Liber Mechanicum: Forces of the Taghmata Army Book

Warhammer: The Horus Heresy – Mechanicum
Forged in logic. Powered by the Omnissiah. Feared across the stars.

The Cult Mechanicum wields the most advanced and arcane technologies of the 31st Millennium. Guided by Tech-Priests who have surrendered flesh for function, their armies march to war with relentless precision—battle-automata, war engines, and cybernetic soldiers bound to ancient codes and the unknowable Machine God. As the Horus Heresy engulfs the Imperium, the Mechanicum arms both Loyalist and Traitor alike with weapons that defy reason.
