Men of Iron

Men of Iron were mechanical AI warriors made sometime during the Age of Strife. Rebelling against their human creators they brought much of mankind's great works crashing down. The demise of the Men of Iron is unknown.

Colonel Commissar Guant found an apparently intact STC device on Menazoid Elipson, a Chaos corrupted world dotted with vast Chaos pylons. Certain Imperials would have used it to their own ends, mainly to create a robotic army with which to overthrow the Impeium, however Gaunt had it destroyed woth grenades, after the first two produced Men of Iron were tainted by Chaos.
