Hermione is the focal point. But other characters from The Order would play significant roles too. There could be some lesser - known Order members who are the instigators of the betrayal. Also, Harry and Ron might also be important as they are Hermione's closest friends. Their reactions to Hermione's betrayal by The Order would be a big part of the story, whether they stand by her or are conflicted by the actions of The Order.
Obviously Hermione is one of the main characters. As for the others, it could include members of The Order such as Dumbledore, Sirius Black if he was still alive in the context of the story, and other Order members who are involved in the act of betrayal.
It could be a new character introduced in the fanfiction. Maybe someone who has infiltrated the Order and wants to create chaos by turning them against Hermione. This person could be a spy from the Death Eaters or another dark - aligned group, with the goal of weakening the Order from within by making them lose one of their most intelligent and powerful members.
I'm not sure specifically as there could be many different interpretations in fanfiction. It might be about a situation where The Order, perhaps in the Harry Potter universe, betrays Hermione in some way, like leaving her in a dangerous situation, or not believing her when she has crucial information.
Hermione is definitely one of the main characters as it's in the title. There may also be other characters from the original series who are part of the order she's being initiated into, like Harry or Ron. And of course, there could be some original characters created specifically for this fanfiction who play important roles in her initiation process.
In fanfiction scenarios where Hermione is betrayed by the Order, it could be related to a prophecy. Maybe there is a prophecy that involves Hermione in a way that the Order misinterprets. They think that by betraying her, they are saving the wizarding world. Or perhaps there is a conflict of ideology. Hermione might have some new ideas or approaches to magic that the more traditional members of the Order oppose. And they see her as a danger to their established ways. Also, personal grudges among the Order members could spill over. If someone in the Order has a long - standing grudge against Hermione for some past incident, they could convince others to betray her.
It could be that a member of the Order, out of jealousy or a wrong perception of Hermione's power, convinces the others that she is a liability. So, they betray her by not believing in her when she discovers something important or by preventing her from using her skills to help. Hermione, being the strong - willed character she is, would then strive to prove them wrong and expose the real issues within the Order.
Ron is a likely candidate. In the original story, they had their ups and downs, and in fanfiction, it's easy to imagine him doing something that Hermione would see as a betrayal, like not supporting her in her academic pursuits. Another could be Draco Malfoy. He could pretend to befriend her for some devious reason and then turn on her.
She would probably be very hurt and angry. Hermione is a strong - willed character, so she might immediately start trying to find out the truth and clear her name.
It depends on the specific plot of the fanfiction. It could be a friend who turns against her due to jealousy, or perhaps a false ally within the so - called 'light' side who has ulterior motives.
It could be that an external force, like a dark wizard in disguise, is the main antagonist. This dark wizard targets Hermione because of her potential to be a great threat to their evil plans. They use magic to cloud the minds of her friends, making them believe Hermione is up to no good. The friends, being under this spell, betray Hermione without realizing they are being manipulated. The dark wizard then watches as Hermione struggles with this betrayal, all part of their grand scheme.
The main characters are Harry and Fleur, no doubt. However, depending on the plot of the fanfiction, characters like Voldemort or his Death Eaters could also be important. If the betrayal is related to the war against Voldemort, they could be the ones who manipulate Fleur into betraying Harry. Additionally, members of the Weasley family might be involved. For instance, if Fleur has a relationship with Bill Weasley, his family's reaction to her betrayal of Harry could be part of the story.
