I want to know the answer to the following question:
What is a person called who does the initial pencil work for the artwork?
All the background I'm provided with is that "Particularly in American superhero comic books, the art may be divided between a penciller, who lays out the artwork in pencil; an inker, who finishes the artwork in ink; a colourist; and a letterer, who adds the captions and speech balloons.". Is that enough to answer the question?
