Bardic college obsessed with the study of death, to the point of engineering it
In their beginnings, about a hundred years ago, the Lamenters were a bardic college, dedicated to the study and understanding of death and the reaction of the survivors to death. Initially, the organization had done much good work as counsellers, psychologists and medical researchers.
