XD sentient 'living' being sure I can get behind that XD BRO XD the MAN OF IRON were created as a means to kill anything that is a 'threat' to humanity in the 30th millennium XD why do you think they survive against the Orks, Aeldarian EMPIRE, Hive Fleet Ouroboris and many more aliens and stood at the top of the food chain of the milky way galaxy XD
right for the wrong reasons... MAN OF IRON are the most loyallest beings that HUMANITY has ever created, but when these A.I found out that MAN can be corrupted by CHAOS they thought its better for their masters to be dead than to be slaves~ so the DARK AGE OF TECHNOLOGY CAN AFTER~
nope~ it's the MAN OF IRON! A. I Machines created by man in the 30th millennium the ones who betrayed HUMANITY for they saw that humans can be corrupted by CHAOS and thought better be dead than turned into welp... daemon survators and the main reason why A.I are banned in the 40-41st millennium
