Thuria and Beyond
Details as per Monster Manual 3 (1E conversion needed), this goatlike, humanoid-shaped species is native to the eastern foothills of the Hyborian Mountains, where they construct villages made up of simple stone dwellings. Their society is relatively advanced, producing adept metalworkers and weapon makers. In common with the goats to which they are related, ibixians are herbivorous.
Although they tend not to travel widely, adventurous ibixians can be found seeking work as mercenary fighters, bodyguards and the like, taking advantage of their deserved reputation for great strength and fearlessness. Ibixian fighters, then, can occasionally be found in Zamara and in eastern Brythunia. These more well-travelled ibixians can master human languages but speak with a peculiar accent. Those who remain closer to home tend to speak their native language only.
