A Tech-Priest of the Dark Mechanicum.[4b]

The Dark Mechanicum, or Dark Mechanicus[7], referred to by themselves as the New Mechanicum[6], is a Chaos-affiliated counterpart to the Adeptus Mechanicus. Its origins trace back to those who pledged loyalty to Warmaster Horus at the end of the Great Crusade. The Dark Mechanicum serves as a dark "mirror" to their counterparts within the Imperium.


Horus gained the loyalty of a sect within the Mechanicum after promising them STC technology gained from the worlds of the Auretian Technocracy and the opening of the vaults of forbidden technology on Mars. 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 servants.[4b]

Having won over many of the Mechanicum's Priests, Horus encouraged his new allies to dabble in previously forbidden technologies, gradually enticing them to the powers of Chaos.[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.[1] With the defeat of traitor forces after the Battle of Terra and the subsequent Great Scouring, the Dark Mechanicum fled into the Eye of Terror with their Chaos Space Marine allies.

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 Hell-Forge worlds such as Xana II.[3]

During the Thirteenth Black Crusade, the Dark Mechanicum began invading Imperium worlds that were devastated in the aftermath of the Great Rift's creation. Their targets are not picked at random, however, as the Dark Mechanicum are searching for ancient archeotech that will help them complete an unholy weapon of war and terror whose like has not been seen since the Dark Age of Technology.[5]
