Dumbledore, even though he has passed away, could still be a major part of the fanfiction. His wisdom and past experiences with death, like his sister's death, could be explored further. His spirit or memories could guide the living characters in their exploration of the aspect of death, providing cryptic clues and moral lessons along the way.
Obviously, Harry Potter himself would be a main character since the title revolves around him. Hermione and Ron are also very likely to be involved.

Dumbledore could also be a part of it, perhaps as someone who failed to notice or prevent Harry's abuse initially.

Neville Longbottom could be a key character. He might take on a bigger role in Hogwarts in Harry's absence and also be in touch with Harry, providing support from the school.
