There was an Unnamed Minor Prophet aboard the Truth and Reconciliation.
Background
He was attached to the Fleet of Particular Justice during the Battle of Installation 04[1]. He was also member of a small group of the High Council of Masters aboard the ship. No name for him was ever given. This prophet was captured during Lieutenant Melissa McKay's raid on the ship. Rather than the anti-gravity chairs used by many of his kind, he wore an anti-gravity belt.
Death
He died when McKay finally understood that the infected PFC Wallace A. Jenkins was trying to communicate that the Flood needed to be eradicated by destroying it in a ship-to-ship combat suite.
