There could be a group of rogue Death Eaters who escaped justice and have banded together again. They believe that Voldemort's ideas were right but that he was too weak. So they target Harry, thinking that if they can defeat him, they can finally achieve their goal of a pure - blood - dominated wizarding world. They might be more cunning and less flashy than Voldemort, making them a more difficult enemy to detect.
One possible plot could be that Harry discovers he has a long - lost relative who was a powerful wizard but had been exiled for some reason. This relative has left behind a set of magical tasks for Harry to complete that will lead him to a new kind of magic that he's never known before. It could involve traveling to far - off magical lands and making new allies.
Maybe Harry discovers a new magic that was long forgotten. For example, he might find a spell book in the Forbidden Forest that leads him on this new path of magic exploration.
There could be a new professor at Hogwarts. Maybe a young and brilliant wizard who has just returned from a long journey in a far - away magical land. This professor could bring in new ideas and spells, and become an important figure in Harry's new path.
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.
The third path could involve a unique plot twist where Harry discovers a previously unknown magical ability or artifact that changes the course of events.
One possible plot idea could be that the main character in the fanfic decides to leave their old, mundane life behind. For example, if it's a fanfic based on a fantasy world, they might leave their small village to become an adventurer in a big city. They could face challenges like making new friends, learning new skills, and dealing with the politics of the adventuring guilds.
The main character could also be a new character introduced into the fanfic's universe. For instance, in a Lord of the Rings - style fanfic, a young elf who has grown up in a secluded part of the forest. One day, they decide to leave their home and start a new path, which leads them to get involved in the larger events of the war against Sauron, perhaps by forming an alliance with humans and dwarves.
