the world of rules

a world ruled by a creature so beyond humanity that all humans had turned themselves into the entity's worshipers. the world soon had to deals with creatures that the entity creates but the world had found ways of how to survive in this condition with specific rules. The rules keep the world safe and soon the world discovered a stone which could grant you any wish which the entity would do that created special abilities that soon led the world into a new and better era ... so that's what they thought.
