Pious Inquisitor

Summary
Don't let her luxury fool you – the Pious Inquisitor is one of the fastest ships in the Covenant fleet. It is also one of the ships that attacked Earth in October of 2552 along with the rest of the Prophet of Regret's fleet during The First Battle of Earth.

The Halo 2 Multiplayer level Midship takes place in the Engine Room of the Pious Inquisitor. Because it appears to be orbiting Earth, it is generally assumed to be a CCS-class battle cruiser.
