|This article is about the Dark Mechanicum, for the Novel by Ben Counter see Dark Adeptus (Novel)|
Horus gained the loyalty of a sect within the Mechanicum after promising them STC technology gained from the worlds of the Auretian Technocracy. In addition, Horus's emissaries and spies told the Tech-Priests that the Emperor planned to steal the secrets and technology of the Martian Mechanicum and even eventually enslave the Tech-Priests. Lastly, Horus used the ideological schism within the Mechanicum, between those who believed the Emperor was the earthly representation of the Omnissiah, and those who still thought such a figure was entombed on Mars, suggesting it was the Emperor himself who had presented himself as their god in a scheme to make him their servents.[4b]
In the resulting Schism of Mars, the Dark Mechanicum led by Fabricator-General Kelbor-Hal supported the Warmaster during the start of the Horus Heresy and were present on Istvaan V where they used dark and forbidden knowledge against the Loyalist forces.
In the 41st Millennium, the Dark Mechanicum are still active, utilizing massive, daemonically corrupted Titan war machines of the Traitor Titan Legions against the Imperium and producing infernal weapons and Daemon Engines from the world of Xana II.
