The Children of the Forge were a race of sentient machines, also known as Silica Anima, which are considered Heretical by the Imperium. The Children of the Forge were created and lead by their "Father", Rangor Malatron in support of the Cerean Brotherhood during their attempt to secede from the Imperium of man. At the end of the Cerean Crucible the Children of the Forge were hunted down and annihilated by the agents of the Inquisition and the Adeptus Mechanicus.
