It has been twenty years since Anvilgard – now known as Har Kuron – fell to the Daughters of Khaine, and a terrible secret waits in the occupied city's depths. Knight-Incantor Tivrain Greymantle is haunted by the call of her brothers and sisters, who Morathi-Khaine has imprisoned there, knowing that if they were killed or released, her perfidy would be revealed to Sigmar as he reforges their souls. Commanded by her superiors to forget their captured comrades, Tivrain resolves to do the unthinkable: defy Sigmar himself, brave the steaming jungles of Aqshy's Crucible of Life, infiltrate Anvilgard, and liberate them. Pursued by her superiors and on a collision course with a horde of Khornate Bloodbound, Tivrain and her companions forge onward, unaware that their mission – and destinies – may prove more treacherous than they could have ever imagined.
