From the introduction: The realm is divided into three parts; the charted lands of Central Middlemist with their relatively dense populations, civilisations, roads and trade routes; the uncharted but well known lands of Outer Middlemist, those to the far east, south, north and west where the terrain is at its wildest and only the brave, the foolhardy or the strong venture; and The Lands of Myth, the far lands beyond the known borders of the discovered world.
