The ergodic, Fortean fugue Whom Gods Would Destroy: An Occult History of the First World War concludes in its third volume, Armageddon, chronicling the twilight of the Great War and the Nine Giants' pilgrimage to the Holy Land, where the armies of the world and the cosmos converge on the hills of Armageddon.
