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 are taught in the religion of the Covenant and work to increase faith in others. Deacons are also learned in the "sacred glyphs" that the Forerunners use in their machines. Deacons command more respect than the rank and file grunts, but are still held in low esteem. A Kig-Yar shipmistress, named Chur'R-Yar, was tempted to lose Dadab "out of an airlock", if not for his ability to communicate with the Huragok Lighter Than Some. Dadab was later killed by Tartarus on the orbital known as the Tiara.

Trivia

 * 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.
 * it is added that a Grunt becoming a Deacon is very rare.
