Well, I never really envisioned the del-korm having any sort of afterlife, because I've come to realize that it conflicts with what their definition of life is. To them, life isn't something to be squandered or taken lightly, but should be used to carve one's legacy into the fabric of time so that later generations will remember you. Though, life should also be enjoyed to the fullest, and part of that is testing your physical or mental limits.

Reach new heights. Become the strongest, fastest, swiftest, and most intelligent and cunning hunter possible. Stuff like that. 

To believe that a treasured afterlife awaits them when they die would, at least in my opinion, make them lazy and make them think that their lives are disposable and/or replaceable with something better.

(this also has made me decide that del-korm are most definitely not immortal; it wouldn't fit them, but I did have some very strange ways of dealing with possible del-korm immortality where, because of their short life spans, del-korm were almost completely unaware of their inability to be die from old age. But, they probably live up to age three-hundred or so, which would make Claw--who is 120 years old--roughly middle age, and his mother--who is 180--just over middle age.)

It's why they place a [i][b]very[/b][/i] stern emphasis on deeds and accomplishments and why reputation is an actual currency in Malkor-Kurz (if you're known as a very undesirable person, people are less likely to want to deal with you, and being socially active in Malkor-Kurz is how you come to accumulate meaningful friendships and companionships, which inevitably lead to favors and advancement in del-korm society).
