@Legion: All right, then... so they're basically humans with longer lifespans, one ethnicity of which has a skin color that is rather unusual to humans, but otherwise they are very much like humans? How does their population maintain itself between their long lifespans - which would usually implicate a long reproductive cycle - and their aforementioned warlike culture? Though I suppose with lifespans that long and a reproductive cycle short enough to replenish their numbers lost due to war, continuous war would almost be [I]necessary[/I] for them to avoid their population increasing uncontrollably to the point of their growth being entirely unsurstainable. (A small divergent thought of mine is that if they do require constant war like this and has been participating in such warfare, then they must either still have at least one other nation between themselves and the Xhurl-njok or only recently have expanded as far; if someone persistently showed aggression against the Xhurl-njok the way the Éireannach are described to, chances are that they would not last long before the Xhurl-njok decided to remove the annoyance they would represent.)
I also wonder just how genetically compatible these Éireannach would be with other races. They are described as being very humanlike, but with lifespans that are almost as long as those of penin... Interbreeding between races would be difficult to accomplish.

@ASTA: One thing I have to address immediately is the fact that I flinch when a species is described as having any kind of "[I]unnatural[/I]" property about them. It's probably just an exaggerated adjective in this case, but I object to the use of that in this context very strongly; no being that is not innately supernatural, such as immortals, have any kind of "unnatural" anything. Your del-korm are strong, I get that, but not unnaturally so. They have muscles, and they have strength proportional to those muscles unless empowered by magic, which I seriously doubt that the entire race has.
That little detail aside I quickly realize that the del-korm definitely would [I]not[/I] fit in as a race from the west. I think they should be a southern race instead, from the Malith Jungle or further; this is really the only place remote and unpopulated enough that creatures like these would be tolerated by the civilized races, and the only place with wildlife exotic enough to contain creatures of the caliber that the del-korm supposedly deal with.
Aside from that they sound like a very powerful race, and yet another one that would very quickly provoke hostile relations with most other nations. Their culture aside, however, I would like to know more about their racial properties; a bit more description in terms of what they look like and how they function on a more individual level, as well as their actual lifespan rather than just their life expectancy (the life expectancy of Niin is generally even lower than that of del-korm, but their natural lifespan is over two hundred years).

And with both races I find myself wondering: why would they travel all the way to Rodoria, a journey that would be very long and extremely perilous for either of these races? I would like a credible explanation to that, at least, before considering implementation into the universe.
