Hell has come to Sygera. In the city of Moldevar, xenos aircraft battle the Imperial navy in the skies, and nightmares stalk the streets – creatures of metal, bodies crafted like skeletons with claws in place of hands, draped with the flesh of their victims. Against them stand a pitiful few defenders, among them Sister Hospitaller Lucia, who stands as a symbol of the God-Emperor for the people of Moldevar in these dark times. As the survivors rally around her, can Lucia lead them to salvation?
