Kophos

Kophoses are pain purists who believe that screams and tears detract from the experience of suffering. These velstracs gouge out their eyes and cut out their tongues to make such outbursts impossible, covering the empty cavities with patches of their own skin or spiked lumps of metal, though they are still disturbingly able to see and speak. Beyond these self-inflicted injuries, they resemble typical humans, though their bodies are covered in countless gashes and scars that slowly, gruesomely heal themselves. They wrap themselves in dozens of barbed chains.

Kophoses consider it their purpose to find mortals who either inflict physical suffering on others or who are plagued with constant pain due to medical conditions and teach them how to be silent and stoic in their agony.
