One plot idea could be that in a world where dark forces are targeting Hermione for her intelligence and her role in the fight against Voldemort. Snape, due to his complex relationship with the Order of the Phoenix, and Lucius, perhaps having a change of heart after seeing the true brutality of Voldemort's regime, team up to protect her. They could hide her in an old, magically protected manor that has been in Lucius's family for generations. Snape uses his skills in potions to create protective elixirs for her, while Lucius uses his knowledge of dark magic to set up wards that only they can pass through.
Well, perhaps in the fanfiction, they are all entered into a magical tournament. Harry, being the young and brave one, Snape with his vast knowledge of magic, and Lucius with his family's resources. At first, they are rivals in the tournament but then realize that there is an outside force trying to manipulate the outcome for evil purposes. So they join forces. Or it could be that a powerful dark magic spell has been cast over Hogwarts, and only the combined magic of Harry, Snape and Lucius can break it. They start off distrustful but as they work together, they form an unlikely alliance.
One plot idea could be that Lucius is forced to work with Hermione on a secret magical project for the Ministry. At first, they are at odds due to their different backgrounds and beliefs. But as they face various challenges together, they gradually come to understand each other. For example, they might have to deal with a powerful dark magic artifact that is causing chaos. Another idea is that in an alternate universe, Hermione is a spy in the Malfoy household and she has to pretend to befriend Lucius while secretly gathering information. This could lead to some tense and interesting interactions as Lucius is a shrewd character and Hermione has to be very careful not to be discovered.
One idea could be a plot where Hermione, through some magical accident, is transported to a time when Lucius was young and they meet under different circumstances. Maybe she has to work with him to solve a mystery that could save the wizarding world in that era. This would force them to put aside their initial differences and form an unlikely bond.
Perhaps in a post - war scenario, Hermione is working on reforming the wizarding laws. Lucius, who has lost much of his power and status, is begrudgingly involved in the process. Through a series of debates and interactions, they develop an unexpected connection that challenges their long - held beliefs about each other.
Perhaps in an alternate universe where the pure - blood and Muggle - born tensions are resolved differently. Lucius, being a prominent pure - blood, and Hermione, a brilliant Muggle - born, are forced to marry for political reasons. At first, they dislike each other but as they get to know one another better, they fall in love and decide to start a family. The story could focus on how they navigate their different worlds while raising their baby.
Another plot could involve the daughter discovering a long - hidden secret about her parents' relationship. Maybe there was a prophecy that led to their union, and she has to figure out how to deal with the implications of this discovery. She could be hunted by dark forces who want to use her for their own gain because of her unique heritage.
One plot idea could be that they are forced into an unexpected union due to some magical circumstances. Maybe a dark magic spell backfires and binds them in a way that leads to Hermione becoming pregnant. Another could be a story set in an alternate universe where they are on the same side and fall in love over time, and the pregnancy is a result of their new - found relationship. It could explore how they deal with the reactions of their respective families and friends.
Perhaps the soul bond is discovered during a time of great turmoil in the wizarding world. Hermione and Lucius find themselves in a situation where they must work together to protect something important, like an ancient magical artifact that could tip the balance of power. The bond makes their partnership more intense and complex, as they have to deal with their own personal feelings and the expectations of their respective sides. Along the way, they might develop a grudging respect for each other that could potentially turn into something more, like a friendship or even a romantic relationship, which would shock their friends and foes alike.
One plot idea could be that Snape takes Hermione under his wing after he discovers her extraordinary magical potential at a young age. He secretly trains her in advanced potions and dark arts defense, much to the surprise of the other Hogwarts faculty. Another could be that Hermione's parents die unexpectedly, and Snape, having a soft spot for her intelligence, steps in as a guardian. He helps her navigate the complex wizarding world politics while she tries to uphold her muggle - born values.
One plot idea could be that during detention, Snape discovers Hermione's hidden talent for potion-making that even he hadn't expected. He starts to see her in a new light, not just as an over - achieving Gryffindor. Another idea is that they get trapped in the detention room due to a spell gone wrong, and they have to work together to get out, which leads to a grudging respect between them. And perhaps Hermione finds an old diary in the detention room that has some secrets about Snape's past, which she uses to understand him better.
