Immediately after the Massacre at the landing on Isstvan V, the surviving drop troops of the Salamanders Legion began a long search for their fallen primarch. There was no result. But they don’t know that, despite the fact that Vulkan himself wanted death, he was hidden away in a secret fortress by the evil jailer—his fallen brother Konrad Curze. Enduring endless infernal tortures of body and spirit inflicted by the Night Haunter, Vulkan unexpectedly discovers something that may be able to influence the war already underway.
