The Lichemaster Heinrich Kemler is bound by his bargain with the Choas Gods brokered by Lord Krell, Champion of the Chaos Gods, and his champions Captain Ranlac and Lieutenant Mikeal Jaksen. He is only kept alive and sustained by the lives of their victims, another day or a magical boost for every death.
