Obviously, Harry Potter himself could be a main character. He might be drawn into the story of the serpent king due to his inquisitive nature and his constant fight against dark forces. His friends like Hermione and Ron could also be involved, providing their unique skills and knowledge.
A great plotline might involve the serpent king being a misunderstood figure. Instead of being a pure villain, he has his own motives and goals, like protecting a certain part of the magical world that has been long forgotten or oppressed. In the fanfiction, Harry could find himself in a moral dilemma of whether to fight or side with the serpent king.
Well, it depends. Just because the story is based on a real story doesn't necessarily mean the serpent is a literal, physical snake. It could be a symbolic serpent representing something in the real - life events, like a person or an organization that acts in a sneaky or dangerous way, much like how a snake is often seen in literature. But if it is a more straightforward account, then it could be a real snake.
I recommend "Speak to the Sword". This fantasy novel had a plot of the resurrected King Wu and his wife, and also mentioned the Ba-Serpent. This novel used the power of the King Wu as its main theme and described the story of all living beings fighting for the honor of immortality. I hope you like this fairy's recommendation. Muah ~😗
Well, 'The Serpent' takes inspiration from actual incidents. It weaves a narrative around real-life circumstances, but with some creative liberties for dramatic effect.
Well, it could be inspired by real elements but not necessarily a 100% accurate account of something that happened exactly as told. Many such stories blend fact and fiction.
