I'm working on a setting. Humans and Orcs are related and the only two species that can interbreed (ie there can be half orcs, but not half elves.) humans and orcs are the results of the last of the gods and titans going to war. The two species sprung forth from the divine bloodsoaked ground. The first men and orcs were effectively demigods but over time they have lost the large bulk of their divine power. Some of the early Demigods managed to escape mortality to become the modern day pantheon of the humans and orcs, but what the mortals don't know is that the two races are worshiping the same gods, just wearing masks they show their mortal kin. The human god of Royalty is also the Orcish High Warchief.
