In regards to nature, mothers eating their own young is extremely common... Evolutionarily, a fertile grown female is often far more valuable. The offspring most likely won't survive on their own, but the female can always have a new litter next month or year if she survives. Even with most social animals, the survival of fertile adults is usually heavily favored, since it is more beneficial to the species and community as a whole.

(Lions for one *very* often eat their young. If the pride gains a new head, eating all the young cubs is nearly the first thing he will do... Almost all rodents will eat their young when they become excessively threatened... Chimpanzees, which are normally herbivores, sometimes attack other chimpanzee groupings, and when they kill someone then, they will make an exception to their diet and cannibalize. With many species of fish, the young of the same species is a very significant portion of the diet. [i]Et cetera, et cetera, et cetera...[/i] Nature *is* cruel. Cannibalism and ritualistic murder were very common amongst some nature-peoples, too.)

And yeah, I don't see del-korm more evil than, say, cats or hamsters...

(Also, plants feel pain and communicate to one another, too... The chemical consistency of the other end of your law changes almost as soon as you start your lawn mower, and you won't even be anywhere near said plants yet. The "smell of freshly cut grass" is the smell of chemicals only emitted by grass plants in response to extreme stress; normally they smell different.)

[quote=Dark Jack]That aside, I'm sorry but I really need more, namely an explanation as to why they don't have afterlives. [/quote] From what you have said before, I gathered it is not impossible? And even before that, you have in several places, stated that souls do evolve over generations, too, not just physical forms? I would say it could be a "racial defect", a mutation that occurred once long ago that makes their souls fall apart after death rather than stay in a condition that would permit passing on or becoming a ghost? As in, their souls actually [i]need[/i] bodies to stay together? 
(I would, in general, suggest that everything that isn't impossible should be allowed for RP purposes, lest the process of integrating new ideas becomes grueling and starts killing motivation and hampering creativity. Didn't you yourself once say that your novels are yours only, but the RP here is the collaborative creation of us all?)

[quote=Dark Jack]For them to have anything akin to an ability to consume their opponents' voices to increase their own power, it would probably need to be explained as draining magical energy from them.[/quote] Yes, they are intended use the magical energy of those they defeat/kill... The only real question is how exactly the process of acquiring said magical energy goes.

[quote=Dark Jack]It seems like del-korm would have no moral compass with the way they work, meaning that their pursuit of "carving one's legacy into the fabric of time" could just as easily (or more easily, even) be accomplished by acts of cruelty as it could by acts of glory.[/quote] I think this is what the "reputation as currency" and related aspects are there for. Horrific acts cause hatred, and if you are hated so much, you will most likely be just killed off quite quickly.

[quote=Dark Jack]It's not something that is constantly relevant, no (in fact I did decide that the Seeds do not affect a being's personality unless one or both of them are missing, but are indeed solely a mechanic for determining afterlife and, in some cases, manifesting an aura of one alignment or the other in beings who exhibit exceptional growth of one of them), but they are there.[/quote] This is essentially what I meant with "not paying not much mind to it" when writing characters. As long as my character is alive, is not a demonspawn, and doesn't somehow get either seed (or both) removed they do not affect what my character does? Was a bit bad wording here. 

What does somewhat ... puzzle me, though, is the fact that several of the gods, who are supposed to only have a seed of good each (the renegade demon lord, Rilon, excluded) are either morally questionable (Deliph) or considerably more evil than good (Frenis). [With my personal set of morals taken as a basis, granted, but the basics should overlap with quite a lot.] Greed and selfishness are quite universally considered "evil" traits. Granted, there are many evil and/or questionable gods in various mythologies, but in those gods are (as a rule) not [i]supposed[/i] to be thoroughly benevolent...

Oh, and a point Legion did bring up: does the deity you believe in any way influence your afterlife in the canon? Assume you don't become demon/angel. (I assume most devils will just want more demon minions, though.) Do the deities have sort of regions for their specific followers that they designed (and which said followers are free to migrate out of), for instance?
