The basic concept is this: Players both new and old can take a portal from the main game world to the Epic servers. From there, they will be stripped of all their items and skills, though they will retain all gold in their banks. After that, it's the duty of the players to build and defend kingdoms, which in turn further the goals of their gods on the moon of Valrei. Gods, in turn, have the ability to "reshape the world or spawn creature invasions as a result of how well they achieve their goals."
