Though I think they more mean Ellis' work is affected/inspired by/about the demise of western civilization. I could be wrong about that assumption, though, and I never got that feeling off The Man's work, precisely.
I would not be riding with Ellis if that weren't true.
Dear Mr. Warren Ellis,
If you are ever in need of grunts and/or meat shields because everything is your fault and the world Governments want you dead, please feel free to call upon my services.
