Promethean

The Prometheans were the highest and most respected group of Warrior-Servants in the Forerunner ecumene. The Didact, the Confirmer, the Grammarian and the Strategos were Prometheans.

Physically, Prometheans were the highest form a Warrior-Servant could mutate to, standing around four meters tall and between 800 and 1,000 kilograms in weight. They were heavily muscled, their hands capable of easily crushing a human skull.

History
Following the Human-Forerunner wars 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.

The Prometheans were responsible for creating "Warrior Keeps" known as Cryptums, where an exiled warrior could live in suspended animation for thousands of years.

Trivia

 * The name "Promethean" was probably inspired by the Titan Prometheus in Greek mythology, who gave the gift of fire to mankind. However, there is no in-universe relation between the names, as the Forerunners predated the Greeks by well over 100,000 years.
