In the fanfiction, the first students could be a mix of young wizards and witches who have shown exceptional magical abilities but didn't fit into the traditional Italian magical schools. There might be a young wizard who has an affinity for ancient Roman magic but was not encouraged in his previous school. And a witch with a talent for transfiguration but was bullied in her old place. Harry Potter's new school in Italy could be their new home, where they can explore their magic freely.
Maybe some young mutants that Harry discovers during his travels in the Muggle world. He could sense their powers and offer them a place at his new school.
His own children could be among the first students. They would bring their own experiences of growing up with Harry Potter as a father, and also their unique magical abilities. And Neville Longbottom's children might also be there. Neville has always been a great friend of Harry's and his kids would inherit Neville's strong sense of justice and love for plants, which could add a different dimension to the student body.
Hermione would be a likely first employee. She's intelligent and organized, perfect for handling complex tasks in the factory. Ron could also be there, helping with the physical aspects of setting up and managing things. Hagrid might be involved too, perhaps in charge of getting some of the more unusual or dangerous ingredients for the factory's products.
Well, perhaps Harry Potter decides to build a school in Italy to spread the knowledge of magic in a new region. He might face challenges like getting approval from the Italian Ministry of Magic, if there is one in the fanfic. And he would need to find suitable teachers who are familiar with both the British and Italian magical traditions.
Hermione would definitely be one of the first people to help. With her vast knowledge of magic and her organizational skills, she could assist in setting up the curriculum and library. Ron could also help, perhaps in handling the more physical aspects like building repairs or helping with the magical creatures that might be part of the school. Neville could contribute his knowledge of Herbology to create a great garden for the school.
Perhaps it's a girl orphan who was found wandering near the Forbidden Forest. She has no memory of her past but shows great potential in potions. Harry feels a connection to her because she seems so lost, just like he once was. So, he decides to take her in as the first orphan in his new orphanage.
Hermione could be a main character. Since she was a Muggle - born witch, her Muggle schoolmates might be very curious about her new life. Harry could also be involved as he had some experience in the Muggle world. Maybe even Ron, as he's always curious about Muggle things. Their presence would bring an interesting dynamic as they try to balance their wizarding selves with the Muggle environment of the reunion.
It could be a mix of students from different houses. In Hogwarts, students from all four houses come together for classes. Harry, having experienced the unity and rivalry among the houses, would be able to handle the diverse group of students well. He might encourage more inter - house cooperation in his classes, breaking down some of the traditional house rivalries.
It could be Hagrid. He loves all kinds of magical creatures and would be very interested in seeing what Harry has in his pet shop. He might even give Harry some advice on taking care of the more dangerous ones.
It could be his loyal owl, Hedwig. She might be staying with him in the attic, providing comfort and also being a messenger for him when he needs to communicate with his friends outside.
