A dark skinned woman with many scars, when on duty she wears a heavy breastplate over dark robes and chainmail. She carries a large heavy hammer, marked with skulls. 
In the Age of Sigmar she was guarding a caravan of pilgrims travelling to the temple of the Order of Final Rest in the Blood Wastes. They were attached by Khorne Bloodbound and rescued by Stormcast Eternals under Lord-Celestant Tarsus Bull-Heart and more reluctantly, Mannfred von Carstein. 
With their aid, they reached the temple and carried out their duty, gifting the tithe to the Restful Brothers. The temple itself was then assailed and she helped defend it against the warriors of Chaos until they were slaughtered by the transformed brothers who had tasted their blood. 
She and the other pilgrims then waited at the temple for them to return from their pursuit to tend to them until they could return to their contemplations.
