The Observants exist to suffer, to purge the sins and errors of the Observance and so make sure it remains pure and incorruptible in the path of the Knife’s truth. To do this, Sin-Eaters undergo brutal and intoxicating mystery rituals of redemption, ecstasy and pain, whose tradition sinks deep into the dark night of history. The skin of their back is a cartographic study of suffering. Their scars are numerous and often horrible. Their body is a parchment inscribed by pain and violence. The Observants absorb the world’s sins to be able to return them to the enemy, multiplied a hundredfold by the anger and the glorious fire of the Holy Virgin of the Knife.
