OK I finished the books a while ago but there is something that has bugged me and am trying to get clear in my head...
Does the Outside exist all through the universe, its not just localized to the Earwa world?
This is a very good question and one that really cuts down into what an Eärwan soul actually is. I'd invite you to read
my recent topic in this subform but it is overly wordy,so I will attempt to condense it's broad implications down to just address your question.
The answer, simply, is yes. But the answer is also, simply no. Because the Outside is not a "place" in the spatial sense. The Outside is plausibly an inter-psychic place. That is to say, it is a place that connects "souled" things and exists only in the space of those souled things. So, the Outside is everywhere, as it is no where. So, this is why it cannot be run from, because it is a part of you and you bring it with you where ever you go.
If yes to above then the the Hundred Gods ( Ajokli, Yatwer etc...) must exist all through the universe also?
No, not really. I've hypothesized that each "world" is something of an "island" in The Void. As an inter-subjective space though, everywhere has a "space" that is akin to the Outside, but as an inter-subjective space each is built subjectively. So, on Eärwa, the Outside has it's particular character, as the Outside in other places will havee a different one. What isn't different is The Cubit, because that is like a law of physics in Bakker's universe. So, sins are sin everywhere, but the character of the resultant Outside is not because that is built from the subjective framework of those that make up the inter-subjective space.
I'll field the other questions soon, just a little low on time at the moment.
