A plotline could involve Draco's family trying to hide his non - pure - blood origin for generations. When Draco finds out, he could start to question his family's values and actions. He might then try to find out who his non - pure - blood ancestors were and what their story was. Maybe he forms an unlikely alliance with some non - pure - blood characters in Hogwarts as he tries to come to terms with his new identity. There could also be a plot where the discovery of his non - pure - blood status changes his relationship with Harry Potter. Instead of being rivals, they could become allies as Draco realizes the unfairness of the blood - based discrimination in the wizarding world.
In this fanfiction, a plotline could be centered around the mystery of Draco's non - pure - blood heritage. It could start with some strange events or magical anomalies that lead Draco to suspect something is off about his family's pure - blood claim. As he delves deeper, he uncovers a web of lies and secrets that date back generations. This discovery could send shockwaves through the Slytherin house, where the idea of pure - blood supremacy is strong. Draco might then have to decide whether to keep the secret or expose it, knowing that either choice would have far - reaching consequences. His relationship with his parents could be severely strained as he grapples with this new reality. And on a broader scale, his non - pure - blood status could be a catalyst for change in the wizarding world's views on blood purity, especially if he decides to fight against the discrimination that he has now become a part of, in a way he never expected.
I'm not sure it's a 'popular' concept in a general sense. It might be popular among certain fans who like to explore different takes on Draco's character. Maybe it challenges the traditional view of his pure - blood status in the original story, which could attract those who want to see more complex and alternative interpretations of the wizarding world's blood hierarchy.
Another plotline could be that she was cursed as a child and lost her memories. Years later, she starts to regain her memories and realizes she is a Malfoy. Draco then has to help her navigate the wizarding world that she has forgotten while also dealing with his own feelings about having a long lost sister. It could involve adventures in finding a way to break the curse completely.
One possible plotline could be Draco trying to hide his squib status from his family. He might go to great lengths to fake being a wizard, like using magic - like tricks or relying on others to do magic for him in front of his family. Another plotline could be Draco befriending other squibs and forming a sort of underground community where they support each other and try to prove their worth in the wizarding world. Or, he could be discovered as a squib by his enemies, like Harry Potter and his friends, and instead of the usual animosity, they feel pity and try to help him come to terms with his new reality.
Perhaps the twin sister has a special power or ability that Draco initially wants to use for his own gain. He tries to befriend her under false pretenses. But as he gets to know her better, he realizes she's not just a means to an end. For example, if she has the power to communicate with magical creatures, Draco, who is interested in the more elite aspects of the wizarding world, might see this as an opportunity to impress his family. However, as he spends time with her, he starts to care about her for who she is, and they develop a relationship that goes against the expectations of their respective friend groups and families.
One possible plotline could be that Bella and Draco meet in a magical crossover event. They initially dislike each other due to their different upbringings, but as they are forced to work together to solve a mystery that threatens both their worlds, they start to understand and respect each other. There could be no romantic or inappropriate elements, just a story of two characters from different universes finding common ground.
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.
One possible plot could be that Draco Malfoy is magically sent to Westeros. He gets caught up in the power struggle between the Starks and the Lannisters. Maybe he tries to use his knowledge of magic to gain an advantage, but soon realizes that the politics of Westeros are far more complex than he expected.
Maybe Lucius has a secret admiration for Hermione's tenacity. In a plotline, he could be under a curse that makes him see the good in those he once despised. This leads to him being charming towards Hermione. She, in turn, is initially suspicious but gradually starts to question her own views of him as he continues to be kind and helpful in unexpected ways.
Another plotline could be a time - travel scenario. Draco gets sent back in time to Camelot. He becomes an apprentice or a follower of Arthur Pendragon. He then has to learn the ways of Arthur's court, deal with the politics and magic there, and in the process, he grows as a person, bringing back some of Arthur's wisdom to his own time when he eventually returns.
One possible plotline could be that Harry, through some magical accident or inheritance, comes to own Draco's family manor. Draco is then forced to interact with Harry on Harry's terms to regain his family's pride. Another could be that Harry wins a bet against Draco and the terms of the bet are such that Harry now has ownership over Draco's time, making Draco do tasks for Harry.
