After centuries of exile, the necron lord Oltyx has at last been granted the thing he has always craved: the throne of the Ithakas Dynasty. Kingship, however, is not quite what he had hoped for. Oltyx's reign begins aboard the dying battleship Akrops, as it lumbers away from the ruins of his crownworld. Behind it is a hostile armada of unfathomable size, launched by the barbaric alien war-cult known as the Imperium of Man. And within the Akrops' sepulchral hold, an even greater threat festers: the creeping horror of the flayer curse. Faced with such overwhelming odds, Oltyx begins a desperate voyage into a darkness so profound that salvation and doom look much the same. If he and his dynasty are to make it through that long night, Oltyx will have to become a very different sort of king.
