Father Answin

As the melee ensued, Father Answin let go of his flamer and brought forth his chainsword, holding it in front of himself in a solemn gesture, lowering his head as if in prayer.
"The time of Retribution has come, brothers and sisters! The God- Emperor guides our hands and blades! Let the Reaping commence!"

It let out a vicious metallic scream as he activated it.

The priest joined his followers in the melee, looking to attack the mutineers' leader if he could spot them or, failing that, attacking whomever seemed most opportune. Using the force from the charge, Father Answin brought the gruesome rotating blades down on his opponent with a powerful blow.
