A body of water, designated Playa, was located south of the Kharamun desert during the Hyborian Age, and appears only on the 1977 Starmont Map of the Hyborean World that supplements A Gazeteer of The Hyborian World of Conan.
It does not appear anywhere in the text contained therein, and it is currently unknown in which source prior to 1977 "Playa" originated.
