Publisher's Synopsis
Untold billions curse the name of Horus as an arch-traitor, one who has brought strife to the galaxy on an almost unimaginable scale. However, there are some who whisper instead that the blame lies with the Emperor himself. Years after retreating from the Great Crusade to unknown endeavours beneath the Imperial Palace on Terra, he now wages a very different kind of war deep within the ancient eldar webway - a war against all the daemonic forces of Chaos.
