Set of more or less contiguous regions of the Prime Roots. One can travel directly from one to the other, by foot. They are the analogous, in depth, of the continents or more precisely subcontinents. The homins have access, from the New Lands, to two super-regions : The Lands of Umbra (four regions) and the Wastelands (three regions). The isolated regions of the Prime Roots are, as on the surface of the bark, called "islands".
