One creative interpretation could be that the Unbreakable Vow is used in a fanfic to bind two characters in a secret alliance against a new dark force. For example, two students from different houses might make the vow to protect a powerful magical artifact from being stolen by a group of dark wizards who are trying to use it to gain control over Hogwarts.
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.
One common theme is loyalty. Both Snape and Narcissa are very loyal in different ways in the original story, and fanfictions often explore how their loyalties interact. For example, their loyalty to their families and to the wizarding world's power structures.
In the original series, the Unbreakable Vow is a very serious and rarely used magical bond. In fanfic, it can be more common. For instance, in fanfic authors might use it more often to drive the plot forward. They might have characters enter into the vow more casually (compared to the original where it was a big deal).
The allure of Snape and Narcissa fanfiction lies in their complex characters. Snape, with his tortured past and hidden loyalties, and Narcissa, a strong - willed pure - blood witch. Their relationship in the original series is full of unspoken words and hidden meanings. Fanfiction allows writers to explore what could have been between them, like a secret romance or a deeper friendship. It gives a chance to fill in the gaps and create new storylines that the original books didn't fully explore.
Well, in such fanfictions, the story might show Hermione struggling with her new identity. On one hand, she has the strict and somewhat cold upbringing from Snape and Narcissa. This could make her more reserved and calculating compared to the Hermione we know. But at the same time, she still has that thirst for knowledge and justice. Her relationships with Harry and Ron could be strained as they try to understand this new Hermione who has such a different background.
One common theme is loyalty. Both Snape and Narcissa are complex characters with their own loyalties in the wizarding world, and fanfics often explore how these loyalties interact when it comes to their relationship.
One interesting story could be where Narcissa and Snape team up to protect Draco during the dangerous times at Hogwarts. They use their combined knowledge of the Dark Arts and the inner workings of the Death Eaters to keep Draco safe from harm.
In many fanfictions, Severus Snape and Narcissa Malfoy's relationship is complex. Some fanfictions might explore their childhood connections if they had any. They both come from Slytherin, which could be a basis for a deeper bond in these fictional stories.
In some fanfictions, they could be allies in a way that goes beyond what we see in the original books. Maybe they are working together to undermine the more extreme elements of Voldemort's regime. Their combined knowledge and influence could be a powerful force in these fictional scenarios.
