Knowledge Is Power. Merciless and pure in their search for data, the Skitarii - soldiers of the Machine God - march without emotion across the galaxy, tearing the secrets of war from the cold, dead hands of their enemies. Armed with the most terrifyingly advanced weaponry the Imperium has ever known, and driven by data imperatives that enhance their abilities to almost supernatural levels, the Skitarii are a post-human nightmare rendered in metal and flesh, collecting and analysing every morsel of information they can in order to fuel their thirst for ever more powerful tools of destruction. This 80-page, full-colour hardback book contains: A detailed, full background on the Adeptus Mechanicus, with information on forge worlds, motivations and history of the Skitarii and timelines giving you the lowdown on their place within the universe; Descriptions of the armed forces, vehicles and technologies of the Skitarii, with rules for each; A stunning showcase of beautifully-painted Citadel miniatures, with colour and iconography guides for every forge world faction. An Appendix detailing warlord traits, wargear and the Doctrina Imperative - a rule allowing Tech-Priests to remotely boost soldiers' abilities from their observing scryships.
