Maybe in a post - war scenario, Lucius has lost his status and Hermione, out of her sense of justice and mercy, tries to help him rehabilitate. This could lead to a series of events where they both learn more about each other's pasts and how they were shaped by the wizarding society. They might even develop an unlikely friendship.
One idea could be that they are forced to work together on a magical research project. Hermione's vast knowledge and Lucius's experience in the wizarding world create an interesting dynamic. They start off hating each other but gradually come to respect one another's abilities.
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.
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.
A possible plot idea is that in an alternate universe, the wizarding world has different alliances. Hermione and Abraxas meet at a magical symposium where they are both presenting on different forms of magic. They initially clash but then realize they have more in common than they thought. Or perhaps there is a mystery that only their combined skills can solve. Maybe a dark magic artifact that is related to both Gryffindor and Slytherin, and they must put aside their differences to stop its power from being misused.
One common theme is redemption. Lucius is often portrayed as a character in need of redemption, and Hermione is the one who can help him see the error of his ways. This can involve him gradually changing his views on Muggle - borns and the Dark Arts.
One possible plot idea could be a story where Lucius is forced to work with Hermione on a magical project due to some unforeseen circumstances in the wizarding world. As they interact, he starts to notice her intelligence and courage in a new light, and his initial disdain turns into an unexpected attraction. This could lead to a lot of internal conflict for Lucius as he struggles with his pure - blood beliefs and his growing feelings.
One common theme is redemption. Since Lucius has been a Death Eater, many fanfics explore his journey towards redemption with Hermione often being a catalyst for this change. For example, her values and her belief in second chances can inspire Lucius to turn his life around.
In this type of fanfiction, it could start with Hermione being an orphan for some reason. Lucius, seeing her magical abilities and intelligence, decides to take her in. At first, Hermione would be very much out of place in the Malfoy Manor. However, as time passes, she might start to change the Malfoy family's views little by little. Lucius would have to deal with the reactions of other pure - blood families, and Hermione would face challenges from both the Malfoy family's expectations and the outside world's perception of her being in the Malfoy household.
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 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.
