Book excerpt: Chaos Space Marines are feared for their savage brutality. When ungodly visions drive Dark Apostle Jarulek of the Word Bearers to the unsuspecting Imperial planet of Tanakreg, he and his dark force attack without mercy and brutally enslave the population. With the planet in ruins, they set their new slaves a mysterious task: to build a hideous tower of monumental proportions. What is Jarulek's vile purpose, and can he achieve it before the Imperial forces arrive to reclaim the planet?
