Australasia

From publisher blurb:

The Atlas of Earth-Prime goes down under, to the continent of Australia and the islands and oceans in the Pacific. Written by a native Australian, this Atlas entry offers an overview of Australia, then introduces us to Federal City and the hidden super-advanced civilization of Warrangina and its hero/leader Wandjina. Also included are the national hero Blue Ensign, the vigilante Nighthaunt, and the Southern Stars—along with descriptions of a number of villains. It also introduces Amphitritus, a sunken city that’s a sister to Atlantis with its own king, Ormor the Aquarian.
