Ordo Mortem is largely made up of hardened Terran criminals that seek repentance for their crimes. Stripped of their names and identity, they become Apostates of Mortem and are sent out to find redemption through meaningful death against those that threaten the innocent. Only those that have served their sentencing can earn the right to have a name again, becoming Black Guard and eventually the lethal Death Guard. Nightress Osi Valdis is an especially skilled warrior that came to the mainland and established a new branch of the Ordo with the express purpose of hunting down the rogue nobleman, Baron Rowan. Of course the land of Kenshi is also filled with dangerous bandits, cruel slavers, killer machines, and vicious wildlife that make for suitable opponents for their members to find their meaningful deaths at the hands of while making the land just a little bit safer to live in for the innocent.

Under Osi's direction and leadership they chose to establish a foothold in the Cannibal Plains to hunt the painted savages while also serving as a staging ground from which their Redemption and Justice squads move further inland. The Cannibal Grand Wizard and Meat Lord have both been identified as key chiefs of the tribes, bringing either of them in to Mortem's Mercy will earn you the favor of the Ordo Mortem and the protection of their squads out in the field.

Ordo Mortem patrols can be found in most of the dangerous areas of the world, even stretching all the way to the Ashlands to combat the skeleton legions.
