Promethean

The Prometheans were a high class of Warrior-Servants who were responsible for creating "Warrior Keeps" known as Cryptums. The Didact and Confirmer were Prometheans.

History
The Prometheans were the highest and most respected group of Warrior-Servants in the Forerunner Ecumene. Following the Human-Forerunner War and the discovery of the Flood, the Prometheans stood in opposition to the radical faction of Builders who proposed the construction of the Halo Array. They lost the political battle, and were subsequently removed from the Council.
