Gorean society is divided into "Castes". Each profession comprises its own caste, and each caste is ranked according to its particular place in the Gorean society. Castes are hereditary; meaning each person is born into the caste of his or her father. Although the caste system is rather rigid in its requirements, it is possible for a person to"raise" or "lower" his or her caste according to their ability and aptitude. There are three types of people on Gor that do not have a caste: Outlaws Priest-Kings, and slaves. Each caste has a series of beliefs and rules that one must follow when practicing one's profession. These are called the caste's "codes". Each caste's codes are different. Many of the major castes of Gor have there own unique "Caste Color".
