The Dominion is the world that the Dominus and his subjects inhabit. Its structure and makeup is malleable, subject to the whims of the Mookreator.

The Dominion is made up of several planes: earth, fire, air, water, creation, destruction, law, chaos, heaven, hell, metal, vegan, and Extra Crispy.

Locations on the physical realm of the Dominion include Callan, Maltak, Semash, FaRIA, and the Wild Edge Territories.
