Animating Intelligence from the First Age
I AM was a First Age synthetic intelligence, capable of free will and independent thought, and further capable of massively multiplexed intelligence, allowing it to simultaneously converse with and contemplate almost the entire population of the world simultaneously. It served as a communications network as well as a companion to most of the world, serving as a middleman for cashless banking and commerce, and a personal companion and friend to most of the mortals of the High First Age during its heyday.
Thought to have been destroyed during the Usurpation, I AM (or at least a fragment of his original consciousness) was found within the Hall of the Coiled Sun by the Circle of the Phoenix. He is now assisting the Circle, providing them with knowledge of the First Age and a means to communicate great distances via their new suits of power armor.
