Skarku is a Slaughterpriest, with knife-sharp teeth, serving the Bloodwrought under Ghaar'eth. After defeating the Arcanites in the Gargantua Ridge he was consulted by his warlord on the meaning of the storms that followed them. Skarku answered that it was a portent for further battle summoned by Khorne. He was then told to stop the dark feast and prepare for battle. Before that he took a ruby-red skull and a feathered war-mask and tied both around their belt.
