Octavian (The Time of Angels)

 was a Bishop from Second Class who had deployed Dr River Song on a covert mission which led with her prescence on the Byzantium (ship) which housed a lonesome Weeping Angel. When he arrived with his clerics at the crash site of the Byzantium, he wasn't happy with River as she had apparently promised an army, but it turned out she had promised the Doctor. This in turn, pleased Father Octavian.

He led his men into the Maze of the Dead below the Byzantium, three of whom were soon killed by the Angel. The Doctor assured him they could not have been saved, but Octavian reminded him that he would be the one to tell their families while he went off in his blue box
