FOLLOWING ON THE INFORMATION REVEALED in “Who Is This Prosatio Silban, And What Does he Want?” here is a chart listing the Exilic Lands’ inhabitants. It’s meant as a quick reference rather than a last word.
Attentive readers will recognize some of what’s named herein but may or may not have light shed thereby, so: the Xao, Xai and Xax are, like the Aydnzmri and Mazei, descended from the “Antecedents” whose millennia-ago war broke the Exilic Lands (and first gave them that name); but unlike their more refined counterparts, reverted to barbarism.
