It could be that a new character is created specifically for this fanfic as the main character. This character might be a young wizard or witch who discovers the secrets of reanimation and has to deal with the consequences. They could be an outcast in the wizarding world because of their dangerous knowledge.
Perhaps a concept in this fanfic is the reanimation of dark wizards. But not in a way that they are simply evil again. Instead, they are reanimated with a new purpose or a changed personality. This could lead to complex relationships and power dynamics within the story, as the reanimated dark wizards have to navigate a world that has moved on without them.
The key elements often include the sense of cosmic horror that Lovecraft is known for. There are eldritch monsters, strange and otherworldly locations. The protagonists often find themselves in situations that defy normal human understanding, facing ancient and malevolent forces that are far beyond our comprehension.
It brings Lovecraft's horror concepts into a more modern and inclusive setting. For example, it shows how the horror affects different races and genders, not just the typical white male protagonists of Lovecraft's original works.
The 'lovecraft first story' is often important as it sets the tone for his later works. It might introduce the unique and often macabre elements that are characteristic of Lovecraft's writing, like the use of the unknown and the cosmic horror elements.
Lovecraft's detailed descriptions also play a big role. For example, in 'At the Mountains of Madness', he describes the grotesque and strange creatures in great detail. The way they look, move, and interact with the environment is both fascinating and horrifying. Also, his use of dark and isolated settings, such as the Antarctic in that story or the strange town in 'The Shadow over Innsmouth', adds to the sense of horror. There's a feeling of being cut off from the normal world and being at the mercy of these unknown terrors.
The graphic novel may simplify some of the complex language in the original stories for a more general audience. However, it also has the potential to add new layers of interpretation through the art. The artists' vision of Lovecraft's world can give readers a different perspective on the stories, and sometimes highlight elements that might not be as obvious in the written text.
