The 'Black Cloud Graphic Novel' may tell a story where the black cloud is more than just a weather feature. It could be a metaphor for the dark times or problems that the characters are facing.

There could be a hero or a group of heroes who are trying to figure out the origin and purpose of this black cloud and how to deal with it, whether it's through scientific means or some sort of magical or spiritual solution.
Another possibility is that there is a villain in the story who is somehow related to the black cloud. Maybe they are the cause of it or are using it for their own malicious purposes.

And there's often a connection to the past, like the ghosts being victims of some past tragedy that is somehow related to the location of the black cloud.
