The Lost City of Pnakotus (also called the Library City, The Lost City of the Archives and Pnakotis) is located in Australia's Great Sandy Desert. This primordial city is where the Great Race housed their enormous library.
The library of Pnakotus held the Pnakotic Manuscripts, a legendary tome containing a detailed chronicle of the Great Race's history, among other things. Copies of this manuscript would later be passed down through the ages, eventually falling into the hands of sinister cults which would guard them into modern times.
