Age Of Darkness: Liber Imperium (English)

Outside the loyalist Space Marine Legions and the Cult Mechanicum, the Emperor wields forces which are loyal only to him. The Legio Custodes guard the Emperor's person, while the Sisters of Silence stand watch over the Black Ships. The Solar Auxilia are the elite spearhead of the Imperial Army, exemplars of mortal soldiery, while the Divisio Assassinorum is the Emperor's culling blade, aimed at the neck of any foolish enough to imperil his grand dream of Unity.

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.
