Orcs are a monstrous humanoid race found throughout the lands of Ur. The largest populations are found in the southeastern Belgarth and in the Arawn desert.
The Belgarth population consists mainly of small tribes that will form into hordes when faced with unusually harsh seasons that will then raid the Northeastern Stormlands and/or the Northwestern Huin (and in turn cause the nomadic Huin to raid their neighbors).
In southern Roden an Orcish empire has formed in the Arawn desert. Known as the Dead Empire, it is a caste-based Theocracy ruled by death revering religion. The empire is ruled by a caste of half-orc clergy who are supported by an Orc warrior caste. Most other the other castes are also Orc with humans making up only the slave caste.
