It may sound fantastic to link the term "realism" with Conan; but as a matter of fact - his supernatural adventures aside - he is the most realistic character I ever evolved. He is simply a combination of a number of men I have known, and I think that's why he seemed to step full-grown into my consciousness when I wrote the first yarn of the series. Some mechanism in my sub-consciousness took the dominant characteristics of various prize-fighters, gunmen, bootleggers, oil field bullies, gamblers, and honest workmen I had come in contact with, and combining them all, produced the amalgamation I call Conan the Cimmerian.
