The concept for the comic was created by Bob Johnson, who worked together with John Alvey to create the story of a hard-boiled cop who suffers a "psychic head wound" and finds himself caught up in a spiritual battle set in a landscape of mythological beings. In fighting this war he comes face to face with the darkness in his own life, which has left him with no feeling for his fellow humans.
In the Legendary Comic-Con@Home panel on July 23, Johnson explained that he began writing as an outlet while he was suffering from stage 4 non-Hodgkin lymphoma and that the idea for the story came to him in a dream. Isaac, Johnson, and Alvey have been friends since childhood, but this graphic novel is their first comics collaboration.
