The Empire of Iuz is controlled by the half-demon demigod Iuz. It is full of evil, oppression, and armies of horrific beings. Priests of Iuz and other evil spellcasters rule in Iuz's name in these areas. It is said that Iuz's full reach extends past these areas, as he has implanted demonic influences into the minds of many leaders across the Flanaess.
The Empire of Iuz consists of five loosely-defined political regions, though they are not considered actual provinces:
Land of Iuz[]
Also called the Homeland of Iuz, this region lies mainly between the Dulsi and Opicim Rivers, south of the Cold Marshes, and north ofWhyestil Lake.
Bandit Lands[]
Once referred to as the Bandit Kingdoms, this region lies west of the Zumker and Artonsamay rivers, east of the Ritensa River, and is bounded in part by the Fellreev Forest and Bluff Hills. This region is actually made up of a number of warlord fiefs.
Barren Lands[]
These grasslands south of the Icy Sea and the Wastes are also known as the Barrens, the Barren Plains, or the Northern Barrens. North of the Bandit Lands, the Barrens' eastern border is formed by the Forlorn Forest, western Griff Mountains, and the Bluff Hills. Their western border is formed by the Cold Marshes and Opicim River. Once ruled by the nomadic Flan tribes known as the Rovers of the Barrens, these people are but a shadow of their former glory.
Horned Lands[]
This region is bound by Whyestil Lake, the Veng and Ritensa Rivers, and the Fellreev Forest. These lands were for a time ruled by the Horned Society, before Iuz once again took control during the Greyhawk Wars.
Shield Lands[]
Bordered by the Ritensa river, Nyr Dyv, and Rift Barrens, this land was ruled before the Greyhawk Wars by the chivalrous order known as the Knights of Holy Shielding. Though a western portion of the Shield Lands were reclaimed in the Great Northern Crusade of 586-588, the majority of the area is still under Iuz's control.
