An interesting original character could be a half - elf named Elio. He works in a Diagon Alley bakery, baking magical pastries with ingredients that have special properties. He has a troubled past, being half - elf, and is trying to make a name for himself in the wizarding world. Also, a character like a young wizard named Finn who is a bit of a troublemaker. He's always getting into scrapes in Diagon Alley, whether it's accidentally setting off fireworks in the middle of the street or trying to steal a peek at the new brooms in Quality Quidditch Supplies before they're officially released. There could also be an old wizard named Aldric who has a shop full of enchanted maps that show not only the wizarding world but also hidden realms that no one else knows about.
How about a character named Nova, a talented wand - maker's apprentice? She's from a long line of wand - makers but is trying to put her own spin on wand - making. In Diagon Alley, she's constantly experimenting with new woods and cores for wands. Another original character could be a street urchin named Pip. He has no family and survives by doing odd jobs in Diagon Alley. He has a natural talent for finding lost things, which often gets him into both trouble and adventure. And then there's a witch named Aria who runs a magical music shop in Diagon Alley. Her shop is filled with instruments that play by themselves and magical sheet music that can change the mood of the entire alley when played.
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.
One original character could be a wizard named Aiden. He has the power of teleportation but can only do it within a certain radius. This limitation makes his power both useful and challenging. There could also be a witch named Celeste who has the power of charm - speaking, which is like a super - powered version of the Imperius Curse. She can make people do almost anything she wants just by speaking to them in a certain way. And a centaur named Brutus who has the power to read minds at a short distance could be added. He could be an ally or a source of information for Harry and his friends in the fanfiction.
It could be an old, retired Auror. They would have a wealth of practical knowledge about magic and how to use it in dangerous situations. They could teach Harry how to sense dark magic and protect himself better.
He could meet a famous wizard author who is signing books in Diagon Alley. This wizard could give Harry some valuable advice about his future.
A young witch named Luna, not the same as Luna Lovegood, who has the power to control the weather within the Hogwarts grounds. She could be a new friend for Harry and get involved in his adventures. Another could be a wizard named Orion, who is an expert in ancient runes and helps Harry decipher some hidden messages. There could also be a half - elf named Elara, who works in the Hogwarts kitchen and has a special connection with the magical plants there.
One idea could be a story about a young wizard who discovers a hidden, long - forgotten shop in Diagon Alley. Maybe it has magical artifacts that are tied to an ancient prophecy. Another could be a fanfic where a group of students start a secret club in Diagon Alley to practice a new form of magic that's not taught at Hogwarts. Or perhaps a story where a character has to solve a mystery involving a series of strange disappearances in Diagon Alley shops.
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.
One common theme is the exploration of different magical sub - cultures within Diagon Alley. Since it's a hub of magic, Harry could be exposed to various types of magic that are not as prominent in the original series. Another theme could be his relationship with the magical creatures that are often found in Diagon Alley, like owls or the goblins at Gringotts.
