With this book you can field the elite troops of the Imperial Army, second only to the Legiones Astartes themselves, The Solar Auxilia; the towering war machines of the Questoris Knights, each of which can also be added to other Loyalist or Traitor armies as Lords of War; and the endlessly varied armies of the Imperialis Militia and Cults, whose versatile Provenances of War rules can be combined to create countless armies – from a cyber-augmented warrior elite with advanced training and technology, to a feral mutant horde marked by the warp itself.
