Duospherical Theory

Duospherical Theory is a geographical theory that the world of Helevos is a sphere, with two hemispheres which are the physical reverse of each other. It has been the dominant theory for more than a millennium, with world maps showing Anásthiasplugin-autotooltip__small plugin-autotooltip_bigAnásthias

Anásthias [a-NAS-thee-ass / ænæsθiːæs], or [an-ass-THEE-as] is an equatorial island continent, heart of the Civilised World. The north straddles the equator and is hot and humid, while most of the equatorial centre is an upland plateau with fertile river valleys, and stretches of arid plains and desert in the shadow of the mountains. The south is temperate but more wild, separated from the civilisations of the north by the almost impassable Harthera as a lone island continent on one hemisphere surrounded by sea. The Obverse hemisphere is its literal opposite, being a single sea surrounded by land.

The theory was developed in Saloya around the third century BME, derived from Miyarrain texts that described Anásthias as a continent on a hemisphere of water, surrounded by “Edge Lands” to which they gave various names. The theory likely developed from imaginative cartographers drawing the hemisphere of the known “Civilised World”, and having no knowledge of the rest of the world, filling a blank space with their imagination.
