In some fanfictions, when Harry Potter gets his letter at 9, it might be a moment of great excitement. It could be the start of his journey into the wizarding world just like in the original story, but with some unique twists added by the fanfiction author. Maybe the owl that delivers the letter has some special markings or behaves in an unexpected way.
His life could change drastically. He might start to see the magical world in a different light earlier than in the original. For example, he could meet some early allies or enemies right after getting the letter.
One interesting plot twist could be that the letter is delivered by a completely unexpected character, like a house - elf instead of an owl. This would change the whole dynamic of how Harry receives this important news.
There might be a new student at Hogwarts who is also from Harry's neighborhood. They could become fast friends with Harry and be a big part of his adventures at school. This character could bring a new perspective to the story as they are also new to the wizarding world.
Hermione could be the one. With her vast knowledge of the wizarding laws and her sharp intellect, she might dig up some old regulations that prove Harry's right to his money. She would then fight tooth and nail in the wizarding courts or against the goblins at Gringotts to get his money back.
Hermione would most likely be involved. She's Harry's best friend and would be eager to help him understand and manage his inheritance. She could use her vast knowledge of magic and research skills to uncover the secrets behind it.
Dear [Character Name], This letter of thanks is long overdue. You've been an amazing part of my Hogwarts journey. Whether it was in Potions class, where you helped me avoid blowing up my cauldron, or on the Quidditch pitch, cheering me on from the stands. Your kindness and selflessness have not gone unnoticed. I've learned so much from you, from how to handle a difficult Boggart to how to find the beauty in the simplest of magic spells. You are truly a gem in the wizarding world, and I am so lucky to have you in my life. Thank you with all my heart. [Your Name]
He could work at Flourish and Blotts. He's very knowledgeable about magic, so he could help customers find the right books. It would be a great job for him as he loves to read and study magic. He could also recommend books to young witches and wizards starting their magical education.
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.
Another aspect could be related to his family heritage. Harry could inherit a special magical artifact that was passed down through the Potter family. This artifact might hold the key to some long - forgotten magic or a prophecy. As he explores his inheritance, he uncovers secrets about his family's past and its connection to the overall history of the wizarding world, which in turn helps him in his fight against Voldemort.
