I'm not sure specifically as there are many different fanfics with that title. It could involve new adventures of Harry Potter in a world filled with the struggle between lightning (maybe representing some form of magic or power) and darkness (perhaps dark magic or evil forces).
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.
In Harry Potter fanfic, 'lightning on the waves' could potentially refer to a magical phenomenon. It might be a spell that creates lightning - like effects over water bodies. For example, a powerful wizard could use it during a battle near a lake or the sea to create a distraction or attack their enemies. It could also be a metaphorical description of a situation, like a character's sudden realization or a dangerous event that occurs on water and is as sudden and striking as lightning.
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.
In a fanfic, the lightning scar could be a portal. Harry discovers that when he concentrates hard enough and uses a special incantation, he can use the scar to travel to different times in the wizarding history related to Voldemort. He uses this ability to learn more about his enemy, but also risks changing the past and the future of the wizarding world.
I'm not sure specifically as there could be many different takes in a fanfic with that title. It might be about a character in the Harry Potter universe who is seen as the 'prince of darkness', perhaps a new villain or a dark interpretation of an existing character.
I'm not sure specifically as there could be many different interpretations in a fanfic. It might be about a period in the Harry Potter universe where dark forces gain more power than usual, perhaps with Voldemort or other dark wizards having a stronger hold on the wizarding world. Maybe it focuses on how the characters like Harry, Hermione and Ron deal with this new and more dangerous situation.
It could be about many things. Maybe it's about the rise of dark forces in the Harry Potter universe. It might focus on new dark wizards or the resurgence of Voldemort's ideology in a fan - created story.
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.
Well, it could be about a lot of things. Maybe it's about how the forces of darkness are rising in the Harry Potter universe in this fan - created story. It could involve new dark wizards or old foes returning with greater power and how Harry and his friends deal with it.
