The Voroshk are a family of sorcerers who have taken over the world referred to as Khatovar. Their earliest ancestor came into power around the time that the Shadowmasters took over Hsien. He had tens of children, most of which inherited his powers to greater or lesser degrees. At the time that the Black Company comes to Khatovar, their are hundreds of living Voroshk, most of whom have limited power. They are characterized by their extreme arrogance and sense of entitlement. They wear voluminous black clothing which conforms to their bodies and responds to their thoughts, protecting them from most bodily harm. They use devices called rheitgeistiden for transportation.
They befriend Lisa Daele Bowalk once she arrives in her world and aid her in achieving vengeance on One-Eye. This draws Croaker and his friends to Khatovar, whom they plan to steal knowledge of Shadowgates from.
Croaker captures one member of the family after killing Lisa Bowalk and tricks the others into blowing up their own shadow gate. This floods Khatovar with Shadows and nearly causes the extinction of people in the world, particularly the Voroshk who must battle them. Four more members of the family join the Company willingly to escape the destruction in their world.
Several of their members becomes associates of the Black Company, and one even falls in love with Tobo.
