Another idea is that their daughters have unique magical abilities due to their mixed heritage. They could discover a new form of magic that combines the magic associated with Gryffindor and Slytherin. This new magic could put them in a position where they are either feared or revered, and they have to navigate through the political and social implications within the wizarding world.
Perhaps a storyline where Draco and Hermione's daughters are at Hogwarts and are part of a new generation trying to bridge the gap between the houses. Their daughters could start a club or an initiative that promotes unity among the different houses, much like their parents overcame their own house differences. They might face opposition from some traditionalists who still believe in the old rivalries, but they persevere.
One possible storyline could be that their children inherit the best of both worlds. For example, they might have Draco's Slytherin cunning and Hermione's Gryffindor bravery. They could be the bridge between the former Slytherin - Gryffindor rivalry, using their combined skills to solve new magical mysteries at Hogwarts. Maybe they'd form new friendships across houses that were previously unthinkable due to their parents' history.
One possible storyline is that Hermione joins the military to prove herself in a different way than in the academic world. In the military, she could face challenges like dealing with prejudice from non - magical soldiers. She might use her knowledge of different cultures and languages, which she gained from her studies, to negotiate with other groups in the military context.
They could be portrayed as very intelligent like Hermione. They might be top of their classes, always eager to learn new spells and potions. And also have a bit of Draco's elegance and style in their appearance and behavior. For example, they would dress neatly and carry themselves with confidence.
Well, he could end up being a rival to some of the noble houses in Westeros. Maybe he'd use his Slytherin cunning to try and gain power. He might start off as an outcast, just like he was at Hogwarts, but gradually find a way to insert himself into the political games of the Seven Kingdoms.
In this scenario, it could also lead to a major shift in the relationships within the fanfiction. Hermione might feel betrayed if Draco doesn't stand up to his father. And Draco could be forced to make a difficult choice between his family's expectations and his feelings for Hermione. Lucius's interference could also bring in other elements of the wizarding world, like the Ministry or other pure - blood families getting involved depending on how the situation unfolds.
One possible plotline could be that they discover they have more in common than they thought. Maybe they start working together on a project in the wizarding world, like researching a long - forgotten magic. As they spend time together, they realize their feelings for each other have changed from hatred to love. To avoid the chaos that would ensue from their families and friends' reactions, they decide to marry secretly. Another idea is that they are forced into a situation where they have to pretend to be married for some magical reason, like protecting a powerful spell or object. During this time, they start to really fall for each other and end up making it a real, secret marriage.
Well, perhaps Hermione discovers some dark secret of Draco's that she can use as evidence to frame him for a crime, leading to his incarceration in Azkaban. Maybe it has something to do with his family's past actions that she twists to make him look guilty.
One possibility could be through some sort of time - traveling or alternate universe scenario in the fanfiction. Maybe a spell gone wrong sent Hermione back in time and through a series of complex events, she ended up in a situation where she was related to Draco in that way. It's a very creative and out - of - the - box concept that fanfiction often explores.
Draco's father, Lucius, might be very disdainful at first. He has a strong sense of pure - blood superiority and Hermione is a Muggle - born. His mother, Narcissa, might be more reserved in her dislike. She could be more focused on how Hermione's presence affects Draco.
Often, in such fanfictions, there are plots where Hermione tries to keep the pregnancy a secret from the wizarding community at large. She might fear the reaction from both the Gryffindor and Slytherin sides. There could also be a storyline where Draco, despite leaving, has second thoughts later in life and tries to come back into Hermione's and the child's life, creating a lot of emotional turmoil.
