Confraternity of the Malignant Crab
Description: The Confraternity of the Malignant Crab is a secret cult of operating room surgeons and staff that is centered around the ritual sacrifice of cancerous human flesh. Acolytes of the cult can be found in many Western hospitals, including Japan. The cult has no formal symbol, but Confraternity cultists are understandably fond of crab imagery.
Well. The best thing that you can say about the Confraternity of the Malignant Crab is that they’re actually not utterly unreasonable, for a human sacrifice cult. Not actively malevolent, at least. It’s not like they make people suffer. Or at least, they don’t at the moment.
