Dark Mechanicum



The Dark Mechanicum is a sect of Tech Priests of the [Adeptus Mechanicus]] who swore their loyalty to the Warmaster Horus as the Great Crusade came to a close.

Horus won over the loyalty of the adepts after promising them STC technology gained from the worlds of the recently subjacated Auterian Technocracy. They supported him during the start of theHorus Heresy and they participated in the Massacre of Istavaan V where they used dark and forbidden knowledge against the Loyalist Imperial forces.
