 In common with the other Pusadian tales, "The Stone of the Witch Queen" takes place in a prehistoric era during which a magic-based Atlantian civilization supposedly throve in what was then a single continent consisting of Eurasia joined with Africa, and in the islands to the west.It is similar in conception to Robert E. Howard's Hyborian Age, by which it was inspired, but more astutely constructed, utilizing actual Ice Age geography in preference to a wholly invented one.In de Camp's scheme, the legend of this culture that came down to classic Greece as "Atlantis" was a garbled memory that conflated the mighty Tartessian Empire with the island continent of Pusad and the actual Atlantis, a barbaric mountainous region that is today the Atlas mountain range.
