Well, perhaps not the most original, but always since I finished The Great Ordeal I've had this thing, perhaps a strong suspicion, that the Great Ordeal is bound to failure, and Kellhus has known it from the get go. Let me explain: As far as we know, Salvation is the principle that motivates his actions. Broad as it is, it could be or not interpreted in the same way the Inchoroi do. If Kellhus too, shares the same beliefs in Salvation, he may well be laying the ground bare for the arrival of the No-God, so this time his victory is undisputed and pretty much guaranteed. May as well be wrong, of course, but that's what my gut's telling me.
