Liber Questoris – Knights and Titans Army Book (English)

During the Horus Heresy, the ultimate engines of war deployed by the Imperium were the towering Titans and the noble Knights—massive war machines capable of leveling cities and annihilating entire armies. Bound by solemn oaths to the hosts of the Great Crusade, the pilots of these mechanical giants followed their allies into the inferno of civil war, fighting for either the Emperor or the Warmaster.
