Pious Inquisitor

The Pious Inquisitor was a Covenant vessel of unspecified classification reputed to be "one of the fastest ships" in the Covenant Fleet. The Pious Inquisitor saw action at the First Battle of Earth. The multiplayer level Midship is located in an unspecified section of this vessel. Surprisingly, its luxury leads towards the speculation that the vessel possibly was the Prophet of Regret's Flagship. Though it is unknown where the location of the map is, it is a commonly thought to be either in the Bridge or the Engine room. It is more likely the former though because of the layout of the room. The main hovering part of the room is in the center.
