The Harbinger of Piety was a Covenant CCS-class battlecruiser under the command of the Minister of Inquisition.


This vessel participated in the Battle of Earth as a part of the Covenant Loyalist Fleet and was subsequently destroyed by a MAC blast from Nassau Station.[1]

Operational History[]

Battle of Cleveland[]

Main article: Battle of Cleveland

The ship had at least one San'Shyuum; the Minister of Inquisition. The Prophet was curious about a Key of Osanalan, which was in fact, fake; it had been made up by James and Ruwan Ackerson when they were young.

Ruwan Ackerson had met the Covenant and told the Covenant that he was actually the key. Confused, the Covenant took the humans to the Harbinger. In reality, Ruwan had been implanted with an organic tracker for the UNSC to find and destroy high ranking Covenant officials.


  • For unexplained reasons, the Harbinger of Piety is first depicted with four forward ventral fins, as seen on CCS-class battlecruisers in Halo 3. However, the picture of its destruction depicts it as only having two fins like those in Halo: Combat Evolved.
