One interesting plot could be a case of false accusation. Maybe someone framed Hermione for a serious dark magic crime she didn't commit. The story could then focus on her trying to prove her innocence from within Azkaban, perhaps with the help of some unexpected allies like house - elves who she had previously befriended. Another plot might involve a time - travel twist. Hermione is sent to Azkaban in the present, but through some magical accident, she travels back in time while in prison and has to find a way to change the events that led to her imprisonment. A third possibility is a political conspiracy within the wizarding world. High - ranking officials send Hermione to Azkaban to silence her because she was about to expose some dark secrets about the Ministry of Magic.
Harry Potter is an obvious choice. Given their strong friendship and the many adventures they've had together, Harry would surely do everything in his power to rescue Hermione. He has faced many challenges before and wouldn't stand by while his friend is in Azkaban. Another likely character is Ron Weasley. He and Hermione have a complex relationship, but he would definitely not let her rot in Azkaban. Ron has his own skills and resources within the wizarding world that he could use to plan a rescue. Dumbledore, if he were still alive in the fanfiction, would also be a likely rescuer. He was always one to see the good in people and Hermione's intelligence and value to the wizarding world would make him want to save her. He has the power and influence to challenge the decision to send her to Azkaban.
Maybe a jealous wizard or witch within the Ministry of Magic. They might be envious of Hermione's popularity and influence among the younger wizards. So they fabricate evidence against her to get her locked up in Azkaban.
If Harry is sent to Azkaban in fanfiction, it would be a huge shock to the wizarding world. In Azkaban, the dark and gloomy environment would take a toll on him. But Harry has a strong will, so he might try to resist the effects of the Dementors. His Gryffindor courage would be put to the ultimate test. And he may discover some secrets about Azkaban while he's there, which could lead to a whole new plotline in the fanfiction.
One possible scenario in such a fanfiction could be that Harry is wrongly accused of a serious crime and sent to Azkaban. Snape, who has always had a complex relationship with Harry, might initially believe in his guilt due to their past animosity. However, as the story unfolds, Snape could start to suspect that there is more to the situation. He might begin his own investigation, secretly at first, to find out the truth behind Harry's imprisonment. This could lead to a series of events where Snape has to face his own prejudices and also deal with the political situation in the wizarding world that allowed Harry to be sent to Azkaban so easily.
To survive in Azkaban, Harry would need to keep his mind active. He could recall all his happy memories to counter the Dementors. His knowledge of magic could also be useful. For example, he could try to create some protective spells around his cell. And he might get some unexpected help from the guards or other mysterious forces within the prison.
In such a fanfiction, the plot might involve false evidence being planted against Harry. Maybe someone uses dark magic to create the illusion that Harry has committed a serious crime, like using an Unforgivable Curse. The Ministry of Magic, being quick to judge, sends him to Azkaban without a proper investigation. Harry would then have to find a way to prove his innocence from within the prison, perhaps with the help of his friends who believe in him and are secretly working on the outside to clear his name.
If Harry Potter were sent to Azkaban in fanfiction, it could be a very dark turn of events. He would likely be wrongly accused, as he often is in the face of Ministry corruption. His time in prison might involve him using his magic in secret to resist the Dementors, and it could also lead to an uprising within Azkaban by other inmates who believe in his innocence. It could also prompt his friends to stage a dangerous rescue mission.
In fanfiction, if Harry Potter were sent to Azkaban, it would be a huge deviation from the original story. He would likely face extreme hardships. The Dementors there would constantly drain his happiness. His friends, like Hermione and Ron, would probably try everything to prove his innocence and break him out. It could also lead to a situation where Voldemort might gain more power without Harry being able to oppose him freely in the wizarding world.
Well, perhaps in the fanfiction, Hermione is wrongly accused of a serious crime like dark magic use. Maybe some powerful and corrupt wizarding figure wants to silence her for her Muggle - born rights activism. So they frame her and she gets sent to Azkaban.
