Map of the Land of Oz. "Oz is completely surrounded by deserts, insulating the country from invasion and discovery. The isolation may be splendid, it is not total: children from our world got through, as well as the Wizard of Oz and the more sinister Nome King. To prevent further incursions, Glinda created a barrier of invisibility around Oz."
