Lost my patience while reading topics & finally registered for some comments! Actually, one comment for now, about "elju technology". I tried hard to stick to the explanation which also corresponds with ideas and themes already mentioned in both trilogies.
1. Guys and girls, there is no book without structure, without formal table of content, right? And every book appears rather through text destruction than it's creation. So we should be very careful with comprehending "book" as a blunt object and denying it all properties of a subtle process, otherwise we will blind ourselves to the certain ideas and guesses.
2. Incariol was kinda direct about nonman personal integrity — there is no such thing anymore. Also, "Four Revelations of Cinial'jin" shows us a river of images instead of a personal dialogue. So for me it always looked like nonman can (and will) memorize everything he experiences through the countless ages, but at the same time will gradually lose every control over both old and new memories. A dark undercellar of his mind is totally fine, it's large enough to keep all that heroical, dull an villanous deeds even for hundreds of thousands of years. But a candle of nonman's mind to light that enormous and growing dark space... Let's just say it's a dim one and it will never get brighter.
3. We already saw an example of a conditioned mind and I mean that awesome probability trance. Practically, it's a pocket analytical department with IT-grade tools but for a cheap price of a timely and proper education.
So, here's an idea (as an intersection of all these three paragraphs).
What if "elju" is just a conditioned passerby, who do not possesses even a bit of nonman's real and personal history, but who somehow can enchance nonman's cognitive process in a specific way through simple or complex technique? So the "book" (human, sranc, etc as a companion to nonman) appears when "text" (nonman's memory) is cut in a specific way by an editor (nonman and his companion). Of course, there remains a question about who defines that specific way...
I stand for "no one" as an answer. And that's why i have a sinister shivers here, lol. Just imagine a rotting, colossal, self-encumbered, unstable, dying something in an every nonman's psyche, which sometime conditions passerby humans or even srancs to recollect it as a something new and lesser, but stable and viable. Maybe after all the inchoroi and their circumspect creations are twice less ghastly then their accidental ones.
