The fierce Orcs of Arkelon tend to live all across the continents, spread out in different locations and amongst different tribes. However, most Orcs have a preference for establishing settlements in tropical, subtropical or even desert areas. Some tribes do live in more temperate lands, as well.
While some tribes stayed nomadic, true to their roots, some decided to establish some infrastructures on their lands, settling down for good with their tribe. This change, however, took decades to effectively take place, and is still fairly recent.
