A plot idea could involve a character who is not the main protagonist in the original story getting hold of the Subtle Knife. This character could be an antagonist or a side - character with their own motives for using the knife. For example, they might try to use it to gain power over the different worlds that the knife can cut through. Or perhaps a story where the Subtle Knife is broken and the characters have to find a way to repair it, which leads them on a whole new adventure full of challenges and new characters.
Serafina Pekkala could be an interesting character to focus on in a 'a subtle knife fanfic'. As a witch, she has her own set of powers and a unique perspective on the events. You could write about how she views the Subtle Knife and its implications for the different worlds. Also, Iorek Byrnison, the armored bear. His strength and loyalty could be a great addition to a fanfic. He could be involved in protecting the knife or helping the characters who possess it in their quests.

Another interesting concept would be to set the story in a post - apocalyptic world where the Subtle Knife is the only hope for restoring order. The characters would have to face new challenges and make tough decisions about who should wield the knife and for what purposes.
One of the main characters is Will Parry. He is a young boy who comes into possession of the Subtle Knife and plays a crucial role in the story. Another important character is Lyra Belacqua, who is also involved in the adventures across different worlds in the graphic novel.
