Hyperborea was a legendary continent in the Arctic. Before it was overwhelmed by the advancing ice sheets of the Pleistocene age, Hyperborea was warm and fertile with lush jungles inhabited by the last remnants of the dinosaurs. A race of yeti-like bipeds known as the Voormis once populated Hyperborea, but were wiped out by the pre-human settlers that migrated here from the south. These pre-humans built the first capital of Hyperborea at Commoriom. Later they moved to Uzuldaroum when prophesies foretold of Commoriom's doom.
