Breath

At the end of the Cycle, after another Silent is revealed, another character in the Face of God group is also revealed to match the Silent. This is the Breath of God.
The Breath of God is different than the other 16, as it is represented by a nonhuman entity. It represents the inner-workings of all things, the thing that permeates everything and connects it all.
In the Bible, the breath of life, "Zoe," is the element that is breathed into Adam to make him a living being. The Breath of God in the FOG universe gives life to all things. 
== The Highest Being in the Universe ==
The Breath of God isn't the "God" of the FOG universe, just another nearly omnipotent being.
