Traitor by Deed written by Ben Counter
In the galaxy-spanning conflict of the Indomitus Crusade, an Imperial force is sent to bring the Emperor’s rule back to the isolated world of Kepris. They are the Soul Drinkers, Primaris Space Marines bearing the name and heraldry of a Chapter lost to Imperial history.
This strike force finds the planet ruled by a bloodthirsty cult – its cities seized and loyal shrines under siege by the mysterious arch-heretic Yeceqath, the Voice of All. Striking swiftly and with cold fury, only the Soul Drinkers can unravel the heretic’s foul machinations and break Yeceqath’s hold over the world… but there is more at play here, as one of mankind’s oldest enemies lies at the heart of a conspiracy to see Kepris fall, taking the Soul Drinkers with it.
