Btw, the lore post we're referring to is a $10 patron post Sierra made a while back called Lore Post: Death that discusses some of these issues. Thus, since it's OoC knowledge directly from Sierra, it's basically word of god on what the rules for souls and death are. Not that creators have never retconned that kind of thing, of course, but Sierra strikes me as the type who cares about consistency, and she didn't have to tell us anything about it if she wanted to play fast and loose with it. So I suspect the rules she laid out are actually rules.
