To me the No-God's questions seem to be basically the manifestation of it's "hunger" to BE, it's simply functioning as it must in the only way it can due to it's construction/components and it's pre-determined programming. We know Kelmomas' brain is different from others' which is the reason he is a viable Insertant. The No-God's questions sound like they're from one twin to the other. Without the constant input from the bodily-active/first-person twin's thoughts, the second twin is left baying at the gates so to speak. "Neither of them" can know that they "both" suffer the same fate. To THEM (if such a statement is applicable) I assume it feels like they've been cut-off from one another, this being the cause of the No-God's "hunger", the desire to be whole again... TO BE.
Parentheses because we know they constantly swap; "Kelmomas" as watched/Object, "Samarmus" as watcher/Subject. Now they're at once both, and neither of these things. Zero and One.
I'm sure there was a lot of discussion about it already, but there's clearly something up with the Judging Eye and the No-God. Scenes where TJE opened in the Great Ordeal mention "Sranc squealing in the black" and the like. Most believable for me is that the Judging Eye only exists due to the No-God existing (and thus it exists/has existed retroactively). Some of you would probably be able to conceptualize it better, but for lack of a better way to share the thought I'll do my best.
TNG collapsing of Kel/Sam certainily ruined the God of God's cycle, it glitched the system and "woke" the God. We know for sure that only women who give birth to still-born children have TJE, but I think that twins are a part of that requirement as well. Because Mimara would have the twins she carries, she has TJE and thus has had/will have it her whole life... maybe not ONLY because one would die, but SPECIFICALLY because of that circumstance in addition to the No-God doing its subject-object collapse. I think, due to souls sharing the same space, that the collapse of Kel and Sam somehow also happens to Mimara's twins... blinding the Judging Eye in the same way that we're blind to how our brains work. Seeing, feeling, understanding how our brains do what they do is not a function of our brains, and I believe here that seeing, feeling, understanding itself is not a function of the God.
What could this mean? Hell, anything. But sounds logical to me that the world being Shut and the lack of new (live) births makes sense if you are willing to entertain the thought that at this time (post-Resumption), the "shared space" that's orthogonal to Bios, has collapsed into ONE place... ALL souls, or at least the remaining/unclaimed Portion were born into Mimara's baby?
Can't forget to include!
The Ark, The Inchoroi, The Progenitors - Okay, I am going to go ahead and jump into the clearly less popular opinion and side with Ajencis, that genius dude who was like "Wait wtf? There's no way they flew to other planets!" due to the identical locations of stars when charted from different corners of the World. "The stars would move relative one another were they not uniformly embedded in a sphere hanging a fixed distance about the Sky."
....Okay, yeah Ajencis might not be aware of Tekne and it's possibilities... but I am far more inclined to trust in him (and his statement about the stars/sky/universe) than the Inchoroi. In Ajencis' Glossary entry in TUC, this line caught my eye in regards to the discussions in this thread: "In fact, he observed that most individuals posses no criteria whatsoever for their beliefs" - which I include here specifically because the Inverse Fire is seemingly ALL the Inchoroi are basing their beliefs on (that and whatever "programming" their Bios was crafted with). The Mutilated claim they "outlived their origins" or some such, but who is to say that they ever knew their origins? They are a creation, that much is obvious... but truly, what reason have we to believe in "Progenitors", or believe that a weapon race like the Inchoroi would A.) Tell the truth if they knew it or B.) KNOW in the first place?
The Inchoroi are doing no more or less than what their Goad(s) call upon them to do - they create the No-God, they wake the God. Who wants to wake the God? The Vision/no-haloes Kellhus! (Which I think is Outside-Kellhus, but could certainly be a lot of other Things.)
The tapestry thingy that was flashing a code of sorts which only WLW/Sorweel (right?) and Kellhus could see/read = I can't help but think Kellhus made the Inverse Fire.
Got way too much to add as usual and this is more than enough for one post.
ETA: There's no real need for "Progenitors" or actual other worlds/Grounds from my perspective. The Inchies are probably deceived. The Nail is where the Ark came from and it could be the Outside as much as it could be a Wormhole, or from Earwa's past/future, I hope we find out!
