One possible fanfiction could be about Harry's struggle with the Blood Quill in a more in - depth way. Maybe it shows how he copes with the physical and mental pain it causes. He could be trying to find a way to break the magic of the quill without getting caught by Umbridge.
A plotline could be where the Blood Quill is used by a different villain. Suppose a new dark wizard or witch gets hold of the Blood Quill and uses it to torment students at Hogwarts. Harry and his friends then have to find a way to stop this new threat.
A great fanfiction I recall is one where the blood quill starts to write prophecies when used. The prophecies are related to the future of Hogwarts and the wizarding world. Harry and his friends have to decipher these prophecies while also dealing with the fact that the blood quill is causing harm to those who use it.
It often changes their view of authority. Characters who have experienced the blood quill first - hand might start to question and rebel against any form of authoritarian rule in the wizarding world. They would see that not all those in power are good, and they would strive to create a more just and equal society within the fanfiction's narrative. This can lead to all kinds of political and social upheaval in the story.
Some fanfictions might explore the origin of the blood quill in more depth. Maybe it was created by an ancient and evil wizarding sect. In these stories, the blood quill isn't just a tool for torture but has a deeper, more sinister backstory. For instance, it could be tied to a dark prophecy or a long - forgotten curse that the main characters have to uncover in order to defeat an emerging threat.
There might be a fanfiction where the blood quill is stolen from Umbridge and used against her. The story could explore how the tables are turned and she experiences the pain it causes. It could also show how the students who were once victims gain power from this act.
On the other hand, some characters might become more determined to fight against injustice because of the Blood Quill. They see the cruel use of the quill as a symbol of the wrong kind of authority in Hogwarts. So, it can be a catalyst for character growth and rebellion in a way, inspiring them to stand up against those who misuse power like Umbridge.
Another plot could involve a character who is forced to use the Blood Quill and they start to have strange visions. These visions lead them on a journey to find a way to break the dark magic associated with the quill. They might meet some unexpected allies along the way, like a house - elf who has knowledge of forgotten magic that can help.
In Harry Potter fanfiction, a blood donor could be a very interesting concept. Maybe a character needs a special blood type to recover from a dark curse. For example, if a student was poisoned by a rare magical plant, and the antidote required the blood of someone with a particular magical lineage. A brave Gryffindor might step up as a blood donor, showing the selfless nature that the house is known for. This could also create a lot of drama and tension in the story, as the act of donating blood in the wizarding world might have unforeseen consequences, like an unexpected magical bond forming between the donor and the recipient.
Fanfiction about 'blood brothers' in the Harry Potter universe can be really interesting. It might explore a deep bond between two characters that's as strong as brotherhood. Maybe it delves into how they support each other through the challenges at Hogwarts, like facing dark wizards or difficult exams. It could also add new layers to the existing relationships in the original story.
