Huragok

Huragok, also known as Engineers and Savants, are the only known non-combative race amongst the Covenant forces. They were artificially created by the Forerunners. They are an incredibly peaceful race, and frowned upon the Human-Covenant war. They are silent beings, and speak in a form of sign language. Huragok are incredibly intelligent and are very good mechanics. The Yanme'e were replaced as engineers by the huragok and placed in the military. This sparked some conflict between the Yanme'e and the Huragok. One Huragok, Lighter Than Some, was a victim of this aggression. As a peace treaty to the humans, he also made the Brute Chopper. It was later used by the Jiralhanae as a weapon. They are generally very antisocial, and will only talk to eachother and to their superiors, the Prophets.
