Another possible genre could be a coming - of - age story. If the main character is young and through their experiences with the dragon fire, they grow and change, learn about themselves and the world around them. This would make 'Dragon Fire' a coming - of - age novel, with the dragon - related elements adding a unique and exciting twist to the traditional coming - of - age narrative.
A third theme could be identity. The dragon's unique features, like the dragon eye, might set it apart from other dragons or creatures. The fanfic could delve into how the dragon views itself, whether it is proud of its power or feels burdened by it, and how it defines its own identity in the context of the story.
It could be a thriller. Sudden death often makes for a great thriller element, with the tension and mystery it creates.
Maybe it's a fantasy genre. The 'Star Child' concept can be very much in the realm of fantasy, with magic or special abilities related to stars being part of the story.
If it exists, it might be a horror genre novel considering the 'ghost' in the name. Ghosts are often associated with horror stories.
It might be a survival genre. If the cold is a major factor, then it could be about characters struggling to survive in a harsh, cold environment. They would have to deal with things like lack of food, shelter, and the threat of freezing to death.
It could be mystery. Many collections might have a set of mystery novels in a list of seven.
Maybe it's a fantasy novel. Stars can be used symbolically in fantasy, representing some sort of magical or otherworldly power that is cruel to the characters in the story. For example, it could be that a certain constellation has a curse on it that affects the main characters.
It could be that there was some sort of magic involved. Maybe an enemy of Thranduil cast a spell that made the dragon more aggressive towards him. The dragon fire might have some special properties due to this magic, and Thranduil's burns could be not just physical but also have some sort of curse or negative effect on his being. He then has to find a way to break the curse while dealing with his injuries.
There could be detective stories in '7 short stories', where a detective tries to solve a crime. Then there's the genre of coming - of - age stories, which focus on the growth and development of a young character. Additionally, there might be some historical fiction stories that take the reader back in time to experience different historical events through fictional characters' eyes.
It could be a thriller. If the story is set within seven days, there could be a race against time, which is a common element in thrillers.
