Very compelling stuff, Madness, though it seems you've linked the same thread twice. If there's another, I don't immediately see it in a search.
I've reached several similar conclusions as those listed in that essay, though I find the ramifications regarding the Thousandfold Thought particularly interesting for the purposes of this thread. Taking it a step further from an attempt at rewriting reality (Dunyani sorcery?), what if the Thousandfold Thought has indeed birthed another god - Kellhus. That the Zaudunyani's belief that Kell is not simply a voice of the God, but the divine himself, has in essence made it so?
While I poorly understand the metaphysics of the No-God, it so far seems to me to explain a likely strategy, a new "god" as a counter to the No-god in the absence of the Heron Spear or other Inchoroi weaponry. That Kellhus might strike at the No-God in the Outside, where it is potentially more vulnerable than in the physical, and where he now has considerable power drawn from the Zaudunyani.
What it does not explain to me, at least at first thought, is Kellhus' apparent indifference to the hostility of the Cults.
That essay has given me a great deal to consider as we await the Unholy Consult. Much obliged.
