Who could be the key characters in 'harry meets death at the veil fanfiction' aside from Harry?

Well, Hermione's parents could be key characters. They might be the ones who first notice Harry's odd situation when they meet him. For example, they could see that Harry seems a bit underfed and neglected, which could lead to them trying to help him in some small way. This would also give Hermione more of a connection to Harry before Hogwarts.

Maybe Harry has a deep conversation with Death. He could be seeking answers about the afterlife or the fates of his loved ones who have passed on.

Hermione and Ron would likely still be main characters. Hermione would use her intelligence to help Harry understand his new identity and its implications. Ron, with his loyalty, would stand by Harry through any difficulties that come his way. There could also be Death himself, who might make appearances to guide or test Harry. And perhaps Dumbledore, as he always has a role in Harry's life in the wizarding world, could be involved in helping Harry navigate this new revelation.

Hermione would most likely be one of the main characters. She's always observant and caring towards Harry. So when she notices something is off with Harry, she would do everything in her power to figure out what's wrong and help him. She might use her extensive knowledge of magic to find a solution to his emotional distress.

Hermione would surely be involved. She could be Harry's research partner, helping him find relevant medical information in books and scrolls. Her intelligence and thirst for knowledge would be very useful in exploring new areas of medical magic. Another character could be Madam Pomfrey. She could be Harry's mentor, teaching him the basics of wizarding medicine and guiding him in his new role as a medic.

Hermione would surely be there. She might be a fellow professor, teaching a subject like Transfiguration or Ancient Runes. She could be Harry's confidante and help him with academic matters at Hogwarts. Also, Ron could make an appearance, perhaps as a visiting lecturer from time to time, sharing his knowledge of wizarding chess and other aspects of wizard culture.

His child, of course. Depending on the story, the child could be a young boy or girl. If it's a boy, he might be eager to learn magic from his father and get into all sorts of mischief at Hogwarts when he's old enough. If it's a girl, she could be more interested in the magical creatures and want to follow in Hagrid's footsteps.

Maybe the OC is a wizard from a different magical culture. For example, he could be from a far - flung wizarding community that was not directly involved in the war but has unique magical abilities. Neville could also be an important character, perhaps collaborating with Harry and the OC on projects to revive the magical plants that were damaged during the war.

I think Dobby could be an important character. Since Harry is raising himself, Dobby might take it upon himself to secretly help Harry. He could provide some food and small comforts when Harry is all alone. Another character could be Hedwig. She would be more than just a pet; she could be Harry's only true companion, helping him in small ways like delivering messages or even warning him of danger.

The main characters could include the butterfly's kin. For instance, if the butterfly is part of a colony or a family of magical butterflies, they would all be important. They might have different abilities and personalities. There could also be a wise old owl in the butterfly's world that acts as a guide for Harry, teaching him about the new world he's in. And don't forget about the possible presence of a shadowy figure that lurks in the background, representing the unknown danger that Harry has to face.
