Deacon

Deacon is a Covenant rank. As the name suggests, a Deacon is used for religious reasons rather than combat. A Deacon is sent to help reinforce the spirituality of ships in which not much is present. They command more respect than the rank and file grunts, but are still held in low esteem. A Kig-Yar shipmistress Chur'R-Yar was tempted for the Deacon Dadab to be 'lost' out of an airlock, if not for his ability to communicate with the Huragok Lighter Than Some. Halo, Contact Harvest pg 57.

Known Deacons

 * Dadab

Deacons are not mentioned in any game but are only in Halo: Contact Harvest. The Grunt Dadab is the only known Deacon. However, there are presumed to be many more, due to Dadab mentioning the group that he had studied with to gain the rank.
