Khar-Gaos
A monotheistic religion that rose to prominence during the orcish conquests, which holds the Infernal Kharag-Gar as its supreme deity. Khar-Gaos holds all the Creators, Siblings and Versai as well as the other Infernals to be pseudo-immortal demi-gods who seek to pacify and subjugate Kharag-Gar in order to use his incredible powers for their own ends. Khar-Gaos is not formal or structured and there are no churches. Worship of Kharag-Gar is illegal and blasphemous bascially everywhere.
Outside of the developed regions, there are many tribes that practice Khar-Gaos, and goblins and tuckers often have shamans and other mystics in their clans who have continued to practice Khar-Gaos since the orcish conquests. Some scholars believe that Khar-Gaos may in fact have originated with goblins, and was only adopted and spread worldwide during the orcish conquests.
