Flayed Ones are Necrons who have been infected and succumbed to the Flayer Virus of the C'tan Llandu'gor, a Star god who inflicted Necrons with it as retribution for being obliterated by them. As a result the virus drives them insane with a hunger for blood and gore. They wear and decorate themselves with the skin and body parts of their opponents. Driven out or destroyed by their fellow Necrons for fear of the virus, these monstrosities congregate wherever bloodshed is to be had.
