As I am now thoroughly committed to the next book, The Wizard in his Keep, I have also been working on the little matter of what you put on the cover of the book.
I started with a picture of two important characters, the video-game characters Hoodwink and Babbles (the horse-headed Kelpie).

Next came the color step.

Which leads to the need for a background.

And then we edit it and composite it.

And hopefully it makes you at least a little bit interested in the story.
