Descended from numerous different peoples who once served as Thassilon’s military caste, the barbaric Shoanti might well someday become Golarion’s newest ethnicity. Unlike the more prolific Varisian people, these proud folk have not spread far beyond the lands of their ancestors. They dwell primarily in the uplands of the Storval Plateau or the hills of northern Varisia, where they hold their own against the many terrors that vie for territory in these wild lands. As Varisia becomes increasingly civilized, it’s more common to see Shoanti turn their backs on tradition to dwell in the greater comfort afforded by civilization — and in some cases Shoanti are becoming part of society on a governmental level.
Physically, the Shoanti are the most akin to the Kellids or Ulfen, but generations of isolation allowed them to develop their own complex tribal society, divided into seven different “quahs,” or clans. They speak a language called Shoanti similar to both Varisian and Hallit, but with a fair amount of Thassilonian as well. Anyone fluent in these three languages can communicate basic ideas in Shoanti, but only those who learn the tongue can ever hope to earn true respect from these proud people.
