Well, in some fanfictions, it could be due to a powerful spell gone wrong that transfers the ownership to him. Maybe a spell meant to protect Diagon Alley's property rights backfires and suddenly Harry is the owner.
He might have to deal with a lot of administrative work. Running Diagon Alley means taking care of all the shops, making sure the wizards and witches who work there are happy, and dealing with any disputes. For example, if two shop owners have an argument over a piece of land in Diagon Alley, Harry would have to step in and sort it out.
Maybe it's a new character created by the fanfiction author. This new character could have special abilities or a unique backstory that ties into the reason for escorting Harry to Diagon Alley.
Harry is strolling through Diagon Alley, looking for new robes. He bumps into Daphne near Madam Malkin's. Daphne gives him a cold look at first, but Harry smiles sheepishly. Then Daphne's expression softens a bit as she realizes it's Harry Potter. They start chatting about how difficult it is to find robes that fit just right, and Daphne mentions a little - known shop where she gets her best - fitting robes.
One interesting fanfiction could be about a young wizard discovering a hidden magic shop in Diagon Alley in 1993. Maybe it has some rare magical items that are key to solving a mystery in the wizarding world.
Some fanfictions might focus on the darker side of Diagon Alley in 1993. For example, a story could be about how the alley was affected by the presence of dark wizards during that time. There could be battles, secret pacts, and characters having to make difficult choices to protect themselves and the alley. This type of fanfiction would be exciting to read as it adds a new dimension to the familiar setting of Diagon Alley.
Yes, there are quite a few. You can find them on some popular fanfiction websites like FanFiction.net or Archive of Our Own. Some of these fanfictions explore unique storylines where Harry's upbringing in Diagon Alley exposes him to different magical cultures and characters earlier, leading to some really interesting twists on the original story.
Well, one scenario could be that Harry meets a very strict tutor who specializes in Defense Against the Dark Arts. This tutor might push Harry to learn advanced spells and techniques right from the start. Another could be that he gets a tutor for Potions who has a really unique way of teaching, like using rare ingredients found only in Diagon Alley's hidden corners. Maybe the tutor is an old wizard who has a vast knowledge of magical potions and their history.
One possibility is that their meeting is not so friendly at first. Daphne, coming from a certain Slytherin - pure - blood mindset, might be a bit haughty towards Harry. But as they talk, Harry's kindness and honesty could break through her initial prejudice. They could end up having a deep conversation about the differences between the houses at Hogwarts, and how they both want to make the most of their time at school, despite their different backgrounds.
