All of the world is an adventure, and Aunt Queen, as she likes people to call her, has experienced alot of it. Old age has confined her to her home, and curio shop where she collects and sells cameos, books, and antiques.
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!"
