About the book: 2011 / New novel of the famous cycle "Horus Heresy" for the first time in Russian! A split occurs on Mars - part of the Mechanicum adherents, including the supreme fabricator general, stand up on the side of Warmaster Horus, who bought their support by lifting the ban on the research and use of forbidden technologies. And then the comic aphorism of the Mechanicum - “Knowledge is power, beware of it” - will cease to be a joke and the red planet will plunge into the flames of civil war using the most advanced technologies, in including those that are initially beyond human control.
