Warrior-Servant

Warrior-Servants were a caste in Forerunner society. During the Human-Forerunner War, they piloted War Sphinxes into battle. A particular group of Warrior-Servants known as the Prometheans created "Warrior Keeps" known as Cryptums, the nature of which was unknown to most Forerunners.

The use of the word "servant" in their name implies that they are of lower social status than standard Warriors.
