It could be a long - lost relative of Voldemort. Maybe a distant cousin or something who has the same thirst for power and has decided to target Harry and his friends to gain more influence in the wizarding world.

The main characters would start with Harry Potter. Then, there could be some members of the pure - blood families. For instance, Draco Malfoy could be a key character. His family's obsession with blood purity and his own complex relationship with Harry could be further explored in the context of Harry's control over blood magic. Also, characters like Neville Longbottom could be involved, perhaps his connection to his family's history through blood could be related to Harry's new power.
