Few have ever seen the incomprehensible entities known as Trench Dwellers, but their lethal biomechanical machines remain, guardians of a long-forgotten empire.
In the dawning of time, a mighty civilization, mystical and alien, flourished in the oceanÃ¢??s unseen depths. Their day has passed, but their hidden metropoli linger on.
From an episode of Justice League Unlimited:
The God of War creates a giant, unstoppable robot (golem, animated armor, etc.) as a weapon for one side in a civil war; his purpose is to prolong the war and create suffering and war among humanity.
Quote from Ares in that episode, which would go well with this idea: "That's all you mortals are good for! To fight and fight and fight until there is nothing left but charred land and blood and bones, and to end it all and then start again with the next generation!"
