcissa might step up in ways she didn't in the original series. She could be more assertive in using her influence within the Death Eater circles to safeguard Harry.
