There might be new stories about the relationships between the characters in 'Harry Potter 6'. For example, the budding romance between Harry and Ginny could have some new side - stories, like how they dealt with the challenges of being in a relationship while fighting Voldemort.
I'm not sure specifically which 'Harry Potter 4 new stories' you are referring to. There could be many fan - made or newly released short stories. Maybe they are about new adventures of Harry, Hermione and Ron at Hogwarts, or perhaps they involve new magical creatures and spells.
I'm not sure specifically as there could be various new stories. Maybe they could be about new adventures of Harry's children, or perhaps they explore some untold tales from the original Hogwarts years. It's all speculation without more information.
Yes, if they are published by the official publishers or with the approval of J.K. Rowling, they are likely to be official. This means they are part of the legitimate expansion of the Harry Potter universe.
It's not a new genre. Genres usually have a set of recognized features that help categorize works. This phrase is just an expression to show that the work is about Harry Potter but not in the form of a fan - written fictional piece. It might be a unique approach to creating something related to the Potter world, but not a genre in itself. There are already established genres like fantasy, mystery, etc. in the Potter - related works, and this doesn't fit into that framework as a new genre.
There are also some new short stories and additional information released by J.K. Rowling on the official Wizarding World platform. These might not be full - length novels like the original Harry Potter books, but they do add more depth to the world, such as details about the Hogwarts houses and the backstories of some minor characters.
Well, it's likely that Harry Potter himself could still be a main character, perhaps as a mentor to the new generation. His children might also be main characters, as they carry on the Potter legacy at Hogwarts.
Yes, they are official. JK Rowling is the creator of the Harry Potter universe, and any new stories she releases are considered official additions to the franchise.
