The term "Gorean" refers to the fictional planet described in the works of John Norman. Synonyms for this term include "Gor", "Gorius", and "Gorwellian". The world of Gor is characterized by a patriarchal society where dominance and submissiveness are heavily emphasized. Other terms sometimes used to describe this theme in fantasy literature are "slave worlds" or "planetary romance". Norman's works also often feature themes of BDSM, which have led to criticism and controversy in some circles. Despite this, the depiction of Gor and its associated mythology remains popular among a subset of readers interested in the themes of domination and submission.
