This book started with an empty toolbox for blending illustration and prose. As I go along certain techniques pop up, but I don't want to over use them. It also has to make sense within the context of the story. Here for example, two of the characters are walking into the rough section of the city. Dilapidated factories, boarded up shops, anything that represents the collapse of the magical industry. Instead of bloating the prose with description, i decided to "wall in" the text with the buildings surrounding the characters. This, again hopefully, not only conveys some of the description visually but also mirrors the characters experience. And it was also a chance to slip in a bunch of magician references.
