Adeptus mecanics

The Cog Mechanicum, icon of the Adeptus Mechanicus

The Brotherhood of the All Seeing Eye was an order of archivists within the ancient Mechanicum during the time of the Great Crusade and the Horus Heresy that resided on the Machine Cult's homeworld of Mars.

They witnessed the destruction of countless forms of priceless knowledge that had been maintained or recovered by the Mechanicum from Mankind's lost past at the hands of the Dark Mechanicum during the Martian civil war known as the Schism of Mars.
