I always thought... this is the way things work in this world. Death isn't permanent until your lifeforce is completely gone. As long as there is a flicker of it, your body will be remade. The only thing that makes it seem to not make sense is that we live in the real world, and know that once the body dies, that's it. Take away that knowledge, and Carrion Fields method of death makes perfect sense. Because that's all your character knows.

I've always used a similar explanation for weapons with say, a fire attack not being magic. Clearly a weapon that burns would be magical, right? Well, yes, but only from our point of view. From a character in Carrion Fields point of view, there's really should be nothing wierd in a skilled smith making weapons that do all sorts of things we can't imagine.
