Land in which the cities of Sarnath, Ib and others existed in the story The Doom That Came To Sarnath. Although later implied to exist in the Dreamlands, Lovecraft originally envisaged it as existing in the ancient past, possibly in Arabia. As Carcosa and the Nameless City are both linked with Arabia, it is possible that they, too, existed in Mnar. Some of the gods of Mnar are identical to the Great Ones of the Dreamlands (some of which were also known in Hyperborea).
