The Old Dominion are a faction made up of undead soldiers and constructs reanimated from the power of the original god that men worshiped on Ea. The Hundred Kingdoms faction are all refugees of the lands that are now inhabited by the undead Old Dominion after the Hundred Kingdom’s ancestors fled their god going mad to make everyone very undead. While their god going mad wasn’t great for the Hundred Kingdoms, it did create the undead faction of the Old Dominion which is my favorite in the game of Conquest.
