Word of Horus' treachery escapes Isstvan III and now the Legions loyal to the Emperor mobilise to make Horus and those who follow account for their crimes. However the depth of the betrayal is yet to be revealed.
Most of the book is presented as a record written by "A.K." shortly after the Horus Heresy. The first part of the book contains a brief summary of the Unification Wars and the Great Crusade, the raising up of Horus as Warmaster, the Battle of Isstvan III, and the Imperial response to that atrocity.
