The realm system was an idea that Martin Bormann came up with. There where three realms and each realm determined your lifestyle.
The people of the fascist homelands (fascist nations), and fascist reserves (colonies). They live mansions and live life at its fullest. They have at least three houses each and have many places to go and are each assigned a servant.
This realm is anyone who is white and Third Realmers that are in the army or servants. Their life is around the quality of poor USA.
Criminals, Jews and the rest of the world not mentioned. They spend all their lives in factories or on factory farms. They live in the slums.
