This is a thought I've had, since the Aifon and the Elves are descended from humans and can interbreed with humans. Kithra Kyriel (sp?) is half elven. Perhaps some of thier Aifon blood and genes are still floating around. Full blooded Aifon are extinct, no doubt about that, but consider this. Chances are that a small number of Aifon interbred with humans, producing half blooded Aifon and they had children and so on. What I'm saying is, that there may be some people who can actually trace thier genetic bloodlines to the Aifon. By now the mixture would be so dilluted that they wouldn't be able to breathe underwater like the Aifon did, but they could maybe have a small affinity for water or the sea and so they have a stronger connection than others. While the lore says that the Aifon were killed off, but this implies full blooded Aifon. Mixed parentage descendants likely escaped whatever it was that killed off the Aifon. This is just something to think about.
