Liber Imperium: The Forces of the Emperor Army Book

This book is an essential guide for anyone who wants to represent the varied Imperial forces that fight against and alongside the transhuman Space Marine Legions in games of Warhammer: The Horus Heresy. It contains all the rules you need to field the strictly-Loyalist Agents of the Emperor, from shining Custodes to shadowy Assassins, as well as the numberless ranks of the Solar Auxilia – who can keep faith with the Emperor or rally to the Warmaster.
