Governors of Contrition
From Halopedia, the Halo wiki
The Governors of Contrition was a radical fringe sect of Covenant who believe that all creations of the Forerunner are sacrosinct. They also believed that the Flood were a perfect life-form and that it was the duyt of the Covenant to protect and embrace the Flood (Despite the fact that there is no evidence that the Forerunners created the Flood.).
Despite these radical beliefs, the Governors of Contrition are apparently accepted into society so long as their beliefs to not endagner others. Members of the group have even ascended to the rank of Ship Master.
Members of this group included Tano 'Inanraree
