The Final Understanding

== Disambiguation ==
The Final Understanding is a metaphysical term that refers to the last piece of knowledge that humans will attain to be able to answer every question in the universe. In the Face of God, it refers to a few pataphysical/4th wall ideas in the series.
== Storytellers Are the Doors to Other Realities ==
One fun idea that may be hinted at or shown outright is the idea that anyone who writes a story is actually penning out a new reality; therefore, storytellers are creators and doorkeepers of other realities. This is hinted at when Stacey tells about her story she's writing about a guy who doesn't know what he wants to do with his life--she is writing a story about the author's life. As she writes, his life moves on. In this way she's the doorkeeper of his reality. The FOG series may take this further by actually having their be portal doors in universe to go to other realities.
=== INFP's Specifically Are Doorkeepers ===
According to the Meyers-Briggs Type Indicator, there are 16 basic personalities; this can be used as a way to observe people. The 16 concept in the FOG is based on this, and the one connected to Stacey, the INFP type, is described as being dreamy and imaginative. Any one can write a story, however their imagination leads to a certain flavor of story, and their ideals are often unrealized due to them being unrealistically fantastical, creative, or moral. INFP's may be established as the doorkeepers in cannon. The idea here is that the reason INFP's can have such idealized and unrealistic ideas of reality is because they were meant to use those ideas to create new realities with free reign--being the storytellers and then gateholders of those realities--and thus their ideals are good ethical frameworks for better worlds.
== The Cessation of the Yin and Yang ==
One idea surrounding the Cycle, the opposite connection between the Silent and the 16, and the God Saga War is that there is a yin and yang like dynamic, a devine feminine and masculine, that serves as the framework for the Silent/16 and also serves as the main impetus for the civil war that ensues during the God Saga.
In regard to the civil war, it may be both parties are seeking to attain their opposite values; that, naturally over time, the universe naturally goes back to a state of Yin and Yang, and thus the power achieved at the beginning of the God Saga is reversed. To put it more simply, when the 16 defeat the Silent, rather than join with them, their incomplete nature becomes apparent, and Stacey, Eli, etc. seek to attain that other half; in Stacey's case it's to go back to where she was with Rose, who is her divine opposite, or at least represents her divine opposite. The opposite side--imagine it was Thomas, Amos, and Eliza for illustration--also seek their divine opposite. The doesn't seem like a problem considering all the power that everyone has. However, the problem occurs when each of the 16 realize that their opposite can't exist in the same universe as them, because if they regain all 16 opposite forces (represented in the Silent), they will have to be in war...again...eternally. So the Ocham's Razor approach is for them to just destroy or prevent just one of the 16 from having their opposite. Perhaps fifteen could team up against an unpopular one and all fifteen can have their complete nature, with just one suffering. 
Well that seems like the obvious answer
== The Meaning of the "Face" Of God (Possible) ==
This is an idea for the 
paramouaxiom encapsulating the very meaning of the entire series.

When the Dreamers are defeated by the humans, the plot reveals that every human, including the initial sixteen, had to go through their life on earth in o
rder to become a specific type of god--human ones. The idea here is that humans once existed before the Silent, and before the initial creation of humans as we know it, and they were gods, but the knowledge they had showed them that they couldn't know everything because they hadn't experienced the lack of everything. This experiential knowing was only possible if they had the traits opposite; for example darkness, without light and further, they had to know what it was to not be able to create light at any given moment
