I'm not sure since I haven't read it, but it could be a new character who is introduced to explore the concept of darkness. It might also feature some of the well - known characters from the original Harry Potter series, like Draco Malfoy. Given the title, he could be a likely candidate as he has some associations with the darker side in the original books.
It could potentially center around a character who was on the fringes in the original series but now takes center stage in this fanfic. For instance, a character like Luna Lovegood might be the main character, but in a much different light. Maybe she discovers a new aspect of magic that has a dark undertone and she has to grapple with it. Or it could be about an original character created by the fanfic author, who has a unique connection to the darker elements of the wizarding world.
Well, without having read it specifically, it could potentially be about a character in the Harry Potter universe who decides to explore or give in to the darker aspects of magic or their own nature. Maybe it's a story where a character, perhaps a Slytherin, delves deeper into the forbidden arts that are often associated with darkness in the wizarding world.
Since it's a Harry Potter fanfic, it's likely that Harry Potter himself would be one of the main characters. He'd probably be at the forefront of any resistance against the 'reign of darkness'. Hermione Granger would also be a key character as she is known for her intelligence and would be valuable in coming up with plans. Ron Weasley too, as Harry's loyal friend, would be involved.
Since it's a fanfic, it could still have Harry Potter as one of the main characters. Hermione and Ron might also be there. But it could also introduce new characters that are related to the lightning and darkness elements, like a wizard who has special powers related to lightning and an antagonist who embodies the darkness.
It depends on the writer's vision. Maybe it focuses on the children of the original characters. They could be the ones facing the 'rise of darkness'. For example, if Harry has a son or daughter, they might be the main characters. Or it could also be a side character from the original series, like Neville Longbottom, who has now become a key figure in combating this new wave of darkness in the fan - made story.
Most likely Harry Potter himself would be one of the main characters, as he is the central figure in the original series. Hermione and Ron would probably also play important roles as they are Harry's closest friends.
Definitely Harry Potter. He's the central figure in most Harry Potter - related stories. Alongside him, Dumbledore could be a main character, guiding Harry even from the shadows in this 'Descent into Darkness' story. And then there might be a character who is a double agent, perhaps a Slytherin student who pretends to be on the dark side but is actually helping Harry and his friends. This character could add a lot of intrigue to the plot.
The main character is the 'Heir of Darkness', who has a complex personality and backstory. Harry Potter would be a main character as he is often at the center of any major events in the Harry Potter universe. Additionally, there could be antagonists in the fanfiction related to the dark side that the heir might be associated with. For example, a group of dark wizards who want to use the heir for their own evil purposes. And the fanfiction might also introduce some minor characters from the original series in new roles, like Luna Lovegood providing some unique insights about the heir's situation.
In addition to Harry, Hermione and Ron are likely to be important characters. They are Harry's closest friends and are always involved in his adventures. As for the 'Angel of Darkness', it could be a new character created by the fanfiction author. This character might interact with well - known characters from the series like Dumbledore or Voldemort as well, depending on the plot.
Harry Potter is often still a central character. Since it's related to the Harry Potter universe, his journey in the context of the darkness is frequently explored. He might be dealing with inner demons or facing darker versions of his enemies.
Perhaps it could be a corrupted version of one of the existing characters. For example, a character who has been influenced by dark magic and has turned into this 'prince of darkness'. It could be a Slytherin student who has delved too deep into the forbidden knowledge of the house and has become a dark force. Another possibility is that it's a long - lost relative of a major villain like Voldemort, carrying on his legacy in a new and terrifying way.
