Well, I've actually "been around" since the days of the Three-Seas board, just never post much.
The play of Fire is probably close to the mark, regardless of what actually occurs in that hell. An anchor for the reader.
The analogy for cold works, though cold if often associated with numbness, and peace/quiet, while for me fire is more easily associated with suffering and screaming agony. I can't imagine a more horrific way to spend eternity, endlessly burning in a fire...
I also think you might be combining 'The Void' and "The Outside'. The Void is presumably a reference to space, while The Outside is the spiritual realm. There are many different kinds of 'Outsides', as many or more than the number of Gods, and I associate the oblivion/nothingness that the Nonmen/Titirga seek is someplace untouched by those entities, a place of nothing.
I agree that the idea of the Void (space, as we call it) and the Outside (eh, I guess something like Heaven, Hell and Purgatory) are actually kind of mirrors (maybe?) of each other. In the sense that the Void is the nothing outside the physical realm (ok, not actually nothing, but something very much like it, conceptually) and the Outside is the nothing outside the spiritual realm. Planets (well, matter, so stars, etc.) are the breaks in the Void, the Gods seem to be the breaks in the Outside. I guess that what leads me to conflagration the two together to put meaning to what Inverse Fire could mean.
Reminds me of Adam/Eve and the tree of knowledge.
Exactly, knowledge that really was not supposed to be known, as in, knowledge you can't handle knowning.
The choice between nothing, and an eternity of peace, seems like a pretty easy one as well, especially if the 'oblivion' gambit if not a sure bet and you end up burning forever anyway.
Well, there are seemingly three options when your soul passes to the Outside:
Salvation - you soul is coddled and accepted by a god. Seems decent.
Oblivion - your soul just slips through a crack in the gods and is gone. I don't know how that seems, kind of like a loss though.
Damnation - your soul sits between the gods, forever in purgatory and probably pain. Seems pretty bad.
I think the Consult, in light of the Inverse Fire, know they can't gain salvation. They are unsure if they can achieve oblivion (seems to take a worship system). What seems provable to them is either accept damnation or go about sealing the world. Not hard to see why they take that course really, considering.
