There are different aspects in a novel and one of the major aspects is the narrative aspect of a novel. What do you call the other aspects? I am thinking non-narrative, but non-narrative aspects of a novel is vague and non-descript. I, honestly, don't know what all of the aspects are, but I think there's only one another aspect aside the narrative aspect of a novel and that it encompasses worldbuilding, so that's why I wouldn't choose "non-narrative" as an adjective.
What would be a better word than "non-narrative"?
