Legitur is a world devoted to the sacred writings of the Imperial Creed. Endlessly producing mountains of scripture, it considers itself an exemplar of piety. But there are deep secrets here – undreamt of by the ruling Ecclesiarchy, hidden amongst the shadows of the towering paper hives – and a being who was born of these secrets.

Cerastes, Dark Apostle of the Word Bearers, has returned to the world he once called home. Though his host has been crushed by the fearsome Palatine Aesura and her Sororitas of the Order of the Thorn, Cerastes’ dark ambition is undaunted. He will have his revenge. He will resurrect the Eightfold Bane. And he will convert the world he despises to the worship of Chaos. Legitur is about to receive the Word, and it will burn with the fires of revolution.
