After the destruction of the Monarchy and the Emperor's censure of the Word Bearers Legion, Primarch Lorgar spent many years searching among the stars for the universal truth of the cosmos. When he eventually arrived to peer deeply within the Eye of Terror, he found that the Eye stared back. Now, under the guidance of the demon Ingethel, he undertakes a sacred journey into the very heart of Chaos and sees that the entire destiny of humanity and the Imperium can rest only on several key events. As the Great Crusade burns itself in the flames of betrayal and lies, Lorgar ponders the cost of his own ambitions and begins the path to eternal damnation.
