All souls connect to the Absolute and every man could feel the presence of the No-God but the Hundred were blind to Mog-Pheru. This is going to come down to exactly how the Judging Eye functions and how the No-God's powers operate. How can a being be sensed by every living man and blind the gods? How does that work if we're all connected to the Absolute? From exactly what vantage does the Judging Eye see and what does that mean about the nature of salvation and damnation? About the connection of the Hundred to the Absolute and who decrees damnation and salvation?
I think there's a couple more pieces of the puzzle to pick up.
Well, it could be (and I'm just making shit up here, I am no doubt wrong) that the No-God is actually "closer" to the Absolute than any of the Hundred. This could be because while each God is separate from The Absolute, the No-God is simply an
inversion of the Absolute. There are no doubt a ton of gaps in here and I am not trying to make it seem like I have all the pieces of the puzzle, let alone put it together.
However, the Gods being apart from The Absolute (Zero-God, Solitary God, Cubit) makes sense that they hunger for damnation though, if we consider, as you say, all souls connect to the Absolute. If the Gods were cleft from the substance, or Being, or something, of the Absolute, then we might imagine they are attempting to reconcile with it, or are fueled by it? If a soul reaches the Absolute (salvation?), it is beyond the reach of any of the 100, i.e. not food for a God. However, if they are damned, they get caught by a God and are "food."
