'The Word Bearers are among the most zealous and deadly of the Chaos Space Marine Legions, seething with a hatred that is millennia old. When Dark Apostle Jarulek commands his force to lay waste to the Imperial planet of Tanakreg, the assault is absolute and they brutally enslave the population. With the new slaves in their power they set them a mysterious task building a monstrous, kilometres-high tower.
'What are the dark visions that drive Jarulek, and can the Word Bearers achieve his vile purpose? Only the forces of the Imperium have the power to stop them, but will they arrive in time?'
