A rare post-Heresy Primarchs story, Gav Thorpe’s Shadow of the Past takes place on a moon in the Eye of Terror, where Dark Apostle Kalta-Ar of the Word Bearers supervises the building of a grand monument to the dark gods. Protected from the dangers of the warp by ritual means, the Word Bearers nevertheless find themselves under attack by something that bleeds out of the shadows to rend and tear. When they at last bring their monstrous attacker to bear only to find their weapons useless, Kalta-Ar entreats the daemon primarch Lorgar to aid him and his surviving warriors.
