The Ministry of Magic officials who strictly enforce the marriage law could be antagonists. They might be so bent on following the rules that they don't consider the individual feelings of Charlie and Hermione. For example, an overzealous bureaucrat who keeps checking on them to make sure they are fulfilling their marital duties according to the law.
Some traditional pure - blood families might oppose their union. They may think that Charlie, being more of an outdoorsy and dragon - loving type, and Hermione, a Muggle - born with a thirst for knowledge, are not a suitable match. These families could try to create problems for them, like spreading rumors or trying to get the marriage annulled.
There could be other characters who are also forced into marriages by the law and are jealous of Charlie and Hermione's growing relationship. So they try to sabotage it. Maybe a wizard who was paired with someone he didn't like and sees Charlie and Hermione getting along well, so he decides to cause trouble for them.
One possible fanfiction could be where the Marriage Law forces Hermione to consider Charlie as a potential partner. Maybe they start off as reluctant allies, but as they get to know each other through the arranged situation, they discover shared interests in magical creatures. Hermione's intelligence and Charlie's hands - on experience with dragons create a unique dynamic.
Sometimes, other characters from the Harry Potter series can also play important roles in this type of fanfiction. For instance, George Weasley, Fred's twin, might be involved in helping Fred deal with the situation or providing comical relief. And Harry Potter himself could be there to support his friends through this strange turn of events.
There could also be secondary characters like their friends. For instance, Harry and Ron might be involved. Harry could offer his support and advice to Hermione, while Ron might be a bit more skeptical about the whole Hermione - Oliver relationship. Their reactions and interactions can add depth to the story. Also, Oliver's Quidditch teammates could play a role, perhaps causing some tension between Hermione and Oliver when it comes to his time on the team.
Hermione Granger, the Muggle - born wizard with a thirst for knowledge and justice, is a main character. Marcus, whose character might be developed in various ways in different fanfictions, is the other main character bound to Hermione by the marriage law. Their friends from Hogwarts such as Harry and Ron may also be involved in the story. They could either be skeptical about this strange union or try to help Hermione and Marcus navigate through the difficulties brought by the marriage law.
One idea could be that they initially resist the marriage law due to their different worlds in Hogwarts. Charlie is all about dragons and Hermione is focused on academics. But as they start to spend time together, they discover they share a love for magical creatures in a different way. Hermione starts to see the beauty in Charlie's wild dragon - taming ways, and Charlie is amazed by Hermione's vast knowledge which could be useful in dragon conservation.
The main characters are obviously Snape and Hermione. Snape is a complex and often misunderstood character in the Harry Potter universe. Hermione is the brilliant, book - smart witch. In this fanfiction concept, they are brought together by the marriage law.
Hermione and Harry are the central figures. However, other characters like Ron also get affected. Ron's relationship with Hermione and Harry is put to the test because of this law. He might feel jealous or left behind. Also, characters like Dumbledore or Snape (if the fanfic includes them in this context) could play roles in either supporting or opposing the law which in turn affects Hermione and Harry.
Perhaps in the fanfiction, Hermione is initially very angry about being paired with Charlie under the Marriage Law. But Charlie takes her to his dragon reserve. There, Hermione sees a different side of Charlie and his passion for magical creatures. This experience makes her more open - minded towards him. Meanwhile, Charlie starts to admire Hermione's intelligence and her determination to fight for what she believes in. Their relationship slowly evolves from forced to something they both cherish.
Draco Malfoy would be an interesting choice. Their long - standing enmity could be turned on its head by the Marriage Law. It would create a lot of tension and conflict at first, but as they get to know each other, they might find common ground, like their shared love for their families in different ways.
Voldemort could be an antagonist. Even if Tom is a character in the marriage contract, Voldemort's ideology and his followers might oppose the union as it could potentially change the power dynamics in the wizarding world that they are trying to control.
