Kraeldonia: The Dual Kingdom

From publisher blurb: Kraeldonia is another strange land on Ert. There are three distinct, cohesive groups in this land, the highland clans, the dwarven holds and the lowland freeholders. The people of the lowlands are generally either farmers or fishermen or maritime raiders. Those of the lowlands pay nominal fealty to King Magnus in Hightor, though they run their affairs with little heed from the highland clans.
