Dumbledore might also make an appearance in some form. Maybe as a guiding spirit or through some magical means. His wisdom could play a role in helping Harry through this process.
Obviously, Harry Potter himself could be involved. He might be a mentor figure in the future, passing on his knowledge and experiences to the new generation. His children, if the fanfiction extends to that, would also be key characters. Hermione and Ron could also play important roles, perhaps as educators or as important figures in the wizarding government. Neville Longbottom could be involved too, maybe as a herbology expert who is helping to develop new magical plants for the future wizarding world.
The younger students at Hogwarts are quite likely to read Harry Potter fanfiction. They are at an age where they are really into the wizarding world and would be curious about different interpretations. Students like Colin Creevey, who is a big fan of Harry, might be eager to read fan - created stories about his hero. Also, the members of Dumbledore's Army, such as Luna Lovegood and Neville Longbottom, seem like the types who would be open to exploring fanfiction.
Hermione Granger would surely be one of the first to support him. She's always been by his side, helping him with research and providing intelligent advice. Ron Weasley would also be there, being Harry's loyal friend through thick and thin. Neville Longbottom could be another supporter. He's grown into a brave and capable wizard, and he would stand with Harry in his new role. Dumbledore, if he were still alive in the fanfiction, would likely offer his wisdom and guidance to Harry as he takes on this new and important role.
Well, Hagrid would be a great addition. He could bring in some friendly magical creatures for the preschoolers to see, like baby owls or small unicorns. The kids would be thrilled to meet them.
Hermione is a very likely candidate. With her intelligence, she could easily start a business. For example, she might open a library - like establishment but with rare and restricted magical books that she has managed to collect through her research. She could charge a membership fee for witches and wizards to access these valuable resources.
In addition to the main ones, there could be some original characters created for this fanfiction. For example, a wizard who is secretly working for the Queen's enemies. There might also be some magical animals that are either helping Harry or causing trouble. And of course, the Queen's advisers and guards would be part of the story as they interact with Harry and the magical world.
The main characters would surely include Harry Potter. He's the center of the story as he is the one with the Veela aspect. Ginny Weasley could also be a major character. If Harry is a Veela, it would change their relationship dynamics. Additionally, Dumbledore might play a significant role as he would be guiding Harry through this new discovery and helping him understand and control his Veela powers.
In this kind of fanfiction, Neville Longbottom could also emerge as a key character. He has shown great courage and growth throughout the Harry Potter series. When Hera enters the picture, Neville could be the one who has an unexpected connection with her. Maybe his family's long - forgotten magical heritage has some link to the Greek mythology that Hera represents. And then there are the Death Eaters. If the story is set during the darker times in the wizarding world, the Death Eaters might see Hera as a new threat or a potential ally, making them important characters in the fanfiction as well.
Obviously, Harry Potter and Godric Gryffindor. There might also be some other Hogwarts founders making cameo appearances.
There could be other pure - blood wizarding families' members in the harem. For example, a member from the Greengrass family. And then there might be some half - blood or even muggle - born characters who add diversity to the harem, each with their own motives and backstories that interact with Narcissa's plans and the overall story.
