Between Aquilonia and the Pictish Wilderness lie the Bossonian marches, peopled by descendants of an aboriginal race, conquered by a tribe of Hyborians, early in the first ages of the Hyborian drift. This mixed people never attained the civilization of the purer Hyborians, and was pushed by them to the very fringe of the civilized world. The Bossonians are of medium height and complexion, their eyes brown or grey, and they are mesocephalic. They live mainly by agriculture, in large walled villages, and are part of the Aquilonian kingdom. Their marches extend from the Border Kingdoms in the north to Zingara in the southwest, forming a bulwark for Aquilonia against both the Cimmerians and the Picts. They are stubborn defensive fighters, and centuries of warfare against northern and western barbarians have caused them to evolve a type of defense almost impregnable against direct attack.
The Bossonians are particularly well versed with a bow. They are known as some of the best rangers in the Hyborian world, only challanged by the Shemites.
