One idea could be a new student arriving at Hogwarts. They could be a muggle - born with a very unique magical ability that even the professors are surprised by. This new character could start making friends with the main characters like Harry, Hermione and Ron, and get involved in some mystery that is starting to unfold in the school.
A former Death Eater who has had a change of heart could be the main character. They are now trying to make amends and start a new life. Their past experiences would make them a complex and interesting character as they struggle to fit into the new, post - Voldemort wizarding society.
Since it's a Harry Potter fanfic with 'a new beginning' in the title, it could center around a major shift in the existing relationships in the series. It could be that Harry, Hermione, and Ron start a new chapter in their lives where they have to deal with long - forgotten secrets that surface. This fanfic might also introduce new magical creatures or spells, and show how these elements change the dynamics of the wizarding world they know.
It's hard to say without reading it. It could be the original characters like Harry, Hermione, and Ron if it's a continuation of their story. Or it might focus on new characters created by the fanfic author.
It can be shown through a change of location. For instance, if a character moves to a different magical realm, like the Beauxbatons Academy in France. The new environment, with its different architecture, teaching methods, and social norms, would signify a new start. They'd have to adapt, make new friends, and face new challenges, which is a classic way of presenting a new beginning.
One possibility could be a new beginning for a minor character. For example, Neville Longbottom could start a new life as a respected herbology professor in a different wizarding school, sharing his knowledge and inspiring a new generation of young wizards. He could have overcome his insecurities and found his true calling, far away from the shadow of Hogwarts and his past self - doubting days.
It could be about Harry Potter having a new kind of adventure or a different life path in the fan - created story. Maybe he has new magical abilities or different relationships.
It could be about Harry starting a new life away from the wizarding world, perhaps in the Muggle world. He might use his magic in secret to help Muggles in need.
