"Cabal is a coral of a character, an agglomeration of sources literary and cinematic combined with some of my own ideas for characters. I cannot honestly say I sat down and constructed him. He was lurking around in my head, becoming more Cabal for a long time. When I finally came to write the first chapter of Johannes Cabal the Necromancer, I had no idea if he was going to live on the page. Then he started giving Satan lip, which I hadn’t been expecting. My first thought for that scene was that he would be confident but cautious. When he started chiding Satan on lifestyle choices, I knew he was going to be okay."
