Forerunner caste system

The Forerunner caste system was a system used to rank Forerunners in society. 
==Organization==
Castes were divided into several tiers, including Rates, Guilds and other subdivisions.
Position 	Rate 	Subdivisions

Third Highest 	Lifeworker 	Unknown
Second Lowest 	Warrior-Servant	Promethean

==Culture==
Adolescent Forerunners, known as Manipulars, were not associated with any particular caste. However, upon maturing, each individual Forerunner would be assigned to a rate, mostly in accordance with the rate of their parents. For example, Bornstellar-Makes-Eternal-Lasting was expected to become a Builder like his father.
Each rate had their own ceremonial headgear, worn only on special occasions. However, on a certain day in the Grand Star Season, every Forerunner wore the same style.Halo: Cryptum - Page ???
