History

The Engine of Negation is an extremest sect of the Cult of Troniac, founded by General Zarlok, after being accidentally rescued from exile.  Zarlok was a robot built specifically to defeat Troniac during the 1,000 Years war, and as such was both sheltered against evidence of the abuse of robots in the Empire of 1,000,000 Suns, and protected with the Nalaxian Code. 

Only when directly confronted with the facts of that oppression via a memory device surreptitiously by one of Troniac's agents, did Zarlok relent and support robotic liberation, albeit after the conclusion of the war.  This was the critical event that led to the founding of the Engine of Negation.

So great was Zarlok's rage, at being systematically deceived, that it detonated a powerful Neutron Pulse Device on Artanis 4, killing millions of civilians.  After this, the Empire exiled Zarlok, by beaming its program into "uninhabited space", only for it to be received thousands of years later, on Earth (at the close of Era-0).  After declaring war on humanity and all other organic life-forms, and spreading the creed of Troniac throughout human space, General Zarlok decided that the time was right to found an organization dedicated to wiping out organic life in the galaxy.  This organization was the Engine of Negation. 

Luckily, for humanity, the Planetary League's efforts against The Engine were effective enough to prevent it from achieving its goals.  In particular, the Department of Artificial Justice (originally founded by the United Nations to combat Zarlok's villainy) was tasked with hunting down and eliminating the Engine.  The Tardigrades also had frequent clashes with the Engine of Negation, as did the Interstellar Navy, and various Planetary Defense Forces.

The Engine of Negation continued its activities until the War of the Gods, when Troniac returned to the galaxy.  The Engine of Negation joined with the regular forces of the Cult of Troniac in order to combat the Holy Empire of Man.

Tactics

Among the most disturbing weapons of the Engine of Negation are the Maenads of Troniac, intelligent life-forms infected with virobots designed to send them into a berserk rage.
