Dark Mechanicum

The Dark Mechanicum, also sometimes referred to incorrectly as the Dark Mechanicus, and who refer to themselves as the “New Mechanicum,” is a sect of traitorous Tech-priests, members of the Collegia Titanica and Chaos Knights of the ancient Mechanicum who have become Hereteks in service to Chaos. They willingly swore their loyalty to the Warmaster Horus and the Chaos Gods as the Great Crusade came to a close and the terrible galactic conflict known as the Horus Heresy erupted in the early 31st Millennium. After the Horus Heresy ended in a pyrrhic victory for the Imperium, the traitorous forces of Chaos that had served the Warmaster were driven towards the Eye of Terror during the brutal military campaigns remembered as the Great Scouring. The Renegade Tech-priests of the so-called Dark Mechanicum were also driven from Mars by the resurgent Loyalists amongst the newborn Adeptus Mechanicus.
