You are a God! You are master and ruler of a loyal nation. You have unimaginable powers at your disposal. You have claimed this world as yours. But there are others who stand in your way. You must defeat and destroy these pretenders. Only then can you ascend to godhood and become the new Pantokrator.
In Dominions you take control of a powerful being that rules a nation and aspires to godhood. The type of Pretender Gods can vary from magically powerful arch mages to huge titans or large monuments. The pretender gods have different strengths dependent on what kind of god you choose and what nation you play.
When you start the game you decide what kind of god you are and how your Dominion affects your lands and followers. It is an expression of your divine might and the faith of your followers. If your dominion dies, so do you. Your dominion also inspires your sacred warriors and gives them powers derived from your dominion.
