Q: Do you have any thoughts on the Wind Whisperers tradition of death and how it might differ from (or be similar to) the other elven groups?
A: First and foremost, the Wind Whisperers ARE NOT AN ELF CULTURE like the Grim, the Aereni, and the Tairnadal. They don't have a lot of full-blooded elves and thus aren't shaped by some of the biological aspects of being an elf—notably the exceptionally long lifespan, which is part of why the pure elf cultures are so concerned about avoiding death. They are a KHORAVAR culture that from the start "fully embraced Lhazaar culture" and that they has had a steady influx of immigrants bringing their own traditions; the PRINCE is a Lyrandar excoriate who wasn't even born on the island. It's described as a haven for "young rebels seeking an escape from the smothering traditions of their houses" and its people are said to be "as wild and unpredictable as the wind itself."
So: consider the general rebellion against smothering traditions and the fact that the prince is an immigrant; the Wind Whisperers don't WANT to cling to ancient traditions and they aren't going to be obsessed with their ancestors. On the contrary, the Wind Whisperers *embrace constant change.* The fact that they are led by Koulton is proof that they are always looking to the immigrants to bring them NEW traditions and ideas; they don't want to force old beliefs on people, they want to adapt and incorporate to new ones. So the Wind Whisperers of the present day may have very different traditions than they did five hundred years ago, and THEY may have been quite different five hundred years before that. And, as you note, Orthoss isn't noted for Mabaran or Irian manifest zones, which drive the culture of the Aereni and the Grim.
So to address the specific question -- how do they approach death -- I'd say that they have a casual and comfortable relationship with death. They don't try to cling to their ancestors or their past; they are like the wind, ever flowing and moving forward. We are here and then we're gone, but the wind will always flow; not exactly a belief in reincarnation as much as a approach of "It's all going to be all right; don't try to fight the wind, allow it to carry you on to whatever lies beyond." But again, that's a general, casual idea because the Wind Whisperers HATE SMOTHERING TRADITIONS and are always open to change.
