Doulos

Doulos is the name used for the type of Artificial intelligence (or Associated intelligence) in service to the Wartorn, a covenant remnant. During the time of the Covenant, research into AI was restricted by the penalty of death but only the simplest of intelligence was allowed to exist, barring on non-sentient.

While research into AIs was illegal, High Kaidon Garr 'Alakavai during his time as a Fleet Master would establish a secret facility to conduct such research with a select few, including his friend Khito 'Nucam.

Upon the founding of the Wartorn, semi-sentient artificial intelligence called Doulos have entered service in a variety of different roles within their society from combat drones to starship turrets. They all originate from the UNSC dumb AI Macoun who was captured by 'Nucam early in the Covenant War and experimented upon by Huragok.
