[QUOTE=Shienvien]Seeing how his mother and him share the trait, making it another mutation could work, perhaps (as far as I am aware). ASTA considered it interesting, from what I know.[/QUOTE]
It could perhaps be feasible to say that whatever condition causes the souls of the del-korm to disintegrate upon becoming disconnected from their body would also allow them to cause partial (since if they went around and consumed the entire souls of beings, I sincerely doubt they would be left alone for long) disintegration of others' souls and be capable of assimilating them into themselves. If that is the route taken, all that would really be left would be to determine how - and when - this ability is used in practice.

[QUOTE=Shienvien]How is the drive to do good orientated? Solely according to the specific individual's understanding of good and evil? (With deities getting a pass from the usual consequences of being judged by others, since their alignment is predetermined ... meaning that they can have rather twisted perception of good and evil with little repercussions aside of the disdain of fellow deities.)[/QUOTE]
A being driven to do good or evil are driven to do so based on their own perception of what those things imply, yes. A god or angel can easily be perceived as evil by others, and as a matter of fact a demon can actually also be considered good. To say that there are no repurcssions from being judged by others' view on what good and evil are would be inaccurate, though... they do not possess the Seed opposite to their own alignment, which means that this cannot store the "karmic energy" generated by their actions... but this "energy" (in lack of a better term) is still generated. I'll refer to a phenomenon mentioned a long time ago called the Flood Effect, and leave it at that.

[QUOTE=Shienvien]- I recall you described Rilon as not understanding good (?), and being unable to act good no matter what he wanted (though it could be just the drive to do evil overpowering his conscious thinking).[/QUOTE]
Beings innately bound to one alignment and excluded from the other are incapable of comprehending the very concept of their opposite, and are generally confused by arguments based on things like that. Granted, what the opposite of their alignment entails is still determined by their personality so the good that Rilon can't understand might not be the same as a demon can't understand. Eh, it's pretty circumstancial, really, but a pure-aligned being will always try to explain others' actions based on its own moral perception, and it will be confused and potentially enraged by actions that it cannot fit into its own school of thinking (which is also why demons and gods and angels almost inevitably fight one another whenever they meet). They are incapable also incapable of acting according to their opposite morality because they have no idea how to do it, and because their instincts will usually guide them in the opposite direction.

[QUOTE=Shienvien](Random: what creatures do get an afterlife? Do all at least somewhat intelligent animals get one? (Animals who are intelligent enough to like or dislike certain individuals, for example?) What about plants (or, at least, poor Anaxim)?)[/QUOTE]
Any being that meet the criteria for being classified as "mortal" - which includes just about every animal and monster in Reniam, not just the civilized species - is sorted into the two afterlives unless they are convinced that there is a different fate in wait for them. Plants - even Anaxim, regrettably - do not qualify as mortals and are not granted afterlives; their energy, memories and self simply disperses upon death to be recycled and reused by other plants, or by greedy liches or Xuhrl-njok that happen to be nearby... the two latter of which will erase their memories and selves upon consumption, whereas the former will allow them to continue existing as part of themselves.

[QUOTE=Shienvien]And I see about the deities not affecting their followers' location more specifically, and there being no division to regions present. I take that canonically, what specific deity you believe in has little effect on what your afterlife would be like?[/QUOTE]
Normally it won't no... well, not in a big way, at least. Someone who was a Favored One to a god during their life might be greeted by an angel in service to that god upon arriving there, and someone who reached the rank of either high priest or knight-paladin could even be lucky enough to be welcomed by the god itself, but beyond that it is the choice of the dead themselves how much they want to hinge their afterlives on their past religion. In the Lower Plane people who worshipped a demon lord will usually be tracked down much faster than others by the lord's demon minions and be... enthusiastically encouraged to become demon minions to that same lord themselves. And again, someone who was a high priest or knight-paladin to a demon lord might be greeted by the lord itself, for it to personally extend the offer to become a demon and join its legions. Small things, really.
