Crackpot time! With special love for procrastinators!
(sorry for ads style and far-fetching, btw
for the first - I just couln't resist playing a consult enlister
for the second - trying to tie all things together is my weakness)
1. Human conciousness is interruptable, so when they go to sleep, they actually die and cease to be. Once awoken, it's a new person rebuilt from most "important" memories and it have a day or so to collect new memories, to reassign memory importance and to die again. That's why people hate their lives and have difficulty of changing them, that's why despising someone in evening rarely survives after morning. The whole "identity" is too self-smoothed to produce something really new, changing, important! But that's exactly what makes people a perfect garden for gods to grow souls (ppl are complex enough to sin and to be punished for sinnery, but are also too weak to achieve salvation or to rebel higher beings).
2. Inverse Fire can fix that ugly flaw! Sleep begone! You conciousness will never be interrupted again, so there is no need to rebuild it. Your personal measure of "darkness that came before" will decrease, though won't be terminated entirely. Morning will not melt your evening thoughts and plans never ever again. That will make you a monster in people eyes, and will make them trivial teknes in yours. You will fight the gods and the reality itself (these are the same thing, btw). Though you lose the world, you shall win your soul.
3. Nonmen are men whose rebuilding is, let's just say, especially complicated. Inverse Fire can fix that too! Over time you will became much more... intact, dear cunoroi, because morning will not shatter your evening identity under your memory weight. Through centuries you will finally recollect yourselves, you will remember forever and you will never forget.
So, what was I sneaking up to?
A) All intacts are consult products. They are mentally "healed" by the same plot device (tekne stuff) which "broke" them at the first place. They are like Kellhus to dûnyain, something greater & something new, pure badass & dangerous.
B) The whole "erraticism" of consult nonmen is a matter of human perspective (f.e. Sorweel's), who just can't differentiate between sane nonman with evolved psyche and insane nonman with haywire psyche.
C) There is no eljus in Golgottherat or Ishterebinth for they are obsolete now. Nil'Giccas was not only the last king of the nonmen, but one of the last erratics as well. >:з
