The largest centers are Gok'Lat, upon the Dvina river, the only market town in the entire kingdom, as well as Syk'Kar, found on the Sosola river in Gaa'Kaa. Nearly half the towns number a thousand or more inhabitants, forming immense fortifications against the largely uncontrolled hinterlands.
Bjarmaland was consolidated as a kingdom by gnolls, influenced by advancements in culture west from Samoyadia in the 4th century. Small waves of migrants established themselves over the next four centuries, primarily in Glu'Bak, until such time as war began with the elves of Ulthua. A difficult and long-lasting struggle began for possession of Lake Onega in the mid-8th century, culminating in the decimation of the gnolls at Caerlon in 811. An exodus of gnolls from the west to the east began the year after; Syk'Kar was founded in 813 as the new capital and Vor'Kurta even further north in the shadow of the Urals.
Human incursions began in the 12th century by Novgorodian traders, who found the narrow river lands too well settled to encourage military expeditions. An uneasy treaty was signed by both parties after southern Gaa'Kaa was invaded by the Mongol ogres & uruchai orcs. These did not successfully challenge the gnoll dominance over their northern lands, but forests south of the Pechora source ceased to be part of the Bjarmic domain.
