Another character could be Severus Snape. In the original series, his true loyalties are complex and hidden. In fanfiction about light and darkness, his past, his love for Lily, and his actions that straddle the line between the two sides can be further delved into, making him a key character to explore in this context.
Draco Malfoy is also a common main character in these types of fanfictions. He comes from a family with strong ties to the dark side, but he also has moments of hesitation and potential for good. His struggle between following his family's path into the darkness and choosing a different, more positive path is a rich area for exploration.
Harry Potter himself is often a main character in such fanfiction. Since he is the central figure in the original series, exploring his journey between light and darkness can add new layers to his character. He has his own internal battles with the allure of power and the darkness that he has faced in his life, like the connection with Voldemort.
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.
Obviously, Harry Potter is the central character. But other characters like Hermione and Ron are often involved too. They might have different reactions to Harry's new 'King of Darkness' persona. Dumbledore could also be a major character, as he might try to guide Harry or figure out how to deal with this new development. Voldemort could also play a significant role, perhaps seeing Harry as a more formidable opponent or a potential ally in his own dark schemes.
Draco Malfoy is another character that appears in many 'Unknown Heritage' fanfictions. His family's connection to the dark side could be further explored through an unknown heritage aspect. Perhaps there is a part of his family's past that has been hidden, and when it's revealed, it either redeems him or makes him even more complex as a character.
One main theme is identity. The fanfiction often shows how the character's intersex identity shapes who they are in the wizarding world. For example, how they fit into the Hogwarts houses which are based on certain traits. Another theme is acceptance. It explores whether the other characters in the story, like friends and professors, accept the intersex character for who they are. It can also be about discrimination, as in some fanfics, the intersex character may face unfair treatment from some parts of the wizarding community.
One main theme is the clash and combination of different magic systems. Since Harry Potter has its own set of magic rules and Rayearth has a very different kind of magic, fanfictions often explore how these two interact.
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.
Dumbledore is often a main character in Harry Potter 1945 fanfiction. Since he was around during that time, many stories explore his youth, his friendships, and his early battles against the dark forces.
Often, the main character is an original creation. This could be a self - inserted character who has read the Harry Potter books in their own world and somehow gets transported into the wizarding world. They then use their knowledge of the story to become a 'conqueror' and change things for the better.
