The major human social groups in the Continuation are divided into culturally unified Nations, each of which spans several planets.
(Earlier forms: Aejdar, Aeshtar) A Nation of warriors that strongly prizes honor, courage, and religious faith, traditionally comprised of Nine Clans, though in later times these affiliations are less precise.
A Nation that places strict limits on the uses of high technology. In daily life, they typically live as hunter-gatherers with non-electric and limited mechanical and agricultural tech. They keep high tech for special use in designated tech centers.
The Leddies form a confederated democratic republic, comprised of diverse subcultures. Their dominant culture is concerned multiple identities and perspectives, including gender switching.
A very high-tech and science-oriented Nation, responsible for much of the technological innovation and philosophy of technology in the Continuation. They prize reason and stability.
An expansionistic Nation with a sense of manifest destiny to bring unity to known space. Their Nation was devastated under mysterious circumstances at the end of the Kiri-Sama War (the War's End) and their remnants formed subcultures on scattered planets, many later under Ash'torian domination.
