Harry is, of course, the main character. Neville could be an unexpected helper. Maybe he has come across a rare herb during his Herbology studies that has the potential to heal eye problems. And Luna Lovegood might also be part of it, with her unique insights and knowledge of the wizarding world's more esoteric aspects, she could offer some unorthodox but effective solutions for Harry's eye problem.
Well, it could be about Harry having some sort of eye problem, like an injury or a magical curse on his eyes. And then through some means in the fanfic world, perhaps with the help of a powerful wizard or a special spell, he gets his eyes fixed.
Dumbledore could also be a key figure. He has so much knowledge and wisdom that he might know some ancient magic or spell that could cure Harry. He could guide Harry through the process of getting his health fixed and offer moral support as well.
Well, perhaps Harry would finally be able to fully focus on his studies at Hogwarts without being held back by any lingering health issues. He could become even more proficient in magic, and might be able to take on more challenging tasks and adventures.
One character could be Harry, of course. The other main character could be a singer named Ava who is performing in Vegas. She's got a big heart and a wild side. There could also be a Vegas local named Jack who befriends Harry and kind of guides him through the process of getting married in Vegas, giving him local insights.
Obviously, Harry would be the main character. His friends like Hermione and Ron could also be important. Hermione might help Harry with the intellectual aspects of his job, like research or paperwork.
Obviously, Harry would be the central character. He's the one seeking revenge. Hermione would also likely be involved. She might be torn between her loyalty to Harry and her belief in the Order. If she sides with Harry, she could use her intelligence to help him in his revenge plot, like coming up with elaborate plans to outwit the Order. Ron could also play a significant role. He might initially be against Harry's idea of revenge but then slowly come around as he realizes Harry's reasons.
Hermione would surely play an important role. She could help Harry figure out the details of his inheritance, like deciphering old documents or researching the history behind it.
Obviously Harry would be one of the main characters. And Hermione might also be involved, perhaps she helps Harry get the job or gives him advice on how to do it well.
Obviously, Harry himself is a key character. His own strength, both physical and mental, could play a role in his release. For instance, he might have developed some new magical abilities during his time in Azkaban that help him break free.
Well, perhaps Harry's inheritance includes a hidden library filled with ancient and powerful magic spells. This could lead him to become even more powerful and help him defeat the remaining dark forces. He could also share this knowledge with his friends, making them stronger as well.
