The Southron Wastes were once an area that was kept fertile by the watershed caused by the One Forest, now they are a desert caused by a man-made ecological disaster.
The felling of the One Forest caused the watershed to change, and the once fertile kingdom with its capital at Doriendor Corishev became uninhabitable. It is now said to have no life or safe passage.
Its former inhabitants migrated north into the Land during the Era of the Old Lords. In the Era of the Desolation, Stonedownors lived in the Southron Wastes, sustained by their Rhadhamaerl Lore, before returning to the Land at the beginning of the Era of the New Lords.
